Download or read book State of World Aquaculture 2006 written by Food and Agriculture Organization of the United Nations. Inland Water Resources and Aquaculture Service and published by Food & Agriculture Org.. This book was released on 2006 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture is developing, expanding and intensifying in almost all regions of the world, except in sub-Saharan Africa. Although the sector appears to be capable of meeting the gap between future demand and supply for aquatic food, there are many constraints and challenges which must be addressed in order to at least maintain the present level of per capita consumption at the global level. Key issues are the need for enhanced enforcement of regulation and better governance of the sector, as well as greater producer participation in the decision-making and regulation process. This publication examines past trends in aquaculture development as well as the current global status, drawing on a number of national and regional reviews.

Download or read book Aquatic Biodiversity written by Henri J. Dumont and published by Springer Science & Business Media. This book was released on 2003-11-30 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this age of increased fundamental and applied research on biodiversity, no single volume was as yet devoted to the various temporal and spatial aspects of aquatic biodiversity. The present book is published in honour of Professor Henri Dumont (Ghent, Belgium) at the occasion of his retirement as Editor-in-Chief of Hydrobiologia. The volume presents a selection of contributions on aquatic biodiversity, written by colleagues from the editorial board, fellow editors of aquatic journals and former students and collaborators. Contributions deal with a wide spectrum of topics related to aquatic biodiversity and cover fields such as actual- and palaeolimnology, taxonomy, and fundamental and applied limnology. Even reconnaissance chapters on management and cultural impact of water bodies are included. The book combines state-of-the-art contributions in aquatic sciences.

Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

Download or read book The Natural History of Madagascar written by Steven M. Goodman and published by . This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Separated from the mainland of Africa for 160 million years, Madagascar has evolved an incredible wealth of biodiversity, with thousands of species that can be found nowhere else on earth. For instance, of its estimated 12,000 plant species, nearly 10,000 are unique to Madagascar. Malagasy animals are just as spectacular, from its almost forty currently recognized species of lemurs—a primate group found only here—to the numerous species of tiny dwarf chameleons. With astounding frequency scientists discover a previously unknown species in Madagascar—and at almost the same rate another natural area of habitat is degraded or destroyed, a combination that recently led conservation organizations to name Madagascar one of the most important and threatened conservation priorities on the planet. The Natural History of Madagascar provides the most comprehensive, up-to-date synthesis available of this island nation's priceless biological treasures. Contributions by nearly three hundred world-renowned experts cover the history of scientific exploration in Madagascar, its geology and soils, climate, forest ecology, human ecology, marine and coastal ecosystems, plants, invertebrates, fishes, amphibians, reptiles, birds, and mammals. Detailed discussions of conservation efforts in Madagascar highlight several successful park reserve programs that could serve as models for other areas. Beautifully illustrated throughout, the book includes over one hundred color illustrations, with fifty color photos by nature photographer Harald Schütz, as well as more than three hundred black-and-white photographs and line drawings. The Natural History of Madagascar will be the invaluable reference for anyone interested in the Malagasy environment, from biologists and conservationists to policymakers and ecotourists.
