California Governor Gavin Newsom is seeking $1.4 billion dollars from lawmakers to tackle the escalating homelessness crisis in his state and plans to use the money to open shelters, pay rent and provide health care, his office said.

The Democratic governor, who plans to formally submit his proposal on Friday, this week also signed an executive order directing agencies to identify state-owned land that can be used as temporary shelters for the homeless.

"Homelessness is a national crisis, one that's spreading across the West Coast and cities across the country," Newsom said in a statement. "The state of California is treating it as a real emergency - because it is one."

His executive order also calls for the supply of 100 camp trailers for temporary housing and to deliver health services, as well as the creation of a crisis response team to address street homelessness.

His proposals come amid an escalating homelessness crisis in California, despite hundreds of millions of dollars pledged in recent years to address the problem.

According to a report published this week by the US Department of Housing and Urban Development, nearly 568,000 people experienced homelessness on a single night last year across America, with more than a quarter of them - about 151,000 - living in California.

The report said homelessness in California increased by 21,306, or 16.4 percent, between 2018 and 2019, which is more than the total national increase of every other state combined.

One the key reasons for the mounting numbers is a severe shortage of affordable housing and gentrification sweeping many California cities.

Experts say that a person earning minimum wage currently would need to work 80 hours a week to afford a one-bedroom apartment in Los Angeles. The cost in San Francisco is even higher.

Newsom hopes his 2020-2021 budget proposal to tackle homelessness will help stem the crisis in the country's most populous state, which boasts the fifth-largest economy in the world.
