Dust storm as an environmental problem in north China.

Dust storms in north China, which are associated with land deterioration from increasing human pressures, have intensified over the past decades. Although synoptic meteorological conditions and sedimental environments dictate the occurrence of dust storms, their increase in frequency in north China due to human activities can be expected. Sand stabilization and control projects may be compromised by the pursuit of short-term economic returns and lack of systematic and integrated understanding of land degradation. Two actions are recommended as positive responses to escalating dust storms in north China. A policy of long-term ecologically sustainable development strategies is needed as well as a scientific research initiative combining biophysical and socioeconomic aspects.
