The International Conferences on Community Based Adaptation (CBA) to climate change


Building a local-to-global CBA community

In January 2005, the first international conference on Community-Based Adaptation (CBA1) convened with more than 80 experts, policymakers, NGO representatives and grassroots practitioners, in Dhaka, Bangladesh. This was initiated in partnership between the International Institute of Environment and Development (IIED), the Bangladesh Centre for Advanced Studies (BCAS), the Regional and International Networking Group (RING) Alliance of Policy and Research Organisations.

Since then (as of April 2019), thirteen international CBA conferences have been held in eight different countries in Asia and Africa. Keynote speakers have included Nobel Peace Prize winner Muhammad Yunus (CBA3), Louise Chamberland UNDP, Bangladesh Prime Minister Sheikh Hasina (CBA5), then Executive Secretary of UNFCCC Christiana Figueres, Margareta Wahlstrom, Special Representative of the UN Secretary General for Disaster Risk Reduction, and Atiq Rahman of BCAS, among many illustrious speakers.
