Conclusions
D
rought is a significant problem for Portugal. Droughts have become more
fr
equent and severe since the 1980s, seriously affecting agricultural produc-
tio
n. A drought early warning system is being developed. In this regard, var-
io
us drought indices and satellite data are being studied. Such a system will
he
lp better manage droughts and alleviate economic and social impacts.
C
ooperation between governmental and associate institutions is a must for
su
ch a system to succeed and help concerned farmers and industries.
