The impact of urbanization on urban agriculture: Evidence from China

Consistent, accurate, high resolution, long time-series mapping of built-up land in the North China Plain

“…In parallel, to safeguard food security, the Chinese government has also enacted strict farmland protection regulations (e.g., the Basic Farmland Protection Regulations) that prohibit farmland from being converted to built-up lands . Therefore, an accurate understanding of built-up land dynamics is critical to formulating effective development plans that balance rapid urbanization with increased demand for food production (Zhong et al, 2020). Accurate historical built-up data can be used to project future economic development, as well as derive opportunity costs for future urban expansion (e.g., in terms of reduced food security).…”

Spatial distribution and driving factors determining local food and feed self‐sufficiency in the eastern regions of China

“…For cereals, Figure 5b shows that approximately the same level of arable land per capita is necessary to sustain self-sufficiency across all population density levels, while Figure 5c shows that yield is slightly higher in self-sufficient regions with high population density. A reason for higher cereal yields in highly populated regions could be that big cities in China have high investments, such as high technology-based agricultural facilities and factory production (Zhong, Hu, et al, 2020). For example, the peri-urban agriculture in Beijing and other big cities, which is mainly operated by large-scale enterprises, can efficiently use local resources, stimulate innovation in agricultural production, and facilitate a rapid response to information on changes in agricultural operations (Yang et al, 2010).…”

Risk Assessment of China’s Water-Saving Contract Projects

“…In water-saving contract projects, except for the core technologies of water-saving, infrastructure construction takes up the majority of the projects. With the continuous accumulation of experience in China's infrastructure construction, the impact of force majeure on it has become smaller and smaller [42]. Therefore, Force majeure risk has a trend of accelerated decline.…”
