Sillero |Wheat and rice are two main staple food crops that may suffer from yield losses due to drought episodes that are increasingly impacted by climate change, in addition to new epidemic outbreaks. Sustainable intensification of production will rely [...]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
Previous studies have shown that enhancing adaptive capacity can reduce vulnerability of farmers to water scarcity and improve their resiliency against environmental changes in the Social-Ecological Systems (SES). The present study aims to evalu[...]Article
Les projections du GIEC quant aux fortes tensions à venir sur laccès et le partage de leau interrogent en particulier les voies et les moyens dadaptation de lagriculture dici à 2050. Le ministère de la Transition écologique et solidaire et [...]Article
A rapid method to estimate the different components of the water balance in Mediterranean watersheds
The sustainable management of water resources, whether surface or underground, requires the identification of the flows involved and the possibility of achieving the water balance of the water resource. These require knowledge of the main flow c[...]Article

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
Z. Unnisa ; A. Govind ; M. Marchetti ; B. Lasserre |The ever-increasing water demands in the agricultural sector of the Mediterranean basin region (MBR) under climate change warrants that crop water productivity (WP) is a pertinent topic for discussion. Considering this need, this study aims to s[...]Article
Wetlands constitute important habitats that provide several ecosystem services (ES). Wetlands have been termed the kidneys of the world for their water purification services and contain 2025% of total soil organic carbon. This paper is a review[...]Article
Appropriate irrigation water management has attracted a considerable degree of attention because it is crucial to guarantee water and food security worldwide. A smart irrigation system is applied for the rational use of water in agricultural fie[...]Article
CONTEXT In the Middle Ages, the Muslims introduced communal water management in the Iberian Peninsula. Some irrigation systems of medieval origin are still in operation in the mountainous areas of Southern Spain. Snowmelt runoff is diverted duri[...]Thèse, Mémoire, Master
Le changement climatique et ses effets sur lagriculture soulèvent la question de ladaptation de nos sociétés à ces enjeux. En particulier, au sein de grandes cultures comme celle du blé dur, il convient dexaminer les différentes options dada[...]Article

Agriculture is one of the main sources of diffuse pollution, such as fertilisers, plant protection products, solid particles or pathogens. The short- and long-term impact of agriculture on surface water quality is often driven by on-farm decisio[...]Article
Meteorological drought is defined as the event that arises when precipitation is lower than average and initially affects rainfed crops; this is transformed into hydrological drought when persistent drought affects water storage. We have studied[...]Article
Soil, a non-renewable resource, sustains life on Earth by supporting around 95% of global food production and providing ecosystem services such as biomass production, filtration of contaminants and transfer of mass and energy between spheres. Un[...]Article
