Er-Raki |Quantification of actual crop evapotranspiration (ETa) over large areas is a critical issue to manage water resources, particularly in semi-arid regions. In this study, four models driven by high resolution remote sensing data were intercompared[...]Article
Middle Eastern, North African countries (MENA), and Central Asian countries are considered the countries most facing water and food scarcity. The current water exploitation indicates that a few countries are overexploiting their water resources [...]Article
G. Mancuso ; M.C.M. Parlato ; S. Lavrnic ; A. Toscano ; F. Valenti |Agriculture is the major water user worldwide and it is expected to be negatively affected by climate change and water scarcity. The use of non-conventional water resources could be the solution to overcome this issue. In fact, treated wastewate[...]Article
Groundwater is a vital water resource for economic, agricultural, and domestic purposes in arid regions. To reduce water scarcity in arid regions, recently, remote sensing and GIS techniques have been successfully applied to predict areas with p[...]Article
Agricultural water appropriation has undergone rapid changes in recent decades, but estimates of global water appropriation have not been updated with the latest data and consistent methods. Documenting these changes is challenging given the het[...]Article
O. El Mountassir ; M. Bahir ; A. Chehbouni ; D. Dhiba ; H. El Jiar |Groundwater is essential for both water supply and environmental conservation, especially in semi-arid and desert areas. Managing groundwater resources requires a thorough understanding of groundwater characteristics and dynamics. The hydrogeoch[...]Article
D. Masseroni ; F. Gangi ; A. Galli ; R. Ceriani ; C. De Gaetani ; C. Gandolfi |Border irrigation is one of the most ancient but, at the same time, still widely applied irrigation methods across the world. Due to the intrinsic characteristics of the method, the water volumes involved are often difficult to measure and this [...]Article
Scarcity of water has emerged as a major problem globally due to climate change and population growth, especially in semi-arid and arid regions. Egypt is currently experiencing serious water challenges due to its limited water resources. The wat[...]Article
F. Chemak ; H. Mazhoud ; Z. Rached ; A. Gara ; R. Rahmeni ; H. Ghannem |In Tunisia, the development of the irrigated cereal sector plays a key role in the mitigation of the fluctuation of the rainfed production and to ensure a minimum of production. However, the archived yields remain under the expected potential pe[...]Article
Potato crops are one of the main sources of income for farmers living in the Bekaa Valley of Lebanon. Given the high sensitivity of potatoes to water stress, water shortages can cause considerable losses in terms of potato yield and quality. To [...]Article
N. Beithou ; A. Qandil ; M.B. Khalid ; J. Horvatinec ; G. Ondrasek |Food security is an essential issue for human survival and civilization. Whenever food–water security is in doubt, the community is negatively affected. Globally, Jordan is the second most water-stressed country, located in an arid, politi[...]Article
Irrigated agriculture accounts for ∼90% of anthropogenic freshwater consumption, is deployed on 22% of cultivated land, and provides 40% of global food production. Expanding irrigation onto currently underperforming rainfed croplands is cr[...]Article

Assessment of groundwater contamination is an efficient means to discover and carry out the demarcation of the more vulnerable zones to pollution from human activities. This study is focused on the plain of El Asnam (Northern Algeria) characteri[...]Article
Water is the most limiting natural resource in many Mediterranean areas of southern Europe, and this, together with the actual scenario of climate change (CC), promotes a framework of uncertainty and creates major challenges concerning the susta[...]Article
The coronavirus disease-2019 (COVID-19) pandemic had a great impact on the agricultural sector, especially in developing countries. In particular, it caused exceptional challenges to small and local-scale farmers. Field questionnaires and interv[...]Article
Groundwater forms the basis for millions of rural and urban livelihoods in the Global South. Its use for irrigation has spurred widespread socio-economic development in various areas but has also led to aquifer overdraft and related socio-enviro[...]Article
N.H. Ajroudi ; B. Dhehibi ; A. Lasram ; H. Dellagi ; A. Frija |This study aims to analyse Tunisian farmers ability to pay (ATP) in a citrus area and propose a penalising price strategy based on the block-pricing process to decrease over-irrigation without affecting farmers incomes. The methodology is base[...]Article
A. Chebil ; R. Soula ; A. Souissi ; B. Bennouna |This study examines the effects of irrigation water use efficiency improvements and citrus price fluctuations on water values in the tree production systems of northeastern Tunisia. It also aims to compare water values with the real price of wat[...]Article
