What are nature-based solutions? Are they different from green infrastructure?

A handful of terms are used to describe the utilization of natural features, systems, and landscapes to solve many of today’s environmental challenges, including nature-based solutions and green infrastructure. While these ideas and terms are gaining popularity and traction, confusion over the specific structures and systems the terms refer to may limit understanding of their potential impact. Some of the most commonly used terms are nature-based solutions, nature-based infrastructure, natural infrastructure, green infrastructure, blue infrastructure, and blue-green infrastructure.The definitions of these terms vary:

  • Nature-based infrastructure or nature-based solutions (NbS) do not have a universal definition, but organizations generally interpret NbS as solutions that utilize natural or modified ecosystems and provide societal, human, environmental, and economic benefits.1 NbS are “designed to address major societal challenges, such as food security, climate change, water security, human health, disaster risk, social and economic development."
  • Natural infrastructure generally refers to the protection or restoration of natural ecosystems, working landscapes, and other open spaces (such as wetlands, floodplains, and forests) to solve environmental challenges.3
  • Green infrastructure often describes infrastructure features that mix vegetated and engineered elements to filter, absorb, and slow stormwater.

There are numerous ways that philanthropy and NGOs can support engagement around nature-based solutions at various scales, from local to global. Example entry points include:

  1. Elevate policymaker awareness around public health and environmental justice benefits of nature-based solutions, which includes improving coastal water quality, increasing green space, and potential job creation (e.g., building constructed wetlands and urban gardens).
  2. Advocate for public and private investment in stormwater reduction solutions (including through green infrastructure and nature-based solutions) to reduce combined sewer overflows and increase coastal resilience to flooding and pollution events.
  3. Support scientific research and capacity building to integrate blue carbon in climate mitigation, adaptation, and resilience commitments.
  4. Advocate for inclusive and equitable policy agreements and processes that recognize the rights and participation of Indigenous peoples and local communities in the context of climate action.
