Analysis and application of international dam safety policy benchmarks

Abstract

Purpose: Farm dam safety in Australia is being flouted and sustainability of catchments compromised because of the potential and severe consequences of dam failure. Hence, the purpose of this paper is to explore policy issues associated with safety of farm dam water storage through a comparison of developments in two Australian states against an analysis of international benchmarks and to provide an exemplar of best practice. Design/methodology/approach: A strategic review and content analysis is firstly undertaken to establish international dam safety policy benchmarks ranging from minimum to best practice as well as selection guidelines for varying circumstances, and to identify an exemplar best practice model. Longitudinal study over a 12-year period then provides the basis for case analysis in order to reinforce the established minimum level benchmark and to demonstrate the application of the benchmarked model policy selection guidelines. Findings: Research results show that in Australia, South Australia is lagging international benchmarks for on-farm dam safety management in a number of ways whilst a second state, Tasmania, provides leadership in this respect. The paper adds to the existing international benchmarking literature by identifying updated international best practice in private/farm dam safety assurance policy whilst establishing and providing longitudinal case study reinforcement for an acceptable minimum level benchmark in this area. The updated policy guidelines presented can be used to determine appropriate dam safety policy for any jurisdiction. Originality/value: The paper provides an original contribution of analysis, establishment and case study validation of international benchmarks and guidelines on developing appropriate dam safety management and assurance policy for varying jurisdictional circumstances. In addition, it provides an updated exemplar of how policy benchmarks can go towards addressing cumulative threats of smaller dams in catchments not previously addressed.
