The United Nations Environment Program is highlighting the battle by Iraqi forces to reclaim Mosul from the Islamic State as the latest instance in the complex but very real linkage between military conflicts around the world and extreme environmental degradation.

A traditional conservation approach to climate change (e.g., habitat restoration, species protection) has been a primary tenet of the International Union for Conservation of Nature (IUCN) agenda for decades. But this fall at the quadrennial World Conservation Congress in Hawai’i there were new discussions about tackling climate change in the context of national security and environmental peacebuilding.

When Lake Poopó, Bolivia’s second-largest lake, dried up last December, an entire community lost their way of life and the scientific community cast their eyes to the map asking, where next? They didn’t have to look far. According to a report prepared by the World Lake Vision Committee, a collaboration between the International Lake Committee Foundation, the Shiga Prefectural Government of Japan, and the United Nations Environment Program, there are very few major lake systems that are not experiencing decreasing water quality, volume, biodiversity, or some combination of the three.
