US-China soy trade war could destroy 13 million hectares of rainforest

Study suggests Brazil likely to rush to fill China's sudden soy shortfall by boosting farming

The Amazon rainforest could be the greatest casualty of the trade war between the United States and China, warns a new study showing how deforestation pressures have surged as a result of the geopolitical jolt in global soy markets.

Up to 13m hectares of forest and savannah - an area the size of Greece - would have to be cleared if Brazil and other exporters were to fill the huge shortfall in soy supply to China that has suddenly appeared since Donald Trump imposed hefty tariffs, according to the paper published in Nature.

US exports of the commodity, primarily used to feed livestock, to China plummeted by 50% last year, which the authors say is an unusually sharp level of decline between two trading partners outside wartime.
