PROBLEM OF WATER QUALITY CONTROL
IN THE NIGER BASIN
By M. Ould ALY OUMAR

Niger Basin Authority, Niamey, NIGER REPUBLIC
Since several years the Niger Basin is facing the impacts of the climatic changes and the effect of growing population. This affects the surface and sub-surface waters. The concerned countries have not sufficient means to control the situation except at some urban and rural area.
The Niger Basin Authority in charge of the managment of the water resources is looking forward to solve the problem.

The NBA has engaged since 2002 in a process of Share Vision in view of a Sustainable Development of the basin. One of the major result of this process is the elaboration of a Master plan of the basin. This plan is supported by several partners with the World Bank at the head.
The knowledge on the basin’s water resources in terms of quantity and quality constitute a fundamental element of the Share Vision in the basin development. In this perspectives Canada has already expressed it interest to many of the Share Vision activities and programmes.
The improvement of water quality is a part of its support to the NBA. In a pilot phase it has been considered to:
1) Identify the high pollution risk zone sites of the basin;
2) Evaluate the volume of contamination by toxic substances; (effect on population by consumption of fishes etc..)
This pilot phase will define great actions in pollution control and countries building capacities.
The progressive degradation of the Niger Basin environnement constitutes a real preoccupation for the NBA and its member countries. This is confirmed by a recent consulting mission of evaluation of water quality. In our ongoing process of Share Vision for a sustainable development, the monitoring of waters in termes of quality and quantity constitutes an important component of the NBA Master Plan that which will be finilised in the biginning of the year 2008. Some donors are fully interested by this issue.
