Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems-consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances-carry drinking water from a centralized treatment plant or well supplies to consumers' taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.

Research carried out by the World Bank on the root causes of conflict and civil war finds that a developing country's economic dependence on natural resources or other primary commodities is strongly associated with the risk level for violent conflict. This book brings together a collection of reports and case studies that explore what the international community in particular can do to reduce this risk.; The text explains the links between natural resources and conflict and examines the impact of resource dependence on economic performance, governance, secessionist movements and revel financing. It then explores avenues for international action - from financial and resource reporting procedures and policy recommendations to commodity tracking systems and enforcement instruments, including sanctions, certification requirements, aid conditionality, legislative and judicial instruments.

The recent escalation of world food prices – particularly for cereals - prompted mass public indignation and demonstrations in many countries, from the price of tortilla flour in Mexico to that of rice in the Philippines and pasta in Italy. The crisis has important implications for future government trade and food security policies, as countries re-evaluate their reliance on potentially more volatile world markets to augment domestic supplies of staple foods. This book examines how government policies caused and responded to soaring world prices in the particular case of rice, which is the world's most important source of calories for the poor. Comparable case studies of policy reactions in different countries, principally across Asia, but also including the USA, provide the understanding necessary to evaluate the impact of trade policy on the food security of poor farmers and consumers. They also provide important insights into the concerns of developing countries that are relevant for future international trade negotiations in key agricultural commodities. As a result, more appropriate policies can be put in place to ensure more stable food supplies in the future. Published with the Food and Agriculture (FAO) Organization of the United Nations

Consideration of the interactions between decisions made at one point in the supply chain and its effects on the subsequent stages is the core concept of a systems approach. Postharvest Handling is unique in its application of this systems approach to the handling of fruits and vegetables, exploring multiple aspects of this important process through chapters written by experts from a variety of backgrounds.Newly updated and revised, this second edition includes coverage of the logistics of fresh produce from multiple perspectives, postharvest handing under varying weather conditions, quality control, changes in consumer eating habits and other factors key to successful postharvest handling.The ideal book for understanding the economic as well as physical impacts of postharvest handling decisions.Key Features:*Features contributions from leading experts providing a variety of perspectives*Updated with 12 new chapters*Focuses on application-based information for practical implementation*System approach is unique in the handling of fruits and vegetables

Do regional approaches to affordable housing actually result in housing production and, if so, how? Regional Approaches to Affordable Housing answers these critical questions and more. Evaluating 23 programs across the nation, the report begins by tracing the history of regional housing planning in the U.S. and defining contemporary big picture issues on housing affordability. It examines fair-share regional housing planning in three states and one metropolitan area, and follows with an appraisal of regional housing trust funds--a new phenomenon. Also assessed are an incentive program in the Twin Cities region and affordable housing appeals statutes in Massachusetts, Rhode Island, and Connecticut. The study looks at recent private-sector initiatives to promote affordable housing production in the San Francisco Bay area and Chicago. A concluding chapter proposes a set of best and second-best practices. Supplementing the report are appendices containing an extensive annotated bibliography, a research note on housing need forecasting and fair-share allocation formulas, a complete list of state enabling legislation authorizing local housing planning, and two model state acts.
