Contestations over Scale Frames regarding the Sustainability of Mega-infrastructure Project Development

The case of the Bali Mandara Highway

Abstract

Some urban megaprojects are framed as a strategic move to achieve broader economic benefits. Project proponents often claim that adverse socio-environmental effects are mitigated accordingly and that all aspects of sustainability are integrated successfully. Using a case study of the Bali Mandara highway, this study drew upon the politics of scale to investigate multiple frames of these effects and mitigation efforts on various scales (and levels). Semi-structured interviews were conducted, and secondary data sources were collected to explore and examine the variety and mix of the scale frames representing all sustainability aspects. Words and phrases related to scale-related issues were identified and tracked in the development phases (i.e., pre-construction, construction, and usage). The study shows that different stakeholders used specific preferred scale types to frame the effects and mitigation efforts, and these frames evolved throughout the project phases. Our findings substantiate that limited scale choices can occur from a lack of open process, resulting in a limited representation of all scale-related issues affecting the sustainability of the highway project development. This paper adds insights into the use of scale to explore the broad effects of urban megaprojects and calls for more transparent and accountable impact audits.
