The socioeconomic causes of land use change are complex. They are highly context dependent, but most often studied through case studies. Here, we use a quasi-experimental paired block design to investigate whether better access to wage income leads to more visible land use around 28 settlements in six regions of the circumpolar Arctic. We mapped visible land use on high-resolution satellite images taken both close to the settlements, and in a more remote area of extensive land use, and payed special attention to tracks of off-road vehicles (ORV). Despite considerable differences among regions, there was an overall positive relationship between better access to wage income and land use. Reindeer herding was also associated with more visible use, in particular ORV tracks. These results suggest that access to wage income in the mixed subsistence-cash communities of the Arctic could lead to more local use related to harvesting and reindeer herding.
土地利用变化的社会经济原因很复杂。它们高度依赖于背景，但通常通过案例研究进行研究。在这里，我们使用准实验配对块设计来调查获得更高的工资收入是否会导致北极地区六个区域的 28 个定居点周围更明显的土地利用变化。我们在高分辨率卫星图像上绘制了定居点附近和更偏远的广泛土地利用区的可见土地利用情况，并特别关注了越野车（ORV）的轨迹。尽管各地区之间存在很大差异，但更好地获得工资收入与土地利用之间存在总体正相关关系。驯鹿放牧也与更明显的利用有关，特别是越野车的轨迹。这些结果表明，在北极混合生计-现金社区中获得工资收入可能会导致与收获和驯鹿放牧相关的更多本地利用。
