本技术指南由联合国粮食及农业组织（粮农组织）与《联合国防治荒漠化公约》共同编写，并吸纳了若干利益攸关方的意见和建议，旨在将《国家粮食安全范围内土地、渔业和森林权属负责任治理自愿准则》（《权属自愿准则》）纳入《公约》的执行和土地退化零增长目标，为荒漠化、土地退化和干旱应对工作开启了新的篇章。
本指南简要介绍了《权属自愿准则》（国际认可的负责任权属治理框架）在设计和实施土地退化零增长举措背景下的实际应用。指南提供了多个灵活途径，支持政策和决策制定者及利益攸关方通过着眼于应对土地退化的各类国家规划、法律框架、战略及行动计划，就普遍遇到的土地权属挑战采取因地制宜的响应措施。
Revitalizing idle rural residential bases is essential for improving the utilization rate of residential resources, activating pastoral land resources assets, increasing farmers’ property income, and stimulating rural development vitality.
With the intensification of the contradiction between living space and population growth, it is necessary to improve the effectiveness of urban residential land allocation.
Land expropriation has always been a hot spot of social conflicts. The land expropriation policy of Merging Villages and Living Together (MVLT) in rural areas has intensified conflicts due to insufficient financial compensation and “demolishing old houses before building new ones”.
Climate change, land degradation, and desertification lead to the loss of carbon present in the soil and plants. The carbon dioxide (CO2) concentration in the atmosphere has reached 412 ppm. This is a rise of 47% since the start of the industrial period, when the concentration was close to 280 ppm. Therefore, the sequestration of carbon from the atmosphere to earth is the need of the hour.
Because the relationship between cultivated land and the surrounding land types is not taken into account, there existed a deviation in the assessment of cultivated landscape ecological security.
The withdrawal of rural residential land-use rights is a major initiative in China’s current rural land reform, and it is of great importance in promoting the rural revitalization and urbanization strategy. The Chinese government encourages farmers to withdraw from their residential bases in an orderly manner to effectively revitalize land resources.
Carbon and nitrogen are among the most important biogenic elements in terrestrial ecosystems, and carbon and nitrogen stable isotopes (δ13C and δ15N) are often used to indicate the sources of carbon and nitrogen elements and turnover processes, and the study of C and N isotopes coupling can provide more precise indications.
The Mekong Delta region has been seriously affected by climate change, with increasing temperatures, sea-level rise, and salinization strongly impacting agricultural activities of the region. Recent studies have shown that groundwater exploitation also contributes significantly to land subsidence throughout the delta.
Conversion rule is a key element for a cellular automata (CA) model, and it is a significant and challenging issue for both domestic and international experts. Traditional research regarding CA models often constructs a single conversion rule for the entire study area, without differentiating it on the basis of the unique growth features of each location.
