La gestion de l'eau en Nouvelle-Calédonie est problématisée différemment selon le foncier sur lequel se trouve la ressource : hors ou sur terres coutumières. Aujourd'hui, la répartition inégale de la ressource en eau sur ce territoire insulaire influe également sur son partage et sa préservation. Comment peut se construire une politique de l'eau pa...
Better management of water consumption and irrigation schedule in irrigated agriculture is essential in order to save water resources, especially at regional scales and under changing climatic conditions. In the context of water management, the aim of this study is to monitor irrigation activities by detecting the irrigation episodes at plot scale ...
In the context of monitoring and assessment of water consumption in the agricultural sector, the objective of this study is to build an operational approach capable of detecting irrigation events at plot scale in a near real-time scenario using Sentinel-1 (S1) data. The proposed approach is a decision tree-based method relying on the change detecti...
Increasing pressures on water resources are causing many countries in Mediterranean to (re)consider various mechanisms to improve water use efficiency for agricultural like Tunisia country. The price mechanism remains the most appropriate instrument to allocate this water resource, but the search for the optimal price of water that reconciles diffe...
Synthesis note. ENPARD South initiative (European Commission)
Ce rapport du ministère français de l’Agriculture et de l’Alimentation porte un regard prospectif sur l’avenir de l’irrigation agricole en France dans un contexte de changement climatique. Il s’appuie sur une série d’études sur le climat (Climator, Climsec, cinquième rapport du GIEC [Groupe d’experts intergouvernemental sur l’évolution du climat]),...
Pour obtenir et maintenir une eau potable qui réponde aux normes, les collectivités locales ont le choix entre deux types d’actions : préventives par la mise en place de périmètres de protection de captages d’eau potable (PPC) ou d’aires d’alimentation de captages (AAC), ou/et curatives qui consistent à traiter les eaux pour satisfaire les exigence...
This paper constructs a dynamic game model to address the following groundwater management problem, where quantity and quality of the water are taken into account. A group of farmers overexploits a groundwater stock and causes excessive pollution. A water agency wishes to regulate the farmers' activity, in order to reach a minimum level of quantity...

Until the 2000s, water resources in Tunisia were managed solely by government bodies without any consultation with water users. At the local level, Commissariats Régionaux de Développement Agricole [Regional Agricultural Development Committees (CRDAs)], which represented the government bodies, managed water resources. The Tunisian Government then d...
