Review of the state of the world fishery resources: Inland fisheries

ISBN: 9251307938
Category : Technology & Engineering
Languages : en
Pages : 399
Book Description
The FAO Fishery and Aquaculture Circular C942 Revision 3 (C942 Rev. 3) updates and expands the scope of previous revisions of the circular. C942 Rev. 3 is an important baseline document, intended to assist in the global understanding of inland fisheries and inform dialogue on their current and future role. The third revision reviews the status and trends of inland fisheries catch at global, continental and subcontinental levels. It places inland capture fisheries in the context of overall global fish production, and calls attention to the importance of inland capture fisheries with respect to food security and nutrition and the Sustainable Development Goals. It quantifies global inland fisheries resources in terms of food production, nutrition, employment, economic contribution with respect to those countries/regions or subnational areas where they are important. A characterization approach to distinguish large-scale and small-scale fishing operations and their relative contributions is provided. The review provides estimated economic values of inland fisheries, as well as a valuation of potential replacement cost of these (in terms of dollars, other resources such as land and water, feeds). There is also an analysis of the extent and economic value of recreational inland fisheries. The contribution to employment and the gender differences related to this are quantified. The linkages between inland fisheries and biodiversity are also explored. C942 Rev. 3 discusses ways to measure and assess inland fisheries, in particular, how to establish more accurately inland fishery catches in the many situations where there are challenges to collection of catch statistics.
Freshwater small pelagic fish and their fisheries in the major African lakes and reservoirs in relation to food security and nutrition

Book Description
Small pelagic fish species found in lakes and introduced to reservoirs dominate by volume and contribute some of the most important inland fisheries in Africa with steadily increasing catches and additional potential. This circular reviews the status and importance of the pelagic fish and fisheries, together with small fish in general, for sustainable and healthy livelihoods in Africa. It reviews the biology and biological production of the most important pelagic species in lakes and reservoirs as well as the impacts of environmental and climatic variation on the stocks of these species. It examines and discuss the various capture techniques together with potential of improvements in the fisheries and associated processing and national and regional trade within Africa. The knowledge generated by the circular will be useful for policy makers and development practitioners to design and implement more effective policies, strategies and programs that will contribute to reducing the food insecurity and conflicts that currently affect the people in sub-Saharan Africa.
Sustainable Hydropower in West Africa

ISBN: 0128130172
Category : Technology & Engineering
Languages : en
Pages : 236
Book Description
Sustainable Hydropower in West Africa: Planning, Operation, and Challenges provides a comprehensive overview of the planning, deployment and management of hydropower in West Africa and similar regions. The authors use a practical approach to analyze available technology, modeling methodologies and sustainability aspects, such as the dependence between climate and hydropower, and socio-economic and environmental impacts. They discuss the need for innovative solutions and how to close research gaps in the field for this region. Although more than 50% of West Africa’s hydropower potential is still untapped, re-engineering and maintenance of existing hydropower plants is a key issue and is discussed. Issues of productivity and optimization are also covered, as well as the introduction of new technology and integration of hydropower into existing energy systems—renewable energy systems, in particular. Policy and regulation are also examined, considering competing needs when managing water resources. The final chapter offers a summary of activities, strategies, policies and technology for easy reference and practical use. Due to its wide coverage and real life examples, this is a useful reference for engineering professionals in the field of hydropower, working in West Africa and regions with similar conditions. This book helps engineers make technology and location decisions for planning, deploying and operating hydropower plants. The book’s accessible language and international authorship also allows for easy use by energy researchers, analysts and policy makers who need information for the analysis, modeling, financing, implementation and regulation of hydropower in West Africa and related regions. Presents the most current issues related to hydropower deployment and management in West Africa and regions with similar conditions Discusses key challenges, focusing on practical aspects and methodologies Explores the technological, sustainability and economic aspects to be considered when deploying, operating and maintaining hydropower plants in West Africa and similar regions
Diagnostic study of the Volta Basin fisheries: Part 1 overview of the fisheries resources

Book Description
In 1996 the World Bank Operations Evaluation Department completed an internal review of 50 large dams funded by the World Bank. IUCN-The World Conservation Union and the World Bank agreed to jointly host a workshop in April 1997 to discuss the findings of the review and their implications for a more in-depth study. The workshop broke new ground by bringing together representatives from governments, the private sector, international financial institutions and civil society organizations to address three issues: critical advances needed in knowledge and practice, methodologies and approaches required to achieve these advances, and proposals for a follow-up process involving all stakeholders.
