Land system changes are central to the food security challenge. Land system science can contribute to sustainable solutions by an integrated analysis of land availability and the assessment of the tradeoffs associated with agricultural expansion and land use intensification. A land system perspective requires local studies of production systems to be contextualised in a regional and global context, while global assessments should be confronted with local realities. Understanding of land governance structures will help to support the development of land use policies and tenure systems that assist in designing more sustainable ways of intensification. Novel land systems should be designed that are adapted to the local context and framed within the global socio-ecological system. Such land systems should explicitly account for the role of land governance as a primary driver of land system change and food production.

土地系统变化与粮食安全：迈向多尺度土地系统解决方案。

土地系统变化是粮食安全挑战的核心。土地系统科学可以通过对土地可用性的综合分析以及与农业扩张和土地利用集约化相关的权衡评估，为可持续解决方案做出贡献。从土地系统的角度来看，生产系统的地方研究必须在区域和全球背景下进行，而全球评估应面对当地现实。了解土地治理结构将有助于支持土地使用政策和权属制度的制定，从而有助于设计更可持续的集约化方式。应设计适应当地环境并在全球社会生态系统内构建的新型土地系统。
