Climate change as a driver of food insecurity in the 2007 Lesotho-South Africa drought

Abstract Climate-induced food production shocks, like droughts, can cause food shortages and price spikes, leading to food insecurity. In 2007, a synchronous crop failure in Lesotho and South Africa—Lesotho’s sole trading partner—led to a period of severe food insecurity in Lesotho. Here, we use ext...
