Última Going Digital: Computerized Land Registration and Credit Access in India AgEcon Deininger, Klaus W.; Goyal, Aparajita. Despite strong beliefs that property titling and registration will enhance credit access, empirical evidence in support of such effects remains scant. The gradual roll-out of computerization of land registry systems across Andhra Pradesh’s 387 sub-registry offices (SROs) allows us to combine quarterly administrative data on credit disbursed by all commercial banks for a 11 year period (1997-2007) aggregated to the SRO level with the date of shifting registration from manual to digital. Computerization had no credit effect in rural areas but led to increased credit-supply in urban ones. A marked increase of registered urban mortgages due to computerization supports the robustness of the result. At the same time, estimated impacts from reduction of stamp...

Ano: 2010 URL: http://purl.umn.edu/61257 Forest Carbon Sequestration: Some Issues for Forest Investments AgEcon Sedjo, Roger A.. A major problem being faced by human society is that the global temperature is believed to be rising due to human activity that releases carbon dioxide to the atmosphere; i.e., global warming. The major culprit is thought to be fossil fuel burning, which is releasing increasing amounts of carbon dioxide in the atmosphere. The problem of increasing atmospheric carbon dioxide can be addressed a number of ways. One of these is forestry and forest management. This paper examines a number of current issues related to mitigating the global warming problem through forestry. First, the overall carbon cycle is described, and the potential impact of forests on the buildup of atmospheric carbon is examined. A major focus is the means by which forests and forest...

Ano: 2001 URL: http://purl.umn.edu/10571 Demand-Side Factors in Optimal Land Conservation Choice AgEcon Ando, Amy Whritenour; Shah, Payal. The dominant paradigm of conservation-reserve planning in economics is to optimize the provision of physical conservation benefits (measured in units like species protected) given a budget constraint. Large-scale biology-based priority setting implies that the value we place on biodiversity and ecosystem function is not affected by human proximity to that natural capital. There is significant evidence, however, that human willingness to pay (WTP) for conservation declines with distance (e.g. Loomis 2000) – a phenomenon we refer to as “spatial value decay”. This paper begins a new strand of the conservation planning literature that takes demand-side factors – the location of people in the landscape and the degree to which their willingness to pay for an...

Ano: 2009 URL: http://purl.umn.edu/49209 A note on the performance measure of conservation auctions AgEcon Latacz-Lohmann, Uwe; Schilizzi, Steven. We argue that previous assessments of discriminatory-price conservation auctions may have systematically overestimated their performance relative to uniform-payment schemes due to an inappropriate counterfactual comparison. We demonstrate that the cost curve (and not the bid curve) is the relevant supply curve when a uniform payment is offered and provide a theoretically rigorous counterfactual based on that insight. We estimate that the performance of BushTender may have been overrated by more than 50%.

This paper reports the results of policy simulations of environmental and human health externalities arising from the production of electricity. The primary purpose of this paper is to illustrate the Maryland Externalities Screening and Valuation Model, developed for the State of Maryland's Department of Natural Resources. A secondary purpose is to estimate likely Maryland benefits from Title IV emissions reductions at electric power generation facilities. Sources and scope of benefits, and the potential of policy to achieve specific environmental and human health goals, are suggested by the results. We find that expected health benefits from reductions in power plant emissions dominate the estimated benefits of improved recreational visibility and...

Ano: 1998 URL: http://purl.umn.edu/10825 A spatial bio-economic modelling approach on the trade-offs between global bioenergy demand, agricultural intensification, expansion, and trade AgEcon Lotze-Campen, Hermann; Popp, Alexander; Beringer, Tim; Muller, Christoph; Lucht, Wolfgang. Increased future demands for food, fibre and fuels from biomass can only be met if the available land and water resources on a global scale are used and managed as efficiently as possible. The main routes for making the global agricultural system more productive are through intensification and technological change on currently used agricultural land, land expansion into currently non-agricultural areas, and international trade in agricultural commodities and processed goods. In order to analyse the trade-offs and synergies between these options, we present a global bio-economic modelling approach with a special focus on spatially explicit land and water constraints as well as technological change in agricultural production. For a given bioenergy demand...

The objective of this study is to estimate the impact of natural amenity on farmland values in the contiguous United States using a quantile regression approach and data from the 2006, 2007, and 2008 Agricultural Resource Management Surveys. The contribution of this study is three-fold. First, we explicitly include variables representing natural amenity and soil characteristics of farmland. Second, we employ a quantile regression approach to examine potentially heterogeneous impacts of natural amenity and soil characteristics at different quantiles of farmland values. Third, we utilized data from a nationwide survey of farm household to examine findings in studies using regional data are consistent at a national scale. Our quantile regression analysis...

Ano: 2012 URL: http://purl.umn.edu/119804 Land Degradation in Ethiopia: What do Stoves Have to Do with it? AgEcon Gebreegziabher, Zenebe; van Kooten, G. Cornelis; van Soest, Daan P.. Land degradation is a particularly vexing problem in developing countries; as forests are depleted, crop residues and dung are used for fuel, which degrades cropland. In Ethiopia, the government encourages tree planting and adoption of energy efficient stove technologies to mitigate land degradation. We use data from 200 households in Tigrai, Ethiopia to examine the adoption of new stove technologies. Adoption is an economic decision, related to savings in time spent collecting fuel and cooking, and cattle required for everyday purposes. Results indicate adopters of efficient stoves reduce respective wood and dung use by 68 and 316 kg per month.

Ano: 2005 URL: http://purl.umn.edu/37026 The Ghost of Extinction: Preservation Values and Minimum Viable Population in Wildlife Models AgEcon van Kooten, G. Cornelis; Eiswerth, Mark E.. The inclusion of a minimum viable population in bioeconomic modeling creates at least two complications that are not resolved by using a modified logistic growth function. The first complication can be dealt with by choosing a different depensational growth function. The second complication relates to the inclusion of the in situ benefits of wildlife into the analysis. Knowledge about the magnitude of the in situ benefits provides no guide for policy about conservation management. Simply knowing that people are willing to pay a large amount each year to protect a species says nothing about whether one should manage habitat to protect or enhance the species’ numbers, unless the species is in imminent danger of extinction. If willingness to pay is to be a...

Ano: 2007 URL: http://purl.umn.edu/9790 Hedonic Valuation of Ecosystem Services Using Agricultural Land Prices AgEcon Ma, Shan. Agriculture, an ecosystem transformed by humans for the purpose of supplying food, fiber and biofuel, can provide people a host of benefits, or ecosystem services (ES). While markets exist for farm products, many of today’s central agro-environmental policy concerns are related to ES that lack complete markets, such as regulating ES and recreational, aesthetic and cultural ES. Valuation of non-marketed ES linked to agriculture is needed to improve their utilization and efficient provision. Some ES that facilitate agricultural production or provide natural amenities can be perceived by people through various natural resources and landscapes on farmlands and surrounding areas. One indirect way to measure the value of ES is via what people pay for the lands...

Ano: 2010 URL: http://purl.umn.edu/59321 The Economic Potential of Second-Generation Biofuels: Implications for Social Welfare, Land Use and Greenhouse Gas Emissions in Illinois AgEcon Chen, Xiaoguang; Khanna, Madhu; Onal, Hayri. This paper develops a dynamic micro-economic land use model that maximizes social welfare and internalizes externality from greenhouse gas emissions to obtain the optimal land use allocation for traditional row crops and bioenergy crops (corn stover, miscanthus and switchgrass), the mix of cellulosic feedstocks and fuel and food prices. We use this carbon tax policy as a benchmark to compare the implications of existing biofuel policies on land use, social welfare and the environment for the 2007-2022 period. The model is operationalized using yields of perennial grasses obtained from a biophysical model, county level data on yields of traditional row crops and production costs for row crops and bioenergy crops in Illinois. We show that a carbon tax policy...

Ano: 2009 URL: http://purl.umn.edu/49484 Afforestation and Timber Management Compliance Strategies in Climate Policy. A Computable General Equilibrium Analysis AgEcon Michetti, Melania; Nunes Rosa, Renato. This paper analyzes the role of afforestation-reforestation and timber management activities, and their major and secondary economic effects in stabilizing climate during the first commitment period of the Kyoto Protocol. In particular, with a Computable General Equilibrium framework, the ICES model, it is inferred how forest carbon sequestration fits within the European domestic portfolio of a 2020-20 and 2020-30 climate stabilization policy. Afforestation and land use are accounted for by introducing their effects in the model. This is done by relying on carbon sequestration curves provided by Sohngen (2005), which describe the average annual cost of sequestration for selected world regions. Results show that afforestation and timber management could...

Ano: 2011 URL: http://purl.umn.edu/99641 A Tale of Two Communities: Explaining Deforestation in Mexico AgEcon Alix-Garcia, Jennifer Marie; de Janvry, Alain; Sadoulet, Elisabeth. Explaining land use change in Mexico requires understanding the behavior of the local institutions involved. We develop two theories to explain deforestation in communities with and without forestry projects, where the former involves a process of side payments to non-members of the community and the latter of partial cooperation among community members. Data collected in 2002 combined with satellite imagery are used to test these theories. For the forestry villages, we establish a positive relationship between the distribution of profits as dividends instead of public goods and forest loss. For communities not engaged in forestry projects, deforestation is largely related to the ability of the community to induce the formation of a coalition of members...

In order to evaluate food security, technology potential and the environmental impacts of production in a strategic and regional context, it is critical to have reliable information on the spatial distribution and coincidence of people, agricultural production, and environmental services. This paper proposes a spatial allocation model for generating highly disaggregated, crop-specific production data by a triangulation of any and all relevant background and partial information. This includes national or sub-national crop production statistics, satellite data on land cover, maps of irrigated areas, biophysical crop suitability assessments, population density, secondary data on irrigation and rainfed production systems, cropping intensity, and crop prices....

Ano: 2006 URL: http://purl.umn.edu/25737 Landowner response to policies regulating land improvements: lease or search for other options? AgEcon Eija, Pouta; Sami, Myyra; Kyosti, Pietola. Land improvements with long pay-back periods are often delayed on leased agricultural land, resulting in social costs through land degradation, decreased land productivity and environmental problems. An important question is thus how landowners would respond to regulations and mandates concerning land improvements. Based on a landowner survey, we analyse landowner choices under certain land improvement regulations, using the currently dominant choice of leasing land for agricultural use as the benchmark. The results indicated that land leasing will continue to increase in the future, but if the landowner mandate to co-finance costly land improvements is increased, landowners are predicted to respond significantly to these mandates and search for other land...

Discussions over tropical deforestation are currently at the forefront of climate change policy negotiations at national, regional, and international levels. This paper analyzes the effects of linking Reduced Emissions from Deforestation and Forest Degradation (REDD) to a global market for greenhouse gas emission reductions. We supplement a global climate-energy-economy model with alternative cost estimates for reducing deforestation emissions in order to examine a global program for stabilizing greenhouse gas concentrations at 550 ppmv of CO2 equivalent. Introducing REDD reduces global forestry emissions through 2050 by 20-22% in the Brazil-only case and by 64-88% in the global REDD scenarios. At the same time, REDD lowers the total costs of the...

Ano: 2009 URL: http://purl.umn.edu/52544 Switching to Perennial Energy Crops under Uncertainty and Costly Reversibility AgEcon Song, Feng; Zhao, Jinhua; Swinton, Scott M.. We study a farmer’s decision to convert traditional crop land into growing dedicated energy crops, taking in account sunk conversion costs, uncertainties in traditional and energy crop returns, and learning. The optimal decision rules differ significantly from the expected net present value rule, which ignores learning, and from real option models that allow only one way conversions into energy crops. These models also predict drastically different patterns of land conversions into and out of energy crops over time. Using corn-soybean rotations and switchgrass as examples, we show that the model predictions are sensitive to assumptions about stochastic processes of the returns. Government policies might have unintended consequences: subsidizing conversion...

This paper adopts a real options framework to evaluate the cost-effectiveness of four types of subsidies that aim to encourage a socially desirable land use under return uncertainties and costly reversibility of land use change. We first present a land conversion model to show how the subsidies that are expected net present value (ENPV) equivalent can change a representative farmer’s optimal land conversion rules differently for converting land into an alternative use as well as converting out of it. This is because these subsidies affect the land conversion costs, land return level and uncertainty differently. Then in the context of encouraging energy crop production, we compare the probabilities of inducing the representative farmer to convert land from...

This study identified the factors that influenced whether farmers in the Southeastern United States perceived an improvement in environmental quality from adopting precision farming technologies (PFTs). Farmers with larger farms or higher yields were more likely to believe that they observed positive externalities associated with PFTs. Farmers who found PFTs profitable or who believed input reduction was important had higher probabilities whereas those with higher incomes or who were more dependent on farm income were less likely to perceive such benefits. Interestingly, the importance of environmental quality and length of time using PFTs were not found to affect the probability of perceiving an improvement in environmental quality.
