We first analyze the spatial correlation of urbanization and urban agriculture using the spatial Moran index. We, then, perform an empirical analysis using the Spatial Durbin Model. We find that: (1) Both urban agriculture and urbanization have spatial autocorrelation. From 2001 to 2012, the spatial autocorrelation

While wetlands contribute significantly to ecosystem services, their nature as a public good implies that the public sector, rather than the market, values their conservation, utilization, and trade-offs among various ecosystem services. Thus, the valuation of wetlands and their ecosystem services is important for policy makers. This study conducts a meta-analysis of valuation research on China’s wetlands

The problem of externalities is an important aspect of contemporary discussion about the directions of agricultural development and agricultural policy. Nonetheless measuring agri-environmental externalities is a difficult task and rarely undertaken in scientific research. In our research, we have constructed a synthetic indicator that allows measuring agri-environmental externalities at the regional

The transition towards a more resource efficient economy require suitable policies to regulate the resources needed to support development initiatives. Unregulated extraction of natural resources to support infrastructure expansion activities has led to resource constraints and environmental degradation.
