Coastal farming and ocean ranching of marine fish, shellfish, crustaceans, and seaweed are a major and growing industry worldwide. In the United States, freshwater aquaculture is rapidly becoming a significant commercial activity; however, marine aquaculture has lagged behind. This book examines the obstacles to developing marine aquaculture in the United States and offers specific recommendations for technology and policy strategies to encourage this industry. The volume provides a wealth of information on the status of marine aquaculture - including comparisons between U.S. and foreign approaches to policy and technology and of the diverse species under culture. "Marine Aquaculture" also describes problems of coordination of regulatory policy among various federal, state, and local government agencies and escalating competition for the use of coastal waters. It addresses environmental concerns and suggests engineering and research strategies for alleviating negative impacts from marine aquaculture operations. ... Read more

Description:
Faced with society's increasing expectations, the Common Agricultural Policy (CAP) review considers environmental management to be an ever more critical criterion in the allocation of farm subsidies. With the goal of evaluating the environmental friendliness of farm practices, France's agricultural research and extension services have built a range of agricultural/environmental diagnostic tools over recent years. The objective of the present paper is to compare the five tools most frequently used in France: IDEA, DIAGE, DIALECTE, DIALOGUE and INDIGO. All the tools have the same purpose: evaluation of the impact of farm practices on the environment via indicators and monitoring of farm management practices. When tested on a sample of large-scale farms in Picardie, the five tools sometimes produced completely different results: for a given farm, the most supposedly significant environmental impacts depend on the tool used. These results lead to differing environmental management plans and raise the question of the methods' pertinence. An analysis grid of diagnostic tools aimed at specifying their field of validity, limits and relevance was drawn up. The resulting comparative analysis enables to define each tool's domain of validity and allows to suggest lines of thought for developing more relevant tools for (i) evaluating a farm's environmental performance and (ii) helping farmers to develop a plan for improving practices within the framework of an environmental management system. ...

Everywhere you look people are more aware of what they eat and where their food comes from. In a cafeteria in Los Angeles, children make their lunchtime food choices at fresh-fruit and salad bars stocked with local foods. In a community garden in New York, low-income residents are producing organically grown fruits and vegetables for their own use and to sell at market. In Madison, Wisconsin, shoppers select their food from a bounty of choices at a vibrant farmers' market. Together at the Table is about people throughout the United States who are building successful alternatives to the contemporary agrifood system and their prospects for the future. At the heart of these efforts are the movements for sustainable agriculture and community food security. Both movements seek to reconstruct the agrifood system-the food production chain, from the growing of crops to food production and distribution-to become more ecologically sound, economically viable, and socially just. Allen describes the ways in which people working in these movements view the world and how they see their place in challenging and reshaping the agrifood system. She also shows how ideas and practices of sustainable agriculture and community food security have already woven their way into the dominant agrifood institutions. Allen explores the possibilities this process may hold for improving social and environmental justice in the American agrifood system.Together at the Table is an important reminder that much work still remains to be done. Now that the ideas and priorities of alternative food movements have taken hold, it is time for the next-even more challenging-step. Alternative agrifood movements must acknowledge and address the deeper structural and cultural patterns that constrain the long-term resolution of social and environmental problems in the agrifood system. ...

Product Description
This committee report, "Sustainability Criteria for Water Resource Systems", addresses the need and challenge to reexamine our approaches to water resources planning and management. Water resource systems need to be able to satisfy the changing demands placed on them, now and on into the future, without system degradation. In order to create these sustainable systems, a more holistic and integrated life-cycle approach to water resources planning, development, and management must take place. Such an approach should lead to plans, facilities, and policies that will be physically, economically, environmentally, ecologically, and socially acceptable and beneficial by current as well as future generations. This document examines many of the major issues and challenges raised by the concept of sustainability applied to water resource system design and management. Various suggested guidelines are reviewed including the extent to which they have been applied in the development and management of water resource systems.Some approaches for measuring and modeling sustainability are outlined, and ways are illustrated in which these measures and models might be used when evaluating designs and operating policies. While this manual focuses on the contributions scientists, engineers, economists, and planners can make, it recognizes that the public stakeholders and their political representatives and institutions must also contribute to efficient and sustainable water management. ...

Product Description
The workshop was held in the context of a decreasing inland capture fisheries and aquaculture production in all of the Central Asian countries. Inland capture fisheries and aquaculture are potentially important sources of food, income and employment for many of them. The workshop aimed to build awareness among policymakers, administrators and representatives of the irrigation and fishery sectors on the need to share information and increase collaboration and review the current status of inland capture fisheries in irrigation systems at the national level in the five Central Asian countries. ...
