本文根据历史航拍照片重建了大萧条时期堪萨斯州的土地覆盖模式，并将农田的位置与现代数字土壤调查地图中确定的亚边缘土地区域进行了比较。分析认为，新政土地退休计划高估了不良土地利用的程度，因为他们缺乏基本的科学，使全面评估。研究结果表明，滥用不适合耕种的土地在整个中部平原相对罕见，但在沙尘暴地区尤其如此。
This article reconstructs land cover patterns in Depression-era Kansas from historical aerial photos and compares the locations of crop fields to areas of submarginal land identified in modern digital soil survey maps. The analysis argues that New Deal land retirement programs overestimated the degree of bad land use because they lacked the basic science to make comprehensive assessments. The findings demonstrate that the misuse of land unfit for cultivation was relatively rare across the central plains but especially in the Dust Bowl region.
