Urban planning in the context of "Urbanism"

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 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 BCEled 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.

Urban density is a concept used in urban planning, urban studies, and related fields to describe the intensity of people, jobs, housing units, total floor area of buildings, or some other measure of human occupation, activity, and development across a defined unit of area. In general terms, urban density describes the degree of concentration or compactness of people or development in a city. As such it is to be distinguished from other measures of population density. Urban density is considered an important factor in understanding how cities function. Research related to urban density occurs across diverse areas, including economics, health, innovation, psychology and geography as well as sustainability.

A 2019 meta-analysis of 180 studies on a vast number of economic outcomes of urban density concluded that urban density had net positive effects. However, there may be some regressive distributional effects.

The compact city or city of short distances is an urban planning and urban design concept, which promotes relatively high residential density with mixed land uses. It is based on an efficient public transport system and has an urban layout which – according to its advocates – encourages walking and cycling, low energy consumption and reduced pollution. A large resident population provides opportunities for social interaction as well as a feeling of safety in numbers and "eyes on the street". It is also arguably a more sustainable urban settlement type than urban sprawl because it is less dependent on the car, requiring less (and cheaper per capita) infrastructure provision (Williams 2000, cited in Dempsey 2010).

Achieving a compact city does not just mean increasing urban density per se or across all parts of the city. It means good planning to achieve an overall more compact urban form:

The term built environment refers to human-made conditions and is often used in architecture, landscape architecture, urban planning, public health, sociology, and anthropology, among others. These curated spaces provide the setting for human activity and were created to fulfill human desires and needs. The term can refer to a plethora of components including the traditionally associated buildings, cities, public infrastructure, transportation, open space, as well as more conceptual components like farmlands, dammed rivers, wildlife management, and even domesticated animals.

The built environment is made up of physical features. However, when studied, the built environment often highlights the connection between physical space and social consequences. It impacts the environment and how society physically maneuvers and functions, as well as less tangible aspects of society such as socioeconomic inequity and health. Various aspects of the built environment contribute to scholarship on housing and segregation, physical activity, food access, climate change, and environmental racism.

Urban sociology is the sociological study of cities and urban life. One of the field’s oldest sub-disciplines, urban sociology studies and examines the social, historical, political, cultural, economic, and environmental forces that have shaped urban environments.Like most areas of sociology, urban sociologists use statistical analysis, observation, archival research, census data, social theory, interviews, and other methods to study a range of topics, including poverty, racial residential segregation, economic development, migration and demographic trends, gentrification, homelessness, blight and crime, urban decline, and neighborhood changes and revitalization. Urban sociological analysis provides critical insights that shape and guide urban planning and policy-making.

The philosophical foundations of modern urban sociology originate from the work of sociologists such as Karl Marx, Ferdinand Tönnies, Émile Durkheim, Max Weber and Georg Simmel who studied and theorized the economic, social and cultural processes of urbanization and its effects on social alienation, class formation, and the production or destruction of collective and individual identities.

The decentralized administrations (Greek: αποκεντρωμένες διοικήσεις, romanized: apokentroménes dioikíseis) is a tier of the Greek public administration of Greece. They are not elected governing bodies, but are appointed by the national government to supervise the regions and municipalities within their territory. They were created in January 2011 as part of a far-reaching reform of the country's administrative structure, the Kallikratis reform (Law 3852/2010).

They are run by a government-appointed general secretary, assisted by an advisory council drawn from the regional governors and the representatives of the municipalities. They enjoy both administrative and financial autonomy and exercise devolved state powers in urban planning, environmental and energy policy, forestry, migration and citizenship. Beyond that, they are tasked with supervising the first and second-level self-governing bodies, the regions and municipalities.

Sir Patrick Geddes FRSE (2 October 1854 – 17 April 1932) was a Scottish biologist, sociologist, Comtean positivist, geographer, philanthropist and pioneering town planner. He is known for his innovative thinking in the fields of urban planning and sociology. His works contain one of the earliest examples of the 'think globally, act locally' concept in social science.

Following the philosophies of Auguste Comte and Frederic Le Play, he introduced the concept of "region" to architecture and planning and coined the term "conurbation". Later, he elaborated "neotechnics" as the way of remaking a world apart from over-commercialization and money dominance.
