In this study, we present an operational methodology for mapping irrigated areas at plot scale, which overcomes the limitation of terrain data availability, using Sentinel-1 (S1) C-band SAR (synthetic-aperture radar) and Sentinel-2 (S2) optical time series. The method was performed over a study site located near Orléans city of north-central France...
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 ...
The objective of this paper is to present an approach for mapping irrigated areas at plot scale using the Sentinel-1 radar time series. Over a study site located in Catalonia region of north Spain, a dense temporal series of Si backscattering coefficients were first obtained at plot scale and grid scale (10km x 10km). The S1 time series at plot and...
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...
The recently launched Sentinel-1 satellite with a Synthetic Aperture Radar (SAR) sensor onboard offers a powerful tool for irrigation monitoring under various weather conditions, with high spatial and temporal resolution. This research discusses the potential of different metrics calculated from the Sentinel-1 time series for mapping irrigated fiel...
Dans le monde de l'irrigation, la région de Marrakech est connue pour l'ancienneté et la complexité de réseaux de canaux de surface, les seguias, alimentés par les oueds du Haut Atlas et de réseaux de galeries drainantes, les khettaras, qui ramènent en surface les eaux de la nappe phréatique. Dans les années 1970, la gestion de ces ouvrages hydraul...

In no other country, perhaps, is the identification between water, irrigation, and agriculture as strong as in Egypt. Several phases of agrarian and technical change throughout its long history have taken Egypt to a situation where farmers grow between one to three crops a year on 3.78 million ha after lifting water from canals and drains, and some...
Depuis une dizaine d'années, le Maroc a engagé un plan ambitieux d'investissements dans le domaine de l'agriculture. Dans un contexte où le potentiel de mobilisation de ressources supplémentaires est marginal et où le déstockage annuel des nappes est de l'ordre d'un milliard de m3, l'expansion et l'intensification de la production agricole irriguée...
