In August 2023, the Qinghai Provincial Commission for Discipline Inspection and Supervision reported 6 typical cases of ineffective performance in the field of farmland protection; In July 2023, the Discipline Inspection Commission and Supervision Commission of Dalian City, Liaoning Province reported three cases of irresponsibility, inaction, and disorderly behavior in farmland protection work; In April 2023, the Hunan Provincial Commission for Discipline Inspection and Supervision reported 7 typical cases of farmland being "non agricultural" and basic farmland being "non grain". Recently, disciplinary inspection and supervision agencies in various regions have exposed the issue by name, releasing a strong signal of using iron discipline to protect farmland and food security. Cultivated land is the lifeblood of food production. The report of the 20th National Congress of the Communist Party of China emphasizes: "Fully implement the shared responsibility of the Party and government for food security, and firmly hold the red line of 1.8 billion acres of arable land. What are the main issues with the current "non agricultural" conversion of arable land and the "non grain" conversion of permanent basic farmland? How to strengthen political supervision around the protection of arable land as the "great figure of the country"? How to thoroughly investigate the responsibility, corruption, and work style issues behind the chaos of farmland protection? The reporter interviewed comrades from the Discipline Inspection and Supervision Group of the Central Commission for Discipline Inspection and the National Supervision Commission stationed in the Ministry of Natural Resources and relevant local discipline inspection and supervision commissions. The national situation of China with a large population and limited land has not changed, and the issue of "non grain" and "non agricultural" cultivation of arable land still highlights that food security is the "major concern of the country", and arable land is the lifeblood of food production. In recent years, a series of strict policies and measures for farmland protection have been introduced, but there are still some illegal and illegal occupation of farmland for non agricultural construction in some places. In September 2020, the State Administration issued a notice on resolutely stopping the "non agricultural" behavior of cultivated land, which stipulates that illegal occupation of cultivated land for greening and afforestation, construction of green channels exceeding standards, illegal occupation of cultivated land for lake digging and landscaping, occupation of permanent basic farmland for expanding natural conservation land, and illegal occupation of cultivated land for non agricultural construction are strictly prohibited. In November 2020, the State Council issued the "Opinions on Preventing the" Non Grain Conversion "of Cultivated Land and Stabilizing Grain Production", which prohibits the occupation of permanent basic farmland for forestry and fruit production, as well as activities such as digging ponds for fish farming, illegal soil extraction, and other activities that damage the cultivation layer. It also prohibits the idle or abandoned permanent basic farmland. The person in charge of the Discipline Inspection and Supervision Group stationed at the Ministry of Natural Resources told reporters that the main problems that have caused the "non agricultural" and "non grain" conversion of farmland over the years have been concentrated in the occupation of farmland, such as the construction of green channels beyond the standard. For example, the green belt on both sides of a provincial highway in a province is 60 meters wide, far exceeding the national standard of 3-5 meters, and the green belt occupies nearly 1800 acres of farmland; The adjustment of agricultural structure has led to imbalanced planting structure, and insufficient policy guidance for planting structure adjustment has led to some regions being driven by economic interests to plant cash crops on farmland. The responsible comrade introduced that the 112 major violations and violations discovered by the Ministry of Natural Resources in 2021 and 2022 during the inspection of cultivated land protection have all reflected the weak awareness of cultivated land protection among relevant local government and competent department leaders, leading to the occurrence of illegal occupation of cultivated land due to inadequate enforcement and supervision responsibilities. From the reports of disciplinary inspection and supervision organs, it can be seen that the cases of "non agricultural conversion" of cultivated land and "non grain conversion" of permanent basic farmland
