Assessing the Uncertainty of Land Based Carbon Sequestration: A Parameter Uncertainty Analysis with a Global Land Use Model
Provedor de dados: 31
Autores: Kim,   Yoon Hyung; Sohngen,   Brent.
This paper analyzes the effect of uncertainty in several key parameters on the marginal costs of carbon sequestration in forests. These parameters include the land supply elasticity, which governs the conversion of land from agriculture to forests and vice versa; parameters of the forest biomass yield function; parameters of the forest carbon density function; and parameters of the costs functions for accessing inaccessible land. Monte Carlo techniques are thus used to turn the global forest model with no probability (e.g., Sohngen &amp; Mendelsohn, 2003; 2007) into a proper probability model through Latin hypercube sampling.       For this paper, we have restricted our analysis to consideration of probability distributions for only two of the parameters...

Biofuel Growth: Global Greenhouse Gas Emissions Impacts from Changes in Forest Carbon Stocks
Provedor de dados: 31
Autores: Golub,   Alla A.; Hertel,   Thomas W.; Rose,   Steven K.; Sohngen,   Brent.
There is significant policy interest in liquid biofuels with appealing prospects for energy security, farm security, poverty alleviation, and climate change. Large-scale commercial biofuel production could have far reaching implications for regional and global markets – particularly those related to energy and land use. As such, large-scale biofuels growth is likely to have significant impacts on global greenhouse gas (GHG) emissions. This paper utilizes a CGE model with explicit biofuel, land, and energy markets. The model is able to estimate the effects on the broad range of input and output markets potentially affected globally by biofuels policies. One of the most controversial issues within the biofuels debate is potential indirect changes in land use...

Economics of Forest Ecosystem Carbon Sinks: A Review
Provedor de dados: 31
Autores: van Kooten,   G. Cornelis; Sohngen,   Brent.
Carbon terrestrial sinks are seen as a low-cost alternative to fuel switching and reduced fossil fuel use for lowering atmospheric CO2. In this study, we review issues related to the use of terrestrial forestry activities to create CO2 offset credits. To gain a deeper understanding of the confusing empirical studies of forest projects to create carbon credits under Kyoto, we employ meta-regression analysis to analyze conditions under which forest activities generate CO2-emission reduction offsets at competitive ‘prices’. In particular, we examine 68 studies of the costs of creating carbon offsets using forestry. Baseline estimates of costs of sequestering carbon are some US$3–$280 per tCO2, indicating that the costs of creating CO2-emission offset credits...

A GLOBAL MODEL OF CLIMATE CHANGE IMPACTS ON TIMBER MARKETS
Provedor de dados: 31
Autores: Sohngen,   Brent; Mendelsohn,   Robert; Sedjo,   Roger A.
Several papers have now estimated the impact of climate change on national timber markets, but few studies have measured impacts globally.  Further, the literature on impacts has focused heavily on changes in productivity and has not integrated movements of biomes as well.  Here, a dynamic model of ecological change and economic change is developed to capture the impact of climate change on world timber markets.  Climate change is predicted to increase global timber production as producers in low-mid latitude forests react quickly with more productive short-rotation plantations, driving down timber prices.  Producers in mid-high latitude forests, in contrast, are likely to be hurt by the lower prices, dieback, and slower productivity increases because of...

We use the contingent valuation method to estimate participant willingness to pay for agricultural economics extension programming.  The data, collected as part of standard evaluation forms for the Ohio State University's 2001 Agricultural Outlook and Policy program series, and subsequent analysis suggest participant benefits exceeded departmental costs of conducting the program (benefit-cost ratios of 1.07 under conservative assumptions and 1.74 under moderate assumptions).  We also use the data to explore the revenue generation potential from alternative program pricing and discuss the potential for developing differentiated programs to reach distinct audience segments.  Additional research necessary before implementing alternative pricing or program...

An Analysis of Global Timber Markets
Provedor de dados: 31
Autores: Sohngen,   Brent; Mendelsohn,   Robert; Sedjo,   Roger A.; Lyon,   Kenneth S.
This paper presents a model of global timber markets that captures the evolution of a broad array of forest resources and timber market margins over time. These margins include the inaccessible northern and tropical margins, plantation establishment, and timberland management. A baseline case is presented and discussed. Five alternative scenarios are then presented. These scenarios allow us to consider several important questions about timber market behavior and the future supply of industrial fiber: (1) What happens along the northern and the tropical inaccessible margins? (2) What role do timber plantations play? and (3) How do shifts in management intensity interact with market forces? The baseline case suggests that both prices and harvests rise over...

Exchange Rates and the Competitiveness of the US Timber Sector in a Global Economy
Provedor de dados: 31
Autores: Daigneault,   Adam J.; Sohngen,   Brent; Sedjo,   Roger A.
This paper examines the competitiveness of the US timber industry under different exchange rate policies using a dynamic optimization model of global timber markets.  We assume that exchange rates affect the cost structure of harvesting and managing forests and simulate the model for baseline conditions and four additional exchange rate policies.  Two policies consider a strengthening United States dollar scenario and two policies examine weak South American currencies.  Recently South America has increased its share of global timber production and is shipping increasing quantities of timber to the Unites States.  The results indicate that US competitiveness in the forestry sector is sensitive both to strong US $ policies and to the weak currency policies...

EFFECTS OF LOCAL DEVELOPMENT PRESSURE ON LAND PRICES: A SPATIAL ECONOMIC APPROACH
Provedor de dados: 31
Autores: Jeanty,   Pierre Wilner; Kraybill,   David S.; Libby,   Lawrence W.; Sohngen,   Brent.
We conduct a study to examine the effects of local development pressure and other factors on the value of urban-fringe land parcels. Multiple regression spatial models were estimated using parcel- level data from Delaware County, Ohio. The empirical results provide evidence that such factors as man-made and natural features are relevant in determining property values. The econometric findings indicate that local development pressure contributes profoundly to an increase in current land prices. These results shed light on the magnitude of the effects of recently developed land and provide insights into policies to preserve farmland and the associated environmental benefits.

Global interactions between bioenergy and climate policies
Provedor de dados: 31
Autores: Golub,   Alla A.; Hertel,   Thomas W.; Rose,   Steven K.; Sohngen,   Brent.
Over the past few years, interest in bioenergy has boomed with higher oil prices and concerns about energy security, farm incomes, and mitigation of climate change. In the same time, there is significant interest in international agricultural and forestry based greenhouse gas (GHG) mitigation.  However, bioenergy and climate policies are being formulated largely independent of one another. Understanding the interaction between these potentially competing policy objectives is valuable for identifying possible constraints that one policy might be placing on the other, as well as potential complementarities. Using a general equilibrium framework, this study assesses the effects of bioenergy expansion on sectoral, regional and global GHG emissions mitigation...

THE OPTIMAL CHOICE OF RESIDUE MANAGEMENT, CROP ROTATIONS, AND THE COST OF SOIL CARBON SEQUESTRATION
Provedor de dados: 31
Autores: Choi,   Suk-Won; Sohngen,   Brent.
This paper develops a dynamic model of land, crop, and residue management choices in a typical Midwestern farm region. Carbon renting policy is implemented with alternative assumptions about relative crop prices. Model results show following results. First, crop choice between corn and soybean within a scenario does not appear to be sensitive to carbon prices. Second, residue management and carbon storage depend on crop prices and total carbon storage in soil is the greatest when more land is maintained in soybean. Third, there would be 4-7% increase in carbon per hectare with $3 per ton carbon price, 13-23% increase with $10 per ton carbon price, and 31-55% increase in carbon storage with $40 per ton carbon price.

Zoning, Development Timing, and Agricultural Land Use at the Suburban Fringe: A Competing Risks Approach
Provedor de dados: 31
Autores: Hite,   Diane; Sohngen,   Brent; Templeton,   Josh.
Competing risks survival analysis is used to investigate tax and zoning policy impacts on residential, commercial, and industrial development timing in a rapidly growing Midwestern county. Industrial development appears both to precede and occur concurrently with residential development, while commercial development follows other types. Although residences appear to locate away from industrial land, zoning decisions favoring industry may attract rather than deter residential development within a jurisdiction. Regions with higher infrastructure taxes experience development later. Because school taxes fund local public goods important to homeowners, they have little influence on residential timing, but strong influences on industrial and commercial timing.

LAND USE CHANGE AND PROPERTY TAXES: AN EMPIRICAL STUDY OF THE EFFECT OF PROPERTY TAXES ON THE TIMING OF LAND CONVERSION FROM AGRICULTURAL TO RESIDENTIAL DEVELOPMENT
Provedor de dados: 31
Autores: Sohngen,   Brent; Hite,   Diane; Templeton,   Josh.
This study explores how property taxes affect the timing of development.  The theoretical literature suggests that higher taxes increase the time to development, although there is some disagreement in the literature. We present a simple theoretical model to motivate an empirical model that explores how land use change decisions are made over time.  A hazard model is used to predict factors that influence the time to development over an 11-year period in an urbanizing county in the Midwestern corn belt.  The results suggest that higher taxes slow development, as expected.  Over the 11-year period for our sample, we predict that 25% more agricultural land would have converted to development if taxes had not risen.  We also find, however, that the effects are...

A Comparison of Timber Models for Use in Public Policy Analysis
Provedor de dados: 31
Autores: Sohngen,   Brent; Sedjo,   Roger A.
In this paper, we compare and contrast two types of timber models that have been used for public policy analysis. These models have been variously used to predict price, inventory and market welfare impacts under different exogenous forces that impact timber markets. The framework and theory for each model type is presented and discussed. We then thoroughly test the two model types across six potential exogenous shocks to timber markets, ranging from instantaneous demand shocks to gradual supply adjustments. Our comparison indicates that these models predict potentially important differences in timber market behavior. These differences are important to consider for those who do public policy analysis.

IMPACT OF US AND EUROPEAN BIOFUEL POLICIES ON FOREST CARBON
Provedor de dados: 31
Autores: Kim,   Yoon Hyung; Sohngen,   Brent; Golub,   Alla A.; Hertel,   Thomas W.; Rose,   Steven K.
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...

LAND-USE CHANGE AND CARBON SEQUESTRATION IN THE FORESTS OF OHIO, INDIANA, AND ILLINOIS: SENSITIVITY TO POPULATION AND MODEL CHOICE
Provedor de dados: 31
Autores: Choi,   Suk-Won; Sohngen,   Brent; Alig,   Ralph J.
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.

Optimal Forest Rotations with Environmental Values and Endogenous Fire Risk

Autores: Daigneault,   Adam J.; Sohngen,   Brent; Miranda,   Mario J.
This paper develops a model that solves for the optimal economic harvest rotation problem to maximize revenue of an even-aged forest plantation when there is a risk of a catastrophic forest fire.  The paper also investigates the feasibility of using fire prone stands for carbon sequestration and estimates the effects that it would have on the optimal management regime and rotation age empirically using a typical Douglas-fir stand in the Pacific Northwest.  The model incorporates risk-reducing management practices that allow risk and growth to be endogenous, and the optimal rotation model is solved using numerical simulation techniques. Results show that higher carbon prices increase the rotation length regardless of the probability of fire and that the...

Assessing the Relationship Between Crop Choice and Land Use Change Using A Markov Model
Provedor de dados: 31
Autores: Hua,   Wei; Sohngen,   Brent; Hite,   Diane.
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 Sequestration of CO2 and Markets for Timber
Provedor de dados: 31
Autores: Sedjo,   Roger A.; Sohngen,   Brent.
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...

Forestry and the Carbon Market Response to Stabilize Climate
Provedor de dados: 31
Autores: Tavoni,   Massimo; Bosetti,   Valentina; Sohngen,   Brent.
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...

How big is leakage from forestry carbon credits? Estimates from a Global Model
Provedor de dados: 31
Autores: Acosta,   Montserrat; Sohngen,   Brent.
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...

COMPETING RISKS IN THE SUBURBANIZATION OF AGRICULTURAL LAND
Provedor de dados: 31
Autores: Hite,   Diane; Sohngen,   Brent; Simpson,   John W.; Templeton,   Josh.
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...
