Impact des aménagements de conservation des eaux et des sols sur la régénération des ressources ligneuses en zone sahélienne et nord soudanienne du Burkina Faso

The aim is to study the impact of soil and water conservation management (SWC) technologies in degraded land recuperation in Sahelian zone. Six agro-pastoral units of project intervention zone are composed with 2 in north sudanian zone (Boundoré and Kabo-Gountouré) and 4 in sahelian zone (Dori North...
