Introduction of the Waterharmonica to Solidaridad
The Waterharmonica is an artificial “wetland” developed by Leaf Wageningen. MWF introduced Leaf to Solidaridad, an international organization dedicated to responsible food production, developed a proposal with Leaf, and pitched the project successfully to a well-known Dutch family foundation, asking for financial support.
The Waterharmonica filters and purifies runoff water from coffee plantations, which is a major pollutant of rivers and other water sources. Leaf is collecting the know-how required to combat this type of pollution and will compile a best practice guide addressing both the technical and commercial aspects. The project also includes a funding plan for coffee entrepreneurs.
