The book discusses different ways to improve agriculture and natural resource management by focusing on learning and collaboration. It explores four approaches - Adaptive Collaborative Management, Participatory Action Research, Social Learning, and Innovation Systems - that help deal with the complexity of natural resource systems. Case studies from Bangladesh, Ecuador, Nepal, and Zimbabwe show how these approaches were used in various contexts like farmer field schools and community forestry to promote collaboration and innovation. The book provides practical methods for combining different types of knowledge to create new ideas and put research into action.
