“By 2050, droughts may affect over three-quarters of the world’s population, and an estimated 4.8-5.7 billion people will live in areas that are water-scarce for at least one month each year, up from 3.6 billion today. And up to 216 million people could be forced to migrate by 2050, largely due to drought in combination with other factors including water scarcity, declining crop productivity, sea-level rise, and overpopulation.” United Nations Report

Looking at some of grass verges we have locally, it does not take much to cause serious damage, most are yellow colour due to weeks of dry weather and lack of significant rainfall.
Sure they do recover, but there is probably a point where they won't recover.
