Urban greening refers to the practice of increasing green spaces in urban areas, such as parks, gardens, and green roofs. This initiative aims to enhance the quality of life for city residents by providing recreational spaces, improving air quality, and supporting biodiversity. By incorporating plants and trees into city planning, urban greening can help mitigate the effects of climate change, reduce heat islands, and manage stormwater. Cities like Singapore and New York have implemented successful urban greening projects, showcasing the benefits of integrating nature into urban environments.
