Water is a precious resource that is currently in need of long-term planning for storage and judicious use for the survival of mankind. Excessive exploitation of water without any systematic conservation programme can lead to depletion of the resource beyond recovery, as is being currently experienced in the arid regions. Western part of Rajasthan state is the most problematic area within the hot arid zone. The average annual rainfall her is 318 mm, as compared to 531 mm in Rajasthan state. Due to low and erratic rainfall, replenishment of exploited water is also very poor. During the twentieth century, different parts of western Rajasthan experienced agricultural drought once in three years to every alternate year. The book contains valuable information on arid horticulture systems. This book will be useful for the scientists, teachers, researchers, students, policy makers and also fro the arid crop based industry personnel.
