STEW-MAP: The Stewardship Mapping and Assessment Project
Who, what, where, why and how are urban environmental stewardship groups working in New York City?
The Stewardship Mapping and Assessment Project (STEW-MAP) seeks to answer the question: What are the social and spatial (geographic) interactions among people and groups that conserve, manage, monitor, advocate for, and educate the public about their local environments (including water, land, air, waste, toxics, and energy issues)?
Stewardship is one of the ways that both informal and more organized groups contribute to the care of their local environments. These groups work alongside or independent of public agencies and private businesses in managing urban places . STEW-MAP is both a study of New York City’s stewardship network and a publicly available online tool to help support that network.
How was STEW-MAP developed?
The project was developed by a team of Forest Service and university researchers working with dozens of government agencies and environmental nonprofit groups. Early on, project participants identified a need to create a common database of stewardship groups and a citywide map of stewarded sites. To date, New York City’s STEW-MAP has collected information from nearly 5,000 local citizen groups that range from informal block associations and kayak clubs, to tree planting groups and formal nonprofit organizations. A network analysis of these groups highlights the connections between civic environmental groups and identifies key stewardship nodes (those groups that work with many different partners) within the network. STEW-MAP’s publicly available online map currently displays spatial (geographic) data for over 500 stewardship groups citywide alongside other open space data layers. The project adds a social layer of information to urban geographic information on ‘green infrastructure’ in New York City.
Why is STEW-MAP important?
STEW-MAP identifies existing stewardship gaps and overlaps in order to strengthen organizational capacities, enhance citizen monitoring, promote broader public involvement in on-the-ground environmental work, and build effective partnerships between people and groups involved in urban sustainability. As funding support for green infrastructure fluctuates, it is important to cultivate long-term, community-based natural resource stewardship. STEW-MAP creates a framework to connect stewardship groups and to measure, monitor, and maximize the contribution of our civic resources.
STEW-MAP’s database and interactive maps allow the public, goverrnment agencies, and nonprofits to visualize where and how hundreds of large and small environmental stewardship groups are working in New York City . This information can guide natural resource management, policymaking, and public outreach. Custom downloads of STEW‐MAP data have been used by the Mayor’s Office of Long Term Planning and Sustainability, the NYC Department of Environmental Protection, MillionTreesNYC, and the NYC Department of Parks and Recreation in support of policymaking and natural resource management activities.
The New York City STEW-MAP data is also being analyzed together with 20 years of land cover data through cutting edge interdisciplinary research as part of a the National Science Foundation-funded ULTRA-EX project, titled “Understanding the Dynamic Connections among Stewardship, Land Cover, and Ecosystem Services in New York City's Urban Forest”.
STEW-MAP was replicated for waterfront-focused stewardship groups in the New York Harbor area, in collaboration with the Hudson River Foundation/Harbor Estuary Project (HRF/HEP). STEW-MAP results are contributing to a needs assessment, which enables HRF/HEP to prioritizing grant funding towards increasing public waterfront access and stewardship.
