Résumé
In arid and semi arid regions of the world irrigation is crucial for agricultural production as it stabilizes the water supply for crops and, hence, prevents extreme fluctuations in production and prices. In the Drâa river basin in southern Morocco agricultural production is highly dependent on irrigation as precipitation rates are not sufficient for crop water requirements. The objective of the thesis is to analyze the economic impact of water use on agriculture for the Middle Drâa river basin. The thesis develops an integrated approach for water management of the six Drâa oases and contributes to the discussion of the impact of climate change and water shortage on the income situation of the farmers in arid regions. At first an introduction to the economics of water management and a methodological background for this study is given. This is followed in Chapter 2 by an analysis of water resources and water management in the Drâa valley. Ground- and surface water use and their interactions constitute a complex system of conjunctive water use between the six oases. Chapter 3 analyses agricultural production which is an important activity in the region. Survey data is used to understand farmer’s production structure and strategies under water scarcity which confirmed that water is the major production constraint.
