Water scarcity and shale gas prospects in tunisia—potential impacts of hydraulic fracturing on regional water stress

Abstract

Hydraulic fracturing of shale plays requires large quantities of water and could pollute water resources, which is especially problematic in the water-scarce North African context. This study investigates the potential impacts of fracking on regional water stress in Tunisia by forecasting shale development and water stress for two key regions. To also understand the political economy of shale gas in Tunisia, experts from different backgrounds were interviewed. The results show that fracking could add important volumes to regional water demand, especially in peak drilling years. However, water concerns are of secondary importance to decision-makers, and the promise of economic benefits weighs heavier, increasing the likelihood of shale gas development.
