evolve into a network of high-performance, resilient, entrepreneurial communities. D'Acci and the T*-minute city Since 2013 D'Acci presented the Isobenefit Urbanism: a spontaneous-guided planning approach based on a morphogenetic code inducing a T*-minute city (T*= a reasonable time to reach destination by walking) where one can reach within 1km/1mile: natural land, shops, amenities, services and places of work. It is based on a code for the simulations of Isobenefit urban morphogenesis. It is a code to simulate urban growth scenario by modifying as one wishes the values of the parameters. The latter are related to densities, surface, population size, random factors and built probabilities. This urban growth model results in infinite outputs all satisfying the Isobenefit urbanism objective function. Weng and the 15-minute walkable neighborhood Weng and his colleagues, in a 2019 article using Shanghai as a case study, proposed the 15-minute walkable neighborhood with a focus on health, and specifically non-communicable diseases. The authors suggest that the 15-minute walkable neighborhood is a way to improve the health of residents, and they document existing disparities in walkability within Shanghai. They found that rural areas, on average, are significantly less walkable, and areas with low walkability tend to have a higher proportion of children. Compared to Moreno et al., the authors focused more on the health benefits of walking and differences in walkability and usage across age groups. Da Silva and the 20-minute city Da Silva et al., in their 2019 article cite Tempe, Arizona, as a case study of an urban space where all needs could be met within 20 minutes by walking, biking, or transit. The authors found that Tempe is highly accessible, especially by bike, but that accessibility varies with geographic area. Compared to Moreno et al., the authors focused more on accessibility within the built environment. Implementations Africa Lagos, Nigeria, converted schools that were closed due to the COVID-19 pandemic into food markets to prevent panic buying. The program also decreased commute times and shored up food supplies within communities. Asia In 2019, Singapore's Land Transport Authority proposed a master plan that included the goals of "20-minute towns" and a "45-minute city" by 2040. Israel has embraced the concept of a 15-minute city in new residential developments. According to Orli Ronen, the head of the Urban Innovation and Sustainability Lab at the Porter School for Environmental Studies at Tel Aviv University, Tel Aviv, Haifa, Beersheba, and central
