Importance of Dryland Study

Water resources and ecosystem service goods are crucial to the people living in dryland regions

Dryland regions are sensitive to climate variation and human perturbations

Dryland areas in monsoon Asia are the major sources of dust aerosol

Land degradation in

semi-arid China

Desertification speed over northern China (Cai, 2005)

Before mid 1970’s: 0.15 million hec/y

mid 1970’s to 1980’s: 0.21 million hec/y

After 1990’s: 0.25 million hec/y

The difficulties for dryland study

Complicated topography and landscape.

Bad simulation in both GCM and RCM

Lack of high resolution observation data

The mechanism of water balance and water cycle are not clear

Field observing stations are running by various institutes and organizations, no data sharing or exchanging system
