Abstract

The city of Cape Town suffered a severe water crisis in 2018. At the peak of the drought in South Africa's Western Cape, a randomized control trial at 105 schools investigated the impact of two behavioral interventions to encourage responsible water usage: detailed water usage data feedback from smart meters, and an interschool competition. Interventions reduced water usage in these schools by 15–26%. There was no significant difference between the information feedback and the combination of information feedback and competition. This example from Cape Town demonstrates the effectiveness of combining smart technologies with nudges. It provides a model of water conservation interventions for sustainable cities.

通过使用智能计量和行为改变来节约开普敦学校的用水

2018年，开普敦市遭遇了严重的水危机。在南非西开普省干旱最严重的时候，一项针对105所学校的随机对照试验调查了两种行为干预措施的影响，以鼓励负责任的用水:来自智能电表的详细用水数据反馈和校际竞争。干预措施使这些学校的用水量减少了15-26%。信息反馈与信息反馈与竞争相结合的结果无显著差异。这个来自开普敦的例子证明了将智能技术与推动相结合的有效性。它为可持续城市的节水干预提供了一个模型。

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.
