Geography as a discipline

  • The term 'Geography' was coined by the Greek scholar Eratosthenes in the third century BCE. It represents a scientific field dedicated to exploring the lands, features, and phenomena of Earth. 

Introduction to Geography:

  • The word "Geography" originates from the Greek language, where "Geo" means Earth and "graphos" means description, collectively referring to the description of the Earth.
  • Geography involves the integrated study of nature and human interactions, leaving its mark on aspects like food, clothing, shelter, and occupation. Human adaptation and modification form the foundation of our relationship with nature.
  • Geographical phenomena are not static; they are highly dynamic, evolving over time due to interactive processes.

Various geographers have provided their definitions:

  • Richard Hartshorne defines Geography as being concerned with describing and explaining the differentiation of the Earth's surface.
  • Alfred Hettner states that Geography studies the differences in phenomena occurring in different parts of the Earth's surface.
  • Strabo views Geography as an independent subject with the purpose of imparting knowledge about the world, celestial bodies, land, ocean, animals, plants, fruits, and everything observed in the Earth's regions.
  • Ptolemy describes Geography as the marvelous science of glimpsing the Earth in heaven.

Geography as an Integrating Discipline

Geography serves as a unifying discipline, employing spatial synthesis and adopting a holistic approach. Recognizing the world's interdependence, geography seeks to comprehend the associations among phenomena within the framework of reality sections. As every scientific discipline deals with elements that vary over space, geography aids in grasping reality entirely from a spatial perspective.

Geography as a Relation to Human and Environment 

  • In the early 20th century, geography evolved as an exploration of the relationship between humans and the environment. Two contrasting concepts emerged during this period:
    • Concept of Determinism: This notion posits that the physical environment exerts a massive and controlling influence on humans, leaving them no choice but to adhere to nature's dictates. Friedrich Ratzel and Ellsworth Huntington supported this ideology.
    • Concept of Possibilism: In reaction to determinism, possibilism explains the human-environment relationship differently, viewing humans as active agents capable of shaping their surroundings. Vedal de La Blache and Lucien Febvre endorsed this ideology.

Concept of Neo-Determinism

  • The Concept of Neo-Determinism, introduced by geographer Griffith Taylor in the 1920s, strikes a middle ground between environmental determinism and possibilism, often termed as stop-and-go determinism.

Development of geography

  • The development of geography dates back to the earliest records when scholars focused on understanding the Earth's physical domain through map-making and astronomical measurements. 
  • Ancient Greeks, including Hower, Herodotus, Thales, Aristotle, and Eratosthenes, are credited as early geographers. 
  • The explorers and travelers from the 15th to the early 18th century, such as Columbus, Vasco da Gama, Magellan, and Thomas Cook, contributed significantly. Modern geography was shaped by Varenius, Kant, Humboldt, and Ritter, often considered the founders of modern geography.
  • The post-Second World War period witnessed rapid development in geography. Hartshorne defined geography as a science dealing with areal differentiation. 

Branches of Geography

  • In contemporary geography, the regional and systematic approaches are viewed as complementary rather than contradictory.
  • Geography, as an interdisciplinary subject, employs major approaches, including the systematic and regional approaches:
  • Systematic Approach: This involves studying specific natural or human phenomena that give rise to spatial patterns and structures on Earth's surface. Alexander Von Humboldt introduced this approach.
  • In systematic approach, a phenomenon is studied world over as a whole and then the identification of All typologies or spatial patterns is Based on systematic approach geography can be classified as

Physical Geography

Physical Geography encompasses various subfields that focus on understanding different aspects of the Earth's physical environment:

  • Geomorphology: Devoted to the study of landforms, their evolution, and related processes.
  • Climatology: Encompasses the study of the structure of the atmosphere, elements of weather, climate types, and regions.
  • Hydrology: Studies the realm of water, including oceans, lakes, rivers, and other water bodies, and its effects on different life forms, including human activities.
  • Soil Geography: Concerned with the distribution and variability of soils on terrestrial landscapes ranging from local to global scales.

The Geography of Principles/Philosophy

The Geography of Principles/Philosophy delves into the foundational aspects of geography:

  • Geographical Thought: Encompasses the historical development of geographic knowledge in specific places, times, and contexts, primarily approached from a historical perspective.
  • Human Ecology: An interdisciplinary study of the relationship between humans and their natural, social, and built environments, involving advancements in ecology, geography, sociology, psychology, anthropology, zoology, public health, and home economics.

The Geography of Methods/Techniques

The Geography of Methods/Techniques focuses on methodologies and techniques used in geographic studies:

  • Cartography: The study of the conception, production, dissemination, and analysis of maps.
  • Quantitative Techniques: Methods used in quantitative geography, including geographic information systems (GIS) for mapping, analysis, and optimization, useful in airborne sensing, statistics, exploratory spatial data analysis, mathematics, and regional analysis.
  • Field Survey Methods: Basic procedures involving observation, sketching, measurement, interviews, etc., to understand the Earth's features.
  • Geo Informatics: The science and technology that develops and uses information science infrastructure to address geographical, cartographical, and geoscientific challenges.

Geo Informatics comprises various components:

  • Geographical Information System (GIS): Utilized for storing, visualizing, analyzing, and interpreting geographic data.
  • Global Positioning System (GPS): Determines the location of objects on Earth.
  • Land Information System (LIS): Integrates various tasks in traditional cadastres and land registration systems into one.

Human Geography 

Human Geography explores diverse aspects:

  • Social/Cultural Geography: Examines society's spatial dynamics and cultural contributions.
  • Historical Geography: Studies historical processes shaping spatial organization.
  • Population and Settlement Geography (Rural and Urban): Analyzes population aspects and settlement characteristics.

Political Geography

  • Political Boundaries: Studies spatial relations between political units.
  • Election Scenario: Analyzes delimitation of constituencies and political behavior.
  • Spatial Distribution of Political Processes: Explores how geographical location impacts political processes.
  • Economic Geography covers economic activities:
    • Agriculture: Involves cultivating the soil for crop production.
    • Industrial Activities: Encompasses setting up industries for goods and services.
    • Trade and Transport: Deals with merchandise sales, passenger/cargo transport, and utility services.
    • Infrastructure: Includes essential system
