The Sahelian countries (CILSS) are among the poorest countries in the world with the most degraded environments. They are also among the countries that are the most vulnerable to the estimated effects of climate change. The study seeks to: 1) identify how and where climate change exacerbates existing vulnerabilities in the Sahel;2) analyze its potential links to conflict and/or migration; 3) assess current policies that address the climate, conflict and migration nexus, and raise awareness, catalyze support; and finally, 4) inform investments to meet emerging climate change adaptation needs.
