This article examines the interplay of climate change, demography, and land use in the Sahel. Since the 1970s, recurrent rainfall deficits and a 500,000 km² reduction in arable land have intensified tensions between farmers and herders. Meanwhile, the population has tripled, rising from 40 million in 1970 to 135 million in 2020, and may reach 330 million by 2050. These imbalances have led to increasing instability. The author advocates for a “Green Revolution” tailored to the Sahel, emphasizing energy transitions, agricultural intensification, and demographic policies. In the short term, better irrigation techniques and more intensive livestock practices are critical to restoring sustainable balance.
