Cities are urged to promote green infrastructures to reduce their global environmental impacts, while simultaneously adapting to the global climatic variability that such impacts generate. Human Niche Construction theory, however, predicts evolutionary pressures acting over social groups that, this paper contends, tend to favor gray over green infrastructure. This conflict is due to competitive advantages of gray infrastructure, such as their higher capacity to concentrate and intensively use natural resources. Cities need to intentionally override these evolutionary pressures to allow emergence of regimes where green solutions are the normal way of responding to infrastructure-related challenges and development. The override calls for understanding how infrastructure regime dynamics are historically constructed, and cultivating collective intentions capable of harnessing such dynamics. After conceptualizing the roles of evolution versus collective intentionality in infrastructure regime dynamics, we apply Foucauldian genealogical analysis to critically understand how and why the superiority of gray infrastructure became naturalized as truth in Mexico City, Mexico. The analysis explores how gray infrastructure momentum was built over history and the sporadic emergence of collective intentions to break it. Findings show that shifting to a green- infrastructure-dominated regime in Mexico City today would benefit from strategies that simultaneously promote technical, political and subjective changes. Purely technical efforts to promote regime shifts are doomed to fail. Decentralization, democratization, and cultivating certain collective intentions are key factors to override evolutionary pressures. In the context of the anthropocene and growing recognition of the importance of artificially created environments, we remphasize subjectivity and intentionality.

敦促城市推广绿色基础设施，以减少其对全球环境的影响，同时适应此类影响所产生的全球气候变化。然而，人类生态位构建理论预测，作用于社会群体的进化压力，本文认为，相对于绿色基础设施，青睐灰色。该冲突是由于灰色基础设施的竞争优势所致，例如它们具有更高的集中和密集利用自然资源的能力。城市需要有意地克服这些进化压力，以允许出现绿色解决方案是应对基础设施相关挑战和发展的正常方式的政权。覆盖要求了解历史上如何构建基础架构动态，培养能够利用这种动力的集体意图。在概念化了进化相对于集体意图在基础设施制度动态中的作用之后，我们应用福柯族谱学分析来批判性地理解灰色基础设施的优势如何以及为什么在墨西哥墨西哥城被自然化为事实。该分析探讨了如何在历史上建立起灰色的基础设施势头，以及打破该势头的集体意图的零星出现。研究结果表明，今天在墨西哥城转向绿色基础设施为主的体制将受益于同时促进技术，政治和主观变革的战略。单纯地促进政权转变的技术努力注定会失败。权力下放，民主化，培养某些集体意愿是克服进化压力的关键因素。在人类世和对人工创造的环境的重要性的日益认识的背景下，我们强调主观性和故意性。
