The current situation of global food and nutrition security is increasingly worrisome, and it is unfortunate that progress in eliminating hunger, food insecurity, and multiple forms of malnutrition has been hindered or even reversed by recent global events. It is estimated that globally, 702 million to 828 million people (8.9 to 10.5 percent) suffered from hunger in 2021, with 150 million added during the COVID-19 pandemic. Approximately 2.3 billion people are in a state of moderate or severe food insecurity, with 11.7 percent facing severe food insecurity. Nearly 3.1 billion people could not afford a healthy diet, which is an increase of 112 million from the last year. The causes of food insecurity are multifaceted, including the impact of the COVID-19 pandemic, the crisis in Ukraine,and climate change. Simultaneously, income levels have been adversely affected, and prices have risen, reducing people’s ability to purchase food and making it unaffordable. Therefore, it is imperative for governments and other stakeholders to act collectively to improve the state of global food and nutritional health. Many countries, including China, have begun to pay more attention to the issue of agrifood systems and are proposing a transition to the multidimensional goals of nutrition and health, green and low-carbon, efficiency, resilience, and inclusiveness. At the international level, a series of high-level international conferences and action plans, such as the UN Food Systems Summit, the Nutrition for Growth Summit, and UN Climate Change Conference (COP26) in 2021 and COP27 in 2022, have demonstrated the importance and urgency of promoting the transformation of agrifood systems. These conferences advocated for countries to work together to transform the way food is produced and consumed to build healthier, sustainable, and equitable food systems. At the domestic level, China has always regarded food security as a top priority for national development. In 2022, the total annual national grain output reached 686.53 million tons and has remained stable for eight consecutive years at more than 650 million tons. In 2022, the Chinese government emphasized the need to “establish a big food concept” and “strengthen the foundation of food security in all aspects” from the perspective of putting people first and better meeting their increasingly diversified food consumption needs. In light of the various risks and challenges posed by the contemporary era, safeguarding food security necessitates a shift from a narrow focus on food production to a more comprehensive consideration of the entire food supply chain. This entails promoting the development of a diversified food supply system and expanding the focus from mere quantity to encompassing multiple objectives related to the “quantity, structure, and quality” of food. Such an approach will serve to bolster the foundations of food security on all fronts.

Agrifood systems are both a contributor to greenhouse gas (GHG) emissions and an important sector for achieving China’s 2060 carbon neutrality goal and mitigating climate change. Rising global temperatures and frequent extreme weather have greatly weakened agricultural production capacity (IPCC, 2021). The need to mitigate climate change by reducing GHG emissions has global consensus. In 2020, the Chinese government made an important commitment toward peaking its carbon dioxide emissions by 2030 and achieving carbon neutrality by 2060. Under China’s 2060 carbon neutrality goal, the contribution of agrifood systems to GHG emissions reduction cannot be ignored. According to estimates by the Academy of Global Food Economics and Policy (AGFEP) at China Agricultural University (AGFEP, 2021), GHG emissions from agrifood systems reached 1.09 billion metric tons (t) of CO2eq in 2018, accounting for 8.2 percent of total national GHG emissions. While ensuring food security as the top national priority, the combined measures can reduce GHG emissions by 47 percent by 2060, compared to 2020 levels; these measures include improving agricultural technologies, reducing food loss and waste, and shifting dietary patterns. When coupled with the carbon sequestration of land use, land-use change and forestry (LULUCF), agrifood systems can contribute significantly to achieving carbon neutrality (AGFEP, 2021).
