The Multifaceted Impact of Urban Gardening for Enhancing Environment, Health, And Community

Urban Farm DB summary

Urban gardening, an ancient practice, is described as having gained renewed significance amid rapid urbanization and associated challenges including environmental degradation and declining mental health. This study explored the multifaceted role of urban gardening in environmental, social, and health dimensions of sustainable urban development across five cities: New York, Berlin, Mumbai, São Paulo, and Nairobi. It combined structured surveys of 300 participants (covering air quality, access to fresh food, social interactions, and mental health), semi-structured interviews with 30 stakeholders including city planners and community garden managers, field observations of gardens' ecological and physical characteristics, and a review of secondary data. Results showed 67% of respondents reported improved mental health, with São Paulo and New York showing the most positive outcomes. Urban gardening contributed to reducing the urban heat island effect, with temperature reductions of up to 4°C, enhanced biodiversity by hosting various plant species that created habitats for pollinators, and served as social hubs fostering community engagement and inclusivity; 60% of respondents in São Paulo reported improved access to fresh food. The study concludes that urban gardening significantly enhances environmental sustainability, social cohesion, and mental health, particularly in marginalized communities, but states that challenges such as land access and insufficient policy support hinder its potential.
