Po tential Drought Research Needs
For better monitoring of droughts in China, further research is required
on linking drought monitoring models with crop yield estimation; devel-
oping models to monitor drought conditions during different phenological
phases; developing new drought models by combining TCI and VCI; and
combining drought models with remote sensing data and generating digital
simulations of drought conditions.

C onclusions
Droughts usually last long and seriously affect large agricultural areas in
China. China has paid great attention to droughts by developing drought
monitoring technology to alleviate drought impacts. The combination of
remote sensing techniques with GIS and some conventional methods are
effective ways to monitor drought in China. However, further research is
needed to improve the present setup of the drought monitoring system at
the national level.
AC KNOWLEDGMENTS The drought research presented in this chapter has been sup-
po rted by the State Science and Technology Commission of China, the Chinese
Academy of Sciences, and the Natural Science Foundation of China. The Aus-
tralia/China Joint Science and Technology Commission and Visits Program of the
CSIRO/CAS Cooperative Agreement have supported the international collabora-
tion. Contributions by Qi Yi, Feng Qiang, Li Fuqin, and Shen Guangrong are ac-
knowledged. Yu Tao, Sui Hongzhi, and Lu Yonghong provided valuable field data.
