Freshwater Biodiversity in Asia


Book Description

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.










Freshwater Biodiversity


Book Description

Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.







Biodiversity of Fishes in Arunachal Himalaya


Book Description

Biodiversity of Fishes in Arunachal Himalaya: Systematics, Classification, and Taxonomic Identification provides a detailed piscatorial resource of the fish species living in the rich mountain waterbodies of the eastern Himalayan region. It presents the latest classifications and updated taxa of fish dwelling in high-altitude cold waters, mid-altitude cold and warm waters, and warm waters in the low altitude foothill regions of the Arunachal Himalaya. The book includes the scientific and vernacular names of more than 200 fish species, as well as coloration, distributional and conservational status. It addresses increasing threats to the endemic fishes of this region, including habitat shrinkage, habitat destruction, and more. This book will be a valuable resource for biodiversity and conservation researchers, especially those specializing in ichthyo-faunal diversity. Fishery researchers and students will also find the information presented on taxonomic and classification very useful to their initiatives. - Documents the taxonomy of 218 freshwater fish species from the headwaters of the Brahmaputra basin - Includes quality photographs of each species, either in the wild or as fresh specimens, for easy visual identification - Provides species registration numbers and key distinguishing features for fast field and research references




Biological Diversity


Book Description

One of the cornerstones of life's wonders is the vast array of species filling the planet. From plants to animals to humans, there is no shortage of beings to provide 'spice of life' variety is said to be. Periodically, scientists announce the discovery of a 'new' form of life, so it seems as if Earth is capable of producing new species just to keep us on our toes. At times, the immense breadth of living things can even feel overwhelming, as one pauses to ponder how numerically insignificant humans are when compared to the insect population. Given the biological diversity of the planet, it is incumbent upon humans to safeguard the natural beauty of the environment. To that end, conservation takes on special importance, necessitating the balancing of industrial expansion with preserving the flora and fauna surrounding us. This book is an important tool in understanding and researching the many different life forms spanning the globe. Collected here is a substantial and carefully selected listing of relevant literature on biological diversity and its conservation. Following this bibliography are author, title, and subject indexes to allow for further access to this information. The sheer bulk of the works about biological diversity can be so intimidating that a book such as this one becomes useful in sorting through the resources about the importance of life's variety.




The Mekong


Book Description

The Mekong is the most controversial river in Southeast Asia, and increasingly the focus of international attention. It flows through 6 counties, China, Myanmar, Laos, Thailand, Cambodia and Viet Nam. The 4 downstream countries have formed the Mekong River Commission to promote sustainable development of the river and many of their people depend on it for their subsistence ? it has possible the largest freshwater fishery in the world, and the Mekong waters support rice agriculture in the delta in Viet Nam (which produces about 40% of that country's food) as well as in Cambodia, Laos and Thailand. China is now building the first large mainstream dam on the river, and has proposals for several more. These dams are likely to affect the downstream countries. Several of the downstream countries also have plans for large scale hydropower and irrigation development which could also impact the river. This book will provide a solid overview of the biophysical environment of the Mekong together with a discussion of the possible impacts, biophysical, economic and social, of some possible development scenarios. It is intended to provide a technical basis which can inform the growing political and conservation debate about the future of the Mekong River, and those who depend on it. It is aimed at river ecologists, geographers, environmentalists and development specialists both in the basin and (especially) outside for whom access to this material is most difficult. This book will be the first comprehensive treatment of the Mekong system. - The first comprehensive overview of all aspects of the Mekong River system - Deals with a regionally critical ecosystem and one under threat - The Mekong supports the world's largest freshwater fishery and provides water underpinning a major regional rice paddy system - Presents the authoritative findings of the Mekong River Commission's research for a wider audience for the first time outside of limited distribution reports
