In Niger, farmers have turned no less than 5 million ha. of the Southern Sahelian provinces Maradi and Zinder green. They protected and assisted spontaneous regeneration of trees in and around their agricultural fields. Between January 12th and 20th, Both ENDS colleague Marie José van der Werff ten Bosch accompanied Chris Reij (CIS, VU University Amsterdam) to the south of Niger, to find out how farmers were able to regreen at such a large scale, and how their experiences can benefit other villages in the Sahel. Both ENDS, VU-CIS and the Centre Régional d'Enseignement Spécialisé en Agriculture (CRESA) have a joint project to spread the approach to the region of Dogondoutchi.
