Growing Vulnerability Of The Arid Zones
To Drought And Its Impacts

Abstract
Although drought and aridity are two subtly different natural phenomena, they
are not unrelated, and when they happen simultaneously, the implications can be
disastrous.
Partly because of the natural climatic march, and partly as a consequence of
the human activities, the deserts are increasing and droughts are becoming more
persistent and recurrent. The variability and environmental changes are factors
that trigger the combination desertification-drought as a vicious circle that leads
to potential crisis conditions because of the severe impact on society and its
activities.
Given the complexity of both phenomena, and their great coverage and slow
but relentless development, it is very difficult to confront them with success, and
then neither to avoid them, but we must make, as society members, our best
efforts to formulate strategies and improve planning in order to confront its
occurrence and to mitigate its impacts.
Nevertheless, the structural (engineering) aspect is decisive for this goal, the
non-structural phase is probably of greater importance, and it is directly related
with the social participation as a group, beyond the official institutions and
government dependences; after all, we are all water users, and then we are all
indebted to contribute and to participate in the actions that allow us to overcome
these risk conditions in order to avoid expensive crises and catastrophes which
injure the humankind.
Keywords: drought, desertification, environment deterioration, water stress.
