New online map to find 15-minute cities

A new web-based tool analyzes major cities like Tokyo, Paris, Atlanta or Barcelona to see how close they are to the 15-minute city concept, where residents take less than those minutes to access essential services by foot, bike, or public transport. According to the study, published in Nature Cities, few cities fit this concept. The tool, which is freely accessible and uses data from 10,000 cities sourced from the open-source packages GeoPandas and OpenStreetMap, could be useful for developing action plans and estimating how viable it is to transform certain cities to follow this model.

Cities receive more rain than nearby rural areas

More than 60 % of the world's cities receive more precipitation than the rural areas around them, according to a study published in PNAS. The paper cites southern European cities such as Milan and Barcelona as examples of these ‘notable anomalies’, but adds that this phenomenon is not common in central and northern Europe. The research team analysed satellite and radar data from more than 1,000 cities around the world between 2001 and 2020.

Reaction: Adolescents and children from low socioeconomic neighborhoods walk less and engage in less physical activity

A study published in the journal PLOS ONE, which includes data from over 3,000 Spanish adolescents and children, has shown that those living in more walkable areas report spending more minutes per day engaging in active transportation compared to those from less walkable neighborhoods. Along those lines, the lowest average minutes spent playing outdoors are observed among participants from neighborhoods with lower socioeconomic status and less walkability. The research is part of the PASOS study, coordinated by the Gasol Foundation.

Neighbourhoods with no space to play, walk or play sport: how the postcode affects children and young people's health

Research involving more than 3,000 adolescents and children from all Spanish autonomous communities concludes that those living in less walkable neighbourhoods with lower socioeconomic status walk less and engage in less physical activity at weekends than those living in more walkable areas with higher socioeconomic status. The paper, published in the journal PLOS ONE and part of the PASOS study, was presented by two of its authors at a briefing organised by SMC Spain.

Reactions: how to make cities that care for young people's mental health

Access to safe public spaces to meet, employment, education and public health are some of the main measures recommended to make cities more friendly to the mental health of young people and adolescents. The analysis, based on surveys of 518 people in several countries, is published in the journal Nature and is intended to serve as a guide for urban planning policies that reduce inequalities and take into account the needs of young people.

Reactions: exposure to urban green spaces is associated with slower epigenetic ageing

Living near green spaces over a long period of time is associated with better health, an association more marked in women and white people than in men and black people, according to a study conducted in four US cities. The analysis concludes that exposure to urban green space between 1985 and 2006 is associated with slower epigenetic ageing, and that this association is stronger in disadvantaged neighbourhoods. The international team publishing this paper in Science Advances includes a researcher from ISGlobal in Barcelona.

Extreme heat and urban health: how to adapt our cities to climate change

Heat waves and other events accentuated by climate change affect health, especially for the most socially vulnerable people. To counteract these effects, mitigation and adaptation plans for cities are designed based on scientific evidence, the implementation of which belongs to the local political sphere. Two experts in urban health and climate governance analysed these problems and their possible solutions in a briefing organised by SMC Spain.
