Drought
Drought EWSs are the least developed systems due to droughts' complex processes
and environmental and social impacts. The review of existing drought EWSs shows
that only a few such systems exist worldwide.
Founded in 1985, the Famine Early Warning Systems Network (FEWS NET)
monitors emerging food security issues in several countries in Africa, Central
America, the Caribbean, Central Asia, and the Middle East.
The US Drought Monitor (Svoboda et al.
2002
) integrates multiple drought indi-
cators with fi eld information and expert input and provides current drought condi-
tions for the United States through an interactive map, current drought impacts'
reports, as well as weekly forecasts (Fig.
6.6
).
The Beijing Climate Center (BCC) of the China Meteorological Administration
(CMA) monitors droughts for China and provides daily drought reports and a map
on current drought conditions. The European Commission Joint Research Center
(EC-JRC) provides public access to daily soil moisture maps of Europe, daily soil
moisture anomaly maps of Europe, and daily maps of the forecasted top soil moisture
development in Europe (7-day trend).
