Secondary City
A secondary city often follows after a primate city and can be seen in the urban hierarchy. Secondary cities often have between “500,000 to 3 million inhabitants, but are frequently unknown outside of their national or regional context. Many secondary cities in the Global South are expected to undergo massive expansions in the next few decades, comparable to city growth in Europe and North America over the past two centuries. "A secondary city is largely determined by population, size, function, and economic status. Commonly, secondary cities are geographically defined urban jurisdictions or centres performing vital governance, logistical, and production functions at a sub-national or sub-metropolitan region level within a system of cities in a country. In some cases, their role and functions may expand to a geographic region of the global realm. The population of secondary-cities range between 10 and 50% of a country's largest city, although some can be smaller than this. They wi ...

Primate City
A primate city is a city that is the largest in its country, province, Federated state, state, or region, and disproportionately larger than any others in the urban hierarchy. A ''primate city distribution'' is a rank-size distribution that has one very large city with many much smaller cities and towns, and no intermediate-sized urban centers: a king effect, visible as an outlier on an otherwise linear graph, when the rest of the data fit a power law or stretched exponential function. The ''law of the primate city'' was first proposed by the geographer Mark Jefferson (geographer), Mark Jefferson in 1939. He defines a primate city as being "at least twice as large as the next largest city and more than twice as significant." Aside from size and population, a primate city will usually have precedence in all other aspects of its country's society such as economics, politics, culture, and education. Primate cities also serve as targets for the majority of a country or region's intern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Hierarchy
The urban hierarchy ranks each city based on the size of population residing within the nationally defined statistical urban area. Because urban population depends on how governments define their metropolitan areas, urban hierarchies are conventionally ranked at the national level; however, the ranking can be extended globally to include all cities. Urban hierarchies tell us about the general organization of cities and yield some important insights. First, it tells us that within a system of cities, some cities will grow to be very large, but that number will be small relative to the universe of cities. Second, it refutes the expectation of an optimally sized city. Lastly, it establishes cities as belonging to an inter-related network where one city's growth affects others'. Theoretical distribution The hierarchy is usually related to the empirical regularity with which cities are distributed. The pattern has been formulated in a number of ways, but usually as a variation of the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global South
The concept of Global North and Global South (or North–South divide in a global context) is used to describe a grouping of countries along socio-economic and political characteristics. The Global South is a term often used to identify regions within Latin America, Asia, Africa, and Oceania. It is one of a family of terms, including "Third World" and "Periphery", that denote regions outside Europe and North America. Most, though not all, of these countries are low-income and often politically or culturally marginalized on one side of the divide, while on the other side are the countries of the Global North (often equated with developed countries). As such, the term does not inherently refer to a geographical south; for example, most of the Global South is geographically within the Northern Hemisphere. The term as used by governmental and developmental organizations was first introduced as a more open and value-free alternative to "Third World" and similarly potentially "valuin ...

UN-HABITAT
The United Nations Human Settlements Programme (UN-Habitat) is the United Nations programme for human settlements and sustainable urban development. It was established in 1977 as an outcome of the first United Nations Conference on Human Settlements and Sustainable Urban Development (Habitat I) held in Vancouver, Canada, in 1976. UN-Habitat maintains its headquarters at the United Nations Office at Nairobi, Kenya. It is mandated by the United Nations General Assembly to promote socially and environmentally sustainable towns and cities with the goal of providing adequate shelter for all. It is a member of the United Nations Development Group. The mandate of UN-Habitat derives from the Habitat Agenda, adopted by the United Nations Conference on Human Settlements (Habitat II) in Istanbul, Turkey, in 1996. The twin goals of the Habitat Agenda are adequate shelter for all and the development of sustainable human settlements in an urbanizing world. Overview The UN-Habitat mandate i ...

Lynd Professor of Sociology at Columbia University in New York City, and Centennial visiting Professor at the London School of Economics. The term '' global city'' was coined and popularized by Sassen in her 1991 work, ''The Global City: New York, London, Tokyo''. Family and early life Sassen was born in The Hague, Netherlands in 1947. In 1948, Sassen's parents, Willem Sassen and Miep van der Voort, moved to Argentina and the family lived in Buenos Aires. Her father was a Dutch collaborator with the Nazis, a Nazi journalist, and a member of the ''Waffen-SS''. In the 1950s, Willem Sassen was close to Adolf Eichmann when both were living in Argentina, and she recalls him visiting her childhood home. This association caused her and her mother to leave Argentina while she was still a child. Saskia Sassen spent part of her ...

Urban Planning
Urban planning, also known as town planning, city planning, regional planning, or rural planning, is a technical and political process that is focused on the development and design of land use and the built environment, including air, water, and the infrastructure passing into and out of urban areas, such as transportation, communications, and distribution networks and their accessibility. Traditionally, urban planning followed a top-down approach in master planning the physical layout of human settlements. The primary concern was the public welfare, which included considerations of efficiency, sanitation, protection and use of the environment, as well as effects of the master plans on the social and economic activities. Over time, urban planning has adopted a focus on the social and environmental bottom-lines that focus on planning as a tool to improve the health and well-being of people while maintaining sustainability standards. Sustainable development was added as one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
