Protecting and promoting water and soil resources

Note : this objective favours a partnership approach with IRSTEA and CNRS, among others

  • Analysing the relationship between water supply and demand
  • Integrated hydrology/climate/land-use modelling for agriculture and forestry
  • Measuring change in water use: irrigation, reuse, storage, effectiveness
  • Water and soil quality when hydrological and temperature conditions have been altered, suitability of adaptation strategies
  • Soil biology and dynamics, and major geochemical cycles (carbon, nitrogen, phosphorus) under the joint effects of climate change and adaptation of agricultural practices
  • Trade-offs between carbon storage, climate change adaptation and replacing fossil fuel use in forestry

All ecosystems, agricultural or not, strongly rely on water and soil resources. They must be managed to preserve these fundamental resources. Climate change can frequently interact with agricultural and forestry practices to endanger these resources. However, if properly managed, they should be able to buffer the consequences of extreme climatic events, allowing continued production even under drought conditions. The EA  and EFPA  divisions are dedicated to studying and managing soil resources, water resources and aquatic systems. This research complements that carried out by the SAD  and SAE2  divisions on the best methods for managing water and soil resources at different scales, both specifically in at-risk regions and more generally worldwide. Modelling plays a key role in this work. The MIA  division is specialized in analyzing spatial data and generating models that couple biophysical and resource dynamics. The ACCAF  metaprogramme is also very much involved because water scarcity is a major force driving agricultural and forestry systems to adapt to climate change. Additionally, the GloFoodS  and EcoServ  metaprogrammes are helping accomplish this objective by developing methodologies for evaluating and highlighting functions and services of agricultural and forestry systems at a global scale. Finally, the MEM  metaprogramme is carrying out specific research projects that analyze the role of micro-organisms in biogeochemical cycles and the consequences for water and soil quality.
