Product Description: This powerful book shows us that we are in deep denial about the magnitude of the global environmental challenges and resource constraints facing the world. Despite growing scientific consensus on major environmental threats as well as resource depletion, societies are largely continuing with business as usual, at best attempting to tinker at the margins of the problems...read more

Product Description: This book provides a comprehensive presentation of the realization of improved rainfed agriculture yield in semi-arid and dry land areas. The incentive of watershed programs is to increase the return on investment with over 20% for 65% of the projects that are currently underperforming...read more

Product Description: Rainfed agriculture is generally overlooked by development investors, researchers and policy makers due to limited confidence in its ability to increase agricultural production and development. However, research undertaken by a team of leading scientists from global organizations demonstrates its potential in achieving food security, improving livelihoods and most importantly addressing issues of equity and poverty reduction in dryland areas - the hot spots of poverty...read more

This book exposes how water flow links nature and society through water's many parallel functions as the 'blood stream' of both the biosphere and the imbedded anthroposphere, and the resulting conflicts that arise. The authors argue that a sustainable future depends fundamentally on our ability to manage these trade-offs.They advocate an ecological approach to land/water/environmental problems and argue for viewing precipitation as the gross water resource. Distinguishing between terrestrial aquatic ecosystems they show how an ecological approach can be expressed in water-related trade-offs, incorporating criteria for long-term resilience. Based on per capita needs for an acceptable nutritional diet, the authors analyze 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, disentangling it into green and blue water scarcity components.

Product Description: If water resources are to be distributed efficiently, equitably and cost-effectively in this rapidly changing world, then it is clear that current water management practices are no longer feasible. Innovative approaches are required to meet the increasing water demands of a growing world population and economy and the needs of the ecosystems supporting them...read more (view table of contents, read Amazon.com's description)
