A bioeconomic analysis of conserving freshwater values in an agricultural landscape

摘要: Water is a finite resource that must be shared among multiple users and economic conservation objectives can often seen as being in conflict. We explored this perception by conducting an integrated bioeconomic analysis of irrigated agriculture the freshwater attributes agricultural landscape, Tasmanian Midlands. constructed simple model based on current hydrology, water allocation, land use ecosystem values, quantified returns from irrigation under range future climate, development scenarios. found projected climate conditions conserving values good condition had small effects to irrigators, enterprise diversity area were major drivers landscape. The availability suitable for rather than itself appeared most likely limit future. provide multi-criteria comparing scenarios at regional scale inform planning decision making natural management. Our approach brings concerns into same context demonstrates need not necessarily development.
