Climate change – a challenge for MCDA?

Climate change is a major challenge of our time, giving rise to impacts that are global in scope and unprecedented in scale. The UNEP sponsored MCA4climate initiative provides a framework to aid governments in preparing climate change mitigation and adaptation strategies. It incorporates a MCDA model which provides a basis for evaluation and prioritisation of potential policy actions. We discuss the process of model development, the challenges to MCDA posed by this ambitious initiative and progress on a project using the framework to explore the adaptation of the agricultural sector in Peru.
