The Muga Valley is situated in the North East of Spain, in a 100,000 hectare watershed north of Barcelona. The Muga Watershed is part of a bigger bioregion with three other watersheds: the Fluvia, the Ter, and the Tordera. Together, they form the main source-to-sea water system for the Costa Brava. This bioregion is the working area of the Pioneers of our Time Foundation. The Muga Valley is our home and laboratory, and the Muga Basin is our community of 68 municipalities with whom we collaborate.
