A European-Chinese Exploration Part 2
Urban Ecosystem Service Patterns, Processes, and Contributions to Environmental Equity under Different Scenario
In WP 3, the impact of urbanization on land cover and its subsequent effect on ecosystem services (ES) is a significant concern for sustainable development. Therefore, we investigated the spatiotemporal changes in land cover and ecosystem services in the three ULLs each from China and Europe with different development histories, and for three contrasting future scenarios. Urbanization from 2000 to 2020 was more intense in the three Chinese cities (+84% in built-up area) compared with the three European cities (+11.6 % in built-up area). To estimate future development of all the cities under investigation, we simulated future land-cover changes under three different scenarios, including business-as-usual (BAU), a market-liberal scenario (MLS), and an ecological protection scenario (EPS). Due to rapid land-cover change, our results showed that Chinese cities have experienced more dramatic changes in ecosystem services than European cities. However, the EPS scenario was highly effective in increasing both the quantity and equity of ES distribution. The multi-scenario analysis can provide urban planners and policy makers with more reference dimensions that not only guide urban planning policies, but also show the spatial distribution characteristics of ecosystem services and their impacts under different scenarios. In addition, increasing attention is also being paid to the equitable distribution of ecosystem services, especially when the aim is to achieve a more equitable environmental policy. If we want to advance the achievement of the SDGs in cities, equitable urban development is an essential prerequisite.
