General circulation models predict significant and accelerating changes in local patterns of precipitation and temperature over the next century. The vulnerability of agriculture to climate change will depend on both the biophysical impacts of climate change on crop yields and on the...

Nitrogen is an important agricultural input that is critical for crop production. However, the introduction of large amounts of nitrogen into the environment has a number of undesirable impacts on water, terrestrial, and atmospheric resources. This report explores the use of nitrogen in U.S....

U.S. farmers and ranchers produce a wide variety of commodities for food, fuel, and fiber in response to market signals. Farms also contain significant amounts of natural resources that can provide a host of environmental services, including cleaner air and water, flood control, and improved...

USDA has spent more than $4.2 billion on wetland restoration and protection over the last two decades. One challenge in allocating these funds is the lack of information on variations in wetland benefits and costs across the Nation. This report discusses the biophysical impacts of new wetlands...

Biogas recovery systems that use methane from manure to generate electricity have not been widely adopted in U.S. mainly because the costs of constructing and maintaining these systems have exceeded the value of the benefits provided. Climate change mitigation and renewable energy policies could...

We present a model that extends the replacement cost theory to cases where benefits are restored for multiple years. Our theoretical framework derives a functional relationship between investments expenditures and environmental benefits. By extending the investment framework, we model reservoir...

Pheasant hunting benefits of the Conservation Reserve Program (CRP) were approximately $80 million/year in 1991 in states where the CRP appears most critical to pheasant populations. To obtain this benefit measure, tire demand for pheasant hunting was estimated using a recently developed...
