Research reveals carbon footprint caused by China's irrigation system
China's groundwater irrigation system is responsible for polluting the atmosphere with more than 30 million tonnes of CO2 per year – according to research from the University of East Anglia.
Groundwater used for crop irrigation in China has grown from 10 billion cubic metres in 1950 to more than 100 billion today.
A research paper, published today in Environmental Research Letters, estimates that the pumping systems which support this immense irrigation network annually produce 33.1 MtCO2e (33.1 mega tonnes of carbon dioxide equivalent).
China is the largest greenhouse ...
