  • A study on the impact of structures in the Adour river basin

    In the Aquitaine region, Onema recently studied the impact of structures on all migratory species, in terms of both upstream and downstream migrations.

  • Restoring ecological continuity

    On the national level, an initial set of guidelines on the protection and restoration of river continuity was presented to the Green and blue corridor committee for the Grenelle agreement.

  • Limiting the impact of phytosanitary products on water resources

    The Ecophyto 2018 plan targets a 50% reduction in the use of pesticides over the next ten years and the gradual removal from the market of the most dangerous products. Onema has been put in charge of a part of the funding for the plan.

Territorial management of water and restoration of environments

Support territorial planning

To ensure that ecological issues are better taken into account in the territorial implementation of water policies (river-basin planning at the district (RBMP) and sub-basin levels, programmes of measures, major-river plans, Natura 2000 goals documents for sites with aquatic environments, etc.), Onema assists the Water agencies in preparing biological aspects via its technical skills in biology and hydromorphology.

Encourage ecological engineering on the local level

Onema assists in restoration operations for aquatic environments around the country. With the Water agencies, active on the river-basin level, it stimulates the emergence of local project-management capabilities and provides them with help in defining restoration goals and means. Onema also participates in operations to restore carrying capacities for migratory fish, the symbols of the ecological quality of rivers. It provides its know-how on how to improve aquatic environments and restore ecological continuity, and it contributes to evaluating restoration programmes.

Onema also financially supports the water sector in the overseas territories and Corsica. For example, it participates in funding water supply and treatment infrastructure to assist in efforts to modernise the sector.
