Comprehensive Study Guide on Global Urban Structures and Spatial Development

Essential Urban Geography Concepts and Settlement Classifications\n* Site: Defines the unique physical characteristics of a location, including its climate, available resources, and its absolute location.\n* Situation: Refers to the relative location of a place and its connectivity to other locations through features such as rivers, roads, or ports.\n* Megacity: A large urban settlement with a population exceeding $10$ million people.\n* Metacity: A massive urban area with a total population exceeding $20$ million people.\n* Boomburbs: Rapidly growing suburban cities that may reach a size comparable to a major city while maintaining a distinctly suburban atmosphere.\n* Exurb: A settlement located outside of the traditional suburban buffer that retains a connection to the metropolitan area.\n* Edge cities: Urbanized areas situated on the outskirts of a primary city; they are traditionally connected to major roadways and maintain their own specific economic focus.\n# Theoretical Frameworks of Urban Interaction and Hierarchy\n* Central place theory: States that larger settlements possess a larger range, pulling in consumers from greater distances. This theory is also used to analyze the optimal location of goods and services.\n* Threshold: The specific minimum number of people required to support the continued existence of a particular good or service.\n* Gravity model: Predicts the probability of interaction between two different places. It posits that larger settlements are more likely to see people and other places interact with them.\n* Primate city rule: A hierarchy where the largest settlement has a population that is double that of the second-largest city.\n* Rank Size rule: A pattern where the largest settlement has a population that is half the population more than their second largest settlement.\n# Classical Models of Urban Internal Structure\n* Burgess Concentric-Zone Model: Describes cities as growing outwards from the center in rings. Older homes are located in the center, with newer homes appearing towards the outskirts.\n * $1.$ Central business district\n * $2.$ Zone of transition\n * $3.$ Zone of independent workers homes\n * $4.$ Zone of better residences\n * $5.$ Commuters zone\n* Hoyt Sector Model: Features a city developed in a series of wedges or sectors. The central business district is at the center, and transportation and industry sectors extend through the city from the core.\n * $1.$ Central business district\n * $2.$ Transportation and industry\n * $3.$ Low-class Residential\n * $4.$ Middle-class Residential\n * $5.$ High-class residential\n* Harris and Ullman Multiple Nuclei Model: Features a traditional central business district ($\text{CBD}$) but also recognizes the presence of multiple $\text{CBDs}$ or nodes. Each node attracts specific types of residents and specialized jobs.\n * $1.$ Central Business district\n * $2.$ Wholesale, light manufacturing\n * $3.$ Low class residential\n * $4.$ Medium class residential\n * $5.$ High class residential\n * $6.$ Heavy manufacturing\n * $7.$ Outlying business district\n * $8.$ Residential suburb\n * $9.$ Industrial suburb\n# Modern and Regional Urban Models\n* Galactic (Peripheral) Model: Represents an expansion of the multiple nuclei model where edge cities form prominently outside the central city area.\n * $1.$ Central city\n * $2.$ Suburban Residential Area\n * $3.$ Shopping mall\n * $4.$ Industrial district\n * $5.$ Office park\n * $6.$ Service center\n * $7.$ Airport complex\n * $8.$ Combined Employment and shopping center\n* Latin American city: This model features a prominent \"spine\" that connects the central business district to an elite wealthy shopping district. It also contains a disamenity zone consisting of high-poverty neighborhoods that may lack essential services. Components include:\n * Commercial\n * Market\n * Industrial\n * Zone of Maturity\n * Zone of situ Accretion\n * Zone of peripheral squatter settlements\n * Elite residential sector\n * Gentrification\n * Middle class residential tract\n* Sub Saharan african city model: Characterized by the existence of three separate central business districts ($\text{CBDs}$). It includes informal settlements, such as squatter settlements, around the urban perimeter. Key elements include:\n * Colonial Cbd\n * Market zone\n * Traditional Cbd\n * Major road\n* Southeast asian city model: This model is centered around a port zone, with a government zone that overlooks the daily trade operations. It includes:\n * Squatter areas\n * Suburbs\n * Alien commercial zone\n * Western commercial zone\n# Urban Infrastructure, Challenges, and Socioeconomic Processes\n* Infrastructure and Density Trends: Infrastructure density and verticality increase as one moves closer to the central business district. Conversely, as distance from the cbd increases, there is a prevalence of single-family homes and a marked decrease in public transportation availability.\n* Squatter settlements: Low-income neighborhoods where inhabitants reside without legal claims to the land. These areas are often associated with higher crime rates, informal economies, and a lack of formal infrastructure.\n* New urbanism: An urban planning policy that aims to create walkable, pedestrian-friendly neighborhoods to reduce urban sprawl and enhance affordability for city residents.\n* Green belt: Designated areas where the development of homes and businesses is prohibited to maintain open space.\n* Urban growth boundaries: Regional boundaries established to prevent urban sprawl and contain development within specific limits.\n* Redling: A term used for discriminatory practices regarding the provision of home loans to minority communities.\n* Blockbusting: The unethical practice of convincing property owners to sell their homes cheaply due to the fear of another ethnic or social group moving into the neighborhood, allowing the agitators to resell those properties at a higher price for profit.\n* Gentrification: A complex neighborhood change process where wealthier residents and businesses enter previously less affluent areas, leading to increased property values and the potential displacement of long-term residents.", "title": "Comprehensive Study Guide on Global Urban Structures and Spatial Development"}
