Pilot River Basin - Envrotas: Overview of EnviFriendly (LIFE05 ENV/GR/000245)

What we want to restore and what to avoid... The situation today….. What we have found… What we want to restore and what to avoid...

More specifically...

How….. 1. The demonstration of a “toolbox” of environmental friendly technologies for the minimization of non-point source pollution from agricultural lands and 2. The integration of their design in the watershed management plan of the Evrotas river basin and its coastal zone.

What’s new….. 1. Environmental measures have been focusing at load reductions and farm practices 2. New Approach focusing at the interfaces (Greek loads have already been reduced substantially) 2. Low cost technologies that can be implemented by the farmers themselves.

Demonstration of EnviFriendly Technologies 1. Monitored Natural Attenuation 2. Management of Drainage Canals and Riparian Zone Phytoremediation 3. Management of Agri-wastes
