There is growing recognition that naturebased (or ‘green’) solutions - i.e. the restoration or rehabilitation and protection of natural habitats - when applied strategically and equitably can not only safeguard biodiversity and ecosystem services but also help people adapt to climate change [1,2]. The type of NbS targeted at helping people adapt to the impacts and hazards of climate change is widely referred to as “Ecosystem-based Adaptation” (EbA). The Convention on Biological Diversity (CBD) first formally coined the term EbA, defining it as “the use of biodiversity and ecosystem services ... to help people adapt to the adverse effects of climate change” which “may include sustainable management, conservation and restoration of ecosystems, as part of an overall adaptation strategy that takes into account the multiple social, economic and cultural co-benefits for local communities.”[3] It is often defined as being an alternative to “grey” engineering although really there is a spectrum of interventions which include components of both (i.e. hybrid or “grey-green” approaches).
