Impact of agroforestry on land productivity and production systems resilience in drylands of Morocco
M. Elkoudrim ; R. Moussadek ; O. El Ghalmi ; M. Choukri ; O. Kadiri |The arid climatic context of Morocco and the widespread degradation of natural resources constitute the origin of the decline in agricultural production. The challenges generated by this situation encourage the development of innovative and sust[...]
Article
Soil degradation is a short or long ongoing process that limits ecosystem services. Intensive land use, water scarcity, land disturbance, and global climate change have reduced the quality of soils worldwide. This degradation directly threatens [...]
Ouvrage
Les terres désertiques sont-elles l'avenir de l'Égypte ? Celles-ci font l'objet, depuis les années 1950, d'ambitieux projets nationaux, mais aussi de processus plus spontanés de mise en valeur agricole afin d'étendre la superficie des terres cul[...]
Article
The economic effects of global warming have gained considerable attention in the recent economic literature. While the relationship between rainfall and agriculture is well known, precipitations alone do not capture the soil water availability, [...]
Article
To achieve food security goals, water accounting seems to be one of the most powerful tools to deal with water scarcity management. Thus, indicators, such as virtual water and water productivity, can be considered complementary rather than compe[...]

Global and regional interest in the sustainable management of limited freshwater supplies to meet the rapidly increasing population and food dem[...]
Article
In arid and semi-arid regions, agriculture is an important element of the national economy, but this sector is a large consumer of water. In a context of high pressure on water resources, appropriate management is required. In semi-arid, intensi[...]
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 [...]
