About this Companion Climate change adaptation (CCA) and Disaster Risk Reduction (DRR) are corporate priorities for Oxfam GB. This companion is the fifth in a series that covers key topics for programme staff. It aims to support Oxfam’s programme staff to integrate CCA into their work; it provides a theoretical overview of CCA; and it will direct you to additional resources and practical tools. The companion assumes that you already have an understanding of project cycle management within Oxfam, and it should be read alongside the DRR Programme Policy and the CCA Programme Policy Guidelines.
