Future climate and land-use change impacts on groundwater recharge rates and water quality for water resources

Climate change will affect the water cycle, including changes in precipitation patterns, increasing water temperature, longer dry periods and enhanced vegetation periods, affecting groundwater recharge and quality. In addition, non-climatic drivers such as land-use change and an increasing global population will affect groundwater quantity and quality.
The Future-H2O-project will focus on the question of the future development of groundwater recharge rates and water quality, considering scenarios of climatic drivers and land-use change, based on an analysis using a new global groundwater database, to be developed.
Aims and objectives
The main objectives of the project are:
- To identify sensitive parameters and methods to monitor change conditions in groundwater systems
- To analyse combined non-climatic and climatic impact on the regional water cycle
- To develop a new method to project regional groundwater recharge based on regional climate ensemble simulations
- To develop indices and tools to analyse climate and land use change drivers for groundwater related assessments
- To develop methods to project the water quality in non-monitored areas for water resource assessments based on lithology, climate and land use
