To examine differences in land use and environmental impacts between colonist and indigenous populations in the northern Ecuadorian Amazon, we combined data from household surveys and remotely sensed imagery that was collected from 778 colonist households in 64 colonization sectors, and 499 households from five indigenous groups in 36 communities. Overall, measures of deforestation and forest fragmentation were significantly greater for colonists than indigenous peoples. On average, colonist households had approximately double the area in agriculture and cash crops and 5.5 times the area in pasture as indigenous households. Nevertheless, substantial variation in land-use patterns existed among the five indigenous groups in measures such as cattle ownership and use of hired agricultural labor. These findings support the potential conservation value of indigenous lands while cautioning against uniform policies that homogenize indigenous ethnic groups.
为了研究厄瓜多尔北部亚马逊地区的殖民者和原住民之间的土地利用和环境影响的差异，我们将来自 64 个殖民区的 778 户殖民者家庭和 36 个社区的 499 户原住民家庭的家庭调查数据与遥感图像数据进行了结合。总体而言，森林砍伐和森林破碎化的指标在殖民者中显著高于原住民。平均而言，殖民者家庭的农业和经济作物用地面积大约是原住民家庭的两倍，而牧场面积则是原住民家庭的 5.5 倍。尽管如此，在牛的所有权和雇佣农业劳动力的使用等方面，五个原住民群体的土地利用模式存在着显著的差异。这些发现支持了原住民土地的潜在保护价值，同时也警告不要采取统一的政策来同化原住民群体。
