The OECD's annual Development Co-operation Report provides the most complete analysis of the aid efforts made over the past year and sets out the main lines of action required to build for the future.  This year's edition examines the role development co-operation might play in the face of global economic, political, social and environmental changes as well as how  the implementation of a real global development partnership strategy is coming on and how  this strategy can become the cornerstone of development assistance.
