This paper examines changes over time for a full generation of migrant settlers in the Northern Ecuadorian Amazon (NEA). Data were collected from a 2014 household survey covering a subsample of households surveyed previously in 1990 and 1999. We observed changes in demographic behavior, land use, forest cover, and living conditions. As the frontier develops, human fertility is continuing to decline with contraceptive prevalence rising. Meanwhile, out-migration from colonist households, largely to destinations within the region, persists. More households have secure land tenure than in 1999, and are better off as measured by possession of assets. There is continued growth in pasture, largely at the expense of forest. Farms still serve as an important livelihood source for families, though growing cities in the NEA are creating more non-agricultural economic opportunities. Our findings provide a snapshot of demographic, economic, land use, and livelihoods changes occurring in the NEA during the past quarter century, providing useful information for policymakers seeking to balance economic and environmental goals in order to promote sustainable development as well as protect biodiversity.
本文研究了厄瓜多尔北部亚马逊地区(NEA)整整一代移民定居者随时间的变化情况。数据收集自2014年的一项家庭调查,该调查涵盖了1990年和1999年之前调查过的部分家庭样本。我们观察到了人口行为、土地利用、森林覆盖和生活条件的变化。随着边境地区的发展,人类生育率持续下降,避孕普及率上升。与此同时,殖民者家庭的向外迁移依然存在,主要迁往该地区内的目的地。与1999年相比,拥有安全土地保有权的家庭增多,从资产拥有情况衡量,家庭状况也有所改善。牧场持续增加,主要是以森林为代价。农场仍然是家庭重要的生计来源,不过NEA地区不断发展的城市正在创造更多非农业经济机会。我们的研究结果呈现了过去四分之一世纪NEA地区人口、经济、土地利用和生计变化的概况,为寻求平衡经济和环境目标以促进可持续发展并保护生物多样性的政策制定者提供了有用信息。
