The CLME+ Project is a 5-year project (2015-2020) implemented by the United Nations Development Programme (UNDP) and co-financed by the Global Environment Facility (GEF). It assists participating countries from two large marine ecosystems (LMEs) in improving the management of their shared Living Marine Resources through an Ecosystem-Based Management approach: the Caribbean Large Marine Ecosystem, the North Brazil Shelf Large Marine Ecosystem.

The combination of those two LMEs is referred to as the CLME+ region, bordered by over 35 States and Territories : the Caribbean & North Brazil Shelf Large Marine Ecosystems. This vast marine area (4.4 million km2) is a major contributor to regional economic development and is key to many globally relevant ecological processes.
