What caused the East African drought?

The drought is tied to the strong La Niña conditions that prevailed in late 2010 and early 2011. La Niña shifts ocean temperatures and air pressure over the Pacific Ocean, and its effects ripple through weather patterns around the world. In East Africa, La Niña causes drought.

What are the causes and effects of droughts?

The soil starts drying out and plants die. When this pattern continues for several weeks, months or years, the flow of streams and rivers decreases and water levels in lakes, reservoirs and wells fall. Eventually, the unusual dry weather causes water supply issues, and the dry period becomes a drought.

What are the main causes of drought?

A lack of water in stores such as rivers, lakes, reservoirs and aquifers (water stored underground naturally) can lead to drought. Areas that rely on rainfall and surface water are more likely to experience drought. Surface water quickly evaporates in warm, dry conditions leading to an increased risk of drought.

What are the long-term effects of drought?

If drought becomes prolonged, the branches of woody plants will begin to die back, and plants can die entirely if their ability to absorb water from the environment is damaged (UMass Amherst). In long-term drought, native plants may die back, allowing for the intrusion of invasive plant species.

How can we prevent droughts?

Being mindful of the amount of water you use each day can be a powerful way to prevent droughts. Turning off the faucet while you brush your teeth, watering your garden early in the morning so less water evaporates, and installing low-flow plumbing fixtures all are good ways to prevent wasted water.
