Extract B The impact of rice production
Rice production contributes 12% of global methane emissions and 1.5% of all greenhouse gas emissions. Vietnam’s paddy fields, where the rice is grown, produce more carbon emissions than the country’s transportation network. Producing one kilogram of rice requires 2 500 litres of water. Rice production uses over 33% of the world’s irrigation water.
Rice growers often use an insecticide to protect the crop from insects. In the USA these insecticides contributed to a 44% decline in the bee population in 2020. On average, 90% of rice is consumed in the country in which it is grown. This limits the environmental damage caused by transporting rice abroad.
