Food Security Strategy in Qatar

Qatar is a water-scarce and arid region which has its own share of demographic and socio-economic problems. The cultivation of food crops is a difficult proposition for Qatar due to scarcity of water supply and limited availability of arable land. The country is vulnerable to fluctuations in international commodity markets because of dependence on imported cereals and food items. The increasing dependence on foreign food imports is leading to a growing sense of food insecurity in the country.

What is Food Security?

Food security is the condition in which all people at all times have a physical and economic access to safe, adequate and nutritious food to satisfy their daily calorific intake and allow them to lead an active and healthy life. Individuals who are food secure have an access to a sufficient quantity of food and do not live in fear of hunger and starvation. On the other hand, food insecurity exists simultaneously and inhibits certain groups of individuals from gaining access to nutritionally adequate and safe food. In the case of Middle East and North Africa (MENA) countries, food insecurity is related to poor quality diets rather than calorie-deficient diets. A typical diet in MENA region is high in saturated fats, sugar and refined foods which is a major cause for increase in chronic diseases in the region.

There are a multitude of factors which may challenge a nation from achieving food security. Some of these factors include the global water crisis and water deficits which spur heavy grain imports in smaller countries ultimately leading to cutbacks in grain harvests. Similarly, intensive agriculture and farming drastically influence soil fertility and cause a decline in crop yield. Another notable factor limiting food security includes the adverse effects of climate change such as droughts and floods which greatly affect the agricultural sector.

The impacts of declining crop yields will include a change in productivity, livelihood patterns as well as economic losses due to declining exports. According to the Global Food Security Index, countries which are on top of the food security index include USA, Norway and China. The countries suffering from greatest food insecurity include, Democratic Republic of Congo, Togo and Chad.

Food Security Strategy in Qatar

Being one of the fastest growing economies in the world, Qatar is facing large-scale influx of expatriate workers which has resulted in tremendous increase in population in recent years. Limited land availability, chronic water scarcity and constraints in agricultural growth have led to growing concerns about food security. Agriculture plays a strategic role in the nation’s food security. Qatar imports over 90% of its food requirements due to the scarcity of irrigation water, poor quality soils and the inhibitions due to climatic conditions. Infact, the country is facing an agricultural trade deficit of QR. 4.38 billion equivalent to $1.2 billion.

In response, Qatar has begun to address the situation by aiming to efficiently utilize ‘cutting edge technology’ to establish a sustainable approach to food security for dry land countries. The Qatar National Food Security Program (QNFSP) was established in 2008 and aims to reduce Qatar’s reliance on food imports through self sufficiency. The program will not only develop recommendations for Food Security policy but intends to join with international organizations and other NGOs to develop practices to utilize resources efficiently within the agricultural sector.

Qatar has established a nation-led National Food Security Program to encourage domestic production which will lead to scientific and technological development in two specific areas to increase domestic production. These areas include development in agricultural enhancement and food processing. QNFSP’s approach to expanding the agricultural sector aims to introduce the best practices and establishing a sector which considers its economic efficiency, optimal usage of scarce resources with limited impact on the environment as well as profitable and sustainable agriculture.

A key element of this approach will include the deployment of advanced crop production technologies and advanced irrigation systems. The QNFSP will require well managed stakeholder participation, revised agricultural possibilities and of course a comprehensive strategy for agricultural research.

The nation’s second approach to increase domestic production includes regulations and implementations on food processing. Food processing increases the shelf-life of food, reduces raw food losses and enables the continuity of product availability. By enhancing the shelf-life of food and reducing the amount of food being wasted improves a nation’s food security. The QNFSP aims to develop the nation’s food processing industry by taking advantage of the new industry being established in Qatar which will allow the country to sell its own processed goods on the global market. To meet this objective the nation will need to implement international quality assurance mechanism to be capable of producing high quality products as well as to expand their food reserves and storage facilities.

Sahara Forest Project

In addition to the trenchant efforts being made by the Qatar National Food Security Program, an interesting and promising pilot project named Sahara Forest Project is being rigorously pursued in Qatar. The Sahara Forest Project allows for sustainable production of food, water and energy while revegetating and storing carbon in arid areas.

A one hectare site outside Doha, Qatar, hosts the Sahara Forest Project Pilot Plant. It contains a unique combination of promising environmental technologies carefully integrated in a system to maximize beneficial synergies. A cornerstone of the pilot is greenhouses utilizing seawater to provide cool and humid growing conditions for vegetables, The greenhouses themselves produce freshwater and are coupled with Qatar’s first Concentrated Solar Power plant with a thermal desalination unit.

An important part of the pilot is to demonstrate the potential for cultivating desert land and making it green. Outdoor vertical evaporators will create sheltered and humid environments for cultivation of plants. There are ponds for salt production and facilities for experimentation with cultivation of salt tolerant plants, halophytes. Additionally, the facility also contains a state of the art system for cultivation of algae.

إدارة المخلفات الطبية في دول الشرق الأوسط

قطاع الرعاية الصحية في منطقة الشرق الأوسط ينمو بوتيرة سريعة جدا، الأمر الذي أدى بدوره إلى زيادة هائلة في كمية النفايات الطبية في المستشفيات والعيادات والمؤسسات الأخرى. وفقا للتقرير الصادر من وزارةا لشئون البيئة المصرية، مصر انتجت 28,300 طن من النفايات الطبية الخطرة في عام 2010. وفي منطقة الخليج، يتم انتاج أكثر من 150 طن من النفايات الطبية والمملكة العربية السعودية وحدها تنتج نصف هذة الكمية تقريبا. هذه الأرقام تدل على حجم المشكلة التي تواجهها السلطات البلدية في التعامل مع مشكلة التخلص من النفايات الطبية في جميع أنحاء منطقة الشرق الأوسط.

حجم المشكلة

الكمية المتزايدة من النفايات الطبية زادة من التحديات البيئية والصحية في المدن الرئيسية في المنطقة. وتفاقم الوضع لعدة أسباب منها استخدام طرق غير لائقة للتخلص من هذا النوع من النفايات، قلة في التكنولوجيا المستخدمة، وعدم وجود أبحاث في مجال إدارة النفايات الطبية. الإدارة غير السليمة للنفايات الطبية من المستشفيات والعيادات وغيرها من المرافق في منطقة الشرق الأوسط تؤدي لزيادة المخاطر في الصحة المهنية والعامة للمرضى والعاملين في القطاعات الصحية وإدارة النفايات الطبية وناقليها وعامة الناس. حتي انها قد تؤدي أيضا إلى تلوث الهواء والماء والتربة والتي قد تؤثر على جميع أشكال الحياة. والأهم من ذلك، إذا لم يتم التخلص من النفايات بشكل صحيح، قد تٌجمع المعدات الطبية (وخاصة الحقن) من قبل العابثين بالمخلفات وإعادة بيعها والذي قد يسبب في كثير من الأمراض الخطيرة.

طرق إدارة النفايات الطبية في منطقة الشرق الأوسط تقتصر على الحرق على نطاق صغير أو الدفن. ممارسة دفن النفايات الطبية هي مصدر قلق بالغ لأنه تشكل مخاطر كبيرة على الصحة العامة والموارد المائية وخصوبة التربة وكذلك جودة الهواء. في العديد من دول الشرق الأوسط وشمال أفريقيا، يتم خلط النفايات الطبية مع النفايات البلدية الصلبة و / أو النفايات الصناعية التي تحول النفايات الطبية إلى مزيج من المواد الخطرة.

سياسة “من” المطروحة عام 2004 في تفاقية استكهولم، شددت على ضرورة النظر في المخاطر المرتبطة بحرق نفايات الرعاية الصحية لأنها تنتج كثير من الملوثات التي قد تشمل الجسيمات الصغيرة، والمعادن الثقيلة، والغازات الحمضية، أول أكسيد الكربون والمركبات العضوية. في بعض الأحيان الجراثيم قد توجد في المخلفات الصلبة وعوادم المحارق السيئة التصميم والمدارة بشكل سيء. وبالإضافة إلى ذلك، المركبات العضوية القابلة للترشح، مثل الديوكسين ، وعادة ما تكون موجودة في بقايا الرماد السفلي. 
ونظرا لهذه العوامل، فإن العديد من البلدان الصناعية تتخلص تدريجيا من محارق الأدوات الطبية لاستكشاف التقنيات التي لا تنتج أي ديوكسين. ودول مثل الولايات المتحدة وايرلندا والبرتغال وكندا وألمانيا اغلقت بشكل كامل أو وضعت حظر على محارق النفايات الطبية
.

التقنيات الواعدة
التقنيات البديلة لمعالجة النفايات الطبية هي التعقيم بالبخار والتعقيم بالبخار المتقدم، والعلاج بالموجات الدقيقة(الميكرويف)، التعقيم الحراري الجاف، والتحلل القلوية، والمعالجة البيولوجية. في الوقت الحاضر، التعقيم بالبخار هو أسلوب العلاج البديل الأكثر شيوعا. أجهزة التعقيم المتقدمة أو تقنيات معالجة البخار المتقدمة تجمع بين التعقيم بالبخار مع الشفط، والخلط الداخلي أو الجزئي، التقطيع الداخلي، والتجفيف، والضغط مما يؤدي إلى تقليص الحجم الى 90٪..

العلاج الموجات الدقيقة هي تقنية واعدة حيث يكن ذلك عن طريق إدخال الحرارة الرطبة والبخار الناتج عن طاقة الميكروويف. العلاج القلوية هو عملية كيميائية فريدة حيث انها تستخدم مادة قلويه حارة لهضم الانسجة البشرية، والنفايات الجرثومية وقطع التشريح، العمليات البيولوجية المستخدمة في صناعة السماد يمكن أيضا أن تٌستخدم للتخلص من المواد العضوية في النفايات الطبية مثل مخلفات المشيمة.

5 Tips For Making Your Business Operations Sustainable

The Earth’s condition is getting much worse than in previous decades; weather patterns are changing, temperatures are rising, the ozone layer is depleting, and polar ice caps are melting. Thus, the call for sustainable operations has become a high-level priority for many businesses.

Implementing sustainability in business operations offers many benefits. Aside from having a good conscience from observing environmentally-friendly practices, many people may also appreciate the goodness you’re spreading by producing long-lasting, eco-friendly, and recyclable goods. They’ll support your business, purchase your products, and help your brand grow.

How to Make Your Business Operations Sustainable

On top of that, going sustainable also helps you minimize your carbon footprint, electricity consumption, and water usage. And with this, you’ll be able to save a significant amount of money that you can use for more essential business processes to reach your goals in no time.

To help you get started in transforming and making your business operations more sustainable and eco-friendlier, below are some tips and tricks you can consider:

1. Use Environmental Health Software

In today’s digital landscape, there’s a software application for almost everything you need, including an app that can help you grow your business sustainably.

An environmental health safety software, for instance. It’s an application designed to help organizations comply effectively with different rules and regulations for a sustainable operation. It’s cost-efficient, generally easy to set up, and has 24/7 customer support in case there are problems while using it.

Here are some important features you can use:

  • Measuring Sustainability: This feature allows you to check how sustainable your business is based on different key performance indicators. It provides insight that allows you to track your progress and identify unsustainable potholes in your system.
  • Industrial Hygiene Management: This feature focuses on preventing potential hazards that can put your employees at risk and mitigating them for a safe and healthy workplace.
  • Environmental Management: This feature can help you monitor water usage and waste production. Also, it can keep you on track with your sustainability metrics and ensure that you comply with different requirements.

Furthermore, the software is mobile-friendly. You can check the status of your program to see if you’re on top of your goals wherever you are.

2. Check Your HVAC Units

Are you having problems with your energy consumption? Does your bill increase constantly every month? If this is the case, you might want to checkup your heating, ventilation, and air conditioning (HVAC) units. They might be the reason for your overwhelming electrical charges.

The first thing to do is evaluate the age of your HVAC system. If it’s been there with you for more than 15 years, it’d be best to replace it with a new one. Old HVAC units are known to consume more energy than new ones. Higher energy consumption means less sustainable operations.

hvac-air-filter

Also, new HVAC models require less energy to operate. On top of that, they’re more efficient and quieter than the older models. So, don’t hesitate to replace your decade-old HVAC systems to achieve a more sustainable business environment.

3. Improve Your Lighting

Another simple trick to help reduce your energy consumption is to replace your light bulbs with newer and energy-efficient LED (light-emitting diode) types. Compared to traditional incandescent and fluorescent light bulbs, these light sources may help you significantly save energy.

While LED light bulbs are generally more expensive than non-LED types, they can help you save more in the long run. And with that, they’re still the better option when it comes to lighting fixtures.

On top of that, LED light bulbs also have a longer shelf life of up to ten years, based on normal usage. Therefore, switching to LED light bulbs may not only save you from costly energy consumption but also on maintenance fees.

4. Reduce Water Consumption

Water is an important resource for everyday use. However, the water supply across the world continues to become scarce. That’s why it’s crucial to do your part in saving water and reducing water waste in all aspects of your business operations.

water-conservation-middle-east

Also, don’t forget to conduct different audits and routine checkups to determine any leakages under your pipelines. Check all the facilities where water runs, including toilet rooms and faucets. This can help you prevent wasting water unnecessarily and the drastic increase in your water bills.

Furthermore, if you have extra funds, you may build a small water treatment facility to treat and reuse wastewater and help the world preserve its natural water resources.

5. Go Paperless

Perhaps, this tip is one of the simplest and easiest ways to make your business operations sustainable. By implementing a paperless approach in the workplace, you can significantly help trim down paper usage and the need to purchase additional stacks of papers for business needs.

This tip is relatively easy, considering how most businesses are now shifting to digital platforms such as using email for faxing in the cloud when conducting transactions and sharing documents. Digitize billing, too: if your team already works in spreadsheets, try Excel for invoicing to access free, customizable invoice templates that auto-calculate totals and export to PDF, reducing printing, paper use, and filing waste. You can also encourage your team members to skip printing documents for signatures, especially since there are various e-signature applications available today.

Final Words

Sustainable business operations are a top priority for most businesses. These allow them to save more on expenses and billings and help preserve the environment.

As a good starting point, you may embrace and implement the tips discussed above- conduct regular audits and check to identify potential problems in your HVAC system, upgrade your light bulbs into LEDs, reduce water consumption, and switch to paperless business transactions. Furthermore, use the environmental health safety software to help you keep track of your status regarding your sustainable practices and improve what needs to be improved.

Everything You Should Know About Carbon Footprint

With rising awareness of global warming and effects of emissions on the environment, corporates and individuals alike are rising to tackle environmental issues. Carbon footprint, the first step to reduce carbon emissions, is the total set of GHG emissions caused directly or indirectly by an individual, organization, event or product.

The main reason for calculating a carbon footprint is to inform decisions on how to reduce the climate change impact of a company, service or product. Carbon footprints are measured by undertaking a greenhouse gas assessment. Once the size of a carbon footprint is known, a strategy can be devised to reduce it.

carbon footprint

Why Carbon Footprint?

Growing public awareness about climate change and global warming has resulted in an increasing interest in ‘carbon footprinting’. The global community now recognizes the need to reduce greenhouse gas emissions to mitigate climate change.

The most popular methods to reduce carbon footprint include use of alternative energy, reforestation, waste reduction and energy efficiency. Population, economic output, primary energy mix and carbon intensity are the major parameters in determining the carbon footprint of a particular country.

Carbon footprint is the foremost indicator of environmental responsibility and helps to identify climate impacts and lower them cost-effectively by strategic and operative planning, constructing a climate policy, environmental reporting etc. In addition, carbon footprint promotes positive, environmentally conscious company image and can boost the marketing of an organization and its products.

What are Different Types of Carbon Footprint

There are different types of carbon footprint, e.g. for organisations, individuals, products, services, and events. Different types of carbon footprint have different methods and boundaries. The various approaches and types of greenhouse gas assessment are discussed below.

1. Product Carbon Footprint

Product Carbon Footprint is suited for organizations which have distinct products and services. It delivers a view of GHG emissions specific to a single product or service. This can then be scaled up to the entire organization. Product Carbon Footprint can be assessed to capture either business-to-business view (cradle-to-gate) or business-to-consumer view (cradle-to-grave).

2. Corporate Carbon Footprint

Corporate Carbon Footprint is suited for organisations wishing to take an overview of the carbon footprint of the entire organization. The process starts off by identifying the business goals for the GHG inventory, setting up suitable organizational boundaries, selecting an appropriate baseline period; data collection and finally preparing plan for data quality management.

3. Valye-Chain Carbon Footprint

Value-Chain Carbon Footprint includes activities associated with the product or services of an organization over entire value chain.  This accounts for emissions arising from raw material procurement to the end of product life. Value-chain carbon footprint provides an aggregate view of all the products and services of the company.

Carbon Footprint in the Middle East

The world’s dependence on Middle East energy resources has caused the region to have some of the largest carbon footprints per capita worldwide. Oil and gas industry, electricity production, transportation, industrial heating and air-conditioning are responsible for most of the carbon emissions from the region. Qatar, Kuwait, UAE, Bahrain and Saudi Arabia figure among the world’s top-10 per capita carbon emitters. Infact, carbon emissions from Qatar are approximately 38.62 tons per capita, which is more than double the US per capita footprint of 13.8 tons per year.

Jordan’s Solar Surge: Policy Shifts and Tech Innovations Fuel Distributed PV Growth

Jordan’s renewable energy sector underwent significant transformation in 2024. The Ministry of Energy and Mineral Resources (MEMR) introduced the updated Renewable Energy and Energy Efficiency Law (12) of 2024, followed by Bylaw (58) of 2024. Effective September 2024, prosumers in Jordan can now choose from four on-grid solar PV connection mechanisms:

  1. Wheeling (off-site solar PV systems)
  2. Net Billing
  3. Zero to Grid
  4. Buy-All / Sell-All

The bylaw imposes a “Grid Fee” on all mechanisms except Buy-All / Sell-All, with varying rates for different consumer types. Additionally, it set the annual specific electricity production from solar PV at 1,800 kWh/kWp/year and fixed the DC:AC ratio at 1.5 for residential and 1.2 for other sectors. Residential solar PV systems are now capped at 5.4 kWp for single-phase meters and 15 kWp for three-phase meters.

Electricity Tariffs for Residential Sector

The electricity tariffs for the residential sector in Jordan were changed starting 1st of April 2022, and it was divided into two categories; Supported and Un-supported as shown in Figure 1 below.

electricity tariff in jordan

 

Figure 1. Electricity Tariffs for the Residential Sector in Jordan starting 1st April 2022

Each Jordanian family can apply to have one electricity meter with supported electricity tariffs. The supported step-up tariffs have three tiers as follows:

  • (1 – 300 KWh) pay $0.0705 USD/KWh
  • (301 – 600 KWh) pay $0.141 USD/KWh
  • (Above 600 KWh) pay $0.282 USD/KWh

Unsupported step-up two-tier electricity tariffs are applied to additional meters that Jordanian families have, and are also applied to non-Jordanians. Following are the unsupported two step tariffs:

  • (1 – 1,000 KWh) pay $0.1693 USD/KWh
  • (Above 1,000 KWh) pay $0.2116 USD/KWh

Dynamic Tariffs and Time-of-Use (ToU) Pricing

On July 1, 2024, Jordan introduced dynamic electricity tariffs for six sectors. Dynamic tariffs expanded into twelve sectors by January 2025, and are expected to cover all sectors by end of 2025.The Time-of-Use (ToU) tariffs divides consumption into three periods as follows:

  1. Off-Peak (5 AM–5 PM) – Lowest rates to align with peak solar generation.
  2. Peak (5 PM–11 PM) – Higher rates as demand shifts to thermal power.
  3. Partial Peak (11 PM–5 AM) – Moderate rates during lower nighttime demand with no generation from the solar PV.

This structure incentivizes daytime electricity use when solar generation is abundant while reflecting higher costs for evening thermal power reliance.

Residential Solar PV Options

The previously available Net Metering scheme has been discontinued with the issue of Bylaw (58) of year 2024. Since September 2024, new residential prosumers have three connection mechanisms available for them to choose from:

  • Net Billing: Excess monthly daytime generation is purchased by the electricity distribution companies at $0.0705/kWh during each ToU period and pay the residential sector monthly grid fee. Residential sector prosumers under the supported electricity tariffs consuming above 600 KWh/month in any period pay ($0.282/kWh), making battery storage increasingly attractive.
  • Zero-to-Grid: Prosumers cannot export to the grid and must size their PV systems strictly for daytime use. In addition, the prosumer pays the residential monthly grid fee.
  • Buy-All /Sell-All: A separate electricity meter is installed at this facility and all generated electricity from the solar PV system is sold to the grid at $0.0705/kWh (residential) and at $0.0564/kWh for all other sectors.

Growth in Distributed Solar PV

By the end of 2024, Jordan’s three electricity distribution companies reported 1,196 MWAC total installed capacity with 82,780 systems across all sectors as shown in Figure 2 below:

installed solar capacity in jordan

 

Figure 2. Total installed solar PV capacity on distribution grids in Jordan by end 2024

Breakdown by provider:

  • JEPCO: 35,176 systems (658.176 MWAC)
  • IDECO: 32,480 systems (333.500 MWAC)
  • EDCO: 15,124 systems (204.700 MWAC)

Assuming an average overall DC:AC ratio for all systems on the distribution grids of 1.2 and annual production of 1.56 GWh/MWP, these systems generated an estimated 2,240 GWh in 2024 equivalent to 9% of Jordan’s total electricity sales (22,323 GWh) as reported by the National Electric Power Company (NEPCO) on their website.

Utility-Scale Solar Expansion

The 1 MWAC cap on solar projects, imposed in 2019, was lifted in September 2024, spurring large-scale developments. In April 2025, MEMR announced a 200 MWAC solar tender under a Build-Own-Operate (BOO) model, signaling renewed investment in utility-scale renewables.

Technological Advancements

Key innovations driving adoption include:

  • According to the International Energy Agency (IEA), battery costs have dropped more than 75% between 2015 – 2024. This is enabling the local prosumers to use the storage technologies to offset peak electricity tariffs.
  • Higher-efficiency solar modules, including TOPCon (Tunnel Oxide Passivated Contact) advanced solar cell technology that can be combined with 0BB design, which reduces shading losses by up to 70%.
  • PV modules have achieved low degradation rates of 0.35% per year after the first year.
  • Amid rising global occurrences of severe weather events—including the hailstorm that struck Amman, Jordan, in May 2023, damaging solar PV modules in the Shafa’a Badran area—Philadelphia Solar successfully launched its 55mm anti-hail PV module. Specifically engineered to endure extreme weather conditions, the module has undergone and passed rigorous IEC certification testing for hail impact, demonstrating resilience against hailstones with diameters of up to 55mm.
  • LONGi, a leading manufacturer of PV modules, announced at Intersolar Munich in May 2025 the commencement of mass production of 54-cell transparent bifacial modules with a maximum efficiency of 25.0% backed by a 30-year power and material warranty.

Renewables’ Share in the Energy Mix

While official data for 2024 remains pending, renewables are projected to maintain a share of approximately 27% of electricity generation, despite rising demand driven by the electrification of heating, cooling, and electric vehicles (EVs).

solar panel maintenance

Jordan’s solar sector is poised for continued growth, supported by progressive regulatory policies, cost-effective technological advancements, an increase in global production expected to grow from 600 GW in 2024 to reach 1 terawatt per year (1 TW/year) by 2030, and a growing shift toward decentralized energy generation.

Share of renewables from the overall electricity generated

The 2024 share of electricity generated from renewable energy sources has not been announced by NEPCO or MEMR as of the time of writing this article. With the continuous growth of electricity consumption due to electrification of heating, increase in cooling loads, and increase in EV adoption, it is expected that the percentage of will remain the same around 27%.

Jordan’s solar PV advancements offer a compelling model for Middle Eastern nations facing energy and climate challenges. By embracing progressive policies like dynamic tariffs and decentralized solar with several connection mechanisms, Jordan demonstrates how countries can enhance energy security and reduce emissions. Its success highlights the potential for regional climate resilience through renewable innovation, inspiring countries developing their renewable energy regulatory frameworks to adopt similar strategies.

Jordan proves that even resource-limited nations can lead in the global shift toward clean energy, setting an example for a sustainable, decentralized future in the region.

Why You Should Be Drinking More Water

The need to be well hydrated, i.e. drinking fluids throughout the day is critical with some very real benefits for each and every one of us. The bottom line is drink more water, stay hydrated, and read on to realise the benefits of this simple task.

Of course, depending on the season and where you live, will alter the recommended daily intake of water. Just as age will modify demands, so will the level of exercise, nature of your activities, affect the water demands.

drinking water

Regardless of age, we all want to look beautiful or handsome. Drinking water helps us to achieve this goal by ensuring our skin retains moisture. This means that water intake will increase the elasticity of our skin and minimise the appearance of wrinkles. Not only will our skin look better overall, it will also help flush toxins out of our body which can alter our complexion. Facial pores will be minimized and your body should be cleared of acne.

As well as improving your outward appearance, being well hydrated works wonders inside your body as well. Let’s consider your blood pressure. Your blood is about 90% water. Therefore, there is a big need to be well hydrated. Less water intake, means less water in your blood stream meaning your blood stream will be thicker and in turn, will increase your blood pressure. Raised blood pressure can cause life threatening conditions, so go drink some more fluids.

For those of us who work with tools or machinery, yes even a sewing machine, we understand the principle of lubrication. Likewise, our body needs to be well hydrated so as to lubricate our joints. By drinking water, we maintain our body cartilage. This is the connective tissue that covers and protects the ends of our bones and the entire joint structures. If we fail to stay hydrated, there will be a breakdown or reduction in our cartilage. This in turn will result in extreme pain and possible damage to our joints.

So you can see there are many health benefits of drinking water. But there are still more reasons to be hydrated that might receive as much attention. If you are working more strenuously or undertaking a more rigorous workout in the gym, you need more fluids to help boost your performance, and help you maintain the higher level of activity.  Simply drink more water.

Even your brain is a mass of fluid – 80% water. So, it’s a no-brainer, drink more water so your mind is better able to function more efficiently and effectively. That sounds like a smart thing to do because your will benefit by being smarter all round. There are more pluses. Your concentration will certainly improve along with your cognitive ability. Your mood and emotions will benefit by being better balanced. And wait for it, you will maintain better memory function with a well hydrated brain.

Now I am not encouraging you to drink more water to increase your saliva level for less desirable behaviour, but we all need saliva to help with digesting our food. Good saliva also helps maintain oral hygiene. Without a healthy and fresh saliva, we might create oral problems that cause other health issues. Keep drinking that extra glass of water.

When you come inside after a tough workout, a long run in the sunshine, or a hard work session in the garden, yes, we opt for a shower to wash down and cool off. But drinking water—or reaching for effective hydration drinks—is always the first port of call to cool the body down. This is the most natural and quickest way to bring our body temperature down.

Remember, that if we are sweating, or should I say perspiring, we are losing water from our body through the surface of our skin. Water loss means we need to replenish out water intake. Yes, it is helping us to allow our body to cool down but we must keep a good balance between water loss and water replacement.

Can there be any other benefits from drinking water you wonder? Yes, there are. Before your sit down to a big meal, drink a small or medium glass of water. That is enough to make your stomach a little fuller before your start eating. But there enough fluid to cause you to feel fuller sooner, and perhaps eat less. And always drink water, more readily than commercially made fruit juices or soda drinks. Those are rich in calories while water has no calories. So, you can drink all you like.

home water filtration

Your digestive system also requires water for a healthy digestive system. Stay hydrated to avoid digestive problems or even constipation. A healthy fluid intake will also help balance stomach acids and minimize irritation in that region. Remember, minerals and nutrients need to be dissolved in water to be accessible within and throughout your body. Otherwise, the goodness contained will not be accessible within the body.

Dehydration can also mean less body fluid overall. This could be realised with very dry airways. This in turn could aggravate symptoms associated with allergies or breathing conditions. Also in the upper torso, headaches can arise. Being well hydrated can also be a way to better manage and control headache occurrence.

Why Giving Up Meat Is Essential To Mitigate Climate Change

Meat consumption is a staple of the modern diet. In the developed world, meat consumption has been rising consistently for decades. In the developing world, people eat less meat as they cannot afford the high cost of it. The scale of global meat consumption has grave environmental effects and intensifies Climate Change. This is as, “the global production of food is responsible for a third of all planet-heating gases emitted by human activity” [1]. Therefore, it is reasonable to argue that the connection between meat consumption and the negative effects of Climate Change like global warming is something which needs to be explored in depth so we can understand how to reduce the risk of environmental catastrophe.

how giving up meat can reduce climate change impacts

Moreover, giving up meat plays an essential role in reducing the effects of Climate Change. The norm of meat consumption is environmentally unsustainable as, “cows, sheep and goats…still need lots of land for grazing” which could instead be used for planting more trees to absorb the high levels of carbon dioxide in the atmosphere, a project which is crucial to curbing the effects of Climate Change [2]. In addition, “the carbon footprint of beef and lamb is roughly three times higher than that of pork, poultry or farmed fish per 100g of protein, and 24 times higher than pulses such as beans and lentils” [2]. This links with the disastrous impact of cattle farming on the environment.

Cattle farming causes natural habitat loss as more land must be cleared and deforested while carbon emissions keep increasing [2]. On a practical level, the campaign to reduce global meat consumption and save the planet is reinforced by the fact that beef production is associated with the loss of tropical forest cover in the Amazon rainforest [2].

Therefore, giving up meat is an important step from a moral perspective especially because of the effects of Climate Change. A meat-free lifestyle puts less strain on the environment as it significantly reduces the risk of deforestation and rising carbon emissions due to reduced demand for meat production. As a result, I believe giving up meat is crucial to reducing your carbon footprint and staying proactive in mitigating the effects of Climate Change.

Another reason why giving up meat is important in reducing the effects of Climate Change is because red meat is a key source of methane emissions. Methane, a greenhouse gas, is 23 more warming than carbon dioxide and directly contributes towards global warming, one of the significant repercussions of Climate Change [3]. A further consequence of meat consumption is livestock manure which is responsible for 65 percent of nitrous oxide emissions [3]. Nitrous oxide, another greenhouse gas, stays in the atmosphere for 114 years [4]. Nitrous oxide contributes to Climate Change by remaining in the ozone layer and causing global warming [4].

From a consumer perspective, I recommend reducing meat consumption or opting for a meat-free diet as emissions of Methane and Nitrous Oxide will fall and this helps will lower the global risk of global warming and alleviate impacts of Climate Change.  My opinion can be backed up by evidence. For instance, “three of the world’s largest meat producers, JBS, Cargill, and Tyson, emitted nearly as many greenhouse gases as the biggest oil companies, including Exxon, BP, and Shell” [5].

Furthermore, giving up meat is crucial in reducing the effects of Climate Change as wasted meat ends up in landfill sites and releases large amounts of Methane, a greenhouse gas. For instance, “we waste an estimated 1.3 billion tonnes of food every year” and wasted meat leads to increased Methane emissions [6]. In turn, these emissions of Methane cause the percentage of greenhouse gases in the atmosphere to rise leading to global warming and exacerbating the effects of Climate Change. As both livestock manure and wasted meat deposited at landfill sites release Methane into the atmosphere, the risk to the environment is undeniable. So, another good reason to give up meat is to reduce air pollution caused by high levels of methane in the atmosphere.

food-waste

The environmental benefits caused by adopting a meat-free diet include less air pollution caused by landfill sites. In my opinion, this is a fantastic reason to opt for a meat-free diet. Not only does a meat-free diet reduce Methane emissions, but it also reduces air pollution which is responsible for millions of premature deaths every year and fueling Climate Change. As such, “to combat the climate emergency and help protect our environment, we all need to reduce the amount of food we waste” [6].

To conclude, giving up meat is essential to reducing the long-term effects of Climate Change. Meat consumption is strongly linked to environmental problems like deforestation, natural habitat loss and the emission of Methane and Nitrous oxide, all of which cause the build-up of greenhouse gases in the atmosphere and contribute to global warming. This links directly with Climate Change. Therefore, reducing your meat intake or becoming vegetarian or vegan is the first step to reducing the harmful effects of Climate Change.

التصدي لأثار التغيرات المناخية بالمغرب

يبدو أن الرجوع إلى فترة ما قبل الثورة الصناعية سيصبح شيئا حتميا لا مناص منه ان نحن أردنا أن ننقذ أنفسنا و أرضنا من عواقب الأزمات البيئية بسبب ما يسمى بالتغيرات المناخية. و لقد فطنت و تيقنت العديد من الدول إلى هذا الخطر الداهم و من بينهم المغرب الذي انخرط في مساعي الحد من التأثيرات المناخية بشكل ملحوظ رسميا و فعليا من خلال عدة مشاريع وطنية كمخططات المغرب الأخضر للنهوض بالقطاع ألفلاحي و سياسات النجاعة الطاقية كمشاريع إنتاج الطاقات المتجددة.

و قد أصبح البلد بهذا رائدا في هذا المجال عربيا و إفريقيا. و تتجسد هذه الريادة كذلك من خلال استضافة مؤتمرات دولية كان آخرها مؤتمر قمة الأطراف كوب 22 . و لا يعتبر عزم المغرب على الخروج من التبعية الطاقية السبب الوحيد لإتباع سياسات النجاعة الطاقية و لكن لان المغرب كذلك مهدد بعواقب التغيرات المناخية السلبية كفترات الجفاف التي تضرب المناطق الجنوبية بالأخص مما يؤثر على محدودية المياه هناك و اجتياح الفيضانات لمناطق أخرى بسبب التساقطات المطرية و الثلجية المركزة في الزمان و المكان وصولا إلى تضرر بعض المناطق الأخرى كذلك من تسوناميات و أعاصير صغيرة كالتي ضربت الواجهة الأطلسية للمغرب في السنوات الأخيرة.

وناهيك عن الأضرار المادية و البشرية التي قد تسببها تأثيرات التغيرات المناخية فان عدم الاستقرار الاجتماعي و الأمني لبلد كالمغرب لا سمح الله به قد تؤدي عدم الاستقرار في مناطق أخرى خاصة أوروبا و كذلك الدول الإفريقية و العربية بتأثير اقل و من هنا إذن تبنى المغرب سياسة استباقية مستقبلية للتصدي للمشاكل التي قد نتعرض لها جميعا.

إن ما قد يزيد من التوجه الرسمي للدولة المغربية إزاء محاولة التصدي لتأثيرات التغيرات المناخية و ترسيخ مخططات الطاقة النظيفة و المحافظة على البيئة هو ان ينخرط الأفراد أنفسهم لكي نرى هذه الرؤى و التوجهات مجسدة في الحياة اليومية و الفردية للمواطنين , وهو شيء يظهر انه مازال بعيد المنال لأني أرى اشخصا يتعاملون مع الموارد الطبيعية كالطاقة و الماء و كأنهم من عالم أخر لم يسمعوا فيه أبدا بالمحافظة على البيئة بل و نجد هذا حتى في أماكن المفروط أن تعلم هذه القيم كالمؤسسات التعليمية و المساجد التي لطالما رأيت العديد منها يضيع الكهرباء و الماء دون أي اكتراث لا بالوازع الأخلاقي و لا الديني.

قد تجد عائلة هنا أو هناك تستعمل الآلات الالكترونية طوال اليوم كان يبقى التلفاز مثلا مشغلا اليوم كله دون أن يكون متفرج واحد أمامه ا وان تقتصد عائلة أخرى على استعمال الكهرباء ليس بسبب إحساسها البيئي و إنما فقط لتخفيض الفاتورة. و يبقى إذن التحسيس و التربية البيئيتين أمرا ملحا  و ذو أولوية مهمة للتصدي الفعلي لمخاطر التغيرات المناخية بالمغرب.

Waste-to-Energy Potential in Saudi Arabia

WastetoEnergy-SaudiArabiaThe Kingdom of Saudi Arabia has been grappling with the problem of solid waste in recent years. Around 15 million tons of municipal solid waste is generated in the country each year with per capita average of 1.4 kg per day. Depending on the population density and urban activities of that area, the major ingredients of Saudi Arabian MSW are food waste (40-51 %), paper (12-28 %), cardboard (7 %), plastics (5-17 %), glass (3-5 %), wood (2-8 %), textile (2-6 %), metals (2-8 %) etc.

Due to high population growth rate, (3.4% per annum), rapid urbanization (1.5% per annum) and fast economic development (3.5% yearly GDP rate), the generation rate of MSW is expected to reach 30 million tons per year by 2033. Waste management issues in Saudi Arabia are not only related to water, but also to land, air and the marine resources. The sustainable integrated solid waste management (ISWM) is still at the infancy level in the oil-rich kingdom

In Saudi Arabia, MSW is collected and sent to landfills or dumpsites after partial segregation and recycling. The major portion of collected waste is ends up in landfills untreated. Recycling of metals and cardboard is the main waste management practice in Saudi Arabia, which covers 10-15% of the total waste and usually carried out by the informal sector.

The landfill requirement in KSA is very high, about 28 million m3 per year. The problems of leachate, waste sludge, and methane and odor emissions are occurring in the landfills and its surrounding areas due to mostly non-sanitary or un-engineered landfills. However, in many cities the plans of new sanitary landfills are in place, or even they are being built by municipalities with capturing facilities of methane and leachate.

Waste-to-Energy provides the cost-effective and eco-friendly solutions to both energy demand and MSW disposal problems in Saudi Arabia. The choice of conversion technology depends on the type and quantity of waste (waste characterization), capital and operational cost, labor skill requirements, end-uses of products, geographical location and infrastructure.

Several waste to energy technologies such as pyrolysis, anaerobic digestion (AD), trans-esterification, fermentation, gasification, incineration, etc. have been developed. As per conservative estimates, electricity potential of 3 TWh per year can be generated, if all of the KSA food waste is utilized in biogas plants. Similarly, 1 and 1.6 TWh per year electricity can be generated if all the plastics and other mixed waste (i.e. paper, cardboard, wood, textile, leather, etc.) of KSA are processed in the pyrolysis, and refuse derived fuel (RDF) technologies respectively.

The current SWM activities of KSA require a sustainable and integrated approach with implementation of waste segregation at source, waste recycling, waste-to-energy and value-added product recovery. By 2032, Saudi government is aiming to generate about half of its energy requirements (about 72 GW) from renewable sources such as solar, nuclear, wind, geothermal and waste-to-energy systems.

How To Enjoy Luxurious Living Without Harming The Environment

They say that money cannot buy everything. However, it can buy quite a lot. It is suggested that all wealth is vanity; however, there is so much to admire about the lifestyle of the world’s billionaires and millionaires. From flying across the globe in expensive private jets, driving swanky cars, owning mansions all over the world, dining at the most luxurious hotels to wearing luxury brands; the rich people’s lifestyle is simply glamorous. It is the dream of many to afford that kind of lifestyle.

Here is an interesting fact: According to economic research, the eight richest individuals in the world control as much wealth as the bottom half of the world’s population. The amount of resources and assets they have accumulated over their lifetime can finance half of the entire world. So much are we engrossed about being super rich that we forget the impact of the rich luxurious life on the earth. On the flip side of all that glamour, luxurious living has dealt a heavy blow to our environment. The rich lifestyle is basically all about eating life on a big spoon.

However, the carbon footprint that results from extravagant living is extremely large. If everyone in the world was that rich, it means that mother nature would not be in be able to sustain the world’s population. Scientific studies have indicated that in the United States of America, the top 10% people have six times as much impact as the bottom half of the entire country’s population on the environment. That is just an indication of how the rich are enemies of mother nature. But how exactly is this possible?

Let us take a deeper look at it and see how the negative impact can be reduced.

Travel

The rich travel in private jets and own fleets of high fuel consumption vehicles. The amount of greenhouse gases such as carbon (iv) oxide emitted by such vehicles is simply too much. A private jet emits more than one hundred times as much waste carbon gas as one car.

If you come to think about it, it does not make sense for one individual to own hundreds of personal cars. They probably never even use some of them. All this does is increase the carbon footprint since a lot of natural resources are used to satisfy the demand of one individual. The worst part of it is that these resources go to waste since the individual does not fully utilize the manufactured products.

To curb this kind of wastage, the rich should embrace public means of transport. If they have to fly, they can fly first class instead of acquiring their own planes which simply contribute more to environmental degradation. It may not be that luxurious, but it does serve the purpose. There is no point of owning so many cars yet only a few are enough to suffice.

Building

The rich are obsessed about owning mansions. Which is why billionaires own dozens of houses spread across states and counties. You wouldn’t be surprised if I told you that they probably haven’t spent a single night in some of those houses. You must be wondering how building houses is harmful to the environment. Well, construction is responsible for 41% of the total energy consumption in the world today. Almost three quarters of the electricity produced globally is used to run buildings, especially homes.

If you are a rich person who is just building a mansion for prestige, you are simply wasting a lot of energy that could have been put to better use. The process of extraction of building materials from their natural state is not environmental friendly. It involves excavation that destroys scenery and manufacturing processes whose emissions negatively impact the ecosystem. You don’t really have to own house that you barely utilize at your every travel destination.

For the love of the environment, sleep in a hotel prestigious enough to carter for your needs. You don’t have to overstretch the major natural resources in the environment. If you have to construct a house, engage environmental experts who will advice you on green construction designs. For example, you may use a wooden gate, instead of a metal gate to protect your residential property.

Recreation

Most rich peoples homes are never complete without recreational amenities such as swimming pools, water porches and hot water tubs. Such amenities waste a lot of water and land. For most of them, you need a continuous flow of water in and out of the reservoir. Many rich people have no contingency on how to minimize water wastage by recycling because they simply don’t care.

Temporal water recreation facilities such as inflatable tubs are more economical and environmental friendly. According to Linton’s In The Garden, inflatable tubs are just as effective as the regular ceramic tubs but more eco-friendly. There are a few other rather absurd recreational activities that the rich take part in. A good example is game hunting. The idea of killing animals for the fun of it simply breaks my heart. It leads to decreased population of certain species and hence tipping the scales of ecological balance.

Instead of extravagant and wasteful hobbies, more sustainable alternatives—like camping in Forster or exploring natural landscapes—offer a low-impact way to enjoy nature without harming it. All this is not to turn a blind eye on the efforts some of the rich people put in positively impacting the society. It is worth acknowledging that a number of influential people have channeled funds to sponsor environmental conservation programs all over the world. This is definitely a positive gesture that should be appreciated.

All this is not to turn a blind eye on the efforts some of the rich people put in positively impacting the society. It is worth acknowledging that a number of influential people have channeled funds to sponsor environmental conservation programs all over the world. This is definitely a positive gesture that should be appreciated.

It is, however, a wake up call that such environmental conservation efforts are completely worthless if our way of life is harmful to the environment. This can be likened to robbing with one hand and donating with the other. It would also be in bad faith to insinuate that the poor and the middle class people do not contribute to the degradation of the environment. Those little acts we do whether intentionally or subconsciously such as littering also aid in pollution.

With particular attention to the rich in the society, you should know that living happily does not necessarily include extravagance. By now you probably have a picture of the adverse effects of extravagance to the environment. It is important that billionaires also adopt ways of living; such that if everyone in the world lived in that way, the planet would still sustain us.

Pump – Types, Functions and Applications

A pump is a device used to transfer fluid from one point to another. A pump is categorized as a hydraulic mechanical machine used to move fluid from a point of low pressure to point of high-pressure. In many industrial, agricultural, and municipal applications, the effective management and containment of these transferred fluids are critical, often relying on specialized systems provided by companies like Plastic Fusion Fabricators. All pumps work by creating a vacuum. This vacuum is responsible for making the pump suck the fluid into the pump so that it can be moved to the required destination.

All pumps work by creating a vacuum. This vacuum is responsible for making the pump suck the fluid into the pump so that it can be moved to the required destination. There are various types of pumps used for different types of fluids. Some pumps are meant for use in gaseous applications while others are used for liquids and others for to transfer slurry media.

How does a pump work?

A pump can be a centrifugal or positive displacement pump. All pumps use similar principle of creating a vacuum in their working principle. The pump uses a prime mover which can be an electric motor or internal combustion (IC) engine. The work of the prime mover is to provide the power needed to run the pump. The prime mover is connected to the pump via the pump inlet shaft. This shaft is responsible for transmitting the power from the prime mover to the pump.

When the pump creates a vacuum (state of lower pressure than atmospheric pressure), it makes the high atmospheric pressure force the fluid into the pump at high speed. Inside the pump, the fluid’s kinetic energy is converted into pressure energy. This pressure energy is used to move the fluid from the pump to the required destination.

Working of a pump of a displacement pump and a centrifugal pump

Types of pumps

1. Positive displacement pump

This is a type of pump that uses moving components such as pistons, plungers, lobes, rotors, and gears to drain fluid from the pump and increase fluid pressure simultaneously. This type of pump does not need to be primed since pump manufacturer design it to be self-priming.

There are various types of positive displacement pumps which include diaphragm pumps, gear pumps, progressive cavity pumps, screw pumps, piston pumps, and rotary lobe pumps among others.

piston displacement pump

Advantages of positive displacement pumps 

  • These pumps work at a very high pressure relative to centrifugal pumps.
  • They have a high volumetric efficiency of around 98%.
  • They have high power to their weight ratio.
  • They have smooth and precise motion.
  • They are flexible in performance.
  • They work very well at high fluid head.
  • They are very suitable for use in very viscous fluids.
  • They do not have cavitation problems.

Disadvantages of positive displacement pumps 

  • They make high noise levels.
  • They have low discharge capability.
  • They cannot deliver fluid free from pulsation

2. Centrifugal pumps

This is a pump that works by increasing pressure as the fluid passes through the pump. As the name suggests, this pump works by using centrifugal force. This type of pump uses components known as impellers and diffusers. The impellers rotate at high speed which creates a vacuum in the pump. It is due to this vacuum that the fluid is sucked into the pump at high speed. The diffuser is used to convert the kinetic energy of the fluid into pressure energy.

There are several types of centrifugal pumps which include radial flow pumps, horizontal centrifugal pumps, vertical centrifugal pumps, submersible centrifugal pumps, axial flow pumps, and mixed flow pumps among others.

centrifugal pump

Advantages of centrifugal pumps 

  • These pumps are versatile since they can be used in different applications.
  • These pumps are efficient in terms of energy usage.
  • They need low maintenance.
  • They are of different sizes from small, and medium to large sized pumps.
  • They are resistant to corrosion.
  • They have smooth fluid flow.
  • Centrifugal pumps need smaller space for installation relative to displacement pumps.

Disadvantages of centrifugal pumps 

  • These pumps require priming.
  • They do not work well at high fluid heads.
  • They are not suitable for use in very viscous fluids.
  • They are prone to cavitation.
