The global trend of decreasing arable land has attracted widespread attention. In recent years, with the continuous acceleration of urbanization and the continuous expansion of industrial land and infrastructure, the amount of arable land is decreasing dramatically. In addition, due to the adjustment of agricultural policies and changes in market demand, the quality of cultivated land is also declining. Soil pollution, salinization and the overuse of pesticides and fertilizers have severely affected the productivity of cultivated land.
The importance of arable land conservation cannot be overstated, especially in the context of enormous challenges to global food security. According to the Food and Agriculture Organization of the United Nations, the number of hungry people in the world remains high, and food shortages are even worsening in some regions. Arable land is the foundation of agricultural production, and only by protecting this resource can we ensure the food supply of the future. The health of cultivated land directly determines the yield and quality of crops, which in turn affects food safety and nutrient supply. Especially in the face of climate change and frequent natural disasters, healthy arable land can provide greater resilience to risks and ensure the stability of agricultural production.
In order to effectively protect cultivated land, it is necessary to start from multiple aspects of policy, technology and management. The government should strengthen the construction of laws and regulations, formulate a special law on the protection of cultivated land, strictly enforce the law, and put an end to illegal occupation. For example, although the newly revised Regulations for the Implementation of the Land Management Law in mainland China have some provisions, they still need to be more strictly enforced. At the same time, farmers should be encouraged to adopt scientific farming methods, reduce dependence on chemical fertilizers and pesticides, promote organic agriculture and the combination of planting and breeding, and improve soil fertility.
Modern scientific and technological means should also be fully utilized to monitor and maintain the quality of cultivated land. Remote sensing and geographic information systems (GIS) can help pinpoint areas of soil degradation and enable timely remediation measures. At the same time, through big data analysis and intelligent agriculture platform, the planting structure and production methods can be optimized, and the efficiency of cultivated land use can be improved.
As direct users and beneficiaries of cultivated land, a change in the mindset of farmers is crucial. At present, many of the younger generation of migrant workers no longer depend on the land for their livelihood like their parents. Their emotional ties to the land have gradually become estranged, and they have become indifferent to the maintenance of the soil. Therefore, it is necessary to raise farmers' awareness of land protection through education and training, so that they can re-realize the value and importance of land.
The whole society should actively participate in the action of cultivated land protection. Enterprises and the public can reduce the pressure on the over-exploitation of agricultural resources through green consumption and waste reduction. At the same time, NGOs can promote more social forces to pay attention to and support farmland protection through publicity and advocacy activities.
Cultivated land protection is not only a need for agricultural production, but also a cornerstone of global food security. Only by working together to promote policy, technology and social changes can we effectively protect arable land and ensure a stable and sufficient food supply in the future. In today's increasingly severe global environmental problems, the protection of cultivated land is undoubtedly the unshirkable responsibility of each and every one of us.
