Abstract :
This book provides an overview of arid and semi-arid lands conditions, their general
characteristics, and methods of management, conservation, exploitation, and reclamation. It
also focuses on how to utilize the potential of arid lands with the minimum manipulation and
alteration. Arid and semi-arid areas represent a major part of natural ecosystems not only in
Iran, but around the world, and mismanagement and inappropriate exploitation of these areas
may lead to further gradual degradation. As such, an understanding of the characteristics of
these areas is vital if they are to be conserved and reclaimed.
