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 2050 and identify potential sources. Drawing on small-scale experiences in Africa and Asia, they also cover the vulnerability of the semi-arid tropics through a simplified model of green and blue water scarcity components.

Industry Reviews

"Falkenmark (Stockhold International Water Inst.) and Rockstrom (UNESCO-IHE Inst. For Water Education, The Netherlands) have written an excellent book that bridges hydrology and ecology. The authors advocate an ecohydrological approach to water management based on the principle that rainfall, not runoff, constitutes the basic freshwater resource. The strong links between soil, water, plants, and the atmosphere are evident when rainfall is partitioned 'green' water vapor flow from evaporation and transpiration and 'blue' liquid water flow in rivers, lakes, and aquifers. With proper management, green water needs for producing food and maintaining natural biomass growth may be reduced, thereby securing more blue water for sustaining ecosystems and human activities. This book focuses on four areas: water supply to humans and industry, water in the plant production process, water as an active participant in generating environmental impacts from human activities, and water's implication in times of drought. The fundamental issue addressed by the authors is the socioecohydrological balance between the beneficial use of water for goods and services (e.g., food, fiber, energy and the protection and sustenance of essential ecosystem functions. This well-written, informative book makes a valuable contribution to the water management literature. Summing Up: Highly recommended. All levels, especially ecologists and hydrologists."--M. J. Zwolinski, University of Arizona in CHOICE
