Balancing Water for Humans and Nature‎,‎ authored by two of the world‎'‎s leading experts on water management‎,‎ examines water flows ‎- the ‎'‎blood stream‎'‎ of both nature and society ‎- in terms of the crucial links‎,‎ balances‎,‎ conflicts and trade‎-offs between human and environmental needs‎.‎ The authors argue that a sustainable future depends fundamentally on our ability to manage these trade‎-offs and encourage long‎-term resilience‎.‎ They advocate an ecohydrological approach to land/water/environmental problems and advance a strong‎,‎ reasoned argument for viewing precipitation as the gross fresh water resource‎,‎ ultimately responsible for sustaining all terrestrial and aquatic ecosystem services‎.‎ This book makes the most coherent and holistic argument to date for a new ecological approach to understanding and managing water resources for the benefit of all‎.‎ Basing their analysis on per capita needs for an acceptable nutritional diet‎,‎ the authors analyse predictions of the amounts of water needed for global food production by 205‎.‎‎.‎‎.‎
