Analyse typologique et performance productive de la culture du blé dur irrigué en Tunisie
Published in Cahiers Agricultures
En Tunisie, la culture de blé dur en irrigué est pratiquée sur une superficie moyenne annuelle de 48 700 ha, soit environ les deux tiers des superficies céréalières conduites en irrigué. Elle produit en moyenne 180 000 t, soit 20 % de la production nationale de blé dur. Cependant, les rendements réalisés restent toujours en dessous des attentes ave...
Near Real-Time Irrigation Detection at Plot Scale Using Sentinel-1 Data
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...
Mapping Irrigated Areas Using Sentinel-1 Time Series in Catalonia, Spain
Mapping irrigated plots is essential for better water resource management. Today, the free and open access Sentinel-1 (S1) and Sentinel-2 (S2) data with high revisit time offers a powerful tool for irrigation mapping at plot scale. Up to date, few studies have used S1 and S2 data to provide approaches for mapping irrigated plots. This study propose...
An optimal price for sustainable irrigated agriculture in central-eastern Tunisia
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...
ClimaVista - EToPhy web : un outil pour gérer l'impact des pratiques phytosanitaires agricoles sur la santé de l'applica...
...
L’emploi des produits phytosanitaires pose des problèmes de pollution diffuse et de santé publique. Les plateformes web de gestion des risques agro-climatiques ClimaVista® Agro, dédiée aux grandes cultures (https://agro.climavista.com/), et Wine, dédiée à la vigne (https://vigne.climavista.com/), proposent désormais deux services d’évaluation des r...
Caractérisation spatiale de la vulnérabilité des ressources naturelles et gestion des risques de pollution diffuse liés ...
Face à l’augmentation massive de l’utilisation des produits phytosanitaires en agriculture, et aux conséquences de dégradation des ressources naturelles, les politiques actuelles en France, sont orientées vers des initiatives de diminution de l’usage de ces produits tout en assurant une transition agro-écologique des exploitations agricoles. Malgré...
Evaluation of water resources of the Pyrenees in a context of climate change and adaptation strategies
...
The Pyrenees range is a transboundary region shared by Spain, France and Andorre. As many other mountainregions, it is excedentary in water resources that are used in a much larger area that includes important urbanconcentrations and productive rural areas. This territory is particularly vulnerable to the consequences of climatechange. The PIRAGUA ...
On farm analysis of the effect of the preceding crop on N uptake and grain yield of durum wheat (Triticum durum Desf.) i...
One of the challenges of eco-efficient agriculture is the development of operational farming practices to increase the level of agricultural production, maximize the efficiency of resource use and reduce environmental impacts. Based on the efficiency frontier concept and the decomposition of resource use efficiency, we used a three-quadrant framewo...
Climate, Irrigation, and Land Cover Change Explain Streamflow Trends in Countries Bordering the Northeast Atlantic
...
Attribution of trends in streamflow is complex, but essential, in identifying optimal management options for water resources. Disagreement remains on the relative role of climate change and human factors, including water abstractions and land cover change, in driving change in annual streamflow. We construct a very dense network of gauging stations...
