Sustainable Agriculture and Food Security


Book Description

This book describes initiatives and concrete examples on sustainable food production worldwide. In the current world scenario, where nations all over the world are struggling to accomplish the United Nations Sustainable Development Goals and to ensure sustainable patterns for all, this book provides a contribution towards a more comprehensive and interdisciplinary understanding of the cross-cutting issues related to Sustainable Agriculture and Food Security. This interdisciplinary book supports the efforts to engage a commitment from all fields of science, to work together to provide knowledge that could help to address SDG2 (No hunger) and lead to the promotion of quality of life, by means of a more sustainable food production, and improved food security. This book is expected to fill the gap of publications in this field. It gives a special emphasis to a state-of-the-art descriptions of approaches, methods, initiatives and projects from universities, stakeholders, organizations and civil society across the world, regarding cross-cutting issues in sustainable food production. It includes examples of policies and practices case studies, examples of projects, institutional policies, innovative methods and tools and research outputs, which highlight the interdependence between sustainable agriculture and food security issues. It is expected that the “Sustainable Agriculture and Food Security” will make the many benefits of sustainable food production clearer and, inter alia, lead to an increase in the emphasis provided to this central theme.




Freshwater Fisheries Ecology


Book Description

Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.




The Wealth of the Commons


Book Description

We are poised between an old world that no longer works and a new one struggling to be born. Surrounded by centralized hierarchies on the one hand and predatory markets on the other, people around the world are searching for alternatives. The Wealth of the Commons explains how millions of commoners have organized to defend their forests and fisheries, reinvent local food systems, organize productive online communities, reclaim public spaces, improve environmental stewardship and re-imagine the very meaning of "progress" and governance. In short, how they've built their commons. In 73 timely essays by a remarkable international roster of activists, academics and project leaders, this book chronicles ongoing struggles against the private com­moditization of shared resources - often known as market enclosures - while docu­menting the immense generative power of the commons. The Wealth of the Commons is about history, political change, public policy and cultural transformation on a global scale - but most of all, it's about individual commoners taking charge of their lives and their endangered resources. "This fine collection makes clear that the idea of the Commons is fully international, and increasingly fully worked-out. If you find yourself wondering what Occupy wants, or if some other world is possible, this pragmatic, down-to-earth, and unsentimental book will provide many of the answers." - Bill McKibben, author of Deep Economy: The Wealth of Communities and The Durable Future
