We develop a catchment scale modeling framework to identify cost-effective strategies for joint onsite abatement and offsite mitigation of land-based pollution from agricultural activities that pose a risk to water quality in the Great Barrier Reef (GBR). An illustrative example of the Barron...

With increasing signs of climate change and the influence of national and international carbon-related laws and agreements, governments all over the world are grappling with how to rapidly transition to low-carbon living. This includes adapting to the impacts of climate change that are very...

Lake Hume is a significant water storage located at the headwaters of the River Murray. It provides irrigation water, urban water supplies, flood mitigation and recreational benefits to a large and economically significant region. Water quality in Lake Hume has recently been the subject of...

Agricultural and forestry GHG emissions are a key feature of New Zealand’s emissions profile, and New Zealand is the only country, to date, to have indicated that agricultural and forestry emissions will be covered under their domestic climate policy – the New Zealand Emissions Trading...

Estimates of environmental values are frequently required as inputs to cost-benefit analyses when evaluating alternative resource use options. One strategy to avoid the high cost of conducting empirical work when non-market values are involved is to use value estimates from an existing study and...

made in one situation to related circumstances. The benefit transfer process is typically reliant on the availability of a number of source studies which have appropriate levels of reliability and relevance to the issue of interest. However, the limited number of non-market valuation studies to...

This paper uses responses from a regional farmer survey that identify farmers’ perceptions of environmental policies to calibrate a catchment-level environmental economic model (NZ-FARM) to estimate the impacts of a nutrient reduction policy in North Canterbury, New Zealand. The model...

Despite the importance of the agricultural and downstream processing sectors in the New Zealand economy, there is no tradition of using partial or general equilibrium models to evaluate policies or other measures directed at the agricultural sector. Policy-makers have instead relied on the...

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...
