    This study attempted to predict the likely impacts of a dam reservoir and flow regulation on riparian plant composition and diversity. The study was conducted around the Koga dam in the upper part of the Blue Nile basin in the northwestern part of Ethiopia. Floristic composition and diversity in the riverine and adjacent sites of the river was studied. The presence of plant species that would be affected by the storage of the Koga River water and the modification of the downstream river flow regime were assessed.

    The design of public policy related to irrigation sectors in North Africa was often based on the state view. Local farmers' organizations, made up of family farms, did not contribute to building the legal framework, which was in turn unable to propose specific solutions for family farming. Legal reforms currently underway in Morocco and Algeria show how difficult it is to integrate field realities. Access to land and water resources is often obtained through informal local coordination modes.

    Changes in soil texture, bulk density, pH, concentrations and stocks of OC, N, P and K before and after conversion of a 6-year-old Acacia senegal plantation to other land management systems (LMS) were investigated, after three cropping seasons, in the drylands of western Sudan. LMS included pure and intercropped sorghum (PS), roselle (PR) and grasses (PG) with A. senegal at high- and low-tree densities (HD 433 and LD 266 trees ha-1).
