South America's Tri-national Paraná Atlantic Forest, an ecological region spanning across the nations of Argentina, Brazil and Paraguay, is one of the most diverse in the world but also one of the most vulnerable to deforestation. A review of public policy interventions shows all three governments have taken major legislative steps to protect remaining forests, but studies evaluating deforestation trends and associated factors in this region are scarce or non-existent. Here, we make a direct contribution to this knowledge gap by assessing deforestation trends within Paraná Atlantic forests of Argentina's Misiones, Brazil's Paraná, and Paraguay's Alto Paraná between 2000 and 2020. Over this period about 20% of forest cover was lost in Misiones, 13% in Paraná, and 18% in Alto Paraná. The odds of observed deforestation, else constant, showed nuanced associations with proximity to nearest roads, cities, and ports. Higher levels of economic growth were directly associated with deforestation, as were increases in population density over the entire period. Protected area designation between years 2000 and 2020 showed effectiveness in lowering odds of deforestation with heterogeneous associations across countries. Our results reflect associational inferences with estimated deforestation; future research should investigate causal effects of protected designation, and assess its role in avoided degradation and wider socio-economic impacts.

南美洲三国巴拉那大西洋森林的森林砍伐:趋势和关联因素

南美洲的三国巴拉那大西洋森林是一个横跨阿根廷、巴西和巴拉圭国家的生态区,是世界上最多样化的地区之一,也是最容易受到森林砍伐的地区之一。对公共政策干预措施的审查表明,所有三个政府都已采取重大立法措施来保护剩余的森林,但评估该地区森林砍伐趋势和相关因素的研究很少或不存在。在这里,我们通过评估 2000 年至 2020 年间阿根廷米西奥内斯、巴西巴拉那州和巴拉圭上巴拉那州巴拉那大西洋森林的森林砍伐趋势,为这一知识差距做出了直接贡献。在此期间,米西奥内斯失去了约 20% 的森林覆盖率,13巴拉那州 %,上巴拉那州 18%。观察到森林砍伐的几率,否则不变,显示出与最近的道路、城市和港口的接近程度的细微关联。更高水平的经济增长与森林砍伐直接相关,整个时期人口密度的增加也是如此。2000 年至 2020 年之间的保护区指定显示出在降低不同国家之间存在异质性关联的森林砍伐几率方面的有效性。我们的结果反映了与估计的森林砍伐的关联推断;未来的研究应调查受保护名称的因果影响,并评估其在避免退化和更广泛的社会经济影响方面的作用。2000 年至 2020 年之间的保护区指定显示出在降低不同国家之间存在异质性关联的森林砍伐几率方面的有效性。我们的结果反映了与估计的森林砍伐的关联推断;未来的研究应调查受保护名称的因果影响,并评估其在避免退化和更广泛的社会经济影响方面的作用。2000 年至 2020 年之间的保护区指定显示出在降低不同国家之间存在异质性关联的森林砍伐几率方面的有效性。我们的结果反映了与估计的森林砍伐的关联推断;未来的研究应调查受保护名称的因果影响,并评估其在避免退化和更广泛的社会经济影响方面的作用。
