The 2011/2012 Sahel Drought Emergency was large in scale and geographic scope. Within this scenario, ACF did not just mobilise a response in each of the affected Sahelian countries where it has an operational presence (Mauritania, Mali, Niger, Burkina Faso and Chad) but rather did so within a regional strategic framework that sought to align its response as closely as possible to the dynamics that evolve from pro-active anticipation, to actual response, and on to initiatives that would reinforce the resilience of beneficiaries to withstand and mitigate future food security shocks.
