Emergy quantification of economic-social-ecological losses under water supply-demand dual regulation during mega-droughts

Key Points

• Economic losses due to mega-droughts were significantly impacted by both water supply and demand regulation.
• An emergy analysis reveals a systematic approach to quantify losses across economic, social, and ecological dimensions.
• The assessment includes various ecological impacts to emphasize the interconnectedness of water availability and community resilience.
• Findings highlight the need for integrated management strategies to mitigate future mega-drought impacts on resources.
