On 5 November 2001, the UN General Assembly declared 6 November of each year as the International Day for Preventing the Exploitation of the Environment in War and Armed Conflict. The United Nations Environment Programme (UNEP) has found that over the last 60 years, at least 40 percent of all internal conflicts have been linked to the exploitation of natural resources. The United Nations attaches great importance to ensuring that action on the environment is part of conflict prevention, peacekeeping and peacebuilding strategies – because there can be no durable peace if the natural resources that sustain livelihoods and ecosystems are destroyed.
