This book discuss the central dimensions for water problem in Yemen, Which is a complex three-dimensioned problem reflected through: First: the depletion of the underground water without a recharge commensurate with the rate of water consumption; Second: an acute shortage of water supplies to provide population communities, particularly the cities, with the water amount they need; and Finally: the rapidly decreasing drinking water needed for a large number of people. Therefore, this significant book addresses the problem from different aspects. It is divided into eight chapters, where the problem is deeply considered from different angles and with a futuristic view. The chapters present an accurate and scientific account based on in-depth field studies that have addressed the water problem, as well as the consequences and future impacts in both the short and long terms if no serious and efficient actions are taken. Then, they provide various solutions and alternatives that are feasible and suitable for the situation in Yemen. Finally, the last part of the book suggests strategies, policies and mechanisms for managing and developing water resources in Yemen.
