FAQs on Understanding Droughts Video Lecture - Geography for UPSC CSE
| 1. What is a drought? |  |
Ans. A drought is a prolonged period of abnormally low rainfall, resulting in a shortage of water supply for plants, animals, and human activities. It is characterized by a significant reduction in precipitation over a specific region or area for an extended period of time.
| 2. What are the causes of droughts? | |
Ans. Droughts can be caused by various factors, including natural climate patterns such as El Niño and La Niña, which affect the distribution of rainfall. Other causes include high temperatures, changes in atmospheric pressure systems, and human activities such as excessive water consumption, deforestation, and overuse of groundwater.
| 3. How do droughts impact agriculture? | |
Ans. Droughts have a severe impact on agriculture as they result in a lack of water for irrigation, leading to crop failure and reduced agricultural productivity. This can result in food shortages, higher food prices, and economic losses for farmers. Droughts can also lead to the loss of livestock and damage to natural ecosystems.
| 4. Are droughts becoming more frequent and severe? | |
Ans. There is evidence to suggest that droughts are becoming more frequent and severe in certain regions due to climate change. Rising global temperatures can lead to increased evaporation rates, drying up water sources and exacerbating drought conditions. However, it is important to note that the severity and frequency of droughts can vary from region to region.
| 5. How can we mitigate the impacts of droughts? | |
Ans. Mitigating the impacts of droughts involves a combination of strategies, including water conservation, efficient irrigation practices, and sustainable management of water resources. Implementing drought-resistant crops and improving early warning systems can also help communities prepare for and respond to drought conditions. Additionally, promoting climate change mitigation and adaptation measures can contribute to reducing the likelihood and severity of droughts in the long term.
