Sustainable Cities and Communities

Living in a place and sharing choices

Imagine a neighbourhood where a new road makes travel faster but cuts a path to school. A sustainable city is more than “green” buildings. SDG 11 seeks inclusive, safe, resilient and sustainable human settlements. It connects housing, mobility, public space, heritage, air quality, waste, risk and participation.

A system of places

A territory works through relationships: distant housing increases travel time; weak transport limits access to care; a public space without shade or seats excludes some uses. Density can bring services closer but must protect light, quiet and nature. Resilience combines prevention, maintenance, preparedness and mutual support. Decisions benefit from maps and stories, without treating an average as the experience of every street.

Participation and trade-offs

Changing a place creates winners, costs and delayed effects. A cycle lane may improve safety while requiring solutions for deliveries and accessibility. Renovation may reduce energy use but temporarily raise rent. Participation is not asking for opinions after a decision: it includes affected people in defining the problem, designing, testing and evaluating.

Hypothetical example: Four Seasons square

In an imaginary town, a hard-surfaced square is uncomfortable in summer and unwelcoming in winter. A group brings together children, older people, shopkeepers, disabled people and municipal services. It observes use at different times, proposes trees, seating, drinking water and clear routes, then checks maintenance constraints. The trade-off concerns initial cost, available space and long-term benefits. A temporary installation can be tested before construction.

Reflect

• Which use or group is missing from the first description?
• Which trade-off should be visible before a vote?

Act

Draw a sensitive map of an imaginary place: access, comfort, danger, resource and voice to invite. Add a reversible proposal and indicator, such as profiles consulted or duration of use. Work from a window or map if needed; do not photograph anyone without consent.

Connecting local experience and collective action

For an urban space, observe routes, uses, barriers and maintenance. Compare a street, housing or green-space intervention by asking who saves time, who loses access and who funds maintenance. An anonymous map and remote walk-through can complement a meeting. The aim is a more usable place with a planned review.

Connecting these elements helps imagine a city where safety, nature and access to services reinforce one another. Improvements can begin at small scale, with regular feedback and alternatives for people unable to attend. The goal is a usable shared space, assessed over time.

A resilient city considers risks, resources and daily uses. A small improvement should remain maintainable and open to review. Ask how its benefits and costs are shared.

Planning should include maintenance, emergency access and everyday affordability. Review the space with people who use it at different times, and keep a route for changes when evidence or needs shift. This makes the plan practical for residents, visitors and workers alike. A review date helps the group learn from use and maintain trust over time. today
