Theories Methods And Practices Of Wetland Degradation And Restoration

Creating and Restoring Wetlands: From Theory to Practice, Second Edition describes the challenges and opportunities relating to the restoration of freshwater and estuarine wetlands in natural, agricultural, and urban environments in the coming century. This second edition is structured by clearly defined chapters based on specific wetland types (e.g. Peatlands, Mangroves) and with a consistent and coherent organization for ease of discoverability. The table of contents is divided into four main subjects: Foundations, Restoration of Freshwater Wetlands, Restoration of Estuarine Wetlands, and From Theory to Practice, each with multiple chapters. Part 1, Foundations, contains chapters describing definitions of wetlands, ecological theory used to guide restoration, and considerations on where to implement restoration on the landscape. In Parts 2 and 3, restoration of specific freshwater (marshes, forests, peatlands) and estuarine (tidal marshes, mangroves) wetlands are described. Part 4, From Theory to Practice, contains chapters describing performance standards to gauge success of projects and case studies describing small-scale and large-scale restoration projects of various freshwater and estuarine wetlands. Each chapter contains clearly labeled sections which assist the reader to quickly and easily key in on the subject matter that they are seeking. The approach of Creating and Restoring Wetlands is unique in that, in each chapter, it links ecological theory important to ecosystem restoration with practical techniques to undertake and implement successful wetland restoration projects, including recommendations for performance standards to gauge success as well as realistic expectations and timescales for achieving success. Each chapter ends with a summary table describing keys to ensure success for a given wetland ecosystem. Each chapter ends with a summary table describing keys to ensure success for a given wetland ecosystem Written by a single author, providing a consistent structure that is coherent, cohesive and well referenced Contains case studies of small- and large-scale restoration activities ensuring relevance to individuals and organizations

Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

An Approach to Improving Decision-Making in Wetland Restoration and Creation succinctly compares populations of natural and created wetlands to determine whether restored wetlands successfully replace wetlands lost to development or other pressures. The book also presents strategies for mitigation of wetland losses, site selection for wetland restoration projects, and assessment of the level of attainable function for restored wetlands. The book is a significant resource for helping wetland professionals, planners, and ecologists formulate decisions affecting the creation and restoration of wetlands.

The public's interest in the renewal of natural ecosystems has grown steadily during the past few decades. While preservation of habitat is a key to environmental health, there is a growing awareness that restoration, creation, and enhancement are essential to recover ecosystems that have been degraded or destroyed. Wetland habitats are the focus of many recovery efforts because over the past 200 years the area and health of wetlands have declined significantly. Less than 46 percent of the 215 million acres of wetlands estimated to exist in the contiguous U.S. when Europeans arrived remain. Prior to the mid-1970s, the draining and destruction of wetlands were accepted practices. Many wetlands altered by humans were drained to support agricultural uses, while others were filled for urban development, diked for water impoundments or to diminish flooding, or dredged for marinas and ports. Indirect impacts from pollutants, urban runoff, and invasion by non-native species continue to degrade and destroy wetlands. Scientists and policy makers also recognize the value of wetland restoration. In 1992, scientists completed a study for the National Research Council that called for the development of a national wetlands restoration strategy. Since then, federal agencies have been working with partners to achieve a net increase of 100,000 acres of wetlands per year by 2005. This goal will be reached only through carefully planned and implemented restoration and creation projects that add ecologically valuable wetlands to the landscape. States and the federal government are funding and conducting large-scale ecosystem restorations, such as the South Florida/Everglades Ecosystem Restoration, which are contributing to the national wetland goal. However, without the support of citizens and local groups around the country the 100,000 acre per year goal cannot be reached. For many decades, citizens have been restoring, creating, and enhancing wetland habitats through local non-profit organizations. In addition, citizens have become involved in wetland projects through government programs. Despite these efforts, the nation is still losing more wetlands than it gains each year. This document is designed to support and further encourage landowner and community-based wetland projects.

This book gathers the peer-reviewed proceedings of the 1st congress on Geoethics & Groundwater Management (GEOETH&GWM'20), held in Porto, Portugal, in an online format on 18-22 May 2020. Hosted in School of Engineering (ISEP), Polytechnic of Porto based on Porto city (a UNESCO World Heritage Site), the international conference focused on what has now been dubbed “hydrogeoethics”, a novel transdisciplinary, scientific field integrating all dimensions of geoethics in groundwater science and practice. Given its scope, the book is of interest to all researchers and practitioners in the geosciences, hydrology, water resources, hydrogeology, natural resources management, environment, engineering, law, sociology, education, philosophy, culture, among others. This joint congress is the result of a collaborative agreement between the IAH (International Association of Hydrogeologists) and IAPG (International Association for Promoting Geoethics) and reflects the need for concerted actions to achieve sustainable development. The diversity, scale, significance and increasing magnitude of anthropogenic interactions with aquifers and groundwater, which often involve conflicting values or interests, call for analysis, discussions and decisions on the part of the agents involved, e.g. groundwater scientists, policymakers, managers, organisations, professionals and citizens. This approach calls for a responsible, sustainable and human approach to groundwater use and management. The groundwater community involved in the exploration and exploitation, use and management of this increasingly vital natural resource is becoming more and more aware that ethical issues pervade all our attitudes from concept to action and need to be addressed. Diverse values and cultures, science and education, law and policies, human and natural environments and the public and the economic sectors view groundwater and its value and/or role differently. The authors believe that in a globalised and interconnected world, common ground must be found in the interest of peace, human development and sustainability. The main topics covered here include: 1. Fundamentals of hydrogeoethics: cultures, principles and geoethical values on groundwater science and engineering 2. Lessons for a resilient and sustainable future with hydrogeoethics: case studies of geoethics in groundwater science-engineering, profession, and management 3. Scientific and humanistic components of hydrogeoethics in groundwater education and professional training 4. Socio-hydrogeology and ethical groundwater management 5. Geoethics of decision making under uncertainty and ethical issues in neglecting groundwater functioning 6. Groundwater: geological, legal, social, and ethical challenges of a unique natural resource
