S. Ouda ; T. Noreldin ; J.J. Alarcon ; R. Ragab ; G. Caruso ; A. Sekara ; M.T. Abdelhamid |In many areas of the world, water shortages prevail and threaten food production. Deficit irrigation was commonly investigated in dry areas as a precious and sustainable production approach. Using the CropSyst model to simulate the effects of di[...]Article
Desertification is one of the most important problems facing arid and semi-arid regions, whether it is caused by irresponsible human activity or due to natural conditions or both. The objectives of the study were to assess the environmental sens[...]Article
Food system analysis in arid and semi-arid countries inevitably meets water availability as a major constraining food system driver. Many such countries are net food importers using food subsidy systems, as water resources do not allow national [...]Article
R. Benniou ; H. Tayeb-Bey ; S. Yahiaoui ; C. Tir |En Algérie, comme au Maghreb, les ressources naturelles sont certes diversifiées mais elles demeurent menacées par leffet du changement climatique. Afin de maintenir un minimum de production agricole en cette région, la gestion de leau sous le[...]Article
Le sol représente la couche superficielle, meuble, de la croûte terrestre, résultant de la transformation de la roche mère, enrichie par des apports organiques. Il est à la fois le support et le produit du vivant. Le sol est considéré comme un s[...]Article
Les impacts des changements climatiques auront inévitablement des conséquences importantes, en particulier dans les régions arides et semi-arides où leur vulnérabilité sera exacerbée par les problèmes de sécheresse et le déficit en eau qui vont [...]Article
