Developing climate-smart agriculture to face climate variability in West Africa: challenges and lessons learnt
This paper reviewed the prospects for climate-smart agriculture (CSA) development and promotion in West Africa as well as lessons learnt and challenges with a focus on climate change and variability. It was evident from the literature that West Africa is vulnerable to climate change and variability, on account of its socio-economic and physical characteristics. As climate change and variability persists, the region’s quest to use agriculture as the mainstream opportunity to deliver on set targets of the sustainable development goals will be strongly challenged without appropriate interventions. Adopting CSA seems to be a suitable strategy to achieving food security while also mitigating and adapting to climate-related risks. Among numerous CSA technologies, the review found (1) agroforestry (farmer-managed natural regenerations), soil and water conservation technologies (zai, half-moon, tie/contour ridges, conservation agriculture) and (3) climate information services as highly valued promising options for climate change adaptation and risk management in West Africa. -
Facing climate variability in sub-Saharan Africa: analysis of climate-smart agriculture opportunities to manage climate-related risks
In the literature, a lot of information is available about climate change perceptions and impacts in sub-Saharan Africa. However, there is limited attention in the region to emerging initiatives, technologies and
policies that are tailored to building the adaptive capacity of agricultural systems to climate change and
variability. In this paper, we discuss the prospects for climate-smart agriculture technologies and enabling
policies in dealing with climate change and variability at different sub-regional levels of sub-Saharan Africa to sustain farm productivity and livelihoods of agrarian communities -
Incidences sécuritaires du changement climatique au Sahel : perspectives politiques
Ce document résume et rassemble les conclusions des analyses effectuées au long du projet. Il dégage les principaux enjeux pour les décideurs politiques, des pistes de travaux futurs, les lacunes et incertitudes des connaissances actuelles. Le climat du Sahel s’est toujours caractérisé par l’extrême variabilité saisonnière et décennale des précipitations. Cette dernière est probablement due à des interactions complexes entre plusieurs processus, aucun processus ne semblant pouvoir seul expliquer la variabilité observée. En dépit d’efforts considérables pour déterminer la cause de la longue et grave période de sécheresse qui a sévi à la fin du XXe siècle, la communauté scientifique n’est pas parvenue à un consensus. Ces incertitudes, ainsi que l’importance de la variabilité, rendent particulièrement difficiles les projections climatiques pour le Sahel et sont à l’origine d’importantes divergences entre les projections des différents modèles climatiques.
