The 2012 Brazilian Forest Code governs the fate of forests and savannas on Brazil's 394 Mha of privately owned lands. The government claims that a new national land registry (SICAR), introduced under the revised law, could end illegal deforestation by greatly reducing the cost of monitoring, enforcement, and compliance. This study evaluates that potential, using data from state-level land registries (CAR) in Pará and Mato Grosso that were precursors of SICAR. Using geospatial analyses and stakeholder interviews, we quantify the impact of CAR on deforestation and forest restoration, investigating how landowners adjust their behaviors over time. Our results indicate rapid adoption of CAR, with registered properties covering a total of 57 Mha by 2013. This suggests that the financial incentives to join CAR currently exceed the costs. Registered properties initially showed lower deforestation rates than unregistered ones, but these differences varied by property size and diminished over time. Moreover, only 6% of registered producers reported taking steps to restore illegally cleared areas on their properties. Our results suggest that, from the landowner's perspective, full compliance with the Forest Code offers few economic benefits. Achieving zero illegal deforestation in this context would require the private sector to include full compliance as a market criterion, while state and federal governments develop SICAR as a de facto enforcement mechanism. These results are relevant to other tropical countries and underscore the importance of developing a policy mix that creates lasting incentives for sustainable land-use practices.
2012 年巴西森林法规定了巴西 3940 万公顷私人土地上的森林和稀树草原的命运。政府声称,根据修订后的法律引入的新国家土地登记处(SICAR)可以通过大大降低监测、执法和合规成本来结束非法毁林现象。本研究利用 SICAR 的前身帕拉州和马托格罗索州的州级土地登记处(CAR)的数据来评估这种潜力。我们利用地理空间分析和利益相关者访谈,量化了 CAR 对毁林和森林恢复的影响,调查了土地所有者如何随着时间的推移调整他们的行为。我们的结果表明,CAR 得到了迅速采用,到 2013 年,已登记的财产总面积达到 5700 万公顷。这表明,加入 CAR 的经济激励目前超过了成本。登记财产最初的毁林率低于未登记财产,但这些差异因财产规模而异,并随着时间的推移而减少。此外,只有 6%的登记生产者报告采取措施恢复其财产上非法砍伐的区域。我们的结果表明,从土地所有者的角度来看,完全遵守森林法并没有带来多少经济利益。在这种情况下,要实现零非法毁林,私营部门需要将完全遵守作为一个市场标准,同时州和联邦政府将 SICAR 发展成为事实上的执法机制。这些结果与其他热带国家有关,强调了制定一个政策组合的重要性,该政策组合为可持续土地利用实践创造持久的激励。
