社会经济冲击、技术性灾难和武装冲突往往对当地和区域的粮食安全造成严重影响，破坏农业生产和粮食贸易，减少投资，土地和基础设施恶化。最近，更多的研究集中在武装冲突对土地系统的影响，但对这些事件的过程和结果仍然知之甚少。在这里，我们以叙利亚和伊拉克以及2014年以来伊斯兰国（IS）夺取土地为例，作为武装冲突的例子，调查对农业土地使用的影响。我们采用一种可重复的方法，使用2.5亿基于卫星的时间序列数据来量化2000年至2015年的种植面积。尽管人们普遍认为，在冲突地区普遍存在土地撂荒现象，但结果表明，在伊斯兰国占领的地区，耕地种植有多种轨迹：（1）耕地扩大到以前未耕种的地区，（2）耕地撂荒，（3）高密度耕地减少。我们的研究强调，需要了解这些不同的冲突相关的和背景依赖的变化，土地制度。
Socio-economic shocks, technogenic catastrophes, and armed conflicts often have drastic impacts on local and regional food security through disruption of agricultural production and food trade, reduced investments, and deterioration of land and infrastructure. Recently, more research has focused on the effects of armed conflict on land systems, but still little is known about the processes and outcomes of such events. Here we use the case of Syria and Iraq and the seizure of land by the Islamic State (IS) since 2014 as an example of armed conflict, where we investigate the effects on agricultural land use. We apply a reproducible approach using 250m satellite-based time-series data to quantify the areas under cultivation from 2000 to 2015. Despite a common belief about widespread land abandonment in areas under conflict, results point to multiple trajectories regarding cropland cultivation in the IS seized area: (1) expansion of cropland to formerly un-cultivated areas, (2) cropland abandonment, and (3) decrease of high-intensity cropland. Our study highlights the need to understand these diverse conflict-related and context-dependent changes to the land system.
