Does small mean unimportant? A review of pocket park values and associated factors

Purpose This study aims to explore the value of pocket parks and associated factors, as well as the differences between pocket parks and other green spaces, and finally to identify the role of pocket parks in cities. Design/methodology/approach This study adopts a systematic literature review method to identify 85 articles from the Web of Science and other sources. The Nvivo12plus software was employed to qualitatively analyse the value of pocket parks, and the key associated factors were visualised via the NVivo word cloud function. Findings As a result, pocket parks reflected high social, environmental ecological, cultural aesthetic values but low economic value. Compared to other large-scale green spaces, the particularity of pocket parks lies in their ambiguity and temporality of space and high reliance on the surrounding environment. Small and scattered pocket parks in the city are like “convenience stores” and “green magnets”, and connectivity should be strengthened to promote urban regeneration. Originality/value Compared with previous studies that mostly focused on large urban green spaces, the originality of this study is that it elaborates on the importance and values of pocket parks and proposes the particularity and roles of pocket parks in cities, which enriches the theoretical knowledge of pocket parks. In terms of practical applications, the proposed diverse values and associated factors contribute to guiding the planning, management and operation of pocket parks. Moreover, the roles of pocket parks help enhance park connectivity and establish a park network system.
