World Bank Discussion Paper No. 337. Draws on household survey data from 87 rural villages in Bangladesh to examine the contribution that government family planning programs, as well as other health care interventions, have made toward the recent reduction in fertility by increasing contraceptive use and reducing infant mortality. The paper suggests that the programs have been effective and finds that targeted credit program placement, such as the Grameen Bank and the Bangladesh Rural Advancement Committee (BRAC), contributed to the effort as well.

A Practitioner's Guide to Freshwater Biodiversity Conservation brings together knowledge and experience from conservation practitioners and experts around the world to help readers understand the global challenge of conserving biodiversity in freshwater ecosystems. More importantly, it offers specific strategies and suggestions for managers to use in establishing new conservation initiatives or improving the effectiveness of existing initiatives. The book: offers an understanding of fundamental issues by explaining how ecosystems are structured and how they support biodiversity; provides specific information and approaches for identifying areas most in need of protection; examines promising strategies that can help reduce biodiversity loss; and describes design considerations and methods for measuring success within an adaptive management framework. The book draws on experience and knowledge gained during a five-year project of The Nature Conservancy known as the Freshwater Initiative, which brought together a range of practitioners to create a learning laboratory for testing ideas, approaches, tools, strategies, and methods. For professionals involved with land or water management-including state and federal agency staff, scientists and researchers working with conservation organizations, students and faculty involved with freshwater issues or biodiversity conservation, and policymakers concerned with environmental issues-the book represents an important new source of information, ideas, and approaches.

Integrating research into freshwater biodiversity and the role of keystone species, this fascinating book presents freshwater crayfish as representatives of human-exacerbated threats to biodiversity and conservation. It uses examples from these and other large decapod invertebrates to explore how communities function and are controlled, alongside the implications of human demands and conflicts over limited resources, notably the severe impacts on biodiversity. The discussion is structured around three key topics – the present situation of crayfish in world freshwater ecosystems, the applications of science to conservation management and knowledge transfer for successful crayfish management. It outlines the historic exploitation of crayfish, addressing the problems caused by invasive alien forms and explaining the importance of correct identification when dealing with conservation issues. Offering a global perspective on freshwater systems, the book ultimately highlights how the conservation of such large and long-lived species will help protect ecosystem quality in the future.

One of the main reasons cited for inadequate representation of biodiversity in the development processes is a lack of readily available information on inland water taxa. In response to this need for basic for information on species, the IUCN Species Programme conducted a regional assessment of the status and distribution of 2,261 taxa of freshwater fishes, molluscs, odonates, crabs and selected families of aquatic plants from throughout central Africa. This study is based on the collation and analysis of existing information, and the knowledge of regional experts.

This assessment is the first overview of the conservation status of 877 northern African freshwater species belonging to five taxonomic groupsfish, molluscs, dragonflies and damselflies, freshwater crabs and aquatic plantsin accordance with the IUCN regional Red List guidelines. Species at risk of regional extinction are mapped and conservation measures are proposed to reduce the probability of future declines.

Fresh waters are disproportionately rich in species, and represent global hotspots of biodiversity. However, they are also hotspots of endangerment.

This new volume examines the ecological importance, threats, protection, and management of the biodiversity of freshwater ecosystems, such as lakes, ponds, rivers, streams, reservoirs, pools, and wetlands. As populations have been increasing exponentially, humans are using freshwater ecosystems severely, resulting in habitat destruction and breakdown. Environmental contamination, climate change, the introduction of harmful and invasive organisms, unplanned dredging and de-weeding processes, disposal of sewer systems in freshwater bodies, and badly planned water diversions are the leading causes of habitat loss in freshwaters. These impacts have led to significant decreases in the numbers and productivity of many freshwater species and decreased biodiversity in freshwater. This book presents a selection of primary research and review papers on several freshwater aquatic biodiversity studies, which involve evaluating plants, macroinvertebrates, macrophytes, benthic zones, and fish diversity in freshwater ecosystems. It provides an abundance of new information on freshwater biodiversity distribution, status, and patterns. Key features: Discusses the importance, threats, and management of biodiversity of freshwater ecosystems Provides detailed coverage of modern and updated techniques used in the evaluation and conservation of freshwater biodiversity Looks at the impact of pesticides pollution on freshwater environs, and on aquatic and terrestrial life Reviews how global climate change affects freshwater biodiversity Biodiversity of Freshwater Ecosystems: Threats, Protection, and Management promotes the enhancement and strengthening of freshwater protection and its unique biodiversity for scientists, policymakers, scholars, researchers, NGOs, and the public, providing necessary background knowledge and practical tools to help manage aquatic ecosystems and their biodiversity in a holistic manner.
