Potential for change in the mix of irrigated enterprises was estimated for a catchment in the Shepparton irrigation region using linear programming. The model allocated resources to maximise net income in each of the next five decades as if the catchment were one farm. Change was driven by price...

Dry land salinisation is a significant cause of land and water degradation in Australia. Changing land use from annual to perennial crops has been widely proposed as a means to reduce land degradation and increase the productivity of saline land. However, in many areas annual crops are...

Several trials have recently taken place in Australia of sealed bid discriminant price auctions for conservation contracts. The trials encourage landholders to competitively tender for funds to provide conservation actions on private land. In these auctions, environmental benefits of offers are...

Indonesia has set the target that by the year 2020 its emissions of greenhouse gases will be reduced by 26 per cent relative to business-as-usual conditions. This paper analyzes the effectiveness of a subsidy to the use of land in forestry as a means of achieving this goal. The analysis uses a...

The spatial pattern of landscape reconstruction makes a substantial difference to environmental outcomes. We develop a spatially explicit bio-economic model that optimises the reconstruction of a heavily cleared landscape through revegetation. The model determines the spatial priorities for...

Much of Australia’s native vegetation has been cleared or altered as a result of agricultural development. The native vegetation that remains on private land is highly fragmented and continues to be degraded and modified due to various land use and environmental pressures. One of the major...

The coastal village of Kampong Kuantan in the state of Selangor, Malaysia is noted for its fireflies (pteropyx tener). The fireflies which flashes every non-rainy night is one of the world's most spectacular insect shows. The local operators formulated strict but informal rules to ensure the...

The chromosol soils of the Duri district range from highly to moderately degraded. The poorer condition results in high overland flow, reduced plant available water, and can lead to greater recharging of lower lying vertosol soils, which have a greater salt store and as a consequence of recharge...
