Local infrastructure governance in Peru: a systems thinking appraisal

Abstract

Ensuring the through-life quality of infrastructure systems is a fundamental instrument in providing economic development and enhancing the quality of life. The complexity of infrastructure networks themselves, the operations of the public entities that manage them and the governance systems that oversee them make this a challenging activity. This research uses the city of Arequipa in Peru as a case study to bridge the knowledge gap on the behaviour of such municipalities regarding the management of infrastructure systems. It employs qualitative system dynamics modelling through a methodology based on the V-model, with its emphasis on validation and verification, and framed in the systems thinking approach. First, 67 variables characterising the management of infrastructure systems in Arequipa are identified from the literature and semi-structured interviews with key actors. Second, a model of the system is constructed using causal loop diagrams. Within this model, 33 feedback loops are identified, formed from the causal influences between variables. Third, a diagnosis is carried out that unequivocally illuminates the failure patterns of the municipalities. Fourth, by identifying leverage points, a paradigm-shifting intervention is proposed along with tools that municipalities can implement to improve their performance. Finally, these proposals are validated with key actors through a focus group.
