Module 8 droughts Flashcards
What is drought?
A natural phenomenon characterized by an extended period of abnormally low precipitation, resulting in water shortages that can significantly impact ecosystems, agriculture, and communities.
What initiates the onset of drought?
Changes in weather patterns, such as persistent high-pressure systems that block rain-bearing clouds.
What is the rain shadow effect?
A phenomenon where geographical features, such as mountain ranges, block moist air masses, reducing rainfall on the leeward side.
What are some impacts of drought on agriculture?
Devastated crops, reduced yields, crop failure, and economic losses.
How does drought affect livestock?
It leads to water scarcity and can result in food shortages.
What socio-economic challenges can arise from drought?
Food insecurity, migration, and economic downturns in agriculture-dependent regions.
What are the ecological impacts of drought?
Water stress in natural ecosystems, habitat loss, biodiversity decline, and increased risk of wildfires.
How do drought conditions influence wildfires?
Drought leads to water scarcity, which can spur wildfires in dry areas.
What resources are affected by drought?
Surface water and groundwater availability, impacting drinking water, irrigation, and industrial use.
True or False: Drought can lead to conflicts over water rights.
True.
What are some strategies to mitigate the impact of drought?
Using water responsibly, cultivating drought-resistant crops, implementing sustainable land management, developing water harvesting techniques, and investing in monitoring technologies.
Fill in the blank: Individuals and communities can contribute to addressing drought by promoting _______.
[water-saving technologies].
What is one way to enhance ecosystem resilience to drought?
Implement sustainable land management practices to reduce soil erosion and improve water retention.
What is the purpose of monitoring technologies and early warning systems in drought management?
To provide timely information on emerging drought conditions, enabling proactive responses.
What is essential to manage drought conditions effectively?
Understanding the causes, impacts, and measures to conserve water.
What can be developed to capture and store water during periods of rainfall?
Water harvesting techniques, such as rainwater harvesting and small-scale reservoirs.
