In the midst of global change uncertainties, Indonesian spatial planning authorities are developing 20-year strategies. However, the lack of collaborative engagement of stakeholders and unclear methodology around using futures studies in addressing land management undermine such plans and affect environmental governance. A crucial question is how to link a future-oriented process with governance transformation processes, particularly related to land-use planning and management. To address this issue, we used a co-elaborative scenario-building approach, referred to as participatory prospective analysis (PPA), to facilitate the creation of local multistakeholder platforms considering future-oriented perspectives. The PPA design combines equally the knowledge of local communities, technical experts and decision-makers, and was applied in a series of sequential multistakeholder workshops in two regencies in Indonesia, followed by public consultations on the main results. In both regencies, participants agreed on a common topic related to spatial planning in their jurisdiction to be explored with a 20-year time horizon. They reached consensus on relevant variables, analyzed their dependence/influence, and developed several plausible yet contrasting scenarios for land management and road maps with guidelines for the implementation of desired outcomes. The PPA approach stimulated stakeholder engagement and ensured that more local voices were not only heard but also duly included in the process. It allowed participants to consider strategies that would otherwise have been less readily accepted by their respective organizations. It showed that it is possible to improve existing spatial planning processes in Indonesia by integrating tools for a more inclusive and long-term future-oriented collaborative approach.

在全球变化的不确定性中，印度尼西亚空间规划当局正在制定 20 年战略。然而，缺乏利益相关者的合作参与以及围绕使用未来研究解决土地管理问题的方法不明确，会破坏此类计划并影响环境治理。一个关键问题是如何将面向未来的流程与治理转型流程联系起来，尤其是与土地利用规划和管理相关的流程。为了解决这个问题，我们使用了一种共同制定的情景构建方法，称为参与式前瞻性分析 (PPA)，以促进考虑面向未来的视角创建本地多利益相关方平台。PPA 设计结合了当地社区、技术专家和决策者的知识，并被应用于印度尼西亚两个地区的一系列连续的多利益相关方研讨会，随后就主要结果进行了公众咨询。在这两个行政区，参与者就与他们管辖范围内的空间规划相关的一个共同主题达成了一致，该主题将在 20 年的时间范围内进行探索。他们就相关变量达成了共识，分析了它们的依赖性/影响，并为土地管理和路线图制定了几个看似合理但对比鲜明的情景，以及实施预期结果的指导方针。PPA 方法激发了利益相关者的参与，并确保不仅可以听到更多当地的声音，而且还可以适当地将其纳入流程中。它允许参与者考虑否则他们各自的组织不太容易接受的策略。
