There is evidence that suggests that both the creation of Protected Areas (PAs) and indigenous Reserves (IRs) has helped to reduce deforestation. Nevertheless, there are some overlapping zones between these institutions in the Colombian Amazon that have not been studied. Are these overlaps affecting the deforestation in the IRs? How are the indigenous communities responding to these overlaps? In this paper I estimate the impacts of these overlaps on the deforestation inside the IRs using a Propensity Score Matching (PSM) methodology. I use important determinants of the location of PAs and deforestation to create a valid counterfactual within the IRs. My results suggest that the overlap significantly reduces the deforestation, but that there is a differential effect depending on the IR's size. These results suggest that the extra legal restriction imposed by the central government favor the territorial control inside the IRs. This paper provides a starting point to analyze the current relationship between the central government, the indigenous communities and how it affects deforestation.

有证据表明，保护区 (PA) 和土著保护区 (IR) 的建立都有助于减少森林砍伐。尽管如此，哥伦比亚亚马逊地区的这些机构之间仍有一些尚未研究的重叠区域。这些重叠是否会影响 IR 中的森林砍伐？土著社区如何应对这些重叠？在本文中，我使用倾向评分匹配 (PSM) 方法估计了这些重叠对 IR 内部森林砍伐的影响。我使用 PA 位置和森林砍伐的重要决定因素在 IR 中创建有效的反事实。我的结果表明重叠显着减少了森林砍伐，但根据 IR 的大小存在不同的影响。这些结果表明，中央政府施加的额外法律限制有利于 IR 内部的领土控制。本文提供了一个分析中央政府、土著社区之间当前关系及其对森林砍伐的影响的起点。
