There is no simple understanding of crop and livestock farmers' response in the Sahel to rainfall variability. Nielsen and Reenberg  developed human-environment timelines for the period 1950-2008 for a small village in northern Burkina Faso, relating livelihood diversification and crop-livestock management changes that map closely to local rainfall variability, such as fields abandoned in dry years and intense animal manure use in wet years. Although they found a significant correlation between crop-livestock management practice changes and major climatic events, the climate is only one of many interacting factors that influence local adaptation strategies . Robust attribution of observed changes to specific change drivers remains a challenge.
