Ecosystem-based Adaptation (EbA) is ‘the use of biodiversity and ecosystem services as part of an overall adaptation strategy to help people to adapt to the adverse effects of climate change’ (CBD 2009). The approach was recognised as being cost-effective and generating social, economic, health and cultural co-benefits, (such as impacts on health and well-being, additional sources of income, water purification, carbon storage, pollination, and recreation services) while contributing to the conservation of biodiversity (CBD 2009). In recent years, EbA measures have increasingly been promoted and piloted to help people adapt to climate change and reduce climate-related disaster risk. The current investments in EbA – e.g. by the International Climate Initiative (IKI) of the German Federal Government, the Global Environment Facility (GEF) or the Green Climate Fund (GCF) – and the increasing recognition of the approach as a cost-effective ‘low-regret’ solution in the context of National Adaptation Plan (NAP) processes represents a significant opportunity to promote the uptake of EbA and to mainstream it into general adaptation, disaster risk reduction, and development planning globally.
Climate vulnerability and risk assessments are now widely used as a structured way to identify potential measures as well as most appropriate locations for the implementation of adaptation and disaster risk reduction (DRR) planning at local, national and regional levels.
The Climate Risk Assessment for Ecosystem-based Adaptation Guidebook provides a standardised approach to climate risk assessments in the context of EbAplanning by following the well-established, modular Sourcebook (GIZ 2014) methodology and using an illustrative application example.
