Présentation
Namibia is the driest country in sub-Saharan Africa and has been projected to reach an overall water deficit by 2020. Southern Namibia is especially arid, and appropriate and holistic management of water resources is thus becoming increasingly essential. Water demand management (WDM) is a potential component of sustainable integrated water resource management in southern Namibia. WDM is a multi-faceted concept that aims to reduce water consumption by directly influencing user demand for water, thereby providing an alternative to costly supply-side management. A contextual review of WDM including its current application in Namibia, focused on recent developments regarding policy formulation, legislation and institutional arrangements. WDM is an important component of the news National Water Policy of Namibia. Surface water In southern Namibia is very limited and the region is largely dependent on groundwater. However large quantities of surface water are used for irrigation and mining. Current water management in the region is disparate and involves several different institutions, and the use of water varies greatly between different economic sectors. Southern Namibia presents a specific set of circumstance for the application of WDM. Each sector has different constraints and opportunities for WDM and the importance of a context-appropriate approach to the adoption and implementation of WDM is emphasized. The strategic objectives of water resource management can also significantly affect the application of WDM.
