Federal Standards and Procedures for the National Watershed Boundary Dataset (Wbd) by U.s. Department of Agriculture Pdf

The Watershed Boundary Dataset (WBD) is a compre- hensive aggregated collection of hydrologic unit data consis- tent with the national criteria for delineation and resolution. This document establishes Federal standards and procedures for creating the WBD as seamless and hierarchical hydrologic unit data, based on topographic and hydrologic features at a 1:24,000 scale in the United States, except for Alaska at 1:63,360 scale, and 1:25,000 scale in the Caribbean. The data within the WBD have been reviewed for certification through the 12-digit hydrologic unit for compliance with the criteria outlined in this document. Any edits to certified data will be reviewed against this standard prior to inclusion. Although not required as part of the framework WBD, the guidelines contain details for compiling and delineating the boundar- ies of two additional levels, the 14- and 16-digit hydrologic units, as well as the use of higher resolution base information to improve delineations. The guidelines presented herein are designed to enable local, regional, and national partners to delineate hydrologic units consistently and accurately. Such consistency improves watershed management through efficient sharing of information and resources and by ensuring that digital geographic data are usable with other related Geo- graphic Information System (GIS) data.

Assessing Risks to Endangered and Threatened Species from Pesticides by National Research Council,Division on Earth and Life Studies,Board on Environmental Studies and Toxicology,Committee on Ecological Risk Assessment Under FIFRA and ESA Pdf

The US Fish and Wildlife Service (FWS) and the National Marine Fisheries Service (NMFS) are responsible for protecting species that are listed as endangered or threatened under the Endangered Species Act (ESA) and for protecting habitats that are critical for their survival. The US Environmental Protection Agency (EPA) is responsible for registering or reregistering pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and must ensure that pesticide use does not cause any unreasonable adverse effects on the environment, which is interpreted to include listed species and their critical habitats. The agencies have developed their own approaches to evaluating environmental risk, and their approaches differ because their legal mandates, responsibilities, institutional cultures, and expertise differ. Over the years, the agencies have tried to resolve their differences but have been unsuccessful in reaching a consensus regarding their assessment approaches. As a result, FWS, NMFS, EPA, and the US Department of Agriculture asked the National Research Council (NRC) to examine scientific and technical issues related to determining risks posed to listed species by pesticides. Specifically, the NRC was asked to evaluate methods for identifying the best scientific data available; to evaluate approaches for developing modeling assumptions; to identify authoritative geospatial information that might be used in risk assessments; to review approaches for characterizing sublethal, indirect, and cumulative effects; to assess the scientific information available for estimating effects of mixtures and inert ingredients; and to consider the use of uncertainty factors to account for gaps in data. Assessing Risks to Endangered and Threatened Species from Pesticides, which was prepared by the NRC Committee on Ecological Risk Assessment under FIFRA and ESA, is the response to that request.

Fresh Water and Watersheds by Yeqiao Wang Pdf

Authored by world-class scientists and scholars, The Handbook of Natural Resources, Second Edition, is an excellent reference for understanding the consequences of changing natural resources to the degradation of ecological integrity and the sustainability of life. Based on the content of the bestselling and CHOICE-awarded Encyclopedia of Natural Resources, this new edition demonstrates the major challenges that the society is facing for the sustainability of all well-being on the planet Earth. The experience, evidence, methods, and models used in studying natural resources are presented in six stand-alone volumes, arranged along the main systems of land, water, and air. It reviews state-of-the-art knowledge, highlights advances made in different areas, and provides guidance for the appropriate use of remote sensing and geospatial data with field-based measurements in the study of natural resources. Volume 4, Fresh Water and Watersheds, covers fresh water and watersheds, their health and conservation, protection, and management. Organized for ease of reference, it provides fundamental information on groundwater storage, water quality, supply and balance, and water resource vulnerability. New in this edition are discussions on water footprint assessment, water surface dynamics, and water management on a global scale. Understanding the conditions of watersheds is crucial for restoring areas with degraded water quality as well as protecting healthy waters from emerging problems. This volume demonstrates the key processes, methods, and models used through several practical case studies from around the world. Written in an easy-to-reference manner, The Handbook of Natural Resources, Second Edition, as individual volumes or as a complete set, is an essential reading for anyone looking for a deeper understanding of the science and management of natural resources. Public and private libraries, educational and research institutions, scientists, scholars, and resource managers will benefit enormously from this set. Individual volumes and chapters can also be used in a wide variety of both graduate and undergraduate courses in environmental science and natural science at different levels and disciplines, such as biology, geography, earth system science, and ecology.

Remote Sensing of Hydrometeorological Hazards by George P. Petropoulos,Tanvir Islam Pdf

Extreme weather and climate change aggravate the frequency and magnitude of disasters. Facing atypical and more severe events, existing early warning and response systems become inadequate both in scale and scope. Earth Observation (EO) provides today information at global, regional and even basin scales related to agrometeorological hazards. This book focuses on drought, flood, frost, landslides, and storms/cyclones and covers different applications of EO data used from prediction to mapping damages as well as recovery for each category. It explains the added value of EO technology in comparison with conventional techniques applied today through many case studies.

Introduction to Forests and Renewable Resources by Chad P. Dawson,John C. Hendee Pdf

The introductory course in natural resources is broader and more diverse than ever. Today's students need to know how to manage forest, wildlife, watershed, and range resources in a variety of environments and serving the needs of myriad stakeholders. To that end, Chad Dawson has built on the foundation established by him and the late John Hendee to bring Introduction to Forests and Renewable Resources thoroughly up to date. The Ninth Edition has been reorganized to better address content—for example, policy and the differences between managing federal, state, and private land—that applies to all resources. While forests continue to be emphasized, more coverage is provided to other resources and to achieving management goals for multiple resources when considering topics like fire and recreation.

Scalar Mismatches in Metropolitan Water Governance by Francine van den Brandeler Pdf

The book provides insights into the particular nature of water-related challenges in metropolitan regions of the Global South and the “scalar mismatches” that prevent their sustainable and inclusive development. It argues for the adoption of a metropolitan water governance approach to assess these challenges, including the drivers and institutions that shape these, and the policy instruments at river basin and urban scales that aim to address these. The cases of Mexico City and São Paulo, as two mega-cities with a wide ranging of water-related challenges, present lessons to other fast growing urban agglomerations on the variety of possible responses as well as obstacles to their effectiveness that receive little attention.
