Core Viewpoint - The article emphasizes the importance of food security in China, highlighting the "big food concept" proposed by Xi Jinping, which integrates various agricultural resources to ensure a stable food supply for the large population of over 1.4 billion people [1][3][10]. Background - Fujian province is characterized by limited arable land, with per capita farmland only one-fourth of the national average. In the 1980s, the region faced food shortages and a lack of diverse agricultural products, relying heavily on imports from other provinces [2]. Development of the Big Food Concept - Xi Jinping introduced the "big food concept" in 1988, advocating for comprehensive agricultural development. This concept has evolved under the leadership of the central government, emphasizing the need to utilize various resources, including land, sea, and forests, to enhance food production [3][4][10]. Achievements in Fujian - Over 30 years, Fujian has successfully implemented the big food concept, leading to significant increases in food production and diversity. For instance, meat production reached 3.14 million tons in 2024, a 2.5-fold increase since the early 1990s, with poultry meat production increasing 13 times [4][5]. - The province has also become a leading producer of aquatic products, with a per capita consumption of over 220 kg, the highest in the country. The cultivation of edible fungi has expanded significantly, with over 50 species cultivated commercially [4][5]. Key Practices and Results - Fujian has developed a diversified food supply system by integrating marine, forest, and facility agriculture. This includes the establishment of "marine granaries" to enhance seafood supply and "forest granaries" to tap into forest resources for food production [5][7][8]. - The province has also focused on facility agriculture, with over 2.4 million acres dedicated to modern agricultural practices, significantly boosting the supply of key agricultural products [8]. Quality and Safety Assurance - The province has implemented stringent measures to ensure food safety, including a comprehensive traceability system for agricultural products. The overall compliance rate for major agricultural product inspections has remained above 99% [9]. Lessons Learned - The experience in Fujian highlights the importance of a systematic approach to agricultural development, leveraging local resources to enhance food security. It underscores the need for technological innovation, market orientation, and sustainable practices to achieve a balance between ecological and economic benefits [10][11][12].
