Can Atmospheric Water Generators Resolve Egypt’s Water Crisis?

Egypt faces an imminent water crisis which could jeopardize the country’s stability and regional dominance. Egypt is currently below the United Nations threshold of water poverty. The current water shortage in Egypt is 13.5 Billion Cubic Meters per year which is expected to continuously increase. According to hydrologists, a country is considered to be facing water scarcity if supplies drop below 1,000 cubic meters per person annually. Egyptian officials state there are currently around 570 cubic meters (150,000 gallons) of water available per person per year. This figure is expected to drop further to 500 cubic meters by 2025.

The UN is already warning that Egypt could run out of the water (Day Zero) by the year 2025. Furthermore, the river Nile is the main source of water with around 85 million Egyptians depending on it. The river Nile is the backbone of Egypt’s industrial and agricultural sector and it is the main source of drinking water for the population covering 95% of the annual freshwater budget. However, as Ethiopia (a Nile upstream country), plans to start filling its Grand Ethiopian Renaissance Dam by July 2020, this is expected to lower water to threatening levels in Egypt and negatively impact power generation at Egypt’s dam in Aswan which threatens Egypt’s water security.

Water Challenges in Egypt and Conventional Solutions

In addition, some of the major factors that play havoc with water security in the country are water losses due to the failure to rationalize water consumption, uneven water distribution, rising population, misuse of water resources, as well as the consequences of a higher standard of living, growth of industrialization, water pollution, the absence of actual control on factories disposal of hazardous waste materials in water, the increased use of chemicals in agriculture, inefficient irrigation techniques (mud and soil instead of sprinkler and drip irrigation), degradation of watercourses and drainage systems and the deterioration of the current water transmission pipelines, low public awareness of water scarcity and water quality deterioration.

Moreover, climate change effects on Egypt being a downstream river Nile country. Furthermore, challenges in cooperation with upstream Nile basin countries; besides, rising populations and rapid economic development in the upstream countries of the Nile (11 countries). All these factors are decreasing water quantity and quality in Egypt.

Conventional solutions for water resources include agricultural drainage water, desalinated brackish groundwater and/or seawater, and treated municipal wastewater. These resources represent merely 22.2% of the total available water resources and are generally used for agriculture, landscaping, and industry through specialized processes. Desalination is practiced on a small scale at present, mainly along the Red Sea coast.

AWG: A Promising Non-conventional Solution for Water Scarcity

Did you know that wherever air exists, water exists? At sea level, air contains roughly 1% water vapor, and even in the desert, a cubic area the size of a house can contain up to 16 liters of water, according to Harvard scientists.

Atmospheric Water Generator (AWG) is a device that extracts water from humid air. Water vapor within the air are often extracted by condensation which is essentially cooling the air below its temperature, exposing the air to desiccants (substances which absorb humidity), or pressurizing the air. AWGs are useful where pure water is difficult or impossible to get because there’s nearly always a little amount of water within the air which will be extracted. In contrast to a dehumidifier, an AWG is designed to render the water potable utilizing two primary techniques which are cooling and desiccants.

Policy Recommendations for AWG Implementation in Egypt

The potential of private sector involvement in water management in Egypt has been acknowledged by the Egyptian Water Policy (EWP) authorities by enhancing the participation of the public and private sectors with other civil society groups and organizations. The EWP sought institutional reform policy in water management by transferring public responsibilities to the private sector to improve the performance of the irrigation and drainage system. Still, the government has to facilitate the flow of funds directed to private water projects whether it be domestic or foreign investments.

The flow of funds is one of the major obstacles circumventing the involvement of the private sector in water projects in Egypt. This will speed up the process for the private sector to engage effectively in solving the water scarcity problem through innovative solutions such as the AWG devices. In addition, investment in research and development will further propel the Know-How in AWGs galvanizing several companies to adopt this sustainable solution. This will not only lower the device’s cost but will encourage the discovery of methods to overcome the challenges related to its use.

The setup and operation of an AWG device, even with a huge scale, is affordable for businesses and some households. However, for the neediest households, public utilities such as schools and hospitals, and small-scale farmers, the AWG solution can be expensive to set up. In addition, the operation of the device may be costly especially if the AWG device model is not solar- powered so it would require constant electricity to run. Accordingly, it is recommended that the government step in to subsidize the setup and operation of this device for vulnerable communities and customers. The former intervention in pricing is essential so as not to transfer the higher price of water to food which can disrupt economic stability.

In addition, for vulnerable people, who are so poor, that if they would have to pay the full costs they could not buy water, this may disrupt social stability. If subsidizing the setup of the AWG device is not feasible then it is recommended that the government adopts a BOS model. The government can buy the devices, operate them, and then sell them with installments to the civil society. This latter option should also be open for private sector companies, accordingly, the government should grant them licenses to undertake the BOS  of AWGs.

Furthermore, the current AWG devices require users to go to the machine, then bring the water back with them. This distribution system makes it difficult for those who are most in need to actually obtain the water generated for their communities which imposes an allocative challenge. It is recommended that given the government’s vision to remain fully responsible for the main infrastructures of the irrigation and drainage system, the government has to create alternative allocation methods to connect the water supply from the devices to end-users. This is another area where public-private sector cooperation can bring about several solutions such as the introduction of either small AWG devices called economic units or big scale devices both of which can serve households, farmers, and manufacturers according to their needs and financial abilities.

Finally, the supply of water in Egypt is about to become more problematic, it will touch the lives of all people.  If all stakeholders do not fully understand the gravity of the water scarcity situation in Egypt and fully cooperate this may jeopardize not only their well-being but their mere Being.

Efficient water management policies can definitely mitigate the severity of the water situation in Egypt but the problem can not be fully resolved without policies that engage the entire society in developing innovative water solutions such as the AWGs.

Pakistan’s Thirst for Water: Towards a National Sustainable Water Policy

Being the world’s 6th most populous country, Pakistan is home to about 210 million people. The growing population reduces average water availability every day. In 2017, Asian Development Bank reported that the agriculture sector of Pakistan consumes 93% of the water resources and contributes 21% – one-fourth – to the Gross Domestic Product. Pakistan Council of Research in Water Resources published a report titled “Water requirements of major crops in Central Punjab,” that has mentioned that over 60% of water is lost in transmission and applications. This implies that the agriculture sector that consumes 93% of water resources wastes two-third of it.

Water scarcity will affect agricultural activities in Pakistan leading to lower yields for a growing population, a matter of food security. Virtual water trade is exploiting our groundwater. Scientific journal “Nature” claims in a published paper of 2017 that Pakistan was the biggest exporter of groundwater in 2010. Wheat, rice and cotton are among the top five water-intensive crops and these are the most cultivated crops in Pakistan.

In a national newspaper, Dawn, it is stated that at the time of independence, per capita water availability was 5 thousand cubic meters, and now it has fallen below 1 thousand cubic meters. Pakistan Council of Research in Water Resources has predicted a severe water shortage by 2025 that will leave Pakistan dry if no measures are taken. It is not the first time international and national institutions are addressing water scarcity issues. World Bank issued a report in 2005 named “Pakistan’s water economy: running dry,” but we made no effective water policy.

Pakistan relies on Indus River, a single basin for its freshwater resources. Furthermore, being a semi-arid country, Pakistan receives an annual rainfall of less than 500 mm, most of which end up in a runoff. Groundwater pumping has also crossed the sustainable limit of consumption. According to the State Bank of Pakistan, Lahore is facing an annual reduction of 0.5 meters of the water table for the past 30 years. Urbanization has proved salt on injury as people are moving from rural areas increasing water consumption of limited water resources of urban areas. Wastewater is discharged without treatment, making groundwater unfit for use and biodiversity of water bodies is at stake.

The situation becomes more critical when water scarcity is accompanied by climate change as Pakistan ranks 15th in Global Climate Risk Index. According to the task force on climate change, 0.6°C rise of temperature was observed from 1901 to 2000 in Pakistan. Asian Development Bank writes an increase of 18-32% rainfall in the Monsoon period throughout 1960-2007 and sea-level rise of 1.1mm per year in the past century. Glaciers, a freshwater resource are retreating because of global warming. Rising temperatures and sea levels, droughts, flood events all are contributing to the instability of the country.

There is no single solution to the problem. Multiple strategies must be developed to tackle the problem. Policy reforms and good governance are the biggest challenges. The agriculture sector must be the focus to address water consumption as 93% of water is consumed by this sector. There is a dire need for maintenance of canals to decrease losses and metering infrastructure for pricing the quantity of water consumed. Drip irrigation and sprinkler irrigation must be introduced for the efficient use of water.

Rainwater harvesting is an attractive way to store rainwater that can be used for many household purposes other than drinking. Virtual water trade should be given due importance and our focus of exports must be changed from water-intensive products to water-efficient products. Desalination solves water shortage in coastal areas and rising sea levels. It is the need of the hour to find long-term sustainable solutions to the problem or otherwise, its effects will be devastating.

A Quick Glance at Plastics Recycling

Plastic consumption has grown at a tremendous rate worldwide. Plastics now play an increasingly important role in all aspects of modern life. and used in the manufacture of all sorts of items including protective packaging, mobile phones, domestic appliances, furniture items, medical devices etc. Each year around 5 trillion plastic bags are used worldwide with most of them ending up in landfills, dumpsites and water bodies. Due to the rising demand, the global plastic consumption is expected to reach 300 million tons by 2015. Per capita consumption of plastics in the Gulf countries is estimated to be 33 kg per annum which is much above the world average.

Disposal of plastic waste has emerged as an important environmental challenge and its recycling is facing roadblocks due to non-degradable nature. Because plastic does not decompose biologically, the amount of plastic waste in our surroundings is steadily increasing. More than 90% of the articles found on the sea beaches contain plastic. Plastic waste is often the most objectionable kind of litter and will be visible for months in landfill sites without degrading.

Recycling and reuse of plastics is gaining importance as a sustainable method for plastic waste disposal. Unfortunately, plastic is much more difficult to recycle than materials like glass, aluminum or paper. A common problem with recycling plastics is that plastics are often made up of more than one kind of polymer or there may be some sort of fibre added to the plastic (a composite).

Plastic polymers require greater processing to be recycled as each type melts at different temperatures and has different properties, so careful separation is necessary. Moreover, most plastics are not highly compatible with one another. Apart from familiar applications like recycling bottles and industrial packaging film, there are also new developments e.g. the Recovinyl initiative of the PVC industry (covering pipes, window frames, roofing membranes and flooring).

Polyethylene terephthalate (PET) and high density polyethylene (HDPE) bottles have proven to have high recyclability and are taken by most curbside and drop-off recycling programs. The growth of bottle recycling has been facilitated by the development of processing technologies that increase product purities and reduce operational costs. Recycled PET and HDPE have many uses and well-established markets.

In contrast, recycling of polyvinyl chloride (PVC) and other materials is limited. A major problem in the recycling of PVC is the high chlorine content in raw PVC (around 56 percent of the polymer’s weight) and the high levels of hazardous additives added to the polymer to achieve the desired material quality. As a result, PVC requires separation from other plastics before mechanical recycling.

Water Diplomacy in the Middle East for Transboundary Water Supplies

Increased pressure on transboundary water supplies as a result of rising economic and population needs, exacerbated by climate change processes, can have catastrophic consequences in the Middle East. Management of groundwater extraction from transboundary aquifers must involve sharing the amount of accessible water and preserving its quality in order to ensure that future generations will have access to safe groundwater supplies.

Transboundary water movement in the Middle East

The Middle East is afflicted by internal water mismanagement and conflicts. This necessitates not only the building of water governance institutions but also diverse engagement platforms and other water diplomacy techniques.

The negotiations about water management create the need for having water diplomacy that is a dynamic process that seeks to develop reasonable, sustainable, and peaceful solutions to water management while promoting or informing cooperation and collaboration among riparian stakeholders.

Water diplomacy topics are at the heart of discussions and conversations regarding the necessity of peace-building, cooperation between countries, and cooperation regarding transboundary surface and groundwaters: water diplomacy should not be restricted to diplomats and foreign policy experts, it is primarily the responsibility of water professionals who negotiate management agreements for shared water resources, but this should include representatives of NGOs to participate in transboundary water conversations, the involvement of these parts at all levels will help to establish is the most effective format of diplomacy.

According to experts, the sustainable growth of the Middle East and its political stability rely heavily on the region’s countries’ continued access to potable water. There are few recorded instances in which conversations on shared water resources led to prolonged efforts to address the underlying causes of an intrastate or interstate violent conflict.

Water Diplomacy Tracks

More technical professionals and actors in foreign policy need to have access to and be able to participate in transdisciplinary water diplomacy tracks and tools such varied discussion platforms, fact-finding missions, study tours, and joint scientific conferences.

Conventionally (water) diplomacy is seen as high-level interaction and dialogue between nation-states. Diplomacy is now defined according to various tracks which vary in terms of formality, actors involved, and purpose.

  • Formal Diplomacy (Track 1) Official/Formal communication between state actors with the authority and mandate to speak and make decisions on behalf of their governments or institutions.
  • Informal Diplomacy (Track 2 and 1.5) Dialogue between non-officials to build relations, resolve conflict, manage a crisis, or build trust, based on the agreed mandate, roles, and responsibilities. It can include officials in informal roles (Track 1.5), academics, NGOs, faith-based organizations, business partners, media, retired civil servants, and other ‘’insiders’’[1]

Transboundary water in the Middle East

The fact that 82% of wastewater is not recycled in the Middle East presents a tremendous opportunity to meet water demands. The region is anticipated to suffer the biggest economic losses due to climate-related water scarcity, between 6 and 14 percent of GDP by 2050.[2]

1. Israeli-Arab situation

In the Middle East as part of an arid region, groundwater reservoirs are regarded as the most dependable source of water, where the flow in the majority of perennial rivers is very variable due to seasonal fluctuations in rainfall quantity and distribution.

All groundwater reserves in the Middle East, are shared by at least two nations. And it will play a significant part in all peace conflicts. Water agreements are allotment is prominent in the present peace agreement between Israel and Jordan, as well as in the Oslo deal with Palestine.

Jordan-River

Israel and the Palestinians jointly exploit all main groundwater sources in the Middle East, including the coastal Mediterranean and highland aquifers. [3] The transboundary (Arava) Araba alluvial aquifer in the Jordan Rift Valley is shared by Israel and Jordan. The Arava Valley aquifer is shared by Jordan and Israel between the Red and Dead Seas.

Israel and Jordan have struck an agreement to jointly develop this international transboundary aquifer in the future, following a thorough examination of the aquifer’s future potential in terms of its quality and safe supply. This agreement is incorporated into the Israel-Jordan peace treaty of 1994.

However, Syria, Israel, Jordan, the West Bank, and Lebanon all utilize the Jordan River’s resources. The western Nubian sandstone aquifer is located beneath Sinai (Egypt) and the Negev desert.

2. Jordan and the Syrian Arab Republic

Implementation of agreements signed between the two countries, especially with regard to shared water in the Yarmouk River Basin. They also agreed to continue a study on the Yarmouk River Basin based on previous studies. Currently, the Joint Jordanian–Syrian Higher Committee is discussing how to make use of the Yarmouk River Basin water and how to protect Yarmouk water against depletion. Talks will also include preparations for winter and storage at the Wadha (Unity) Dam in the Yarmouk River.

The southern Syria Mountain ridge (Jabel Druze) partially recharges the Azrak aquifer, which spans over eastern Jordan.

3. Jordan-Saudi

Jordan and Saudi Arabia both extract water from the Disi aquifer. An agreement was signed between Jordan and Saudi, in 2015 that includes a mathematical model to be upgraded. With annual monitoring of the aquifer regarding existing wells which does not reflect the real picture, minimal changes have been encountered. The agreement includes a buffer zone of 10km on both sides have been agreed upon with the Saudi side. (10 km on each side).

4. Iraqi Turkey Syrian Situation

The river basin that supplies Syria and Iraq, the Tigris-Euphrates, is rapidly drying up. This large region is already struggling to provide for at least ten million people uprooted by conflict. And things could soon worsen; Iraq is approaching a point of crisis.

Both the Euphrates and the Tigris rivers originate in Turkey and flow to the Shatt al-Arab basin in southern Iraq. The Euphrates crosses Syria and Iraq, with Turkey and Syria contributing 90% and 10% to its water flow respectively. On the other hand, the Tigris flows from Turkey to Iraq, with Turkey, Iraq, and Iran contributing 40%, 51%, and 9% of its flow respectively [4]

Initiatives

EcoPeace Middle East’s “Good Water Neighbors” initiative in the Lower Jordan Valley is a well-known illustration of a bottom-up method. In this approach, Palestinian, Jordanian, and Israeli mayors and villages collaborate with their transboundary neighbors to rehabilitate their shared water resources.

water-islamic-culture

Academics and water professionals from Turkey, Syria, and Iraq participated in the Euphrates-Tigris Initiative for Cooperation (ETIC) to promote shared knowledge through data exchange and collaborative planning. As these many instances illustrate, the tools of water diplomacy may contribute to the creation of routes across societies for inclusive involvement and strong partnerships in water decision-making – a prerequisite for attaining a water-smart and peaceful global community.

The techniques of water diplomacy can help to the creation of paths between countries for inclusive involvement and strategic relationships in water decision-making, which is essential for attaining a water-wise and peaceful global community.

Suggestions and Solutions

The World Bank (2017) in a study of essential problems regarding water security raised three questions:

  1. Are the region’s water resources managed efficiently and sustainably?
  2. Are water services provided dependably and affordably?
  3. Are risks associated with water being effectively identified and mitigated?

Transboundary basins and aquifers in the Middle East can generate a network of hydrological, economic, and social connections between communities. Governments must work together to manage transboundary water resources. More cooperation is required, particularly to overcome the sensitivity to climate change consequences where water is already scarce.

Economic cooperation is essential. Agriculture, industry, energy, and water supply and sanitation, which rely heavily on water, must collaborate on a transnational level

Data voids must be filled. Governments in the Middle East must quickly enhance their systems for monitoring transboundary waters, particularly groundwater, and exchanging data with other governments as part of cooperation agreements.

Transboundary water management necessitates tackling a number of difficult environmental, socioeconomic, and political challenges that may incur substantial expenses, such as those related with infrastructure construction, the acquisition of monitoring equipment, and the creation of studies.

At various stages of management and development, distinct finance and financing sources may be necessary. Typically, national budgets should pay at least the core costs of joint bodies, mostly for reasons of sustainability. In some instances, national budgets may not be adequate to solve such difficulties, especially in underdeveloped countries where funding may be redirected to other priorities. In these situations, new and alternative procedures could be a viable choice for filling financial shortfalls.

Financial resources are required to fund institutional expenditures such as salaries and office space, as well as program expenses such as the collecting of data and information to monitor the condition and quality of water.

Can Inflatable Hot Tubs be Used in Winter?

Although most of the time, it is not recommended to use inflatable hot tubs in air temperatures below 40 degrees F, it has become common for most people to use mobile hot tubs in the wintertime. It turns out that the experience is relaxing.

Considering the diversity of the market of tubs nowadays, it might be frustrating for consumers to pick out the most suitable inflatable hot tub. Nevertheless, once you have figured out the best one and bought it, there are certain precautions you need to take.

inflatable-hot-tub-winter

Key Considerations

Testing inflating hot tubs has proven that these products can maintain their maximum water temperature well when it is below freezing in air temperatures, and you can enjoy them all winter. Before I go deep on the hardware issue, I would want to clarify the inflatable hot tub temperatures of the air rating and what it means.

The rating or the air temperature is the guarantee given by the manufacturer to the consumer that if they fill up their spa with cold water, the tub will increase the water to the maximum temperature and maintain it as long as the ambient temperature is equal to the tub’s rating (source: https://traditionalgardening.com/best-inflatable-hot-tub/).

Suitable inflatable hot tubs to use during winter

Intex 77in PureSpa Bubble Massage Spa Set

What would it be like to possess a mobile hot tub that you can easily set up anywhere? The product is many degrees inflatable than the normal inflatable pool and other hot tubs. It has a built-in treatment system that makes the product gentle on the skin and gives you a relaxing experience. At the top, there is an insulated lock that helps reduce the loss of heat and provide added safety features.

However, there are a few more things you need to know about PureSpa. To start with, the temperatures of water while using this product can only reach 104 degrees F. This is not a bad thing because some people can still be satisfied by this feature, but it won’t work for those who desire hotter temperatures.

Moreover, for this hot tub to function properly and achieve its temperatures, the external temperatures need to be at least 50 degrees. This can prove to be troublesome if you happen to plan to set it up in colder climates.

Bestway Hawaii Air Jet Hot Tub

This product provides you with the best spa experience ever. Its square shape gives the ultimate relaxation, and the 114 air jets massage feature gives you a luxurious treat. Usually, setting up an inflatable hot tub outside can prove risky, especially in areas where there are many trees, dirt, rain, or leaves falling off. Fortunately for people who choose to use Bestway inflatable hot tub, the product contains a leatheroid cover that protects it from everything. You can confidently leave your Bestway hot tub outside.

Using an inflatable hot tub in winter

1. Insulate the tub

Most spas contain a mat or disk sitting between the floor and tub’s spa, thus creating a heat barrier. But, this barrier cannot deal with cool temperatures, and therefore, it is vital to beef the barrier up before doing anything else.

2. Hook up a Heater

Put the tank containing propane inside the hot tub cover and run the hose to a Ecotank L5 tankless heater. You can either place it inside the housing or outside for a clear look.

3. Connect the pump with the hose

This procedure might need a hose clamp because you are supposed to link the pump to two hoses. Place the lengths of the hoses in the spa. The ecotank heats the water quickly.

4. Use the wired 12v switch to attach the pump to the adapter

This procedure seems a bit complex and requires the use of the instruction manual.

5. Put together the AC power adapter

Attach the Kaster 12v to the adapter and the pump so that the plugin adapter powers it. Once a plugin unit powers the entire system, your hot tub is ready to use.

Conclusion

To sum up, whether hot tubs can be used during winter can be answered by a qualified yes. There are various options for you in the market to get a suitable inflatable hot tub to help you enjoy the winter season. Once you find out the best that can work for you and understand the procedure on how to use it, then you will be able to enjoy your winter holidays.

Water Stress in the Mediterranean: Perspectives

For many years now, the Mediterranean has been facing problems leading to a situation of serious environmental degradation. An increase in the temperature and salinity levels has been recorded during the second half of the 20th century in the Mediterranean Sea. However, this increase does not follow progressive trend and periods of temperature alternation have been observed. Following several climate change scientific reports, sea level trend at the global scale is higher than at the regional scales.

mediterranean sea

Furthermore, in the regional scale there are other influence factors such the atmospheric pressure and the wind. In addition, the small rises in temperature registered in the Mediterranean Sea, would have been compensated with an increase in the salinity, even though this fact is uncertain owing a lack of historical data.

Nevertheless, we can establish a prediction for the future: The increase in the water stress in the Mediterranean basin (due to a higher evaporation rate and a decrease in rainfalls and water courses levels) will cause rise of salinity would made up for the raise in temperature.

Drought in the Mediterranean and Middle East, resulting from lack of rainfall, reduces runoff, thus also affecting, among other things, power generation. In combination with high rates of evaporation and lack of moisture, it alters soil properties making the soil less productive, thus holding back agricultural development, the backbone for the economy of the Mediterranean basin countries.

The main cause of the water stress suffered by the Mediterranean and Middle East is the increasing use of natural resources by the rising population and the higher demand for water per capita. This is not only because customs are being adopted that do not allow for balanced water use but also, and especially, because economic and industrial development in the region has turned its back on any type of sustainable management of resources and conservation of the natural environment.

Industrialization is not only responsible for the shortage of water but also for the high levels of pollution in the Mediterranean Sea which are destroying natural habitats. Over the last century, water has become a much-valued resource leading to disputes between different peoples, causing internal and even international conflicts.

Proper water management is necessary, especially because water is a limited resource in the Mediterranean and the Middle East. Before this is possible, it is necessary to create a greater awareness amongst society. Industries must become more respectful of the environment, national policies must be adopted to promote such industries and sustainable, equitable water management must be set up. The countries in the region must continue working together on research to resolve the problems of the Mediterranean. Fair, common policies must be adopted, preventing further international conflicts.

Note: This article is being reproduced with the kind permission of our esteemed partner Med-o-Med which has adopted a firm commitment to water use, not only because of its symbolic importance in Islam, but also because Islamic civilization was behind a real revolution in water use. The example survives even today in certain institutions, one such being the Valencia Water Tribunal in Spain which continues to function effectively today as it did in the past.

From Cost to Value: Why Solar Energy Financing Is a Strategic Move

Solar energy is often framed as an environmental choice, yet for many organisations the hesitation lies in cost. Upfront installation outlays can appear daunting, even when long-term savings are well recognised. Financing reframes this challenge, positioning solar not as a capital strain but as a strategic investment that enables businesses to spread expenditure while unlocking value sooner.

As energy prices remain volatile and sustainability expectations rise, structured funding has become central to how solar projects are assessed and approved. Renewable energy financing bridges ambition and execution, aligning cash flow with risk management and long-term operational goals. Against this backdrop, the following discussion examines how financing models can help organisations balance resilience with sustainability, all while the said organisations can position themselves for long-term competitiveness.

Turning Energy Spend into a Long-Term Asset

Energy costs usually disappear into operating budgets, offering little beyond short-term relief before the next bill arrives. Solar alters that dynamic by generating value over decades, creating a predictable stream of savings rather than a recurring expense. When financing is applied, those savings begin immediately, with repayments offset by reduced grid reliance rather than waiting years for the break-even point.

Rising grid prices further highlight the appeal of solar, as its fixed cost becomes increasingly competitive, insulating budgets from volatility. Over time, what begins as a managed expense evolves into margin protection. Unlike conventional energy contracts, solar provides compounding benefits without rigid lock-ins, transforming energy spend into a durable asset for growth.

Preserving Capital for Core Priorities

Large upfront payments force difficult trade-offs, especially for growing organisations. Financing removes that pressure by spreading cost across the same period the asset delivers value, ensuring investment in solar does not come at the expense of other priorities. As a result, capital that might otherwise be tied up in infrastructure remains available for hiring, market expansion, or technology upgrades that drive competitiveness.

This flexibility allows sustainability initiatives to support growth rather than compete with it. During periods of economic uncertainty, that breathing room can be decisive and enable organisations to maintain momentum instead of delaying projects. Ultimately, financing ensures solar adoption strengthens rather than strains long-term business objectives.

Managing Risk Through Structure, Not Guesswork

Risk is often framed as technical uncertainty, yet financial timing carries equal weight. Financing structures help distribute exposure more evenly by aligning repayments with production and usage patterns, ensuring obligations match the asset’s performance. When bundled with maintenance plans, warranties, and insurance, these agreements reduce surprise costs and simplify oversight.

For decision-makers, this translates into clearer visibility over lifetime obligations and a more predictable financial path. Risk is managed proactively rather than reactively, giving organisations greater confidence in long-term strategy. Structured financing, therefore, turns risk from a disruptive variable into a managed component of sustainable growth.

Aligning Long Asset Lifespans with Financial Planning

Consider an organisation that budgets in three-year cycles yet commits to a solar system designed to perform for twenty-five years. The mismatch forces immediate planning horizons to absorb extended obligations, straining cash flow and skewing priorities. Here, green energy financing bridges that gap by matching repayment periods to the system’s productive lifespan, ensuring obligations align with the value delivered.

Once repayments conclude, the asset continues to generate low-cost energy, compounding returns year after year. This perspective shifts energy planning away from annual cost control toward enduring value-optimisation. For leaders focused on durability rather than quick wins, financing transforms solar from a budgeting challenge into a cornerstone of sustainable financial planning.

Capturing Policy and Incentive Benefits More Efficiently

One of the fastest ways to strengthen the business case for solar is through incentives. Tax relief, rebates, and feed-in arrangements can dramatically improve returns, yet navigating them often requires expertise and time. Financing providers from both the public and private sector simplify this process by embedding policy benefits directly into project terms, ensuring organisations capture value without added administrative burden.

In Singapore, programmes such as SolarNova illustrate how government support accelerates deployment, giving projects a head start on savings. In the banking sector, UOB’s regional U-Solar programme also makes sustainable solar energy financing solutions accessible to both businesses and individuals across ASEAN.

When policies evolve, financed projects can adapt through refinancing or revised terms, keeping benefits aligned with changing regulations. This agility is especially valuable in markets where energy and sustainability frameworks continue to mature, allowing organisations to stay ahead of both compliance and opportunity.

Strengthening Credibility with Stakeholders

For many stakeholders, sustainability is no longer a soft expectation but a hard requirement. Investors, regulators, and customers increasingly demand evidence that environmental responsibility is embedded in operations, not just promoted in messaging. Financing solar projects provides that evidence in measurable terms, turning commitments into visible assets that demonstrate accountability.

This credibility extends beyond reputation. Organisations that integrate renewables through financing often gain preferential access to capital, stronger investor confidence, and improved standing with regulators. In Singapore, the Monetary Authority’s sustainable finance agenda underscores how renewables are becoming central to capital markets, shaping how funds are allocated and evaluated. Aligning with such frameworks elevates credibility by embedding sustainability into strategy, strengthening trust and signalling readiness for evolving capital markets.

Beyond a mechanism for affordability, solar energy financing is a lever for strategic transformation. Organisations that adopt structured models secure resilience in volatile markets while positioning sustainability as a driver of competitiveness. The advantage lies in acting early: leaders who embrace financing today capture enduring value, thus ensuring their organisations remain adaptive and credible in a future where growth and sustainability reinforce one another.

Top Ways to Achieve Zero Waste at Your Home

Zero waste is a movement that has been vastly popularized by millennials. It is essentially a culture of not leaving anything behind. With the condition that our planet is in right now, in terms of trash, it makes a lot of sense. People are becoming more conscious of their footprint and it’s a great thing.

Although a lot of people know about it, not many actually commit.

  • I could never stop using tissues, I’m allergic to pollen!
  • I love snacks too much, this is impossible.
  • Someone else will take care of the planet, I don’t have to do it.

People come up with all these excuses, but what they really need to do is assess the amount of trash they make. We all leave a massive scar on our home planet that will take centuries to heal. So, is it really that hard?

In this article, we will look into the ways you can make your home zero waste (or at least reduce your carbon footprint). Let’s dive in!

1. Reduce

We all have heard this popular motto by now: reduce, reuse, recycle. But what does it actually mean?

First, you have to analyze the items in your home. Think about what you use on a daily basis and what items are just lying around waiting to get tossed. That’s the reduce part. But reducing doesn’t necessarily mean throwing away. A lot of things have much more uses than you might think. If it says “vinegar” on the packaging, it doesn’t mean that it cannot be turned into a multi-purpose cleaner.

Remember all the papers you have lying around? Your old essays, books, and lecture notes don’t need to take up that much space. So, start with decluttering. Pile up all the old paper, plastic and everything that doesn’t have a use in your household. But read till the end before tossing it all in the trash!

2. Reuse

Now, think again. Which of the things you don’t need can have another life? You can look up upcycling projects if you like to DIY. Donating your old clothes and your child’s toys is always a good thing to do. Our generation is more likely to toss something, while our parents would always mend and fix the old things.

We should all learn from them! If something is broken, it doesn’t mean that it’s never going to work again. Call your dad, he’ll know what to with a broken kettle or a TV remote. If you replace an item, there’s no guarantee that the new one won’t break in the same amount of time. But if you fix it, you will boost your self-esteem, not to mention the broken item working again.

3. Recycle

If you live in a big city, recycling is as easy as it can be. A recycling bin is probably right around the corner. It only takes a little more walking than usual. Almost every plastic container is recyclable, so zero-waste doesn’t mean you can’t buy snacks anymore.

reduce_reuse_recycle

You just need to learn some ground rules:

  • Wash the plastic thoroughly;

If you put a container that has a small trace of food in it into a recycling bin, the whole batch will be wasted.

  • Recycle it right.

Every recyclable plastic item has a number on it. That number indicates the kind of mix used. You have to toss the right things in the recycling center for them to get recycled properly.

  • Research.

Find the closest place to you that accepts organic waste. If you live in a house, make place for a compost pile. If there isn’t enough space, you can buy a composting bin, or make it yourself.

How Do I Get Started?

You don’t have to quit cold turkey. But once the idea gets planted into your mind, you will see yourself becoming more mindful of what you buy and what you toss. Start little by little. Follow these simple steps below.

  • Buy in bulk

If you buy in bulk, you won’t suddenly run out of something. Making a pantry essentials list is also beneficial.

  • Bring your own containers or bags to the store

Even if you don’t have those fancy reusable bags, it’s not a problem. Everybody has plastic bags lying around. Keep a few in your purse in case you go to the grocery store after work. Plastic is durable and reusable.

  • Have containers for food takeout as well
  • Refuse the unnecessary

Do you really need to pick up a receipt at the store? What about that flyer from a promoter in the street? Politeness should not be the reason to bring trash to your home.

  • Use the same cleaner for everything

A whole shelf of cleaners for every single surface is just marketing. If you look at the ingredients, they are mostly the same. Dilute vinegar with water and use that to clean surfaces in your home. You can even use it on glass, it doesn’t leave traces.

  • Stop buying single-use items;

Paper towels are not a necessity. You can use regular towels for as long as you want. Just wash them regularly.

Wrapping Up

There are many brands that support the zero waste movement. You don’t have to suddenly start making beauty products yourself if you have never done that before. You can just take your own containers to the store, or bring the old one for a refill. Once you start doing that, you will see that you’re not alone. If you get a friend or your whole family to join you, the journey to zero waste will become a walk in a park!

The Promise of Seawater Desalination in Algeria: Perspectives

Algeria is one of the countries most exposed to water stress in the world. Classified as arid and semi-arid, it relies heavily on limited freshwater resources, with overexploited aquifers and dams often at critical levels during recurrent droughts. In response to this reality, the Algerian government has made seawater desalination a major strategic solution to secure potable water supply while alleviating pressure on natural freshwater resources. This approach goes beyond merely meeting human needs: it also potentially contributes to the preservation of terrestrial, marine, and freshwater ecosystems, in line with the objectives of the Kunming-Montreal Global Biodiversity Framework adopted in 2022, which includes 23 operational targets to be achieved by 2030 [1–3].

seawater desalination plant in algeria

Algeria’s trajectory in desalination is already significant. At the beginning of the decade, the country had about twenty desalination plants along its coast, producing approximately 2.1 to 2.2 million cubic meters of desalinated water per day, covering nearly 17% of the nation’s total potable water consumption [4,5]. Under its national strategy, this capacity has been rapidly expanded: production reached approximately 3.7 million m³/day by the end of 2025, covering about 42% of potable water needs for a population estimated at around 47 million people [4,6].

The ten-year plan aims to reach 5.6 to 5.8 million m³/day by 2030, which would increase desalination’s share to around 60% of national potable water demand [4,7]. These figures illustrate how desalination has become a pillar of Algeria’s water policy, with plants averaging 300,000 m³/day each, deployed from the western to the eastern coastline [4].

Why Desalination Reduces Pressure on Freshwater Resources

In a country like Algeria, where aquifers are not renewable in the short term and rainfall is irregular, relying solely on continental freshwater would accelerate ecological degradation and resource scarcity. Desalination offers an alternative: tapping into the vast Mediterranean marine reservoir to produce potable water, relieving pressure on aquifers and dams and allowing these sources to be redirected to essential ecological needs [2,3].

By reducing direct withdrawals from natural freshwater reserves, desalination acts as a lever to support ecosystem services linked to aquatic environments, particularly wetlands that serve as nurseries for many species, rivers with ecological flows vital for fish and invertebrates, and riparian areas important for terrestrial species. This reduction in withdrawals contributes to several of the Kunming-Montreal Framework targets, notably those aimed at reducing direct pressures on ecosystems (Target 1 and Target 3) [1,2]. In a country where some aquifers are overexploited by more than 50%, reducing dependency on these sources helps maintain a minimum level of availability for nature [3,4].

Desalinated Water as a Vector for Water Security and Climate Adaptation

Algeria’s climate is marked by worsening droughts, a trend observed across the Mediterranean basin and attributed to climate change. These events cause severe shortages in inland regions, such as the Tiaret province, where some dams have completely dried out at times [5]. In this context, having an alternative water source like desalination strengthens socio-ecological resilience, as communities are no longer solely dependent on irregular rainfall or variable reservoir levels.

Furthermore, integrating desalination into a comprehensive water management approach combining desalination, treated wastewater reuse, demand management, network efficiency, and watershed protection better aligns sectoral policies with international conservation commitments. This integration directly addresses Target 14 of the Kunming-Montreal Framework, which calls for incorporating biodiversity and its values into policies, plans, and development processes [6].

Interactions with Terrestrial, Marine, and Freshwater Ecosystems

The impact of desalination on biodiversity is not limited to reducing pressure on freshwater resources: it also has direct and indirect effects on terrestrial and marine ecosystems. On land, increased groundwater availability benefits wetlands, riparian forests, and grasslands dependent on stable water levels. In the marine environment, however, environmental constraints exist, as desalination produces concentrated brine and sometimes chemical residues. If discharged without proper dilution, these effluents can increase local salinity, affect benthic microhabitats, and disrupt the reproduction of certain marine species [2,3]. This issue aligns with Target 7 of the Kunming-Montreal Framework, which aims to reduce pollution risks to levels non-detrimental to biodiversity.

For desalination to have an overall positive effect on marine biodiversity, brine discharge systems must be optimized with controlled diffusion, renewable energy used to reduce the carbon footprint, and strict environmental impact assessments conducted for each project to protect sensitive coastal areas [12].

Socio-Economic and Ecological Co-Benefits

The expansion of desalination goes beyond environmental benefits: it also generates significant socio-economic advantages. A more stable and diversified potable water supply improves access for citizens and supports key sectors such as agriculture, industry, and coastal tourism without increasing withdrawals from aquifers or rivers [4,7].

Additionally, when desalinated water feeds urban networks directly, pressure on natural basins decreases, freeing water to maintain ecological flows and ensure the survival of species dependent on aquatic habitats [1,2].

Towards a Sustainable Transition: Innovation and Environmental Governance

The role of desalination must be considered within a systemic vision integrating technological innovation, environmental governance, and social participation. Innovation improves energy efficiency, reduces costs, and mitigates environmental impact. Governance involves inclusive planning, where decisions on plant locations account for local challenges, sensitive biodiversity areas, and community needs [6,12].

Conclusion

Expanding desalination in Algeria is more than a response to a water crisis: it is a resource management tool that, if well designed, contributes to ecosystem protection and the achievement of Kunming-Montreal Framework objectives. By reducing pressure on aquifers and surface waters, supporting integrated policies, and minimizing impacts on marine environments through innovative management, desalination represents a sustainable and multifunctional approach.

Impact of Urban Trees and Forests on Greenhouse Gas Emissions

The fight against climate change has placed urban trees and forests at the heart of mitigation and adaptation strategies, to the point that tree planting is often perceived as a simple, visible, and widely accepted solution for reducing greenhouse gas emissions. In many countries, urban greening programs are expanding, with tree-lined streets, boulevards, and public spaces, while large-scale reforestation and forest restoration initiatives are prominently featured in Nationally Determined Contributions (NDCs) under the United Nations Framework Convention on Climate Change (UNFCCC).

lush greenery in a modern city

This situation raises a central question: does planting trees along streets genuinely contribute to reducing greenhouse gas emissions, or are forests essential to achieve a meaningful climate impact? The answer is neither binary nor ideological, but rather grounded in a scientific analysis of carbon sequestration mechanisms, orders of magnitude, and international experience.

Trees, whether urban or forest-based, capture atmospheric carbon dioxide through photosynthesis and store it as carbon in their aboveground biomass, root systems, and indirectly in soils. This fundamental principle is emphasized by the Intergovernmental Panel on Climate Change, which identifies terrestrial ecosystems as major carbon sinks capable of absorbing approximately 30% of annual anthropogenic CO₂ emissions worldwide [1]. However, sequestration capacity depends strongly on ecological context, vegetation density, available surface area, and the duration of carbon storage.

In urban environments, trees planted along streets, in parks, and in public squares do contribute to carbon sequestration, but in quantitatively limited ways. According to estimates by the Intergovernmental Panel on Climate Change (IPCC) and the Food and Agriculture Organization (FAO), a mature urban tree absorbs on average between 10 and 40 kg of CO₂ per year, depending on species, age, and growing conditions [2]. This absorption remains modest when compared with overall urban emissions, which are dominated by transport, buildings, and industry. Nevertheless, the primary climate value of urban trees lies in their indirect effects.

By lowering local temperatures through shading and evapotranspiration, trees mitigate the urban heat island effect, resulting in reduced demand for air conditioning and, consequently, lower emissions associated with electricity generation. Studies conducted in the United States and Europe indicate that urban vegetation can reduce building energy consumption by 5 to 20% during heatwave periods [3].

Urban trees also play an important role in climate change adaptation by improving thermal comfort, air quality, and population resilience to heatwaves, which are among the deadliest climate-related hazards. From this perspective, their contribution to greenhouse gas reduction must be assessed systemically, incorporating avoided emissions and broader social and health co-benefits. The United Nations Environment Programme (UNEP) has emphasized that the climate value of urban trees is often underestimated when assessments focus solely on their direct carbon sequestration capacity [4].

By contrast, natural forests and large-scale forest plantations constitute carbon sinks of an entirely different magnitude. One hectare of temperate or Mediterranean forest can store between 100 and 300 tonnes of carbon in biomass and soils and absorb between 2 and 10 tonnes of CO₂ annually, depending on forest type and development stage [5]. Forest soils, often overlooked in public debates, can represent a carbon reservoir equal to or even greater than that of aboveground biomass. The destruction or degradation of forests releases this stored carbon into the atmosphere, which explains why deforestation accounts for approximately 10 to 15% of global greenhouse gas emissions [1].

International benchmarks clearly illustrate this difference in scale. China’s massive reforestation program, implemented since the 1990s and often referred to as the “Great Green Wall,” has restored tens of millions of hectares of degraded land. According to the FAO, these efforts have significantly increased China’s national carbon sink, offsetting part of the emissions associated with the country’s rapid industrialization [6]. Similarly, Brazil, despite ongoing challenges related to deforestation in the Amazon, remains one of the countries with the highest forest carbon sequestration potential worldwide, and its forest policies have a direct impact on the global carbon balance.

At the urban scale, cities such as New York, London, and Paris have implemented ambitious tree-planting and urban forest strategies. New York’s “MillionTreesNYC” program, which aimed to plant one million trees over ten years, provides a well-documented example. Evaluations show that while the direct impact on CO₂ emissions remains limited relative to the city’s total emissions, the indirect benefits in terms of energy savings, public health, and climate resilience are significant [7]. Paris, through its Climate Plan and urban greening strategy, also relies on urban trees to cope with heatwaves, while acknowledging that carbon neutrality cannot be achieved without structural actions in the energy and transport sectors [8].

Another relevant benchmark can be found in Nordic countries such as Sweden and Finland, where sustainable forest management has long been integrated into climate strategies. These countries combine extensive forest cover, responsible timber harvesting, and low-carbon energy policies. Forests play a dual role there: acting as carbon sinks and providing biomaterials that can substitute for fossil-based materials and energy sources, thereby further reducing emissions [9].

In arid and semi-arid regions, the issue takes on a different dimension. Water constraints limit tree growth and forest density, requiring adapted approaches. The African Great Green Wall initiative, aimed at restoring degraded landscapes across the Sahel, demonstrates that reforestation and agroforestry can contribute to carbon sequestration while strengthening food security and the resilience of local communities [10].

Khalidiyah Park in UAE

In Algeria, the Green Dam project represents an emblematic reforestation policy designed to combat desertification, stabilize soils, and create a long-term carbon sink. In this context, urban trees, while valuable for improving urban comfort, cannot replace large-scale ecological restoration efforts.

Comparative analysis therefore shows that urban trees and forests do not serve the same climate objectives, even though both contribute to addressing climate change. Urban trees are primarily tools for adaptation and indirect emission reduction, while forests constitute central levers for long-term mitigation. Confusing these two scales may lead to unbalanced climate policies, where highly visible but quantitatively limited actions are overemphasized at the expense of more structural strategies.

International organizations stress the need for an integrated approach. The IPCC recalls that nature-based solutions, including reforestation, ecosystem restoration, and urban greening, cannot on their own offset current greenhouse gas emissions, but they are an essential complement to drastic reductions in fossil fuel emissions [1]. FAO and UNEP further emphasize that plantation quality, species diversity, long-term management, and community involvement are critical conditions for ensuring genuine climate benefits [2,4].

Bottom Line

Planting trees along streets does contribute to reducing greenhouse gas emissions, but in an indirect and limited manner, whereas forests remain indispensable for achieving significant climate impacts at national and global scales. The challenge is therefore not to choose between urban trees and forests, but to integrate them into a coherent, hierarchical strategy adapted to ecological and socio-economic contexts. In a world facing climate emergency, trees must not be treated as mere green symbols, but as components of climate policies grounded in science, scale, and sustainability.

Sustainability and Energy Efficiency: Key to Affordable Housing

To be affordable, houses must be designed and built embracing strong principles of sustainability. Ensuring houses are energy-efficient may increase upfront construction costs a bit, including the costs of superior tools and equipment and professional architectural and mechanical engineers services, but the long-term benefits and future cost-efficiency are what matters.

Non-believers think that it is an oxymoron to combine the idea of sustainability and affordability. But, the fact is that when homeowners are able to spend less on their energy bills they can budget better for repairs and maintenance, which intrinsically improves the durability and longevity of their houses.

In many countries, there are now codes and regulations that must be met when homes are built, up-graded, or renovated. Additionally, many consumers are embracing the concept of sustainable homes, which impacts on the real estate market, with an increasing number of people opting for homes that are water- and energy-efficient.

Then there’s the question of what “affordability” is – because there is a tremendous difference in terms of levels of affordability from high-income to relatively poor households.

International Affordability of Houses

Demographia, a not-for-profit organization that rates housing affordability in metropolitan areas worldwide, recently released its 16th annual, the International Housing Affordability Survey: 2020. Even though there are major markets in the U.S. that are unaffordable, the U.S. has the most affordable housing costs overall.

Focusing on affordable housing during 2019, the report looks at major housing markets in Australia, Canada, China (Hong Kong), Ireland, Singapore, the UK, the U.S., and Russia. It also notes that middle-income housing has increased in several emerging economies including several Central American countries, the urban fringes of Mexico, Chile, Thailand, Indonesia, Malaysia, and the Philippines.

However, while poverty has reduced during the past two centuries as a large middle-class has developed globally in the traditional Western markets, the report indicates that the standard of middle-class living is under threat. This is primarily because of the rising costs of living over the past two decades. And, of course, house prices generally have increased which means there is more unaffordable housing, and this creates enormous hardships – although, in reality, it is the house price-to-income ratio that matters.

Briefly, the most affordable housing markets are found in the U.S., lead by Rochester in New York State, Cleveland in Ohio, and Oklahoma City is Oklahoma. Canada, Singapore, the U.K., and Ireland also have affordable markets, but nowhere near the U.S. The most severely unaffordable are in Australia, New Zealand, and Hong Kong, although there are also 14 (out of 56) major markets in the US, two (out of six) in Canada, and eight (out of a total of 21) in the UK that are seriously unaffordable.

In Russia, housing is generally half the price to that in the U.S., and it ranges from “mostly affordable” (in 12 markets) to two – Moscow and Saint Petersburg – that are “seriously unaffordable”.

Within the context of the countries studied, Hong Kong is the least affordable place to live, followed by:

  • Vancouver in British Columbia, Canada
  • Sydney, New South Wales, Australia
  • Melbourne, Victoria, Australia
  • Los Angeles, California, U.S.
  • Toronto, Ontario, Canada
  • Auckland, New Zealand
  • San Jose, California, U.S.
  • San Francisco, California, U.S.
  • London, UK
  • Honolulu, Hawaii, U.S.

So how can sustainability and energy efficiency improve affordability?

Relationship Between Affordability and Sustainable

To be affordable, houses must be designed and built to last. If construction is energy-efficient it will reduce the long-term costs of maintaining a house and improve its durability particularly in terms of issues that are related to damp. With this in mind, authorities worldwide have introduced various mandatory sustainability  measures for home builders. Many are also encouraging voluntary sustainability measures and offering resources to improve sustainability, particularly in relation to energy efficiency and water resourcefulness.

In a paper titled An Examination of the Relationship Between Sustainability and Affordability in Residential Housing Markets, Dr. Carolyn S. Hayles, an academic with a special interest in sustainability, attempted to unravel the relationship between sustainability and affordability and analyze whether reducing the life costs of owning a home would be driven by the market, by legislation, or by consumers.

At the time (2006) Dr. Hayles, who is currently a senior lecturer at the Cardiff School of Art and Design, was lecturing in sustainable construction and green building design in Melbourne Australia and her study focused on housing affordability in Australian cities. With Melbourne and Sydney ranking (even then) as two of the most unaffordable housing markets, and Adelaide, Hobart, Brisbane, and Canberra ranking among the 20 least affordable cities in the world, she compared Australian sustainability measures to those adopted in North America, the United Kingdom, and New Zealand.

One of the issues she highlighted was the fact that housing developers, financers, and consumers needed to change their approach to sustainable housing projects because they can effectively:

  • Lower operating costs
  • Reduce energy bills by about 30% by making energy-saving improvements in building design
  • Improve comfort through better design and energy efficiency
  • Improve health through improved ventilation systems and the use of non-toxic or at least less-toxic materials

Above all, sustainable housing can meet the needs of all sectors of society and should help to make entry-level housing attainable for even low to medium-income families.

Perhaps ironically, Victoria in Australia has been promoting sustainable housing, for many years, as a means to bring about longer-term affordability. While other states initially required a 4-star rating, Victoria demanded a higher 5-star rating for new builds. The latter assesses the energy performance of houses in terms of the building fabric (including orientation, design, window size and orientation, and insulation), conservation of water, rainwater harvesting, and solar water heating. But, while 5-star houses are “better”, this is just a starting point for sustainability and therefore affordability.

In the UK the Building Research Establishment (BRE) Environmental Assessment Method (BREEAM) has been used for decades to review and improve the environmental performance of buildings. The residential version, EcoHomes provides an authoritative rating for new and renovated homes and is aligned with mandatory building regulations. BREEAM assesses the performance of housing in every possible way including energy use, health and wellbeing, water efficiency, and life-cycle impacts of materials.

While the USA and Canada have variable requirements in different states and provinces, the national approach throughout North America is to rely on building codes. Leadership in Energy and Environmental Design (LEED) is the rating system used for homes. LEED assesses the efficient use of land resources, building construction, energy and water resources, as well as resources in general, and the quality of the indoor environment and its ability to safeguard the health of occupants. The U.S. Environmental Protection Agency (EPA) Energy Star Program, which can be used to promote homes as energy-efficient and affordable, is widely used throughout North America.

New Zealand, where the BRANZ Green House Scheme is used for rating, also relies on building regulations and codes. BRANZ assesses housing performance in terms of energy use, the sustainability of materials, water economy, waste disposal and recycling, transport links, and health-related issues.

Overall, the UK, USA, Canada, and New Zealand have a more advanced approach to sustainable, affordable housing because they have:

  • Strict building regulations
  • Established rating systems that have been in place for a long time
  • More public and supported housing schemes that are driven by affordability
  • Sustainability driven by energy efficiency
  • Significant financial investment in schemes and initiatives

But, there is evidence that, unless consumers understand that by operating their homes in a way that is energy efficient they will benefit themselves, by saving money, and the environment, they aren’t going to make energy-efficiency a priority, even a factor, when buying or renovating a home.

Ultimately, says Dr. Hayles, to be affordable, houses must be designed so that consumers can identify the value of performance outweighing the financial cost.

Climate Justice and Environmental Justice – Two Concepts for One Challenge

Science keeps showing that as the effects of climate change get worse, extreme weather events are hurting developing countries a lot. This is especially true in Africa and Asia. Over half of Africa’s people would be at risk of not getting enough food if global warming reached 2°C. As it is, we have already reached about 1°C above pre-industrial levels (1850–1900). If things keep going the way they are, global warming is likely to reach 1.5°C between 2030 and 2052.

similarity between climate justice and environmental justice

From 1990 to 2015, the poorest half of the world, which is the most vulnerable to the effects of climate change, was responsible for only 7% of the world’s greenhouse gas emissions, according to research by Oxfam, an international organization that works to fight poverty. Still, more than half of it is caused by the richest 10% of the world’s people. Since 1751, when the industrial revolution began, the countries that are now the United States and the European Union have been responsible for 47% of the world’s carbon emissions, while all of Africa and South America have only been responsible for 6%.

One of the important examples is Sub-Saharan Africa, which is responsible for less than 1% of global emissions, and will probably suffer the most from the effects of climate change, which has already caused people to move and could soon lead to conflict over dwindling resources.

Definition of Climate Justice

Climate justice is a concept that has turned into a movement to address climate inequality, which is the difference between who is causing the climate crisis and who is paying the most for it. People who want climate justice don’t just want polluting countries to stop doing what they’re doing; they also want them to pay for the damage they’ve done and will continue to do as the effects of what they did in the past are felt on the planet.

“Climate change is happening now and to all of us, No country or community is immune,” said UN Secretary-General António Guterres. “And, as is always the case, the poor and vulnerable are the first to suffer and the worst hit.”

Climate change’s consequences will not be shared evenly or fairly by rich and poor, men and women, or older and younger generations. As a result, there is a growing emphasis on climate justice, which examines the climate situation through a human rights perspective and holds that by working together, we can create a better future for current and future generations.

The concept of climate justice examines the moral dimensions of climate change. Applied ethics, research, and activism employing the term approach anthropogenic climate change as an ethical, legal, and political concern, as opposed to a solely environmental or physical one.

This is accomplished by linking the causes and effects of climate change to conceptions of justice, including environmental and social justice.

Climate justice addresses issues such as equality, human rights, communal rights, and historical climate change obligations. Climate justice activities may incorporate the expanding body of worldwide legal action on climate change challenges.

These disparities in conceptions of climate justice are significant because they have grave ramifications for the countries, regions, and communities on the front lines of climate change’s effects and are becoming increasingly evident in efforts to speed de carbonization. Given the narrowing window for effective actions to avoid the worst impacts of climate change, immediate action is required.

Mary Robinson, the former President of Ireland and the current Chair of the Elders: Climate justice “insists on a shift from a discourse on greenhouse gases and melting ice caps into a civil rights movement with the people and communities most vulnerable to climate impacts at its heart. Stressing the importance of intergenerational partnerships where young people are seen as “means of implementation” and “creators of opportunities” and not just beneficiaries.

Why Climate Justice?

Multiple definitions of climate justice reflect the fact that the causes and impacts of climate change, as well as attempts to combat it, raise ethical, equity, and rights concerns.

Justice is about justice, equity, impartiality, and doing what is right from a moral standpoint. If something is unfair, unequal, immoral, or excessively biased (particularly against the poor or in favor of the powerful or otherwise privileged), it may be termed unjust. We define climate justice generally as the fairness, equity, and propriety of climate change measures.

There are justice components to the three key areas of climate policy:

  • mitigation (emission reductions),
  • adaptation (impact management), and
  • loss and damage (dealing with the residual adverse impacts after the adoption of mitigation and adaptation).

In light of these factors, it is evident that climate change is fundamentally a matter of justice: injustice is at the foundation of its causes, at the heart of its repercussions, and is crucial to the development and implementation of effective policies to minimize the related dangers. “It would not be an exaggeration to say that climate change is swiftly becoming the biggest injustice ever witnessed, experienced, and perpetuated throughout the entirety of human history” (Harris 2019: 13).

What is Environmental Justice?

Most environmental justice movements and intellectual debates intersect on three key ideas or themes:

  1. Anti-racist environmentalism(s) that characterized the 1980s and 1990s, linking demands for social justice and fairness to ecological problems and environmental harms such as pollution;
  2. Demands in the 1990s to recognize the ‘ecological debt’ owed by the North to the South, made by groups such as Acción Ecológica (based in Quito, Ecuador), leading to the Kyoto Protocol;
  3. Demands in 2000 (Bond 2014). According to Pulido, EJ activists are just as concerned with altering the existing power structure as they are with lowering pollution or protecting biodiversity (1996: 29–30).

environmental justice in islam

Environmental justice is a social movement that arose from the desire to ensure that all communities, regardless of color, income, origin, or race, have access to healthy environments. Below are the 17 key principles of environmental justice principles:

  1. Affirms that the environment is sacred, that everything on earth is ecologically interconnected and interdependent, and that every species has the right to be free from ecological damage.
  2. Requires that all public policies are based on justice and mutual respect for all individuals, without favoritism or prejudice.
  3. Advocates for the right to use land and renewable resources responsibly, ethically, and in a balanced manner so as to create a sustainable planet for humanity and other living organisms.
  4. Requests universal protection against indiscriminate nuclear testing, the manufacture and disposal of hazardous waste and pollutants, and the testing of nuclear material, which endanger the fundamental right to clean air, water, land, and food.
  5. Confirms every individual’s fundamental right to economic, cultural, political, and environmental autonomy.
  6. Demands an end to the production of toxic wastes and radioactive substances, and holds past and present producers accountable for the people, detoxification, and management of hazardous wastes at the point of production.
  7. Demands the right to participate as equal participants in every decision regarding their environmental surroundings, including the assessment of their requirements based on assessments.
  8. Confirms the right of every worker to a safe and healthy workplace, without having to choose between unemployment and a dangerous source of income. It also affirms that home-based workers have the right to be free from environmental hazards.
  9. Protects the rights of persons harmed by environmental injustice to receive reparations and complete compensation for their injuries, as well as excellent health care.
  10. Considers any environmental injustice perpetrated by the government to be a breach of international law; the United Nations Convention on Genocide and the Universal Declaration of Human Rights.
  11. Has to recognize a national and legal relationship between regional indigenous and the government via agreements, compacts, and treaties that affirm self-determination and sovereignty planning, implementation, and enforcement.
  12. Confirms the necessity for urban and rural ecological strategies to clear and reconstruct urban and rural areas so that they are in harmony with Nature while preserving and honoring the cultural integrity of communities and ensuring fair access to all available resources.
  13. Calls for the enforcement of the principles of informed consent and an end to the testing and experimentation of medical and reproductive procedures, goods, and vaccines on individuals of color.
  14. Argues against the damaging actions conducted by big corporations.
  15. Disapproves of the military’s occupation, exploitation, and suppression of land, people, and their many cultures and various forms of life.
  16. Calls for the empowerment of present and future generations to address social and environmental concerns based on current experience and an awareness of diverse cultural viewpoints.
  17. Requires that we make personal and consumer decisions to utilize as little of the earth’s resources as possible and generate as little trash as possible. In order to ensure a healthy world for future generations, we must make the decision to reprioritize and challenge our way of life.

Recommendations

1. Recognize climate change victims

We need to recognize that climate change has victims and give them a day in court. The research recommends that states develop a “model statute on legal remedies for climate change” that can provide access to people directly impacted by climate change. This mostly involves the clarification of procedural regulations. The IBA has already begun writing a model statute of this type as the next stage.

2. Strengthen human rights

For a very long time, it has been evident that climate change threatens human rights. Less obvious has been whether or not courts can apply current law and legal precedent to these offenses. After all, the law was written without the enormity and urgency of climate change in view. However, similar to other violations of human rights, climate change has agents, victims, and injuries. It does not require much legal imagination to make the causal relationship. Politicians, attorneys, and the international community can assist by establishing the connection.

3. Hold businesses accountable

At present, multinational firms can evade carbon accountability in much the same way that they have historically escaped responsibility for human rights crimes caused by subsidiaries and suppliers abroad. As with human rights, simple due diligence is required. The objective must be to ensure that carbon emissions are counted along the whole worldwide supply chain, from sourcing through production, distribution, and retail.
