Wilderness Foundation Global (WFG) is an international alliance of action-oriented, like-minded organisations which know that wilderness areas have local meaning and global significance, with direct importance to human health, well-being and inspiration. Founding members are Wilderness Foundation Africa, Wilderness Foundation UK, and the WILD Foundation (USA), with the Wilderness Leadership School (KwaZulu Natal, South Africa) as a patron partner.

In addition to the global reach of the programmes of each member, WFG has four main areas of global impact that we founded and directly facilitate:

- The World Wilderness Congress, established in 1977, is the action-centred, collaborative global, public process that produces practical and inspiring conservation results through the convening and facilitating diverse leaders and experts of all ages in science, policy, business, media & communications, traditional communities and life-ways, the arts & humanities, and civil society.

- The Wilderness Conservation Fund expands protected areas and their effective management by the private and public sectors, and by local communities. Special emphasis is given to the establishment of new wilderness protected areas and ecological corridors in global biodiversity hotspots and areas of community and cultural significance.

- The Wilderness Specialist Group of the World Commission on Protected Areas (IUCN) assures the best global wilderness policy and legislation that systematically address the UN's Sustainable Development Goals, safeguards the irreplaceable life support services of wild nature, and provides direct cultural and social benefits to human communities.

- The Survival Revolution is the global campaign for Nature Needs Half! Protecting intact wilderness is the most important, cost-effective, and immediate action we can take to directly address the three biggest threats facing us: climate breakdown, pandemics, and mass extinction of species. Saving wilderness saves massive economic losses, strengthens human health, and increases the strength and resilience of nature to protect and support us. Protecting wilderness is a major public health priority.

WFG is also a founding member of and an active proponent for Nature Needs Half, a science-based, culturally relevant, open-structure public movement to protect and interconnect at least half of the earth's lands and seas for the well-being of all life.
