Nature for People

The challenge: Many people lack access to, and information about, the Bay Area’s natural places and the solutions they provide to build more climate resilience in ways that benefit ecosystems and communities equitably.

The solution: Greenbelt Alliance is deepening the connection between humans and the natural world so that communities can leverage nature’s many benefits to steward the greenspaces and lands that are critical to thrive. Here’s how…



Greenbelt Alliance will provide free, guided walks and hikes as a unique and engaging way to learn about the natural benefits of the Bay Area. Our team of expert outing leaders include urban planners, docents, and naturalists all knowledgeable in the region’s policy landscape, land-use issues, ecology, and history.

Through outings and other learning opportunities like workshops and trainings, a deeper connection to our natural lands is established, driving the will to protect and steward these places for generations to come.


Greenbelt Alliance will drive local advocacy efforts to stop development on lands that contain resources needed to adapt to climate change. We will further policies that advance new development within existing cities. We will amplify initiatives that preserve open spaces and promote urban greening opportunities.

By building community will, the right decisions will be made when it comes to protecting the lands we must rely on to build resilience to climate change. As a result, everyone will have access to nature and its multitude of benefits.


Greenbelt Alliance will focus on places that are being deeply affected by climate hazards. Through our Bay Area Resilience Hotspot initiative, we have identified communities that need our help the most and will collaborate with decision makers, community leaders, and residents to leverage nature to adapt.

Doing things like planting trees for shade, converting schoolyards into greenspaces, and creating resilience hubs for refuge will allow for at-risk residents to not only survive, but thrive during climate events like extreme heat.
