Project summary

Edit project overview to modify the project summary.

The objective of the proyect was: 1) Stablish sustainable agricultural practiques and 2) Recovery of natural spaces.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

Stablish crops of ecologic rice, regenerate habitats of wetlands enviroments, recover local vegetation and conserve aquatic birds. As a result, new natural spaces have been created and local vegetation and wildlife has recovered.

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 site for people. Furthermore, the installation of ecological rice has improved the enviromental flows.
