“…National nutrition and food security are related to dietary structure and human health and are affected by agricultural production activities, resource and environmental pressures, and food supply and demand patterns (Burchi & De Muro, 2016 ; Deng et al, 2015 ; He et al, 2018 ). In recent decades, the sustainable development of China’s agriculture system has faced enormous challenges, including excessive water resource consumption in the north caused by the policy of “bringing bulk grain from North China to the South” widespread agricultural surface pollution due to excessive pesticide and fertilizer use, and the continuous reduction of arable land due to the promotion of urbanization (Liu & Deng, 2010 ).…”

Food security and the utilization of natural resources in a sustainable manner are vital to the expansion of China's agricultural system. The relationship between environmental pressure and dietary structure has influenced the quantity and spatial distribution of China's food supply and demand, but it has not been evaluated. Our research centered on the security of China's food nutrition–resources–food (NRF) system, considering the inherent relationship between food security, nutritional health, and resource security. The following are the study's findings: (1) The Chinese population is rapidly changing from a diet focused on grains to a more diverse diet. Between 1990 and 2019, the dietary quality and nutritional status of Chinese individuals have vastly improved. In terms of nutrient levels, discrepancies between urban and rural resident persist, with urban residents consuming a diet that is closer to the ideal structure. However, the structure of rural residents' food consumption is diversifying, and the gap between urban and rural residents is gradually narrowing. (2) From 2000 to 2019, the pressure, status, and response indices of China's NRF system all show an upward trend, and the security of the NRF system has steadily grown. The magnitude of change in the response index exceeded that of the state index, which exceeded that of the pressure index. This indicates that the increase in the pressure and state indices of the NRF system was primarily attributable to the effectiveness of policy efforts.

Intense transformation and conflicts between different land use types has occurred in the past decades and will still exist in the coming decades in China. Ascertaining the quantity and pattern optimization of urban ecological land is critical to guaranteeing urban ecological security and realizing urban sustainable development. In this study, Nanjing, a very famous city in the Yangtze River Delta in China, was selected as the case study to explore the land use changes from 1995 to 2017 and calculate the suitable amount of ecological land to meet the needs of its socioeconomic development. From 1995 to 2015, the proportion of ecological land in Nanjing dropped from 84.41% to 59.15%. Based on the minimum cumulative resistance model (MCRM), we designed four alternate scenarios to explore the optimal quantity and pattern of ecological land in Nanjing. By comparing the current land use status with the model simulation results, we proposed the suitable ecological land area for Nanjing should be no less than 3963km2, which is 56% of the total area of Nanjing. The land use strategies and the measures to protect ecological land in this study can provide a reliable reference for sustainable development of other highly urbanized regions in China.
