China food security comprehensive assessment dataset 2012-2022

In the context of the new development pattern, China's food security is facing new risks, such as insufficient impetus for the sustainable enhancement of its comprehensive production capacity, and the existing grain statistics are fragmented and not comprehensive enough to meet the needs of current food security assessment studies.In this study, we constructed the time-series China Food Security Comprehensive Assessment Dataset (CFSAD,2012-2022), which includes five categories of grain, rice, wheat, corn and soybean, and covers five dimensions of the basic guarantee level, the market operation situation, the scientific and technological support capacity, the resource and environmental conditions, and the level of purchasing power, and includes fourteen indicators,such as the mean value of the risk of price volatility in the grain market,CO2 equivalent emissions by grain production,growth rate of per-mu cash receipts, etc.The dataset will be updated annually, and our dataset enables a more scientific and comprehensive assessment of China's food security situation, which can provide data support for effective government policy making and academic research.
