Cost-benefit analysis, as an economic evaluation tool of public or private projects, has evolved significantly in the last 200 years following the developments in terms of economics, namely Environmental Economic, and developments in project analysis and public policy evaluation. Despite numerous and ongoing criticisms both at a theoretical, academic level as well as at a socio-economic, political level, cost-benefit analysis has remained at the center of a growing culture of economic project appraisal within OECD countries and has even won increasing weight and political recognition, particularly in the European Union. In this thesis, we make a historical analysis of the theoretical evolution and practice of cost-benefit analysis, with particular interest in terms of its use in the analysis of strategies and measures for climate change adaptation, presenting alternative methodologies and tools for the economic appraisal of projects and culminating with an innovative proposal for a participatory benefit-cost analysis, a methodology developed and tested in the Cascais case study under an European action-research project.
