Climate change will certainly increase conflicts concerning water use and will require both water eco-efficient management and access to new resources. Farmers will need to prove they are making good use of their withdrawals and respecting the commitments they have made.

In return, they should have secure access to water and be paid for their services (Payment for Environmental Services, PES) and, over time, through the price of their products.

The aim of the project is to design and test a digital service for monitoring and managing the use of water and providing support for eco-efficient irrigation through RSEau. The service will serve as a trusted third party between the different stakeholders: farmers, water managers, land managers, and agro-industrialists.

The RSEau service will provide an interface for the digital tools used by its partners to pilot water management "from the water table to the plot" and guarantee optimal economic, environmental, and social use of water. Its main innovation is to enable dynamic management of the resource, which includes encouraging public and private stakeholders to draw up contracts for water usage when times are normal but also in times of crisis, and to restore local consensus on water resource management.

On a broader level, the project will help build trust among local actors by giving them a more detailed view of the resource and proof of compliance with the commitments made. In return, farmers who irrigate will be paid for their good environmental practices and will secure their access to water.
