Abstract
In the 2016–2018 drought, Cape Town almost ran out of municipal water. Tariff increases, restrictions and campaigns brought big reductions in water use during the dry spring and summer months: 14.3% in September 2017, when non-compliant households were threatened with a water usage restriction meter; 17.2% in October, when a disaster plan threatened residents with collecting water daily at 200 points across the City; and 20.1–24.3%, when “Day Zero” appeared unavoidable, water pressure was reduced, usage was restricted to 50 L per person per day and exponential tariff hikes were introduced. Transparent information about the severity of the crisis and shifting the responsibility for crisis avoidance to residents amplified water savings at the height of the drought.
期刊介绍：
Water Resources and Economics is one of a series of specialist titles launched by the highly-regarded Water Research. For the purpose of sustainable water resources management, understanding the multiple connections and feedback mechanisms between water resources and the economy is crucial. Water Resources and Economics addresses the financial and economic dimensions associated with water resources use and governance, across different economic sectors like agriculture, energy, industry, shipping, recreation and urban and rural water supply, at local, regional and transboundary scale.
Topics of interest include (but are not restricted to) the economics of:
Aquatic ecosystem services-
Blue economy-
Climate change and flood risk management-
Climate smart agriculture-
Coastal management-
Droughts and water scarcity-
Environmental flows-
Eutrophication-
Food, water, energy nexus-
Groundwater management-
Hydropower generation-
Hydrological risks and uncertainties-
Marine resources-
Nature-based solutions-
Resource recovery-
River restoration-
Storm water harvesting-
Transboundary water allocation-
Urban water management-
Wastewater treatment-
Watershed management-
Water health risks-
Water pollution-
Water quality management-
Water security-
Water stress-
Water technology innovation.
