“…This software runs on the Sponge JS modeling platform [30]; at different scales, from the farm scale, using individual farm operating data, up to the regional scale water flow can be systematically quantified. Using the modeling software AgroHyd Farmmodel, water flows can be modeled and systematically quantified at different scales, from the farm scale (Brazilian broiler farms [31]), to the regional scale (feeding rations in Brandenburg [32]; Irrigation water demand in Germany [33,34]). Data from different sources (local climate, crop, soil, and farm data) are combined in modeling units to provide detailed modeling of the local hydrological processes.…”

“…For calibration purposes of the AgroHyd Farmmodel single water flow components were analyzed by comparing model results to measured values for actual evapotranspiration based on lysimeter measurements in the Weimar region in Thuringia (Central Germany) for the crops spring barley, winter wheat, and potato [36], and in Hesse (Central Germany) for oat [37]. The calibration results can be seen in [33,34]. To the knowledge of the authors for the calibration of the water flows in wine production no lysimeter measurements were available.…”

Abstract:The German wine sector has encountered new challenges in water management recently. To manage water resources responsibly, it is necessary to understand the relationship between the input of water and the output of wine, in terms of quantity and quality. The objectives of this study are to examine water use at the farm scale at three German wineries in Rhenish Hesse, and to develop and apply, for the first time, a quality-based indicator. Water use is analyzed in terms of wine production and wine-making over three years. After the spatial and temporal boundaries of the wineries and the water flows are defined, the farm water productivity indicator is calculated to assess water use at the winery scale. Farm water productivity is calculated using the AgroHyd Farmmodel modeling software. Average productivity on a quantity basis is 3.91 L wine per m 3 of water. Productivity on a quality basis is 329.24 Oechsle per m 3 of water. Water input from transpiration for wine production accounts for 99.4%-99.7% of total water input in the wineries, and, because irrigation is not used, precipitation is the sole source of transpired water. Future studies should use both quality-based and mass-based indicators of productivity.

“…The water demand of crops is mainly covered by precipitation and only 1% of the water abstraction from ground-and surface water is used by agriculture (Drastig et al, 2016). In recent decades, however, land use has been moving towards more water-demanding crops (Drastig et al, 2016). Actual irrigation took place on 13 700 farms over 3656 km 2 , which makes up only 2% of the utilized agricultural area of Germany and 1% of the total land surface.…”

“…In Germany, water use in the irrigation sector is relatively low. The water demand of crops is mainly covered by precipitation and only 1% of the water abstraction from ground-and surface water is used by agriculture (Drastig et al, 2016). Based on the German national survey (Statistisches Bundesamt, 2014), the irrigable area in Germany was 6913 km 2 , encompassing 19 700 farms.…”

In Germany, the irrigation sector accounts for only 1% of water use. In recent years, however, this sector has attracted more attention due to the occurrence of severe drought periods. Irrigation scheduling systems could support adaptation strategies but little is known about current providers, performance and users. In this study we aimed to depict the current situation of the existence and functioning of irrigation scheduling systems available in Germany. Six methods were identified and assessed based on direct interviews with end‐users and a comparative analysis. The results showed a positive feedback from the users. However, the recommendations were rarely implemented, while only the seasonal irrigation requirement was considered to support actual water abstraction. These results were corroborated by the comparative analysis. Five of the six irrigation scheduling systems estimated the seasonal irrigation amount consistently, while wider differences were found by looking at the irrigation season and at the number of irrigations. Overall, it is found that irrigation support systems are valuable tools for supporting adaptation strategies to fast changes in agro‐environmental conditions. However, specific assessments based on real measurements should be considered in order to improve the performance of the systems and provide more consistent support to end‐users. © 2019 John Wiley & Sons, Ltd.
