Abstract
The rural-urban (peri-urban) interface zones are important places that generate demands for ecosystem goods and services (EG & S). Urban regions face transitions in land use that affect ecosystem services (EG & S) and thus human wellbeing. Especially in urban areas with high population densities (as in most of China) and high demand for EG & S, the future availability of such services must be considered in order to promote effective and sustainable decision making and prevent further ecosystem degradation. The challenge for local government planners and land managers is to find tools that allow relevant data to be collected and analyzed. Ideally, such tools should be able to give a rapid assessment, and not involve large teams of highly trained personnel or incur high costs. The paper reports on the development and trial of such a tool. The paper has three main parts. First, we present a brief overview of the current and developing situation in China, in relation to urbanization, population shifts and the creation of peri-urban areas (PUAs). Next, we build on insights from the literature and from discussions with village heads and county- and prefecture-level officials to develop an understanding of their needs for tools to help planning and land management within the constraints of the national policy. Lastly, a “template” was derived from our multi-method approach that provided a new technical tool for the rapid assessment of the value of EG & S in each of five land use categories. The tool embodies a way to address trade-offs between environmental, social and economic values in the transition zone between rural and urban areas. The tool was trialed in QinBei District in Guangxi Autonomous Region in south China and judged to be useful and adaptable to other rural–urban regions.
Highlights
Context and SettingChina is undergoing rapid urbanization [1,2,3,4,5,6] and according to the data from the national bureau of statistics, the rate increased from 10.64% in 1949 to 58.52% in 2017 and reached 60% in 2019
We focused on the development of a “tool box”, including the derivation of an ecosystem service index (An ecosystem service index (ESI) is a calculated weighting of many relevant attributes to derive a single number between 0 and 1, where 0 is the lowest
Close interdependence between people and supportive ecosystems is further endorsed by our exploration of systemic linkages between the key social, technological, environmental, economic and political dimensions under the social, technological, environmental, economic, political (STEEP) model
Summary
China is undergoing rapid urbanization [1,2,3,4,5,6] and according to the data from the national bureau of statistics, the rate increased from 10.64% in 1949 to 58.52% in 2017 and reached 60% in 2019. David Simon [14] as (i) absorbing urban migrants, as (ii) sources of food, water and other resources and as (iii) key areas for the disposal of urban wastes They are typically, zones of mixed land use and livelihoods. On account of these characteristics, and the interactions between such areas and the cities, they have come to be known as peri-urban zones or interfaces (PUIs) and have become major research foci in their own right. The importance of PUIs everywhere lies in their dynamic mix of functions and land uses; increasing population densities; growing significance as sources of urban food, construction materials and other resources; as urban waste disposal or treatment sites; and as recreational zones. The spread of urban activities and land uses into rural areas create complex mosaics of juxtaposed activities previously regarded as incompatible, e.g., computer assembly workshops adjacent to rice paddy fields or sugar cane plantations, and urban activities and urban-oriented leisure activities, e.g., golf courses abutting rural villages [8]
