Nature-based Solutions (NbS) are defined as “actions to protect, sustainably manage, and restore natural or modified ecosystems, that address societal challenges effectively and adaptively, simultaneously providing human well-being and biodiversity benefits” (IUCN).

Research highlights that NbS could provide around 30% of the cost-effective mitigation needed by 2030 to stabilize warming to below 2°C. They can also provide a powerful defense against the impacts and long-term hazards of climate change, which is the biggest threat to biodiversity. Finding ways to work with ecosystems, rather than relying solely on conventional engineered solutions, can help communities adapt to climate change impacts. Using nature to green cities can also result in significant energy savings and health benefits.
