Suketu Mehta (Gujarati Indian American writer, an associate professor of journalism at New York University, and author of “Maximum City: Bombay Lost and Found” and “This Land is Our Land. An Immigrant’s Manifesto”) (2019): “But migration driven by climate change isn’t something that’s safely in the future; it’s been dramatically increasing in the recent past. Since 1992, 4.2 billion people have been affected by droughts, floods and storms. Today, 1.8 billion people are suffering the effects of drought, land degradation, and desertification… Migrants come to work because they can’t work at home. Heat waves took almost a million people out of the global workplace in 2016, half of them in India alone. They come to eat because they can’t eat at home. For every degree Celsius increase in temperature, wheat yields have been falling by 6 percent and rice yields by 3 percent. 1.5 degrees, corn yields shrink by 10 percent” (pages 102-103, Suketu Mehta , “This Land Is Our Land. An Immigrant’s Manifesto ”, Farrar, Straus and Giroux, New York, 2019).
