“…Mediterranean region is particularly sensitive to changes in agricultural practices and land use since it is often subject to extremes climatic hazards (Evans, 2009;Todisco and Vergni, 2008). During these last years, severe drought conditions have reduced the stocks of water and thus have pushed the policymakers to restrict irrigation in some areas, such as in the Crau region, located in the South-Eastern France (Fig.…”

Abstract. The aim of this study is to propose methods to improve crop and water management in Mediterranean regions. At landscape scale, there is a spatial variability of agricultural practices, particularly for grasslands irrigated by flooding. These 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. It is therefore important to assess the real water requirement for crops in order to predict productions in the case of agricultural practice modifications. Until now, the spatial variability of agricultural practices was obtained through surveys from farmers, but this method was tedious to describe an entire region. Thus, 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 Crau" region in the South Eastern France. Numerous surveys and ground measurements were performed during an experiment conducted in 2006. Simple algorithms were developed to retrieve the dynamic of Leaf Area Index (LAI) for each plot and the main agricultural practices such as mowing and irrigation dates. These 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. Results are displayed at the farm Correspondence to: D. Courault (courault@avignon.inra.fr) scale. Satisfactory results were obtained when compared to ground measurements. The method for the extrapolation to other regions or crops is discussed as regard to data available.

This study examined the structure and trends of climate parameters important to winegrape production from 1952 to 2006 in the Alt Penedès, Priorat, and Segrià regions of NE Spain. Average and extreme temperature and precipitation characteristics from 3 stations in the regions were organized into annual, growing season, and phenological growth stage periods and used to assess potential impacts on vineyard and wine quality, and changes in varietal suitability. Results show an overall growing season warming of 1.0 to 2.2°C, with significant increases in heat accumulation indices that are driven mostly by increases in maximum temperature (average Tmax, number of days with Tmax > 90th percentile, and number of days with Tmax > 30°C). Changes in many temperature parameters show moderate to strong relationships with vine and wine parameters in the 3 regions, including earlier phenological events concomitant with warmer growing seasons, higher wine quality with higher ripening diurnal temperature ranges, and reduced production in the warmest vintages. While trends in annual and growing season precipitation were not evident, precipitation during the bloom to véraison period declined significantly for all 3 sites, indicating potential soil moisture stress during this critical growth stage. Shorter-term analysis of crop evapotranspiration (ETc) reveals that the current impact per 1°C of growing season (Apr to Oct) warming is an increase in water demands in the region by 6 to 14%. These observations, combined with climate projections, indicate potential disruption of climate-variety balance, increasing water stress, and challenges in producing quality wines without the adoption of appropriate adaptive measures.

On the other hand, changes in the frequency and distribution of precipitation are expected due to increased rates of the hydrological cycle, likely affecting water supplies for both urban and agricultural uses. In Europe, for example, Karl (1998), Beniston & Tol (1998), Sumner et al. (2001), andLana et al. (2003) showed decreasing rainfall trends or changes in seasonality of precipitation for much of the Mediterranean region. The interannual variability of the Mediterranean climate makes it difficult to assess tendencies in rainfall distribution patterns and potential impacts of climate change. Nevertheless, some recent studies point out significant changes in extreme events such as more frequent and extreme droughts, increases in cool-season precipitation, and warmseason drying (Easterling et al. 2000a,b, Ramos 2001, Sumner et al. 2001, Brunetti et al. 2002, Klein Tank & Können 2003, Ramos & Martínez-Casasnovas 200...

“…In particular, the hypothesis of volume release for Lake Trasimeno can be used as input in the Lake Trasimeno levels model, also for a future period of simulation (see Section 3.2). In summary, the time series on which the two models operate should be hydrologically significant, but essentially they can be independent, according also the results of studies conducted in this basin [40] which don't find significant annual and seasonal rainfall trends. In particular the annual trend is the most important parameter to evaluate the possible influence in reservoir recharge.…”

Lake Trasimeno is a closed lake in Central Italy and in historically its water level has been affected by wide fluctuations mostly depending on the climate. The lake has suffered many water crises due to water scarcity and in recent decades, droughts have also severely affected the economic and environmental situation. The aim of this study was to analyze the possibility of limiting these severe level fluctuations by evaluating of feasible water resource management policies that could also reduce the environmental stress of this area. Therefore, a specific decision support system (DSS) has been developed in order to simulate different scenarios for the entire water system of the Trasimeno area. In particular, the hydrological model implemented in the DSS allowed for the simulation and validation of different management policy hypotheses for the water resource in order to mitigate environmental and water crises for the Lake Trasimeno. Results indicated that it is possible to transfer a certain amount of water from nearby reservoirs without affecting the availability of the resource for specific users. In this way, Lake Trasimeno can benefit both from an increase in water levels in the lake, so a possible better situation in quantitatively and qualitatively.
