Water Resource Management

Since time immemorial, water is most pertinent natural resource not only for biotic and abiotic activities but it is also significant for the human survival. It is a fact that life on the earth began in water which is widely distributed substance on the mother ‘Earth. It is unique in nature and is present all parts of the world in different forms. Water plays a key role in various developmental activities i.e. economic, social, biological, chemical, physical and religious. Although, water is abundant in nature but fresh water is limited and its reserves account for only 2.53 per cent on the globe. Since the last few decades, several parts of India are already facing the serious problem of water scarcity and it is depleting very fast. The current existing scenario of water resources poses disastrous picture and it has been predicted that 21 century war will be fought on water. Therefore, the ‘Water Resource Management’ has emerged as the most dominant and core issue facing the global community today. Hence, keeping in mind its great relevance, there is an urgent need to control the depletion of water levels and to improve the quality of drinking water for the better management of water resources. Apart from the said important reasons to compile and edit this book contains several erudite research papers. Another most partinent logic and reason to bring out this book is that the year 2003 has been declared as "International Year of Fresh Water" by the U.N.O. Hence, in the light of the year of fresh water-2003, it is the great responsibility of the international scientific community to bring more and more awareness among the masses in order to conserve and manage our most valuable water resources. So, the present book entitled "Water Resource Management" is indeed important and timely. The present volume consists of 33 research papers which are purely based on various problems and major issues of water in the contemporary society. Another aim of bringing out the book is to introduce more and more latest techniques and technological methods especially rain water harvesting through the various research based articles in order to recharge ground water levels in various regions of the country where the situation is deteriorating day by day. A number of techniques including modern and traditional have also been suggested and highlighted in the current book to improve the quality and potentiality of our existing water resources.
