The Guiana Shield Facility (GSF) is a multi-donor funding facility for the long-term financing of national and regional activities to conserve ecosystems, protect biodiversity, and to sustain human livelihoods within the Guiana Shield eco-region.

The GSF supports the position that global significance of the Guiana Shield eco-region and its ecosystem services was, is, and will be the rationale for transfers between the international community and those responsible for maintaining the ecological and cultural integrity of the Guiana Shield. So far, the ecological significance has been best documented by the PSW report of April 2002, updated in December 2011. The 2002 PSW exercise served as the scientific basis of the Paramaribo Declaration adopted on 9 April 2002, to guide the further development of the Guiana Shield.
