Worsening smog on the mainland is blocking natural light and could spell disaster for agriculture, scientists have warned.

He Dongxian, an associate professor with China Agricultural University's College of Water Resources and Civil Engineering, said an experiment in Beijing over recent months showed a drastic slowdown in the photosynthesis process, which allows plants to thrive.

Applied on a larger scale, such a slowdown could affect agriculture, which contributes 10 per cent to GDP. Farm output was likely to be affected by serious air pollution in winter and spring, with the prices of agricultural products expected to rise.
