Landscape Change in the Southern Piedmont: Challenges, Solutions, and Uncertainty Across Scales

The southern Piedmont of the southeastern United States epitomizes the complex and seemingly intractable problems and hard decisions that result from uncontrolled urban and suburban sprawl. Here we consider three recurrent themes in complicated problems involving complex systems: (1) scale dependencies and cross-scale, often nonlinear relationships;     (2) resilience, in particular the potential for complex systems to move to alternate stable states with decreased ecological and/or economic value; and (3) uncertainty in the ability to understand and predict outcomes, perhaps particularly those that occur as a result of human impacts. We consider these issues in the context of landscape-level decision making, using as an example water resources and lotic...

The Impacts of Sprawl on Biodiversity: the Ant Fauna of the Lower Florida Keys
Provedor de dados: Ecology and Society
Autores: Forys, Elizabeth A; Eckerd College; forysea@eckerd.edu; Allen, Craig R; University of Nebraska; allencr@unl.edu.
Sprawling development can affect species composition by increasing the rate of invasion by non-native species, and decreasing the persistence of native species. This paper briefly reviews the scientific literature on the impacts of sprawl on biological diversity, with specific emphasis on the influence of sprawl on non-native species richness. We then explore the relationship between sprawl and biodiversity using a data set of ant species collected from 46 habitat patches located in the increasingly suburbanized Florida Keys, USA. We quantified sprawl as the proximity of roads and amount of development surrounding a habitat patch. Using bait transects, we identified 24 native and 18 non-native species of ants. Neither the overall number of native species...

THE EXTENT OF SPRAWL IN THE FRINGE OF JAKARTA METROPOLITAN AREA FROM THE PERSPECTIVE OF EXTERNALITIES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fitriani,   Rahma; Harris,   Michael.
The Jakarta Metropolitan area has experienced urban sprawl. Existing planning processes do not appear to manage sprawl effectively. The aim of this study is to empirically analyse the contribution of spatial externalities on sprawl, and its effect on proximate agricultural land and conservation areas. A residential location choice model incorporating externalities is constructed, and a Tobit panel data analysis is conducted using grid-based land use data. The analysis finds significant empirical evidence regarding the contribution of neighbourhood development externalities to sprawl. Implications for policy are discussed.

Open Space and Urban Sprawl: The Effects of Zoning and Forest Conservation Regulations in Maryland
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lichtenberg,   Erik.
Rapid urbanization enhances the desirability of policies for preserving open space but policies intended to preserve open space may extend the urban boundary and create leapfrog development. We investigate this potential conflict between open space preservation and urban sprawl conceptually and empirically using data from the Baltimore-Washington suburbs. In accord with previous theoretical and empirical results, the estimated econometric model indicates that both zoning and forest planting requirements contribute to sprawl by increasing the amount of land needed to accommodate the current number of households. These results point to a conflict between preserving open space incorporated into private building lots or internal to sub-divisions and public...

Growth Management Policies for Exurban and Suburban Development: Theory and an Application to Sonoma County, California
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Newburn,   David A.; Berck,   Peter.
This study examines the effectiveness of growth management policies on influencing future patterns of exurban and suburban development. We initially estimate a spatially explicit model of residential development with parcel data in Sonoma County, California. This estimated model is then used to simulate the effect of urban growth boundaries (UGBs) versus allowing municipal sewer service expansion. The UGB policy decreases the amount of suburban development but is less effective in managing exurban development. The downzoning policy in agricultural and resource areas reduces the amount of exurban development, but only partially due to the prevalence of grandfathered lots in rural areas.

DEVELOPMENT AT THE URBAN FRINGE AND BEYOND:  IMPACTS ON AGRICULTURE AND RURAL LAND
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Heimlich,   Ralph E.; Anderson,   William D.
Land development in the United States is following two routes: expansion of urban areas and large-lot development (greater than 1 acre per house) in rural areas. Urban expansion claimed more than 1 million acres per year between 1960 and 1990, yet is not seen as a threat to most farming, although it may reduce production of some high-value or specialty crops. The consequences of continued large–lot development may be less sanguine, since it consumes much more land per unit of housing than the typical suburb. Controlling growth and planning for it are the domains of State and local governments. The Federal Government may be able to help them in such areas as building capacity to plan and control growth, providing financial incentives for channeling growth...
