Abstract(s)
Portugal has a Mediterranean climate characterized by hot, dry summers. According to data
from the Portuguese IM (Instituto de Meteorologia), over the last decade, summer temperatures
have tended to be higher, with a greater incidence of heat waves, temperatures above 40 oC,
and periods of consecutive warm nights (daily minimum air temperature above 20oC).
During the summer, very high temperatures and heat waves are becoming increasingly common
in Portugal. The summers of 2003, 2004, 2005 and 2006 were among the hottest ever recorded.
These frequently hot climatic conditions can cause problems in intensive animal production, or
even to livestock in extensive systems. In most cases, livestock buildings are not designed for
animal production under high temperatures and most of them do not have environmental control
equipment suitable for controlling the indoor climate under such conditions.
An analysis of climatic data revealed the existence of two regions (Alentejo and Trás-os-Montes)
where high temperatures are more usual and summers tend to be hot. In these two regions,
livestock numbers are high and play a major role in the regional economy. The occurrence of
hot climate conditions was identified and its impact on the environmental conditions in animal
housing discussed
