Desertification is a serious threat to human survival and to ecosystems, especially to inland desert oases. An assessment of desertification severity is essential to ensure national sustainable development for agricultural and land expansion pro[...]Article
Climate change, drought, and anthropogenic effects are among the main drivers causing alterations in natural resources one of which is the lake level (LL) of large saline lakes, which are mainly located in arid and semi-arid regions. As an urgen[...]Article
Sesame (Sesamum indicum L.) is one of the most recommended oil crops due to its nutritional and medicinal properties. It is a tropical and subtropical plant; however, it is also cultivated in arid and semi-arid regions, including Morocco. Nevert[...]Article
Olive trees are one of the few alternative crops available for farmers in arid environments. In many of these regions, surface irrigation is increasing. The aim of this study was to estimate the pattern of water soil reserves through the season [...]Article
Article
The water pollution risk is considering a topical subject in Algeria and throughout the world, especially in view of the problems of water scarcity and the climate change phenomena. The infiltration of untreated urban waste into the subsoil pres[...]Article
S. Merdas ; Y. Kouba ; T. Mostephaoui ; Y. Farhi ; H. Chenchouni |Despite many studies that have explored the effect of livestock grazing on plant communities, the response of species composition and diversity to livestock grazing in arid rangelands remains ambiguous. This study examined the effects of livesto[...]Article
Dans le bassin versant de lOued Daoura, la vie oasienne est fondamentalement basée sur lagriculture. Cependant, avec les conditions climatiques difficiles où leau se fait rare, le recours à lirrigation est une priorité. En plus, les besoins [...]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
M. Fetoui ; F. Aribi ; F. Chouikhi ; M. Sghaier ; M. Sghaier |This paper presents a livelihood vulnerability assessment and compares the levels of exposure, sensitivity and adaptation to climate change of the local populations in mountains area and coastal plains in Tunisian arid regions. The United Nation[...]Article
Innovative irrigation techniques should be implemented to improve irrigation management in dryland countries. In this regard, a new scheme, that uses three sets of irrigation depth and numerically simulated cumulative transpiration, was evaluate[...]Article
Conservation agriculture (CA) involving zero tillage, crop diversification, and residue retention is considered a panacea for several interrelated problems in agricultural production. However, in the mixed crop-livestock production systems of th[...]Article
M. Al-Saidi ; P. Das ; I. Saadaoui |The circular economy concept can enhance sustainability through restructuring consumption and production patterns using innovative designs and business models. This core premise is highly relevant for the interlinked water and food supply sector[...]Article
R. Ikkou ; H. Lazhar ; Y. Benbrahim |La forêt d'Itzer s'inscrit dans le cadre géographique du versant Sud du Moyen Atlas Plissé, région où la dégradation de la couverture végétale est terriblement présente. L'utilisation de limagerie satellitaire (Landsat) nous a permis davoir un[...]Article
Zero tillage (ZT) is recommended for dryland farming because it enhances retention of residual soil moisture. However, it is not always clear whether this translates to an economic advantage over conventional tillage, which helps in controlling [...]Article
This paper briefly describes the contribution of the Foggara to the development of the oases of the Algerian Sahara during more than 20 centuries of exploitation. Over a 20-year period of study in the Touat and Gourara regions (2000-2020), we le[...]Article
Agriculture is one of the most important sectors in the world. It provides food for the growing world populations while also creating employment opportunities. This sector, however, is greatly threatened by climate change, increased water scarci[...]Article
Global drylands comprise over 40% of the earths land surface, support millions of pastoralists and account for half of the worlds livestock. Climate change and socio-economic drivers are rapidly altering dryland social-ecological systems, with[...]Article
A. Smanis ; D. Fuentes ; P. Fuente ; A. Valdecantos |Drylands functioning depends on water fluxes and the retention of resources. The restoration of degraded areas should mimic the natural arrangement of vegetation in the landscape in a source-sink pattern. Reintroducing key woody seedlings throug[...]Article
De nombreuses techniques d'estimation du rendement des cultures sont utilisées. La plus efficace repose sur l'utilisation de données géo spatiales et de technologies telles que la télédétection, notamment dans des conditions de la présente étude[...]Article
V. Alary ; M.E. Caulfield ; L. Amsidder ; X. Juanes ; I. Boujenane ; M.T. Sraïri ; A. Sam ; J. Hammond ; M. van Wijk |A large proportion of rural households, particularly in the dry land areas, representative for more than 10% of the world's land surface and up to 80% in Morocco, depend for their livelihoods on livestock. They exploit livestock's capacity to li[...]Article
Drought is among the highest-impact natural hazards affecting drylands around the world in a warming climate. The Mediterranean region, including Tunisia, is projected to experience the most predominant drying trends worldwide. However, a detail[...]Article
H. Zeng ; H. Zeng ; B. Wu ; M. Zhang ; N. Zhang ; A. Elnashar ; L. Zhu ; W. Zhu ; F. Wu ; N. Yan ; W. Liu |This review describes the latest progress of dryland ecosystem dynamic change in the Mediterranean region. Recent findings indicate that extent of dryland in the Mediterranean region has been expanding in the past decades and will continue to ex[...]Article

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
Regenerative agriculture (RA) is gaining increasing recognition as a plausible solution to restore degraded agroecosystems. In Mediterranean drylands, RA is at incipient state of development and has been limitedly adopted by farmers, partly due [...]
