ExampleRehabilitating natural water inlets to flood bassins (IFAD) Discharge of Niger
varies strongly with a declining tendency
Former flood basins in the Niger delta have fallen dry
or water retreats too early for agricultural use

Excavating natural influents to allow Niger water to supply water to the basins
Construction of weirs to control return flow from basins and avoid uncontrolled flooding
Negotiation of use rights and obligations with users
Creation of a farmer committee for managing each basin
