My topic is drought

Here are the answers regarding drought:

a) Define drought.
A drought is a prolonged period of unusually low rainfall, leading to a severe shortage of water. This scarcity affects water supplies for agriculture, ecosystems, and human consumption.

b) State three causes of drought.

• Prolonged high-pressure systems that prevent rain-bearing clouds from forming or reaching an area.
• Changes in atmospheric circulation patterns, such as those associated with El Niño events, which can shift rainfall away from certain regions.
• Climate change, leading to increased temperatures that enhance evaporation and alter precipitation patterns, making dry regions drier.

c) State three impacts of drought.

• Water scarcity for drinking, sanitation, and agriculture, leading to crop failure and livestock deaths.
• Environmental degradation, including increased risk of wildfires, loss of biodiversity, and desertification.
• Economic losses due to reduced agricultural output, impacting food security and increasing food prices.

d) State three measures that can be taken to reduce the impact of drought.

• Implementing water conservation strategies, such as efficient irrigation techniques (e.g., drip irrigation) and reducing domestic water waste.
• Developing drought-resistant crops and adopting farming practices that conserve soil moisture, like no-till farming.
• Building and maintaining water infrastructure such as dams, reservoirs, and desalination plants to secure water supplies.
