106-432: Urban sprawl , especially between 1945 and 1980, created a vast metropolitan area of over 3,800 km² (1,500 mi²) - or 19 times the area of Buenos Aires proper. The 24 suburban partidos (counties) grew more than six-fold in population between the 1947 and 2022 censuses - or nearly 2.5% annually, compared to 1.4% for the nation as a whole. While annual growth for the suburban area slowed to 0.8% between 2010 and 2022,

212-416: A decline in biodiversity greater than 20% on average. A 2021 study says that just 3% of the planet's terrestrial surface is ecologically and faunally intact, meaning areas with healthy populations of native animal species and little to no human footprint. Many of these intact ecosystems were in areas inhabited by indigenous peoples. With 3.2 billion people affected globally, degradation affects over 30% of

318-411: A depletion of groundwater, as climate change can affect the hydrologic cycle in a number of ways. Uneven distributions of increased temperatures and increased precipitation around the globe results in water surpluses and deficits, but a global decrease in groundwater suggests a rise in sea level, even after meltwater and thermal expansion were accounted for, which can provide a positive feedback to

424-442: A destructive pattern of growth in an endless quest to move away from the sprawl that only results in creating more of it. Urban sprawl is associated with a number of negative environmental outcomes. One of the major environmental problems associated with sprawl is land consumption , habitat loss and subsequent reduction in biodiversity . A review by Brian Czech and colleagues finds that urbanization endangers more species and

530-664: A growing trend in America's metropolitan areas. The Brookings Institution has published multiple articles on the topic. In 2005, author Michael Stoll defined job sprawl simply as jobs located more than 5-mile (8.0 km) radius from the CBD, and measured the concept based on year 2000 U.S. Census data. Other ways of measuring the concept with more detailed rings around the CBD include a 2001 article by Edward Glaeser and Elizabeth Kneebone's 2009 article, which show that sprawling urban peripheries are gaining employment while areas closer to

636-690: A pejorative way. According to the National Resources Inventory (NRI), about 44 million acres (69,000 sq mi; 180,000 km ) of land in the United States was developed between 1982 and 2017. Presently, the NRI classifies approximately 100,000 more square kilometres (40,000 square miles) (an area approximately the size of Kentucky ) as developed than the Census Bureau classifies as urban. The difference in

742-408: A planning approach and those advocating the efficiency of the market". Those who criticize sprawl tend to argue that sprawl creates more problems than it solves and should be more heavily regulated, while proponents argue that markets are producing the economically most efficient settlements possible in most situations, even if problems may exist. However, some market-oriented commentators believe that

848-448: A possible increase in evaporation and evapotranspiration will result, depending on the accompanied rise in temperature. Groundwater reserves will be depleted, and the remaining water has a greater chance of being of poor quality from saline or contaminants on the land surface. Climate change is resulting into a very high rate of land degradation causing enhanced desertification and nutrient deficient soils. The menace of land degradation

954-421: A quarter of the global population is living in an area that is using more than 20% of their renewable water supply; water use will rise with population while the water supply is also being aggravated by decreases in streamflow and groundwater caused by climate change. Even though some areas may see an increase in freshwater supply from an uneven distribution of precipitation increase, an increased use of water supply

1060-642: A rapid rise in water melting from glaciers in the summer, followed by a retreat in glaciers and a decrease in the melt and consequently the water supply every year as the size of these glaciers get smaller and smaller. Thermal expansion of water and increased melting of oceanic glaciers from an increase in temperature gives way to a rise in sea level. This can affect the freshwater supply to coastal areas as well. As river mouths and deltas with higher salinity get pushed further inland, an intrusion of saltwater results in an increase of salinity in reservoirs and aquifers. Sea-level rise may also consequently be caused by

1166-446: A result, the places where people live, work, shop, and recreate are far from one another, usually to the extent that walking, transit use and bicycling are impractical, so all these activities generally require a car. The degree to which different land uses are mixed together is often used as an indicator of sprawl in studies of the subject. According to this criterion, China's urbanization can be classified as "high-density sprawl",

1272-429: A seemingly self-contradictory term coined by New Urbanist Peter Calthorpe . He explains that despite the high-rise buildings, China's superblocks (huge residential blocks) are largely single-use and surrounded by giant arterial roads, which detach different functions of a city and create an environment unfriendly to pedestrians. Job sprawl is another land use symptom of urban sprawl and car-dependent communities. It

1378-417: Is a natural product of population increases, higher wages, and therefore better access to housing. Improvement in transportation also means that individuals are able to live further from large cities and industrial hubs, thus increasing demand for better housing further from the noise of cities. This leads to the creation of sprawling residential land development surrounding densely packed urban areas. Despite

1484-401: Is accompanied by an increase in population demand for natural resources. With the need for more production increases comes more damage to the environments and ecosystems in which those resources are housed. According to United Nations' population growth predictions, there could be up to 170 million more births by 2070. The need for more fuel, energy, food, buildings, and water sources grows with

1590-526: Is an important cause of involuntary migration and forced displacement According to the Food and Agriculture Organization of the United Nations, global greenhouse gas emissions from animal agriculture exceeds that of transportation. Water management is the process of planning, developing, and managing water resources across all water applications, in terms of both quantity and quality." Water management

1696-407: Is an increasing problem due to many foreseen issues in the future including population growth, increased urbanization , higher standards of living , and climate change. Industrial and domestic sewage, pesticides, fertilizers, plankton blooms, silt, oils, chemical residues, radioactive material, and other pollutants are some of the most frequent water pollutants. These have a huge negative impact on

1802-479: Is argued that human beings, while social animals, need significant amounts of social space or they become agitated and aggressive. However, the relationship between higher densities and increased social pathology has been largely discredited. According to Nancy Chin, a large number of effects of sprawl have been discussed in the academic literature in some detail; however, the most contentious issues can be reduced "to an older set of arguments, between those advocating

1908-576: Is commonly linked to increased dependency on cars. In 2003, a British newspaper calculated that urban sprawl would cause an economic loss of £3,905 per year, per person through cars alone, based on data from the RAC estimating that the average cost of operating a car in the UK at that time was £5,000 a year, while train travel (assuming a citizen commutes every day of the year, with a ticket cost of 3 pounds) would be only £1,095. Additionally, increased density increases

2014-431: Is defined as "the spreading of urban developments (such as houses, dense multi–family apartments, office buildings and shopping centers) on undeveloped land near a more or less densely populated city". 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 very dense urban planning . Sometimes

2120-571: Is defined as low-density, geographically spread-out patterns of employment, where the majority of jobs in a given metropolitan area are located outside of the main city's central business district (CBD), and increasingly in the suburban periphery. It is often the result of urban disinvestment , the geographic freedom of employment location allowed by predominantly car-dependent commuting patterns of many American suburbs, and many companies' desire to locate in low-density areas that are often more affordable and offer potential for expansion. Spatial mismatch

2226-414: Is defined by negative characteristics. What constitutes sprawl may be considered a matter of degree and will always be somewhat subjective under many definitions of the term. 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

2332-448: Is directed towards global warming and greenhouse effect , some of the most severe effects of climate change are likely to be from changes in precipitation, evapotranspiration , runoff, and soil moisture. It is generally expected that, on average, global precipitation will increase, with some areas receiving increases and some decreases. Climate models show that while some regions should expect an increase in precipitation, such as in

2438-511: Is due. Thus urban sprawl is subsidized by the tax code. In China, land has been converted from rural to urban use in advance of demand, leading to vacant rural land intended for future development, and eventual urban sprawl. Housing subdivisions are large tracts of land consisting entirely of newly built residences. New Urbanist architectural firm Duany Plater-Zyberk & Company state that housing subdivisions "are sometimes called villages, towns, and neighbourhoods by their developers, which

2544-455: Is expanding rapidly, which together with even more rapid economic growth is the main cause of the degradation of the environment. Humanity's appetite for resources is disrupting the environment's natural equilibrium. Production industries are venting smoke into the atmosphere and discharging chemicals that are polluting water resources. The smoke includes detrimental gases such as carbon monoxide and sulphur dioxide. The high levels of pollution in

2650-470: Is expected. An increased population means increased withdrawals from the water supply for domestic, agricultural, and industrial uses, the largest of these being agriculture, believed to be the major non-climate driver of environmental change and water deterioration. The next 50 years will likely be the last period of rapid agricultural expansion , but the larger and wealthier population over this time will demand more agriculture. Population increase over

2756-684: Is in contrast to New York, San Francisco or Chicago which have compact, high-density cores surrounded by areas of very low-density suburban periphery, such as eastern Suffolk County in the New York metro area and Marin County in the San Francisco Bay Area . Some cases of sprawl challenge the definition of the term and what conditions are necessary for urban growth to be considered sprawl. Metropolitan regions such as Greater Mexico City , Delhi National Capital Region Beijing , and

2862-433: Is increasing by the day and has been characterized as a major global threat. According to Global Assessment of Land Degradation and Improvement (GLADA) a quarter of land area around the globe can now be marked as degraded. Land degradation is supposed to influence lives of 1.5 billion people and 15 billion tons of fertile soil is lost every year due to anthropogenic activities and climate change. The human population on Earth

2968-422: Is misleading since those terms denote places that are not exclusively residential". They are also referred to as developments. Subdivisions often incorporate curved roads and cul-de-sacs . These subdivisions may offer only a few places to enter and exit the development, causing traffic to use high volume collector streets. All trips, no matter how short, must enter the collector road in a suburban system. After

3074-619: Is more geographically ubiquitous in the mainland United States than any other human activity. Urban sprawl is disruptive to native flora & fauna and introduces invasive plants into their environments. Although the effects can be mitigated through careful maintenance of native vegetation, the process of ecological succession and public education, sprawl represents one of the primary threats to biodiversity. Regions with high birth rates and immigration are therefore faced with environmental problems due to unplanned urban growth and emerging megacities such as Kolkata. Other problems include: At

3180-442: Is often regarded unsustainable". Bhatta et al. wrote in 2010 that despite a dispute over the precise definition of sprawl, there is a "general consensus that urban sprawl is characterized by [an] unplanned and uneven pattern of growth, driven by a multitude of processes and leading to inefficient resource utilization". Reid Ewing has shown that sprawl has typically been characterized as urban developments exhibiting at least one of

3286-977: Is one commodity expected to double global food demand by 2050, which directly affects the global supply of fresh water. Cows need water to drink, more if the temperature is high and humidity is low, and more if the production system the cow is in is extensive, since finding food takes more effort. Water is needed in the processing of the meat, and also in the production of feed for the livestock. Manure can contaminate bodies of freshwater, and slaughterhouses, depending on how well they are managed, contribute waste such as blood, fat, hair, and other bodily contents to supplies of fresh water. The transfer of water from agricultural to urban and suburban use raises concerns about agricultural sustainability, rural socioeconomic decline, food security, an increased carbon footprint from imported food, and decreased foreign trade balance. The depletion of fresh water, as applied to more specific and populated areas, increases fresh water scarcity among

3392-416: Is related to job sprawl and economic environmental justice . Spatial mismatch is defined as the situation where poor urban, predominantly minority citizens are left without easy access to entry-level jobs, as a result of increasing job sprawl and limited transportation options to facilitate a reverse commute to the suburbs. Job sprawl has been documented and measured in various ways. It has been shown to be

3498-587: Is supported and guided by institutions, infrastructure, incentives, and information systems The issue of the depletion of fresh water has stimulated increased efforts in water management. While water management systems are often flexible, adaptation to new hydrologic conditions may be very costly. Preventative approaches are necessary to avoid high costs of inefficiency and the need for rehabilitation of water supplies , and innovations to decrease overall demand may be important in planning water sustainability. Water supply systems, as they exist now, were based on

3604-485: Is the depletion of the resource of fresh water on Earth. Approximately only 2.5% of all of the water on Earth is fresh water , with the rest being salt water . 69% of fresh water is frozen in ice caps located on Antarctica and Greenland , so only 30% of the 2.5% of fresh water is available for consumption. Fresh water is an exceptionally important resource, since life on Earth is ultimately dependent on it. Water transports nutrients, minerals and chemicals within

3710-649: Is the shopping mall . Unlike the strip mall, this is usually composed of a single building surrounded by a parking lot that contains multiple shops, usually "anchored" by one or more department stores . The function and size is also distinct from the strip mall. The focus is almost exclusively on recreational shopping rather than daily goods. Shopping malls also tend to serve a wider (regional) public and require higher-order infrastructure such as highway access and can have floorspaces in excess of 1 million sq ft (93,000 m ). Shopping malls are often detrimental to downtown shopping centres of nearby cities since

3816-449: Is the deterioration of the environment through depletion of resources such as quality of air , water and soil ; the destruction of ecosystems ; habitat destruction ; the extinction of wildlife ; and pollution . It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. The environmental degradation process amplifies the impact of environmental issues which leave lasting impacts on

3922-471: Is used for industrial purposes such as processing, washing, and cooling in manufacturing centres. It is estimated that one in three people over the entire globe are already facing water shortages, almost one-fifth of the world population live in areas of physical water scarcity , and almost one quarter of the world's population live in a developing country that lacks the necessary infrastructure to use water from available rivers and aquifers. Water scarcity

4028-826: The Cato Institute , a libertarian think tank , has argued that sprawl, thanks to the automobile, gave rise to affordable suburban neighborhoods for middle class and lower class individuals, including non-whites. He notes that efforts to combat sprawl often result in subsidizing development in wealthier and whiter neighborhoods while condemning and demolishing poorer minority neighborhoods. The American Institute of Architects , American Planning Association , and Smart Growth America recommend against sprawl and instead endorses smart , mixed-use development , including buildings in close proximity to one another that cut down on automobile use, save energy, and promote walkable, healthy, well-designed neighborhoods. The Sierra Club ,

4134-716: The Greater Tokyo Area are often regarded as sprawling despite being relatively dense and mixed use. Many theories speculate as to the reason for the creation of urban sprawl. The theory of "flight from blight" explains that aspects of living in urban areas, such as high taxes, crime rates, poor infrastructure and school qualities lead to many people moving out of urban areas and into surrounding suburban areas. According to The Limits to Growth , reasons why wealthier people move to suburbs include noise, pollution, crime, drug addiction, poverty, labor strikes, and breakdown of social services. Others suggest that Urban Sprawl

4240-559: The Second World War , residential lawns became commonplace in suburbs, notably, but not exclusively in North America. The development of country clubs and golf courses in the early 20th century further promoted lawn culture in the United States. Lawns now take up a significant amount of land in suburban developments, contributing to sprawl. In areas of sprawl, commercial use is generally segregated from other uses. In

4452-415: The urban areas described as the most "sprawling" are the most densely populated. In addition to describing a special form of urbanization , the term also relates to the social and environmental consequences associated with this development. In modern times some suburban areas described as "sprawl" have less detached housing and higher density than the nearby core city . Medieval suburbs suffered from

4558-532: The 10–35 mile ring. This compares to the year 1998 – 23.3%, 34.2%, and 42.5% in those respective rings. The study shows CBD employment share shrinking, and job growth focused in the suburban and exurban outer metropolitan rings. Sprawl often refers to low- density development . There is no precise definition of "low density", but it might commonly mean Single-family homes on large lots. Such buildings usually have fewer stories and are spaced farther apart, separated by lawns , landscaping , roads or parking lots. In

4664-480: The 14 million inhabitants in the entire 30-county area plus the City of Buenos Aires account for a third of the total population of Argentina and generate nearly half (48%) of the country's GDP. The term Gran Buenos Aires ("Greater Buenos Aires") was first officially used in 1948, when Governor of Buenos Aires Province Domingo Mercante signed a bill delineating as such an area covering 14 municipalities surrounding

4770-463: The CBD are losing jobs. These two authors used three geographic rings limited to a 35-mile (56 km) radius around the CBD: 3 miles (4.8 km) or less, 3 to 10 miles (16 km), and 10 to 35 miles (56 km). Kneebone's study showed the following nationwide breakdown for the largest metropolitan areas in 2006: 21.3% of jobs located in the inner ring, 33.6% of jobs in the 3–10 mile ring, and 45.1% in

4876-403: The City of Buenos Aires. The term is also related to other expressions that are not necessarily well-defined: the "Buenos Aires' conurbation" ( Conurbano Bonaerense ), the "Greater Buenos Aires Agglomeration" ( Aglomerado Gran Buenos Aires ), and the "Metropolitan Area of Buenos Aires" ( Área Metropolitana Buenos Aires , AMBA). In colloquial speech, people refer to the "Buenos Aires' conurbation" as

4982-546: The NRI classification is that it includes rural development, which by definition cannot be considered to be "urban" sprawl. Currently, according to the 2000 Census , approximately 2.6 percent of the U.S. land area is urban. Approximately 0.8 percent of the nation's land is in the 37 urbanized areas with more than 1,000,000 population. In 2002, these 37 urbanized areas supported around 40% of the total American population. Nonetheless, some urban areas like Detroit have expanded geographically even while losing population. But it

5088-475: The San Francisco Bay Area's Greenbelt Alliance , 1000 Friends of Oregon and counterpart organizations nationwide, and other environmental organizations oppose sprawl and support investment in existing communities. NumbersUSA , a national organization advocating immigration reduction , also opposes urban sprawl, and its founder, Roy Beck , specializes in the study of this issue. One of

5194-513: The U.S. and Canada, these often take the form of strip malls , which refer to collections of buildings sharing a common parking lot, usually built on a high-capacity roadway with commercial functions (i.e., a "strip"). Similar developments in the United Kingdom are called Retail Parks. Strip malls consisting mostly of big box stores or category killers are sometimes called "power centers" (U.S.). These developments tend to be low-density;

5300-550: The United Nation's IPBES in 2019, posits that roughly one million species of plants and animals face extinction from anthropogenic causes, such as expanding human land use for industrial agriculture and livestock rearing, along with overfishing . Since the establishment of agriculture over 11,000 years ago, humans have altered roughly 70% of the Earth's land surface, with the global biomass of vegetation being reduced by half, and terrestrial animal communities seeing

5406-450: The United States 2–4 houses per acre (5–10 per hectare) might be considered low-density while in the UK 8–12 per acre (or 20–30 per hectare) would still be considered low-density. Because more automobiles are used in the USA, much more land is designated for parking. The impact of low density development in many communities is that developed or "urbanized" land is increasing at a faster rate than

5512-496: The aftermath, greatly increasing their load of unpaid care work. Also, as limited natural resources grow even scarcer due to climate change, women and girls must also walk further to collect food, water or firewood, which heightens their risk of being subjected to gender-based violence. This implies, for example, longer journeys to get primary necessities and greater exposure to the risks of human trafficking, rape, and sexual violence. One major component of environmental degradation

5618-484: The amount of water available to replenish groundwater supplies. Transpiration from plants can be affected by a rise in atmospheric CO 2 , which can decrease their use of water, but can also raise their use of water from possible increases of leaf area. Temperature rise can reduce the snow season in the winter and increase the intensity of the melting snow leading to peak runoff of this, affecting soil moisture, flood and drought risks, and storage capacities depending on

5724-417: The area. Warmer winter temperatures cause a decrease in snowpack , which can result in diminished water resources during summer. This is especially important at mid-latitudes and in mountain regions that depend on glacial runoff to replenish their river systems and groundwater supplies, making these areas increasingly vulnerable to water shortages over time; an increase in temperature will initially result in

5830-508: The assumptions of the current climate, and built to accommodate existing river flows and flood frequencies. Reservoirs are operated based on past hydrologic records, and irrigation systems on historical temperature, water availability, and crop water requirements; these may not be a reliable guide to the future. Re-examining engineering designs, operations, optimizations, and planning, as well as re-evaluating legal, technical, and economic approaches to manage water resources are very important for

5936-412: The atmosphere form layers that are eventually absorbed into the atmosphere. Organic compounds such as chlorofluorocarbons (CFCs) have generated an opening in the ozone layer, which admits higher levels of ultraviolet radiation, putting the globe at risk. The available fresh water being affected by the climate is also being stretched across an ever-increasing global population. It is estimated that almost

6042-457: The average number of residential units per acre in a given area. 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. The term urban sprawl is highly politicized and almost always has negative connotations. It is criticized for causing environmental degradation , intensifying segregation , and undermining

6148-526: The buildings are single-story and there is ample space for parking and access for delivery vehicles. This character is reflected in the spacious landscaping of the parking lots and walkways and clear signage of the retail establishments. Some strip malls are undergoing a transformation into Lifestyle centers ; entailing investments in common areas and facilities (plazas, cafes) and shifting tenancy from daily goods to recreational shopping. Another prominent form of retail development in areas characterized by sprawl

6254-478: The chance that people will take the bicycle for their commute which would be better for their health. Bicycles are a common mode of transportation for those living in urban centers due to many factors. One major factor many people consider relates to how, when one rides a bike to, say, their workplace, they are exercising as they do so. This multi-tasking is better for one's health than automatic transport. A heavy reliance on automobiles increases traffic throughout

6360-491: The city as well as automobile crashes, pedestrian injuries, and air pollution. Motor vehicle crashes are the leading cause of death for Americans between the ages of five and twenty-four and is the leading accident-related cause for all age groups. Residents of more sprawling areas are generally at greater risk of dying in a car crash due to increased exposure to driving. Evidence indicates that pedestrians in sprawling areas are at higher risk than those in denser areas, although

6466-454: The conversion of agricultural land to urban use is not a problem due to the increasing efficiency of agricultural production; they argue that aggregate agricultural production is still more than sufficient to meet global food needs despite the expansion of urban land use. Sprawl leads to increased driving, which in turn leads to vehicle emissions that contribute to air pollution and its attendant negative impacts on human health . In addition,

#1732783515644

6572-611: The current custom of requiring a developer to provide subdivision infrastructure as a condition of development. Usually, the developer is required to set aside a certain percentage of the developed land for public use, including roads, parks and schools. In the past, when a local government built all the streets in a given location, the town could expand without interruption and with a coherent circulation system, because it had condemnation power . Private developers generally do not have such power (although they can sometimes find local governments willing to help), and often choose to develop on

6678-703: The current patterns of sprawl are in fact the result of distortions of the free market. Chin cautions that there is a lack of "reliable empirical evidence to support the arguments made either for or against sprawl". She mentions that the lack of a common definition, the need for more quantitative measures "a broader view both in time and space, and greater comparison with alternative urban forms" would be necessary to draw firmer conclusions and conduct more fruitful debates. Arguments opposing urban sprawl include concrete effects such as health and environmental issues as well as abstract consequences including neighborhood vitality. American public policy analyst Randal O'Toole of

6784-492: The desirability of the area adjacent to such structures. Providing services such as water , sewers , road maintenance, and electricity is also more expensive per household in less dense areas, given that sprawl increases lengths of power lines, roads, and pipes, necessitating higher maintenance costs. Residents of low-density areas spend a higher proportion of their income on transportation than residents of high density areas. The unplanned nature of outward urban development

6890-532: The dismantling of infrastructure that occurred in the United States. Despite its sprawl, Metropolitan Los Angeles is the densest major urban area (over 1,000,000 population) in the US, being denser than the New York urban area and the San Francisco urban area. Most of metropolitan Los Angeles is built at more uniform low to moderate density, leading to a much higher overall density for the entire region. This

6996-626: The distribution of precipitation across the planet is very uneven, causing constant variations in water availability in respective locations. Changes in precipitation affect the timing and magnitude of floods and droughts, shift runoff processes, and alter groundwater recharge rates. Vegetation patterns and growth rates will be directly affected by shifts in precipitation amount and distribution, which will in turn affect agriculture as well as natural ecosystems. Decreased precipitation will deprive areas of water causing water tables to fall and reservoirs of wetlands, rivers, and lakes to empty. In addition,

7102-535: The environment is degraded; direct environmental degradation, such as deforestation, which is readily visible; this can be caused by more indirect process, such as the build up of plastic pollution over time or the buildup of greenhouse gases that causes tipping points in the climate system . Efforts to counteract this problem include environmental protection and environmental resources management . Mismanagement that leads to degradation can also lead to environmental conflict where communities organize in opposition to

7208-639: The environment. Environmental degradation is one of the ten threats officially cautioned by the High-level Panel on Threats, Challenges and Change of the United Nations . The United Nations International Strategy for Disaster Reduction defines environmental degradation as "the reduction of the capacity of the environment to meet social and ecological objectives, and needs". Environmental degradation comes in many types. When natural habitats are destroyed or natural resources are depleted,

7314-442: The extent of modern sprawl has consumed a large amount of the most productive agricultural land, as well as forest, desert and other wilderness areas. In the United States the seller may avoid tax on profit by using a tax break exempting like-kind exchanges from capital gains tax ; proceeds from the sale are used to purchase agricultural land elsewhere and the transaction is treated as a "swap" or trade of like assets and no tax

7420-496: The following characteristics: low-density or single-use development, strip development, scattered development, and/or leapfrog development (areas of development interspersed with vacant land). 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. He proposed using " accessibility " and "functional open space" as indicators. Ewing's approach has been criticized for assuming that sprawl

7526-696: The forces that mismanaged the environment. Scientists assert that human activity has pushed the earth into a sixth mass extinction event. The loss of biodiversity has been attributed in particular to human overpopulation , continued human population growth and overconsumption of natural resources by the world's wealthy. A 2020 report by the World Wildlife Fund found that human activity – specifically overconsumption, population growth and intensive farming – has destroyed 68% of vertebrate wildlife since 1970. The Global Assessment Report on Biodiversity and Ecosystem Services , published by

7632-424: The future of water management in response to water degradation. Another approach is water privatization ; despite its economic and cultural effects, service quality and overall quality of the water can be more easily controlled and distributed. Rationality and sustainability is appropriate, and requires limits to overexploitation and pollution and efforts in conservation. As the world's population increases, it

7738-426: The lack of a clear agreed upon description of what defines sprawl most definitions often associate the following characteristics with sprawl. This refers to a situation where commercial, residential , institutional and industrial areas are separated from one another. Consequently, large tracts of land are devoted to a single use and are segregated from one another by open space, infrastructure, or other barriers. As

7844-593: The larger area consumed by sprawling suburbs compared to urban neighborhoods, more farmland and wildlife habitats are displaced per resident. As forest cover is cleared and covered with impervious surfaces ( concrete and asphalt ) in the suburbs, rainfall is less effectively absorbed into the groundwater aquifers . This threatens both the quality and quantity of water supplies. Sprawl increases water pollution as rain water picks up gasoline , motor oil , heavy metals , and other pollutants in runoff from parking lots and roads. Gordon & Richardson have argued that

7950-480: The last two decades, at least in the United States, has also been accompanied by a shift to an increase in urban areas from rural areas, which concentrates the demand for water into certain areas, and puts stress on the fresh water supply from industrial and human contaminants. Urbanization causes overcrowding and increasingly unsanitary living conditions, especially in developing countries, which in turn exposes an increasingly number of people to disease. About 79% of

8056-407: The loss of protection of city walls, before the advent of industrial warfare . Modern disadvantages and costs include increased travel time, transport costs, pollution, and destruction of the countryside. The revenue for building and maintaining urban infrastructure in these areas are gained mostly through property and sales taxes. Most jobs in the US are now located in suburbs generating much of

8162-433: The natural enemies of pests, soil organisms and wild food species, are in decline as a consequence of the destruction and degradation of habitats, overexploitation, pollution and other threats" and that "key ecosystems that deliver numerous services essential to food and agriculture, including supply of freshwater, protection against hazards and provision of habitat for species such as fish and pollinators, are declining." On

8268-425: The nearness of the workplace to retail and restaurant space that provides cafes and convenience stores with daytime customers is an essential component to the successful balance of urban life. Furthermore, they state that the closeness of the workplace to homes also gives people the option of walking or riding a bicycle to work or school and that without this kind of interaction between the different components of life

8374-544: The number of people on the planet. As the need for new agricultural areas and road construction increases, the deforestation processes stay in effect. Deforestation is the "removal of forest or stand of trees from land that is converted to non-forest use." ( Misplaced Pages-Deforestation ). Since the 1960s, nearly 50% of tropical forests have been destroyed, but this process is not limited to tropical forest areas. Europe's forests are also destroyed by livestock, insects, diseases, invasive species , and other human activities. Many of

8480-534: The output, such as evapotranspiration , surface runoff , drainage, and percolation into groundwater. Changes in climate, especially the changes in precipitation and evapotranspiration predicted by climate models, will directly affect soil moisture, surface runoff, and groundwater recharge . In areas with decreasing precipitation as predicted by the climate models, soil moisture may be substantially reduced. With this in mind, agriculture in most areas already needs irrigation, which depletes fresh water supplies both by

8586-550: The physical use of the water and the degradation agriculture causes to the water. Irrigation increases salt and nutrient content in areas that would not normally be affected, and damages streams and rivers from damming and removal of water. Fertilizer enters both human and livestock waste streams that eventually enter groundwater, while nitrogen, phosphorus, and other chemicals from fertilizer can acidify both soils and water. Certain agricultural demands may increase more than others with an increasingly wealthier global population, and meat

8692-433: The population and also makes populations susceptible to economic, social, and political conflict in a number of ways; rising sea levels forces migration from coastal areas to other areas farther inland, pushing populations closer together breaching borders and other geographical patterns, and agricultural surpluses and deficits from the availability of water induce trade problems and economies of certain areas. Climate change

8798-435: The population is growing. Overall density is often lowered by " leapfrog development". This term refers to the relationship, or lack of it, between subdivisions. Such developments are typically separated by large green belts , i.e. tracts of undeveloped land, resulting in an overall density far lower even than the low density indicated by localized per-acre measurements. This is a 20th and 21st century phenomenon generated by

8904-604: The primary debates around suburban sprawl is the extent to which sprawl is the result of consumer preference. Some, such as Peter Gordon, a professor of planning and economics at the University of Southern California's School of Urban Planning and Development, argue that most households have shown a clear preference for low-density living and that this is a fact that should not be ignored by planners. Gordon and his frequent collaborator, Harry Richardson have argued that Environmental degradation Environmental degradation

9010-484: The problems sea-level rise causes to fresh-water supply. A rise in air temperature results in a rise in water temperature, which is also very significant in water degradation as the water would become more susceptible to bacterial growth . An increase in water temperature can also affect ecosystems greatly because of a species' sensitivity to temperature, and also by inducing changes in a body of water's self-purification system from decreased amounts of dissolved oxygen in

9116-635: The reduced physical activity implied by increased automobile use has negative health consequences. Sprawl significantly predicts chronic medical conditions and health-related quality of life, but not mental health disorders. The American Journal of Public Health and the American Journal of Health Promotion, have both stated that there is a significant connection between sprawl, obesity , and hypertension . Loud vehicles can cause stress, prevent sleep, and minimize social interactions in public for people living in cities (especially homeless people). In

9222-657: The relationship is less clear than for drivers and passengers in vehicles. Research covered in the Journal of Economic Issues and State and Local Government Review shows a link between sprawl and emergency medical services response and fire department response delays. Living in larger, more spread out spaces generally makes public services more expensive. Since car usage becomes endemic and public transport often becomes significantly more expensive, city planners are forced to build highway and parking infrastructure , which in turn decreases taxable land and revenue, and decreases

9328-509: The revenue, although a lack of growth will require higher tax rates. In 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 . There is widespread disagreement about what constitutes sprawl and how to quantify it. For example, some commentators measure sprawl by residential density , using

9434-477: The same time, the urban cores of these and nearly all other major cities in the United States , Western Europe , and Japan that did not annex new territory experienced the related phenomena of falling household size and, particularly in the U.S., " white flight ", sustaining population losses. This trend has slowed somewhat in recent years, as more people have regained an interest in urban living. Due to

9540-476: The set of municipalities that surround the City of Buenos Aires, and which are mostly populated by working-class or middle-class communities. The National Institute of Statistics and Censuses (INDEC) has defined Greater Buenos Aires. There are three main groups within the Buenos Aires conurbation. The first two groups (24 partidos ) comprise the traditional conurbation, or the "conurbation proper", while

9646-628: The shopping malls act as a surrogate for the city centre . Some downtowns have responded to this challenge by building shopping centres of their own. Fast food chains are often built early in areas with low property values where the population is expected to boom and where large traffic is predicted, and set a precedent for future development. Eric Schlosser , in his book Fast Food Nation , argues that fast food chains accelerate suburban sprawl and help set its tone with their expansive parking lots, flashy signs, and plastic architecture (65). Duany Plater Zyberk & Company believe that this reinforces

9752-573: The supply of housing in desirable areas, and thus, it also decreases housing prices in those areas (by the logic of supply and demand ). Urban sprawl may be partly responsible for the decline in social capital in the United States. Compact neighborhoods can foster casual social interactions among neighbors, while sprawl creates barriers. Sprawl tends to replace public spaces with private spaces such as fenced-in backyards. Critics of sprawl maintain that sprawl erodes quality of life . Duany and Plater-Zyberk believe that in traditional neighborhoods

9858-408: The third group of six partidos is in the process of becoming fully integrated with the rest. As urbanization continues and the conurbation grows, six additional partially urbanized partidos (totaling 1,062,991 population of as the 2022 census) are now fully connected with the conurbation : Urban sprawl Urban sprawl (also known as suburban sprawl or urban encroachment )

9964-411: The tracts that happen to be for sale at the time they want to build, rather than pay extra or wait for a more appropriate location. Some research argues that religious ideas about how humans should live (and die) promote low-density development and may contribute to urban sprawl. Land for sprawl is often taken from fertile agricultural lands , which are often located immediately surrounding cities;

10070-406: The tropics and higher latitudes, other areas are expected to see a decrease, such as in the subtropics. This will ultimately cause a latitudinal variation in water distribution. The areas receiving more precipitation are also expected to receive this increase during their winter and actually become drier during their summer, creating even more of a variation of precipitation distribution. Naturally,

10176-603: The urban pattern quickly falls apart. James Howard Kunstler has argued that poor aesthetics in suburban environments make them "places not worth caring about", and that they lack a sense of history and identity. Urban sprawl has class and racial implications in many parts of the world; the relative homogeneity of many sprawl developments may reinforce class and racial divides through residential segregation . Numerous studies link increased population density with increased aggression. Some people believe that increased population density encourages crime and anti-social behavior. It

10282-419: The vitality of existing urban areas, and is attacked on aesthetic grounds. The pejorative meaning of the term means that few openly support urban sprawl as such. The term has become a rallying cry for managing urban growth. The term urban sprawl was often used in the letters between Lewis Mumford and Frederic J. Osborn, firstly by Osborn in his 1941 letter to Mumford and later by Mumford, generally condemning

10388-512: The waste of agricultural land and landscape due to suburban expansions. The term was used in an article in The Times in 1955 as a negative comment on the state of London 's outskirts. Definitions of sprawl vary; researchers in the field acknowledge that the term lacks precision. Batty et al. defined sprawl as "uncoordinated growth: the expansion of community without concern for its consequences, in short, unplanned, incremental urban growth which

10494-476: The water and can cause degradation in various levels. Climate change affects the Earth's water supply in a large number of ways. It is predicted that the mean global temperature will rise in the coming years due to a number of forces affecting the climate. The amount of atmospheric carbon dioxide (CO 2 ) will rise, and both of these will influence water resources; evaporation depends strongly on temperature and moisture availability which can ultimately affect

10600-422: The water due to rises in temperature. A rise in global temperatures is also predicted to correlate with an increase in global precipitation but because of increased runoff, floods, increased rates of soil erosion , and mass movement of land, a decline in water quality is probable, because while water will carry more nutrients it will also carry more contaminants. While most of the attention about climate change

10706-520: The way biodiversity loss and ecosystem degradation impact livelihoods, the Food and Agriculture Organization of the United Nations finds also that in contexts of degraded lands and ecosystems in rural areas, both girls and women bear heavier workloads. Women's livelihoods, health, food and nutrition security, access to water and energy, and coping abilities are all disproportionately affected by environmental degradation. Environmental pressures and shocks, particularly in rural areas, force women to deal with

10812-585: The world's land area and 40% of land in developing countries. The implications of these losses for human livelihoods and wellbeing have raised serious concerns. With regard to the agriculture sector for example, The State of the World's Biodiversity for Food and Agriculture , published by the Food and Agriculture Organization of the United Nations in 2019, states that "countries report that many species that contribute to vital ecosystem services , including pollinators,

10918-399: The world's population is in developing countries, which lack access to sanitary water and sewer systems, giving rises to disease and deaths from contaminated water and increased numbers of disease-carrying insects. Agriculture is dependent on available soil moisture , which is directly affected by climate dynamics, with precipitation being the input in this system and various processes being

11024-419: The world's terrestrial biodiversity can be found living in the different types of forests. Tearing down these areas for increased consumption directly decreases the world's biodiversity of plant and animal species native to those areas. Along with destroying habitats and ecosystems, decreasing the world's forest contributes to the amount of CO 2 in the atmosphere. By taking away forested areas, we are limiting

11130-603: The years following World War II, when vehicle ownership was becoming widespread, public health officials recommended the health benefits of suburbs due to soot and industrial fumes in the city center. However, air in modern suburbs is not necessarily cleaner than air in urban neighborhoods. In fact, the most polluted air is on crowded highways, where people in suburbs tend to spend more time. On average, suburban residents generate more per capita pollution and carbon emissions than their urban counterparts because of their increased driving, as well as larger homes. Sprawl also reduces

11236-496: Was not just urbanized areas in the U.S. that lost population and sprawled substantially. According to data in "Cities and Automobile Dependence" by Kenworthy and Laube (1999), urbanized area population losses occurred while there was an expansion of sprawl between 1970 and 1990 in Amsterdam , Netherlands; Brussels , Belgium; Copenhagen , Denmark; Frankfurt , Hamburg and Munich , Germany; and Zürich , Switzerland, albeit without
