Sharing experience and knowledge from pilot activities amongst practitioners, policymakers, researchers, funders and the communities at risk is essential. With this in mind, the Fourth International Conference on CBA builds on the strengths of the second and third International Conferences on CBA held in Dhaka, Bangladesh, in 2007 and 2009 respectively. The forthcoming conference aims to share and consolidate the latest developments in CBA planning and practice in different sectors and countries in Africa. It will disseminate these lessons learnt at the workshop and through workshop proceedings. Ultimately the aim is to share knowledge and experiences to help those most vulnerable to climate change.
