Causes and Consequences of Groundwater Use on a Tropical Island: Zanzibar, Tanzania.
Groundwater is a very essential resource: its occurrence and quality are a precondition of human welfare and of the persistence of ecosystems. On carbonate tropical islands, groundwater is often entirely recharged by rainfall, and stored in less efficient aquifers that can easily be overused. The possible consequences of overexploitation include the lowering of the groundwater table, land subsidence, deteriorating groundwater quality, and saltwater intrusion (1, 2). For the east cost of Zanzibar, Tanzania, there is some evidence that present water use is less sustainable and might lead to socio-economic problems in the future. In the light of this, the causes and consequences of groundwater abstraction were investigated.
