Environment / Water Security
The idea of “Day Zero” has returned to global attention following UN warnings that climate change, over-extraction of groundwater and weak water governance could drive many cities, including in India, towards severe water crises.
“Day Zero” denotes the stage at which a city’s usable water supply drops below a critical limit, compelling authorities to suspend normal piped water supply and shift to tightly rationed emergency distribution. The term entered global discourse during Cape Town’s 2018 water emergency and is now used by UN agencies to describe systemic urban water failure rather than short-term drought events.
