Adaptation Strategies for Climate Change and Extreme Weather Conditions and Measures for a Sustainable Groundwater Management (AnKliG)
Topic of the practice
The research project “AnKliG” aimed at the development of adaptation measures and strategies for a sustainable and integrated groundwater management addressing the already existing groundwater-related conflicts between agriculture, forestry, biotopes, residential areas and water supply in the Southern part of Hessen in a cross-sectoral approach.
Good Practice Information
The research project “AnKlig” was set up in co-operation of the Hessian Agency for Environment and Geology, a major water supplier (Hessenwasser) and an engineering company (BGS Umwelt). The project was funded with a budget of 1 Million € by the Federal Ministry of Education and Research (BMBF) and belongs to the national research programme “klimazwei”. Research activities focused on a large porous aquifer in South Hessen (Hessian Reed) and the adjacent fractured aquifer of the Odenwald. The two regions differ considerably in their hydrological regime and water supply infrastructure. The overall aim of the project is to develop adaptation measures and strategies for a sustainable groundwater management. The major objective of the project is to assess the implications of climate change on the various sectors which need to be addressed by an integrated groundwater management approach. Spatially distributed groundwater modelling is carried out to quantify the changes in groundwater
recharge and levels for different emission scenarios (A1B, A2, B1). The used climate projection data are based on the general circulation model ECHAM5 and different regional climate models (WETTREG, STAR, CLM). Furthermore:
- to quantify the future water demand for drinking water and irrigation
- to evaluate the supply guarantee of local facilities for public water use (e.g. springs in the Odenwald region)
- to assess the extent of conflicts of groundwater utilisation with other kind of land use
- to reveal capabilities and limitations of groundwater management to counterbalance the impact of climate change on groundwater resources.
The spatially distributed water balance model (methodolgy) may be applicable to other regions in order to investigate the potential impacts of climate change on groundwater recharge and other water balance components. The experience of assessing & handling uncertainties associated with regional hydrologic impact modelling can be transferred and exchanged.
Evidence of success
The practice was conducted via a multi-level institutional approach: cooperation between an environmental agency, a regional water supply company and an engineering company. The the cross-sectoral research approach, which integrated the vulnerability and needs of different groundwater dependent fields, was also an innovative practice.
