Natural hazards: causes and effects. Lesson 7-Drought.

Area of Science:

• Environmental Science
• Climatology
• Agricultural Science

Background:

• Drought is a significant natural disaster with increasing global impact.
• It affects various sectors including agriculture, livestock, industry, and human populations.
• Droughts can occur even in regions with historically adequate rainfall.

Purpose of the Study:

• To define and characterize drought as a multifaceted environmental and societal challenge.
• To highlight the broad implications of water scarcity beyond arid regions.
• To underscore the human impact of drought, emphasizing the need for adequate water resources.

Main Methods:

• Literature review and synthesis of existing definitions and impacts of drought.
• Analysis of drought's characteristics, including climatic dryness and its effects on soil moisture.
• Inclusion of socio-relevant definitions to capture the human dimension of water scarcity.

Main Results:

• Drought is defined as a severe climatic dryness impacting essential resources.
• It is identified as the natural disaster causing the most annual human victims.
• Causes of drought are diverse, including supply issues, contamination, inadequate infrastructure, and increased demand.

Conclusions:

• Drought poses a severe threat to human well-being and ecosystems.
• Effective water management strategies are crucial to mitigate drought's devastating effects.
• Understanding drought's multifaceted nature is key to addressing its societal and environmental consequences.
