Drought
Imagine turning on the tap, but only a few drops of water come out. The grass in your garden turns yellow and dry, and small rivers or lakes may even dry up. This is drought — a long period with little or no rainfall.
Drought does not strike suddenly like a storm. It happens slowly, month after month. When there is not enough rain and the weather is extremely hot, water in rivers and soil dries up quickly. Climate change, cutting down too many trees, and using too much water in daily life also make drought more serious.
Scientists know how bad drought is by monitoring rainfall, river and well water levels, and soil moisture. Sometimes droughts are mild, so people still have enough water for daily life. But when severe, rivers dry up, wells run dry, and clean water becomes hard to find.
Drought affects everyone. Plants and crops die, leading to food shortages and rising prices. People and animals may not have enough clean water to drink. Dry land and trees can also easily catch fire, which destroy natural homes for animals.
Drought is a servere natural disaster, yet understanding its causes and effects can help us prepare for and protect our water resources for the future.
