| Fertile land and fresh water constitute two of the most fundamental resources for food production. These resources are affected by environmental, political, economic, and technical developments. Regional impacts may transmit to the world through increased trade. With a global forest and agricultural sector model, we quantify the impacts of increased demand for food due to population growth and economic development on potential land and water use. In particular, we investigate producer adaptation regarding crop and irrigation choice, agricultural market adjustments, and changes in the values of land and water. |

| As Congress develops new farm legislation, some are lobbying for a new partnership between U.S. taxpayers and farmers. In exchange for an annual transfer of $10 to $20 billion from taxpayers to agriculture, farmers would do much more to enhance environmental quality. An attractive feature of a new partnership is that paying for an improved environment provides a clear and justifiable rationale for farm program payments, something that is lacking under current farm programs. By changing management practices and land use, farmers can provide cleaner water, cleaner air, better wildlife habitat, lower net greenhouse gas emissions, and improved long-run soil quality. Private profit maximizers largely ignore the value of these environmental goods. Hence, the... |

| We use the Agricultural Sector Model to analyze the economic potential of soil carbon sequestration as one of several agricultural greenhouse gas emission mitigation strategies, including afforestation. For low incentives on carbon emission savings, agricultural soil carbon sequestration is the most cost-efficient strategy. As incentive levels increase above $50 per ton of carbon equivalent, afforestation and biofuel production become the key strategies, while the role of soil carbon diminishes. If saturating sinks are discounted based on their net present value, the competitive economic equilibrium among agricultural mitigation strategies shifts away from soil carbon sequestration and afforestation and toward more biofuel production. Regardless of the... |

| The Kyoto Protocol represents the first international agreement to reduce greenhouse gas emissions. Proposed mitigation efforts may involve the agricultural sector through such options as planting trees, crop and livestock management changes, and biofuels production. The combined use of these strategies could substantially reduce net emissions of carbon dioxide, methane, and nitrous oxide. However, countries where the Protocol imposes emissions caps have expressed concern about their competitiveness with countries that are not part of the Kyoto Protocol. In a free-trade arena, food production and exports in unregulated countries could increase and reduce market share for the producers in complying countries. We examine the effects of differential Protocol... |

| Policies to mitigate greenhouse gas emissions are likely to increase energy prices. Higher energy prices raise farmer costs for diesel and other fuels, irrigation water, farm chemicals, and grain drying. Simultaneously, renewable energy options become more attractive to agricultural producers. We consider both of these impacts, estimating the economic and environmental consequences of higher energy prices on U.S. agriculture. To do this we employ a price-endogenous agricultural sector model and solve that model for a range of carbon-tax-based energy price changes. Our results show mostly positive impacts on net farm income in the intermediate run. Through market price adjustments, fossil fuel costs are largely passed on to consumers. Additional farm... |

| Livestock is recognized as one of the major drivers of current and future global change. This is caused on the production side, by the substantial resource requirements (land and water) per unit of output, and the related greenhouse gas emissions, and on the consumption side, by the growing demand due to population and economic growth. Our paper investigates whether productivity gains which enabled to the crop sector to satisfy the increased demand under decreasing real prices, and with little additional land, in the past decades, can be expected in the livestock sector in the future. To answer this question, we implement the recursively dynamic partial equilibrium bottom-up model of the global agriculture and forest sectors (GLOBIOM), expanded by a newly... |

| Economic impacts of agricultural carbon sequestration involve direct costs ofsequestration management adoption as well as a variety of indirect costs and benefits. The nature and significance of these impacts are discussed. Spatial and temporal heterogeneity in agriculture is identified as an influential factor. Techniques to estimate the cost of agricultural carbon sequestration are briefly reviewed and compared. Mathematically programming is used to simulate carbon sequestration in the U.S. agricultural sector and to provide experimental evidence of the existence and magnitude of economic impacts. |

| Mathematical programming is used to examine the economic potential of greenhouse gas mitigation strategies in U.S. agriculture and forestry. Mitigation practices are entered into a spatially differentiated sector model and are jointly assessed with conventional agricultural production. Competition among practices is examined under a wide range of hypothetical carbon prices. Simulation results demonstrate a changing portfolio of mitigation strategies across carbon prices. For lower prices, preferred strategies involve soil and livestock options; higher prices, however, promote mainly afforestation and biofuel generation. Results demonstrate the sensitivity of individual strategy potentials to assumptions about alternative opportunities. Assessed impacts... |
