china’s rapid urbanization
OverviewThis research aims to improve our understanding of China’s extraordinary social, economic and environmental transformation and its impact on urbanization across the country. Given the size and scale of China’s urban development – urban populations have more than doubled during the last 30 years, and more than 70% of economic activity is now located in cities – urban environments are playing an increasingly important role in daily quality-of-life issues, ecological processes, climate, flows of materials, and land transformations. In order to confront the environmental consequences of urbanization at local to global scales, we need to monitor urban expansion and provide projections of its influence into the future.
Our research program has three main components:
1. Detect, measure, and characterize the rates and patterns of land use change in China’s rapidly developing urban system, focusing specifically on 15 urban corridors;
