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.
