Urban evolution in the USA

On a sustained basis, cities are of non-uniform relative sizes.This paper addresses three basic issues which arise from thissimple observation by examining the size distribution of UScities over the period 1900–1990. First, we explore thereasons why there is a wide distribution of city sizes. Second,we characterize the evolution of the size distribution of cities,documenting growth in sizes and numbers of cities. We ask whetherthe relative size distribution of cities has remained stableover time, or if it has displayed, instead, a tendency to collapse,flatten, or otherwise change its shape. We also examine evidenceon whether the size distribution obeys Zipf's Law. Third, weexamine the degree and determinants of mobility of individualcities within this distribution, asking to what extent citiesare moving up and down in the distribution and how this movementis influenced by cities' geographic characteristics. We usea newly constructed data with consistent metropolitan area definitionsover this century, discussing the issues and linking our resultsto the relevant literature.     

Agricultural Adaptation to Real Regulation on the Urban Fringe: The Chicken Meat Industry's Response to Land‐use Conflict in the Western Port Region of Victoria,Australia

Research theorising the rural‐urban fringe has not focussed in detail on the regulatory system managing land‐use conflict, including disputes arising between agricultural enterprises and residential property owners. To explore local forms of regulation the need to identify relevant actors, their interrelationships and the way that they compete to influence decision‐makers is widely recognised in the literature. Moran et al.'s (1996) conceptualisation of ‘real regulation’, with its emphasis on lobbying by social actors and the (re)formulation of legislation, is identified as a theoretical perspective that can help to explain local forms of regulation. The understanding of patterns of regulation on the urban fringe requires a more detailed conceptualisation of non‐legislative forms of policy, and a greater appreciation of the different strategies adopted by farmers to influence government. This paper investigates how urban fringe agricultural industries have attempted to influence decision‐making within the development approval process. Evidence is presented from the Western Port region in the urban fringe of Melbourne, Victoria, where refusal for the construction of broiler sheds by the Administrative Appeals Tribunal has resulted in the chicken meat industry adopting a more scientific siting strategy. It is concluded that, whilst this provides an example of agricultural adaptation and reinforces the importance of adopting a temporal dimension to investigate the land development process, the possibility that government will assess environmental harm differently in the future leaves urban fringe broiler farming in a precarious position.
