Co-Working with Nature in the Kamchia River Basin

The RECONECT Bulgarian Collaborator is affected by pluvial, fluvial, and flash floods (generated by the emergency discharge of local dams), even simultaneously. Local communities fight against floods in every way they can, but their home-grown risk management lacks important elements to be fully operational. This is where RECONECT steps in.

So, which is the area with the highest natural demand for mitigating the flood risk using Nature-based Solutions and where is the RECONECT Area of Focus in the Kamchia River Basin?
