Now in an updated edition, this pioneering and authoritative study considers the profound impact of the growing global water crunch on international peace and security as well as possible ways to mitigate the crisis. Although water is essential to sustaining life and livelihoods, geostrategist Brahma Chellaney argues that it remains the world’s most underappreciated and undervalued resource. One sobering fact is that the retail price of bottled water is already higher than the international spot price of crude oil. But unlike oil, water has no substitute, raising the specter of water becoming the next flashpoint for conflict. Water war as a concept may not mesh with the conventional construct of warfare, especially for those who plan with tanks, combat planes, and attack submarines as weapons. Yet armies don’t necessarily have to march to battle to seize or defend water resources. Water wars—in a political, diplomatic, or economic sense—are already being waged between riparian neighbors in many parts of the world, fueling cycles of bitter recrimination, exacerbating water challenges, and fostering mistrust that impedes broader regional cooperation and integration. The danger is that these water wars could escalate to armed conflict or further limit already stretched food and energy production. Writing in a direct, nontechnical, and engaging style, Brahma Chellaney draws on a wide range of research from scientific and policy fields to examine the different global linkages between water and peace. Offering a holistic picture and integrated solutions, his book has become the recognized authority on the most precious natural resource of this century and how we can secure humankind’s water future.

Water is a simple but necessary part of life. Yet much of the world's population lacks adequate clean water, either because of physical scarcity or because they are denied equitable access to water resources. Such conditions inevitably breed conflict. Water-related violence is common in many parts of the world and is generally expected to increase in the years ahead.This document is intended to assist water development practitioners, civil society peacebuilders and human rights advocates seeking to integrate water and peacebuilding in their work. The purpose is twofold: to furnish a conceptual framework for understanding problems of scarcity and equity, and to provide practical guidance and tools for action.The text distills an extensive literature on water, conflict, and cooperation produced in recent years by researchers and development practitioners. Case studies and reflections are included to keep theory grounded in reality.

As a basic human need, the provision of safe water is among the highest priorities of government and humanitarian interventions during post-conflict recovery and peacebuilding. In the aftermath of war, water, sanitation, and infrastructure play a critical role in the recovery of livelihoods and economic development. Moreover, shared waters have great potential for interstate cooperation, assisting to rebuild trust following conflict and to prevent a return to conflict. This volume draws on studies from around the world to create a framework for understanding how water resources decisions and activities can facilitate or undermine peacebuilding in a post-conflict setting.

The new 2030 Agenda for Sustainable Development includes water, sanitation, and hygiene (WASH) at its core. A dedicated Sustainable Development Goal (SDG 6) declares a commitment to "ensure availability and sustainable management of water and sanitation for all." Monitoring progress toward this goal will be challenging: direct measures of water and sanitation service quality and use are either expensive or elusive. However, reliance on household surveys poses limitations and likely overstated progress during the Millennium Development Goal period. In Innovations in WASH Impact Measures: Water and Sanitation Measurement Technologies and Practices to Inform the Sustainable Development Goals, we review the landscape of proven and emerging technologies, methods, and approaches that can support and improve on the WASH indicators proposed for SDG target 6.1, "by 2030, achieve universal and equitable access to safe and affordable drinking water for all," and target 6.2, "by 2030, achieve access to adequate and equitable sanitation and hygiene for all and end open defecation, paying special attention to the needs of women and girls and those in vulnerable situations." Although some of these technologies and methods are readily available, other promising approaches require further field evaluation and cost reductions. Emergent technologies, methods, and data-sharing platforms are increasingly aligned with program impact monitoring. Improved monitoring of water and sanitation interventions may allow more cost-effective and measurable results. In many cases, technologies and methods allow more complete and impartial data in time to allow program improvements. Of the myriad monitoring and evaluation methods, each has its own advantages and limitations. Surveys, ethnographies, and direct observation give context to more continuous and objective electronic sensor data. Overall, combined methodologies can provide a more comprehensive and instructive depiction of WASH usage and help the international development community measure our progress toward reaching the SDG WASH goals.
