According to the International Union for Conservation of Nature, "nature-based solutions harness nature and the power of healthy ecosystems to protect people, optimize infrastructure and ensure a stable and biodiverse future." These solutions play a significant role in mitigating climate change and are estimated to generate more than 30 % of emissions reductions needed to limit global warming. In addition, they play a key role in addressing biodiversity loss, restoring natural habitats and supporting communities to adapt by improving health and socio-economic conditions.
