Africover InitiativeLast Updated on 2013-10-08 23:04:33
The Africover Project is designed to provide a digital, georeferenced database on land cover—and a geographic information reference point for the whole of Africa.
The purpose of the Africover Project is to establish a digital georeferenced database on land cover and a geographic referential for the whole of Africa including:
geodetical homogeneous referential
The Multipurpose Africover Database for the Environmental Resources (MADE) is produced at a 1:200,000 scale (1:100,000 for small countries and specific areas).
Reinforcing national and sub-regional capacities for the establishment, update and use of the geographic referential and land cover maps and spatial data bases is the core strategy of Africover: this has been the methodology adopted to ensure an operational approach and the sustainability of the initiative.

Which fish should I eat?Last Updated on 2013-09-03 12:09:16Despite the relative lack of information integrating the health, ecological, and economic impacts of different fish dietary choices, clear and simple guidance is needed to effect wise consumption of wild and domesticated fisheries resources.

International Food Security Assessment: 2012-22Last Updated on 2012-08-11 00:00:00
Food security is estimated to improve slightly in 2012 as the number of food-insecure people in the 76 countries covered in this report declines from 814 million in 2011 to 802 million in 2012. The share of the population that is food insecure remains at 24 percent. Over the next decade, the share of the population that is food insecure is projected to decline from 24 percent in 2012 to 21 percent in 2022, but the number of food insecure people is projected to increase by 37 million. Regionally, food insecurity is projected to remain most severe in Sub-Saharan Africa. Food-insecure people are defined as those consuming less than the nutritional target of roughly 2,100 calories per day per person.

Bioenergy: Chances and LimitsLast Updated on 2012-07-26 10:38:28
This report from the German National Academy of Sciences Leopoldina has come to the conclusion that in quantitative terms, bioenergy plays a minor role in the transition to renewable, sustainable energy sources in Germany at the present time and probably into the future.
Bioenergy – Chances and Limits
The Leopoldina’s statement “Bioenergy – Chances and Limits” [Bioenergie: Möglichkeiten und Grenzen] provides a comprehensive analysis of the use of bioenergy. It was compiled by a working group of more than 20 expert scientists established in 2010 and outlines under which conditions the utilization of bioenergy is appropriate.
In recent years Germany has seen a steady rise in the number of energy crops being cultivated for the production of biofuels and biogas. Because bioenergy is so versatile and easy to store, the German... More »
CIGAR ConsortiumLast Updated on 2012-07-09 12:25:24
The CGIAR Consortium is a global partnership that unites organizations engaged in research for a food secure future.
The name CGIAR comes from the acronym for the Consultative Group on International Agricultural Research. In 2008 the CGIAR underwent a major transformation. To reflect this and yet retain our roots we have kept CGIAR as our name.
CGIAR research is dedicated to reducing rural poverty, increasing food security, improving human health and nutrition, and ensuring more sustainable management of natural resources. It is carried out by 15 Centers, that are members of the CGIAR Consortium, in close collaboration with hundreds of partner organizations, including national and regional research institutes, civil society organizations, academia, and the private sector.
The 15 Research Centers generate and disseminate knowledge,... More »
