This guide emphasizes empowering local agents through experiential learning with peers from their own and other countries, by following a strategic, results-oriented approach to learning based on the World Bank institute's capacity development and results framework. This edition contains a full revision of the original art of knowledge exchange as well as new chapters on implementation and results. It draws lessons from over 100 exchanges financed by the World Bank South-South Facility, analytical work conducted by the World Bank Institute and the Task Team for South-South Cooperation, and reflects the experiences of dozens of World Bank Group staff, learning professionals, government officials, and other international development practitioners who have brokered and participated in South-South knowledge exchange activities.
