Decentralised passive water harvesting. A possible solution for a water paradigm shift in urban areas

Abstract

With approximately ten billion people predicted by 2050, a paradigm shift in global water management is required to prevent instability and growing water-related catastrophes. Water is an essential need for humankind, and the ancient practices of collecting and storing meteoric water may once again be a viable alternative.This article investigates decentralised passive water harvesting as a potential solution in urban settings. Through a qualitative discussion, this paper highlights the opportunities for a paradigm shift in the use of meteoric water using two biomimetic water harvesting concepts. Understanding this new approach's potential is critical to attaining the SDGs and addressing global urbanisation and climate change.
