This paper presents and discusses the use of methodologies for shared and participatory planning through Geodesign, in areas of irregular occupation and social vulnerability in the urban areas of the Iron Quadrangle, Minas Gerais, Brazil. It is illustrated by the development of four case studies with varying degrees of complexity, participation, and impact as a support for opinion building or decision making. The work encompasses different applications of digital support platforms, from web-based to off-line, as well as their methodological variations, adopted according to the goals of each case study. They vary according to space, the profile of the participants (ages), technological platform, methodological steps, but they all share support for opinion making. We conclude by suggesting optimal methodological choices for different contexts of social vulnerability, regarding the evolution of urban planning processes. We argue in favor of Geodesign as a framework for the planning of irregular housing occupations, as it is flexible enough to deal with different scenarios.

巴西米纳斯吉拉斯州铁四边形社会脆弱地区的地理设计实验

本文介绍并讨论了在巴西米纳斯吉拉斯州 Iron Quadrangle 城市地区的非正常职业和社会脆弱地区通过地理设计进行共享和参与式规划的方法的使用。它通过四个具有不同程度的复杂性、参与度和影响力的案例研究的发展来说明，作为对意见建立或决策的支持。这项工作包括数字支持平台的不同应用，从基于网络到离线，以及根据每个案例研究的目标采用的方法变化。它们因空间、参与者的概况（年龄）、技术平台、方法步骤而异，但它们都支持意见制定。最后，我们就城市规划过程的演变提出了针对不同社会脆弱性背景的最佳方法选择。我们赞成将地理设计作为规划不规则住房占用的框架，因为它足够灵活以应对不同的情况。
