This article explores its role in water conservation and how it fits into broader drought mitigation strategies.<\/span><\/i>\u00a0<\/span><\/p>\n As <\/span>California, Arizona, and Texas<\/span><\/b> grapple with extreme droughts, an age-old practice is gaining renewed attention: <\/span>rainwater harvesting<\/span><\/b>.
