Implementation of Integrated Water Resources Management in Oases

The ecological and hydrological situation in the Beni Abbès Oasis was characterised by an overexploitation of the groundwater resources and a corresponding water scarcity. This was amongst others due to a non existing integrated water resources management strategy and changing climate conditions.

Already during the first project phase (2005-2006) a system for integrated water cycle management had been developed on a pilot basis. The model was designed and introduced with the active participation of the population concerned. As priority sectors were identified: drinking water supply, wastewater treatment and irrigation.

Based on the results and experiences made in the first phase, the concept of integrated water resources management was then implemented. The local self-help groups („action committees“) carried out the concepts jointly with the regional and communal institutions (hydraulic authorities, communities). Their tasks comprised among others an improved relationship between customers and the water utility, an increased willingness of the population to pay for water, a better performance of the water utilities, improved water allowances for irrigated agriculture and an increased volume of re-used treated wastewater. Women groups were encouraged to adopt a more active role when implementing the activities. The sensitisation campaigns already started during the first phase ensured acceptance of the measures among the population.
