In an effort to counter this impression, the Agriculture Department of Thailand is seeking to promote the impression that farming is "honorable and secure". However, in Thailand, urbanization has also resulted in massive increases in problems such as obesity. Shifting from

[40] Food deserts in the United States are most commonly found in low-income and predominately African American neighbourhoods. One study on food deserts in Denver , Colorado found that, in addition to minorities,

Food deserts in developed countries often correspond to areas with a high density of fast food chains and convenience stores that offer little to no fresh food. Urbanization has been shown to be associated with the consumption of less fresh fruits, vegetables, and whole grains and a higher consumption of processed foods and sugar-sweetened beverages. Poor access to healthy food and high intakes of fat, sugar and salt are associated with
729-451: A growing increase for addressing other areas of life cycle consumption has occurred from initial stage reduction to heat recovery and recycling of materials. For example, concerns for mass consumption and fast fashion have moved to the forefront of the urban consumers' priorities. Aside from environmental concerns (e.g. climate change effects), other urban concerns for waste management are public health and land access. Urbanization can have
810-459: A higher content of meat, sugars, refined grains and fats. Urban residents typically have reduced time available for at-home food preparation combined with increased disposable income, facilitating access to convenience foods and ready-to-eat meals. One such effect is the formation of food deserts . Nearly 23.5 million people in the United States lack access to supermarkets within one mile of their home. Several studies suggest that long distances to

Rapid growth of communities creates new challenges in the developed world and one such challenge is an increase in food waste also known as urban food waste. Food waste is the disposal of food products that can no longer be used due to unused products, expiration, or spoilage. The increase of food waste can raise environmental concerns such as increase production of methane gases and attraction of disease vectors . Landfills are

In low and middle income countries many factors contribute to the high numbers of people with asthma. Similar to areas in the United States with increasing urbanization, people living in growing cities in low income countries experience high exposure to air pollution, which increases the prevalence and severity of asthma among these populations. Links have been found between exposure to traffic-related air pollution and allergic diseases. Children living in poor, urban areas in

A small private health centre, the Blue Cross Hospital at Rajagiriya, provides basic facilities for medical diagnostics, and there
1215-646: A result of individual, collective and state action. Living in a city can be culturally and economically beneficial since it can provide greater opportunities for access to the labour market, better education, housing, and safety conditions, and reduce the time and expense of commuting and transportation. Conditions like density, proximity, diversity, and marketplace competition are elements of an urban environment that deemed beneficial. However, there are also harmful social phenomena that arise: alienation, stress, increased cost of living, and mass marginalization that are connected to an urban way of living. Suburbanization , which

City life, especially in modern urban slums of the developing world, is certainly hardly immune to pestilence or climatic disturbances such as floods, yet continues to strongly attract migrants. Examples of this were

Throughout the world, as communities transition from rural to more urban societies, the number of people affected by asthma increases. The odds of reduced rates of hospitalization and death from asthmas has decreased for children and young adults in urbanized municipalities in Brazil. This finding indicates that urbanization may have

In cities, money, services, wealth and opportunities are centralized. Many rural inhabitants come to the city to seek their fortune and alter their social position. Businesses, which provide jobs and exchange capital, are more concentrated in urban areas. Whether

Although the two concepts are sometimes used interchangeably, urbanization should be distinguished from urban growth . Urbanization refers to the proportion of the total national population living in areas classified as urban, whereas urban growth strictly refers to

Urban geographers have shown that there exists a large productivity gain due to locating in dense agglomerations. It is thus possible that agents locate in cities in order to benefit from these agglomeration effects. The dominant conurbation (s) of a country can get more benefits from

In the United States, industrialization of agriculture has negatively affected the economy of small and middle-sized farms and strongly reduced the size of the rural labour market. – Madhura Swaminathan, economist at Kolkata's Indian Statistical Institute Particularly in
2349-660: The Overseas Development Institute have proposed policies that encourage labour-intensive to make use of the migration of less skilled workers. One problem these migrant workers are involved with is the growth of slums . In many cases, the rural-urban unskilled migrant workers are attracted by economic opportunities in cities. Unfortunately, they cannot find a job and or pay for houses in urban areas and have to live in slums. Urban problems, along with developments in their facilities, are also fuelling suburb development trends in less developed nations, though

Urbanization can be seen as a specific condition at a set time (e.g. the proportion of total population or area in cities or towns), or as an increase in that condition over time. Therefore, urbanization can be quantified either in terms of the level of urban development relative to the overall population, or as the rate at which the urban proportion of

In addition, children with croup living in urban areas have higher hazard ratios for asthma than similar children living in rural areas. Researchers suggest that this difference in hazard ratios is due to the higher levels of air pollution and exposure to environmental allergens found in urban areas. Exposure to elevated levels of ambient air pollutants such as nitrogen dioxide (NO 2 ), carbon monoxide (CO), and particulate matter with

In children, urbanization is associated with a lower risk of under-nutrition but a higher risk of being overweight . Urbanization has also been linked to the spread of communicable diseases, which can spread more rapidly in the favourable environment with more people living in a smaller area. Such diseases can be respiratory infections and gastrointestinal infections. Other infections could be infections, which need

Overgrowth of algal blooms makes water worse overall and disrupts the natural balance of aquatic ecosystems. Furthermore, as algal blooms die, CO 2 is produced. This makes the ocean more acidic, a process called acidification. The ocean's surface can absorb CO 2 from

Cricket is the most popular sport in this urban area as well as the country and is usually played in the grounds around the city. Association football was at one time the most popular sport in the Colombo area, although it was eclipsed by cricket after 1980. Four separate football clubs (Lido, Welikada Progress, Welikada Red Star and Welikada United) once used

Greater Seoul is one conurbation that dominates South Korea. It is home to 50% of the entire national population. Though Greater Busan-Ulsan (15%, 8 million) and Greater Osaka (14%, 18 million) dominate their respective countries, their populations are moving to their even more dominant rivals, Seoul and Tokyo respectively. As cities develop, costs will skyrocket. This often takes
3888-798: The combination of ill-health and poverty entrenches disadvantage over time." Many of the urban poor have difficulty accessing health services due to their inability to pay for them; so they resort to less qualified and unregulated providers. While urbanization is associated with improvements in public hygiene , sanitation and access to health care , it also entails changes in occupational, dietary , and exercise patterns. It can have mixed effects on health patterns, alleviating some problems, and accentuating others. Traditionally, rural populations have tended to eat plant-based diets rich in grains, fruits and vegetables, and with low fat content. However, rural people migrating to urban areas often shift towards diets that rely more on processed foods characterized by

Depending on the various factors, such as level of urbanization, both increases or decreases in "species richness" can be seen. This means that urbanization may be detrimental to one species but also help facilitate the growth of others. In instances of housing and building development, many times vegetation is completely removed immediately in order to make it easier and less expensive for construction to occur, thereby obliterating any native species in that area. Habitat fragmentation can filter species with limited dispersal capacity. For example, aquatic insects are found to have lower species richness in urban landscapes. The more urbanized

Many people move into cities for economic opportunities, but this does not fully explain the very high recent urbanization rates in places like China and India. Rural flight is a contributing factor to urbanization. In rural areas, often on small family farms or collective farms in villages, it has historically been difficult to access manufactured goods, though
5913-652: The sun's energy is instead absorbed by buildings and asphalt; leading to higher surface temperatures. Vehicles, factories, and heating and cooling units in factories and homes release even more heat. As a result, cities are often 1 to 3 °C (1.8 to 5.4 °F) warmer than other areas near them. Urban heat islands also make the soil drier and absorb less carbon dioxide from emissions. A Qatar University study found that land-surface temperatures in Doha increased annually by 0.65 °C from 2002 to 2013 and 2023. Urban runoff , polluted water created by rainfall on impervious surfaces,
5994-464: The surrounding of habitat is, the fewer species can reach the habitat. Other times, such as with birds, urbanization may allow for an increase in richness when organisms are able to adapt to the new environment. This can be seen in species that may find food while scavenging developed areas or vegetation that has been added after urbanization has occurred i.e. planted trees in city areas – Jack Finegan, Urban Programme Specialist at UN-Habitat In
6075-470: The third leading cause of the release of methane, causing a concern on its impact to our ozone and on the health of individuals. Accumulation of food waste causes increased fermentation, which increases the risk of rodent and bug migration. An increase in migration of disease vectors creates greater potential of disease spreading to humans. Waste management systems vary on all scales from global to local and can also be influenced by lifestyle. Waste management
6156-402: The towns where economic activity consisted primarily of trade at markets and manufactures on a small scale. Due to the primitive and relatively stagnant state of agriculture throughout this period, the ratio of rural to urban population remained at a fixed equilibrium. However, a significant increase in the percentage of the global urban population can be traced in the 1st millennium BCE. With
6237-539: The trend for core cities in said nations tends to continue to become ever denser. Development of cities is often viewed negatively, but there are positives in cutting down on transport costs, creating new job opportunities, providing education and housing, and transportation. Living in cities permits individuals and families to make use of their closeness to workplaces and diversity. While cities have more varied markets and goods than rural areas, facility congestion, domination of one group, high overhead and rental costs, and
6318-513: Was declared open by the former president J. R. Jayewardene . The process of relocating government institutions from the former capital of Colombo is still in progress. The Kotte Urban Development Council was created in the 1930s, with a modern building at Rajagiriya . It was succeeded by the Kotte Urban Council, which had a large section of its area removed and tagged onto the Colombo Municipal Council ward of Borella while
6399-570: Was not a primary concern until after the Industrial Revolution. As urban areas continued to grow along with the human population, proper management of solid waste became an apparent concern. To address these concerns, local governments sought solutions with the lowest economic impacts which meant implementing technical solutions at the very last stage of the process. Current waste management reflects these economically motivated solutions, such as incineration or unregulated landfills. Yet,
6480-533: Was not easy for enemies to enter it. Here, in the 13th century, a local chieftain, Nissanka Alagakkonara , built a Kotte , or fortress. Alagakkonara is mentioned by Ibn Batuta as ruling in Kurunegala , but other sources indicate that he was the Bandara (Guardian) of Raigama Korale (county) in the modern Kalutara District . Arya Chakravarthy's army was held by Alagakkonara in front of Kotte, while he defeated
6561-449: Was the accumulation of hunter-gatherers into villages many thousands of years ago. Village culture is characterized by common bloodlines, intimate relationships, and communal behaviour, whereas urban culture is characterized by distant bloodlines, unfamiliar relations, and competitive behaviour. This unprecedented movement of people is forecast to continue and intensify during the next few decades, mushrooming cities to sizes unthinkable only
