Spatial Social Design
Two halves of one system.
GeoDesign moves from place toward people. CBSM moves from people toward place. Each is strong on its own, and each has a blind spot the other fills.
| GeoDesign | CBSM | |
|---|---|---|
| Direction | Spatial to social | Social to spatial |
| Scale | Global to local: regions, watersheds, cities | Local to global: one behavior, one community, then scaled |
| Core question | Where, and what if? | Why, and what's in the way? |
| Strength | Seeing the consequences of change across a whole landscape | Changing what people actually do, with measured results |
| Blind spot | Often assumes how people will respond | Often treats place as background |
GeoDesign helps planners evaluate proposed changes to a place. Behavioral research adds how people are likely to respond, so designs that look good on paper don't fail in practice. And because the map works at every scale, the same approach connects a single neighborhood to much larger goals.
“We can use the spatial side of GIS for environmental goals from a global level all the way to the local scale.”
Steve Jewett, Environmental Alliance
For every geographic action, there is a corresponding and mostly predictable effect.
"Mostly" matters. Place doesn't dictate behavior, but it shapes it in ways we can map, measure, and design for. Spatial Social Design is the practice of working with both at once.What changes when they work together
Combined, the two disciplines form a single loop. GIS strengthens every step of CBSM, and behavioral research grounds every GeoDesign decision. Each pass makes the next one sharper.
Find the priority places and people
Map where a behavior causes the most harm and who lives or works there, so effort goes where change matters most.Treat barriers as layers
Many barriers are physical and can be mapped. Plotting existing trash cans alongside litter concentrations, for example, shows where new receptacles are most likely to help.Design the place and the prompt together
Change the setting and the social cues in the same intervention. Visible examples matter too: solar panels or a converted lawn in a prominent spot may encourage neighbors to follow, and mapping adoption shows whether that influence spreads.Pilot in comparable places
Use the map to choose test and comparison sites with similar conditions, so results are fair and clear.Measure what changed, not who saw it
Success isn't how many people encountered a campaign. For an irrigation program, it's whether residents changed how they water and whether runoff actually declined. Mapping both over time shows whether gains last and how they vary by neighborhood.Scale by similarity
A strategy that works in one community won't automatically work everywhere. In wildfire preparedness, residents of isolated homes face different challenges than those in dense neighborhoods. The map finds places with similar conditions where a proven strategy deserves its next test.
Bring behavior in at the start
GIS specialists and outreach teams often work separately, so geographic insight rarely shapes the campaigns, and behavioral insight rarely shapes the designs.
“Behavior tends to be an afterthought.”
Jennifer Tabanico
The fix is timing. Involve behavioral scientists when the problem is first defined, before a solution is chosen, and build behavioral research into GeoDesign from the outset. Planners can then account for how people will actually use a physical improvement, and what will encourage them to adopt new practices.
The missing layer is infrastructure
Most of the pieces already exist. What's missing is the shared foundation that lets them connect: common data standards, maps that record behavior alongside landscape, and coalitions that carry proven results from one community to the next. Building that layer is the work of Environmental Alliance. How we work.
A book on Spatial Social Design is in development. More to share in 2027.
