Rethinking urban water management: Experimentation as a way forward?

There is widespread acceptance regarding the need to transition towards more sustainable urban water practices. Supporting such a transition requires new governance frameworks that can accommodate complexity and uncertainty, and organisational cultures that embrace experimentation and learning. This empirically focused research paper examines how eleven, alternative local-scale experiments were initiated while operating in an unsympathetic regime. Furthermore, the perceptions of more than 150 urban water practitioners across Australia are presented, regarding the importance of and difficulty in undertaking experimentation in the urban water sector, and the necessary mechanisms for influencing a step change to sustainable urban water management practices. Interviewees revealed perceived limitations in experimenting with new technologies and practices when operating within a hierarchical and market-based governance paradigm. Also, industry conservatism and the dominant risk-based management approach both operate as significant constraints to promoting an experimentation culture, and are closely related to concerns about public health and financial implications. Overall, the research highlights the Australian urban water sector is willing to embrace learning-by-doing; however, a stronger emphasis on promoting an organisational and industry-wide culture of experimentation and learning is required. Policy implications for future water governance are discussed.     

Fisheries mismanagement

We analysed the extent to which European politicians have adhered to scientific recommendations on annual total allowable catches (TACs) from 1987 to 2011, covering most of the period of the Common Fisheries Policy (CFP). For the 11 stocks examined, TACs were set higher than scientific recommendations in 68% of decisions. Politically-adjusted TACs averaged 33% above scientifically recommended levels. There was no evidence that the 2002 reform of the CFP improved decision-making, as was claimed at the time. We modelled the effects of such politically-driven decision-making on stock sustainability. Our results suggest that political adjustment of scientific recommendations dramatically increases the probability of a stock collapsing within 40 years.In 2012 European fisheries policy will undergo a once-a-decade reform. Ten years ago radical reforms were promised but the changes failed to improve sustainability. It is likely that the 2012 reform will be similarly ineffective unless decision-making is changed so that catch allocations are based on science rather than politics.
