This handbook identifies principles and policy mechanisms to advance community-based learning for sustainable development based on the commitments endorsed by the participants of the Kominkan-CLC International Conference on Education for Sustainable Development, which was in Okayama City, Japan, in October 2014. To inform policymakers and practitioners new to this field, the handbook clarifies the international vision and goals for sustainable development and Education for Sustainable Development, and identifies the potential contributions of community-based learning centres and organizations. It documents both policy and practice from different regions and concludes with a summary of principles and policy support mechanisms.
