Sustainable development strategy for historic neighborhood shrinkage: taking Puhuiquan neighborhood in Yulin, China, as an example

Western cities have been confronted with the challenges of 'urban shrinkage' as changes in economic and production models have caused population migrations. China, in its recent history, has experienced rapid and dynamic growth in its cities. However, as its economy is evolving, it too is being confronted with 'urban shrinkage' challenges. Populations have been shifting inside small and medium sized cities in response to problems created during this rapid growth period. Most heritage areas have suffered from depopulation, neglect and disinvestment. The historic Puhuiquan neighborhood in Yulin City is a classic example of the current Chinese version of 'urban shrinkage'. Yulin City, founded as a military city five centuries ago, has shifted its focus away from its historic purpose into a resource-based city. Yulin’s planning developed new areas, drawing population out of the historic Puhuiquan neighborhood. This area is the home to a unique urban cultural landscape where land and architecture have merged to create the development of various types of 'cave' houses. Suffering from the effects of 'urban shrinkage', this research explores the causes and potential solutions for the area employing both 'smart shrinkage' and 'urban renewal' strategies, informed by local resident participation, to develop a sustainable renewal strategy for this heritage area.
