Drought is often associated with crisis. Drought may, however, also be analyzed as a disruption of conventional routines enabling actors to innovate herding techniques and alter existing power structures as in northern Senegal, where pastoral migration acted as a catalyst for technological innovation. The book focuses on the changes in access and control over water and pastures triggered by post-drought population movements and explores the micro-politics surrounding the allocation of grazing lands and watering and the changing configurations of power which have ensued.
