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.

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.

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. … Continue reading

Egypt’s Water Crisis and Degeneration of Nile

Egypt is struggling to cope with water shortages and food production.

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 … Continue reading

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 … Continue reading

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.

The country has 10 controlled landfills with a capacity of 1,788,000 tons per year and four other … Continue reading
