Introduction to World Regional Geography

Introduction to Geography: The Where and the Why

• Defining Geography: While often associated simply with maps and location, geography is the study of both the "where" (location) and the "why" (the reasons behind that location and its characteristics).

  • The Geographic Inquiry: Geographers seek to understand the synthesis of the physical world and human activity. They ask questions regarding why a country is located in a specific spot, why it has a certain shape, how that shape affects its resources and interactions with neighbors, and why its culture or government has developed in a particular style.

  • Etymology: The term originates from the Greek words geo ("the earth") and graphia ("to write").

• Historical Foundations of Geography:

  • Eratosthenes (3rd Century BCE): Commonly known as the "Father of Geography," he wrote a three-volume text titled Geographica. This work included maps of the known world, climate zones, the locations of hundreds of cities, and a coordinate system. He is also credited as the first person to calculate the circumference of the Earth.

  • Ibn Battuta (14th Century CE): A scholar from Morocco who traveled extensively across Africa and Asia, documenting the world's cultures.

  • Muhammad al-Idrisi (Middle Ages): A Muslim geographer who created one of the most advanced world maps of pre-modern times during a period of declining academic inquiry in Europe.

  • Cartography: The scientific study and creation of maps. Early maps (e.g., from Babylon, Polynesia, and the Arabian Peninsula) were primarily used for navigation.

• The Spatial Perspective: Geographer Harm deBlij identified three main ways to view the world:

  • Chronological: Examining the sequence of global events (the historical perspective).

  • Systematic: Exploring societal systems and structures of inequality (the sociological perspective).

  • Spatial: Identifying where things occur and why they occur in those locations (the geographic perspective).

The Spatial Perspective and Tools

• Types of Location:

  • Relative Location: The location of a place in relation to other landmarks (e.g., "the dorm across from the fountain").

  • Absolute Location: An exact point on Earth, typically defined by coordinates or elevation.

• The Geographic Coordinate System:

  • Latitude: Imaginary lines that run laterally, parallel to the equator ($0^{\circ}$), measuring distances north or south of the equator ($90^{\circ}\text{N}$ to $90^{\circ}\text{S}$).

  • Longitude: Lines that converge at the poles and measure distances east and west of the Prime Meridian ($180^{\circ}\text{E}$ to $180^{\circ}\text{W}$).

  • Examples:

    • The White House: latitude $38.8977^{\circ}\text{N}$, longitude $77.0365^{\circ}\text{W}$.

    • The Dead Sea (elevation): The lowest point on land, at $1,378\,\text{feet}$ below sea level.

• Geographic Information Science (GIS): A computer-based system used to capture, store, manipulate, analyze, and present spatial data using satellite imagery and computer technology.

  • Applications: Urban planners use GIS for fire station placement; biologists map bird migration; individuals use it for turn-by-turn navigation by layering roads, buildings, and names.

• Map Projections and Distortion: Because the Earth is a sphere and maps are flat, distortion is inevitable in one of four properties: area, shape, distance, or direction.

  • Mercator Projection: Preserves angles and shapes, making it ideal for navigation, but significantly distorts the size of areas near the poles (e.g., Africa appears smaller relative to Eurasia).

  • Winkel Tripel Projection: Created by Oswald Winkel to minimize distortion in area, direction, and distance. It has been the National Geographic Society's standard world map projection since 1998.

• Scale: The ratio between the distance on a map and the corresponding distance on Earth's surface.

  • Large Scale: Refers to maps that are more "zoomed in," showing smaller areas with more detail (e.g., a $1:5,000$ walking tour map). The ratio ($\frac{1}{5,000}$) is a larger number ($0.0002$).

  • Small Scale: Refers to maps that are more "zoomed out," showing large areas like the whole world (e.g., a $1:50,000,000$ world map). The ratio ($\frac{1}{50,000,000}$) is a smaller number ($0.00000002$).

• Diffusion: The movement or spreading of phenomena across space. This includes the physical movement of people or disease, or the spread of intangible ideas and technology.

Core and Periphery Dynamics

• Regional Interaction: Regions typically consist of a Core and a Hinterland.

  • Core: Often the Central Business District (CBD); an urban area where goods and services are exchanged.

  • Hinterland: The "land behind" the core; a sparsely populated rural area where raw materials are produced and goods for the core are manufactured.

• Global Core and Periphery:

  • Global Core: Dominant, industrialized, and developed areas that exert control over others.

  • Global Periphery: Rural and generally less developed areas.

  • Economic Interaction: Unlike the symbiotic city-hinterland relationship, global core-periphery exchange is often one-sided, creating wealth for the core and maintaining uneven development. Underdevelopment in the periphery keeps goods cheap for core countries.

The Physical Setting

• Branches of Geography:

  • Physical Geography: Focuses on natural features (landforms, climate, water).

  • Human Geography: Focuses on human activity (culture, language, religion).

  • Regional Geography: Uses a holistic approach, synthesizing both physical and human characteristics.

• Plate Tectonics: Earth's surface consists of seven major and several minor rigid plates floating on molten material.

  • Transform Boundary: Plates slide past each other (e.g., San Andreas Fault).

  • Divergent Boundary: Plates slide apart (e.g., Africa's Rift Valley).

  • Convergent Boundary:

    • Plates of similar density collide and move upward to form mountains (e.g., The Himalayas formed by Indian and Eurasian plates).

    • Subduction: One plate slides beneath another, creating deep-ocean trenches (e.g., the 2004 Indian Ocean earthquake/tsunami off Sumatra).

• Topography: The study of the shape and features of the Earth's surface.

  • High Relief: Significant changes in elevation (steep mountains).

  • Low Relief: Relatively flat landscapes.

• Climate and Weather:

  • Weather: Short-term atmospheric conditions (e.g., raining today).

  • Climate: Long-term state of the atmosphere (latitude, terrain, altitude, proximity to water).

  • Köppen Climate Classification System: Uses lettered codes to categorize zones based on temperature and precipitation.

    • High Precipitation: Cherrapunji, India ($Cwb$) receives over $11,000\,\text{mm}$ ($400\,\text{in}$) annually.

    • Aridity: The Atacama Desert ($BWk$) receives only $1$ to $3\,\text{mm}$ ($0.04$ to $0.12\,\text{in}$) per year.

• Global Climate Change: Since the 1800s (Industrial Revolution), the Earth has entered a warming phase.

  • $95\,\%$ of scientists agree human activities (greenhouse gas emissions like $CO_2$) are the primary cause.

  • $17$ of the $18$ warmest years on record have occurred since $2000$.

  • Consequences: Rising sea levels, melting polar caps, changing precipitation, and desert expansion.

The Human Setting and Population

• Global Distribution: World population is approximately $7.4\,\text{billion}$. People cluster in warm areas near water and avoid cold or dry regions.

  • Major Clusters: East Asia, South Asia, and Europe.

• Population Growth Measures:

  • Birth Rate: Live births per $1,000$ people per year ($2012$ global average: $19.15/1,000$).

  • Rate of Natural Increase (RNI): Birth rate minus death rate.

    • Example: Madagascar (Birth: $32.9$, Death: $6.19$) has an RNI of $26.71/1,000$ or $2.671\,\%$.

  • Total Fertility Rate (TFR): Average children per woman during child-bearing years. Developing countries often have a TFR of $4$ or more; developed countries often have $1$ or $2$.

• The Demographic Transition Model (DTM): Represents changes in birth/death rates as a country industrializes.

  • Stage 1: High birth and high death rates; vulnerable to disease/drought. No modern country is currently in Stage 1.

  • Stage 2: High birth rate, declining death rate due to health improvements/vaccines; primarily agricultural. (e.g., most of Sub-Saharan Africa).

  • Stage 3: Declining birth rate due to urbanization and contraceptives; women enter the workforce. (e.g., India, Middle/South America).

  • Stage 4: Birth rates approach death rates; high level of female independence and education. (e.g., China, most of Europe).

  • Stage 5: Birth rate falls below death rate; leads to population decline without immigration. (e.g., Japan, TFR of $1.41$).

• Urbanization: The increasing proportion of people living in urban areas.

  • History: $2009$ marked the first time urban populations surpassed rural populations. By $2014$, $54\,\%$ of the world was urban, projected to reach $66\,\%$ by $2050$.

  • Megacities: Defined as cities with $10\,\text{million}$ or more people. There were $10$ in $1990$ and $28$ in $2014$.

  • Largest Area: Tokyo-Yokohama with over $38\,\text{million}$ inhabitants.

Defining the World's Regions

• Types of Regions:

  • Formal Regions: Areas that share at least one common characteristic (e.g., political boundaries, climate zones like USDA Plant Hardiness zones, religious affiliation).

  • Functional Regions: United by a specific function, often economic. They have a nodal arrangement (core and nodes).

    • Example: Los Angeles Metro. It functions as a single economic unit with over $471,000$ daily commuters into LA County. Other examples: radio listening areas, newspaper subscriptions.

  • Vernacular Regions: Based on people's perceptions and lack strictly defined borders.

    • Example: "The South" in the US or "The Middle East." Boundaries vary depending on who is asked.

• World Regional Divisions: This text identifies nine regions: North America, Middle and South America, Europe, Russia, North Africa and Southwest Asia, Sub-Saharan Africa, South Asia, East and Southeast Asia, and Australia and the Pacific.

• Transition Zones: Real-world regions do not have sharp boundaries; they are marked by gradual spatial change.

  • Example: Moscow is similar to Eastern Europe; the El Paso (Texas)/Ciudad Juárez (Mexico) metro area stretches across two regions and countries.

Sub-Disciplines and Political Geography

• Sub-disciplines of Physical Geography: Biogeography, climatology, hydrology, geomorphology, geodesy (measurement of Earth), and pedology (soil study).

• Sub-disciplines of Human Geography: Cultural, economic, medical, political, population (demography), and urban geography.

• Political Geography Concepts:

  • State: An independent, sovereign political entity (commonly called a "country").

  • Recognition: As of $2019$, there are $206$ states ($193$ UN members). Disputed states include Palestine (observer) and Kosovo.

  • Unitary State: Central government holds the most power (most common globally).

  • Federal State: Power is shared between a national government and regional/self-governing states (e.g., USA, Russia, Brazil).

• Economic Geography Measures:

  • Gross Domestic Product (GDP): Value of all goods and services produced in a country annually.

  • GDP per capita: GDP divided by population (average income).

  • Purchasing Power Parity (PPP): Currency adjustment based on the cost of goods in a country.

  • Gross National Income (GNI): GDP plus income received from overseas.

Globalization and Inequality

• Global Inequality: Approximately half the world lives on less than $\$2$ per day; one-fifth live on less than $\$1$ per day. The wealthiest $1\,\%$ of people own as much as the bottom $99\,\%$.

• Globalization: The process of increased global integration, both economically and culturally.

  • Shrinking World: Advances in transport and communication allow for instant interaction (e.g., US businesswomen video chatting with factory managers abroad).

  • Disparities in Globalization: While global poverty rates fell, the number of poor people in Sub-Saharan Africa increased. Core countries benefit most from diverse trading partners.

  • Cultural Homogenization: Concerns exist that "Western" culture (e.g., American fast food, pop music) is replacing local cultural features, leading to the erasure of traditional music, clothing, and food.
