This article examines the provision of public goods in an urban area and the effect voting has on the level and location of amenities throughout a city. It is particularly appropriate for small communities that must finance economic development projects with limited funds. The work presented is a result of working with rural communities throughout America that have seen their historic downtowns deteriorate as big box retail grows on the urban fringe. I find this shift in community development may be a result of the way local economic development is financed and projects are decided upon. Specifically, I find significant welfare losses associated with voting for a public good in space. Small public projects that would lead to community-wide welfare...

This paper describes a global model for agriculture and bioenergy (GLOMAB) that incorporates biomass, biofuels and bioelectricity sectors into the GTAP-Energy model by expanding the global GTAP database, production and consumption structures. Biofuels are separated between first- generation (sugar ethanol, starch ethanol) and second- generation (cellulosic ethanol) biofuels and associated biomass feedstocks (maize, sugar cane, crop residues, woody biomass). Beside biofuels, the model also incorporates bioelectricity (as separate form conventional electricity) which competes for the same biomass feedstocks with cellulosic ethanol sector (agricultural residues, woody biomass). With this broad-based representation of the bioenergy system likely to prevail...

This article investigates how land-use regulations differentially influence suburban versus rural-residential 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...

Hurricanes have caused substantial damage in parts of the U.S. Damages are increasing, perhaps as part of a natural cycle or perhaps in part related to global warming. This paper examines the economic damages that hurricanes cause to U.S. agriculture, estimates the increased damage from an increase in hurricane frequency/intensity, and examines the way that sectoral reactions reduce damages. The simulation results show that hurricanes and associated adjustments cause widespread damage and redistribute agricultural welfare. We find that crop mix shifts of vulnerable crops from stricken to nonstricken regions significantly mitigate hurricane damages.

A minimum cross entropy model to generate disaggregated agricultural data at the local level

Xavier, Antonio; Martins, Maria de Belem Costa Freitas; Fragoso, Rui Manuel de Sousa.

This work presents an entropy approach to disaggregate agricultural data at a local level. It comprises two different steps. In a first one, an information prior at disaggregated level based on experts’ opinions, available cartography of land use and biophysical data is created. In a second step, it’s used a minimum cross entropy process in order to manage these information inputs and to guaranty a solution compatible with all the different restrictions. The model was applied to the region of Algarve in the year of 1999, in order to disaggregate the data at the pixel and county level. Results show that the model was able to provide some satisfactory results since the estimated values obtained for the different areas revealed a good approximation to the...

This paper analyses the distributional equality of individual Scottish Government-administered payments in 2008 under CAP Pillars One (single farm payments) and Two (rural development measures) and in total, in terms of economic, social and spatial factors. The analysis shows that 94% of all payments were paid to claimants in core rural areas (94%) while only a few (5%) claimants resided in urban areas or outside of Scotland (1%). However, in both Pillars, claims made by urban residents were often higher than those made by rural dwellers. The Ordinary Least Squares spatial analysis shows that the level of payments was extremely dependent on the geographical location and natural conditions. Spatial factors describing the economic situation in the area of...

Land use change in developing countries is of great interest to policymakers and researchers from many backgrounds. Concerns about consequences of deforestation for global climate change and biodiversity have received the most publicity, but loss of wetlands, declining land productivity, and watershed management are also problems facing developing countries. In developing countries, analysis is especially constrained by lack of data. This paper reviews modeling approaches for data-constrained environments that involve methods such as neural nets and dynamic programming and research results that link individual household survey data with satellite images using geographic positioning systems.

Perception of Land Scarcity by Peri-Urban Farmers

Farmers in peri-urban regions face many problems, among which land scarcity is a major one according to literature. However, as indicated by a survey among farmers in the peri-urban region around Brussels, land scarcity is not perceived as a problem by all farmers to the same extent. Based on econometric analysis, the survey results show that perception of land scarcity is mainly influenced by differences in landownership and perceived ratio between farm land prices and real land prices. Changes in each of these variables will lead to a shift in the problems a farmer faces and will therefore stimulate different farming or land use strategies.

RESUMEN: Estudiamos el precio de la tierra para uso agrario y las variables que determinan su evolución en España, tratando de identificar qué parte de la subida de precios observada se justifica por elementos «internos», relacionados con la renta agraria esperada, y cuál proviene de elementos externos o especulativos, vinculados a cambios en el uso del suelo. Además se relaciona el ciclo de precios con la aceleración de la especialización en el ámbito regional y la integración en la PAC. La novedad de este trabajo consiste en identificar, mediante técnicas de datos de panel, factores no fundamentales (presión urbanizadora, creación de regadíos, cambio demográfico) que, además de los fundamentales (ingresos esperados y localización geográfica) determinan...

Productivity and Efficiency of Corporate and Individual Farms in Ukraine

Lerman, Zvi; Sedik, David J..

The paper presents a comparative analysis of the productivity of corporate and individual farms in Ukraine based primarily on cross-section data from a farm survey conducted by FAO in 2005. We calculate partial land and labor productivity, total factor productivity, and technical efficiency scores (using Stochastic Frontier Analysis) for farms of different organizational forms. Our results demonstrate with considerable confidence that, contrary to established convictions among the Ukrainian decision makers, the large corporate farms are not more productive than the smaller family farms. This finding is not restricted to Ukraine, as a similar result has been obtained by in Moldova, Russia, and the U.S. Policies encouraging a shift from large corporate farms...

In the vicinity of a city, farmers are confronted with increasing agricultural land prices and rents along the rural-urban gradient, but they concurrently enjoy the advantages associated with proximity to a larger and wealthier consumer base. We hypothesize that farmers transition from low-value, land-intensive \traditional" crops to high-value, labor-intensive \specialized" crops on parcels located closer to urban centers. Once returns to development of a parcel exceed the profits associated with farming, exurban farmers may sell their land for conversion to urban use. Urban pressure in the rural-urban fringe intensifies as cities expand. We differentiate between a gradual process of urban growth (or urbanization) and urban sprawl. Utilizing farmland...

The work aims at elaborating an investigative methodology which can highlight the transformation of territorial structures and the social-economic dynamics that influence management of the territory and landscape in order to provide operative instructions for an integrated elaboration of instruments for urban planning and economic programming. The investigation has taken into consideration, using GIS instrument, the evolution of the landscape, of the road network, of the settlements and of the socio-economic system in the period that goes from the early decades of the 19th century to the present period. The territory for analysis is situated along the "internal Marche ridge" of the Apennines, in the province of Ancona (Marche region).

Agricultural land protection near the urban-rural fringe is a goal of many jurisdictions, including British Columbia, Canada, which uses a provincial-wide zoning scheme to prevent subdivisions and non-agricultural uses of the land. Preferential taxes are also used to encourage agricultural use of the land. Small scale hobby farmers are present at the urban fringe near Victoria (the capital), both inside and outside of the Agricultural Land Reserve (ALR). The goal of this paper is to investigate whether hobby farms create problems for agricultural land preservation. We make use of a GIS (geographic information system) model to construct detailed spatial variables and analyse our parcel-level data set using an hedonic pricing model and a limited dependent...

We investigate conceptually and empirically the role of economic incentives in the primary land allocation in China in recent years. A theoretical analysis demonstrates how recent fiscal and governance reforms give rise to land conversion decisions and long run urban spatial sizes much like those generated by competitive land markets with private land ownership. An econometric investigation of Shanghai and the provinces surrounding it demonstrates the presence of rent gradients, often used as an indication of the presence of land markets. It thus appears that economic forces have continued to exercise dominant influence over primary land allocations in spite of recent administrative restrictions on land conversion. These rent gradients are strongest in the...

Using entropy indices and associated bootstrap tests, we describe the distribution of economic sectors across Western European regions over the 1975-2000 period. We decompose geographic concentration into its within-country and between-country components. In addition, we estimate centre-periphery gradients in sectoral location patterns and the impact of EU membership on countries' internal geography. It is found that manufacturing has become gradually more concentrated, although the locational bias towards central regions has become weaker. Conversely, market services have been relocating towards centrally located regions. EU integration appears to have strengthened countries' internal concentration trends.

The paper presents a comparative analysis of the productivity of small and large farms in Moldova based primarily on cross-section data from three farm surveys conducted by the World Bank and USAID in 2000 and 2003. The survey data are supplemented where feasible with time series from official national-level statistics. We calculate partial land and labor productivity, total factor productivity, and technical efficiency scores (using Stochastic Frontier and Data Envelopment Analysis algorithms) for the two categories of small individual farms and large corporate farms. Our results demonstrate with considerable confidence that small individual farms in Moldova are more productive and more efficient than large corporate farms. This finding is not restricted...
