CSP-Powered Desalination: Prospects in MENA

By | | , ,
5 Comments

Conventional large-scale desalination is cost-prohibitive and energy-intensive, and not viable for poor countries in the MENA region due to increasing costs of fossil fuels. In addition, the environmental impacts of desalination are considered critical on account of GHG emissions from energy consumption and discharge of brine into the sea. The negative effects of desalination can be minimized, to some extent, by using renewable energy to power the plants. What is Concentrated Solar Power The core element of Concentrated Solar Power Plant is a field of large mirrors reflecting captured rays of sun to a small receiver element, thus concentrating the … Continue reading →

Sustainability in the MENA Cement Industry: Perspectives

By | | , , ,
6 Comments

The population in the MENA countries has doubled during the last 30 years (from ca. 110m in 1980 to almost 484m in 2018). 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 … Continue reading →

The MENA region produces huge quantity of municipal wastewater which represents a serious problem due to its high treatment costs and risk to environment, human health and marine life. The per capita wastewater generation rate in the region is estimated at 80-200 litres per day. Sewage generation across the region is rising by an astonishing rate of 25 percent every year. Municipal wastewater treatment plants in MENA produce large amounts of sludge whose disposal is a cause of major concern. For example, Kuwait has 6 wastewater treatment plants, with combined capacity of treating 12,000m³ of municipal wastewater per day, which produce around … Continue reading →

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 waste 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 … Continue reading →

Agriculture plays an important role in the economies of most of the countries in the Middle East and North Africa. The contribution of the agricultural sector to the overall economy varies significantly among countries in the region, ranging from about 3.2 percent in Saudi Arabia to 13.4 percent in Egypt.  Large scale irrigation is expanding, enabling intensive production of high value cash and export crops, including fruits, vegetables, cereals, and sugar. Egypt 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 … Continue reading →

Climate Change Mitigation in Tunisia: Challenges and Progress

Climate change has become a reality in Tunisia, which is struggling to cope with the problems of desertification, water scarcity and the degradation of natural resources. Despite its limited carbon footprint, the risks of climate change may be high. The fourth Arab country to have published its Intended Nationally Determined Contributions (INDC) for a reduction in greenhouse gas emissions, Tunisia has put climate change on the top of its political and economic agenda. It is also the first country in the region to include in its new Constitution recognition of climate change: “A sound and balanced environment while contributing to … Continue reading →

Solar Energy Prospects in Tunisia

By | | ,
12 Comments

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 in Tunisia Wind power represents the main source of renewable energy in … Continue reading →

Desertec: What Went Wrong?

11 Comments

A plan to power Europe from solar power plants in Sahara desert, popularly known as Desertec, seems to have stalled, but several large North African solar projects are still going ahead despite local concerns. Where did the Desertec project go wrong, and can desert solar power yet play a role in a democratic and sustainable future? If you use social media, you may well have seen a graphic going around, showing a tiny square in the Sahara desert with the caption: ‘This much solar power in the Sahara would provide enough energy for the whole world!’ Can this really be true? It is … Continue reading →

Agricultural Biomass in MENA

Agriculture plays an important role in the economies of most of the countries in the Middle East and North Africa region.  Despite the fact that MENA is the most water-scarce and dry region in the world, many countries in the region, especially those around the Mediterranean Sea, are highly dependent on agriculture. The contribution of the agricultural sector to the overall economy varies significantly among countries in the region, ranging, for example, from about 3.2 percent in Saudi Arabia to 13.4 percent in Egypt.  Large scale irrigation coupled with mechanization has enabled extensive production of high-value cash crops, including fruits, … Continue reading →

Energy Efficiency in Arab World: Key Findings of Arab Future Energy Index 2017

Energy efficiency is the most cost effective means of reducing the energy intensity of the economy and promoting a low-carbon future in the Arab world. Energy efficiency further helps Arab states meet their SDGs on combating climate change and its impacts (SDG13), as it cuts down on GHG emissions resulting from excessive and inefficient consumption of energy. Energy efficiency improvements can save governments, companies, and citizens billions of dollars in the Arab region from reduced energy bills, while at the same time quickly reducing carbon footprints – a win-win solution. Many countries in the region are now moving ahead with … Continue reading →
