Human Geography & Urbanisation

Population distribution = how people are spread across an area. Population density = people per km².

Pakistan's population is unevenly distributed:

• Dense: Punjab (especially central Punjab — Lahore, Faisalabad, Gujranwala belt), urban Sindh (Karachi)
• Sparse: Balochistan (44% of land area, 5% of population), northern mountains

Factors affecting distribution:

• Physical: flat fertile land (Punjab plains), water availability, mild climate
• Human: jobs, transport links, historical settlement

Urbanisation: Growing proportion of people living in cities. Pakistan is 37% urban (2024) — rising fast. Karachi (~22 million) is the 7th largest city in the world.

Causes of rural-urban migration:

• Push factors: agricultural job losses, drought, poverty, flooding, lack of services
• Pull factors: employment, education, healthcare, better infrastructure

Urban challenges in Pakistan:

• Housing: Katchi abadis (informal settlements/slums) house 50%+ of Karachi's population
• Traffic congestion: poor public transport, rapid car ownership increase
• Water supply: Karachi receives less than half its needed daily water
• Waste management: open dumping, inadequate collection
• Air pollution: industrial + vehicular emissions

Mastery Extension: Human Geography & Urbanisation

This extension turns the lesson into an active study session for Geography (AKU-GEO) on Aga Khan Board. It does not replace the current specification or a teacher's instructions. Use it after reading the main notes, and check the official syllabus linked from the subject page whenever a live rule, paper structure, or assessment detail matters.

Learning Targets

By the end of a focused revision session, you should be able to define the central idea in your own words, connect it to the lesson's supporting concepts, apply it to a new question, and explain why your method or evidence is appropriate. Use the topic description as your boundary: Population distribution, rural-urban migration and urban challenges. If an answer wanders outside that boundary, return to the command word and remove material that does not earn a mark.

Use these lesson-specific checkpoints:

• Explain this accurately without copying: Population density = people per km²; Punjab most dense.
• Explain this accurately without copying: Pakistan 37% urban; Karachi ~22 million people.
• Explain this accurately without copying: Rural-urban migration: push (poverty) + pull (jobs).
• Explain this accurately without copying: Urban challenges: housing, water, traffic, pollution.

A Reliable Answer Method

Name the process or pattern, use the map, figure, or case evidence provided, and connect causes to effects before proposing a response. Treat locations and statistics as evidence only when they come from the question or a current source. Distinguish a local example from a universal rule.

Before writing, spend a few seconds planning. Circle or note the command word, identify the exact knowledge being tested, and decide what evidence, working, example, or quotation is needed. During the answer, make every line do a job. At the end, reread the question and verify that your conclusion follows from the steps you actually showed.

Apply the Pakistan Context Carefully

The lesson's local case is Karachi's Katchi Abadis — Urbanisation and Inequality. Karachi's Orangi Town is the largest informal settlement in Asia — home to over 2.4 million people. Residents built their own water pipes, drainage, and schools (Orangi Pilot Project — a famous development case study). AKU Geography papers regularly use Karachi as an urbanisation case study, asking about push-pull migration factors and challenges of rapid urban growth Use this example to make an abstract idea memorable, but do not force it into an exam response when the question supplies a different context. A good application names the relevant feature, explains the connection, and also states where the comparison stops.

Try this three-part application drill:

1. Summarise the local example in one accurate sentence.
2. Identify which key point it demonstrates and quote or calculate the evidence available in the lesson.
3. Change one condition in the scenario and explain how the result, interpretation, or decision might change.

Guided Retrieval and Practice

Sketch and label the process, add the Pakistan example as a separate case box, and practise one compare, one explain, and one evaluate response. Work without notes first; retrieval is the test. Mark the attempt only after finishing, using the lesson and the explanation rather than memory or confidence.

1. Question lens: Which Pakistani province has the lowest population density

   After answering, justify the choice using this check: Balochistan covers 44% of Pakistan's land but has only about 5% of the population — extremely low density due to arid terrain

1. Question lens: A push factor in rural-urban migration is:

   After answering, justify the choice using this check: Push factors drive people away from rural areas — drought, job losses, flooding. Pull factors attract to cities

1. Question lens: Urbanisation rate increases when:

   After answering, justify the choice using this check: Urbanisation = growing proportion living in cities. Driven by people moving from rural areas + natural population growth within cities

For every missed question, keep an error log with four fields: what I chose, why it was tempting, the rule or evidence I missed, and the cue I will notice next time. This turns a wrong answer into a reusable revision asset instead of a score you immediately forget.

Seven-Day Revision Loop

• Day 1 — Understand: read the lesson and reduce each section to one sentence.
• Day 2 — Recall: reproduce the key points with the page closed.
• Day 3 — Apply: complete the local-context drill and one unfamiliar example.
• Day 4 — Practise: answer the inline quiz, showing or saying your reasoning before selecting an option.
• Day 5 — Repair: revisit only the weak steps recorded in your error log.
• Day 6 — Mix: combine this topic with an earlier topic from the same subject so that you must choose the correct method.
• Day 7 — Check: complete a timed response, self-mark conservatively, and plan the next review date.

You are ready to move on when you can explain the topic without the notes, answer the lesson-specific checks with reasons, apply the idea to a fresh context, and identify one common mistake before making it. If one of those checks fails, repeat the relevant stage rather than rereading everything.
