The 2017 Environment and Emergencies Forum took place from Tuesday 26 to Thursday 28 September 2017, and was hosted by UN Environment at the United Nations Office in Nairobi (UNON). Focusing on the topic “From crisis to opportunity: building resilience by managing environmental risk in emergencies”, the event drew upon the Agenda for Humanity, and set the scene for the third United Nations Environment Assembly (UNEA), to be held in Nairobi in December 2017. The Forum centered around three themes: 1) environmental emergency readiness and response; 2) integrating environment in humanitarian response; and 3) the links between environment and conflict. The Forum brought together 165 participants from 52 countries, representing over 100 emergency response, humanitarian and sustainable development organizations.
