Around the globe, national and regional security is affected by a range of environmental issues.  However, many of these problems can be addressed through shared knowledge and a combined effort.

The Pacific Environmental Security Forum (PESF) is the U.S. Indo-Pacific Command's (USINDOPACOM) program to explore solutions to environmental security issues throughout the Indo-Pacific region.

The primary purpose of the PESF is to increase regional militaries' understanding of these topics and their environmental stewardship obligations, and coordinate efforts with civilian agencies and NGOs for whole-of-government and whole-of-society solutions.
