We consider trends in the use of modern agricultural inputs of migrant settlers and indigenous populations in the Northern Ecuadorian Amazon and the demographic, socioeconomic, and land use-related factors affecting input use. It is widely believed that the different livelihood strategies and therefore different relationships to the land of indigenous populations and migrant settlers result in different uses of chemical inputs in agriculture. We analyze data from two panel surveys, one of migrant settler households and a separate panel of indigenous households. We find low input use among both types of households, particularly among two of the five main ethnicities of indigenous households in the study region, the Cofán and Waorani. Multivariate statistical models were run separately for each panel, with significant relationships found between several predictors and the use of pesticides and herbicides. Our results highlight continuing differences in land use patterns between households in the NEA.
我们研究了厄瓜多尔北部亚马逊地区移民定居者和原住民使用现代农业投入品的趋势，以及影响投入品使用的人口、社会经济和土地利用相关因素。人们普遍认为，原住民和移民定居者不同的生计策略以及因此与土地的不同关系，导致了农业中化学投入品的不同使用情况。我们分析了来自两项面板调查的数据，一项是移民定居者家庭调查，另一项是独立的原住民家庭面板调查。我们发现这两类家庭的投入品使用量都很低，尤其是在研究区域内五个主要原住民族群中的两个族群——科范族和瓦奥拉尼族中。针对每个面板分别运行了多元统计模型，发现几个预测变量与农药和除草剂的使用之间存在显著关系。我们的结果凸显了东北亚马逊地区家庭之间土地利用模式的持续差异。
