The World Conservation Congress (WCC), one of the world’s largest environmental gatherings, is convened every four years under the auspices of the International Union for Conservation of Nature (IUCN) to find collaborative solutions to conserve global biodiversity and ecosystems, and harness the solutions nature offers to global development challenges. The WCC convenes in Honolulu, Hawai’i from 1–10 September 2016. The congress will include the IUCN’s 1,300 member organisations from across 161 countries, all seeking to develop the conservation and governance responses necessary to tackle the drivers of biodiversity loss. At the WCC, IUCN members representing government, the private sector and civil society will vote on motions and resolutions that lay out the global conservation agenda for the next four years. The 100 proposed motions are aligned with the overarching objectives of valuing and conserving nature, ensuring the effective and equitable governance of its use, and deploying nature-based solutions to global challenges in climate, food and development.
