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...

It is commonly noted that Australian water rights, specifically those prevailing within the Murray-Darling Basin, represent a significant departure from hydrological reality (see for example Young and McColl 2009). Where water rights depart from the physical realities of water supply networks,...

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...

With the increase in cost of surface water, groundwater extraction for irrigation has become more competitive. Due to the interdependence of different water resources in a catchment, the management of all water resources should be integrated. An illustrative model is formulated of the dynamic...

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...

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...

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...

It is commonly noted that Australian water rights, specifically those prevailing within the Murray-Darling Basin,represent a significant departure from hydrological reality (see for example Young and McColl 2009). Where waterrights depart from the physical realities of water supply networks,...

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...
