Multi-scenario forcasting of residential building stock and demolition waste generation in Fuzhou-Xiamen-Quanzhou

Construction and demolition of buildings in cities pose considerable risks in the urban environment．Fuzhou, Xiamen, and Quanzhou were selected to analyze and predict changes in building stocks and waste generation under three alternative scenarios until the end of this century．Living standards of residents in Fuzhou-Xiamen-Quanzhou are likely to reach or exceed the current levels in Europe and US in the future．Historically, pursuing a high standard of living would bring serious problems in resources and environment．Sustainable developments would maintain a quality life for urban residents and benefit environment．Extending the service-life of buildings could significantly reduce generation of construction and demolition waste in Xiamen．Developing a compact city is effective for both Fuzhou and Quanzhou.
