The overarching goal of the BLUEGEM project is to explore the evolutions of groundwater (GW), irrigation, and climate in the Anthropocene (1900-2100), to better understand their coupling, foresee their potential changes, and identify possible social consequences, which are of paramount importance to assess in order to identify sustainable pathways with respect to water resources, food security, biodiversity, and human well-being and socio-economic activities. To this end, the team will combine advanced numerical modeling of biophysical and social systems, as well as participatory methods with stakeholders, to address 3 innovative objectives:
- Establish the fingerprint of groundwater-soil moisture (GW-SM) interactions and irrigation on global and regional climate, water resources, biosphere, and soil carbon pools.
- Provide improved projections of global and regional climate, water resources, biosphere and soil carbon pools, fully taking into account the influence of GW irrigation and GW-SM interactions.
- Integrate local and regional knowledge and expertise as well as socio-economic data to refine the land use and irrigation scenarios used in state-of-the-art climate projections (CMIP6) and to explore pathways for sustainable Critical Zone management.
