Science-based stakeholder dialogue is a strategy to bring science closer to decision-making with increasing importance for the design of environmental policies. The need for such an approximation has been stressed, but documented implementations are rare. We present our experience of developing a science-based dialogue for the Brazilian Forest Code implementation and share the lessons learned. We departed from a mix of participatory methods to conduct six meetings with stakeholders. During the process, we were able to reduce the gap between science and practice, meeting stakeholders' expectations and increasing the accessibility of scientific information. Avoiding falling back to top-down science and keeping stakeholders' participation constancy were challenges faced. Despite the project achievements, important scientific outcomes were disregarded by higher instances of decision-making. Thus, although we were able to start the dialogue successfully, we also come across the fact that external political factors impaired its reach. By reporting our experience, we expect to help to establish science-based dialogues applied to environmental policy implementation, narrowing the science-practice gap and contributing to more effective environmental policies.

以科学为基础的环境政策实施利益相关者对话

以科学为基础的利益相关者对话是一种使科学更接近决策的战略，对环境政策的设计越来越重要。已经强调了对这种近似的需求，但很少有文档化的实现。我们介绍了我们为巴西森林法典实施开展基于科学的对话的经验，并分享了经验教训。我们放弃了多种参与式方法，与利益相关者举行了六次会议。在此过程中，我们能够缩小科学与实践之间的差距，满足利益相关者的期望并增加科学信息的可访问性。避免退回到自上而下的科学并保持利益相关者参与的稳定性是面临的挑战。尽管项目取得了成绩，重要的科学成果被更高级别的决策所忽视。因此，虽然我们能够成功地开始对话，但我们也遇到了外部政治因素削弱了对话影响的事实。通过报告我们的经验，我们希望帮助建立适用于环境政策实施的基于科学的对话，缩小科学实践差距并促进更有效的环境政策。
