As an important part of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, the Broad Food Concept innovates traditional food security, emphasizing sustainable development, technological support, and allround food resource development to meet people’s growing needs for a better life. It is a key component of national security education in the new era. Junior high school geography teaching, centered on world and Chinese geography, is rich in relevant educational materials. Thus, this paper proposes integrating the concept into classroom teaching, deepening it through outdoor geography activities and interdisciplinary theme-based learning, to help students establish and practice the Broad Food Concept.
