Water-Saving Agriculture Project in Southern Oasis Area (Tunisia)


Titre : Water-Saving Agriculture Project in Southern Oasis Area (Tunisia)

Pays : Tunisie

Durée : April 2007–December 2016 (117 months)

Southern Tunisia is an arid region with an annual precipitation of 200 mm, and the traditional oasis agriculture (the main product is date palm) using spring water has been performed since ancient times. In recent years, after the springs, the water source, dried up, water in the Continental Intercalaire (fossil ground water at a depth of two to three kilometers) is pumped up and used as irrigation water. Almost 100% of the cultivated land of this region is irrigated where small-scale agriculture is practiced. As the recharge of this fossil ground water is extremely difficult, periodical monitoring is conducted to watch over the volume of exploitation as an attempt to conserve water resources under joint management by Tunisia, Libya and Algeria.
However, the establishment of an efficient irrigation agriculture system that make the most of limited water resources is slow in progress for several reasons such as the leakage of water due to inadequate maintenance and repair of the terminal channels, inadequate control of water supply for irrigation due to a lack of awareness on water-saving, and inefficient water use due to the decrepit intake facilities. As the effective utilization of irrigation water is expected to increase agricultural productivity and conserve water resources, promoting agricultural development while economizing on water in the region is an urgent issue.

Résumé du projet
This project aims to secure stable irrigation water, by developing terminal irrigation and drainage channels in the oases in South Tunisia ; thereby, contributing to an increase in agricultural production and environmental protection through the efficient exploitation of water resources.
