Modeling Suburban and Rural-Residential Development Beyond the Urban Fringe AgEcon
Newburn, David A.; Berck, Peter.
This article investigates how land-use regulations differentially influence suburban versus ruralresidential development. Particular emphasis is placed on how both the provision of municipal services (e.g., sewer and water) and zoned maximum density constrain higher-density residential development. We estimated a spatially explicit model with parcel data on recent housing development in Sonoma County, California. To account for heterogeneity in compliance with zoning regulations, we used a random-parameter logit model. The designation of sewer and water services was the most important determinant of suburban development. Meanwhile, it did not significantly affect the likelihood of rural-residential development, which actually leapfrogged into areas well...

The economics of agrobiodiversity conservation for food security under climate change AgEcon
Pascual, Unai; Narloch, Ulf; Nordhagen, Stella; Drucker, Adam G..
Subsistence-based and natural resource-dependent societies are especially vulnerable to climate change. In such contexts, food security needs to be strengthened by investing in the adaptability of food systems. This paper looks into the role of agrobiodiversity conservation for food security in the face of climate change. It identifies agrobiodiversity as a key public good that delivers necessary services for human wellbeing. We argue that the public values provided by agrobiodiversity conservation need to be demonstrated and captured. We offer an economic perspective of this challenge and highlight ways of capturing at least a subset of the public values of agrobiodiversity to help adapt to and reduce the vulnerability of subsistence based economies to...

Valuing Farmland Protection with Choice Experiments That Incorporate Preference Heterogeneity: Does Policy Guidance Depend On the Econometric Fine Print? AgEcon
Johnston, Robert J.; Bergstrom, John C..
Although mixed logit models are common in stated preference applications, resulting welfare estimates can be sensitive to minor changes in specification. This can be of critical relevance for policy and welfare analysis, particularly if policymakers are unaware of practical implications. Drawing from an application to agricultural conservation in Georgia, this paper quantifies the sensitivity of welfare estimates to common variations in mixed logit specification and assesses practical implications for policy guidance. Results suggest that practitioners may wish to reevaluate modeling and reporting procedures to reflect the welfare and policy implications of common but often unnoticed variations in model specification.

Aspekte des Gewässerschutzes und der Gewässernutzung beim Anbau von Energiepflanzen - Ergebnisse eines Forschungsvorhabens im Auftrag des Umweltbundesamtes AgEcon
Nitsch, Heike; Osterburg, Bernhard; Buttlar, Christine von; Buttlar, Hans-Bernhard von.
Zusammenfassung: Der vorliegende Arbeitsbericht entstand im Rahmen eines Forschungsvorhabens im Auftrag des Umweltbundesamtes und beleuchtet mit dem Thema „Gewässerschutz und Energiepflanzen“ einen Aspekt, der bisher nicht im Fokus der Diskussionen um den Energiepflanzenanbau stand. In dieser Studie wurden relevante Verwertungsketten für die energetische Nutzung von landwirtschaftlicher Biomasse in Deutschland anhand potenzieller Auswirkungen auf die Gewässer bewertet. Mögliche negative Wirkungen auf die Gewässer sind häufig auch aus Klimaschutzgründen relevant. Vorgestellt werden zudem Möglichkeiten des gewässerschonenden Anbaus. Die Analyse stützt sich auf die Auswertung von Literatur sowie schriftlicher und telefonischer Befragungen verschiedener...

Sustainability of Corn Stover Harvest for Biomass AgEcon
Sesmero, Juan P..
Off-farm demand for crop residues is expected to grow as bioenergy policies become effective. Demand for residues will provide farmers with an additional source of revenue but it may also trigger losses in soil organic carbon and increases in fertilizer application. This study develops a dynamic economic model of stover harvest that permits conceptualization and quantification of these potential tradeoffs. We parameterize our model based on publicly available studies of soil biophysical relationships in the Corn Belt. Under these parameter values and 2010 corn and fertilizer prices harvesting stover is not economically convenient at prices below $53 per dry ton of stover. Results suggest that the rate of stover harvest may be quite sensitive and negatively...

Evidence on the Amenity Value of Wetlands in a Rural Setting AgEcon
Bin, Okmyung; Polasky, Stephen.
This study uses a hedonic property price method to estimate how wetlands affect residential property values in a rural area. The study utilizes wetland inventory data coupled with extensive property sales records between January 2000 and September 2004 from Carteret County, NC. Our results indicate that i) a higher wetland percentage within a quarter mile of a property, ii) closer proximity to the nearest wetland, and iii) larger size of the nearest wetland are associated with lower residential property values. These results contrast with previous hedonic studies that use data from urban areas, which found positive associations between wetland and property values. The amenity value of wetlands appears to depend at least as much on the characteristics of...

Land Preservation in British Columbia: An Empirical Analysis of the Factors Underlying Public Support and Willingness to Pay AgEcon
Androkovich, Robert A.; Desjardins, Ivan; Tarzwell, Gordon; Tsogaris, Peter.
This study extends previous empirical research on land preservation by considering an actual land preservation scheme, the agricultural land reserve in British Columbia, Canada. The reserve was established in 1973 to ensure that development did not occur on the province’s most productive agricultural land. ‘To ensure that local food production is maintained,’ ‘the economic importance of British Columbia’s agricultural sector,’ and ‘to protect the environment’ are the most important factors that underlie support for the reserve. Aggregate, provincewide willingness to pay to maintain the land reserve is substantial, with our most conservative estimate being Can$91.18 million per year.

GENERATING PLAUSIBLE CROP DISTRIBUTION MAPS FOR SUB-SAHARA AFRICA USING SPATIAL ALLOCATION MODEL AgEcon
You, Liangzhi; Wood, Stanley; Wood-Sichra, Ulrike.
Spatial data, which are data that include the coordinates (either by latitude/longitude or by other addressing methods) on the surface of the earth, are essential for agricultural development. As fundamental parameters for agriculture policy research agricultural production statistics by geopolitical units such as country or sub-national entities have been used in many econometric analyses. However, collecting sub-national data is quite difficult in particular for developing countries. Even with great effort and only on regional scales, enormous data gaps exist and are unlikely to be filled. On the other hand, the spatial scale of even the subnational unit is relatively large for detailed spatial analysis. To fill these spatial data gaps we proposed a...

Estimating the Implicit Value of Crop Stubble as a Barrier to Technology Adoption in Morocco AgEcon
Magnan, Nicholas; Larson, Douglas M..
For mixed cereal-livestock farmers, cereal production provides a bundle of goods. Grain is consumed by the household or sold at market, and crop residues are used as livestock feed. The straw component of crop residue can be bought and sold at market and therefore has a well-established local market price. Crop stubble, the portion of the crop residue left on the ground, is generally not traded and therefore has no market price. Some agricultural technologies require farmers to forgo using crop stubble as feed, and cultivation of high value crops entails sacrificing residue production altogether. In this paper we apply a structural econometric model to household data from Morocco to estimate the implicit value of crop stubble. We use a sample splitting...

What Explains the Incidence of the Use of a Common Sediment Control on Lots with Houses Under Construction? AgEcon
Templeton, Scott R.; Sessions, William T.; Haselbach, Liv M.; Campbell, Wallace A.; Hayes, John C..
To analyze compliance with one aspect of the regulation of stormwater discharge, we estimate a random-utility model of the probability that a builder uses a silt fence to control sediments on a lot with a house under construction in an urbanizing county of South Carolina. The probability increases if the builder is responsible to the subdivision’s developer or if a homeowners association exists. The probability also increases as the cost to install a silt fence decreases or the number of houses under construction per built house in a subdivision increases. The results can help county officials target inspection to improve compliance.

Opportunity Costs of Providing Crop Diversity in Organic and Conventional Farming: Would Targeted Environmental Policies Make Economic Sense? AgEcon
Sipilainen, Timo; Huhtala, Anni.
Targeted environmental policies for farmlands may improve the cost-efficiency of conservation programs if one can identify the farms that produce public goods, or environmental outputs, with the least cost. We derive shadow values of producing crop diversity on conventional and organic crop farms to examine their opportunity costs of conservation. Non-parametric distance functions are estimated by applying data envelopment analysis to a sample of Finnish crop farms for the period 1994 – 2002. Our results show that there is variation in the shadow values between farms and the technologies adopted. The extent of cost heterogeneity and farms’ potential for specialization in the production of environmental outputs determine whether voluntary programs such as...

Whole-Farm Evaluation of No-Till Profitability in Rice Production using Mixed Integer Programming AgEcon
Watkins, K. Bradley; Hill, Jason L.; Anders, Merle M.; Windham, Tony E..
Rice production in Arkansas usually involves intensive tillage. No-till rice has been studied, but the focus has been limited to impacts on yields and per acre returns. This study uses mixed integer programming to model optimal machinery selection and evaluate whole-farm profitability of no-till management, for rice-soybean farms. Results indicate that lower machinery ownership expenses combined with lower fuel and labor expenses do enhance the profitability of no-till management, but the monetary gains appear to be modest, implying that other incentives may be necessary to entice producers to use the practice.

Adoption of Soil Conservation Practices in Olive Groves: The Case of Spanish Mountainous Areas AgEcon
Calatrava-Leyva, Javier; Franco, Juan Agustin; Gonzalez-Roa, Maria del Carmen.
This paper presents some results from a survey carried out in 2004 among 223 olive tree farmers from mountainous areas in the Spanish Southern provinces of Granada and Jaen regarding the adoption of soil conservation and management practices. Olive tree groves in mountainous areas are subject to a high risk of soil erosion and have to incur in higher costs of soil conservation. This results in greater difficulties to comply with cross-compliance and to benefit from agri-environmental schemes. Our main objectives are to analyse the current level of adoption of soil conservation practices and to analyse which socio-economic and institutional factors determine such adoption. Three Probit models are estimated. Dependant variables are three different soil...

Recent Trends in Agricultural Land Prices in South Africa: A Preliminary Investigation Using Cointegration Analysis AgEcon
Obi, Ajuruchukwu; van Schalkwyk, Herman D..
The main objective of this paper is to report preliminary findings on the recent trends in agricultural land prices in South Africa against the backdrop of growing concerns over their rising levels. Given the important role of land prices, the impact such increases would have on significant national development efforts, including the on-going land reform programme and other aspects of agricultural restructuring, provide strong justification for this investigation. The cointegration approach was employed within a framework that allowed for both long-run and short-run dynamics of the relationships to be identified. Building on previous structural modelling of farmland prices in the country, and using much expanded time series spanning forty-nine years, it...

Forestry Sequestration of CO2 and Markets for Timber AgEcon
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...

Climate change and food security to 2030: a global economy-wide perspective AgEcon
Valenzuela, Ernesto; Anderson, Kym.
The effects of climate change on agriculture raise major food security concerns. We use a global economy-wide model to assess the effects on farm product prices of expected yield changes. Also modelled is an expected adverse effect of higher temperatures and humidity in the tropics on the productivity of unskilled workers in developing countries. Given the degrees of uncertainty about plausible effects of climate change, our modelling accounts for a range of yield productivity and labor shocks. The results entail consequences for international agricultural prices, national food consumption, self sufficiency, net farm income and economic welfare.

Estimating the Cost of Preserving Private Lands in Florida: An Hedonic Analysis AgEcon
Larkin, Sherry L.; Alavalapati, Janaki R.R.; Shrestha, Ram K..
Florida’s open-space land-acquisition program is one of the most aggressive in the country, with $3.7 billion paid for 3.8 million acres since 1972. Using data from the Conservation and Recreational Lands (CARL) program, hedonic analyses found that acquiring private lands with valuable natural resources, habitat for rare species, and important historical sites for public preservation is more costly. Development potential and pressure also increased acquisition costs. The presence of additional endangered natural elements and needing to contract with additional landowners, however, were found to decrease the cost. Results provide a basis for landowners and land-acquisition agencies to negotiate.

Economics and Biodiversity in Intensively Managed Agro-Ecosystems AgEcon
Russell, Noel P.; Pascual, Unai; Omer, Amani A..
This paper explores the dynamic effects of biodiversity conservation on agricultural production in the context of specialised intensive farming systems. The focus is on the analysis of the dynamic effects of changes in the levels of agrobiodiversity, on technical change and productivity in intensive agricultural systems. A theoretical model is used to derive hypotheses regarding these linkages that are empirically tested using a stochastic production frontier model with data from a panel of UK cereal farms for the period 1989-2000. The results suggest that the increased agrobiodiversity has positively helped to shift the production frontier outwards. This indicates that the evolution of an intensive agricultural system to less intensive use of inputs can...
