Drought Contrast Lab

When the water runs short 🏜️

A **drought** is a long period when an area gets much **less water than normal** - usually from a spell of below-average rainfall, sometimes lasting months or years. Droughts do not hit everywhere equally. The same dry spell can be a minor inconvenience in one country and a disaster in another. This module covers what **causes** a drought and why some places are more **vulnerable** - then the skill the exam rewards most: **comparing** how a richer and a poorer country cope.

Three kinds of cause 🗂️

Geographers sort the causes of drought into three types. Keep them separate - the exam likes you to name which kind you mean.

What deepens a drought? ✅

Select the TWO human factors that can turn a dry spell into a serious water shortage.

• Taking too much water from rivers and groundwater for farming and cities
• A growing population and industry demanding ever more water
• Planting more trees across a river catchment
• Building extra reservoirs to store winter rain

How a drought unfolds 🪜

Why some places suffer more 🎯

The same shortfall of rain does not hit two places the same way. A location is **more vulnerable** to drought when: - it already has a **hot, dry climate** with little spare water;\n- many people depend on **rain-fed farming** for food and income;\n- there is little **water-storage infrastructure** (reservoirs, pipes, treatment);\n- demand is **high and rising** from a growing population.\n\nNotice how many of these come down to **money and infrastructure** - which is exactly why development level matters so much.

Match each cause to an example 🔗

Which kind of cause? ❓

After a dry winter, a region's main reservoir falls to a quarter of its usual level and rivers slow to a trickle. This is best described as which kind of drought cause?

• Hydrological - the shortfall has reached the water stores
• Meteorological - it is only about the rainfall
• Human - people caused it directly
• None - low reservoirs are not linked to drought

The same drought, two very different stories ⚖️

Here is the heart of the exam question. Give the SAME drought to a higher-income and a lower-income country and the impacts and responses diverge - and almost every difference traces back to wealth.

Sort each impact 🧩

Which response needs the most money? 💧

A country wants to guarantee fresh water even during a long drought. Which response depends most on wealth and infrastructure - and so is far easier for a richer country?

• Building desalination plants to turn seawater into drinking water
• Asking residents to save water and banning hosepipes
• Encouraging people to take shorter showers
• Waiting and hoping the rain returns soon

The summary 📝

A drought begins as a _____ shortfall of rainfall, which becomes a _____ drought when rivers and reservoirs run low. People can make it worse through over-abstraction and rising _____. The same drought hits a lower-income country harder because so many depend on _____ farming, while a higher-income country can afford expensive responses such as _____.

The grade-9 technique 🌟

Here is what turns a good drought answer into a top one. A weaker answer describes country A in full, then country B in full, and leaves the examiner to spot the differences. A grade-9 answer **compares directly**: "*Whereas* the richer country funded desalination, the poorer country *relied on* international aid." Every sentence sets the two side by side and ties the difference back to **wealth, infrastructure and capacity**. Same drought, opposite outcomes - and your job is to explain exactly why.
