From BBC: “The dust storms, which can entirely envelop Beijing, have become an all too frequent event – and China’s neighbours, Korea and Japan, have also complained about the oppressive billows of dust.
They are due to overgrazing and over-ploughing in Inner Mongolia, in the north of China, loosening the topsoil, which is then blown away by strong winds.
It has prompted the controversial policy of ecological migration – shifting thousands of families off degraded lands and into small, newly-constructed villages. ”
