City Know-hows
Across many cities, residents of informal settlements lack safe, nearby green space. Using Nakuru, Kenya, as a testbed, we show how opening schoolyards to communities outside school hours can rapidly expand walkable access at minimal cost. With basic security and governance measures, this dual-use model can advance health equity and resilience.

Target audience
We recommend our findings primarily to professionals within UN-Habitat and UNICEF who work on public space, urban health, and child-friendly cities; secondarily to the County Government of Nakuru (urban planning and education departments), the headteachers and boards of public schools in Kaptembwa and Rhonda, and NGOs/CBOs focused on safe public space and community health in informal settlements.
The problem
The residents of Kaptembwa and Rhonda have almost no usable public green space. The only sizable open area—the Mazembe Grounds—is dusty, poorly maintained, and not health-promoting. Per-capita open space is about 0.073 m², and formal parks are distant or fee-based, limiting access for low-income households. Yet nearly 90% of residents said they would use more local open spaces if available, underscoring unmet demand and inequity in green provision.
What we did and why
We mapped existing green areas and all schoolyards in the two settlements using GIS, measured yard areas, and modelled 400-meter walking catchments. We complemented this with field observation and three surveys among residents, teachers, and experts. We focused on whether controlled, after-hours access to schoolyards could cost-effectively increase local recreation space and how stakeholders perceive benefits, risks, and the preconditions—especially governance and safety—needed for implementation.
Our study’s contribution
We provide quantified, place-specific evidence that a dual-use model is viable in informal settlements:
• Opening 10 schoolyards would raise accessible open space to ca. 86,000 m² (15 times the current level), or ca. 1.12 m² per person.
• Even with only public schools, gains remain substantial (ca. 0.90 m² per person).
• Two-thirds of residents endorse after-hours access; teachers and experts support pilots, emphasizing security, maintenance, and clear responsibility frameworks.
Impacts for city policy and practice
We recommend a pilot program in selected public schools, co-designed with communities and aligned with county policy. There are three steps to take:
1. Establish MOUs defining liability, opening hours, supervision, and upkeep; pair “soft” measures (community watch, stewardship) with “hard” measures (lighting, surveillance).
2. Seek small-grant upgrades; integrate schoolyards into green-space standards and local plans.
3. Monitor use, incidents, and health/social outcomes to inform scale-up.

For city planners and policymakers, increasing the tree canopy coverage stands out as the most promising green infrastructure planning/management strategies to contribute to health of campus communities/users. The tree canopy data are also more widely available than most other green infrastructure variables, making its use for the purpose of monitoring, intervention, and assessment feasible for various stakeholders.
At the intersection of urban and public health policy, the success of higher-density affordable housing solutions to serve an inclusive well-being agenda depends upon reducing the association of these lifestyles and built environments with loneliness and social isolation. We construct a pro-neighbouring index and test its predictors using an ordinal logistic regression model based on resident survey data.
