Soil erosion a threat to China

A national survey of China in 2004 found that soil erosion has impacted upon 37% of the total area of China. In response to this increasing threat a new, wide-ranging investigation involving more than 200 scientists and policy-makers has been launched (5th July 2005). The aim will be to determine the seriousness of the problem, raise public awareness and develop key strategies to curb erosion.

Bluebird Canyon Landslide

On 1st June 2005, Bluebird Canyon in California experienced a landslide. It would appear that exceptionally heavy rainfall during the winter period (esp December to February) was the underlying cause of the instability. It is thought that gradual movement of this water into and through the ground caused an unusual increase in groundwater level, subsequently leading to instability. There is concern that the area upslope of the current landslide may enlarge in the coming weeks and months.
