City Know-hows
Cities urgently need systemic health checks. Without them, they keep fixing symptoms, wasting scarce budgets, while hidden risks grow. This proposed approach helps cities understand their true health and activate their self-healing capacity instead of constantly firefighting.

The problem
Today, cities assess “urban health” mainly as the health of people living in cities. This ignores the city itself as a complex living system. As a result, cities may appear healthy while exporting pollution, resource depletion, and social costs beyond their borders. This blind spot weakens urban resilience and overlooks the city’s immunocompetence—its ability to adapt, self-organise, and recover from shocks—especially under tight public budgets.
What we did and why
We propose a systemic health check for cities. It identifies the city’s overall health condition before choosing actions. The method combines a rapid health check, a deeper systems analysis, and a capacity assessment. Together, these steps reveal whether a city should optimise existing systems or transform them—helping decision-makers invest wisely, avoid costly mistakes, and strengthen resilience under real financial constraints.
Our study’s contribution
The paper moves beyond outdated approaches that fix urban “pain points.” Instead, it builds on the new science of cities that understand cities as complex, adaptive systems. This reveals unused potential, hidden risks, and leverage points for change. Improving health by constant repairs is no longer affordable. Understanding and activating a city’s self-organising and self-healing capacity is a smarter, economically sound alternative.
Impacts for city policy and practice
Cities should team up with science and conduct regular systemic health checks. This enables evidence-based prioritisation, cross-sector coordination, and smarter use of limited budgets. Rather than reacting to crises, cities can build resilience proactively—strengthening governance, partnerships, and learning capacities. Systemic health checks help cities decide when to optimise and when to transform, safeguarding wellbeing for people and the planet.

My findings suggest that some indicators of neighbourhood physical disorder—specifically the presence of noise, graffiti, and vandalism—are associated with a greater risk for some mental health problems in children, while markers of neighbourhood physical order—neighbourhood cleanliness and well-cared-for dwellings—may have a protective effect.
Walking around the neighborhood is good for older adults health, but the way older adults perceive their surroundings can affect this behavior. This topic has been discussed for some time in high-income countries. There, it is observed that older adults who live in neighborhoods with high residential density, diverse land use, good road connectivity, access to public transport, pleasant aesthetics, security against crime and traffic, presence of recreational facilities, infrastructure for pedestrians and cyclists, green spaces and visible parts of the sky are more likely to walk, whether for utilitarian or recreational purposes. On the other hand, in Latin American countries such as Brazil, where there is a significant increase in the older adults population and challenges related to urbanization and social inequalities, the relationship between the characteristics perceived of neighborhoods by the older adults and walking behavior is still unknown.
We explored the factors that can encourage walking and cycling to school from the adolescents’ perspective, considering individual and built environment factors as well. Travel mode selection, companionship, desired mobility autonomy, and perceptions of pedestrian and cyclist safety regarding traffic were relevant and interconnected.
