Available in PDF, EPUB and Kindle. Book excerpt: The 2020 edition of the WWDR, titled Water and Climate Change illustrates the critical linkages between water and climate change in the context of the broader sustainable development agenda. Supported by examples from across the world, it describes both the challenges and opportunities created by climate change, and provides potential responses – in terms of adaptation, mitigation and improved resilience – that can be undertaken by enhancing water resources management, attenuating water-related risks, and improving access to water supply and sanitation services for all in a sustainable manner. It addresses the interrelations between water, people, environment and economics in a changing climate, demonstrating how climate change can be a positive catalyst for improved water management, governance and financing to achieve a sustainable and prosperous world for all. The report provides a fact-based, water-focused contribution to the knowledge base on climate change. It is complementary to existing scientific assessments and designed to support international political frameworks, with the goals of helping the water community tackle the challenges of climate change, and informing the climate change community about the opportunities that improved water management offers in terms of adaptation and mitigation.

Download or read book The Mollusks written by Charles F. Sturm and published by Universal-Publishers. This book was released on 2006 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mollusks have been important to humans since our earliest days. Initially, when humans were primarily interested in what they could eat or use, mollusks were important as food, ornaments, and materials for tools. Over the centuries, as human knowledge branched out and individuals started to study the world around them, mollusks were important subjects for learning how things worked. In this volume, the editors and contributors have brought together a broad range of topics within the field of malacology. It is our expectation that these topics will be of interest and use to amateur and professional malacologists.

Download or read book Freshwater Mussel Ecology written by David L. Strayer and published by Univ of California Press. This book was released on 2008-06-10 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pearly mussels (Unionoidea) live in lakes, rivers, and streams around the world. These bivalves play important roles in freshwater ecosystems and were once both culturally and economically valuable as sources of food, pearls, and mother-of-pearl. Today, however, hundreds of species of these mussels are extinct or endangered. David L. Strayer provides a critical synthesis of the factors that control the distribution and abundance of pearly mussels. Using empirical analyses and models, he assesses the effects of dispersal, habitat quality, availability of fish hosts, adequate food, predators, and parasites. He also addresses conservation issues that apply to other inhabitants of fresh waters around the globe and other pressing issues in contemporary ecology.

Download or read book The Ecology of Freshwater Molluscs written by Robert T. Dillon and published by Cambridge University Press. This book was released on 2010-03-11 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here is a comprehensive review of the ecology of freshwater bivalves and gastropods worldwide. Robert Dillon discusses the ecology of these species in its broadest sense, including diet, habitat, and reproductive biology to emphasize the tremendous diversity of these freshwater invertebrates. He develops a new life history model that unifies them and reviews their population and community ecology, treating competition, predation, parasitism, and biogeography. Extensively referenced and synthesizing work from the nineteenth century through to the present day, this book includes original analyses that unify previous work into a coherent whole.
