"Knowledge Gaps in Making an Economic Case for Investing in Nature Based Solutions for Climate Change".
This report is available both in English and French on the IUCN EBA web page. This preliminary rapid assessment is now being followed up with an in-depth analysis in the Philippines and Peru. We aim to have this study available for the Paris COP 21.
Climate change is having increasingly adverse impacts on people and nature. It exacerbates existing environmental threats, poses new risks and impedes our ability to achieve global conservation and development objectives such as the Aichi Biodiversity Targets and the proposed Sustainable Development Goals. Across the globe, initiatives have been established to help communities implement approaches that enable them to adapt to climate change and mitigate its effects.
Ecosystem-based Adaptation (EbA) is one such approach. EbA uses biodiversity and ecosystem services as part of a larger adaptation strategy – an excellent example of a viable nature-based solution. As well as providing climate change adaptation benefits, this approach also contributes to biodiversity conservation and enhances local economies. IUCN has been extensively involved in EbA work, strengthening community resilience and livelihoods in almost 60 countries. This work demonstrates our ongoing commitment to the implementation of nature- based solutions.
The conservation and sustainable development community considers EbA to be a strong method of addressing climate change and its associated challenges. However, there is still a tendency for policy makers to implement traditional engineering solutions for adaptation, rather than investing in EbA. The need for solid data on the cost-effectiveness of this nature-based approach was the driver behind an IUCN study identifying the economic costs and benefits associated with EbA. The lessons learned from this appraisal process will make it easier for policy makers to compare EbA options with engineered solutions. Download English / French
