Development and scope of Environmental Geography and Recent concepts in environmental Geography


Environmental Geography studies the relationship between humans and nature in a spatial (place-based) way. It combines Physical Geography (natural processes) and Human Geography (human activities).

A. Early Stage

🔹 Environmental Determinism

Concept: Nature controls human life.
Meaning: Climate, landforms, and soil decide how people live.
Example: People in deserts (like Sahara Desert) live differently from people in fertile river valleys.

🔹 Possibilism

Concept: Humans can modify nature.
Meaning: Environment gives options, but humans make choices.
Example: In dry areas like Rajasthan, people use irrigation to grow crops.

👉 In this stage, geography was mostly descriptive (explaining what exists).

B. Evolution Stage (Mid-20th Century)

Environmental problems increased due to:

  • Industrialization

  • Urbanization

  • Deforestation

  • Pollution

Geographers started studying:

  • Environmental degradation

  • Resource management

  • Human impact on ecosystems

The field became analytical and problem-solving oriented.

C. Modern Stage

Today Environmental Geography is:

  • Interdisciplinary (connected with ecology, economics, sociology, political science)

  • Data-based (uses GIS, Remote Sensing)

  • Policy-oriented (helps governments plan)

It studies global issues like:

  • Climate change

  • Biodiversity loss

  • Urban heat islands

Example: Studying rising temperature trends in cities like Bengaluru using satellite data.

Scope

The scope means what areas it covers.

Human–Environment Interaction

Concept: How humans use and modify natural systems.

Key terms:

  • Lithosphere – Land

  • Hydrosphere – Water

  • Atmosphere – Air

  • Biosphere – Living organisms

Example:
Building dams on rivers like Ganga River affects ecosystems and communities.

Ecosystem & Resource Management

Concept: Sustainable use of natural resources.

Key terms:

  • Ecosystem – Living + non-living system interacting together

  • Renewable resources – Water, forests

  • Non-renewable resources – Coal, petroleum

Example:
Forest conservation in Western Ghats to protect biodiversity.

 Environmental Hazards & Disaster Management

Concept: Study of natural and human-made disasters.

Key terms:

  • Hazard – Potential danger

  • Vulnerability – Weakness to damage

  • Mitigation – Reducing risk

  • Adaptation – Adjusting to impacts

Example:
Flood management planning in Chennai.

Environmental Degradation & Sustainability

Concept: Damage to environment and how to prevent it.

Key terms:

  • Pollution – Contamination of air, water, soil

  • Sustainable Development – Meeting present needs without harming future generations

  • Environmental Justice – Fair treatment of all people in environmental policies

Example: Reducing plastic waste in cities.


Recent Concepts in Environmental Geography

Modern Environmental Geography studies environmental problems in terms of place (spatial), time (temporal), and society (social aspects).
Today the focus is on:

Environmental Sustainability

Meaning: Using resources carefully so future generations can also use them.

Example:

  • Using solar energy instead of coal

  • Protecting forests and water

Key idea: Balance between economy + society + environment.

Environmental Justice

Meaning: Fair treatment of all people in environmental policies.

Often poor communities suffer more from pollution.

Example:
Factories located near low-income settlements causing health problems.

Goal: Equal access to clean air, water, and green spaces.

Ecological Footprint

Meaning: Measure of how much land and water a person or country needs to support their lifestyle.

If footprint is large → more resource use.

Example:
High consumption countries have larger ecological footprints.

Green Economy

Meaning: Economic development without harming the environment.

Focus on:

  • Renewable energy

  • Low carbon development

  • Recycling industries

Green Rating Project

Meaning: System that checks how environmentally friendly industries are.

In India, green rating systems evaluate pollution levels and environmental performance of industries.

Eco-mark Scheme

Meaning: Government eco-label for environmentally friendly products in India.

Products with Eco-mark cause less pollution.

Example: Soaps, detergents, paper products meeting eco standards.

Polluter Pays Principle

Meaning: The person or company causing pollution must pay for damage.

Example:
If a factory pollutes a river, it must pay compensation and clean-up costs.

Ecocide Act

Meaning: Proposed law to make large-scale environmental destruction a crime.

Example: Massive oil spills, illegal deforestation.

Anthropocene Studies

Meaning: Study of the present time where humans are the main force changing Earth.

Examples:

  • Global warming

  • Plastic pollution

  • Deforestation

Humans now influence climate and ecosystems globally.

Resilience and Vulnerability Analysis

Resilience: Ability to recover after disaster.
Vulnerability: How weak a system is to damage.

Example:

  • Coastal villages vulnerable to cyclones

  • Strong embankments increase resilience

Sustainable Resource Management

Meaning: Careful use of natural resources.

Focus on:

  • Renewable energy

  • Water conservation

  • Biodiversity protection

Geospatial Modeling and Monitoring

Meaning: Using GIS and satellite data to study environment.

Used for:

  • Tracking deforestation

  • Monitoring floods

  • Studying vegetation change

Example: Using remote sensing to detect urban heat islands.

Ecosystem Services & Biodiversity

Ecosystem services: Benefits humans get from nature.

Examples:

  • Forests give oxygen

  • Wetlands prevent floods

  • Bees help pollination

Protecting biodiversity ensures ecosystem stability.

Climate Change Mitigation & Adaptation

Mitigation: Reducing greenhouse gas emissions.
Example: Solar power, electric vehicles.

Adaptation: Adjusting to climate change.
Example: Flood-resistant houses.

Urban Environmental Management

Focus on sustainable cities:

  • Waste management

  • Green buildings

  • Urban farming

  • Public transport

Goal: Eco-friendly urban development.

Transboundary Resource Management

Some environmental problems cross borders.

Examples:

  • River pollution between countries

  • Air pollution spreading across regions

  • Climate change (global issue)

Countries must cooperate.

Supervised Classification

Image Classification in Remote Sensing Image classification in remote sensing involves categorizing pixels in an image into thematic classes to produce a map. This process is essential for land use and land cover mapping, environmental studies, and resource management. The two primary methods for classification are Supervised and Unsupervised Classification . Here's a breakdown of these methods and the key stages of image classification. 1. Types of Classification Supervised Classification In supervised classification, the analyst manually defines classes of interest (known as information classes ), such as "water," "urban," or "vegetation," and identifies training areas —sections of the image that are representative of these classes. Using these training areas, the algorithm learns the spectral characteristics of each class and applies them to classify the entire image. When to Use Supervised Classification:   - You have prior knowledge about the c...

Representation of Spatial and Temporal Relationships

In GIS, spatial and temporal relationships allow the integration of location (the "where") and time (the "when") to analyze phenomena across space and time. This combination is fundamental to studying dynamic processes such as urban growth, land-use changes, or natural disasters. Key Concepts and Terminologies Geographic Coordinates : Define the position of features on Earth using latitude, longitude, or other coordinate systems. Example: A building's location can be represented as (11.6994° N, 76.0773° E). Timestamp : Represents the temporal aspect of data, such as the date or time a phenomenon was observed. Example: A landslide occurrence recorded on 30/07/2024 . Spatial and Temporal Relationships : Describes how features relate in space and time. These relationships can be: Spatial : Topological (e.g., "intersects"), directional (e.g., "north of"), or proximity-based (e.g., "near"). Temporal : Sequential (e....

GIS: Real World and Representations - Modeling and Maps

Geographic Information Systems (GIS) serve as a bridge between the real world and digital representations of geographic phenomena. These representations allow users to store, analyze, and visualize spatial data for informed decision-making. Two key aspects of GIS in this context are modeling and maps , both of which are used to represent real-world geographic features and phenomena in a structured, analyzable format. Let's delve into these concepts, terminologies, and examples in detail. 1. Real World and Representations in GIS Concept: The real world comprises physical, tangible phenomena, such as landforms, rivers, cities, and infrastructure, as well as more abstract elements like weather patterns, population densities, and traffic flow. GIS allows us to represent these real-world phenomena digitally, enabling spatial analysis, decision-making, and visualization. The representation of the real world in GIS is achieved through various models and maps , which simplify...

History of GIS

The history of Geographic Information Systems (GIS) is rooted in early efforts to understand spatial relationships and patterns, long before the advent of digital computers. While modern GIS emerged in the mid-20th century with advances in computing, its conceptual foundations lie in cartography, spatial analysis, and thematic mapping. Early Roots of Spatial Analysis (Pre-1960s) One of the earliest documented applications of spatial analysis dates back to  1832 , when  Charles Picquet , a French geographer and cartographer, produced a cholera mortality map of Paris. In his report  Rapport sur la marche et les effets du cholĂ©ra dans Paris et le dĂ©partement de la Seine , Picquet used graduated color shading to represent cholera deaths per 1,000 inhabitants across 48 districts. This work is widely regarded as an early example of choropleth mapping and thematic cartography applied to epidemiology. A landmark moment in the history of spatial analysis occurred in  1854 , when  John Snow  inv...
