Most water resources managers, scientists, and other experts would agree that nonpoint source pollution is a more pressing and challenging national water quality problem today than point source pollution. Nonpoint sources of pollutants include parking lots, farm fields, forests, or any source not from a discrete conveyance such as a pipe or canal. Of particular concern across the Mississippi River basin (MRB) are high levels of nutrient loadings--nitrogen and phosphorus--from both nonpoint and point sources that ultimately are discharged into the northern Gulf of Mexico (NGOM). Nutrients emanate from both point and nonpoint sources across the river basin, but the large majority of nutrient yields across the MRB are nonpoint in nature and are associated with agricultural activities, especially applications of nitrogen-based fertilizers and runoff from concentrated animal feeding operations. Improving Water Quality in the Mississippi River Basin and Northern Gulf of Mexico offers strategic advice and priorities for addressing MRB and NGOM water quality management and improvements. Although there is considerable uncertainty as to whether national water quality goals can be fully realized without some fundamental changes to the CWA, there is general agreement that significant progress can be made under existing statutory authority and budgetary processes. This book includes four sections identifying priority areas and offering recommendations to EPA and others regarding priority actions for Clean Water Act implementation across the Mississippi River basin. These sections are: USDA's Mississippi River Basin Healthy Watersheds Initiative; Numeric Water Quality Criteria for the northern Gulf of Mexico; A Basinwide Strategy for Nutrient Management and Water Quality; and, Stronger Leadership and Collaboration.

Through creative combinations of ethnohistoric evidence, iconography, and contextual analysis of faunal remains, this work offers new insight into the mechanisms involved in food provisioning for complex societies. Contributors combine zooarchaeological and historical data from global case studies to analyze patterns in centralization and bureaucratic control, asymmetrical access and inequalities, and production-distribution-consumption dynamics of urban food provisioning and animal management. Taking a global perspective and including both prehistoric and historic case studies, the chapters in the volume reflect some of the current best practices in the zooarchaeology of complex societies. Embedding faunal evidence within a broader anthropological explanatory framework and integrating archaeological contexts, historic texts, iconography, and ethnohistorical sources, the book discerns myriad ways that animals are key contributors to, and cocreators of, complex societies in all periods and all places. Chapters cover the diverse sociopolitical and economic roles wild animals played in Bronze Age Turkey; the production and consumption of animal products in medieval Ireland; the importance of belief systems, politics, and cosmologies in Shang Dynasty animal provisioning in the Yellow River Valley; the significance of external trade routes in the kingdom of Aksum (modern Sudan); hunting and animal husbandry at El Zotz; animal economies from two Mississippian period sites; and more. Food Provisioning in Complex Societies provides an optimistic roadmap and heuristic tools to explore the diverse, resilient, and contingent processes involved in food provisioning. The book represents a novel and productive way forward for understanding the unique, yet predictably structured, provisioning systems that emerged in the context of complex societies in all parts of the world. It will be of interest to zooarchaeologists and archaeologists alike. Contributors: Joaquin Arroyo-Cabrales, Fiona Beglane, Roderick Campbell, Kathryn Grossman, Patricia Martinez-Lira, Jacqueline S.
