The Model of Geographical Enquiry is a step-by-step method used by geographers to study any spatial problem — like floods, urban growth, crime, climate change, etc.
It has five stages:
Pattern – What is happening and where?
(Observation and Identification)
This stage identifies the spatial pattern of a phenomenon.
🔎 What we do:
Collect data
Map the distribution
Identify clusters, trends, or hotspots
📌 Example 1: Floods
Suppose we study floods in Kerala.
We map flood-affected districts.
We notice severe flooding in low-lying river basins.
👉 Pattern: Floods are concentrated near major rivers like Periyar and Pamba.
📌 Example 2: Urban Growth
Using satellite images:
We observe built-up area increasing around city centers.
👉 Pattern: Urban expansion is concentrated along highways.
Process – Why is it happening there?
(Explanation and Analysis)
Now we explain the reasons behind the pattern.
🔎 What we do:
Analyze causes
Study physical and human factors
Use statistical or GIS analysis
📌 Example 1: Floods
Why flooding near rivers?
Heavy rainfall
Encroachment of floodplains
Poor drainage
👉 Process: Human settlement in floodplains increases flood risk.
📌 Example 2: Crime
If crime is high in certain wards:
High population density
Poor street lighting
Unemployment
👉 Process: Socio-economic factors influence crime concentration.
Prediction – What might happen next?
(Projection and Modelling)
We use models and trends to forecast future conditions.
🔎 What we do:
Use time-series data
Apply GIS modelling
Use machine learning or regression
📌 Example 1: Urban Sprawl
Based on past 20 years:
Built-up area increases 3% per year
👉 Prediction: By 2035, agricultural land may reduce by 20%.
📌 Example 2: Climate
If temperature rises 0.2°C per decade:
👉 Future heatwaves may increase.
Prediction helps in planning.
Policy – What policy frameworks will guide action?
(Formulation and Implementation)
Based on findings, we design policies.
🔎 What we do:
Suggest planning rules
Recommend environmental regulations
Develop zoning laws
📌 Example 1: Flood Management
Ban construction in floodplains
Improve drainage systems
Early warning systems
📌 Example 2: Urban Planning
Promote compact city model
Protect green spaces
👉 Policy converts research into decision-making.
Practice – How effective are our actions?
(Action and Evaluation)
We check whether policies worked.
🔎 What we do:
Monitor outcomes
Evaluate success
Revise strategies
📌 Example 1: Flood Control
After new drainage system:
Flood damage reduced by 30%
👉 Practice shows improvement.
📌 Example 2: Crime Prevention
After installing street lights:
Crime rate decreases
👉 Action evaluated and improved.
Flow of Geographical Enquiry
Pattern → Process → Prediction → Policy → Practice
It is a cyclical model. After evaluation, we again observe new patterns and continue the cycle.
Simple Real-World Case Study Example
Topic: Urban Heat Island in a City
1️⃣ Pattern → Higher temperature in city center
2️⃣ Process → Concrete surfaces + less vegetation
3️⃣ Prediction → Temperature may increase further
4️⃣ Policy → Urban greening programs
5️⃣ Practice → Measure temperature after tree plantation
Why This Model is Important
Encourages scientific thinking
Links theory with real-world action
Useful in GIS, Remote Sensing, Climate studies, Crime geography
Helps in sustainable development planning
