Competence Centre for Climate Change Climate Change Impact Chains in Coastal Areas (ICCA) Final study report The study “Climate Change Impact Chains in Coastal Areas”, produced by the Center for International Forestry Research, CIFOR, was commissioned by the Inventory of Methods for Adaptation to Climate Change (IMACC) project, a global project by the Gesellschaft für Internationale Zusammen arbeit (GIZ) GmbH, and funded through the International Climate Initiative (IKI) of the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU). The project aims at userdriven application and advancement of existing tools and methods for adaptation, developing capacities for adaptation action and supporting SouthtoSouth exchange, particularly among its seven partner countries: Grenada, India, Indonesia, Mexico, Philippines, Tunisia and South Africa. IMACC operates the platform AdaptationCommunity.net that provides intro duction to key topics of adaptation, examples of adaptation experiences and serves as an exchange and webinar platform.
