China, with a large population and limited arable land, is exploring ways to enhance food production and improve farmers' income, particularly in the face of urbanization and soil degradation. A study published in the American Journal of Potato Research, led by the International Potato Center (CIP), suggests that growing potatoes in rice paddies during the fallow season in southern China could be a promising solution. This practice, known as rice-potato crop rotation, not only offers economic benefits but also has positive environmental impacts by improving soil health and resource efficiency. The strategy, already adopted in Guangdong, has the potential to be expanded in other provinces like Yunnan. The CIP is collaborating with Chinese partners to develop disease-resistant potato varieties and improve production techniques to ensure the sustainability of this approach.
