Nile water availability is one of the major constraints for agricultural development in Egypt. This study conducts a mixed multiplier analysis, under water and land constraints, to identify the seasonal agricultural activities with high output a[...]Article
The water scarcity in Algeria is a major problem difficult to solve; in addition to a changeable Mediterranean climate, low rainfall and water pollution emphasizes this problem. Oran (west of Algeria) has suffered a long period of lack of water,[...]Article
M. Aoubouazza ; H. Dakkak ; A. Zouahri |Les présents résultats ont été obtenu dans le cadre du projet salinité (INT/5/144) mené par lAIEA et lINRA sur lutilisation durable des terres salines et des eaux souterraines salées pour la production des cultures tolérantes à la salinité da[...]Article
Climate change, water shortages and desertification threaten the economic and environmental sustainability in the Mediterranean. Limited rainfall and higher temperatures put agricultural production, which relies on water availability, in jeopard[...]Article
Nowadays, climate change scenarios predict a rainfall irregularity, which poses the problem of water resources scarcity. The use of unconventional water and in particular treated wastewater in agriculture is one of the adopted remedies. This wor[...]Article
In the first part of this paper, we deal with the sharing of water in the Ziban region. Several soties in the oasis of Chetma were carried out during the period: 2000-2020. Data and information on the water distribution network were collected fr[...]Article
This study examines the water division in the oases of Garta, Sidi Okba, Thouda and Seriana located on the outskirts of Labiod River. For centuries, these oases have been supplied with water by systems of small dams built along the Labiod River.[...]Article
The objective of this study was to measure the efficiency level of Water Users Associations (WUAs) in the coastal oases of Gabès (South-Est of Tunisia) and assessing its main determinants. First, an input-oriented data envelopment analysis (DEA)[...]Article
A. Lyra ; A. Loukas ; P. Sidiropoulos ; G. Tziatzios ; N. Mylopoulos |This study presents an integrated modeling system for the evaluation of the quantity and quality of water resources of coastal agricultural watersheds. The modeling system consists of coupled and interrelated models, including (i) a surface hydr[...]Article
