Sand and dust storms: underrated natural hazards

Area of Science:

• Environmental Science
• Natural Hazards Research
• Socioeconomic Impact Studies

Background:

• Sand and dust storms (SDS) are wind erosion phenomena prevalent in drylands but with global reach due to long-distance dust transport.
• Despite frequent occurrence and significant societal impacts, SDS are underrepresented in disaster literature.
• SDS effects span economic, physical, and social spheres, affecting critical sectors like agriculture and health.

Purpose of the Study:

• To examine the multifaceted ramifications of sand and dust storms (SDS) within a hazard context.
• To consolidate understanding of SDS impacts across economic, physical, and social dimensions.
• To highlight the need for more consistent data collection and analysis in SDS impact assessments.

Main Methods:

• Review and synthesis of existing literature on SDS impacts.
• Analysis of SDS ramifications across key societal sectors including agriculture, health, transport, utilities, households, and industry.
• Examination of economic consequences, acknowledging inconsistencies in current assessment methodologies.

Main Results:

• SDS pose significant risks to agriculture, health, and various economic sectors.
• While SDS may not cause extensive infrastructure damage like other disasters, their cumulative societal effects are substantial due to high frequency.
• Existing economic assessments of SDS suffer from inconsistent data and analytical approaches.

Conclusions:

• Sand and dust storms (SDS) represent a significant, yet often overlooked, natural hazard with widespread societal consequences.
• Further research with standardized methodologies is crucial for accurately quantifying and mitigating SDS impacts.
• Integrating SDS into disaster risk frameworks is essential for effective societal preparedness and response.
