The Third International Workshop on Community-Based Adaptation to Climate Change was held at the Sheraton Hotel in Dhaka, Bangladesh, from 18-24 February 2009. The event was organized jointly by the Bangladesh Centre for Advanced Studies (BCAS), the International Institute for Environment and Development (IIED) and the RING Alliance of Policy Research Organizations. It was cosponsored by the British High Commission in Bangladesh, CARE Bangladesh, Christian Aid UK, the Danish Embassy in Bangladesh, the Food and Agriculture Organization (FAO), Oxfam-GB, Practical Action UK, and WWF UK.The event consisted of three days of field visits to observe community-based adaptation (CBA) initiatives first hand. This was followed by three days of interactive workshop discussions in Dhaka. The aim of the event was to share the latest developments in adaptation planning and practices at different levels and disseminate knowledge among stakeholders, with a view to integrating adaptation into national and international development programmes. More than 140 participants representing governments, non-governmental organizations (NGOs), community-based organizations, research institutions, UN agencies and development organizations participated in the conference, along with grassroots and development practitioners and the media.During the three days of site visits (19-21 February), participants journeyed to six different locations in Bangladesh to observe CBA in action. Locations included: drought-prone areas in the Chapai Nawabgonj District of northwest Bangladesh; flood and river erosion areas in the Gaibandha District, also in northwest Bangladesh; flood and water-logged areas in the Gopalgonj Districts in southcentral Bangladesh; regions prone to increased salinity in the Satkhira District in the southwest coastal region of the country; the coastal Districts of Noakhali and Laksmipur in the southeast; and the southwest Bagherhat District, prone to increased salinity and cyclones.The subsequent three days of workshop discussions in Dhaka were structured around several technical and plenary sessions. The sessions alternated between technical and plenary sessions, and each of these sessions consisted of presentations and discussions on one or more themes relevant to CBA.Reports from the technical sessions were presented in the subsequent plenary session, where panelists made further comments on the themes under discussion. The technical sessions addressed: methods and tools in designing CBA; adaptation measures and practices related to agriculture; women, education and awareness for adaptation; advancing adaptation through communication for development; mainstreaming and partnership for adaptation; disaster and climate change; and urban adaptation. A final technical session was held on scaling-up adaptation, and this was followed by a concluding high-level plenary session attended by the Planning and Finance Ministers of Bangladesh.Participants at the workshop agreed to establish the Global Initiative on Community-Based Adaptation to Climate Change. The Global Initiative will seek to support CBA-related activities by generating and sharing relevant knowledge.
