Project summary

Edit project overview to modify the project summary.


The objectives of the proyect: 1) Recovery of natural habitats and biodiversity in a highly intensified landscape; and 2) Stablish sustainable agricultural practiques

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.


First, farmers began to cultivate ecologic rice and decrease the use of chemical components. Some rice paddies were converted into wetlands with the introduction of Phragmites australis and other techniques works. Furthermore, Iris pseudacorus were installed in the shore of wetlands. So much vegetation recovered and new natural spaces were created.

Lessons learnt

Edit project overview to modify the lessons learnt.


The function of aquatic birds and local vegetation in this environment is very important, they stablish a ecological balance and they can provide a beautiful place to visit. Furthermore, the installation of ecological rice has improved the enviromental flows.

Reasons for river restoration

Mitigation of a pressure
Hydromorphology
Biology Recover local vegetation, provide more habitats for local wildlife
Physico-chemical
Other reasons for the project Decrease the impact of intensive agriculture (rice paddies)


Measures

Structural measures
Bank/bed modifications
Floodplain / River corridor
Planform / Channel pattern
Other
Non-structural measures
Management interventions Habitat improvement through water and vegetation management
Social measures (incl. engagement) Scientific bird banding workshops, activities performed by volunteers, environmental awareness
Other Advice of local farmers
