The Transition in the Contribution of Living Aquatic Resources to Food Security


Book Description

The fishing industry’s aggressive and expanding search for fish from the sea reached a turning point in 1990. After many years of increasing production, the global marine and inland catch from natural stocks declined from the 1989 peak of about 89 million tons to 85 million tons in 1993. Aquaculture production did not increase enough to meet the shortfall, and total production also fell in 1990 and 199. Present indications are that production from natural stocks will be below the current level in the year 2020; at best, it will maintain its present level. The author addresses five major issues: (1) maximizing the use of aquatic resources; (2) resource management; (3) intensification of fisheries exploitation; (4) integration of fisheries and aquaculture; and (5) the difficult problem of balancing national versus international interests.




Fostering Global Well-being


Book Description

This paper proposes a twenty-first century Agricultural Development Paradigm to respond to unprecedented opportunities provided by worldwide economic reforms and trade liberalization initiatives.




Overcoming Child Malnutrition in Developing Countries


Book Description

Although the percentage of children who are malnourishes has declined in many countries of the developing world in recent years, the absolute number of malnourished children is rising in some regions, particulary in Sub-Saharan Africa. This paper aims to determine which of the various causes of mal nutrition are most important for the developing countries as a whole and by region, thus enabling policymakers to prioritize their investments and make the besy use of available resources to reduce malnutrition now and in coming years.










Coastal Ecosystems


Book Description

This volume incorporates theoretical and practical knowledge through case studies and reviews to serve as a baseline of information for coastal ecosystem research, and discusses the impacts of pollution, industrialisation, agriculture and climate change on coastal ecosystem biogeochemistry and biodiversity. The case studies address the role of coastal ecosystems as a carbon sink which is getting impacted by anthropogenic disturbances. Through this analysis, the book covers various strategies for the conservation and management of coastal ecosystems, considering their unique ecological and biogeochemical attributes and region-specific threats and impacts. The book will be of interest to a wide range of readers including students, researchers and professionals in coastal ecosystem science, coastal pollution, climate change adaptation, biodiversity conservation and environmental management.







The Doubly Green Revolution


Book Description

"The original Green Revolution generated new technologies for farmers, creating food abundance. A second transformation of agriculture is now required - specifically, Gordon Conway argues, a "doubly green" revolution that stresses conservation as well as productivity. He calls for researchers and farmers to forge genuine partnerships in an effort to design better plants and animals.




Reinventing Fisheries Management


Book Description

Judged by a dismaying track record and a consequent downturn in the reputation of fisheries scientists, fisheries management is certainly a candidate for calls for reinvention, with many of the world leaders in this area holding the view that no fishery has ever been properly understood or managed. With fisheries science in a state of flux, this extremely important book seeks a new paradigm that will place this flux of ideas in perspective and help us to choose those that will make fisheries management work. The book was planned at a symposium of over 100 fishery researchers at the Fisheries Centre, University of British Columbia, Vancouver, Canada and is organized into five parts: Why does Fisheries Science Need Reinventing?; New Policies; The Role of the Social Sciences; Ecology; Modelling. Carefully integrated and edited by three of the world's leading fishery scientists, this stimulating book should find a place on the shelves of all fishery scientists throughout the world. It will be an invaluable reference source to those studying fish biology, fisheries and oceanography and all those involved in fisheries policy decisions in government and university research establishments.
