The large, unutilised native forest timber resource on traditional Wik land on Cape York Peninsula, Australia, could be managed for timber production to contribute to Wik socio-economic objectives. Wik elders have a set of forestry objectives and envisage that these will be best achieved by a...

The economic impacts of altering quarantine policies are divided into two main areas: trade evaluations, utilising a partial equilibrium approach to determine the benefits of market liberalisation; or pest management economics, used to determine the on-ground impacts of introduced species. This...

The long-term success of the Basin Plan and the Buy-Back will be judged by the capacity of the allocated public funding to deliver water to the environment, potable water supplies for the community and water for irrigation. Water property rights in the Murray-Darling Basin can be divided into...

Abstract: The precautionary principle has been proposed as a basis for making decisions about envi- ronmental issues but remains controversial. Using a model of inductively justified propositions about awareness, this paper shows how the precautionary principle may be interpreted as a heuristic...

Portable sawmilling trials with Acacia aneura (mulga) and A. cambagei (gidgee) have been undertaken to estimate the private landholder costs associated with small-scale timber production from woodlands in western Queensland, Australia. A time study of harvesting and milling operations...

Farmers are well known to be risk-averse. Although a considerable literature has focused on the role water markets play to allocate water more efficiently, none has explicitly studied the risk management role water markets play in irrigators’ decision making. We used a two-step empirical...

Introducing a stocking rate restriction is one possible course of action for regulators to improve water quality where it is affected by nitrate pollution. To determine the impact of a stocking rate restriction on a range of New Zealand dairy farms, a whole-farm model was optimised with and...

We explore the relationship between the choice of the strategy space and outcomes in Tullock contests. In particular, in a framework where one of the contest's participants moves first, we show that there is an equilibrium where this individual wins the contest with probability one. We also show...

Ecological, evolutionary and economic issues involved in introducing genetically modified organisms (GMOs), mainly in agriculture, are discussed. The ecological and evolutionary impacts identified hamper (economic) valuation of GMOs and their biosafety regulation and creates difficulties for...

In the Millennium Ecosystem Assessment (2005), ecologists identified and pointed out a multitude of environmental and other benefits obtained by human-beings from ecosystem services. Frequently, these benefits are not fully recognized and they are not adequately taken into account in...
