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.

This book offers a comprehensive account of the current state of inland waters in tropical and subtropical East Asia, exploring a series of case studies of freshwater fish, reptiles, amphibians, birds, mammals and water bodies at particular risk. The book highlights the rich freshwater biodiversity of tropical East Asia and draws attention to the various threats it faces due to human activities and rapid environmental change. It addresses the question of whether the contributions of these animals and habitats, or biodiversity in general, to ecosystem functioning and service provision provide sufficient basis for arguments supporting nature conservation. Drawing on instances from the rivers and lakes of tropical East Asia, the book also asks whether the benefits accruing from intact ecosystems are likely to be enough to ensure their preservation. If the answer to either or both these questions is ‘no’, then what are the prospects for freshwater biodiversity in rapidly changing tropical East Asia? This book will be of interest to students and scholars of biodiversity, conservation, freshwater ecology, ecosystem services and Asian Studies.

This book is part of a two-volume set that offers an innovative approach towards developing methods and tools for assigning conservation categories of threatened taxa and their conservation strategies by way of different phases of eco-restoration in the context of freshwater river systems of tropical bio-geographic zones. The set provides a considerable volume of research on the biodiversity component of river ecosystems, seasonal dynamics of physical chemical parameters, geo-hydrological properties, types, sources and modes of action of different types of pollution, river restoration strategies and methodologies for the ongoing ecological changes of river ecosystems. Volume 2 highlights biodiversity potential in aiding the resistance and resilience of riverine ecosystem functioning and their synergistic effects on ongoing environmental perturbations. Comprehensive information on the conservation of river-associated-wildlife is provided, covering the impacts of pollution, land-use changes, river policies, and ecosystem restoration strategies. The book offers an innovative approach towards developing methods and tools for assigning conservation categories of threatened taxa, and covers their conservation strategies by way of different phases of eco-restoration in the context of freshwater river systems of tropical bio-geographic zones.

Freshwater Fishes of the Eastern Himalayas provides a guide to describe the internationally accepted methods used in the accurate identification of fishes, morphometry, i.e., body proportions, meristics, i.e., counts of countable characters, viz., scales, fin rays, pores, vertebrae etc., characters of bones wherever necessary, special characters, viz., serrations of fin spines, axillary lobes, lobes, color patterns, etc. All the available taxa of the region are covered, making this an essential reference that provides the original description of genera and species. Diagnostic characters in the book can be easily examined by an unaided eye or by a binocular dissecting microscope with transmitted light. Provides diagnostic characters which are unique for a species or a combination of characters to differentiate each species from its congeners Includes both verbal and technical aspects, along with color illustrations of the particular part of the fish showing the distinguishing character Presents diagnostic characters, illustrations or images of the fish and of its parts, showing the unique character and distribution to make it easy for species identification

Biodiversity is declining at an alarming rate due to anthropogenic activities around the world. This book is the first volume in the new series Biodiversity Hotspots of the World, which highlights the 36 hotspot regions of the world, regions that were designated as reaping maximum benefit from preservation efforts. This series is our humble attempt to document these hotspots as a conservation and preservation measure. This first volume in the series focuses on the Western Ghats and Sri Lanka, construed as forming a community of species because of their shared biogeographical history. The volume explores the diversity and conservation efforts of the extraordinarily rich species found here, including plants, many of which are found nowhere else in the world; forests, which face tremendous population pressure and have been dramatically impacted by demands for timber and agricultural land; as well as the hotspot’s diverse mammals, birds, insects, and amphibian species, and more. The volumes in this series will be essential resources for researchers and practitioners in the fields of conservation biology, ecology, and evolution.

The impact of invasive species is second only to that of human population growth and associated activities as a cause of the loss of biodiversity throughout the world. In the United States, invasions of nonnative plants, animals, or microbes cause major environmental damage. The second edition of Biological Invasions: Economic and Environmental Cos

Biodiversity and Climate Change Adaptation in Tropical Islands provides comprehensive information on climate change, biodiversity, possible impacts, adaptation measures and policy challenges to help users rehabilitate and preserve the natural resources of tropical islands. While biodiversity and climate change of tropical islands has previously received less attention, it is ironically one of the most vulnerable regions in this regard. The core content of the work derives largely from the ideas and research output from various reputed scientists and experts who have recorded climate change impacts on aquatic and coastal life in tropical regions. Contributors have direct working experience with the tribes in some of the tropical islands. All of their expertise and information is compiled and presented in the work, including coverage related to climate change. This work highlights the ever-growing need to develop and apply strategies that optimize the use of natural resources, both on land and in water and judicious use of biodiversity. It functions as a critical resource on tropical island biodiversity for researchers, academicians, practitioners and policy makers in a variety of related disciplines. Covers a huge range of biodiversity documentation, conservation measures and strategies that can be applied to various sectors, from forests to agriculture Brings together expertise from researchers in the area who have direct experience in the regions described Contains a wealth of field research related to biodiversity conservation and its applications from a variety of tropical islands
