Valoración de la contribución de una infraestructura a la sostenibilidad social bajo condiciones de incertidumbre

Nos acaban de publicar en la revista de Elsevier del primer cuartil, Environmental Impact Assessment Review, un artículo donde se valora la contribución de una infraestructura a la sostenibilidad social bajo condiciones de incertidumbre. Este artículo forma parte de nuestra línea de investigación BRIDLIFE en la que se pretenden optimizar estructuras atendiendo no sólo a su coste, sino al impacto ambiental y social que generan a lo largo de su ciclo de vida.

Abstract:

Assessing the viability of a public infrastructure includes economic, technical and environmental aspects; however, on many occasions, the social aspects are not always adequately considered. This article proposes a procedure to estimate the social sustainability of infrastructure projects under conditions of uncertainty, based on a multicriteria deterministic method. The variability of the method inputs is contributed by the decision-makers. Uncertain inputs are treated through uniform and beta PERT distributions. The Monte Carlo method is used to propagate uncertainty in the method. A case study of a road infrastructure improvement in El Salvador is used to illustrate this treatment. The main results determine the variability of the short and long-term social improvement indices by infrastructure and the probability of the position in the prioritization of the alternatives. The proposed mechanism improves the reliability of the decision making early in infrastructure projects, taking their social contribution into account. The results can complement environmental and economic sustainability assessments.

Propuesta metodológica para estimar la sostenibilidad social de los proyectos de ingeniería

Terremoto en Chile. 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.
