In a dynamic bio-economic multi-cohort analysis of fishing for a long lived species there can be a significant terminal value problem. The way this problem is dealt with can have a significant bearing on optimal policy recommendations. In this study, a bio-economic model of the Southern Bluefin...

Australian urban water utilities face a significant challenge in designing appropriate demand management and supply augmentation policies in the presence of increasing water scarcity and uncertainty over future dam inflows. This paper considers the design of optimal demand management and supply...

A model of the Murrumbidgee Irrigation Area with two linked components: the farms in the area and the off farm water delivery system is developed. Two versions of the model are formulated. The first version represents the practice of uniform pricing by water authorities where the differences in...

Australian governments have agreed to develop and implement policies to promote more efficient use of water resources and improved water quality. Policy objectives may include incentives for investment in efficient irrigation technologies. However, the presence of large, sunk investment and the...

Most urban centres across Australia are facing water shortages. In part, these water shortages are due to the variability of supply and demand caused by variable climatic conditions. Permanent supply augmentation to meet periodic water shortages can be costly. Water trade between rural and urban...

Australian urban water utilities face a significant challenge in designing appropriate demand management and supply augmentation policies in the presence of significant water scarcity and climate variability. This article considers the design of optimal demand management and supply augmentation...

Chinese grasslands are suffering considerable pressures from human and livestock populations. It has been estimated that 90% of Chinese grasslands are suffering from light to heavy levels of degradation. Allied to this is the low household income of herders and farmers dependant upon livestock...

This paper analyses a fisheries management strategy, marine reserves switching, in which a non-fishing area is created, removed, or rotated from one site to another according to economic criteria through time. Using a dynamic optimisation framework under uncertainty, with the different fish...

A choice modelling valuation exercise was recently undertaken across several countries to assess the tradeoffs that households are prepared to make between water use restrictions, maintaining environmental condition in waterways, and increased water costs. The results from the Queensland survey...
