from 5% in the 1980s to 10% in the 2000s . In North America, yields of maize and soybeans have increased , yet meteorological drought has been associated with 13% of overall yield variability. However, yield variability was not a concern where irrigation is prevalent . However, when water scarcity has reduced irrigation, yields have been negatively impacted . In Europe, yields have been affected negatively by droughts , with losses tripling between 1964 and 2015 . In West Africa, between 2000 and 2009, drought, among other altered climate conditions, led to millet and sorghum yield reductions between 10 and 20% and 5 and 15%, respectively . Between 2006 and 2016, droughts contributed to food insecurity and malnutrition in northern, eastern and southern Africa, Asia and the Pacific. In 36% of these nations-mainly in Africa-where severe droughts occurred, undernourishment increased . An attribution study showed that anthropogenic emissions increased the chances of October-December droughts over the region by 1.4-4.3 times and resulted in below-average harvests in Zambia and South Africa . Root crops, a staple in many tropics and subtropical countries, and vegetables are particularly prone to drought, leading to smaller fruits or crop failure . Livestock production has also been affected by changing seasonality, increasing frequency of drought, rising temperatures and vector-borne diseases and parasites through changes in the overall availability, as well as reduced nutritional value, of forage and feed crops  .
