Abstract：
The vast majority of the food we eat comes from land-based agriculture, but recent technological advances in agriculture and food technology offer the prospect of producing food using substantially less or even virtually no land. For example, indoor vertical farming can achieve very high yields of certain crops with a very small area footprint, and some foods can be synthesized from inorganic precursors in industrial facilities. Animal-based foods require substantial land per unit of protein or per calorie and switching to alternatives could reduce demand for some types of agricultural land. Plant-based meat substitutes and those produced through fermentation are widely available and becoming more sophisticated while in the future cellular agricultural may become technically and economical viable at scale. We review the state of play of these potentially disruptive technologies and explore how they may interact with other factors, both endogenous and exogenous to the food system, to affect future demand for land.
摘要：
我们吃的绝大部分食物来自于陆基农业,但是农业和食品技术的最新技术进步提供了使用少得多甚至几乎不使用土地生产食品的前景。例如,室内垂直耕作可以以非常小的面积足迹实现某些作物的非常高的产量，一些食品可以由工业设施中的无机前体合成。动物性食品每单位蛋白质或每卡路里需要大量土地，而转向替代品可能会减少对某些类型农业用地的需求。基于植物的肉类替代品和通过发酵生产的替代品是广泛可用的，并且变得更加复杂，而将来细胞农业可能在规模上在技术上和经济上变得可行。我们回顾了这些潜在颠覆性技术的现状，并探讨了它们如何与其他因素相互作用，食物系统的内源性和外源性，影响未来的土地需求。
