Ecosystem-based Adaptation (EbA) is a strategy for adapting to climate change that harnesses nature-based solutions and ecosystem services. Over the past decade, the UN Environment Programme has embraced the practice as a cost-effective and holistic adaptation approach, now supporting more than 50 EbA projects across the world. Combined, these projects have enhanced long-term adaptive capacity in communities, improved livelihoods, reduced climate risks and improved the health of a diverse range of ecosystems. This policy brief summarizes the key lessons from UNEP’s experiences across multiple countries and ecosystems over the past ten years. Learn more about Ecosystem-based Adaptation here.
