This paper examines the assumption that redevelopment of slum settlements results in improved housing quality, by conducting a longitudinal study of an in-situ redevelopment policy in Ahmedabad, India. Under an in-situ redevelopment policy, apartment-style housing is built on the same site of original slum settlements. This paper examines housing quality in the same settlement, pre- and post-redevelopment, in comparison to a wait-listed slum that did not undergo redevelopment, to ascertain redevelopment impact on housing quality. It further compares housing quality of a resettled community at two time periods, 2.5- and 8.5-years post-redevelopment to determine durability of housing quality changes over medium-term. I use a mixed-methods protocol employing a standardized observer-based housing quality assessment tool with subscales, to identify specific aspects of housing quality that improved/deteriorated and gathered qualitative data from interviews and focus groups. The analyses reveal an improvement in overall housing conditions post-redevelopment, in the short term, though this improvement is not uniform across subscales. However, this improvement does not sustain as redeveloped settlement shows severe levels of deterioration over mid-term. The qualitative findings suggest that in redeveloped settlements, residents feel a diminished sense of control and ownership that precludes them from investing in structural improvements and maintenance of settlements.

本文通过对印度艾哈迈达巴德的原地再开发政策进行纵向研究，检验了贫民窟再开发可提高住房质量的假设。在原地重建政策下，公寓式住房建在原来的贫民窟定居点的同一地点。本文通过与未进行再开发的候补贫民窟进行比较，研究了同一居住区、重建前和重建后的住房质量，以确定重建对住房质量的影响。它进一步比较了重新安置社区在重建后 2.5 年和 8.5 年两个时间段的住房质量，以确定中期住房质量变化的持久性。我使用混合方法协议，采用标准化的基于观察者的住房质量评估工具和子量表，确定改善/恶化的住房质量的具体方面，并从访谈和焦点小组收集定性数据。分析表明，在短期内，重建后整体住房条件有所改善，尽管这种改善在各个子尺度上并不统一。然而，这种改善并没有持续下去，因为重建的定居点在中期表现出严重的恶化水平。定性研究结果表明，在重新开发的定居点中，居民的控制感和所有权感减弱，这使他们无法投资于结构改进和定居点维护。在短期内，尽管这种改进在各个子尺度上并不统一。然而，这种改善并没有持续下去，因为重建的定居点在中期表现出严重的恶化水平。定性研究结果表明，在重新开发的定居点中，居民的控制感和所有权感减弱，这使他们无法投资于结构改进和定居点维护。在短期内，尽管这种改进在各个子尺度上并不统一。然而，这种改善并没有持续下去，因为重建的定居点在中期表现出严重的恶化水平。定性研究结果表明，在重新开发的定居点中，居民的控制感和所有权感减弱，这使他们无法投资于结构改进和定居点维护。
