Available in PDF, EPUB and Kindle. Book excerpt: This publication explores how the international Nile perch fish chain should or can be organised to improve both welfare of local communities, sustainability of the fisheries and quality of the fish. Primary producers face a number of bottlenecks such as poor access to production facilities, ineffective enforcement of sustainable practices, lack of market (price) information, competition with international markets and degradation of the fisheries that lead to increasing food insecurity problems. In order to improve sustainability and quality, primary producers are open to contracts that enable them better access to production facilities and price information, and also to better integrate them into international channels. Sustainable practices can or should be part of these contracts. Although the downstream channel members and other stakeholders were not fully aware of the complexity and gravity of the upstream problems, they appeared to be willing to help to improve the situation at Lake Victoria. It is therefore a corporate social responsibility for the downstream channel members, as well as nature conservation organizations and the donor community, to empower the primary producers and local communities in developing countries to implement welfare, sustainability and quality-enhancing practices. This publication outlines several mechanisms to achieves these goals.
Download or read book Darwin s Dreampond written by Tijs Goldschmidt and published by MIT Press. This book was released on 1998 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darwin's Dreampondtells the evolutionary story of the extraordinary "furu" and the battlefield leading to extinction. Tijs Goldschmidt skillfully blends a masterful discussion of the principles of neo-Darwinian evolution and speciation with a history of Lake Victoria's ecosystem. The science unfolds in the context of the engaging first-person narrative of Goldschmidt's adventures and misadventures as a field researcher. An astute observer and a clear and witty writer, he warmly portrays the colors and textures of the landscapes and the lives of the local people as he interacts with them during the course of his fieldwork.

Download or read book Freshwater Biodiversity written by David Dudgeon and published by Cambridge University Press. This book was released on 2020-05-21 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Birth of the Anthropocene written by Jeremy Davies and published by Univ of California Press. This book was released on 2016-05-24 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world faces an environmental crisis unprecedented in human history. Carbon dioxide levels have reached heights not seen for three million years, and the greatest mass extinction since the time of the dinosaurs appears to be underway. Such far-reaching changes suggest something remarkable: the beginning of a new geological epoch. It has been called the Anthropocene. The Birth of the Anthropocene shows how this epochal transformation puts the deep history of the planet at the heart of contemporary environmental politics. By opening a window onto geological time, the idea of the Anthropocene changes our understanding of present-day environmental destruction and injustice. Linking new developments in earth science to the insights of world historians, Jeremy Davies shows that as the Anthropocene epoch begins, politics and geology have become inextricably entwined.
Download or read book Freshwater Microplastics written by Martin Wagner and published by Springer. This book was released on 2017-11-21 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY 4.0 license. This volume focuses on microscopic plastic debris, also referred to as microplastics, which have been detected in aquatic environments around the globe and have accordingly raised serious concerns. The book explores whether microplastics represent emerging contaminants in freshwater systems, an area that remains underrepresented to date. Given the complexity of the issue, the book covers the current state-of-research on microplastics in rivers and lakes, including analytical aspects, environmental concentrations and sources, modelling approaches, interactions with biota, and ecological implications. To provide a broader perspective, the book also discusses lessons learned from nanomaterials and the implications of plastic debris for regulation, politics, economy, and society. In a research field that is rapidly evolving, it offers a solid overview for environmental chemists, engineers, and toxicologists, as well as water managers and policy-makers.

Download or read book Sustainable Fishery Systems written by Anthony Charles and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive attempt to adopt an 'integrated' interdisciplinary approach to the study of fisheries. Fisheries are discussed as holistic 'systems', with emphasis on their structure, operation and dynamics. The book's interdisciplinary approach is applied to an analysis of problems faced in pursuing 'sustainable fisheries', with emphasis on six dominant themes: sustainability, uncertainty, complexity, conflict, fishing rights and the nature of management. Within this discussion, several major directions in current fishery thinking are explored, notably the precautionary approach, the ecosystem approach, co-management, and robust management for resilient fisheries.
Download or read book Environmental Change and Response in East African Lakes written by J.T. Lehman and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea for this book was born at the June 1996 meeting of the IDEAL Steering Committee in Milwaukee, Wisconsin. We had just completed a successful and stimulating special symposium during the annual meeting of the American Society for Limnology and Oceanography, and enthusiasm was running high for the production of a volume that could assemble in one place the scientific findings that were starting to emerge from East Africa. IDEAL, an International Decade for the East African Lakes, had ended one round of field investigations, many of which had been centered on Lake Victoria. As the climatologists, geologists, paleolimnologists, and biologists displayed their results and debated interpretations, it appeared that some paradigms were shifting, and that new explanations of climate history and modem processes were taking shape. The Steering Committee endorsed the production of a volume that would draw together the different research results that were emerging and which would be representative of the scope of science issues that exist within IDEAL. This book follows in the spirit of The Limnology, Climatology, and Paleoclimatology of the East African Lakes, published in 1996, but has a somewhat different purpose. The previous publication also included original science results, but it was conceived to review the state of knowledge, identify critical problems, and point to new paths of inquiry. It accompanied the development of our first Science and Implementation Plan for the East African Lakes.
Download or read book The Small Scale Fisheries Guidelines written by Svein Jentoft and published by Springer. This book was released on 2017-06-10 with total page 850 pages. Available in PDF, EPUB and Kindle. Book excerpt: In June 2014, FAO member-states endorsed the Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries (SSF Guidelines). These Guidelines are one of the most significant landmarks for small-scale fisheries around the world. They are comprehensive in terms of topics covered, and progressive, with their foundations based on human rights and other key principles. It can be anticipated that implementing the SSF Guidelines, whether at local, national, or regional levels, will be challenging. This book contains in-depth case studies where authors discuss the extent to which the Guidelines can help improve the realities of small-scale fishing men and women globally and make their livelihoods and communities more secure. This will require policy intervention and innovation, along with contributions of civil society organizations and academia. However, most of all it will necessitate the empowerment of fishing people so that they can become active participants in decision making on matters where their well-being and human rights are at stake. By endorsing the SSF Guidelines, states have committed themselves to support and facilitate this development. This book asks whether states can successfully “walk the talk,” and provides advice as to how they can do so. The collection of case studies sets the platform for an interactive dialogue space for researchers, policy makers, civil society and small-scale fishing communities to start the conversation about the monitoring and evaluation of the implementation of the SSF Guidelines at local, national, regional and global levels. An added value is that it helps add focus to our work as civil society activists involved in ensuring the application of the SSF Guidelines. Naseegh Jaffer – General Secretary, World Forum of Fisher People (WFFP) This collection offers many ways in which institutions enabling small-scale fisheries can protect and promote sustainability, food security, customary tenure, self-management, and market access, while fostering such benefits as ecosystem-based management, protected areas, incorporation of local knowledge, and poverty alleviation. You will want to put this book in the hands of policy-makers and practitioners immediately -- and for years to come. Evelyn Pinkerton – Professor, Simon Fraser University, Canada
