  abstract = {{T}he aim of this study is to propose methods to improve crop and water management in {M}editerranean regions. {A}t landscape scale, there is a spatial variability of agricultural practices, particularly for grasslands irrigated by flooding. {T}hese grasslands are harvested three times per year and produce high quality hay, but their productions decreased significantly during the last few years because of the water scarcity. {I}t is therefore important to assess the real water requirement for crops in order to predict productions in the case of agricultural practice modifications. {U}ntil now, the spatial variability of agricultural practices was obtained through surveys from farmers, but this method was tedious to describe an entire region. {T}hus, the specific aim of the study is to develop and assess a new method based on a crop model for estimating water balance and crop yield constrained by products derived from optical remote sensing data with high spatio-temporal resolution. {A} methodology, based on the combined use of {FORMOSAT}-2 images and the {STICS} crop model, was developed to estimate production, evapotranspiration and drainage of irrigated grasslands in 'the {C}rau' region in the {S}outh {E}astern {F}rance. {N}umerous surveys and ground measurements were performed during an experiment conducted in 2006. {S}imple algorithms were developed to retrieve the dynamic of {L}eaf {A}rea {I}ndex ({LAI}) for each plot and the main agricultural practices such as mowing and irrigation dates. {T}hese variables computed from remote sensing were then used to parameterize {STICS}, applied at region scale to estimate the spatial variability of water budget associated with the biomass productions. {R}esults are displayed at the farm scale. {S}atisfactory results were obtained when compared to ground measurements. {T}he method for the extrapolation to other regions or crops is discussed as regard to data available.},
