![]() Ewing has also argued that suburban development does not, per se constitute sprawl depending on the form it takes, although Gordon & Richardson have argued that the term is sometimes used synonymously with suburbanization in a pejorative way. What constitutes sprawl may be considered a matter of degree and will always be somewhat subjective under many definitions of the term. Ewing's approach has been criticized for assuming that sprawl is defined by negative characteristics. ![]() He proposed using " accessibility" and "functional open space" as indicators. He argued that a better way to identify sprawl was to use indicators rather than characteristics because this was a more flexible and less arbitrary method. Reid Ewing has shown that sprawl has typically been characterized as urban developments exhibiting at least one of the following characteristics: low-density or single-use development, strip development, scattered development, and/or leapfrog development (areas of development interspersed with vacant land). wrote in 2010 that despite a dispute over the precise definition of sprawl, there is a "general consensus that urban sprawl is characterized by unplanned and uneven pattern of growth, driven by a multitude of processes and leading to inefficient resource utilization." defined sprawl as "uncoordinated growth: the expansion of community without concern for its consequences, in short, unplanned, incremental urban growth which is often regarded unsustainable." Bhatta et al. Definitions of sprawl vary researchers in the field acknowledge that the term lacks precision. The term "urban sprawl" was first used in an article in The Times in 1955 as a negative comment on the state of London's outskirts. Measures for urban sprawl in Europe: upper left the Dispersion of the built-up area (DIS), upper right the weighted urban proliferation (WUP) ![]() The term has become a rallying cry for managing urban growth. The pejorative meaning of the term means that few openly support urban sprawl as such. It is criticized for causing environmental degradation, intensifying segregation, and undermining the vitality of existing urban areas and is attacked on aesthetic grounds. The term urban sprawl is highly politicized and almost always has negative connotations. Others associate it with decentralization (spread of population without a well-defined centre), discontinuity ( leapfrogging development, as defined below), segregation of uses, and so forth. For example, some commentators measure sprawl by residential density, using the average number of residential units per acre in a given area. There is widespread disagreement about what constitutes sprawl and how to quantify it. In Continental Europe, the term peri-urbanisation is often used to denote similar dynamics and phenomena, but the term urban sprawl is currently being used by the European Environment Agency. The cost of building urban infrastructure for new developments is hardly ever recouped through property taxes, amounting to a subsidy for the developers and new residents at the expense of existing property taxpayers. Modern disadvantages and costs include increased travel time, transport costs, pollution, and destruction of countryside. Medieval suburbs suffered from loss of protection of city walls, before the advent of industrial warfare. In addition to describing a special form of urbanization, the term also relates to the social and environmental consequences associated with this development. Urban sprawl has been described as the unrestricted growth in many urban areas of housing, commercial development, and roads over large expanses of land, with little concern for urban planning. Urban sprawl (also known as suburban sprawl or urban encroachment ) is defined as "the spreading of urban developments (such as houses and shopping centers) on undeveloped land near a city". Expansion of auto-oriented, low-density development in suburbs
