Are Green Roofs a Viable Option for the Middle East?

Urban green roofs have long been promoted as an easy and effective strategy for beautifying the built environment and increasing investment opportunity. The building roof is very important because it has a direct impact on thermal comfort and energy conservation in and around buildings. Urban green roofs can help to address the lack of green space in many urban areas. Urban green roofs provides the city with open spaces that helps reduce urban heat island effect and provides the human population on the site with a connection to the outdoors. However, we must differentiate between two types of urban green … Continue reading

Food Security in the Middle East

Despite the fact that the Middle East is blessed with a rich geological inheritance of hydrocarbons and mineral resources, it is a water-scarce and arid region that has its share of demographic and socio-economic problems. It is difficult to grow food crops in the Middle East due to scarcity of water supply and limited availability of arable land. The region is highly vulnerable to fluctuations in international commodity markets because of heavy dependence on imported grains and food items.   According to a report issued in 2009 by the World Bank, the United Nations Food and Agriculture Organization (FAO) and … Continue reading

Introduction to Solar Pond

A solar pond is a three-dimensional, open-air pit, filled with water endowed with special properties. It receives solar energy through insulation, then the trapped heat is extracted from it from the water lying at the bottom of the pond. When solar energy falls onto the pond, it heats the water, splitting it into three sections: the first section is the uppermost layer, or Surface Zone, containing fresh water with a low level of salinity. This owes to the fact that salts gather at the bottom. The second layer is the middle layer, called the insulating layer or Insulation Zone, whose … Continue reading

CDM Projects in MENA Region

The MENA region is an attractive CDM destination as it is rich in renewable energy resources and has a robust oil and gas industry. Surprisingly, countries in MENA host very few and declining number of CDM projects with only 23 CDM projects registered till date. The region accounts for only 1.5 percent of global CDM projects and only two percent of emission reduction credits. The two main challenges facing many of these projects are: weak capacity in most MENA countries for identifying, developing and implementing carbon finance projects and securing underlying finance. The registered CDM projects in MENA countries are … Continue reading

الطاقه المتجددة بالمغرب العربي

المغرب، كونها أكبر مستورد للطاقة في شمال أفريقيا، تبذل جهودا مركزة للحد من اعتمادها على الوقود الأحفوري المستورد. وتعتبر الطاقة المتجددة  مصدر موثوق في بلد مثل المغرب العربي التي لديها الاعتماد الكامل تقريبا على شركات الطاقة المستوردة.والمغرب تنفق سنويا  أكثر من 3 مليارات دولار على واردات الوقود والكهرباء في حين انها تشهد نمو الطلب على الطاقة بمعدل 6.5 في المئة سنويا. وفقا لتقرير الوزارة المغربية للطاقة والتعدين، الطاقة الإجمالية المركبة للطاقة المتجددة (باستثناء الطاقة المائية) ما يقرب من 300ميجا وات في عام 2011. وقد حققت الحكومة المغربية بالفعل هدفها المتمثل في توفير حوالي 8٪ من إجمالي الطاقة الأولية من مصادر … Continue reading

Making a Switch to Circular Economy

All forms of wealth and security, including climate stability, biodiversity, resource availability, soil fertility, air and water purity and health, are depleted by the systemic error of running a linear economy. Linear economics consumes the basis for future growth so what is now growing fastest is unproductive activity, inactivity and instabilities. The credit crunch marks the withdrawal of faith in growth-as-usual and any reliable revival of growth and prosperity requires a switch of vision. Circular Economics The future for growth is circular economics where more economic activity would mean a faster pace of change away from waste-making and towards looking … Continue reading

Unleashing Solar Power in Saudi Arabia

Saudi Arabia is the largest consumer of petroleum in the Middle East, with domestic consumption reaching 4 million barrels per day in 2012 out of daily production of 10 million barrels. Saudi Arabia’s primary energy consumption per capita is four times higher than the world average. Strong industrial growth, subsidized oil prices, increasing energy demand for electricity and transportation is leading to a growing clamor for oil in the country. The total energy consumption in the Kingdom is rapidly rising at an average rate of about 6 percent per annum. Solar Energy Prospects in KSA To meet the rising local … Continue reading

Restocking the Seas around Bahrain through Fish Farming

The marine waters around Bahrain have been showing a decline in fish stock for several decades. But in the first decade of this millennium, restocking has become a routine practice endorsed by the former Public Commission for the Protection of Marine Resources, Environment and Wildlife (now the Supreme Council for the Environment). In recent years, the fishing industry in the Kingdom of Bahrain is starting to really look up with the restocking of the waters from farmed fish. Requirements of a Fish Farm Fish farming means growing fish in fixed enclosures (tanks, ponds or cages) exposed to the natural climatic conditions … Continue reading
