India's decision to ban wheat exports is set to worsen the global food crisis, according to professor William Moseley of McAlester College. The ban, which follows a surge in global wheat prices, has already driven wheat prices in Europe to a record high. While India is not a major wheat exporter, its plans to increase exports have been hampered by a heat wave. Moseley emphasizes the need for a shift towards a more sustainable and less energy-dependent food system, highlighting the benefits of diversifying grains and adopting an agroecological approach. The ongoing conflict in Ukraine, a key grain producer, further threatens to drive up food prices and increase worldwide hunger.
