The Eastern Tropical Pacific Marine Corridor (CMAR) is an intergovernmental initiative between Colombia, Costa Rica, Ecuador, and Panama. The CMAR area is a vast, irreplaceable, and interconnected marine ecosystem that harbors a wide range of globally significant wildlife such as sharks, whales, and sea turtles, many of which are rare, threatened, or endangered. Since 2004, CMAR countries have partnered on the ecological, economic, and social resiliency of this region. With funding from the GEF, The Pew Charitable Trusts is supporting these countries to consider how best to design and develop a durable finance mechanism that will support their ambitions to enhance ecological connectivity, protect biodiversity, promote well-being and climate resilience, and help maintain a productive ocean-based economy. This Enduring Earth project is facilitated by Pew, with assistance from TNC and WWF.
