The production performance of wheatbelt farms in Western Australia is analysed to determine whether potential to exploit scale economies and improve technical efficiency has driven the trend towards increased farm size. An input-orientated stochastic frontier model is used to estimate technical...

Shrimp culture areas and production of the Mekong Delta cover about 60 percent of the total shrimp areas and production of Vietnam. Especially, the Delta contributes about 80 percent of the total shrimp production for export. Rapid development of the shrimp industry is raising a number of...

Inclining block tariffs, where the unit price is dependent on the volume consumed, are widely used in urban water pricing. These tariffs attempt to satisfy both efficiency and equity goals by providing pricing signals to influence consumption decisions at the margin, whilst making...

The environmental consequences of shrimp farming in Asia have caused widespread public concern. One of the main environmental impacts is the high nutrient load that is discharged from ponds, as part of the management routine aimed at maintaining pond water quality. In Australia, where there is a...

The regulation of river systems to meet water demands for irrigation in the southern Murray Darling Basin has changed the timing and the volume of the natural pattern of flows. Australian governments have committed to restoring, in part, winter and spring flow regimes to preserve and enhance the...

Government and non-government conservation agencies have long-term goals and objectives to provide environmental services, such as conserving the biodiversity of Australian native vegetation. In addition to national parks and reserves, private lands are often included in conservation programs to...

This paper explores the economics of land degradation in the rice-shrimp system in the Mekong Delta of Vietnam. A bioeconomic NPV model was developed to evaluate and compare the long-term benefits of alternative production choices and farm technologies. There is an alternative rice-shrimp...
