The densification tendencies in cities led to a series of problems. Unpredictable weather, biodiversity destruction, dangerously high carbon emissions, air and noise pollution, increasing class differences, and house crisis are all the challenges that the developed city now faces. The small green space (Patches) can help reverse this in some way. For example, soil and trees help to reduce carbon emissions by absorbing carbon from the air. This, in turn, creates cleaner air to breathe in the locality. Urban green areas can soak up rainwater that may otherwise cause flooding, plus wetlands can store excess water safely. In dense city areas, they might contribute to satisfying the need for everyday experiences in outdoor areas.
The study《Use of small public urban green spaces》investigated that Small Public Urban Green Spaces are primarily used for ‘social interaction’ and ‘rest and restitution’. A well-designed outdoor space should include access to sunlight, grass, water, and trees, or at least some of it. Such a space contributes to an attractive atmosphere in the city and creates space for spontaneous social life. Furthermore, large green spaces become a limited resource, many people live in city areas where the distance to larger green areas reduces the possibility for frequent use. The small public urban green spaces are becoming more critical in the future.
