Urban Area
An urban area is a human settlement with a high population density and an infrastructure of built environment. Urban areas originate through urbanization, and researchers categorize them as cities, towns, conurbations or suburbs. In urbanism, the term "urban area" contrasts to rural areas such as villages and hamlet (place), hamlets; in urban sociology or urban anthropology, it often contrasts with natural environment. The development of earlier predecessors of modern urban areas during the urban revolution of the 4th millennium BCE led to the formation of human civilization and ultimately to modern urban planning, which along with other human activities such as exploitation of natural resources has led to a human impact on the environment. Recent historical growth In 1950, 764 million people (or about 30 percent of the world's 2.5 billion people) lived in urban areas. In 2009, the number of people living in urban areas (3.42 billion) surpassed the number living in rural ...

Urbanization
Urbanization (or urbanisation in British English) is the population shift from Rural area, rural to urban areas, the corresponding decrease in the proportion of people living in rural areas, and the ways in which societies adapt to this change. It can also mean population growth in urban areas instead of rural ones. It is predominantly the process by which towns and City, cities are formed and become larger as more people begin to live and work in central areas. Although the two concepts are sometimes used interchangeably, urbanization should be distinguished from Urban sprawl, urban growth. Urbanization refers to the ''proportion'' of the total national population living in areas classified as urban, whereas urban growth strictly refers to the ''absolute'' number of people living in those areas. It is predicted that by 2050, about 64% of the developing world and 86% of the developed world will be urbanized. This is predicted to generate artificial scarcities of land, lack of dr ...

Public Utilities
A public utility company (usually just utility) is an organization that maintains the infrastructure for a public service (often also providing a service using that infrastructure). Public utilities are subject to forms of public control and regulation ranging from local community-based groups to statewide government monopolies. Public utilities are meant to supply goods and services that are considered essential; water, gas, electricity, telephone, waste disposal, and other communication systems represent much of the public utility market. The transmission lines used in the transportation of electricity, or natural gas pipelines, have natural monopoly characteristics. A monopoly can occur when it finds the best way to minimize its costs through economies of scale to the point where other companies cannot compete with it. For example, if many companies are already offering electricity, the additional installation of a power plant will only disadvantage the consumer as prices ...

Sanitation
Sanitation refers to public health conditions related to clean drinking water and treatment and disposal of human excreta and sewage. Preventing human contact with feces is part of sanitation, as is hand washing with soap. Sanitation systems aim to protect human health by providing a clean environment that will stop the transmission of disease, especially through the fecal–oral route.SuSanA (2008)Towards more sustainable sanitation solutions . Sustainable Sanitation Alliance (SuSanA) For example, diarrhea, a main cause of malnutrition and stunted growth in children, can be reduced through adequate sanitation. There are many other diseases which are easily transmitted in communities that have low levels of sanitation, such as ascariasis (a type of intestinal worm infection or helminthiasis), cholera, hepatitis, polio, schistosomiasis, and trachoma, to name just a few. A range of sanitation technologies and approaches exists. Some examples are community-led total sanita ...

Favela
Favela () is an umbrella name for several types of impoverished neighborhoods in Brazil. The term, which means slum or ghetto, was first used in the Slum of Providência in the center of Rio de Janeiro in the late 19th century, which was built by soldiers who had lived under the favela trees in Bahia and had nowhere to live following the Canudos War. Some of the last settlements were called ''bairros africanos'' (African neighborhoods). Over the years, many former enslaved Africans moved in. Even before the first favela came into being, poor citizens were pushed away from the city and forced to live in the far suburbs. Most modern favelas appeared in the 1970s due to rural exodus, when many people left rural areas of Brazil and moved to cities. Unable to find places to live, many people found themselves in favelas. Census data released in December 2011 by the Brazilian Institute of Geography and Statistics (IBGE) showed that in 2010, about 6 percent of the Brazilian pop ...

Sustainability
Sustainability is a social goal for people to co-exist on Earth over a long period of time. Definitions of this term are disputed and have varied with literature, context, and time. Sustainability usually has three dimensions (or pillars): environmental, economic, and social. Many definitions emphasize the environmental dimension. This can include addressing key environmental problems, including climate change and biodiversity loss. The idea of sustainability can guide decisions at the global, national, organizational, and individual levels. A related concept is that of sustainable development, and the terms are often used to mean the same thing. UNESCO distinguishes the two like this: "''Sustainability'' is often thought of as a long-term goal (i.e. a more sustainable world), while ''sustainable development'' refers to the many processes and pathways to achieve it." Details around the economic dimension of sustainability are controversial. Scholars have discussed this under ...
