We examine deforestation processes in Apuí, a deforestation hotspot in Brazil's state of Amazonas and present processes of land-use change on this Amazonian development frontier. Settlement projects attract agents whose clearing reflects land accumulation and the economic importance of deforestation. We used a mixed-method approach in the Rio Juma Settlement to examine colonization and deforestation trajectories for 35 years at three scales of analysis: the entire landscape, cohorts of settlement lots divided by occupation periods, and lots grouped by landholding size per household. All sizes of landholdings are deforesting much more than before, and current political and economic forces favoring the agribusiness sector foreshadow increasing rates of forest clearing for pasture establishment in Apuí. The area cleared per year over the 2013-2018 period in Apuí grew by a percentage more than twice the corresponding percentage for the Brazilian Amazon as a whole. With the national congress and presidential administration signaling impunity for illegal deforestation, wealthy actors, and groups are investing resources in land grabbing and land accumulation, with land speculation being a crucial deforestation factor. This paper is unique in providing causal explanations at the decision-maker's level on how deforestation trajectories are linked to economic and political events (period effects) at the larger scales, adding to the literature by showing that such effects were more important than aging and cohort effects as explanations for deforestation trajectories. Additional research is needed to deepen our understanding of relations between land speculation, illegal possession of public lands, and the expansion of agricultural frontiers in Amazonia.
我们研究了巴西亚马逊州阿普伊的森林砍伐过程,并展示了这片亚马逊发展前沿的土地利用变化过程。定居点项目吸引了代理人,他们的砍伐反映了土地积累和森林砍伐的经济重要性。我们在茹马定居点采用混合方法,在三个分析尺度上研究了 35 年来的殖民化和森林砍伐轨迹:整个景观、按居住时期划分的定居点批次以及按每户土地持有量分组的批次。所有规模的土地都在砍伐更多的森林,当前有利于农业综合企业部门的政治和经济力量预示着阿普伊地区为建立牧场而砍伐森林的速度将加快。阿普伊地区 2013 年至 2018 年期间每年砍伐的面积增长百分比超过巴西亚马逊地区的相应百分比。由于国会和总统政府对非法砍伐表示宽容,富有的行为者和团体正在投资土地掠夺和土地积累,土地投机是一个关键的森林砍伐因素。本文的独特之处在于,它在决策者层面提供了因果解释,说明森林砍伐轨迹如何与更大规模的经济和政治事件(时期效应)相关联,通过表明这些效应比老龄化和队列效应更能解释森林砍伐轨迹,为文献增添了新的内容。需要进一步研究,以加深我们对土地投机、非法占有公共土地以及亚马逊地区农业前沿扩张之间关系的理解。
