This paper presents a synthesis of information relating to adaptation to climate change in the context of creating synergy among multilateral environmental agreements (MEAs), which could be useful in the preparation and implementation of national adaptation programmes of action (NAPAs). The paper reviews NAPA proposals and other relevant documents. It also presents relevant existing programmes and projects under the three Rio Conventions, the Global Environment Facility and its implementing agencies, and the United Nations University. The paper concludes with lessons learned and identifies possible action whereby the Least Developed Countries Expert Group can enhance the promotion of synergy among MEAs during the preparation and implementation of NAPAs
