The CLUES model is an integrated catchment based model that designed to assist policy makers in understanding the implications of land use scenarios for water quality and a range of other indicators. CLUES integrates a number of existing models from several research providers, including SPARROW...

This paper presents an irrigation farm management tool, SALMOD (Salinity And Leaching Model for Optimal irrigation Development), that calculates the profit maximizing crop enterprise composition and irrigation management options for farm specific soil type, drainage status and irrigation system...

A model of land allocation at the aggregate watershed level was developed assuming profit/net benefit maximization under risk neutrality. The econometric land use model was analyzed as an equation by equation SURE model as all the independent variables were the same for both equations. In...

In 2010, a Total Maximum Daily Load (TMDL) was established for the Chesapeake Bay, defining the limits on emissions of nitrogen, phosphorus, and sediment necessary to reverse declines in the Bay’s quality and associated biological resources. Agriculture is the largest single source of...

The design of competitive tenders to purchase environmental services requires judgements to be made about the funding scale and tender scope, with the latter incorporating considerations of geographic area, industries involved and the types of environmental outputs required. Increasing the scale...

We examine how much on-farm reservoirs can increase groundwater quantity and improve surface water quality using a spatial-dynamic model of farm profit maximization in the Arkansas Delta. Sensitivity analysis of the farm profit objective by including the value of surface water quality and the...

We investigate effects of corn-based ethanol plants on local land uses using county-level panel data for Iowa for 1997 through 2009 and an Arellano-Bond difference-generalized method-of-moments estimator. Our results show that ethanol plants have statistically significant effects on the...

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...

Beneficial management practices (BMPs) are designed to minimize environmental impacts and provide on- and off-farm benefits such as improved farm economics and enhanced water quality for domestic consumption, recreation and healthier aquatic ecosystems. Adoption of BMPs depends on the...

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...
