The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) is responsible for controlling
grasshopper populations on public rangelands. Under current guidelines, control of grasshoppers on rangeland should occur if
grasshopper densities are at least eight per square yard. This article evaluates the concept of an economic threshold relative to the
value of forage saved from destruction during a grasshopper outbreak. It is shown that financial justification for treating
grasshopper outbreaks depends upon grasshopper density, rangeland productivity, climate factors, livestock cost and return
relationships, and the efficacy of treatment options.

This study explores the interactions of groundwater extraction, quality, and greenhouse-gas (GHG) emissions within a productive
agricultural region. Two conceptual models are proposed. In the first, GHG emissions are managed at the local level, and an
efficient level of abatement is solved for endogenously to the system. Here, regional management of GHG emissions offers an
alternative policy tool for managing quantity/quality by internalizing the costs of a common externality associated with both
groundwater extraction and nitrogen fertilizer application. A simple numerical simulation is used to illustrate the potential
groundwater co-benefits of managing agricultural GHG emissions within the system. The second model reflects the reality that
