TL;DR: In this paper, an aggravating deficit between the groundwater consumption and the recharge of groundwater can be observed, which is characterized by two effects: (1) Increasing groundwater consumption, and (2) Decreasing recharge.
Abstract: Groundwater management nowadays is mainly governed by hydrogeological aspects of groundwater occurrences. However, focussing on groundwater as a natural resource of the landscape, there is a deficit in spatial information about the ecological factors influencing the water balance. It becomes more important to assess the ecological role of groundwater in accordance to its quality and quantity as well as to predict risks by changes in the landscape such as lowering groundwater level and nitrate leaching. Due to high spatial diversity in the pattern of land use, relief attributes and soil properties, ecological data have to distinguish different homogeneous site units. Remote sensing data with high resoluted geometry would have the potential to improve the spatial information about landscape and its water balance. In many regions an aggravating deficit between the groundwater consumption and the recharge of groundwater can be observed. This situation is characterized by two effects: (1) Increasing groundwater consumption. (2) Decreasing recharge of groundwater. A higher level of surface sealing can be found in agriculture as well as in urban areas. Evapotranspiration in plant production has increased. By intensification in agriculture plant production has generated more biomass and crop yield. But for every unit of yield and biomass, the plant has to transpirate additional soil water. Therefore, higher intensity in farming is related to higher water consumption by the process of evapotranspiration.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
