Geography: Meaning, Definition, Aims & Purpose of Geography

• Geography, simply put, is the study of places and the relationships between people and their environments. It seeks to answer questions about where things are, why they are there, and how they got there. Have you ever wondered why some places are hot and others are cold? Or why some countries have lots of mountains, while others are flat as a pancake? Imagine it as a giant puzzle, where each piece represents a different aspect of the Earth, such as landforms, climate, people, and cultures. Geography helps us to understand the whole picture of the earth.
• The aim of geography is all about helping us become world explorers! When we learn about geography, we become like detectives, trying to solve the inter-relationship of man and nature in the context of location. One of the big aims of geography is to understand how our planet works. We learn about weather and climate, which helps us predict things like storms and sunny days. We also study the Earth’s landforms, like mountains and oceans, to learn about how they formed and why they are so important. Another aim is to explore the different cultures and ways of life around the world. Geography helps us appreciate the beauty of diversity, the fact that people in one part of the world might eat different foods, speak different languages, and celebrate different festivals than people in another part.
• One of the most important purposes is to make our world a better place. When we understand how the Earth works and how people live in different places, we can make smart decisions about things like protecting the environment and helping those in need. Geography also helps us with everyday stuff. Have you ever used a map to find your way to a new place? Well, that is geography in action! It helps us navigate and find our way around, whether it is to a friend’s house or a far-off vacation spot. Another purpose is to prepare us for the future. When we study geography, we learn about the challenges our planet faces, like climate change and pollution. By understanding these problems, we can work together to find solutions and take care of our home the Earth.

Meaning of Geography

• Since the time of Eratosthenes, the word “geography” has been in use. It initially covered all topics related to the description of Earth and its components.
• The word ‘geography’ consists of two Greek words, ‘geo’ means the Earth and ‘graphein’ means to write. The former is more significant and refers to the zone of contact of the solid, liquid, and gaseous masses that make up the planet while the latter refers to the description of these phenomena in regard to “place, localization, and distribution”.
• The term “geography” is used to describe the earth bound phenomena. There are many different phenomena taking place on the surface of the Earth; some are entirely physical phenomena while others are purely human phenomena. Some of these phenomena are mutually inclusive while others are mutually excluding. However, all of these occurrences—physical or human—are relative in the sense that they each have a unique “place of their localization” and “distribution.” The ‘core’ of geography seems to be a blend of both physical and human phenomena, taking place on the surface of the earth as mutually interrelated and interacting.
• The role people play in changing the surface of the Earth carries a similar implication. While the face of the Earth refers to that which forms the habitat or environment or space that is entirely dependent on man’s selection, changes, and modifications of various sets of earth-bound phenomena are done, play and modifying refer to particular time because people here are identified with a particular set of time with a distinct way of living that is changeable in temporal perspective (place, localization, and distribution understood). In geography, all of these earth-bound phenomena are explained correctly.

Definition of Geography

• Since ancient period to modern period, various perspectives from different parts of the world have been developed in geography. So, the definition of geography varies from one perspective to another. Therefore, in this section, you will be learning the definition of geography by different developed perspectives, i.e., ‘geography as the study of planet earth’, ‘geography as the study of location or distribution’ and ‘geography as the study of man-environment relationships’.

Geography as the Study of Planet Earth

• In the ancient history of geography, this subject was considered that branch of knowledge which deals with the planet earth, especially in the ancient Greece, in 3rd and 4th century B.C. Eratosthenes was a great Greece geographer, he explained geography as ‘the study of the earth as the home of the human beings’. So, in this part, we will understand how the geography is considered as the study of planet Earth and how the various geographers had supported this idea.
• There were a number of geographers who studied Earth and its features in the past helped in laid the foundation of the subject of geography. Some of them, like Georg Gerland (1833-1919), Ferdinand von Richthofen (1833-1905), Otto Lehmann (1855-1922), Albrecht Penck (1858-1945), and Hartshrone (1959) believed that geography is about studying the whole planet Earth. However, there is a bit of confusion about whether geography only looks at the Earth’s surface and the things we can see and feel or if it includes everything about the Earth, even things we cannot easily see.
• In 1891, a German geographer and geologist named Georg Gerland wrote an important essay called “The Position of Geography among the Natural Sciences.” He asked a big question: Does geography only study the part of the Earth that everyone knows, or does it cover the whole planet? This question was worked as a foundation for geography, and it helped establish the idea that geography is about studying the Earth as a whole system (Hartshrone, 1959). But, most geographers back then only studied things on the Earth’s surface, so geography, in practice, was mostly about the Earth as we usually think of it. The idea of studying the out part of the earth was a limited approach. In 1883, great geographer Richthofen advocated this idea in a speech at Leipzig that geographers should mainly focus on the Earth’s outer layer, but this idea did not convince everyone.
• Gerland talked about how geography and geophysics are different. He said that geography should look at the Earth like a scientific and objective thing, just one of many similar things in the universe. He thought that we focus on the Earth’s surface in geography because we cannot see what is inside the Earth. He also said that the Earth is special because it has things like a narrow temperature range and life, so it is justified to study it as its own science. Gerland accepted that science is about learning things in the universe, and the Earth is special because people live here. He explained that if we compare Earth to other similar planets, we should look at it like a celestial body in the universe, and we do need little justification to study it as its own science. Gerland concluded it by saying that we should study the Earth because it is the only planet we know where life exists.
• Indeed, throughout history, humans have consistently regarded the world they inhabit as a vital component of their existence. Consequently, we now acknowledge that Earth represents not merely a celestial body but also our exclusive abode. The term “earth surface” has taken on essential significance as it precisely delineates the physical scope of our planet’s external layer. The word “world” frequently finds usage in expressions such as “worldwide,” “world map,” and “world tour,” all of which pertain to the tangible expanse encompassing Earth’s surface. This spatial domain extends deep beneath the Earth’s surface and high into the atmosphere but excludes the Earth’s core, the moon, and other celestial bodies.
• The earth’s surface need not be precisely defined in order to understand the physical dimension of geography. The earth’s surface need not be precisely defined in order to understand the physical breadth of geography. Geographers research the surface and, if necessary, can delve deeper into a situation. There is no need to draw a line separating the outside world from the interior of the planet. Geographical research is centered on the surface of the earth, which also serves as the center for the disciplines of history, geophysics, meteorology, economics, and geology. The earth’s surface is approached differently by each science. However, academics like Richthofen frequently failed to recognize the distinction between the spatial perspective and systematic sciences addressing the same topics. In 1905, Alfred Hettner emphasized this distinction. The contributions of geographers were constrained by the specialized techniques employed in geophysics, leading to the emergence of geophysics as a distinct field linked with geology and geophysics, as observed by Wagener. There are a number of other eminent geographers who advocated ‘geography as the study of planet Earth’. Here are some of their important works:
  • William Morris Davis (1909), “Geography is the science that studies the physical and cultural features of the earth’s surface, and the spatial relationships between them”.
  • Richard Hartshorne (1939), “Geography is the study of the earth as the home of human beings”.
  • Carl Sauer (1956), “Geography is the science of the earth’s surface and the study of the relationships between people and their environment”.
  • Jean Gottmann (1973), “Geography is the study of the earth’s surface, the human use of it, and the interrelations between the two”.
  • D.W. Meinig (1975), “Geography is the science of the earth and its features, the study of human activity and its relationship with the physical environment, and the synthesis of knowledge about the earth and its inhabitants”.
  • Peter Haggett (1983), “Geography is the study of the Earth’s surface and the processes that shape it, including human activities”.
• The above discussions make it clear that the examination of the Earth’s surface holds a vital role in the field of geography. It represents the physical expanse of our planet’s outer layer, encompassing the space that extends from deep within the Earth to high into the atmosphere. Notably, it excludes the Earth’s core, moon, or other celestial bodies. Geographers are not required to precisely delineate the boundary between the world and the Earth’s interior. Instead, the Earth’s surface serves as the focal point for all scientific disciplines concerned with our planet, including history, geophysics, meteorology, economics, and geology.

Geography as the Study of Location/Distribution

• The term “location or spatial” characterizes a specific type of distribution, one that extends across a surface, as opposed to categorizing objects, as in statistical distributions. Spatial distributions encompass phenomena dispersed across a surface, typically the Earth’s surface, sharing similarities with each other. These individual elements in a spatial distribution are arranged in a manner that allows analysis and mapping of their pattern, density (the number of objects per unit area), and dispersion (how far apart the objects are from one another). Geographers can compare different spatial distributions by examining their patterns, densities, and dispersions.
• Geography focuses on understanding variations in phenomena across different places, and its significance as an academic discipline lies in its ability to elucidate the connections between various aspects within the same area—what can be termed as interrelated phenomena. The central question in geography is, “Why does this particular condition exist here?” Any phenomena with a discernible “spatial” distribution or that can be mapped hold inherent geographical interest.
• Distribution pertains to the manner in which things are dispersed or organized across a geographical area. The notion of distribution finds relevance across a wide spectrum of subjects on our planet, encompassing botanical and zoological species, as well as meteorological occurrences. Geography and geographers have demonstrated that numerous items are found in specific locations but not in others, thereby establishing geography as the science of distributions. At its core, geography, as the science of distribution, is rooted in the belief that everything on Earth holds a spatial context.
• Geographers delve into the distribution of natural elements like landforms, climate patterns, plant life, and water resources, in addition to societal elements such as population, culture, economic endeavors, and political structures. Through the examination of these patterns, geographers gain valuable insights into the reasons behind the distribution of phenomena, their interplay, and their underlying principles.
• Geography, as a science rooted in the study of distribution, finds its origins in the pioneering work of Alexander von Humboldt, a German naturalist who extensively explored South America during the early 19th century. Humboldt’s primary focus was on the spatial arrangement of plant and animal species, from which he crafted the foundational concept of the ‘geography of plants,’ eventually laying the groundwork for the field of biogeography. Since that time, geography has evolved into a multifaceted discipline encompassing various branches, including physical geography, human geography, and environmental geography. These sub-disciplines share a common emphasis on comprehending the patterns of phenomena across the Earth’s surface.
  • For instance, physical geography investigates the spatial distribution of natural elements such as climate, vegetation, and landforms. It seeks to grasp the underlying processes responsible for shaping these distributions, such as plate tectonics, weather systems, and erosion. In contrast, human geography delves into the spatial distribution of human activities, including aspects like population dynamics, migration patterns, and economic endeavors. Its aim is to uncover the social, economic, and political forces influencing these spatial patterns. Similarly, environmental geography explores the intricate interplay between humanity and the environment, examining the distribution of environmental phenomena like pollution, biodiversity, and natural resources. Its goal is to unravel the root causes and consequences of these distributions.
• Geography, as a scientific discipline focused on distribution, possesses a notable strength in its capacity to detect and scrutinize spatial arrangements and connections. Take, for instance, the fields of Cartography and Geographic Information Systems (GIS), which empower researchers to chart and evaluate spatial information across various scopes, ranging from the local level to the global stage. Such capabilities enable the identification of regions characterized by either high or low biodiversity, the tracking of trends in land use alteration, and the examination of the distribution of natural hazards like earthquakes and tsunamis.
• Geography, rooted in Humboldt’s initial concept of the interplay of elements within a geographic space, has evolved over time, marked by significant contributors and varying perspectives. During his extensive exploration of the Orinoco River, Colombia, Cuba, the West Indies, Amazon Basin, and Andes Mountains, Humboldt established that diverse factors such as precipitation, soil, vegetation, flora, fauna, and temperature exhibit variations in distribution. These variations extend to economic activities and population density. Ritter, in his book “Erdkunde,” took a teleological approach to investigate the spatial distribution of physical phenomena. Hettner, on the other hand, emphasized “distribution by place” in his studies. He delved into the significance of the Wallace Line, which demarcates the distinct flora and fauna of Australia from South-East Asia and Asia. This separation reflected varying viewpoints within the field.
• Hettner, dating back to his earliest methodological discussions in 1895, voiced objections to this concept of geography. He argued that the study of distribution should belong to systematic science rather than geography, as it pertained to the characteristics of objects and the distinctions in faunal equipment in different regions.
• This perspective consistently derives from Humboldt’s original idea that geography examines elements coexisting in an area, even in Hettner’s exploration of cultural phenomena. Despite the broad spectrum of phenomena that geographers analyze, it’s essential to recognize that focusing solely on distribution doesn’t establish a unifying foundation of interest. While geography encompasses more than the study of distributions, the question of “where” remains intrinsic to the field, particularly in systematic geography. Notably, all systematic sciences studying phenomena on Earth’s surface must address the question of “where” in their research.
• Nevertheless, geography as the exclusive study of distribution has not gained unanimous acceptance among geographers, as it’s just one facet of the discipline. Numerous scholars have contributed to the development of geography as a science of distribution, and some of the renowned figures and their works are detailed below:
  • Jones (1984), The focus of all geographical enquiries is place. This implies location on the Earth’s surface, the relationship between it and other locations, and the processes affecting changes in those relationships.
  • Smith (1977), Geography offers a broad synoptic view of spatial relationships in human affairs.
  • Yeates (1968), Geography can be regarded as a science, concerned with the rational development, and testing, of theories that explain and predict the spatial distribution and location of various characteristics on the surface of the earth.
  • Taaffe (1970), Geography is the study of spatial organization expressed as patterns and processes.
  • Schaefer (1953), Geography has to be conceived as the science concerned with the formulation of the laws governing the spatial distribution of certain features on the surface of the Earth.
  • Ackerman et al., (1965), It is the study of spatial distributions and space relations on the Earth’s surface.
  • Johann Heinrich von Thunen (1926): Von Thunen formulated an agricultural land utilization model aimed at elucidating the geographic arrangement of agricultural activities in proximity to urban centers. This model posits that the choice of crops cultivated is contingent upon their proximity to the city, taking into account factors such as perishability and transportation expenses.
  • August Losch (1930): In his renowned work on Location Theory, he elucidates the process by which businesses and various economic enterprises make decisions regarding their geographic placement, taking into account elements like transportation expenses, the availability of labor, and accessibility to markets. This theory provides insights into the geographical distribution of economic activities and the location of industrial sectors.
  • Walter Christaller (1933): Christaller’s Central Place Theory aimed to explain the arrangement of human settlements and economic practices. According to this theory, human settlements are structured in a hierarchical system, wherein larger settlements offer a wider array of intricate goods and services.
• The above discussion advocates geography’s role as the scientific study of distribution, with a primary focus on examining the patterns and spatial organization of diverse phenomena across the Earth’s surface. Geography delves into comprehending how natural and human phenomena, including landforms, climate, vegetation, population, and economic activities, are distributed. This approach operates under the premise that the distribution of these phenomena is not arbitrary; rather, it’s influenced by factors like physical and environmental processes, human actions, and historical events. By studying distribution patterns and processes, geographers can look insights into the interplay and functioning of various aspects of the Earth’s surface, enabling them to formulate theories and models for explaining and forecasting their behaviour.

Geography as the Study of Man-Environment Relationships

• Geography is often defined as the discipline focused on the interconnectedness between humans and their environment. Its primary purpose is to investigate the dynamic interactions between human societies and the natural world. Geography delves into the ways in which natural phenomena like climate, topography, and available resources mold human behaviors, and conversely, how human activities shape and impact the environment. It aims to comprehend how societies engage with, alter, and adapt to their surroundings, acknowledging that these interactions can yield both positive and negative outcomes. Through its study of the intricate human-environment connections, geography can offer valuable insights into pressing global challenges, including but not limited to climate change, environmental deterioration, and sustainable development.
• Richard Hartshorne, a distinguished geographer, made substantial contributions to the exploration of human-environment interactions. In his 1939 publication, “The Nature of Geography: A Comprehensive Examination of Contemporary Ideas in Historical Context,” he underscored the significance of comprehending the intricate interconnection between human communities and their surroundings. Hartshorne maintained that human societies were not merely passive beneficiaries of environmental forces but, rather, active agents capable of modifying and adapting their surroundings to meet their requirements.
• He acknowledged the profound impact of the environment on human societies, influencing their culture, economy, and way of life. Hartshorne’s contributions to the study of human-environment relationships maintain their impact on the field of geography in contemporary times. His emphasis on comprehending the interdependent connection between human societies and their surroundings, along with advocating for a comprehensive approach to explore this relationship, still resonates in current geographic research.
• Geography is the study of the intricate and multifaceted relationship between humans and their environment. This field of study delves into how people interact with, adapt to, and influence the natural world around them. Geographers also explore the various ways in which human societies are shaped by their surroundings, and conversely, how they shape and impact the environment. Since the post Darwinism period, various approaches have been developed in geography, i.e., determinism, possiblism and neo determinism. These approaches are offering different perspectives on the relationship between human societies and their environment. Although, these concepts differ in their perspectives on the role of the environment and human but all share a fundamental focus on the study of interaction between humans and their environment as a central theme in geographical analysis.
• Nevertheless, geography as the exclusive study of human-environment relationships has gained almost unanimous acceptance among geographers. Several scholars have contributed to the development of geography as the study of human environment relationships, and some of the renowned figures and their works are detailed below:
  • Ratzel, a great German geographer, defined geography as a synthetic study of relationship between human societies and earth’s surface.
  • Ellen C. Semple (1911), an American geographer, defined geography as the study of the changing relationship between the unresting man and the unstable earth.
  • Vidal de la Blache (1921), a French geographer, defined geography as the study of relationship between living beings and their environment.
• Thus, it is clear from the above discussion, the study of human-environment relationship is core fundamental perspective in geography. The study of humanenvironment relationships in geography explores the intricate interplay between human societies and their surroundings in the context of time and space. Geographers investigate how people influence, adapt to, and are influenced by their environment, considering factors like climate, landforms, and resources.

Aim and Purpose of Geography

• Geography is the study of our amazing planet Earth and its inhabitants. Its aim and purpose are like being a detective, but instead of solving mysteries, it helps us explore and understand the world around us. Geography’s main goal is to discover and explain all the fascinating things about our planet, from the tallest mountains to the deepest oceans and everything in between.
• First, geography helps us understand where things are located. It’s like a giant map that helps us find our way and know the different countries, cities, and landmarks. This knowledge is essential for travelers, businesses, and governments to make informed decisions. Second, geography delves into why places are the way they are. It’s like a detective story uncovering the reasons behind the diversity of landscapes, climates, and cultures. It helps us learn about the forces of nature, like earthquakes and volcanoes, as well as how people shape their environments through farming, building, and industry.
• Furthermore, geography is critical for addressing important global challenges. It guides us in studying climate change, managing resources, and understanding how our actions impact the planet. By knowing more about our world, we can make choices that protect the environment and improve the quality of life for all living creatures.
• In simple terms, geography’s aim and purpose are to explore, explain, and care for our incredible planet. It’s about knowing where things are, why they’re there, and how we can be good stewards of the Earth. So, whether you’re curious about distant lands or interested in making the world a better place, geography plays a vital role in satisfying that curiosity and creating a brighter future for all of us.
