More and more people move to cities, urban areas become denser, space more scarce. As a consequence, house prices increase, leading to gentrification and displacement in city centres. At the same time, there is untapped potential for densification in suburban areas. Such suburban densification bears the potential of alleviating the negative consequences of housing shortage. In addition, densification is considered critical by urban planning to tackle climate change mitigation and adaptation by reducing net land uptake. But suburban densification is tricky as it meets plural rationalities of space, actors, and policies. Plural rationalities of space entail that suburban areas are socially constructed - conceived - by its landowners not by one logic, but multiple conceptions of space - space as territory, as economic asset, as social status, etc - coexist. In addition, there is often strong resistance to change in suburban areas, impeding the implementation of densification. Such resistance stems from different interpretations of densification by actors - i.e. landowners and local stakeholders. Furthermore, suburban densification policy by national or urban planning meets locationally specific politics of space. Public policy interventions in land – land policy – that does not take into account these plural rationalities of policy are deemed to fail. This project seeks to better understand the polyrationalities of space, actors and policies on suburban densification. It will explore how diverse strategies of land policy interact with landowners’ and local stakeholders’ interest and agency to shape suburban densification and their impact on suburbia across different planning systems. There are methodological and theoretical challenges with this aim of the project. Densification processes are analyzed in-depth in case studies. To explore polyrationalities, data science and spatial analysis is combined in this project with socio-anthropological approaches (Cultural Theory) and spatial planning across different institutional contexts. Such an endeavour implies to combine knowledge, methodologies and theories from different disciplines, able to reveal polyrationalities of each element alone - space, actors, and policies - and in combination. Ultimately, SUBDENSE combines geospatial and socio-demographic data to analyse and inform on polyrationalities. This entails to assess and enhance the fitness of data for comparative analysis of understanding densification phenomena on the ground as well as for communication and decision-making in a densification dashboard.

越来越多的人搬到城市，城市地区变得更加密集，空间更加稀缺。因此，房价上涨，导致城市中心的中产阶级化和流离失所。与此同时，郊区的致密化潜力尚未开发。这种郊区密集化有可能缓解住房短缺的负面影响。此外，城市规划认为，密集化对于通过减少净土地占用来缓解和适应气候变化至关重要。但郊区的密集化是棘手的，因为它符合空间，演员和政策的多元理性。空间的多元合理性意味着郊区是由土地所有者以社会的方式构建的，而不是按照一种逻辑，而是多种空间概念--作为领土、经济资产、社会地位等的空间--共存。此外，在郊区往往存在强烈的变革阻力，阻碍了密集化的实施。这种抵制源于行为者-即土地所有者和当地利益攸关方-对致密化的不同解释。此外，国家或城市规划的郊区密集化政策符合特定地点的空间政治。土地方面的公共政策干预-土地政策-如果没有考虑到政策的这些多元理性，就被认为是失败的。该项目旨在更好地理解郊区密集化的空间、行为者和政策的多元性。它将探讨土地政策的不同战略如何与土地所有者和当地利益攸关方的利益和机构相互作用，以塑造郊区密集化及其对不同规划系统的哥伦比亚的影响。该项目的这一目标在方法和理论上存在挑战。在案例研究中对致密化过程进行了深入分析。为了探索多元理性，该项目将数据科学和空间分析与社会人类学方法（文化理论）和不同制度背景下的空间规划相结合。这一努力意味着要将不同学科的知识、方法和理论联合收割机结合起来，能够揭示每一个要素-空间、行为者和政策-本身以及结合起来的多理性。最终，SUBDENSE结合了地理空间和社会人口数据，以分析和提供有关多元理性的信息。这就需要评估和加强数据的适用性，以便对实地的致密化现象进行比较分析，并在致密化仪表板中进行交流和决策。
