Drylands occupy more than 40% of the world’s land area and are home to some two billion people. This includes a disproportionate number of the world’s poorest people, who live in degraded and severely degraded landscapes. The United Nations Convention to Combat Desertification states on its website that 12 million hectares are lost annually to desertification and drought, and that more than 1.5 billion people are directly dependent on land that is being degraded, leading to US$42 billion in lost earnings each year.

‘Over the past three decades hundreds of thousands of farmers in Burkina Faso and Niger, on the fringes of the Sahara Desert, have transformed large swathes of the region’s arid landscape into productive agricultural land, improving food security for about three million people. Once-denuded landscapes are now home to abundant trees, crops, and livestock.'

The support plan for the Sahel is a regional approach to collectively address the root causes of disruptions such as poverty, migration and youth unemployment, climate change, insecurity, governance and institutional issues in the region. In this report an overview of the current situation for each of the priority areas of the UN Support Plan is presented to demonstrate that the full implementation of the plan could utilize an existing momentum of development not seen in decades in the Sahel.

Peer-reviewed publicationDecember, 2016Burkina Faso, Central African Republic, Cameroon, Algeria, Eritrea, Ethiopia, Mali, Mauritania, Niger, Nigeria, Sudan, Senegal, South Sudan, ChadAfter the severe droughts in the 1970s and 1980s, and subsequent debates about desertification, analyses of satellite images reveal that the West African Sahel has become greener again. In this paper we report a study on changes in tree cover and tree species composition in three village landscapes in northern Burkina Faso, based on a combination of methods: tree density change detection using aerial photos and satellite images, a tree species inventory including size class distribution analysis, and interviews with local farmers about woody vegetation changes.

Feed and grazing management affect both the quantity and quality of animal manure and consequently nutrient cycling in the mixed crop-livestock systems in West Africa Sahel. Dietary measures can significantly influence the composition of manure and hence it’s agricultural value. High nutrient feed will generally result in higher nutrient content of the manure whereas a decline in feed quality will generally lead to increase in the indigestible fractions in the feeds.

Tetra Tech’s land tenure and property rights experts examine how weak land and resource governance can fuel drivers of violent extremism. With a focus on the African Sahel, this new issue brief finds this dynamic is especially prevalent when land and resource governance challenges are coupled with environmental disruptions, resource scarcity, or migration.

For over a decade, the globalisation of environmental, economic and social issues has induced rapid modification in agriculture and land. These changes raise the question of future extensive livestock systems in regards to the worldwide challenge to double livestock production by 2050 in ways which are safe for the environment. In order to better understand and follow modification processes, a comparative study of livestock systems and land dynamics has been carried out on seven case studies on three continents through the use of a common grid.

We propose a flexible and adaptable framework to assist the quick design of models dealing with the durability of the extensive livestock systems at the territorial scale. This metamodel results from the collaborative design starting from MAS developed on 7 sites in Latin America, France and Senegal. It is composed of four packages: Agent, Community, Space and Vegetation-Herd. We illustrate these packages with examples extracted from the various models. The role of this tool is discussed in order to show its advantages and its limits
