What was accomplished under these goals?
We assessed the crucial role of the farmer by studying the willingness to cultivate feedstock, supply biomass from existing stand, and consider multiple ways of supplying biomass for bioenergy production. Our survey targeted forestland owners with at least 20 acres of forestland and adapted the Tailored Design Method. The survey covered forested counties in South West Alabama, Virginia, and East Texas. Our results suggest that factors such as the manner of land acquisition, acreage, how long respondents have owned the forestland, and forestland ownership objectives, among others, affect forestland owners' decision regarding how much biomass they will leave unharvested. Regarding wood-pellet co-firing programs, we have developed, tested, and conducted surveys to collect consumers' willingness to consider premium payment mechanisms. As part of the survey we developed six attributes including length of the contract, variability of premium such as payments that are either fixed or fluctuating, flexibility of the contract such us opting out with penalty or without a penalty, and location of energy generation as being either in the state or out of the state, and reduction of CO2 emissions varying between 1 to 20 percent. The final attribute was premium payment for the renewable energy certificate for wood pellet, ranging from $10 -$40 per megawatt hour. A total of 2000 consumers from the states of Alabama, New York, New Jersey, Pennsylvania and Virginia responded to the survey we developed. These are states that have a component of co-firing plants as well as bioenergy potential, which were the criteria used for selecting the areas of study. This allows us to make a comparative analysis and develop recommendations that are unique to the relevant states. Our preliminary results indicate that for all the five states the highest wiliness to pay for the overall attribute was for the reduction of CO2, averaging $20.6. The second highest valued attribute was the location of the plant within the state and it's average WTP was $10.84. For flexibility of contract, those with opt-out without penalties, consumers were wiling to pay $9.4 on average. Following this, variability of premium was the next preferred attribute, with the most preferred level being a lower fluctuation of payment, which represents a fluctuation of + 5% in premium, which had an average WTP value of $8. The length of the contract, both levels,12 month and 24 month, had negative WTP values, with 12 level being valued higher. These contract lengths are both stated relative to a six-month contract, which illustrates that people value shorter term contracts. Relatively speaking, the six-month contract is valued by $1.35 higher than the twelve-month contract, which in turn is valued by $3.95 higher than the 24 month contract. These results suggest that consumers are wiling to pay for wood pellet-based co-firing green energy programs and that programs that are shorter in length and with plants that are located within the respective states generate greater support. The same applies to variability. Consumers prefer lower price variability and that reflects in the amount they are willing to pay. The most preferred attribute was the reduction in carbon emission. Policy makers and co-firing plant managers can build on this preference and set of results to reflect consumers preferences. We are currently finalizing the manuscripts that we intend to submit to peer reviewed journals. We are also looking at suitable conferences wherein we can share these findings with other researchers and interested stakeholders.

What opportunities for training and professional development has the project provided?This project has helped in training of three graduate research assistants (Gia Nguyen, Sydney Oluoch and Meghann Smith) and two post-doctoral associates (Bernabas Wolde and Pralhad Burli) How have the results been disseminated to communities of interest?The study results were disseminated through peer-reviewed journal articles, book chapters, and oral presentations at academic conferences. Other community outreach activities included stakeholder meetings with forestland owners, focus group discussion with minority landowners, meeting with contractors/loggers, and a bioenergy webinar at the trade council for technology and technology support companies. What do you plan to do during the next reporting period to accomplish the goals?We will be identifying suitable attributes and their respective levels before determining the willingness consumers have to pay for wood pellet-based bioenergy production programs. We hope that the result we produce will allow conversion facilities to determine not only the strength and reliability of the demand that exists but also help producers gauge the risks and returns from expanding production levels. This will also allow us to address the demand and supply sides of the market. Taken together, the plan of action will allow us to produce results that will improving and sustaining U.S. agriculture and food systems and will be relevant to various stakeholders, including policy makers, scientists, and land managers. The results will also provide critical insights into the levels of woody feedstock expansion in US South and its ensuing impacts on rural communities and minority groups. Thus, our plans include furthering ongoing novel approaches of unique set of data and techniques to provide guidance on agri-environmental program design. They not only extend the project work but also that of the existing literature.

What was accomplished under these goals?
We used data on forestland owners' socioeconomics, forestland features such as acreage, forestland ownership objectives, and forest management activities to determine the factors that affect the regularity of invasive plant removal. The results show that owners with smaller forestlands, and forestland owners without written forest management plans are less likely than others to remove invasive plants species regularly. However, our results also showed that some forest management activities such as building/maintaining roads in the forestland also significantly predict a more regular invasive plant removal tendency, some of which themselves are potential pathways for the spread of invasive plant species. Thus, we show the importance of integrating invasive plant removal plans with forest management plans as well as forestland owners' educational and outreach needs. We applied a computable general equilibrium model to assess the economy-wide impacts of forestland owners' willingness to plant pine on non-forested land for woody bioenergy. The results indicate notable contribution to gross regional product (GDP) ranging from 0.43% to 1.06% and change in equivalent variation social welfare in an amount ranging from $0.215 to $0.46 (USD billions). The changes in gross household income also range from $0.65 to $1.51(USD billions). Overall, our results show an increase in social welfare and household utility. Our results also show the possibility of a marginal decline in GDP and that the increased demand of biomass from logging sector can depress the manufacturing sector in general and the wood manufacturing sub-sector in particular. This interrelationship is noticeable given woody bioenergy's reliance on the logging sector for its intermediate inputs. We believe that the results provide insights into the bioenergy land use competition debate, and pathways towards sustainable bioenergy feedstock supply. We are developing a survey targeting various states both in the South East and North East US. We will use the novel best worst choice (BWC) modeling approach to elicit the data relevant for this study. This approach offers considerable benefits, including such benefits as being the combination of two methods (best worst scaling and discreet choice experiment). This approach also has the advantage of presenting one profile at a time and increasing the statistical efficiency of eliciting preferences. We continueto expand the work we did in exploring frameworks for cellulosic bioenergy market and policy development. Specifically, we explored stakeholder participation, including minority landowners, and validate it using empirical analyses. This research has allowed us to inform policies not only to meet existing needs but also be tailored to different sets of constituents and thereby ensuring a favorable distribution of its benefits to all landowners. Our focus on major pine forest-based regions is also helping us provide the benchmark for determining potential areas with capacity for economic growth in the woody bio-based economy and inform in dollar terms the impact of development of regional woody bioenergy economy.

How have the results been disseminated to communities of interest?The study results were disseminated through publishing peer-reviewed journal article, book chapters, and oral presentations at academic conferences and seminars. Other community outreach activities include stakeholder meetings with forestland owners; Meeting with contractors/loggers; Landowner survey instrument refinementand feedback from university extension professionals engaged in bioenergy research and extension. What do you plan to do during the next reporting period to accomplish the goals? We plan to expand the ongoing work and explore framework for cellulosic bioenergy market and policy development. Specifically, we intend to further explore stakeholder participation, including minority landowners, and validate it using empirical analyses. This work will go beyond the biophysical factors affecting biomass supply. It also delves into socioeconomic conditions and landowner attributes. Thus, it can be used directly to predict landowner response, controlling for demographic and land characteristics. This research will allow us to inform future policies not only to meet existing needs but also be tailored to different sets of constituents and thereby ensure a favorable distribution of its benefits to all landowners. Given the uncertainties that exist, it is important to understand and address negative spatial dis-amenities associated with a potentially increased pine based energy production but also the adoption under uncertainty using stochastic dynamic optimization approach. Thus, it will improve place-based implementation and to evaluate when, where, determine whether it can act as an effective policy instrument, and provide indirect evidence for researchers and policymakers across the U.S. The work on stochastic dynamic optimization analysis will also yield a set of optimal decision rules for loblolly pine plantation under different price paths. Coupling this with the minority forestland owners' involvement in the woody bioenergy market will allow us to estimate the economic impact that will accrue to rural communities and to do at finer scales. Our focus on major pine forest based states in the Southern region will also help us provide the benchmark for determining potential areas with capacity for economic growth in the woody bio-based economy and inform in dollar terms the impact of development of regional woody bioenergy economy. We have developed, tested and are currently running surveys to collect consumers' willingness to consider premium payment mechanisms for wood pellet and biomass based energy, and optimal decision criteria for loblolly pine based bioenergy. this research will allow us to produce results that conversion facilities can use to determine not only the strength and reliability of the demand that exists but also help producers gauge the risks and returns from expanding production levels. This will also allow us to address the demand and supply sides of the market.

Furthermore, we applied a computable general equilibrium model to assess the economy-wide impacts of forestland owners' willingness to plant pine on non-forested land for woody bioenergy. We consider three counterfactual scenarios of biomass feedstock supply increase as intermediate demand for bioenergy production based on forestland owners' willingness to accept biomass bid prices to set aside more non-forested land for biomass production under general equilibrium conditions. Our results show an increase in social welfare and household utility. Our results also show a marginal decline in GDP and that the increased demand of biomass from logging sector can depress the manufacturing sector in general and the wood manufacturing sub-sector in particularly. This interrelationship is noticeable given its reliance on the logging sector for its intermediate inputs. We also report effects on supply price and quantity, sectoral outputs and GDP impacts, as well as household and welfare impacts. These results provide insights into the bioenergy land use competition debate, and pathways towards sustainable bioenergy feedstock supply. Moreover, we assessed the crucial role of the farmer by studying the willingness to cultivatefeedstock and showed that the risk attitudes of farmers have an important bearing on their willingness to cultivate bioenergy feedstock. Having prior awareness, for instance, makes farmers less likely to adopt whereas a preference to cultivate a crop after seeing them on demonstration plots at university extension meetings positively influences willingness decisions. Landholdings under pasture/grazing use and under forest/woodland use increases farmer willingness to cultivate bioenergy feedstock supply such as switchgrass. We also show that having land under the Conservation Reserve Program, lands that experienced flooding or water stress in recent years, or lands that confront erosion issues did not have a significant influence on farmer willingness. This result is important because it shows that policies that provide a safety net to protect farmers from the downside are an important issue for farmers who are willing to cultivate switchgrass.

This result from this research will be important because it will show whether and to what extent policies that provide a safety net to protect farmers from the downside could be relevant issue for farmers who are willing to cultivate switchgrass.
Impacts
What was accomplished under these goals?
As part of the project, we determined forestland owners' willingness to consider multiple ways of supplying biomass simultaneously and identify the factors that predict such behavior, assess overlap in forestland owners across the different ways of supplying biomass, and assess if and how respondents forest management plans and sustainability concerns correspond with their supply decision. Our results suggest that opportunities exist for synergizing programs that incentivize disparate ways of supplying biomass. This finding suggests that the relevant bioenergy incentive programs should also be multi-tiered and adapted to the relevant attributes. Moreover, we studied the proportion of residual biomass forestland owners are willing to leave unharvested for soil nutrient and other environmental benefit purposes, their sustainability concerns, and policy preferences. Our results suggest that factors such as how long respondents have owned the forestland, the way they acquired the forestland, acreage, and forestland ownership objectives, among others, affect decisions regarding how much biomass to leave unharvested. We also found that forestland owners who are likely to engage in harvest practices that do not leave any residual biomass on ground have a preference for policies that help cover management cost and that decision makers administering or considering such policy proposals should be aware of such adverse effects. We also explored forestland owners' heterogeneous preference for various topics onwoody bioenergy and built their profiles for various topics of interest.This result is valuable because forestland owners do not equally prefer all Extension and outreach topics and that affects our ability to effectively deliver information and efficiently allocate limited resources.Thus, we argue for the use of the approach we outlined in objectively ranking audiences' educational interest for different products and services. Additionally, we formulated a discrete-time binomial framework to model output prices, that can incorporate price uncertainty, stand age, and crop yields into the analytical framework. We compute the odds of profit/loss under varying price transition paths for the per ton price of the feedstock and evaluate the relationship between risk and profitability. We also identified investment criteria and estimated the value of flexible decision-making options wherein the farmer can alter cultivation choices. This work is important because uncertainty in future prices coupled with large sunk costs for establishment often inhibits forestland owners' willingness to adopt viable biomass.

What do you plan to do during the next reporting period to accomplish the goals?Currently we are developing new manuscripts based on our analyses and awaiting feedback on submitted manuscripts. We plan to complete the manuscript based on CGE analyses and delineate the economic contributions of cellulosic biofuels in the region. Besides addressing a research need, this will produce a necessary range to allow land owners to better assess the economics of their land use choices. Asmore results are produced from pending analyses, we will shate these at conferences and in peer reviewed journals.
Impacts
What was accomplished under these goals?
We developed woody biofuel expansion scenarios based on future market emergence and socio-economic acceptability considerations. Region-wide socio-economic and distributional impacts were assessed using a Computable General Equilibrium model to identify winners and losers. We also assessed farm and regional impacts of woody biofuel expansion on non-metro (rural) counties in US South, including impacts on persistent poverty and minority dominated counties. The results also included an assessment of forestland owners' preferences for participating in public incentive programs. Considering that enrollment rates are low and that there is limited experience with bioenergy feedstock production, the analyses focused on determining how past experiences and socioeconomic attributes can be used to predict participation in incentive programs. These analyses also included an assessment of how forestland owners evaluate programs that benefit other stakeholders along the supply chain. Results suggest that forestland owners who are less likely to enroll in federal and state sponsored programs have smaller acreage, shorter land ownership tenure, and lower level of education, among others. Moreover, forestland owners with experience in such programs tend to rate future programs, including those that do not directly benefit them directly, more importantly than forestland owners without such experience. These results help us in understanding the attributes of forestland owners that affect likelihood to enroll in such programs, assess how past experience with such programs affect rating of potential programs, target forestland owners less likely to use these opportunities through extension and outreach programs, helping to encourage desired forest management practices and outcomes through federal and state sponsored cost sharing arrangements, tax incentives, and technical assistance programs. While previous approaches mostly focused on understanding the challenges and opportunities facing either foreland owners, loggers and transporters, or processing facilities separately, there is a growing trend at adopting a supply chain approach. As such, instead of focusing, for instance, only on the additional income benefit of woody bioenergy, such development considers how the new revenue for forestland owners or the incentive program available to forestland owners affects the profitable operation of loggers' businesses and the feedstock price paid by processing facilities. Such development might be also better suited at assessing a comprehensive rural development potential of woody bioenergy. Keeping sustainability concerns in mind, the analyses also looked at forestland owners' concerns and opinions regarding the implication of biomass harvest on soil and water quality. By integrating their policy preference with their stated likelihood to harvest residual biomass, this analyses attempts to inform relevant policies of how to encourage biomass supply in a way that minimizes adverse effect on water and soil quality. These studies included clear policy implications of the results and ways forward. This will ensure that relevant findings are passed on to decision makers and that researcher and others alike can build on existing findings. Our analyses suggest need for a localized place-based framework for improved understanding of bioenergy feedstock expansion in the future coupled with bioenergy acceptability and price uncertainty along the bioenergy supply chain. A systematic assessment will benefit policy makers, scientists, and land managers at local, state, regional, and national levels. The decision whether to use a place-based framework any given situation requires an effective learning environment to both improve its implementation and to evaluate when, where, and if it can act as an effective regional development approach. In the context of bioenergy, making a positive connection between bio-economy and local economic growth requires more coherent strategies, suggesting need for a place-based research approach to bioenergy feedstock expansion and conversion plant deployment. We conducted economic analyses to assess if conversion facilities can produce cellulosic ethanol at competitive prices. Towards this end, we assessed the streams of income for a conversion facility from ethanol sales at different prices, capital investment and operating cost analysis to estimate unit cost of producing a gallon of gasoline equivalent cellulosic ethanol. Our preliminary results indicate that cellulosic ethanol can be produced at a competitive price at lower discount rates and prices that are 25 percent higher than the unit cost of producing a gasoline equivalent gallon. Our sensitivity analysis indicates that unit cost of ethanol is significantly influenced by changes in capital return factor and feedstock prices given their proportionally bigger role in the total cost. Such sensitivity of profitability to capital returns factor and feedstock prices may indicate a need for tax credits on capital investments or other forms of assistance to manage risk for conversion facilities. If the conversion efficiency of conversion plants is increased to 95 from 75 percent, the unit cost per gasoline equivalent gallon of ethanol can be brought down by as much as $0.28. By developing scenarios encompassing land suitability, fertilization and raking practices, coupled with average state specific stumpage prices, we also estimated the mean per acre returns using land expectation value (LEV) in three study states. For an assumed rotation age of 33 years, the per acre LEV for loblolly pine in Texas ranges from $279.61 (no fertilization no raking) to $ 636.41 (fertilization and raking taking place two times). The LEV per acre ranged from $238.97 to 815.88 and $333.66 to1088.57 for Virginia and Alabama, respectively. The LEV for slash pine in Alabama was much lower ranging between $260.73 and $940.32. The CGE modeling included analyses of the land use change effect on gross regional product, gross household income, change in government revenue and expenditure, resulting change in social welfare change in social welfare, and change in producer commodity prices. The results indicate notable contribution to gross regional product (GDP) ranging from 0.43% to 1.06%, and change in equivalent variation social welfare in an amount ranging from $0.215 to $0.46 (USD billions). The changes in gross household income also range from $0.65 to $1.51(USD billions).

What opportunities for training and professional development has the project provided?This project has helped in training of three graduate research assistants (Bernabas Wolde, Pralhad Burli and Sushant Singh) and one post-doctoralassociate (Thomas Ochuodho). How have the results been disseminated to communities of interest?The study results were disseminated through publishing peer-reviewed journal article, book chapters, and oral presentations at academic conferences and seminars. Other community outreach activities include stakeholder meetings with forestland owners in states of Texas, Virginia, and Alabama; Meeting with contractors/loggers; Landowner survey instrument refinement and feedback from university extension professionals engaged in bioenergy research and extension. What do you plan to do during the next reporting period to accomplish the goals?Currently we are developing manuscripts and awaiting feedback on submitted manuscripts based on survey. We plan to complete the CGE analyses and delineate the economic contributions of cellulosic biofuels in the region. This will give us the opportunity to better determine the employment and income effects. We are working on delineating the SAM dataset by applying Computable General Equilibrium (CGE) model. This will allow us to better determine the economic impacts associated with the growth of biofuels in the thirteen southern states. The on-going project deals with how changing land use to establish land for feedstock production will interact with other land use and products, including pasture and croplands. Since we have also calibrated and validated the data, the results should produce realistic parameters. We have also included data from the survey. This gives us a unique opportunity to integrate the survey data derived values with the SAM data, allowing us a unique perspective that other studies do not always have. This will also help us determine a more accurate estimation as the inputs to subsequent analyses are not based on random set of assumptions but derived from actual forestland owners' preferences.
Impacts
What was accomplished under these goals?
As part of the project, we conducted a techno-economic profitability analyses. This study involved assessing the unit cost of producing cellulosic ethanol and included state specific data from three southern states, two conversion efficiency levels, and sensitivity analyses. Our results detail the economic conditions required for a profitable cellulosic ethanol production and the potential role policy makers can play in ensuring that outcome. This analysis was coupled with farm-gate analyses, attempting to determine net present values associated with growing pine for bioenergy production. This helps us understand and inform interested land owners about the economics of a pine plantation. To ensure relevance, we included different scenarios including raking, fertilization, land preparation, thinning, and varying discount rates. This aspect of the study also details under what type of economic conditions land owners will generate the highest per-acre revenue. The fact that we accounted for these different scenarios will contribute towards making the result relevant to land owners under varying circumstances and ensure an estimation of results with a corresponding range and margins of error. We have also included costs and co-products for a more accurate measurement of the economics involved in producing cellulosic ethanol. As such, data included in this analyses ranges from feedstock purchase, conversion as well as its delivery. Quantitative and qualitative primary data was collected through the use of survey instrument based on randomly selected private forestland owners from each state. Our survey targeted forestland owners with at least 20 acres of forestland and adapted the Tailored Design Method. The survey covered forested counties in South West Alabama, Virginia, and East Texas. Our results suggest that factors such the manner of land acquisition, acreage, how long respondents have owned the forestland, and forestland ownership objectives, among others, affect forestland owners' decision regarding how much biomass they will leave unharvested. Moreover, analyses of their sustainability concerns indicate a clustering pattern, concerns about sufficiency of best management practices and the potential implications of their harvest decision on soil and water quality being among the statistical representatives of their respective clusters. These results are relevant to balancing the benefits of a new market opportunity woody bioenergy presents with potential adverse implications of over harvesting residual biomass on soil health, water quality, timber health and stand productivity, among others. Moreover, it helps us in understanding the proportion of residual biomass forestland owners are willing to leave unharvested, their sustainability concerns, and policy preferences. The results also account for the relevant socioeconomic factors and complement previous studies that adopt engineering based approaches and solutions Results suggest that forestland owners respond to price offers to change their land use to respond to woody bioenergy by planting new feedstocks. Respondents favoring new pine plantations on their land express interest in learning about the broader contexts of selling biomass for bioenergy such as its tax implications, relevant rules and regulations, and the availability of extension services. Moreover, the results suggest that landowners are interested in maintaining a diverse portfolio of land uses and forest species on their land. Our results also suggest that the experience of having supplied wood for chip-n-saw mills in the past five years, having large land holding, experience with state/federal financial/technical support programs, among others, lead to smaller proportion of non-forested land being allocated for pine. However, a higher price offer, stronger preference for producing non-timber forest products, and lower dependence on working the land for income lead to larger proportion of non-forested land being allocate for pine. These results are relevant to policy makers in developing and improving land use and energy policies, certification programs, and extension and outreach services.

What opportunities for training and professional development has the project provided? This project has helped in training of graduate research assistants (Bernabas Wolde and Pralhad Burli) and one post-doctoral associate (Thomas Ochuodho). How have the results been disseminated to communities of interest? The study results were disseminated through publishing peer-reviewed journal article, book chapters, and oral presentations at academic conferences and seminars. Other community outreach activities include stakeholder meetings with forestland owners in states of Texas, Virginia, and Alabama; Meeting with contractors/loggers; Landowner survey instrument refinement and feedback from university extension professionals engaged in bioenergy research and extension. What do you plan to do during the next reporting period to accomplish the goals? We are currently conducting a more comprehensive assessment of other socioeconomic and forestland features that affect respondents' likelihood of participating in these markets. We plan to finalize the economic analyses of unit costs and profitability of woody biofuels production. We plan to assess the profitability of woody biofuels under more scenarios and using different measures of profitability. We will also evaluate if investors would consider this as a viable investment option by comparing likely returns from other investments in the energy sector and average stock market returns. We will administer landowner surveys in Virginia and Texas and analyze the survey results. We will undertake statistical analyses to better understand the motivations of forestland owners that express willingness to participate in the woody biomass supply market and the limiting factors for those expressing unwillingness to participate in such markets. We will assess respondents' policy preference to better understand the types of incentives for which they will respond. We also plan to assess forestland owners' educational needs, likelihood to change management practices in response to the emergence of woody bioenergy, how prior information affects their policy preference, how past activities may be used to predict planned activities, their sustainability concerns and how that manifests in terms of the amount of residual biomass they are willing to harvest for bioenergy. We believe that these results will be of interest to extension and outreach professionals, forestland owners, managers and other researchers studying the potential economic, social, and ecological impacts associated with the changes forestland owners report as their plans and potential response to woody bioenergy. The income and employment impacts (including total and distributional impacts) of biofuels will be analyzed using the Social Accounting Matrix (SAM) and computable general equilibrium approaches. Techno-economic modeling results along with survey data will be used to calibrate the model for the biofuels sector in the SAM framework and develop biofuel expansion scenarios. We will also undertkae GIS analyses to gauge association between distribution of Loblolly and Slash and pine and counties with significant minority population and which are delineated "persistent poverty counties' by USDA ERS. We willshare project learning's at regional national and international conference and meetings and publish results and submit them to peer-reviewed journals and other outlets so that others professionals can benefit from them.
Impacts
What was accomplished under these goals?
We conducted techno-economic analyses of woody bioenergy from loblolly pine. This included assessment of unit cost of producing biofuel from woody biomass under various scenarios including different feedstock prices, capital costs, conversion efficiencies, co-product values, transportation costs. We are complementing this with a profitability analyses by using different potential market prices and discount rates. We are using state specific values whenever possible to tailor the results, conclusions and recommendations to the relevant states while also trying to maintain some generality. Our results suggest that under some scenarios such as lower discount rate and higher conversion efficiency competitive unit cost and profitably may be achieved. We are currently doing sensitivity analyses where we change the value of certain variables at a time while holding the rest constant to evaluate how sensitive the whole assessment is to changing parameters and to capture performance under changing market conditions. The preliminary results of this analysis suggest that the cost of capital accounts for a significant portion of the unit cost and that financial support programs aimed at this cost component could alleviate the business risk investors might face.We also evaluated the net present value of growing pine for bioenergy under different scenarios of fertilization use, thinning, raking practices, site preparation needs. Our results suggest that forestland owners can viably grow pine for bioenergy under scenarios such as relatively lower site preparation need and with raking, among others. The primary data is being collected through the use of survey instrument based on randomly selected private forestland owners from each state. The Tailored Design Method was adopted for survey administration. We included four different bid values per state in our survey representing per acre woody biomass revenue based on stakeholder meetings, expert feedback and tested through growth and yield models coupled with Timber Mart South price data. The survey covered forested counties in South West Alabama, Virginia, and East Texas. Following previous studies and a consideration that the economics of harvesting from a much smaller land size discourages loggers and forestland owners from actively engaging in biomass marketing practices, we targeted forestland owners holding 20 acres or more. In Alabama, 42 percent of completed survey responses were received from minority landowners.Our results suggest that forestland owners are willing to participate in these markets and that they are responsive to price, where higher price offers lead more forestland owners to participate in these markets. Based on our preliminary analysis we found that for respondents that initially didn't accept the value quoted in the survey, their self-reported minimum acceptable price tend to have a positive and significant effect on the proportion of non-forested land, where for each additional hundred dollars reported by respondents, there was a statistically signifcant increase in the proportion of non-forested land allocated for pine.The preliminary survey results show that the majority of those who responded will consider diverting loblolly pine if they expect returns between $1,200 and $1,700 per acre. If given the price 54% of the respondent will plant some acres of loblolly pine for energy production on non-forest land. As expected, willingness to participate in this market is higher for higher bid price offers. While there is increased willingness to participate in this market for higher bid price offers, which is in line with expectations, some forestland owners expressed reluctance, perhaps owing to strictly defined alternative forest management objectives. complete data analysis will give a clearer picture and delineate other factors that can influence their biomass supply decisions. We applied social accounting matrix (SAM) and Computable General Equilibrium (CGE) model to assess regional economic impacts of bioenergy production in US southeast. CGE models are a class of economic impact models that use economic data to estimate how an economy might react to changes in policies, markets, technologies, or other similar factors. Literature review was meant to arrive at most suitable procedure of "creating" bioenergy sectors from an existing SAM. For the purposes of this study, we identified the following 13 US southeast states as one contiguous land base with potential for bioenergy production. With the help of University of Florida, we acquired 2010 SAM dataset from Impact Analysis for Planning (IMPLAN) for the 13 US southeast states above. The SAM dataset is the basic framework used in CGE modeling. SAM dataset is a square matrix table showing economic data for commodity by industry demand, commodity trade (imports and exports), demographics (number of households by income groupings) among other data categories. We mapped and aggregated the SAM for CGE modeling. SAM data came as transactions between two accounts in 27 separate individual files (for example, demand of each factor of production by individual industries, is one such file) for each of the 13 states. The raw 2010 SAM dataset has 440 industries, 440 commodities, 4 factors, and 20 institutions. For CGE modeling purposes, these have to be "grouped" into some reduced number of the same. A grouping system was defined in a procedure called mapping using General Algebraic Modeling System (GAMS) software (Holland et al. 2007). Mapping procedure therefore detailed in GAMS software codes the way the unaggregated activities (industries), commodities, factors, institutions, and government entities were to be aggregated. Mapping procedure define the sectoring scheme. Aggregation process is where the 440 industries were grouped (grouping common industries together and disaggregating "new" industries from existing ones) into fewer industries. In this case, we aggregated the original 440 industries into 15 industries, which included bioenergy industry sectors. At the moment, bioenergy (from all sources) does not exist as a distinctive commodity/industry sector within IMPLAN SAM database as with the case of conventional energy sectors like coal and electricity. In order to conduct any regional economic assessments of bioenergy production or policy in a CGE model setup, bioenergy sector(s) has/have to exist as own sector(s). For the purposes of model calibration, we assembled forest biomass data for the 13 US southeast states. Model calibration is the process of estimating model parameters such as budget shares in household utility function. Calibration was done by solving the model equations for the parameters of interest using observed values in the SAM of both the endogenous and exogenous variables (Lofgren et al. 2002). Once satisfactory estimates of the parameters for all model were obtained, the model was checked to assure that it adequately performed the functions for which it was intended. The validation process established the credibility of the model by demonstrating its ability to replicate actual observed data.We formulated CGE model which is the process of establishing economic relationships between variables and parameters in the model based on neoclassical economic theory. In this process, model equations and their functional forms (linear and non-linear) were specified. These were written both in mathematical formulation and in GAMS software algorithm codes. In this study, we applied a CGE model developed by Lofgren et al. (2002) and customized by Holland et al. (2007) for compatibility with the IMPLAN to achieve the objective of this study.For actual model analysis and simulations, we shall incorporate biomass data for forest biomass based on landowner survey and techno-economic analyses.

What opportunities for training and professional development has the project provided? This project has helped in training of one graduate research assistant (Bernabas Wolde) and one post-doctoral associate (Thakur Upadhyay). How have the results been disseminated to communities of interest? The study results were disseminated through publishing peer-reviewed journal article, book chapters, and oral presentations at academic conferences. Other community outreach activities include stakeholder meetings with forestland owners were held in states of Texas, Virginia, and Alabama to assess their participation in future bioenergy markets and to facilitate adoption of dedicated bioenergy crops; Focus group discussion with minority landowners was held to gauge their perception about wood based energy and participation in future bioenergy markets; Meeting with contractors/loggers; Landowner survey instrument development and feedback from university extension professionals engaged in bioenergy research and extension; and bioenergy webinar at the trade council for technology and technology support companies. What do you plan to do during the next reporting period to accomplish the goals? Objective 1: Quantitative and qualitative primary data will be collected through the use of survey instrument based on randomly selected private forestland owners from each state. The Tailored Design Method (Dillman, 2007) will be adopted in administering the survey. Given the binomial attribute of the dependent variable in terms of participating or not in bioenergy markets, planting non-forested fields and adopting or not intensive management as a response to bioenergy market, increasing logging activities or not, investing in specialized transportation and processing equipment or not, among others, a logit model will be used. This will identify the factors that statistically explain stakeholders’ responses using their respective socioeconomic, demographic and other relevant attributes. Further, a collective, pairwise and two-way analysis of variance will be used to assess presence of a statistical difference and interaction in response to the survey responses. We will also use statistical technique such as principal component analysis to find a more condensed way of structuring the number of variables by identifying the most significant ones to develop a robust predictive model. We will analyze what type of supply response behavior forestland owners will exhibit in terms of either adopting an intensive silvicultural practice or foresting previously non-forested fields. The literature review on sustainability,markets, sustainability, policies, logging and transportation along the pine feedstock based bioenergy supply chain will be used to develop a white paper. Objective 2: We will assess economics of slash and loblolly pine management for the forestland owner under different scenarios including fertilization and pine raking, the unit cost of producing ethanol from loblolly and slash pine for cellulosic plants under two different capabilities in terms of conversion efficiency and integrated CHP, and its profitability under different scenarios including different discount rate and selling prices. We will estimate the standing forest per acre value, the annual equivalent value, and the land expectation values. We will also estimate of the unit cost of producing an energy equivalent gallon of pine biomass based ethanol. This information can be used to identify the phases of the production cycle that contribute significantly to the overall cost, and identifying alternative inputs and/or production/transportation techniques. We will compare our results with fossil fuel prices. An ethanol plant without a power production capability at 75% conversion efficiency and a plant with a higher conversion efficiency with an onsite power generation capability representing a wide range of present and potential cellulosic ethanol capabilities (Davis et al. 2013) will be used for unit cost analyses. We will conduct sensitivity analyses in terms of feedstock price, excess biomass value, cost of capital, and handling and transportation costs. Objective 3: We will continue our work on the input-output/social accounting matrix (IO/SAM) will be used to assess regional information on employment, industry output, personal income, commodity level supply and demand, state and federal government taxes and spending, capital investment, business inventories, value-added and domestic and foreign trade. We will map and aggregate the SAM for CGE modeling. Other CGE activities will include CGE model formulation, biomass data acquisition and assembling, and CGE model calibration and validation. The GISoverlay for county levelmaps of loblolly and slash pine forest in the study states, minority dominated counties, and persistent poverty counties will be undertaken.
Impacts
What was accomplished under these goals?
Objective 1: We identified those that have stake or interest in bioenergy issues including key supply chain actors such as forestland owners, loggers, transporters, processors, and distributors. We conducted literature review to understand if and how well these stakeholders are willing to participate in woody biomass supply markets. This review also helped identify their priorities, expectations from the sector, the strength, opportunities, threats, challenges they perceive about the sector, and their interaction with others in the forest biomass based bioenergy supply chain. We conducted stakeholder meetings with forestland owners in states of Texas, Virginia, and Alabama to assess their participation in future bioenergy markets and to facilitate adoption of dedicated bioenergy crops.Focus group discussion with minority landowners was held to gauge their perception about wood based energy and participation in future bioenergy markets. Meetings with contractors/loggers were held to discuss their participation in bioenergy markets. We developed the survey instruments that will be used to assess stakeholders participation along the supply chains of forest biomass based biofuels markets in three study states.Thus far, the survey instrument has undergone several rounds of peer reviews from academicians and extension agents. Pilot runs were conducted to determine how forestland owners are likely to respond to it and their suggestions on survey questions were incorporated. The stakeholder meetings in study states were used to develop bid values for landowner survey. Growth and yield model results coupled with price data from Timber Mart South was used to improve per acre stumpage price estimations. The triangulation process also included per acre stumpage price data gathered through sealed bid opening and timber sale award. We reviewed the status of technology and markets, sustainability, policies, and logging and transportation, focusing more on the ways in which forest bioenergy issues have been approached by researchers, and the ensuing results.We are analyzing forest based bioenergy sustainability and policies through intensive literature review comprising the supply chain of pine based biofuels. This review encompasses the entire supply chain—biomass production, harvesting, collection, pretreatment, storage, transporting from the site to the roadside landing, merchandizing and transporting to biomass processors, conversion to advanced biofuels, and delivery to the final consumer. Objective 2: We have prepared manuscript on economics of woody bioenergy as a chapter (Lal and Alavalapati, 2014) in an upcoming book on Handbook of Forest Resource Economics. This work presents a summary of previous studies that apply principles of economics to measure and assess implications of woody bioenergy on the local and regional economies. It summarizes some of the more commonly used tools, findings, and the challenges resulting from varied models and their underlying assumptions. It highlighted some of the areas that have received recent research attention and future research needs required to better inform future public policy. We are conducting economic analyses to assess if conversion facilities can produce cellulosic ethanol at competitive prices. Towards this end, we are assessing the streams of income for a conversion facility from ethanol sales at different prices, capital investment and operating cost analysis to estimate unit cost of producing a gallon of gasoline equivalent cellulosic ethanol. Our preliminary results indicate that cellulosic ethanol can be produced at a competitive price at lower discount rates and prices higher than the unit cost of producing a gasoline equivalent gallon up to the conversion stage. Similarly, our preliminary sensitivity analysis indicates that unit cost of ethanol is significantly influenced by changes in capital return factor and feedstock prices given their proportionally bigger role in the total cost. Such sensitivity of profitability to capital returns factor and feedstock prices may indicate a need for tax credits on capital investments or other forms of assistance to manage risk for conversion facilities. Objective 3: Extensive review of most current literature on application of CGE modeling in bioenergy studies was conducted. Kretschmer and Peterson (2010) conducted an extensive survey on integrating bioenergy into computable general equilibrium models. Their study gives a summary of most recent studies of bioenergy using CGE models. The study also summarizes major issues in modelling bioenergy in CGE models. At the moment, bioenergy does not have its own distinctive account in the SAM but rather it is aggregated as part of other energy sectors, depending on the level of grouping (aggregation) of a particular SAM database. Literature review was meant to arrive at most suitable procedure of “creating” bioenergy sectors from an existing SAM. For the purposes of this study, we identified the following 13 US southeast states as one contiguous land base with potential for bioenergy production. These include: Arkansas Alabama, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, and Virginia. With the help of University of Florida, we acquired 2010 SAM dataset from Impact Analysis for Planning (IMPLAN) for the 13 US southeast states above. The SAM dataset is the basic framework used in CGE modeling. SAM dataset is a square matrix table showing economic data for commodity by industry demand, commodity trade (imports and exports), demographics (number of households by income groupings) among other data categories.
