nutrition-related health  and exposure to stressors such as drought, floods  and extreme heat . One study  found that the risk of simultaneous crop failure in maize is estimated to increase from 6% to 40% at 1.5℃ relative to the historical baseline climate. In particular, further research on projected regional yield declines of wheat and maize between 1.5℃ and 2ºC, especially in Africa, has accrued Asseng et al. , including in Ethiopia  with associated economic effects . Optimum maize production areas in East Asia are projected to reduce in area by 38% for global warming of 1.5-2.0℃ . A study of Jamaica also estimated that warming of less than 1.5℃ will have an overall negative impact on crop suitability and a general reduction in the range of crops, but above 1.5ºC, irreversible changes to Jamaica's agriculture sector were projected .
