In 2012, the Brazilian government revised the federal Forest Code that governs the use of forest resources on rural properties. The revisions included a forest trading mechanism whereby landowners who deforested more than what is legally allowed before 2008 could absolve their deforestation "debts" by purchasing Environmental Reserve Quotas (CRA) from landowners who conserved more forest than legally required. CRA holds promise as a tool to complement command-and-control initiatives to reduce deforestation and incentivize restoration. However, the success of this instrument depends on how its implementation is governed. This study builds on a few recent assessments of the potential of the CRA in Brazil-but that are focused on biophysical potential-by assessing how a few key implementation decisions may influence the CRA market development. Specifically, this study estimates how decisions on who can participate will likely influence the potential forest surplus and forest debt for the CRA market, and takes into account governance characteristics relevant to the State of Pará, eastern Amazonia. In particular, the study evaluates the effects in the CRA market eligibility after simulating a validation of properties in the environmental rural registry (CAR) and assessing different scenarios surrounding land tenure status of properties. Results show how regulatory decisions on CRA market eligibility will determine the extent to which CRA will serve as a tool to support forest conservation or as a low-cost path to help illegal deforesters to comply with legislation, but with limited additional environmental benefits. The study reviews regulatory options that would reduce the risk of forest oversupply, and thereby increase the additionality of the areas eligible for CRA. Overall, the study demonstrates the importance of including governance as well as biophysical characteristics in assessing the potential of forest trading tools to deliver additional environmental conservation and restoration benefits.
2012年,巴西政府修订了管理农村土地森林资源使用的联邦森林法。修订内容包括一种森林交易机制,即那些在2008年之前砍伐森林超过法定允许量的土地所有者,可以通过从森林保护量超过法定要求的土地所有者那里购买环境储备配额(CRA)来免除其砍伐森林的“债务”。CRA有望成为一种补充命令与控制措施以减少森林砍伐并激励森林恢复的工具。然而,该工具的成功与否取决于其实施方式。本研究在近期对巴西CRA潜力的一些评估基础上——但那些评估侧重于生物物理潜力——通过评估一些关键的实施决策可能如何影响CRA市场发展。具体而言,本研究估计关于谁可以参与的决策可能如何影响CRA市场的潜在森林盈余和森林债务,并考虑与亚马孙东部帕拉州相关的治理特征。特别是,该研究在模拟环境农村登记处(CAR)中财产验证并评估围绕财产土地保有权状况的不同情景后,评估对CRA市场资格的影响。结果表明,关于CRA市场资格的监管决策将决定CRA在多大程度上作为支持森林保护的工具,或者作为帮助非法砍伐者遵守法律的低成本途径,但带来的额外环境效益有限。该研究审查了可降低森林供应过剩风险的监管选项,从而增加符合CRA资格的区域的额外性。总体而言,该研究表明在评估森林交易工具实现额外环境保护和恢复效益的潜力时纳入治理以及生物物理特征的重要性。
