Bugnot, A.B., Hose, G.C., Walsh, C.J., Floerl, O., French, K., Dafforn, K.A., Hanford, J., Lowe, E.C. and Hahs, A.K. (2019). Urban impacts across realms: Making the case for inter-realm monitoring and management. Science of the Total Environment, 648, 711–719.
An output from a workshop at the University of New South Wales aiming to further collaboration between ecologists working in terrestrial, freshwater and marine realms. In this paper, we discuss that the terrestrial realm is most commonly a ‘net-donor’ of impacts, as most human activities occur on land and the resulting impacts are transferred to aquatic and atmospheric realms (although impacts in the reverse direction also occur). We conclude that, to achieve effective management strategies, greater collaboration is needed between scientists and managers focussing on different realms and regions and we present suggestions for approaches to achieve this.

Of course they are running the line that the 50 gigalitres that the government have ordered from our desalination plant next summer is drawing on our insurance policy (that is costing us something like $600 million dollars a year before they turn it on, and substantially more for the water delivered, while…
One of the most common arguments I hear from a subset of urban water managers who don’t like rainwater tanks is that tanks are too unreliable to be considered a viable urban water source. So, perhaps now, a week after our tank lay empty for 8 days, would be a good…
Walsh and Webb (2013) developed a new index of stream condition, LUMaR*, based on their distribution models of 60 families of macroinvertebrates across the Melbourne region. The models allow prediction of the effects of loss (or gain) of forest cover and of conventionally drained urbanization on the occurrence of the 60 families….
In today’s update of my raingarden diary, I report on deliberately increasing our demand for water from our rainwater tank (by disabling the half-flush option on our toilets). Our increase in demand from our tank by 20–25 L a day might seem to go against everything our water authorities tell…
