The overutilization of fish stocks, the overcapitalization of fisheries, the removal of associated benefits to society and growing concern over the conservation of marine biodiversity have resulted in a line of fisheries research that is multidisciplinary, dynamic and precautionary in approach. All the biological, ecological and economic factors need to be analysed if the forces regulating the dynamics of a fishery are to be appraised. This publication looks at the assumptions underlying the optimal allocation of renewable natural resources; lists the bioeconomic points of reference resulting from analysis of fisheries is supposed conditions of equilibrium; analysis bioeconomic models according to ecological interdependence factors (such as competition and predation) and technological factors (such as competition between fleets with different fishing capacity); offers a time-series analysis of fisheries and estimates the level of optimal effort; proposes mathematical models applied to bioeconomic analysis to support fisheries management plans; refutes the assumption of uniform resource distribution, incorporating a spatial dimension in fisheries dynamics analysis; and expounds basic elements of decision-making theory and criteria that reflect different attitudes to risk aversion in fisheries management.

In the past six years, the world's fishery sector has reached a turning point with global fish production reaching a plateau of approximately 100 million tons annually. While aquaculture output continued to grow, yields from capture fisheries were uneven and showed increasing signs of stagnation because of widespread overfishing and overcapitalization, ineffective management, deteriorating resource health, declining or flat global harvests, and inefficient economic and trade policies. This paper examines the role of subsidies in fisheries.

Living Marine Resources provides a thorough, up-to-date introduction to all aspects of fisheries science. This clearly written text offers insight into a topic of increasing importance--the wise utilization and management of sea fisheries to maximize production without exceeding their carrying capacity. Adoption of the approaches presented will improve the conservation and management of the many world fisheries that are suffering from years of inefficient practices. The book is divided into five sections, beginning with an introduction to the ocean environment and the various resource species. Part two examines fisheries biology, including age, growth, fecundity, and mortality, enabling readers to appreciate yield models designed to give estimates of maximum sustainable yield and maximum economic yield. The third part covers gear, methods, and landings and includes material on the handling and processing of seafood as well as aquaculture. In part four, yield models are presented to introduce students to theories on population dynamics, stock assessment, and management. The book concludes with coverage of recreational fisheries, including socioeconomic importance, catch and effort research, management techniques, and their interface with commercial fisheries. Living Marine Resources is an invaluable introduction to the subject for advanced undergraduate and graduate students of fisheries science. In addition, the material presented will be valuable to fishery and social scientists, fishery officers and administrators, and students in biology, engineering, economics, and law.

This report addresses the most important challenges facing the Latin America and Caribbean region as it attempts to replace its traditional economic and social structures, including populist institutions, with a modern, efficient, administrative state. The analysis focuses on the political economy of pending reforms and their ramifications. The report discusses (1) recent economic and political developments; (2) systemic issues such as high real interest and unemployment rates and declining export growth; (3) social policies and the need to consolidate macroeconomic stability; and (4) how to define and build the new Latin American state. An appendix provides detailed information on selected country performance.

With external financial help and advice, Poland has made great strides toward sustainable growth. The country's currency is stable, its international creditworthiness has been restored, and its private sector now accounts for two-thirds of GDP. This review evaluates the overall relevance, efficacy, and efficiency of World Bank assistance to Poland and finds that the Bank's technical advice and intellectual support were pivotal in facilitating the work of Polish reformers. The book explores various stages in the evolution of the Bank's assistance to Poland: systemic and institutional transformation and social improvement; private sector and infrastructure development; implementation and supervision; and, results and recommendations. Boxes, figures, and tables illustrate the Bank's assistance strategy, including information on the distribution of Bank resources among Central Eastern and European countries, total Bank commitments to Poland by fiscal year, and a summary of the strengths and weaknesses of Bank assistance to Poland.

During the last decade, there has been a shift in the governance and management of fisheries to a broaderapproach that recognizes the participation of fishers, local stewardship, and shared decision-making.Through this process, fishers are empowered to become active members of the management team,balancing rights and responsibilities, and working in partnership with government. This approach iscalled co-management.This handbook describes the process of community-based co-management from its beginning, throughimplementation, to turnover to the community. It provides ideas, methods, techniques, activities, checklists,examples, questions and indicators for the planning and implementing of a process of community-basedco-management. It focuses on small-scale fisheries (freshwater, floodplain, estuarine, or marine) indeveloping countries, but is also relevant to small-scale fisheries in developed countries and to themanagement of other coastal resources (such as coral reefs, mangroves, sea grass, and wetlands). Thishandbook will be of significant interest to resource managers, practitioners, academics and students ofsmall-scale fisheries.

This booklet examines the efforts of Bangladesh, Malawi, and Pakistan to increase the number of girls in school. These three countries have severe problems of access to education, ranking in the bottom third of developing countries on UNESCO's Basic Education Index. The document addresses several issues, including how governments grapple with the deep-seated cultural, institutional, and political factors that underlie the gender disparity in access to school, how parents and communities feel about these attempts, and what impact the reform efforts have on the people involved in managing and running the school system. It also follows the lives of some of the girls who have benefited from the reforms.
