Book Description
"Even though progress towards the MDG target represents important gains in access for billions of people around the world, it has been uneven. Sharp geographic, sociocultural and economic inequalities in access persist and sometimes have increased. This report presents examples of unequal progress among marginalized and vulnerable groups. Section 1 presents the status of and trends in access to improved drinking water sources and sanitation. Section 2 provides a snapshot of inequalities in access to improved drinking water sources and sanitation. Section 3 presents efforts to strengthen monitoring of access to safe drinking water and sanitation services under a post-2015 development agenda, as well as the challenges associated with these efforts."--Publisher's website.

Book Description
Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.
Riverine Ecosystem Management

Publisher : Springer
Page : 562 pages
File Size : 25,10 MB
Release : 2018-05-08
Category : Science
ISBN : 3319732501
Book Description
This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

Tropical Stream Ecology
Author : David Dudgeon
Publisher : Elsevier
Page : 343 pages
File Size : 41,24 MB
Release : 2011-05-04
Category : Science
ISBN : 0080557171
Book Description
Tropical Stream Ecology describes the main features of tropical streams and their ecology. It covers the major physico-chemical features, important processes such as primary production and organic-matter transformation, as well as the main groups of consumers: invertebrates, fishes and other vertebrates. Information on concepts and paradigms developed in north-temperate latitudes and how they do not match the reality of ecosystems further south is expertly addressed. The pressing matter of conservation of tropical streams and their biodiversity is included in almost every chapter, with a final chapter providing a synthesis on conservation issues. For the first time, Tropical Stream Ecology places an important emphasis on viewing research carried out in contributions from international literature. - First synthetic account of the ecology of all types of tropical streams - Covers all of the major tropical regions - Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems - Threats faced by tropical stream ecosystems and possible conservation actions - Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)
Second Assessment of Climate Change for the Baltic Sea Basin

Release : 2015-04-03
Category : Science
ISBN : 3319160060
Book Description
This book is an update of the first BACC assessment, published in 2008. It offers new and updated scientific findings in regional climate research for the Baltic Sea basin. These include climate changes since the last glaciation (approx. 12,000 years ago), changes in the recent past (the last 200 years), climate projections up until 2100 using state-of-the-art regional climate models and an assessment of climate-change impacts on terrestrial, freshwater and marine ecosystems. There are dedicated new chapters on sea-level rise, coastal erosion and impacts on urban areas. A new set of chapters deals with possible causes of regional climate change along with the global effects of increased greenhouse gas concentrations, namely atmospheric aerosols and land-cover change. The evidence collected and presented in this book shows that the regional climate has already started to change and this is expected to continue. Projections of potential future climates show that the region will probably become considerably warmer and wetter in some parts, but dryer in others. Terrestrial and aquatic ecosystems have already shown adjustments to increased temperatures and are expected to undergo further changes in the near future. The BACC II Author Team consists of 141 scientists from 12 countries, covering various disciplines related to climate research and related impacts. BACC II is a project of the Baltic Earth research network and contributes to the World Climate Research Programme.
Global Perspectives on River Conservation

ISBN :
Book Description
This is the first book to provide a truly global synthesis of knowledge on river conservation, and will be an invaluable reference for all those concerned with strategic river planning. Throughout the world, river ecosystems frequently reflect the worst excesses of human exploitation for instance when rivers are used as repositories for waste. Recognition is growing that river management needs to move from chemical clean-up to restoring the structural damage caused by decades of river engineering. There needs to be a catchment-wide perspective if the needs of human populations, river habitats and wildlife are to reach a sustainable balance. Against this backdrop, the development of river conservation strategies has become a global imperative. This book sets out a worldwide, region-by-region overview of the science, policy and practice of river conservation. It also provides a topical review of different river settings (such as tropical/temperate; temporary/perennial; large/small) and contemporary issues in river conservation (such as classification and evaluation; environmental legislation; the role of public participation). Clearly written by leading researchers in the field, this book will be welcomed by all those working on environmental management of inland waters as well as academics, researchers, postgraduates and final year undergraduates.
