CDM Enhancing Africa’s Profile Among Investors

The Clean Development Mechanism (CDM) is an extremely simple concept. Companies in developed economies can continue with their polluting ways so long as they pay for reductions in greenhouse gas emissions elsewhere in the world. Substitute Egypt, Libya, Sudan, Zimbabwe and a string of other African countries for 'elsewhere'.

CDM may not figure highly on the financial radar screens of many entrepreneurs and business people across the globe. They're probably much more exercised over the merits or otherwise of business banking services, But maybe they should be looking at CDM, not least because entrepreneurial activity and green make interesting bedfellows these days.

The rationale behind CDM is a fascinating one. It's predicated on the belief that it's far harder and costlier for industrialized countries to reduce greenhouse gas emissions than developing countries. That's because developing countries usually start from a less-cluttered and less-regulated historical background. However, projects demonstrating reduced greenhouse gas emissions must also meet sustainable development and additionality criteria in order to qualifying for CDM support.

Put simply, this means any project or venture must clearly show that the use of resources not only meets human needs but also doesn't harm the environment at the same time. And any greenhouse gas reductions made as a consequence would have happened anyway, with or without CDM funding. The international treaty, the United Nations Framework Convention on Climate Change (UNFCCC), was the forerunner to the legally binding Kyoto Protocol, adopted by almost all countries of the world.

Under Kyoto, the most highly industrialized countries are required to achieve quantifiable reductions in greenhouse gas emissions. Less-developed countries, which are much more likely to suffer disproportionately from the effects of any climate change, don't have such targets. According to the UNFCCC secretariat, the CDM and other market-based mechanisms, adopted as part of the Kyoto Protocol negotiations, allows emission-reduction projects in developing countries to earn certified emission reduction (CER) credits, each equivalent to one tonne of CO2. These CERs can be traded and sold, and used by industrialized countries to meet a part of their emission reduction targets under the Kyoto Protocol.

The mechanism, says the UNFCCC secretariat, stimulates sustainable development and emission reductions, while giving industrialized countries some flexibility in how they meet their emission reduction limitation targets. The UNFCCC announced at the beginning of February 2013 the number of CDM projects registered had reached the 6,000 mark. Last week, the UNFCCC secretariat and the East African Development Bank (EADB) signed a partnership agreement to establish a regional collaboration centre in Kampala, Uganda, in an effort to increase participation in CDM projects.

It is the second such centre in Africa, the first one being opened several months ago in Lomé, Togo, by the UNFCCC in collaboration with the BanqueOuestAfricaine de Développement. UNFCCC Executive Secretary, Christiana Figueres, said, “The two regional collaboration centres in Lomé and Kampala are designed to help Africa increase its attractiveness and potential for CDM. Our goal is to build capacity, reduce the risk for investors in such projects and help make the continent an increasingly attractive destination for CDM projects.”

The office in Kampala will be operational from May 2013. Besides hosting the office, the EADB is also expected to provide personnel, as well as administrative and logistical support. EADB Director General Vivienne Yeda lauded the partnership between the two organizations and said, “This partnership with UNFCCC is key for us at EADB as we invest in sustainable development and seek to ensure sustainability in all our operations. We hope that the new office will help increase the regional distribution of CDM projects in East Africa where there is an acute need for sustainable development.”

The Kampala office is expected to enhance capacity-building and provide hands-on support to governments, non-governmental organizations and businesses interested in developing CDM projects in more than 20 countries in the region. Among the countries that can seek support from the new office are Egypt, Kenya, Uganda, Tanzania, Rwanda, Burundi, Angola, Botswana, Comoros, Equatorial Guinea, Eritrea, Ethiopia, Lesotho, Libya, Malawi, Mauritius, Mozambique, Namibia, Seychelles, South Africa, Sudan, Swaziland, Zambia and Zimbabwe.

إمكانات توليد الطاقة من مخلفات النخيل

date-palm-biomassيعد تمر النخيل احد المنتجات الزراعية الاساسية في المناطق الجافة و شبه الجافة في العالم خاصة في الشرق الأوسط و شمال افريقيا. يوجد اكثر من 120 مليون شجرة نخيل في العالم تنتج عدة ملايين من الاطنان من التمر كل عام، بالاضافة الي المنتجات الثانوية و التي تشمل عروق النخيل، الأوراق، السيقان، السعف و الليف. يمتلك العالم العربي اكثر من 84 مليون شجرة نخيل و اغلبها في مصر، العراق، المملكة العربية السعودية، ايران، الجزائر، المغرب، تونس و الإمارات العربية المتحدة.

تعتبر مصر اكبر منتج في العالم للتمر حيث بلغ إنتاجها السنوي في عام 2012  1.47مليون طن من التمر و هو ما يمثل حوالي خمس الانتاج العالمي. تمتلك المملكة العربية السعودية اكثر من 23 مليون شجرة نخيل و التي تنتج حوالي مليون طن من التمر في العام. تدر أشجار النخيل كميات هائلة من المخلفات الزراعية في شكل أوراق جافة، سيقان، نوي التمر، بذور، الخ. يمكن لشجرة نخيل واحدة ان تنتج نمطيا ما يقرب من 20 كيلوجرام من الأوراق الجافة سنويا بينما يمثل نوي التمر غالبا 10% من ثمرة التمر. اثبتت بعض الدراسات ان المملكة العربية السعودية وحدها قادرة علي ان تنتج اكثر من 200,000 طن من الكتلة الحيوية لتمر النخيل كل عام. 

يعتبر تمر النخيل من مصادر الطاقة الطبيعية المتجددة لانه يمكن استبدالها في وقت قصير نسبيا. تستغرق شجرة النخيل من 4-8 سنوات حتي تثمر بعد زرعها، ومن 7-10 سنوات حتي يكون حصاد ثمرها اقتصاديا. يتم عادة حرق مخلفات تمر النخيل في مزارع او يتم التخلص منها في مقالب القمامة مما يسبب تلوث بيئي في مناطق انتاج التمر. في بلدان مثل العراق و مصر يستخدم جزء صغير من الكتلة الحيوية للنخيل في انتاج الأعلاف الحيوانية.

الكتلة الحيوية للنخيل تحتوي علي المكونات الاساسية الآتية سليولوز و هيميسليولوز و اللغنين. بالاضافة الي ذلك يحتوي النخيل علي نسبة عالية من المواد الصلبة المتطايرةو نسبة منخفضة من الرطوبة. و بفضل هذه العوامل و المكونات تكون الكتلة الحيوية للنخيل مصدرا ممتازا لإنتاج الطاقة من المخلفات في منطقة الشرق الأوسط و شمال افريقيا. يوجد نطاق واسع من تكنولوجيات حرارية و كيمياء حيوية تستخدم لتحويل الطاقة المختزنة في الكتلة الحيوية للنخيل الي عدة صور مفيدة من الطاقة. وجود نسبة رطوبة منخفضة في تمر النخيل تجعل مخلفاته مناسبة تماما لتكنولوجيا التحويل الحراري و الكيميائي مثل الإحراق و التحويل الي غاز و الانحلال الحراري.

علي الجانب الاخر، وجود نسبة عالية من المواد الصلبة المتطايرة في الكتلة الحيوية للنخيل تدل علي إمكانيتها لإنتاج غاز حيوي في مصانع التهضيم اللاهوائي، و من الممكن بواسطة التهضيم المشارك مع المخلفات الصلبة للصرف الصحي، المخلفات الحيوانية  و النفايات الغذائية. يمكن تحويل المحتوي السليولوزي في مخلفات النخيل الي وقود حيوي (إيثانول حيوي) عن طريق استخدام عملية التخمير. و بالتالي فان وجود أشجار النخيل بوفرة في بلدان مجلس التعاون الخليجي، و علي الأخص المملكة العربية السعودية، يحفز علي تطوير قطاعي الكتلة الحيوية و الوقود الحيوي في المنطقة.

Solid Waste Management in Tunisia

Solid waste management has emerged as a big challenge for the Mediterranean country of Tunisia. The country, having an estimated population of around 11 million people, produces more than 2.5 million tons of garbage each year. Tunisia is experiencing an average increase in waste volume by 3% with per capita waste generation in urban areas being 0.8 kg per day. Biodegradable organic fraction constitutes around 68% of the MSW stream.

MSW collection is covered at 80% in urban areas and 10% in rural areas. The country has 10 controlled landfills with a capacity of 1,788,000 tons per year and four other semi-controlled landfills in the Valley Medjerda with a capacity of 62,000 tons per year. Five other discharges with a nominal capacity of 0.466 million tons per year are being built and finally five other controlled discharges are planned with an average capacity of 0.433 million tons per year. Many municipal landfills do not meet sanitary standards and waste is often dumped into non-sanitary areas. Interestingly, only five percent of MSW is composted and merely 4% recycled. The expenditure for waste collection and transport constitutes 75-100% of the total solid waste management budget.

Borj Chakir Landfill

Eight kilometers south of Tunis is Borj Chakir, a town that has become infamous for a landfill that has damaging effects on the surrounding environment and quality of life of locals. The Borj Chakir landfill created in 1999 is the largest dumping ground and only regulated landfill in Tunis (which includes the governorates of Tunis, Manouba, Ariana and Ben Arous). The site occupies 120 hectares of what was once agricultural land planted with olive trees and grains. According to the facility specifications published in 1997 the landfill at Borj Chakir is intended for solid waste but current activities shows it operation outside of norms. Over the years the residents of El Attar/Borj Chakir,Jiyara and Sidi Hassine have suffered from compromised health and sanitation as a consequence of the waste collection site that has contaminated air, water, soil and as a result of their exposure to toxic odors of leachate.

Recycling Situation

The country possesses comprehensive environmental laws to encourage the sustainable management and recycling of municipal and industrial waste but there is doubt if the necessary measures for a good application have been provided. The Tunisian Government is often criticized for leaving the responsibility of waste management to the National Waste Management Agency (ANGED).

Borj Chakir landfill is a major cause of environmental and public health concerns.

Every year Tunisians use one billion plastic bags generating 10,000 tons of waste that have wreaked havoc on the environment. Almost 400 Private Companies are authorized by the Ministry of Environment to collect, transport and recycle plastics. Five private collectors and recyclers of used tires were also authorized while paper and cardboard recycling is still in its infancy. There is also a small informal sector for recycling food packaging.

Future Outlook

After the Arab Spring, Tunisia faced additional challenges maintaining existing waste management practices due to repeated strikes and dysfunctioning of municipal and rural council which destabilized cleaning service. There is a general view among the populace that the way waste is managed should be changed towards an integrated management style which entails collection to treatment because of the relationship between environmental impact and effects on human health are apparent. The market for environmental protection, pollution control equipment and technology has significant potential as anticipated tenders for landfills, coastal pollution project and waste water treatment all offer good opportunity for procurement.  

Vanishing Aquifers in MENA

aquifer-menaAquifers are of tremendous importance for the MENA as world's most water-stressed countries are located in the region, including Kuwait, Qatar, UAE, Palestine, Saudi Arabia, Oman, Iran, Lebanon and Yemen. However, aquifers in MENA are coming under increasing strain and are in real danger of extinction. Eight aquifers systems, including those in MENA, are categorized as ‘over stressed’ aquifers with hardly any natural recharge to offset the water consumed.

Aquifers in MENA

Aquifers stretched beneath Saudi Arabia and Yemen ranks first among ‘overstressed’ aquifers followed by Indus Basin of northwestern India-Pakistan and then by Murzuk-Djado Basin in North Africa. The Nubian Sandstone Aquifer in the Eastern end of Sahara deserts (parts of Sudan, Chad, Libya and most of Egypt) is the world’s largest known ‘fossil’ aquifer system and Bas Sahara basin (most of Algeria-Tunisian Sahara, Morocco and Libya) encloses whole of the Grand Erg Oriental. The non-renewable aquifers in the Middle East are the Arabian Aquifer and The Mountain Aquifer between Israel and Palestine. Some parts in MENA like Egypt and Iraq rely on major rivers (Nile, Tigris and Euphrates) but these surface water flows does not reach the ocean now. Needless to say, water demand in arid and dry MENA countries is met primarily by aquifers and seawater desalination.

MENA region is the most water-scarce region of the world. The region is home to 6.3 percent of world’s population but has access to measly 1.4 percent of the world’s renewable fresh water. The average water availability per person in other geographical regions is about 7,000 m3/year, whereas water availability is merely 1,200 m3/person/year in the MENA region. The region has the highest per capita rates of freshwater extraction in the world (804 m3/year) and currently exploits over 75 percent of its renewable water resources.

Primarily global exploitation of groundwater is for agricultural irrigation. In Saudi Arabia, during 1970’s, landowners were given free subsidies to pump the aquifers for improvisation of agricultural sectors. Soon the country turned out to be world’s premium wheat exporters. But as years passed, water consumption was high in such a rate that the aquifers approached total depletion. Government announced peoples demand to be met by desalination, which is an expensive approach to meet agricultural sector requirement. By end of 1990’s agricultural land declined to less than half of the country’s farm land. Saudi Arabia is no more a wheat exporter rather relies almost entirely on imported crop from other countries. Unfortunately, country has exploited nonrenewable and ancient ‘fossil’ aquifers which could not be recharged by any form of precipitation.

Key Issues

Stress on a country’s agricultural and water resources majorly cause problems in human health as well as instability and conflicts over shared resources. Climate change has also exacerbated water availability in the Middle East. Infact, water stresses has triggered brutal civil war in Syria and worsened the Palestine-Israel conflicts over sharing aquifers. The key issues, according to World Bank, in water utilization in MENA are as follows:

  • Unsustainable and inefficient use: Middle East countries have the highest per capita consumption of domestic water in the world with 40-50% leakage in the urban systems. And 50% water withdrawn for agriculture does not reach as intended.
  • Ineffective policies: the countries diverts 85% of water to grow crops which would be better importing.
  • Deteriorating water quality: contaminated water systems due to insufficient sanitation infrastructure has caused negative impacts on environment and health issues. Like, in Iran where issues associated with inadequate waste water collection and treatment cost estimated 2.2% of GDP.
  • Excessive reliance on the public investment on water accounts for 1-5 percent of GDP.

In MENA an unexpected climate change is likely to bring 20% rainfall reduction and high rate of evaporation which intensifies water stress. And proportionate climate initiated human behavior, more it gets dry, less water in the river, more tendencies to substitute by groundwater. Also depletion of water below the ground will rise to other disasters like sea water intrusion, land subsidence, especially in Arabian Peninsula, in turn destroys the constructions, infrastructures and developments of the country made-up till date.

Tips to Save Aquifers

We do not know how much water is remaining beneath, but we must understand it is vanishing at a very high rate. MENA must treasure aquifers and natural water resource as same as oil reserves are valued. Individual can play a significant role in saving aquifers in MENA by adopting these simple water conservation guidelines

  • Do not drain cooking oil or grease into sink; use adequate amount, reuse like as a shovel cleaner, polish or donate to machinery shops.
  • Effective use of tap; do not run water while brushing. During winters, store the initial cold water that runs out of the tap prior to the hot water from heater. And also know the convenient tap adjustments.
  • Maintain healthy, hygienic and sanitation practices.
  • Replace conventional water pumps and home appliances with advanced water conservative ones.
  • Avoid unnecessary products, food materials and reduce wastage; water consumed in a diet account’s 92% of water footprint of an individual.
  • Avoid sprinklers for irrigation and in garden use to avoid water loss by evaporation and substitute with efficient water distribution system.

By nature, water is definite in this ‘blue planet’. But when there is no right quantity of water at right quality and time it is called ‘Crisis’.

Solar Energy Prospects in Tunisia

Tunisia is an energy-dependent country with modest oil and gas reserves. Around 97 percent of the total energy is produced by natural gas and oil, while renewables contribute merely 3% of the energy mix. The installed electricity capacity at the end of 2015 was 5,695 MW which is expected to sharply increase to 7,500 MW by 2021 to meet the rising power demands of the industrial and domestic sectors. Needless to say, Tunisia is building additional conventional power plants and developing its solar and wind capacities to sustain economic development.

Wind Energy Outlook

Wind power represents the main source of renewable energy in Tunisia. Since 2008, wind energy is leading the energy transition of Tunisia with a growth of the production up to 245 MW of power installed in 2016. Two main wind farms have been developed until now: Sidi-Daoud and Bizerte. 

The first wind power project of Tunisia started in 2000, with the installation of the Sidi-Daoud’s wind farm in the gulf of Tunis. The station has been developed in three steps before reaching its current power capacity of 54 MW. The operation of two wind power facilities in Bizerte – Metline and Kchabta Station – was launched in 2012. The development of those stations has conducted to a significant increase of electricity generated by wind power, totalizing a production of 94 MW for Kchabta and 95MW in Metline in 2016

 

Solar Energy Potential

Tunisia has good renewable energy potential, especially solar and wind, which the government is trying to tap to ensure a safe energy future. The country has very good solar radiation potential which ranges from 1800 kWh/m² per year in the North to 2600kWh/m² per year in the South. The total installed capacity of grid-connected renewable power plant was around 342 MW in 2016 (245 MW of wind energy, 68 MW of hydropower and 15 MW of PV), which is hardly 6% of the total capacity. 

In 2009, the Tunisian government adopted “Plan Solaire Tunisien” or Tunisia Solar Plan to achieve 4.7 GW of renewable energy capacity by 2030 which includes the use of solar photovoltaic systems, solar water heating systems and solar concentrated power units. The Tunisian solar plan is being implemented by STEG Énergies Renouvelables (STEG RE) which is a subsidiary of state-utility STEG and responsible for the development of alternative energy sector in the country. 

The total investment required to implement the Tunisian Solar Program plan have been estimated at $2.5 billion, including $175 million from the National Fund, $530 million from the public sector, $1,660 million from private sector funds, and $24 million from international cooperation, all of which will be spent over the period of 2012 – 2016. Around 40 percent of the resources will be devoted to the development of energy export infrastructure.

Tunisian Solar Program (PROSOL)

Tunisian Solar Programme, launched in 2005, is a joint initiative of UNEP, Tunisian National Agency for Energy Conservation, state-utility STEG and Italian Ministry for Environment, Land and Sea. The program aims to promote the development of the solar energy sector through financial and fiscal support. PROSOL includes a loan mechanism for domestic customers to purchase Solar Water Heaters and a capital cost subsidy provided by the Tunisian government of 20% of system costs. The major benefits of PROSOL are:

  • More than 50,000 Tunisian families get their hot water from the sun based on loans
  • Generation of employment opportunities in the form of technology suppliers and installation companies.
  • Reduced dependence on imported energy carriers
  • Reduction of GHGs emissions.

The Tunisian Solar Plan contains 40 projects aimed at promoting solar thermal and photovoltaic energies, wind energy, as well as energy efficiency measures. The plan also incorporates the ELMED project; a 400KV submarine cable interconnecting Tunisia and Italy.

In Tunisia, the totol solar PV total capacity at the end of 2014 was 15 MW which comprised of mostly small-scale private installations (residential as well as commercial) with capacity ranging from 1 kW and 30 kW. As of early 2015, there were only three operational PV installations with a capacity of at least 100 kW: a 149 kWp installation in Sfax, a 211 kWp installation operated by the Tunisian potable water supply company SONEDE and a 100 kWp installation in the region of Korba, both connected to the medium voltage, and realized by Tunisian installer companies. The first large scale solar power plant of a 10MW capacity, co-financed by KfW and NIF (Neighbourhood Investment Facility) and implemented by STEG, is due 2018 in Tozeur.

TuNur Concentrated Solar Power Project

TuNur CSP project is Tunisia's most ambitious renewable energy project yet. The project consists of a 2,250 MW solar CSP (Concentrated Solar Power) plant in Sahara desert and a 2 GW HVDC (High-Voltage Direct Current) submarine cable from Tunisia to Italy. TuNur plans to use Concentrated Solar Power to generate a potential 2.5GW of electricity on 100km2 of desert in South West Tunisia by 2018. At present the project is at the fund-raising stage.

Future Perspectives

The Tunisian government has recetly announced plans to invest US $1 billion towards renewable energy projects including the installation of 1,000 megawatts (MW) of renewable energy this year. According to the Energy General Direction of the Tunisian Ministry of Energy and Mines, 650 MW will come from solar photovoltaic, while the residual 350 MW will be supplied by wind energy.

At the same time, the private sector plans to invest an additional US $600 million into the development of renewable energy capacity in 2017. Under new plans, Tunisia has dedicated itself to generating 30 per cent of its electrical energy from renewable energy sources in 2030.

Animal Waste Management in Africa

Livestock and poultry production are among the main economic activities in rural as well as urban areas of African countries.The livestock sector, in particular sheep, goats and camels, plays an important role in the national economy of African countries. In addition, the region has witnessed very rapid growth in the poultry sector.

However, livestock industry is contributing heavily to greenhouse gas emissions and waste management problems in Africa due to the absence of a sustainable Animal Waste Management System in the region. Most of the manure is collected in lagoons or left to decompose in the open which presents a severe environmental hazard.

The use of anaerobic digestion for animal waste disposal is an attractive way to address environmental problems, especially methane emissions. Anaerobic digestion of livestock manure is an alternative pathway for managing large organic waste loads and its associated problems encountered in large feeding lots and confined animal feeding operations.

Despite the numerous benefits associated with anaerobic digestion as a sustainable waste management strategy, these combined merits have never been quantified in African countries.The biogas potential of animal manure can be harnessed both at small- and community-scale. An essential aspect for adopting anaerobic digestion systems is the development of a methane market that acknowledges role of biogas systems in mitigating climate change.

With the present energy and pollution problem in Africa, conversion of animal manure as source of clean energy as well as organic fertilizer offers a great advantage. Anaerobic digestion technologies can help preserve and integrate livestock production within communities and create renewable energy resources to serve a growing bio-economy within rural communities.

Anaerobic digestion is a controlled biological treatment process that can substantially reduce the impact of livestock and poultry manures on air and water quality. An anaerobic digestion plant produces two outputs, biogas and digestate, both can be further processed or utilised to produce secondary outputs. Biogas can be used for producing electricity and heat, as a natural gas substitute and also a transportation fuel.

A biogas plant is a decentralized energy system, which can lead to self-sufficiency in heat and power needs, and at the same time reduces environmental pollution. The main features of a biogas facility are as follows:

  • Processing of renewable energy source
  • Reduction of malodors
  • Removal of harmful pathogens
  • Reduction of COD & BOD contents of processed waste
  • Production of organic fertilizer for green areas
  • Reduction in emissions of greenhouse gases
  • Production of relatively clean water for flushing or irrigation

Animal manure-to-biogas transformation has enormous potential in reducing greenhouse gas emissions and harnessing the untapped renewable energy potential of animal manure. Biogas can be used as a fuel for internal combustion engines, to generate electricity from small gas turbines, burnt directly for cooking, for space and water heating. or for running vehicles.

The City of Nouakchott – Perspectives and Challenges

Nouakchott, capital city of the Islamic Republic of Mauritania, is the biggest city in the Sahara region. Like other major cities worldwide, the city is plagued by environmental, social and economical challenges. Sewage disposal network, dating back to 1960’s is no longer sufficient for Nouakchott. The country is heavily dependent on fossil fuels and woody biomass for meeting energy requirements, though there is good potential of solar, wind and biomass energy. Solid waste management is becoming a major headache for city planners. Population is increasing at a tremendous pace which is putting tremendous strain on meagre civic resources.

Making of a City

Mauritania is a Western African country bordered by the Atlantic Ocean, Morocco, Algeria, Mali and Senegal. Most of its 1,030,700 km2 are covered by deserts. A country as wide as Egypt, it is only scarcely inhabited by some 3.500.000 people. A crossing of cultures, most of the country is inhabited by Arab nomads, the Moors, while the South is inhabited by the African Toucouleur and Soninke people.

Before the country became independent in 1960, the French founded the new capital city Nouakchott. Originally, Nouakchott was a city intended for 3.000 inhabitants. Most of the inhabitants were nomads and the city was established at a meeting place and cattle fair for the nomads. The etymology of the name may mean salt marsh or shore. The area is flat, protected from the sea by low dunes and originally bordered by savannah type vegetation.

After independence, the city grew very quickly, well beyond the expectation of its French founders. In the 1970’s Mauritania sided with Morocco in the Western Sahara war, and was badly defeated by the Polisario rebels. The war caused a massive arrival of refugees from the combat zones in Northern Mauritania. At the same time, drought and famine devastated the whole Sahel region which causes a large-scale refugee influx in the Nouakchott region.

Problems Galore

The arrival of refugees swelled the population of the city, making it the fastest growing city in the region, apart from causing a massive disruption in the environment. For decades, the majority inhabitants of Nouakchott lived in slums. The refugees came with their cattle and contributed to the destruction of existing savanna vegetation by overgrazing. The sand dunes quickly became loose and began to threaten the city from the East and North. Chaotic urbanization caused further environmental destruction, destroying the littoral zone.

The city also suffered social problems, as traditional ways of life disappeared. Former shepherds, agricultural workers and freed slaves became urban poors with little education and abilities to fit in a new economical model. The modern way of life lead to proliferation in plastics items and the landscape of Nouakchott got littered with all sorts of wastes, including plastic bags and bottles.

Nouakchott continues to grow with population reaching one million. However there is stark absence of basic amenities in the city.  Apart from several wells, there are no potable water supplies. The city had no bituminous road beside the two main avenues until recently. The city lacks urban planning, wastewater management and waste management. The construction of harbour and urbanization has led to the destruction of the littoral dunes. The city is in real danger of being flooded in case of sea storm or high tide. The most threatened place is Tevragh Zeina, the most affluent part of the city.

Sand dunes are another cause of worry for Nouakchott. In the 1990’s a Belgian project for the construction of a green belt helped in stopping the progression of dunes. However with expansion of the city, people have now started to build their dwellings in the green belt. The city is also at risk of being flooded in case of rain. In September 2013, during late rainy season, several parts of the city were flooded by rain. Parts of the city are still marked by semi-permanent sewage pools which are a major threat to public health.

Silver Lining

Environment and sustainable development has become a priority during rule of President Mohamed Ould Abdelaziz. The government has built roads in Nouakchott and constructed a water abduction system for bringing water from the Senegal River. Slums have been replaced by social dwellings for the poorest.  New schools, hospitals and universities are sprouting at a rapid pace.

Plans are underway to develop the interior of the country to stop internal immigration to Nouakchott. The country is also making made ambitious climate change strategies and has banned the use of plastic bags which has led to its replacement by biodegradable or reusable bags. Mauritania has rich biodiversity, especially in its sea. Infact, the country has many biodiversity hotspots which may attract people for ecotourism. 

There are huge challenges to be tackled to transform Nouakchott into a modern city. Due to nomadic links, Mauritania’s Arabs have a special link to desert and are counted among the environmentally-conscious people of Western and North Africa. However considerable efforts are required to educate the people living in and around Nouakchott and motivate them to become an active participant in sustainable development of the city.

Sustainability in MENA Cement Industry

The population in the MENA countries has doubled during the last 30 years (from ca. 110m in 1980 to almost 220m in 2010). As per conservative estimates, the rate of urbanisation in the MENA countries will exceed 70% five years from today (average for all developing countries: 54%). The proceeding urbanisation and the population increase involve several problems and challenges for the national governments and also for the cement industry. The cement production of countries in the MENA region has almost tripled during the last 15 years up to approximately 500m tons  Since the start of national revolts and demonstrations in MENA countries in 2011 the problems of especially young Arabs have attracted the attention worldwide.

Environmental problems that accompany a fast growing population and increasing urbanisation are, among others, increasing consumption of energy and raw materials, increasing land use in order to satisfy the increasing food demand, infrastructure development, disposal of increasing amounts of waste and development of sewage systems. Solving these generation spanning problems is a challenging task for the national governments.

Naturally, such high growth rates also affect the cement industry. In the MENA countries it consists of various companies, part of them listed on the stock exchange. A number of cement companies has, partly for cost aspects, responded to the negative consequences of the rapid population growth. The following paragraphs describe the cement industry’s approaches to push a sustainable development in certain sectors. They are partly driven by own responsibility and partly by regulations of the national governments. In this context it should be mentioned that the growth of the cement industry is already partly limited by factors that are directly connected with sustainability and raw material supply.

Although the factors differ from country to country and cannot be generalised, there are a few major concerns, for example:

  • Fuel shortage
  • Dependence on oil
  • Lack of investment in innovations

Let’s have a closer look on the limiting factors and innovation potential based on practical examples.

Saudi Arabia

In many industrialised countries the continuous and tailored supply of the industry with fossil fuels is only a question of price.  But the fact that of all countries, it was cement plants in the own country that repeatedly reported shortages of fossil fuel supply (heavy fuel oil), was certainly an important reason for the government to get closely involved in this matter.

Cement producers in the Kingdom of Saudi Arabia obtain state-subsidised natural gas at a price of US$ 0.75/mmbtu from the state-owned oil company “Saudi Aramco”. Formerly, the cement production costs resulting thereof were on average US$ 28.8/ton of cement (costs in neighbouring countries: Kuwait US$ 59.2/ton, UAE US$ 47.8/ton, Oman US$ 37.0/ton) which made it redundant to deal with the topic of energy. In India, a country with one of the highest energy costs in the world, the production of one ton of cement costs US$ 70.0/ton in 2010.

Due to such low energy prices and a steadily growing demand the production capacities grew constantly. Currently, the industry accounts for approximately 40% of the overall energy demand of the country. Analysts estimate that this demand will even double within the next 15 years. However, it is planned to reduce this disproportionate energy demand of the industry.

Under the patronage of HRH Prince Abdulaziz bin Salman, the state-owned oil company “Saudi Aramco” is developing a so-called “Mandatory Energy Efficiancy Program” (MEEP) for the entire Saudi-Arabian industry. The plan of MEEP is to “establish mandatory policies and regulations with the objective of reducing existing and future energy consumption levels in the industrial sector”.

For the national cement industry this approach implies investments in energy-saving measures. Key points for an energy-efficient industry are identified as

  • Use of alternative raw materials
  • Use of alternative fuels
  • Training and education in energy efficiency

As the use of alternative fuels and raw materials is not yet common in the Kingdom of Saudi Arabia, guidelines and a regulatory framework have to be defined which set standards for the use of alternative or waste-derived fuels like municipal solid wastes, dried sewage sludge, drilling wastes and others. It has to include:

  • Types of wastes and alternative fuels that may be used by the cement industry
  • Standards for the production of waste-derived fuels
  • Emission standards and control mechanisms while using alternative fuels
  • Standards for permitting procedures

Appropriate standards also need to be established for alternative raw materials that are to be used for clinker and cement production. In order to achieve an energy-efficient production special education, further training and workshops for the involved staff have to be carried out.

Egypt

The current political developments in Egypt influence the local cement industry significantly. The government expects additional sources of revenue on the one hand from selling licences for the construction of new cement plants and on the other hand from a reduction of subsidies for fossil fuels. Since these news are not a surprise for the local cement plants, they started to invest in the implementation of alternative – mostly biomass-derived fuels. One of them is CemexAssiut that not only started using different kinds of biomass, but also, most notably and exemplary, established plantations for the production of biomass (here: “Casuarina”) that are irrigated with pretreated sewage water from the city Assiut.

Egypt is the 14th biggest rice producer in the world and the 8th biggest cotton producer in the world. Egypt produced about 5.67 million tons of rice and 635,000 tons of cotton in 2011. The area of cotton crop cultivation accounts for about 5% of the cultivated area in Egypt. The total amount of crop residues is about 16 million tons of dry matter per year. Cotton residues represent about 9% of the total amount of residues. Such high production rates should be welcomed by the cement industry since these materials comprise cotton stalks, rice husks and rice straw which serve ideally as alternative fuels.

The use of waste-derived alternative fuels is, however, more complicated. Although for example Cairo produces some 15,000 tons of waste each day, it is not easy for the cement plants to obtain this waste since they are in direct competition with the informal sector that controls approx. 60% of the local waste total. So-called Zabbaleen or scavengers – mostly young people who do not have other options – make their living by collecting and selling waste-derived recyclables.

Tunisia

Some years ago, Tunisia already invested in the establishment of an organised waste management system in form of a state-owned agency named “ANGED”. Funded by the national German KfW development bank, numerous waste collection points as well as organised landfills have been built. Additionally, a special collection centre for hazardous waste was erected in Jradou. This centre was operated by MVW Lechtenberg’s Partner Nehlsen AG, the German Waste Management Group, collecting and processing wastes like used oils and solvents. Such wastes are ideal alternative fuels. A fact that is also known to the local cement companies that planned to use them in their plants. Unfortunately, due to public opposition the centre was closed and the projects for the processing of alternative fuels have been suspended since then.

Tunisia is one of the biggest producers and exporters of olive oil in the world. It also exports dates and citrus fruits that are grown mostly in the northern parts of the country. It seems paradox that for example olive kernels – the waste from Tunisian olive production – is exported to European power plants in order to save fossil fuel-derived CO2 emissions there, while Tunisia imports approximately 90% of its energy demand, consisting of fossil fuel.

Morocco

The Moroccan cement industry has already achieved a greater success regarding the use of alternative fuels. Cement plants, mostly owned by the international companies Lafarge, Cimpor, Holcim and Italcimenti, already invested years ago in the environmentally friendly use of alternative fuels and alternative raw materials due to the development of world market prices. Also the only local competitor, CIMAT, has started preparing for the implementation of alternative fuels immediately after completion of its new plant (a 5-stage double string calciner from Polysius) in Ben Ahmed, near Casablanca.

In the year 2003 an agreement on the use and import of alternative fuels (used tyres at the time) was made between the Association Professionelle de Ciment and Moroccan government. Since last year attempts are being made to agree on an industry regulation that sets standards for the use of all appropriate special waste available in Morocco.

United Arab Emirates

The United Arab Emirates, represented by Dr. Rashid Ahmad Bin Fahd, Minister of Environment and Water, recently issued a decision streamlining the activities of cement plants all over the country. The resolution will affect all existing and new cement factories across the country. Its provisions obligate the industry to prepare a report assessing the impact of cement plants on the environment.

According to the decision, this report has to be prepared by a consulting firm having expert knowledge regarding environmental protection in the cement industry. This is certainly the first step to evaluate the current situation which will be followed by an investigation of alternatives towards a sustainable development. Interest in the implementation of alternative fuels already exists among the national cement industry which is proven not least by the numerous planned investment projects.

Conclusions

The cement industry in the MENA region will change significantly within the next years. This change will focus on the improvement of energy efficiency and on the increased use of alternative raw materials and alternative fuels. This will include high investments in technology and in the human resources sector where the creation of new jobs, especially in the field of environmentally friendly and sustainable development, provides a perspective for the growing, young population of the MENA countries.

Egypt’s Water Crisis and Degeneration of Nile

pollution-nileEgypt is struggling to cope with water shortages and food production. It is expected that Egypt’s per capita annual water supply will drop from 600 cubic meters today to 500 cubic meters by 2025, which is the UN threshold for absolute water scarcity. Egypt has only 20 cubic meters per person of internal renewable freshwater resources, and as a result the country relies heavily on the Nile for its main source of water. Water scarcity has become so severe that it has been recorded that certain areas in the country could go days without water, with pressure sometimes returning only for a few hours a week. The country can no longer delay action and must act now.

Agriculture

Agriculture contributes roughly 15% of Egypt’s GDP, and employs 32% of Egypt’s workforce with rice being the biggest produce in the country. Rice is an important part of an Egyptian family’s diet. However, the cultivation of rice is very water intensive. On average about 3000 liters of water is used to produce 1 kilo of rice. This number can vary depending on climate, soil type and water management practices.

The government has restricted cultivation of rice to an area of 1 million acres (farmers were previously able to use most of the Nile Delta for cultivation) in specified areas of the Nile Delta. The government has even resorted to taking drastic measures as spreading incendiary compounds on rice fields cultivated outside the area allocated by the government. This has caused outrage and demonstrations by farmers who insist that the area allocated is not enough for them to be able to make ends meet. This type of tension caused by the lack of water was one of the catalysts of the Arab Spring in 2011/2012.

To alleviate population tension and unrest the government has been trying to increase water supply by exploring with reusing treated agricultural and municipal wastewater for agriculture. However implementation of such initiatives is not being applied fast enough to cope with the rising demand. Government must enforce new irrigation methods in the country (Egyptian farmers still rely heavily on flood and canal irrigation in the Nile Delta) as well as smart agricultural practices such as using less water intensive crops. Resorting less water intensive water crops could drastically cut water used in agriculture and help increase water supply.

Pollution of the Nile

The Nile has been a lifeline for Egypt at least since the time of the pharaohs. Yet, despite the world’s largest river’s importance to the country, its water is being polluted by various sources, and pollution levels increasing exponentially in recent years.

The degeneration of the Nile is an issue that is regularly underestimated in Egypt. With so many people relying on the Nile for drinking, agricultural, and municipal use, the quality of that water should be of most importance. The waters are mainly being polluted by municipal and industrial waste, with many recorded incidents of leakage of wastewater, the dumping of dead animal carcasses, and the release of chemical and hazardous industrial waste into the Nile River.

Industrial waste has led to the presence of metals (especially heavy metals) in the water which pose a significant risk not only on human health, but also on animal health and agricultural production. Fish die in large numbers from poisoning because of the high levels of ammonia and lead. Agricultural production quality and quantity has been affected by using untreated water for irrigation as the bacteria and the metals in the water affect the growth of the plant produce, especially in the Nile Delta where pollution is highest.

Industrial pollution is wrecking havoc in Nile

Industrial pollution is wrecking havoc in Nile

Of course the pollution of Nile is a complex problem that has been continuing for more than 30 years and the government is trying to implement stricter rules on the quality and type of waste/wastewater dumped into the river to reduce the pollution of the Nile. However, swift and decisive action must be taken towards cleaning the Nile, such as treating the wastewater prior to disposal, and placing stricter restrictions on industries to dispose of their waste safely and responsibly. This issue cannot be ignored any further as the continual increase in population will cause an increase in demand on Egypt’s dwindling water resources. Every drop of water counts.

The Blue Nile Dam

Another challenge at hand is tackling the issue of Ethiopia building a dam and hydroelectric plant upstream that may cut into Egypt’s share of the Nile. For some time a major concern for Egypt was Ethiopia’s construction of the Grand Ethiopian Renaissance Dam (GERD) in the Blue Nile watershed, which is a main source of water for the Nile River. Construction of the Renaissance Dam started in December 2010, and has the capacity to store 74 to 79 billion cubic meters of water and generate 6,000 megawatts of electricity for Ethiopia a year. This creates major concern for Egypt, who is worried that this damn would decrease the amount of water it receives (55.5 billion cubic meters) from the Nile River. Egypt is concerned that during dry months, not enough water will be released from the GERD thus decreasing the water received downstream. This will greatly hinder Egypt’s attempts to alleviate the water shortages during those months.

Earlier this year, Egypt, Ethiopia and Sudan assigned two French companies to prepare a report on the impact of the dam on the three countries. This report will clarify the affects the Dam will have on downstream countries. The results of this report are yet to be released. 

Conclusion

In case of business-as-usual scenario, Egypt runs the risk of becoming an absolute water scarce country in less than a decade. Therefore Egypt has a battle on its hands to ensure adequate conditions for its population. Like many other water scarce countries around the world, it needs to mitigate water scarcity by implementing smart conservation techniques, adopting water saving technologies, and control water pollution. With climate conditions expected to get drier and heat waves expected to become more frequent in the MENA region, Egypt cannot afford to neglect its water conservation policies and must act immediately to meet the population’s water demand.

Waste Management Perspectives for Egypt

Egypt occupies 7th position in the list of countries with the most mismanaged plastic waste, according to a recent report published in Science magazine. The report was based on data collected in 2010 and one must wonder whether the results of the report would have been different if the zabbaleen had been allowed to continue their work unhindered.

A History of the Zabbaleen

The zabbaleen, or garbage collectors, are the descendants of farmers from Upper Egypt who moved to Cairo in the 1940s. Together with another migrant group, they have made a living in Cairo collecting, sorting, salvaging, and recycling the waste of the city's nearly 20 million residents. With the help of NGOs, the zabbaleen recycled up to 80% of the waste they collected, more than three times the amount of waste recycled by garbage collectors in major cities in developed nations. The zabbaleen collected the garbage free of charge; they were part of Cairo's informal public sector. Their work was not supported by the government. Their income came from selling the recyclable material and from the pigs they raised on the organic waste. Many residents also gave monetary tips to the garbage collectors. This meager income barely supported the zabbaleen, who live together in different settlements around the city, all of them extremely poor.

Believing the zabbaleen's system to be backwards and unhygienic, in 2003, the government sold contracts to three multinational companies (and one local company) to collect Cairo's waste, pushing the zabbaleen out of the system. These companies were required to recycle only 20% of the waste collected, the other 80% making its way to landfills. It did not take long for residents to complain about this new service. They now had to pay for their garbage collection and that did not include door-to-door pick-up. There were not enough bins in the streets to hold all the waste and streets quickly filled with the overflowing garbage. The new companies simply could not keep up with the waste being produced. Not only did this have a devastating effect on the waste management situation in Cairo, it destroyed the zabbaleen's way of life as they lost access to the garbage that was the foundation of their economic activities. At one point, the private companies realized they needed the zabbaleen and tried to subcontract them, but the zabbaleen were highly underpaid and the system failed. Some residents, though, continued to hire the zabbaleen on their own.

Adding to both the city's garbage woes and the plight of the zabbaleen, in 2009, in response to the H1Ni influenza outbreak, the government ordered the culling of all the zabbaleen's pigs. These pigs were an essential part of the zabbaleen's recycling program. The pigs consumed all of the organic waste that was sorted from the garbage. When they lost their pig herds, the zabbaleen stopped collecting organic waste and the effect was felt almost immediately. Again, residents complained about the trash piling up on the streets. The trash piles became home to rats and disease. And once again, the zabbaleen suffered as they were no longer able to earn enough money to support themselves and had lost an important food source.

Change is in the Air

Since the 2011 revolution, many changes have taken place in Egypt, spurred on by environmentally-minded individuals, small businesses, and new government ministers. One of the more hopeful changes involves the collection of garbage. The government has finally implemented a proposal for officially employing the zabbaleen, replacing the international companies with smaller zabbaleen-run companies. Once registered, the local companies are given uniforms, government vehicles and business training from an NGO. The system had a test-run and debuted in a few areas late last year. If successful, there are plans to expand over the next two years. This is good news for Cairo's waste management and even better news for the zabbaleen.

Other private-sector initiatives are tackling recycling as well.  Recyclobekia is a new company that offers electronic waste recycling services. The company collects, sorts, and dismantles e-waste – old laptops, computers, cameras, phones, and more – and in return companies and individuals are given credit for an online shop or even cash if they recycle more than 500 kg of waste. GreenTec is an exciting recycling initiative that offers Automated Recycling Machines. With these machines, individuals can deposit their plastic water bottles and receive credit for their mobile phones. Another new venture coming out of Cairo is Refuse, a company that upcycles plastic bags and creates backpacks, tote bags, laptop covers, and other accessories with this waste. They also offer workshops to teach others how to upcycle.  Gamayit El-Misbah El-Mudii, started in 2005, provides free collection and recycling of paper, plastic, glass, and other items. They collect from individuals, schools, and businesses. Resala, a charity organization, also offers recycling services. As these initiatives and companies continue to grow, so will the awareness and action of individuals in terms of waste management and recycling.

Individual Action

While our local and national authorities attempt to improve the collection and recyling of our waste at the city level, it is important to remember that we as individuals can do a lot as well. The first and simplest action we can take it to sort our trash into organic and non-organic waste. Our garbage collectors, whoever they may be, will appreciate this effort and it will keep any paper or board waste clean so that it can be recycled. Once you've sorted your trash, make sure it's getting recycled. If the zabbaleen do not collect in your area, contact one of the organizations listed above. The most important action we can take is to reduce the amount of waste we are creating in the first place. Less waste produced means less waste needing to be managed. We can start by refusing to use or purchase disposable plastic. Bring your own reusable bags to the supermarket so that you don't need the plastic ones. Invest in a water filter and a reusable bottle so you can drink your tap water and skip the plastic water bottles. Avoid buying food packaged with polystyrene; it's not recyclable. Read this guide to a plastic-free life and search other websites for tips and ideas on reducing plastic waste. You'll find that most of the suggestions will be better for your health and the health of our environment, and at the same time, save you money. If we all do our part by taking these steps, perhaps Egypt won't make the top ten list of worst plastic offenders again.

Role of CSP in South Africa’s Power Sector

Demand for electricity in South Africa has increased progressively over several years and the grid now faces supply and demand challenges. As a result, the Department of Energy has implemented a new Integrated Resource Plan to enhance generation capacity and promote energy efficiency. Photovoltaics (PV) and concentrated solar power (CSP) are set to be the main beneficiaries from the new plan having their initial allocation raised considerably.

Daily power demand in South Africa has a morning and evening peak, both in summer and winter. This characteristic makes CSP with storage a very attractive technology for generating electricity on a large scale compared to PV, which currently can provide electricity at a cheaper price, but its capability to match the demand is limited to the morning demand peak.

As experts highlight, CSP is the only renewable technology that provides dispatchable electricity that adapts to the demand curve, though at a higher price than PV. However, the government in South Africa has recognized the flexibility that it offers to the grid (matching the demand and stabilizing the system) over the levelised cost of energy (LCOE), and announced a bid window in March 2014 solely for CSP, where 200 MW are to be allocated.

CSP’s operational flexibility allows the plant to be run in a conventional mode at maximum power output, store the excess energy and use the full load once the sun starts setting. Another option is to adapt the production to the demand, reducing the load during the central hours of the day where PV can provide cheaper electricity, and shift that energy to generate at later hours without requiring a large storage system.

Renewable Energy Prospects in Africa

With a sixth of the world’s population, Africa generates a measly four percent of the world’s electricity, three-quarters of which is used by South Africa and northern Africa. According to World Bank statistics, more than 500 million Africans (almost two-thirds of the total population) have no access to “modern energy.” Hydropower accounts for around 45% of electricity generation in sub-Saharan Africa (SSA) while biomass (mostly firewood) constitutes about 56 percent of all energy use in sub-Saharan Africa. Large-scale use of forest biomass is accelerating deforestation, and the World Bank estimates that 45,000 square kilometers of forest were lost between 1990 and 2005 across all low-income countries in Africa.

Africa has huge renewable energy potential with some of the world’s largest concentration of alternative energy resources in the form of solar, wind, hydro and biomass energy. Overall, 17 countries in sub-Saharan Africa are in the top-33 countries worldwide with combined reserves of solar, wind, hydro, and geothermal energy far exceeding annual consumption. Most of the sub-Saharan countries receive solar radiation in the range of 6-8 kWh/m2/day, which counts among the highest amounts of solar radiation in the world. Until now, only a small fraction of Africa’s vast renewable energy potential has been tapped.  The renewable energy resources have the potential to cover the energy requirements of the entire continent.

Several African counties, such as South Africa, Egypt, Morocco, Kenya, Senegal, Madagascar, Rwanda and Mali have adopted national targets for renewable energy, and feed-in tariffs for renewable energy electricity have been introduced e.g. in South Africa and Kenya.   Countries such as South Africa, Morocco, Egypt, Cape Verde, Ethiopia, Kenya and Tanzania are developing wind farms.  Geothermal investments are increasing in the Rift Valley area of Eastern Africa.  The pipeline of investments in Africa in hydropower, wind farms, solar PV and concentrated solar thermal, geothermal power and biomass energy underlines the huge potential for a future expansion of renewable energy across the continent.

The African Development Bank, through its public and private sector departments, is currently implementing several clean energy projects and programs to address these priorities particularly in the energy and forestry sectors. The Bank's energy portfolio currently stands at about USD 2 billion. The AfDB provides two lending windows. The first is a public window, with mostly concessional funds available to governments. The second is a private window, which offers debt and equity on commercial terms. 

Hydroelectric power generation represent an attractive investment in Africa because of tremendous hydropower generation potential, 60% of which is locked within Guinea, Ethiopia and the Democratic Republic of Congo. The AfDB has committed its support to developing the Gibe III hydroelectric dam, in Ethiopia. Wind farms are another lucrative investment arena for AfDB, as shown by AfDB’s commitment for 300MW Lake Turkana Wind Farm in Kenya.  Lake Turkana Wind Power (LWTP) consortium is constructing a wind farm consisting of 353 wind turbines, each with a capacity of 850 kW, in Northwest Kenya near Lake Turkana. The wind power project is expected to reach full production of 300 MW by the end of 2012.  LTWP can provide reliable and continuous clean power to satisfy up to about 30% of Kenya’s current total installed power. 

The Ain Beni Mathar Integrated Solar Thermal Combined Cycle Power Station is one of the most promising solar power projects in Africa.  The plant combines solar power and thermal power, and is expected to reach production capacity of 250MW by 2012. African Development Bank, in partnership with the Global Environment Facility and Morocco's National Electric Authority, is financing approximately two-thirds of the cost of the plant, or about 200 million Euros.

With growing concerns about climate change, AfDB has compiled a strong project pipeline comprised of small- to large-scale wind-power projects, mini, small and large hydro-power projects, cogeneration power projects, geothermal power projects and biodiesel projects. The major priorities for the Bank include broadening the supply of low-cost environmentally clean energy and developing renewable forms of energy to diversify power generation sources in Africa. The AfDB’s interventions to support climate change mitigation in Africa are driven by sound policies and strategies and through its financing initiatives the Bank endeavors to become a major force in clean energy development in Africa.
