Downstream water users in China’s capital city, Beijing, have been paying upstream agricultural users to change their crops from rice to corn in an effort to reduce the amount of water used and improve water quality in the city’s only surface water source, the Miyun reservoir. This payment for ecosystem services project, the Paddy Land-to-Dry Land (PLDL) program, has had an overall positive effect on both water quality and quantity, according to a new study published last week in the Proceedings of the National Academy of Sciences.
