Rural communities really feel the influence of drought far more than city residents. Our new analysis appears on the hyperlink between drought and suicide charges in one in every of Australia’s largest farming areas, the Murray-Darling Basin.
Drawing on month-to-month knowledge from 2006 to 2016, our findings had been alarming. We discovered, for example, that yet one more month of maximum drought within the earlier 12 months was strongly related to a 32% enhance in month-to-month suicide charges.
