Climate influences nearly every part of Pakistan’s economy. Its effects are strongest where livelihoods depend directly on rainfall, river flow and seasonal temperatures.
Learning objectives
- Explain the main geographical ideas in this lesson.
- Use Pakistan-specific evidence and map terminology.
- Apply knowledge to structured and evaluation questions.
Agriculture
Temperature controls the length of the growing season, while rainfall and irrigation determine water availability. Monsoon rain can support kharif crops, and winter rain can benefit rabi crops.
Excess rain may waterlog fields, spread crop disease or delay harvesting. Drought raises irrigation demand and can reduce yields where canals or groundwater are insufficient.
Water and energy
Rainfall, snow and glacier melt contribute to river flow and reservoirs. Seasonal variation affects irrigation supply and hydel generation. Hot weather increases domestic water use and electricity demand for cooling.
Long dry periods reduce reservoir levels, while extreme rainfall can fill reservoirs rapidly and increase flood risk.
Transport, health and tourism
Fog, snow, floods, landslides and storms can interrupt roads, railways, aviation and communications. Heatwaves increase health risks, especially for outdoor workers and people without cooling or reliable water.
Climate also creates tourism seasons: cooler uplands attract summer visitors, while snow supports winter tourism where access is safe.
O Level examination guidance
- Use named sectors and explain the mechanism of impact.
- For judgement questions, consider both positive and negative climatic effects.
Review questions and answers
- How can heavy rain reduce crop output?
It may cause flooding, waterlogging, soil erosion, disease or harvesting delays. - Why can drought reduce electricity production?
Lower river and reservoir levels reduce water available for hydel generation.
