Study Reveals Urban Cooling Effects of Informal Settlement Demolition in China
A recent study has investigated the impact of demolishing informal settlements on urban land surface temperatures in major Chinese cities. Using a quasi-natural experiment and difference-in-differences analysis, researchers examined 661 informal settlements in Beijing, Shanghai, and Guangzhou from 2002 to 2022. The study found that demolition led to significant cooling effects, with an average temperature decrease of 1.47 K across all cities. Beijing experienced the most pronounced cooling, attributed to its semi-arid climate and urban planning regulations that promote green spaces. The study highlights the role of redevelopment in transforming dense informal settlements into formal neighborhoods, contributing to lower local temperatures.
