Impact of Institutions on the Sustainability of Tunisian Irrigated Areas in the Context of Climate Change
摘要
The purpose of this paper is to analyze the effect of institutional quality on water-use efficiency and sustainability. Hence, we proceed with the estimation of set of different types of indicators (social, economic, institutional and environmental) which have been combined to develop a dashboard for monitoring the irrigated area sustainability. Then, we analyze and explain sustainability of irrigated area. Surveys and field measurements in three irrigated areas from the Kairouan region in central Tunisia are the sources of data used here. Results showed significant differences in the performance levels for the three components of sustainability. Compromise between the three components of sustainability is difficult to achieve in current context of Tunisian irrigated area. Institutional arrangement and organization can be key factors of irrigation water sustainability and farmers welfare.
