Environmental policy evaluation is characterised by a paucity of information. The novel technique of robust mathematical programming is introduced as a means to proactively account for this uncertainty in policy analysis. The procedure allows identification of expected bounds on the range of...

Regional councils throughout New Zealand are in the process of drawing up plans to enable them to meet the requirements of the Resource Management Act and the National Policy Statement on freshwater. Some councils are working on targets for nutrient leaching at the catchment level and are...

Models used for policy evaluation rarely consider firm heterogeneity, despite its importance for instrument design. This study considers agent heterogeneity explicitly in the evaluation of policies for nonpoint pollution control through the integration of decomposition and calibration procedures...

Australian crop and livestock farmers face uncertain climate change and variability and a challenge for adaptation decisions. These decisions can be (1) adjustments to practices and technologies, (2) changes to production systems, or (3) transformation of industries, for example, by relocation...

The possible impacts of projected climate change on Australian agriculture are outlined. The characteristics of climate change that underpin the creation of economic impacts for agriculture are also described and discussed. Climate change is shown to generate spatially and temporally diverse...

Dryland farming is commonplace in Australia so the profitability of dryland farms often depends on the amount and timing of rainfall. With drier weather conditions featuring in climate change projections for southern Australia, it is important to understand the relationships between rainfall,...

The replanting of trees and other high water use perennial plant options has been the major focus of dryland salinity management in recent times. Hydrologists have indicated that unless these options are taken up on a very large scale, little can be done to control ongoing land salinisation in...

Impacts on Australian agriculture of projected climate change are likely to be spatially and temporally diverse, with many regions likely to experience increased downside risk in agricultural production. Some regions, such as south-west Australia, are projected to be particularly at risk of...
