City Know-hows
Our study found that 39.2% of the individuals were food insecure. In these surroundings, there is a high number of ultra-processed food trades, but significantly closer to places with lower prices of fruits, vegetables and greens and greater availability of light 03 pay 02 advertisements for natural foods.

The problem
The northeast of Brazil has a high prevalence of moderate and severe food insecurity, a condition in which people need to reduce the amount of food consumed, and in some cases stop eating for more than one day. As an aggravating factor, the food environment close to their homes has a high availability of establishments that sell ultra-processed foods plus a shortage of natural foods.
What we did and why
We decided to evaluate the prevalence of moderate and severe food insecurity among adults in northeastern Brazil and verify the relationship with the food environment, at 1600m (the most used metric) and at 800m, considering this a more accessible distance for individuals to buy food on foot or with greater ease of access. We would like to assess the availability of ultra-processed foods and natural food options closer to homes.
Our study’s contribution
This situation reflects the severity of the food situation in the locus of development of this study, especially when compared to the worldwide prevalence of 29.6% (UN 2024). Establishments that primarily sell ultra-processed foods were twice as concentrated at 800m from the households when compared to 1600m, demonstrating the excess of supply of these products closer to individuals in food insecurity. The low availability of natural/minimally processed food establishments in the two metrics evaluated, portrays the low supply of foods directly associated with health, well-being and quality of life.
Impacts for city policy and practice
Understanding the distribution of food establishments will help policymakers, planners, and managers in spatial planning to control for the sale of healthy food at affordable prices. For urban planning, we highlight the need to add natural food establishments and look at confronting the excess trade of ultra- processed foods. We recommend improving the food system, with markets and street markets, encouraging local and organic agriculture, at a distance where individuals can shop close to their homes.

Increasing the availability of urban green spaces, even small pocket green spaces, should be considered a promising intervention for reducing depression among older individuals. Beyond 100m, urban green space protection diminishes. WHO recommends that the population have a green space within a 300m radius. However, for older people, this threshold may be too distant.
However, not all green spaces confer mental health benefits; therefore, researchers and professionals should consider the differential effects of different categories of greenery.
This study adds to the literature on the health impacts of lockdowns by examining longitudinal changes in the health behaviours of Australian apartment residents. Following the COVID-19 lockdown, residents reported increased walking for recreation, sleep duration, and home cooking frequency, but decreased walking for transport, greater sitting time, and weight gain. Alcohol consumption remained stable.
Public parks shape how people meet, stay, and interact. This study shows how specific physical features of an urban park influence everyday social life, offering practical lessons for designing public spaces that support social interaction, wellbeing, and inclusive urban vitality. We combined on-site observation of people’s behaviour with surveys of park users and spatial analysis. We did this to move beyond abstract design principles and provide evidence-based insights into how seating, pathways, land use, inclusiveness, and safety shape everyday social interactions in public spaces.
