Land & Food Security

Land use multifunctionality (LUMF) is a pragmatic means of resolving land use conflicts and realising regional sustainability and has critical importance in land system science. In this study, we constructed LUMF classifications from a sustainable perspective and quantified and analysed the deliveries of land use functions (LUFs) in the coastal area of Jiangsu Province, China.

As land is limited, conflicts between land uses, and, consequently, conflicts between land users about land use inevitably arise. However, how these land use conflicts affect local land use actors has remained underexplored.

With the development of the green food industry, land conflicts are gradually escalating, and the coordinated development of competitiveness level and land use efficiency is crucial to the green food industry.

Accurate identification of land use conflicts is an important prerequisite for the rational allocation of land resources and optimizing the production–living–ecological space pattern. Previous studies used suitability assessment and landscape pattern indices to identify land use conflicts.

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.

According to the World Bank, approximately 55% of the population lives in cities and a growing trend is expected in the future. Cities generate more than 80% of the world’s GDP, so accurate urban land management would favor sustainable growth, increasing productivity and facilitating innovation and the emergence of new ideas.

Community-based tourism (CBT) has been adopted as an effective and practical solution to land use policies by governments that simultaneously pursue upgrading of local economy, conservation of local ecosystem and development of local communities.

Protecting cultivated land is an urgent mitigation measure for China to reconcile the contradiction between food safety and carbon neutrality.

As an important resource for human survival and development, the utilization efficiency of cultivated land is directly related to national food security and social harmony and stability.

The rural land right has paved the way for the deepening of China’s agricultural land system, which is critical to the successful implementation of the rural revitalization plan in the new era.

The excessive use of cultivated land for non-grain production activities is considered a threat to grain security. This study presents an analysis framework on unraveling the causal mechanisms for non-grain production of cultivated land. We apply the analysis framework in Liyang, which is located in the Yangtze River Delta and is also an important “national grain base” county of China.

Analyzing the relationship between rural settlements and rural population change under different policy scenarios is key in the sustainable development of China’s urban and rural areas.
