| This paper develops a dynamic, regional analysis of the effects of US and European biofuel mandates on land use, forestry stocks, and carbon emissions. The results suggest that these mandates may cause an additional 23-26 million hectares of forestland losses globally, but additional carbon emissions of 1.2 – 1.6 billion t CO2. The estimates are found to be sensitive to the elasticity parameter on the land supply function in the model, with the higher elasticity estimates associated with larger carbon losses. The regional analysis turns out to be quite important, because some regions end up gaining forestland and increasing carbon stocks. The regional and dynamic effects have been missed by most other noteworthy analyses of the induced land use effects... |

| This study develops a model of land use change in the Midwestern States of Ohio, Indiana, and Illinois. Given the emergence of spatial econometrics, three models are compared to assess the sensitivity of the estimates to alternative assumptions about the distribution of their errors. Projections of future land use change are then developed, and the results are compared across different assumptions about population growth and models. We then estimate carbon sequestration potential in the region and compare the costs of different programs across the population assumptions and the alternative models. Different assumptions about population growth and error terms do not appear to affect the carbon sequestration cost estimates. |

| There is widespread concern among environmental and agricultural interest that land use change will affect the future productivity of the agricultural industry by utilizing highly productive land for development. This paper considers the links between land use change and crop choices in order to analyze whether land use change is influencing crop choices. In order to account for potential endogeneity between crop choices and land use choices, we develop a Markov Model that allows us to capture potential endogeneity between these two choices (land use and crop choice). The Markov model is developed for the 12 Midwestern U.S. States using USDA NRI data at the county level. |

| This study takes advantages of recent developments in measuring total factor productivity in output specific directions to examine the influence of technological change in different agricultural sectors on land-use decisions in a cross-section of countries from 1969 to 2001. Results demonstrate a positive relationship between productivity and land in agriculture in most cases. The ruminant sector is an exception where an increase in productivity was negatively associated with amount of pastureland. The analysis also includes variables that have been found to be important determinants in other studies of land-use change. Population is clearly the dominant factor over the time period analyzed, although it is argued that other factors are likely to become... |

| Forestry has been considered to have potential in reducing the atmospheric concentration of carbon dioxide by sequestrating carbon in above-ground timber and below-ground roots and soil. This potential has been noted in the Kyoto Protocol, which identified specific forestry activities for which carbon sequestration credits could be obtained. To date, a few forestry efforts have been undertaken for carbon purposes, but most of these efforts have been on a small scale. Proposals have been under discussion, however, that would result in the creation of very large areas of new forest for the purpose of offsetting some of the additional carbon that is being released into the atmosphere. Concerns are expressed, however, that large-scale sequestration operations... |

| This paper investigates the potential contribution of forestry management in meeting a CO2 stabilization policy of 550 ppmv by 2100. In order to assess the optimal response of the carbon market to forest sequestration we couple two global models. An energy-economy-climate model for the study of climate policies is linked with a detailed forestry model through an iterative procedure to provide the optimal abatement strategy. Results show that forestry is a determinant abatement option and could lead to significantly lower policy costs if included. Linking forestry management to the carbon market has the potential to delay the policy burden, and is expected to reduce the price of carbon of 40% by 2050. Biological sequestration will mostly come from avoided... |

| There is widespread recognition that forestry carbon credits can reduce the net emissions of carbon into the atmosphere. Designing systems to sequester carbon, however, has proven difficult due to a number of efficiency issues, including leakage. Leakage occurs when policy makers develop carbon projects in specific places which protect some parcels of land, but leave other parcels of land unprotected. This analysis uses a newly developed model of global land use change from an established forestry and land use model, described in Sohngen et al. (1999); Sohngen and Mendelsohn (2003); and Kindermann et al. (2008). To assess leakage we estimate carbon under storage under one scenario where the world is awarded carbon credits and another where tropical... |

| This study develops cumulative carbon 'supply curves' for global forests utilizing an dynamic timber supply model for sequestration of forest carbon. Because the period of concern is the next century, and particular time points within that century, the curves are not traditional Marshallian supply curves or steady-state supply curves. Rather, the focus is on cumulative carbon cost curves (quasi-supply curves) at various points in time over the next 100 years. The research estimates a number of long-term, cumulative, carbon quasi-supply curves under different price scenarios and for different time periods. The curves trace out the relationship between an intertemporal price path for carbon, as given by carbon shadow prices, and the cumulative carbon... |

| The goal of this work is to investigate land-use change at the global scale over the long run particularly in the context of analyzing the fundamental drivers behind land-use related GHG emissions. For this purpose, we identify the most important drivers of supply and demand for land. On the demand side, we begin with a dynamic general equilibrium (GE) model that predicts economic growth in each region of the world, based on exogenous projections of population, skilled and unskilled labor and technical change. Economy-wide growth is, in turn, translated into consumer demand for specific products using an econometrically estimated, international cross-section, demand system that permits us to predict the pattern of future consumer demands across the... |

| The rapid change in the character of land use in traditional agricultural regions of the Midwest has led to public concern in recent years. As a result, policy makers have attempted to forge novel ways to cope with problems associated with loss of farmland and the encroachment of urban/suburban sprawl. Some of the policies that have been implemented or suggested in a number of jurisdictions include purchase of development right programs, impact fees, agricultural zoning, and preferred tax treatment for agricultural land uses, among others. In this paper, we explore the forces that promote land use change in order to help public officials make informed decisions on policy implementation. |

| Pollution from nonpoint sources (NPS), and agriculture in particular, remains as one of the largest sources of water quality impairments in the United States. As is well known in the literature, there are many difficulties with designing regulations for reducing nonpoint source pollution (i.e., Tomasi, Segerson, and Braden, 1994). Uncertainty and asymmetric information are the key regulatory difficulties in the control of NPS. The main goal of this paper is to describe a potential incentive scheme that can be applied in limited information situations. The incentive scheme involves a contract written between a point source of pollution and a small group of other nonpoint polluters in the watershed to reduce a specific load of pollution. The contract allows... |
