Water scarcity is one of the main factors limiting agricultural development in semi-arid areas. Remote sensing has long been used as an input for crop water balance monitoring. The increasing availability high resolution repetitivity remote (forthcoming Sentinel-2 mission) offers unprecedented opportunity to improve this In study, regional consumption was estimated with SAMIR software (SAtellite Monitoring IRrigation) using FAO-56 dual coefficient model fed NDVI image time series providing...
Abstract. In semiarid areas, agricultural production is restricted by water availability; hence, efficient management a major issue. The design of tools providing regional estimates evapotranspiration (ET), one the most relevant balance fluxes, may help sustainable resources. Remote sensing provides periodic data about actual vegetation temporal dynamics (through normalized difference index, NDVI) and availability under stress surface temperature Tsurf), which are crucial factors controlling...
This article aims to estimate the water footprint (WF) of cereals—specifically, wheat and barley—in Kairouan plain, located in central Tunisia. To achieve this objective, two components must be determined: actual evapotranspiration (ETa) crop yield. The study covers three growing seasons from 2010 2013. ETa estimation employed S-SEBI (simplified surface energy balance index) model, utilizing Landsat 7 8 optical thermal infrared spectral bands. For yield estimation, an empirical model based...
Abstract. EvapoTranspiration (ET) is an important component of the water cycle, especially in semi-arid lands. Its quantification crucial for a sustainable management scarce resources. A way to quantify ET exploit available surface temperature data from remote sensing as signature energy balance, including latent heat flux. Remotely sensed balance models enable estimate stress levels and, turn, status most continental surfaces. The evaporation and transpiration components are also just...

The aim of this paper was to demonstrate the potential multi-temporal X-band Synthetic Aperture Radar (SAR) moisture products be used for calibration a model reproducing soil (SM) variations. We propose MHYSAN (Modele de bilan HYdrique des Sols Agricoles Nus) simulating water balance bare soils. This simulate surface evaporation fluxes and content (SMC) at daily time scale over semi-arid, agricultural site in Tunisia (North Africa). calibrated using seven very high-resolution SAR...
The increasing availability of high resolution repetitively VIS-NIR remote sensing, like the forthcoming Sentinel-2 mission to be launched in 2015, offers unprecedented opportunity improve agricultural monitoring. In this study, regional evapotranspiration and crop water consumption were estimated over an irrigated area located Kairouan plain (central Tunisia) using FAO-56 dual coefficient balance model combined with NDVI image time series providing estimates actual basal (Kcb) vegetation...
