Abstract:
The present research focuses on the drivers of groundwater use and the impact of groundwater overexploitation on users. It takes a limited geographic area of the Upper Litani River Basin identified with an important water table drawdown. It traces back the evolution of groundwater use in space and time since the 1960s, with a focus on irrigation supply based on interviews with farmers, mayors and municipal officials and other informants, as well as on a literature review, compilation of well data and direct field observations. It also looks at the institutional framework of groundwater management and its problems based on a literature review and interviews with state officials. The unpacking of drivers and impacts of groundwater overexploitation in each of the seven studied subareas in the study zone revealed clear interrelations, both between the users of the same sub-area and between users of the different sub-areas: This creates a complex system of interrelated water uses, where reducing groundwater overexploitation and balancing its negative impacts among the different users requires the integrated understanding and management of surface and groundwater resources. Looking at the management strategies developed by users on the one hand, and by the different water authorities on the other, reveals many obstacles to establishing and enforcing appropriate and coordinated allocations from both surface and groundwater. This reveals that substantial challenges pertaining to water planning are to be faced by the state in the upcoming years.
