More than 200 multilateral donors receive or serve as a channel for 40% of all aid. To help meet the challenge of ensuring effective and co-ordinated multilateral aid efforts, Multilateral Aid 2010 covers trends in and total use (core and non-core) of the multilateral system, with a special focus on trust funds from the United Nations Development Program (UNDP) and the World Bank. It explores development perspectives of the climate change funding architecture and provides an overview of the response of multilaterals to the financial and economic crisis. While the OECD’s annual Development Co-operation Report serves as a key reference for statistics and analysis on the latest trends in international aid, the Multilateral Aid report – as the name implies – takes a specific look at trends in multilateral aid only.
