On 16 November 2007, the UN General Assembly adopted resolution A/62/L.12, which declares the period from 2007-2016 as a “decade of recovery and sustainable development” for territories in Belarus, the Russian Federation, and Ukraine that were affected by the 1986 Chernobyl nuclear accident.

The resolution states that the goal of the decade is a return to normal life for affected communities, while noting the daunting challenges that the region still faces. The UN Development Programme has been assigned to draft a unified UN action plan and coordinating the work on the decade.
