Abstract

Water withdrawal for public/private suppliers and public services (defined as public water use) and for irrigation (defined as irrigation water use) are essential components of agricultural water management as well as of the planning and management of domestic, commercial, and municipal water supplies. A significant fraction of the public and irrigation water use is consumptive (defined as the part of water withdrawn that is consumed) in nature, and it is primarily freshwater. Global climate change and variability have substantially impacted the large-scale drivers of freshwater resources across the globe, which include, for example, precipitation, temperature, evapotranspiration, soil moisture, and hydrologic extremes. Global environmental change has also influenced several local-scale freshwater availability drivers, such as water quality, municipal policies, and water taxation. Overall, the changes in freshwater resources have potentially stressed irrigation and public water use. Population growth has altered the supply–demand fronts of water balance, resulting in increased water supply stresses. Researchers have considered several soft-and hard-path solutions to augment the deficit in the supply–demand fronts; however, each solution has its own pros and cons. The ongoing COVID-19 pandemic has exacerbated the already existing critical issues related to sustainable future water use. New challenges have emerged, requiring both short-and long-term solutions. Hence, it is essential to understand the current public and irrigation water use changes resulting from the pandemic. An appropriate estimate of the future changes in water use would help develop/upgrade new/current water resource systems that can mitigate risks and show increased resiliency against global climate and environmental changes and unprecedented events like the COVID-19 pandemic. In this opinion chapter, we discuss some examples of the regional/local changes in water use during the ongoing pandemic and our increased preparedness or the lack of it. Additionally, the chapter focuses on the future risks and resilience of water resource systems to meet the future demands of water use as well as to face unprecedented events such as the COVID-19 pandemic. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer 2022.
