Objectifs
Identification of the most appropriate demand management strategies for ground water abstraction, where aquifiers are being over-exploited, ensuring sustainable livelihoods of the vulnerable and poor are safeguarded. Poverty reduction strategies for areas where groundwater is being over-exploited.
Groundwater is the principal source of both irrigation and domestic water supplies in many arid and semi-arid countries. However, many of these countries are already consuming more water than is available from renewable resources. In some areas, over-abstraction is leading to saline intrusion and deteriorating water quality. Demand management of groundwater use is required if the aquifers are not to be over-exploited. A variety of measures can be applied to achieve sustainability but their introduction can have very negative impacts on the livelihoods of some sections of the community.
In the irrigation sector, technical solutions (e.g. reducing losses in existing systems ; promoting modern irrigation systems), regulating water use (e.g. water quotas ; crop restrictions ; land-use changes) or introducing market influences (e.g. water tariffs ; water markets) can be considered. In the domestic/municipal water supply sector corresponding technical, allocative and market influences may also be introduced. The poor (vulnerable farming families and domestic consumers) are nearly always adversely affected by the introduction of water demand management measures with poverty increasing as a result. Some groups who are unable to afford the technical solutions for water conservation, are often negatively affected by water quotas and crop restrictions and are unable to meet the cost of water tariffs. The livelihoods of landless and tenant farmer families may become further impoverished by the impact that the introduction of demand management measures has on the actions of their landlords. Strategies are required to ensure that the poor are protected, ones which provide an enabling environment in which the vulnerable can escape from poverty and a climate in which their aspirations can flourish and be met.
