Advances in Food-Producing Systems for Arid and Semiarid Lands: Part A contains the proceedings of a symposium on ""Advances in Food-Producing Systems for Arid and Semiarid Lands"" of the International Symposium Series held in Kuwait in April 1980. Organized into five parts, separating the first five sessions of the symposium, this book begins by discussing the needs of arid lands. It then tackles the biotechnologies that may find valuable applications in arid and semiarid lands. Furthermore, it explores the water management and environmental tolerance aspects involved in these harsh environments. The presented papers bring renewed vitality to the hope that appropriate and directed exploitation of various technologies can evolve developable industries for arid and semiarid lands.
