Nature based solutions

Nature based solutions work with and enhance nature to restore and protect ecosystems and to help society adapt to the impacts of climate change. Adaptation calls for the increased use of nature based solutions with multiple benefits which at the same time provides for livelihoods, ecosystem life support and community resilience.

Nature based solutions come with a range of various benefits such as:

  • Buffer and protect from for floods and sea level rise
  • Storing water and mitigating drought
  • Livelihoods from ecosystem goods
  • Mitigating heat e.g. providing shade and cooler microclimates
  • Providing human health and well-being
  • Providing for socio-cultural values
  • Providing for biodiversity and ultimate life-support
