自从Shipibo人开始种植经济作物水稻以来，他们的土地利用模式发生了变化，对最适合种植芭蕉的软桑迪土壤的利用比例降低，而对更适合种植水稻和块根作物的硬粘性土壤的利用比例增加。土壤样品的统计分析揭示了Shipibo土壤类别的物理化学基础，并表明了刀耕火种农业对重要土壤特性水平的影响。虽然种植的文化原则在过去总结了这些重要的生态关系，但随着水稻产量的增加，它们往往被违反。时间分配和食物消费数据的研究表明，Shipibo土地利用模式的变化与农业周期短时期内较高的劳动力成本和对驯养动物食物的依赖程度有关。
Since the Shipibo began cash cropping, rice, their land use patterns have changed with proportionately less utilization of soft sandy soils, which are best for staple Musa production, and greater use of harder clayey soils, which are more suitable for rice and root crops. Statistical analysis of soil samples reveals the physical-chemical basis of Shipibo soil categories and indicates the effect of swidden agriculture on levels of important soil characteristics. While cultural principles for planting have summarized these important ecological relationships in the past, they are often violated with increasing rice production. Examination of time allocation and food consumption data shows that changes in Shipibo land use patterns are associated with higher labor costs during brief periods of the agricultural cycle and greater dependence on domesticated animal foods.
