Summary
This chapter focuses on the work done through the I.N.R.G.R.E.F to collect and analyses available information on water resources in Tunisia and the role of groundwater during drought. It presents the quantity and quality of groundwater resources data and the integration of the drought indicator information with groundwater resources. This chapter is based on review of the evolving situation during the drought years in Tunisia. It aims to raise awareness of the key linkages between groundwater and drought, and to identify appropriate technical and institutional approaches for improving the operational reliability of groundwater and the sustainability of groundwater resources. Droughts are a recurrent characteristic of the Tunisia climate, and in recent years they have become more frequent and more severe, lasting for longer periods. The repeated drought events, combined with the depletion of the aquifers, are causing acute water shortages, affecting the social life of the country, its economy and the environment. Another interaction between groundwater and droughts concerns groundwater storage and aquifer recharge. Groundwater is globally the most common water source for domestic supply and irrigation during the drought season in arid and semi-arid regions. Climate change, drought and desertification are interrelated, but these processes should not be confused or interchangeably referred to if we are to address the complex issues of drought and water management in the Tunisian region on a sound scientific basis.
