It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. Looking beyond the Sahel, the chapters in this book provide case studies from around the world that examine the use and relevance of the desertification concept.

Publication évaluée par des pairsdécembre, 2016Burkina Faso, République centrafricaine, Cameroun, Algérie, Érythrée, Éthiopie, Mali, Mauritanie, Niger, Nigéria, Soudan, Sénégal, Soudan du Sud, TchadAfter 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.

Les études sur la transhumance ont souvent ciblé les pasteurs – notamment peuls – des zones sahéliennes. Pour en donner une autre perspective, la présente étude a été centrée sur les pratiques de la transhumance dans la zone soudano-sahélienne du Mali en intégrant la perception des agriculteurs et des pasteurs sédentaires concernés par la transhumance dans les zones d’accueil. Les scénarios envisageables pour le futur des systèmes pastoraux ont aussi été analysés. Les données ont été collectées à travers des groupes de discussion et des enquêtes individuelles.

Dryland regions in Sub-Saharan Africa are home to one-half of the region’s population and three-quarters of its poor. Poor both in natural resources and in assets and income, the inhabitants of drylands are highly vulnerable to droughts and other shocks. Despite a long history of interventions by governments, development agencies, and civil society organizations, there have been no sustained large-scale successes toward improving the resilience of drylands dwellers.

More than 200 million people living in dryland regions of Sub-Saharan Africa make their living from agriculture. Most are exposed to weather shocks, especially drought, that can decimate their incomes, destroy their assets, and plunge them into a poverty trap from which it is difficult to emerge. Their lack of resilience in the face of these shocks can be attributed in large part to the poor performance of agriculture on which their livelihood depends. Opportunities exist to improve the fortunes of farming households in the drylands.

This paper assesses past trends in agricultural land and labour productivity, as a test whether it is feasible to meet the SDG target 2.3, namely doubling productivity and incomes of smallholders within a 15-year time span, if history were to serve as a guide. The target implies agricultural productivity would need to increase by 4.6% per year on average during 2015-2030. Available country-level data on land productivity (1961-2012) and labour productivity (1980-2012) for 140 countries shows that past trends fall well short of the desired pace of productivity growth.

These guidelines are the result a consultative process that involved a large number of practitioners from both developed and developing countries. Two meetings were held in Glasgow and Delhi and a tentative outline was agreed upon. The guidelines are intended to provide a reference framework for decision makers and planners to adequately plan, design and manage the forest and trees in and around their cities.

The Conference of the Parties (COP) of UNFCCC is a prime opportunity to communicate FAO’s work on climate change and to liaise with potential partners, at the numerous side events and parallel events organized around the COP. This booklet seeks to raise awareness on the impacts of climate change on food security and nutrition and advocate for the importance of having the agricultural sectors properly considered in climate change mechanisms, policies and finances.
