Over 2.000.000 inhabitants draw their livelihood from the swampy forests of Lac Tumba
But in excesses…and with unstustainable means.

Major economic Stakes for the RDC Central Africa and Africa

The Waters of the Congo are declining!!

How to deal with these challenges?
Preservation of waters and swampy forests
International Action - Ramsar Convention and other
mecanisms• Insert water and swampy forests among
natural resources that need specific attention from national, regional and international levels.
• Legally recognized by different nations• Delineate sites with multiple purposes• Management plans for each of these
zones• Adopt an international process of
evaluating the execution of those plans
