Land-use change in upper catchments impact downstream water flows. As trees use large amounts of water the expansion of upstream plantations can substantially reduce water availability to downstream users. There can also be impacts on downstream salinity due to reduced dilution flows. In some...

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...

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...

The Australian wheat industry is an important contributor to the Australian economy and farm sector. This paper investigates the determinants of land use in wheat production for the Australian wheat-sheep zone. Land allocation between the wheat and the wool enterprises are considered in view 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...

Over the last decade, following the doi moi reforms, the Vietnamese government has formally recognised the household as the basic unit of production and allocated land use rights to households. Under the 1993 Land Law these rights can be transferred, exchanged, leased, inherited, and mortgaged....

This paper describes an integrated approach developed to model the physical and related social welfare impacts of alternative water allocations in the Dak Lak plateau, Viet Nam. A physically based, distributed and integrated model of the plateau’s surface and groundwater resources has been...

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...

Shortfalls in water supplies are perhaps the greatest practical NRM policy concern in Australia today, looming larger in many minds than the great international debates on greenhouse gasses, climate change and biodiversity. Because forest land cover uses more water than any other, wide expansion...
