Sustainability is the paradigm of our time, yet its use as a guide to planning or decision making is clouded by its ambiguity and the multiplicity of definitions in use. In this paper we address the issue of how best to deal with the multi-faceted nature of sustainability. We outline each of the...

Groundwater extraction can have varied and diffuse effects. Negative external effects may include costs imposed on other groundwater users and on surrounding ecosystems. Environmental damages are commonly not reflected in market transactions. Groundwater transfers have the potential to cause...

Perth, Western Australia (pop. 1.6m) derives 60% of its public water supply from the Gnangara groundwater system (GGS). Horticulture, domestic self-supply, and municipal parks are other major consumers of GGS groundwater. The system supports important wetlands and groundwater-dependent...

Many economists are concerned with communicating the results of economic analysis or the implications of economic theory to policy makers. Our effectiveness in doing this varies widely for different individuals and different issues. The present paper is an attempt to provide practical advice to...

The development of a market in groundwater usage rights can be inhibited by constraints arising from the institutional context. Such impediments may reduce the potential gains from trade and may generate high transaction costs for prospective traders. We analyse the regulations and policies...

Dryland salinity, as an externality, has an impact on various public assets, including roads, biodiversity and public water supplies. This has been seen as an important justification for government to take action and internalise the pollution. Economic policy instruments have been identified as...

This paper describes a complex, dynamic simulation model that has been developed for the analysis of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli) in rice farming systems in the Philippines. Users of the model may simulate any feasible...

This is a broad-ranging discussion of the role of economics and economists in the formation of government policies. The focus is on helping economists who wish to be influential in the policy process. The paper covers rationales for and against economist involvement in the policy process (market...
