| The present article uses the modified Arkansas off-stream reservoir analysis and the environmental policy-integrated climate models to examine the impacts of on-farm reservoirs and tail water recovery systems in conjunction with other best management practices on profitability, water use, and sediment control for rice-soybean farming operations. Results suggest that, under limited water availability conditions, reservoirs and tail water recovery systems can improve profitability, reduce ground water dependence, and reduce the movement of sediment, nutrients, and pesticides off-farm. Although reservoirs may not be profitable under plentiful water conditions, cost-sharing opportunities may make them a viable means of addressing environmental concerns. |

| A number of programs have been introduced to limit environmental nonpoint pollution (NPP) associated with agricultural practices. One such program, precision agriculture, involves a range of management practices that utilize site-specific information at the field level. These practices can limit the amount of nutrient and chemical runoff to the environment because they precisely match fertilizer and pesticide application to the needs of the crop. This study uses bioeconomic modeling to investigate the environmental and economic impacts of precision agriculture technology associated with variable rate fertilizer application, as compared to a conventional, single rate application. The empirical results demonstrate that one particular precision... |

| To meet environmental target, policies that coordinate nonpoint pollution control efforts within a watershed may result in higher total profits than policies that do not. That is, the greatest profits and most runoff reduction would be achieved with optimal combinations of BMPs. However, the uncertainty weather condition could pose some challenge in achieving environmental target. In this study, we use a bioeconomic model, Agricultural Policy Envi-ronment Extender (APEX) to simulate the environmental impacts of alternative cropping sys-tems. Under safety-first constraints, the levels of environmental runoff and optimal net returns of alternative cropping practices are estimated, using GAMS. |

| A contingent valuation survey conducted in Mississippi is used to assess public willingness to pay for reductions in agricultural nonpoint pollution. The analysis focuses on implementation of a policy to provide farmers with precision application equipment to reduce nutrient runoff. Findings suggest public support exists for such policies. This study also finds that inclusion of debriefing questions can be used to refine willingness-to-pay estimates in contingent valuation studies. A nonparametric scope test suggests respondents are sensitive to level of runoff reduction and associated water-quality benefits. |
