ABSTRACT
Groundwater provides an important source of water for ecosystems and humans, especially during droughts (Kløve et al. 2014 a). Increasing use of groundwater has led to groundwater level declines in many part of the world. Reduced groundwater levels have resulted in changes river flow affecting riverine ecology, lakes and wetlands. Besides the changes in quantity, increased pollution from cultivation, households and industry has occurred (Balderacchi et al. 2013). In future management, a complete knowledge of groundwater systems and the influence of land use on the services groundwater provides must be understood. For future planning purposes the impacts of groundwater abstraction and irrigation must be better understood.
