Studies that apply indigenous ecological knowledge to contemporary resource management problems are increasing globally; however, few of these studies have contributed to environmental water management. We interviewed three indigenous landowning groups in a tropical Australian catchment subject to increasing water resource development pressure and trialed tools to integrate indigenous and scientific knowledge of the biology and ecology of freshwater fish to assess their water requirements. The differences, similarities, and complementarities between the knowledge of fish held by indigenous people and scientists are discussed in the context of the changing socioeconomic circumstances experienced by indigenous communities of north Australia. In addition to...

ABSTRACT Physical habitat simulation (PHABSIM) is an important step of the instream flow incremental methodology (IFIM), which is applied to establish environmental flow regimes. This study applied the PHABSIM in two reaches of the Velhas river basin, whose long-term discharges are similar but are under different degrees of impact. Suitability curves were obtained for fish species using traditional methods (Astyanax sp., Piabarchus stramineus, Piabina argentea and Serrapinnus heterodon) and generalized additive models for fish density (Astyanax sp., P. argentea and S. heterodon). The results of habitat use depended on the method for curves generation. Applying the suitability curves by traditional methods, different discharge scenarios were simulated. The...

Environmental flow allocation and counter-cyclical trading in the River Murray System

Autores: English,   Ben; Brearley,   Taron; Coggan,   Anthea.
Australia's climate is characterized by highly variable rainfall. As a consequence, many aspects of riverine ecosystems need both very wet and very dry periods to function effectively. This contrasts with water demands from industrial and agricultural sectors, which place a premium on access to a constant supply of water. This combination of demands suggests there could be considerable value in using water banking and trading mechanisms to reduce the social cost of achieving environmental objectives. In this paper, the concept of counter-cyclical trading is outlined and influences on its potential for reducing the cost of achieving environmental flow objectives evaluated. The potential value of using mechanisms to enable counter-cyclical trading across low...
