Constraints on the availability of freshwater and land plants and animals to feed the 9.2 billion humans projected to inhabit Earth by 2050 can be overcome by enhancing the contribution the ocean makes to food production. Catches from ocean fisheries are unlikely to recover without adequate conservation measures, so the greater contribution of the oceans to feeding humanity must be derived largely from mariculture. For the effort to be successful, mariculture must close the production cycle to abandon its current dependence on fisheries catches; enhance the production of edible macroalgae and filter-feeder organisms; minimize environmental impacts; and increase integration with food production on land, transferring water-intensive components of the human diet (i.e., production of animal protein) to the ocean. Accommodating these changes will enable the oceans to become a major source of food, which we believe will constitute the next food revolution in human history.

This edited volume presents and reflects upon empirical evidence of 'sustainability'-induced and -related transition in food practices. The material collected in the various chapters contributes to our understanding of the ways in which ideas and preferences, sociotechnological developments and changes in the governance of food interact and become visible in practices of consumption, retail and production.

Food is increasingly traded internationally, thereby transforming the organization of food production and consumption globally and influencing most food-related practices. This transition is generating unfamiliar challenges related to sustainability of food provision, the social impacts of international trade and global food governance. Distance in time and space between food producers and consumers is increasing and new concerns are arising. These include the environmental impact of food production and trade, animal welfare, the health and safety of food and the social and economic impact of international food trade. This book provides an overview of the principal conceptual frameworks that have been developed for understanding these changes. It shows how conventional regulation of food provision through sovereign national governments is becoming elusive, as the distinctions between domestic and international, and between public and private spheres, disappear. At the same time multi-national companies and supranational institutions put serious limits to governmental interventions. In this context, other social actors including food retailers and NGOs are shown to take up innovative roles in governing food provision, but their contribution to agro-food sustainability is under continuous scrutiny. The authors apply these themes in several detailed case studies, including organic, fair trade, local food and fish. On the basis of these cases, future developments are explored, with a focus on the respective roles of agricultural producers, retailers and consumers.

Quantitative risk assessment of Bacillus cereus using data from pasteurised milk produced in Slovakia was performed. Monte Carlo simulations were used for probability calculation of B. cereus density at the time of pasteurised milk consumption for several different scenarios. The results of the general case exposure assessment indicated that almost 14% of cartons can contain 104 CFU/ml of B. cereus at the time of pasteurised milk consumption. Despite the absence of a generally applicable dose-response relationship that limits a full risk assessment, the probability of intoxication per serving and the estimated number of cases in the population were calculated for the general exposure assessment scenario using an exponential dose-response model based on Slovak data. The mean number of annual cases provided by the risk assessment model for pasteurised milk produced in Slovakia was 0.054/100 000 population. In comparison, the overall reporting rate of the outbreaks in the EU in which B. cereus toxins were the causative agent was 0.02/100 000 population in 2010. Our assessment is in accordance with a generally accepted fact that reporting data for alimentary intoxication are underestimated, mostly due to the short duration of the illness.

Food and food markets still enjoy a pivotal role in the world economy and the international food industry is moving towards greater consolidation and globalization, with increased vertical integration and changes to market structure. Companies grow bigger in order to obtain economies of scale and issues and such as food security, quality, obesity and health are ever important factors. This book describes the link between food markets and food companies from a theoretical and a business economics perspective. The relationships, trends and impacts on the international food market are presented, and the topic is related to actual business conditions. Each chapter is accompanied by questions and assignments designed to help students in their learning.

We estimated the ecological footprint of cities in Baltic Europe and globally. The 29 largest cities of Baltic Europe appropriate for their resource consumption and waste assimilation an area of forest, agricultural, marine, and wetland ecosystems that is at least 565-1130 times larger than the area of the cities themselves. Of the global human population, 20% (1.1 billion), living in 744 large cities worldwide, appropriate for their seafood consumption as much as 25% of the globally available area of productive marine ecosystems. The same cities' appropriation of forests for assimilation of CO2emissions exceeds the full sink capacity of the world's forests by more than 10%. If the goal as emphasized at the UN Habitat II Conference, 1996, is sustainable human settlements, the increasingly limited capacity of ecosystems to sustain urban areas has to be explicitly accounted for in city planning and development.

Political Agroecology is the first book to offer a systematic and articulated reflection on Political Agroecology from the Agroecological perspective. It defines the disciplinary field responsible for designing and producing actions, institutions and regulations aimed at achieving agrarian sustainability. In short, it aims to build a political theory that makes the scaling-up of agroecological experiences possible, turning them into the foundation of a new and alternative food regime. The book proposes theoretical, practical and epistemological foundations of a new theoretical and practical field of work for agroecologists: Political Agroecology . It establishes a framework for a common agroecological strategy, covering the different levels of collective action and the different instruments with which it can be developed. This will be essential reading for agroecologists, environmentalists, farming and food communities, and an ideal textbook for advanced agroecology courses in universities. Key features: Offers a unique state of the art on this fundamental new topic: Political Agroecology Presents a complete introduction to the political and institutional aspects of Agroecology, covering the whole food system Offers an important tool for searching agrarian sustainability Provides a broad epistemological, theoretical and methodological focus, exploring the connection between the different levels and scales involved in agroecological theory and practice 　 Manuel González de Molina Full Professor of Modern History.

Boosting the water productivity of world agriculture will be crucial in meeting the food needs in the future. Scientific research has led to improvements in agricultural productivity, but water constraints remain a problem.
