基于生态系统的适应(EBA)将生物多样性和生态系统服务作为应对气候变化的更大适应战略的一部分。虽然保护和可持续发展界认为环境影响评估是应对气候变化及其相关挑战的有力方法，但政策制定者仍然倾向于实施传统的工程解决方案来适应气候变化，而不是投资于环境影响评估。对这种以自然为基础的方法的成本效益的可靠数据的需要是世界自然保护联盟一项研究背后的驱动力，该研究确定了与EBA相关的经济成本和收益。这项研究审查了哥斯达黎加、印度、墨西哥、秘鲁、菲律宾和坦桑尼亚的项目并评估了现有数据。结果表明，仍然存在广泛的知识差距，还需要进一步的成本效益分析工作和实地证据，以更清楚地展示EBA为气候变化提供的基于自然的解决方案。
Ecosystem-based adaptation (Eba) uses biodiversity and ecosystem services as part of a larger adaptation strategy to climate change. While the conservation and sustainable development community considers EbA to be a strong method of addressing climate change and its associated challenges, there is still a tendency for policy makers to implement traditional engineering solutions for adapation, 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 study reviewed projects and assessed existing data from Costa Rica, India, Mexico, Peru, the Philippines and Tanzania. The results show that there are still extensive knowledge gaps, and that further cost-benefit analysis work and field evidence is required to showcase more clearly the nature-based solutions that EbA offers to climate change.
