Ecologists from the University of Cologne are Analyzing
Vegetation Stability during and after Droughts
Approximately 40 percent of the earth’s surface is covered
by drylands in which average annual precipitation is lower than evaporation.
The changes projected to unfold in these areas in the course of climate change
are alarming. Greater variations in annual and seasonal precipitation will lead
to more frequent droughts and, presumably, longer drought periods. This means
that drylands are among those areas most severely affected by climate change.
