An international team of scientists has warned that the global wheat harvest could decrease by 13% by 2050 due to the spread of the grain fungus Magnaporthe oryzae. First discovered in 1985 in Brazil, the fungus has since spread to other Latin American countries, Bangladesh, and Zambia. It is also spreading to previously unaffected regions including India, eastern Africa, Australia, the southeastern USA, Uruguay, and Central America. The most affected regions will be South America, Asia, and southern Africa, with a potential 75% crop death in South America and Africa. To mitigate this, farmers may need to switch to more resistant crops or breed more resistant wheat varieties.
