The suggested solution consists in the development of a research programme on the impacts of climate change on the French agriculture: Climator. A wide range of institutions is involved, and the programme value a multi-disciplinary approach. One of the priority of the programme was to assess the impact of climate change on French crop production and identify ways for animal breeders to adapt to climate change.

Improving the knowledge of global changes impacts on water resources, and thus identifying whether future water needs could be satisfied, is of fundamental concern to scientists and water managers worldwide. This calls for the development of an interdisciplinary approachaccounting for the specificities and drivers of pressure of specific regions. This interdisciplinary approach can help set up regional adaptation strategies to cope with water stress, as in the efficiency objectives advocated by the MSSD. To support adaptation water management plans and meet users’ needs, more Mediterranean specificities should be taken into account (e.g. industrial water use, dams, tourism) with a more local-scale perspective. This is the subject of ongoing research.

Groundwater in the state of Andhra Pradesh, India is tapped through about 2.2 million wells. The state is largely underlain by hard-rocks, where well-yields are low and determined by thickness of the weathered and fractured zones of the country rock. The rainfall and aquifer characteristics vary within short distances. Additionally, the footprint of food (rice cultivation) on water resulted in depletion of groundwater table. 47% of the state’s area is currently facing water stress. The Central Groundwater Board (CGWB) classified 175 (15.5%) mandals (blocks) as Semi-critical, 77 (7%) as Critical and 219 (19.5%) as Over-exploited out of total 1125 mandals. The state-sponsored legislations, regulating groundwater use, proved to be very difficult to enforce, simply because the number of wells outnumbered the number staff hired by enforcing agencies.
