Method for estimating the social sustainability of infrastructure projects

Niigata soil liquefaction. Wikipedia

La evaluación de la sostenibilidad social de los proyectos no es un tema sencillo ni inmediato. Si bien los impactos medioambientales se han estudiado en el ámbito científico con cierta profundidad, los impactos sociales de las infraestructuras se han investigado mucho menos. Es más, en numerosas ocasiones dichos impactos se han minusvalorado. Pues bien, nos acaban de publicar un artículo en la revista Environmental Impact Assessment Review (revista indexada en el JCR, primer cuartil de impacto) en el cual proponemos una metodología que permite afrontar este reto.

Highlights:

  • Method to select suitable infrastructure projects from the social sustainability point of view
  • Emphasizes social interactions of the infrastructure in the short and long term
  • Distinguishes the social sustainability of infrastructure projects in different locations
  • Efficiency of a social contribution in terms of early social benefits and a long-term distribution
  • Supports early decision-making of public agencies regarding infrastructure projects

 

Abstract:

Nowadays, sustainability assessments tend to focus on the biophysical and economic considerations of the built environment. Social facets are generally underestimated when investment in infrastructure projects is appraised. This paper proposes a method to estimate the contribution of infrastructure projects to social sustainability. This method takes into account the interactions of an infrastructure with its environment in terms of the potential for short and long-term social improvement. The method is structured in five stages: (1) social improvement criteria and goals to be taken into account are identified and weighed; (2) an exploratory study is conducted to determine transfer functions; (3) each criterion is homogenized through value functions; (4) the short and long-term social improvement indices are established; and finally, (5) social improvement indices are contrasted to identify the socially selected alternatives and to assign an order of priority. The method was implemented in six alternatives for road infrastructure improvement. The results of the analysis show that the method can distinguish the contribution to social sustainability of different infrastructure projects and location contexts, according to early benefits and potential long-term equitable improvement. This method can be applied prior to the implementation of a project and can complement environmental and economic sustainability assessments.

Social Sustainability in the Lifecycle of Chilean Public Infrastructure

Leonardo A. Sierra. Instructor, Dpto. Ingeniería de Obras Civiles, Universidad de La Frontera, Francisco Salazar

ABSTRACT:

To enhance concern for the social aspects of sustainability and to delineate the criteria to be considered at each stage of the lifecycle of an infrastructure, this paper aims to determine the relevance of a set of criteria that evaluate social sustainability throughout the lifecycle of a public civil infrastructure. This research presents the results of a case study applying the Delphi method to 24 Chilean experts consulted in a series of three rounds. In addition, binomial statistical tests and Kendall’s coefficient were used to show the convergence of the experts. Thus, it was identified that of 36 initial criteria assessed at each stage of the lifecycle, the consideration of 20 is required at the design stage, 29 at the construction stage, 33 during operation, and 27 at demolition. The most relevant criteria, per lifecycle stage, were Stakeholder Participation (design and demolition stages), External Local Population (design stage), Internal Human Resources (construction and demolition stages), Macro-Social Action of Socioenvironmental Activities (construction stage), and Macro-Social Action of Socioeconomic Activities (operation stage). – See more at: http://ascelibrary.org/doi/abs/10.1061/(ASCE)CO.1943-7862.0001099#sthash.Uryrzju5.dpuf
