Drawing on the Mukuru Special Planning Area in Nairobi (Kenya), this article analyses enabling conditions for scaling participatory planning in otherwise exclusionary urban political environments. It contributes to debates that focus on qualitative changes required to enhance citizen participation and on the integration of low-income residents’ needs, demands and innovations into city-wide planning practices around informal settlement upgrading. The article identifies three conditions that are key to enable and enhance the success of scaling efforts. First, moving to scale requires identifying, generating and making strategic use of political opportunities and building political momentum around them. Second, in addition to mobilizing, organizing and connecting stakeholders at different levels, successful scaling efforts must also promote qualitative changes in the way these stakeholders see themselves, and how they interact with and relate to each other. Third, going to scale requires the capacity to manage conflict successfully and prevent attempts to disrupt, co-opt or halt a scaling process.

本文以内罗毕（肯尼亚）内的Mukuru特别规划区为依据，分析了在其他排他性城市政治环境中扩大参与式规划的有利条件。它有助于辩论，辩论的重点是提高公民参与度所需的质变，以及将低收入居民的需求，要求和创新纳入围绕非正规住区升级的全市规划实践中。本文确定了三个条件，这些条件是启用和增强扩展工作成功的关键。首先，扩大规模需要确定，产生和战略利用政治机会，并在它们周围建立政治势头。其次，除了动员，组织和联系不同层次的利益相关者外，成功的扩展工作还必须促进这些利益相关者看待自己的方式以及彼此之间如何相互作用和联系的质变。第三，扩展规模需要具有成功管理冲突并防止破坏，协同或停止扩展过程的尝试的能力。
