Protecting cultivated land is an urgent mitigation measure for China to reconcile the contradiction between food safety and carbon neutrality. In the context of carbon neutrality, this paper constructs an evolutionary game model among local governments, agricultural technology service organizations (ATSOs), and farmers based on China’s cultivated black land, and discusses the factors influencing the strategy choice of each stakeholder group and the final form of evolutionary stabilization strategies adopted by each stakeholder from the perspective of agricultural extension.

With the tightening of resource and environmental constraints and the increasing manifestation of land use conflicts, construction land reduction has become an important way to optimize land resource allocation and improve resource use efficiency. Taking the towns of Zhuqiao and Zhujiajiao in Shanghai as research subjects, this paper uses field research and case studies to summarize the main practices and completion of the land reduction and analyzes the interest preferences of different stakeholders.

Access to land is crucial for food systems to address the challenges caused by habitat and biodiversity loss, land and water degradation, and greenhouse gas emissions. Sustainable food production requires land security upstream for agricultural production. Land security emanates from the land law implemented in-country by government policy. In the span of a decade (2007–2017), three different land reforms have been adopted in Benin.
