- Uses participatory GIS methods to measure physical activities and benefits of urban parks.
- Examines relationship between park activities and benefits with park type, size, and location.
- Park type and size are significantly related to the type and amount of physical activities and community benefits received from urban parks.
- Participatory GIS research methods have limitations but appear useful for examining spatial relationships to inform urban parks planning.
“Previous urban park research has used self-reported surveys and physical activity logs to examine associations between physical activity and park features, size, and distance to participants’ homes. In this study, we used participatory geographic information systems (GIS) methods to explore potential correlates of physical activity and other health benefits in urban parks. Using an internet-based public participation geographic information system (PPGIS) system, study participants identified the spatial locations where they engaged in various types of physical activity and where they received other park benefits—environmental, social, and psychological health benefits. Using an urban park typology, we found that different urban park types provide different opportunities for physical activity with linear parks providing the greatest overall physical benefit while other park types provided important non-physical community benefits. Distance to park was not a significant predictor of physical activity but park size was correlated with physical activity and other park benefits. We discuss the strengths and limitations of using PPGIS methods for understanding the benefits of urban park systems.”

- The Collaborative Habitat Investment Atlas is an interactive spatial tool.
- Allows display and rapid adjustment to stakeholder and habitat values.
- Enables on-the-fly changes to “optimal” landscape designs values.
- Models “levels of protection” of multiple habitat laws at many scales.
- Outputs include maps of habitat prioritization for multi-scalar planning.
“Conservation tools have historically been oriented toward optimization for singular decision-makers. A new generation of participatory tools is now appearing and have begun to recognize multiple human values and decision-makers. However, very few tools accommodate a fully interactive process that can account for both ecological and social dynamism and complexity. The Collaborative Habitat Investment Atlas (CHIA) is a participatory tool for conservation prioritization with a strong visual and dynamic capability. The CHIA promotes interaction among stakeholders through two aspects: stakeholders’ ability to alter variable weights to reflect different biodiversity protection requirements; and formula-based dynamic attributes that immediately update results visually.
The overall CHIA modeling process showing engagements and stakeholder values incorporated by slider-bar functionality, data attributes, dynamic updating of attributes (as values adjusted by slider-bars), biodiversity model, level of protection model and threat model and an example of conservation prioritization output map.
“This paper documents the development of the CHIA within its role as a part of an overall adaptive community-based natural resource management pilot project in Australia’s globally significant humid tropical forests. There are two primary innovations of this approach. The first innovation is the dynamic updating of values and other data, allowing rapid feedback on “what-if?” type questions and enhances the public engagement processes. The second innovation is the recognition and spatial description of different levels of protection across the landscape. Results include parcel-based maps that display the three models: biodiversity importance, level of protection and threat. Additionally, the three models were combined and two examples of suitability maps to aid conservation decision-making are included. When integrated into a conservation planning process the CHIA opens lines of communication, allows exploration of alternatives and enables prioritization of investment that captures the diversity of stakeholder preferences in multiple social decision making contexts.”
