Urban regeneration strategy for shrinking neighborhoods: A case study of Gyo-Byu water pipeline, Yangon

Abstract

In recent years, linear infrastructure has become a critical element in shaping urban neighborhoods, particularly in developing countries where neighborhoods near such infrastructure often face significant challenges, such as urban shrinkage. In Yangon, the presence of colonial-era linear infrastructure, such as the Gyo-Byu water pipeline, plays a vital role in the city's core development and contributes to the identity of the urban fabric. This study investigates the urban vulnerability faced by neighborhoods along the Gyo-Byu water pipeline, analyzing the context of shrinking neighborhoods and exploring key challenges that neighbors encounter. It employs a phenomenological approach, grounded in multi-qualitative neighborhood assessment methods, including field observation, on-the-spot interviews, focus group discussion, institutional data analysis, and spatial neighborhood mapping. Interview data was analyzed using reflexive thematic method by MAXQDA software. The study focuses on three core aspects: the relationship between linear infrastructure and neighborhood dynamics, key neighborhood problems, and local priorities and aspirations of neighborhood regeneration needs. Findings highlight that neighborhood social fragmentation and livability challenges, multidimensional barriers to business viability, neighborhood environmental degradation and lack of green infrastructure present major challenges for surrounding neighborhoods of Gyo-Byu water pipeline. Furthermore, the research found that Gyo-Byu water pipeline as neighborhood identity and dual-role linear infrastructure assets. In response, the research proposes three-approaches strategies to urban acupuncture regeneration framework that emphasizes infrastructure improvement, community development, and sustainability. This research provides valuable tools for policymakers and urban stakeholders, offering targeted strategies for revitalizing shrinking urban neighborhoods through sustainable infrastructure and community development.
