Nature-based solutions
Nature-based solutions refer to the use of nature to minimise climate impacts on humans. It also regenerates ecosystems. Natural ways to absorb urban water are about 50% more affordable and 28% more effective than engineered solutions. Some solutions include native tree planting to prevent landslides. While rainwater gardens and retention ponds can also manage floods.
