| Shortfalls in water supplies are perhaps the greatest practical NRM policy concern in Australia today, looming larger in many minds than the great international debates on greenhouse gasses, climate change and biodiversity. Because forest land cover uses more water than any other, wide expansion of upstream tree plantations can significantly reduce water yields upon which downstream urban, agricultural and wetlands depend. We consider the economic efficiency and equity (profitability and distributional) consequences of upstream land use change. The ‘environmental services’ of concern in our study are the mean annual quantities and qualities (volumes and salt concentrations) of water flowing from upper parts of a catchment to the downstream interests... |

| The net present value (NPV) of downstream economic benefits of changes in water-yield (W) and salt-load (S) of mean annual river flow received by a lower catchment from an upper catchment are described as a 3-dimensional (NPV,W, S) surface, where dNPV/dW > 0 and dNPV/d(S/W) < 0. Upstream changes in land use (i.e. forest clearing or forest establishment, which result in higher or lower water-yields, respectively) are driven by economic consequences for land owners. This paper defines conditions under which costs of strategic upstream land use changes could be exceeded by compensations afforded by downstream benefits from altered water-yields and/or lower salt loads. The paper presents methods, and preliminary calculations for an example river,... |
