Southern California declares unprecedented water shortage emergency

Southern California declares unprecedented water shortage emergency
Affected areas include parts of Los Angeles, Ventura and San Bernardino counties, home to around six million people

An unprecedented l'eau shortage emergency has been declared in Californie du Sud.

The affected areas include parts of Les anges, Ventura and San Bernardino counties which are home to around six million people.

Fonctionnaires made the announcement on Tuesday that, from 1st June, outdoor watering would be restricted to one day a week in areas dependent on a network of aqueducts known as the State Water Project.

The Metropolitan Water District of Southern California (MWD) has also asked residents to voluntarily cut water use across the region.

“We’re requiring these areas to cut back outdoor watering to 1 day a week, but need all #SoCal residents + businesses to save up to 30%,” the water services company tweeté.

“Due to the depth and duration of the current la sécheresse,” MWD wrote, the agency “cannot meet normal demands” in areas that depend on water from the State Water Project.

Some small exceptions are allowed such as for high-efficiency irrigation systems like drip irrigation — where water slowly drips from a porous hose instead of flowing out of a spigot — and hand-watering which is necessary to the long-term health of trees and plants.

With watering of lawns cut back to one day a week, the Los Angeles Department of Water and Power (LADWP) offre a rebate program for residents and commercial property owners to replace turf lawns with water retention features and drought-resistant plants more suited to the semi-arid climate.

California has been in a sustained drought for the past three years, ravaging the state’s water supply system. Plus de 95 per cent of the state is currently in “severe drought” conditions, according to the federal government’s drought monitor.

In the emergency declaration, MWD referenced the role of the climate crisis in driving water uncertainty.

“In addition to reduced precipitation since 2020, California’s climate is transitioning to a warmer setting in which historical relationships among temperature, precipitation, and runoff are changing,” MWD wrote.

Much of California’s water comes from snowpack in the Sierra Nevada mountains. Plus tôt ce mois-ci, LADWP averti that snowpack was less than a quarter of normal levels, and called on Californians to voluntarily cut water use.

The California Department of Water Resources has averti that the snowpack in the Sierra is expected to decline by up to 65 per cent by the end of the century.

en outre, une 2015 étude found that the climate crisis will likely increase the probability that dry years coincide with warm years in California — fuelling the perfect conditions for serious drought conditions.
