Book excerpt: In aquaculture, the provision of high quality aquafeeds that satisfy the nutritional requirements of the culture species and optimize growth are a prerequisite to improving production yields, lowering production costs, and improving economic returns to farmers. Under semi-intensive and intensive carp and trout culture, aquafeed costs usually account for the highest single production cost, typically accounting for 50 – 60 percent of total production costs. The aquafeeds available to farmers vary widely with respect to quality, nutritional value and cost. Depending on the feed type, production system and farmer preferences, there are multiple feed management strategies that can be adopted by farmers. In order to optimise feed use and minimise feed production costs, it is essential that farmers select appropriate feeds and optimise their on farm feed management practices. These guidelines are designed to provide farmers with practical guidance on how to select feeds and to optimise their use by implementing appropriate on-farm feed management practices. The guidelines provide an introduction to fish nutrition with a focus on the dietary nutritional requirements of commercially cultured carps and trout. The types of aquafeeds (live feeds, supplementary, farm-made and commercially manufactured feeds), their composition and nutritional value, manufacture and use are discussed. On-farm feed management practices focus on feeding methods, feed storage, and methods to optimise feed consumption (calculating feed rations, feeding frequency, assessing appetite and the feeding response).

Available in PDF, EPUB and Kindle. Book excerpt: Remarkable advances are being made in life science and agricultural research to reform the methods of food production, particularly with regard to staple grain and legume crops, in ways that will better reflect ecological realities. However, advances in science may be insufficient to ensure that these possibilities for agricultural reform are realized in practice and in a sustainable way. This book shows how these can only be achieved through changes in legal norms and institutions at the global level. Interdisciplinary in character, the book draws from a range of issues involving agricultural innovation, international legal history and principles, treaty commitments, global institutions, and environmental challenges, such as climate change, to propose broad legal changes for transforming global agriculture. It first shows how modern extractive agriculture is unsustainable on economic, environmental, and social grounds. It then examines the potential for natural-systems agriculture (especially perennial-polyculture systems) for overcoming the deficiencies of modern extractive agriculture, especially to offset climate change. Finally it analyses closely the legal innovations that can be adopted at national and international levels to facilitate a transition from modern extractive agriculture to a system based more on ecological principles. In particular the author argues for the creation of a Global Convention on Agroecology.

Available in PDF, EPUB and Kindle. Book excerpt: Although there are many studies of certain individual ancient Italic groups (e.g. the Etruscans, Gauls and Latins), there is no work that takes a comprehensive view of each of them—the famous and the less well-known—that existed in Iron Age and Roman Italy. Moreover, many previous studies have focused only on the material evidence for these groups or on what the literary sources have to say about them. This handbook is conceived of as a resource for archaeologists, historians, philologists and other scholars interested in finding out more about Italic groups from the earliest period they are detectable (early Iron Age, in most instances), down to the time when they begin to assimilate into the Roman state (in the late Republican or early Imperial period). As such, it will endeavor to include both archaeological and historical perspectives on each group, with contributions from the best-known or up-and-coming archaeologists and historians for these peoples and topics. The language of the volume is English, but scholars from around the world have contributed to it. This volume covers the ancient peoples of Italy more comprehensively in individual chapters, and it is also distinct because it has a thematic section.

Available in PDF, EPUB and Kindle. Book excerpt: Climate change presents an unprecedented challenge to the productivity and profitability of agriculture in North America. More variable weather, drought, and flooding create the most obvious damage, but hot summer nights, warmer winters, longer growing seasons, and other environmental changes have more subtle but far-reaching effects on plant and livestock growth and development. Resilient Agriculture recognizes the critical role that sustainable agriculture will play in the coming decades and beyond. The latest science on climate risk, resilience, and climate change adaptation is blended with the personal experience of farmers and ranchers to explore: The "strange changes" in weather recorded over the last decade The associated shifts in crop and livestock behavior The actions producers have taken to maintain productivity in a changing climate The climate change challenge is real and it is here now. To enjoy the sustained production of food, fiber, and fuel well into the twenty-first century, we must begin now to make changes that will enhance the adaptive capacity and resilience of North American agriculture. The rich knowledge base presented in Resilient Agriculture is poised to serve as the cornerstone of an evolving, climate-ready food system. Laura Lengnick is a researcher, policymaker, activist, educator, and farmer whose work explores the community-enhancing potential of agriculture and food systems. She directs the academic program in sustainable agriculture at Warren Wilson College and was a lead author of the report Climate Change and Agriculture in the United States: Effects and Adaptation.

This book was released on 2012-10-01 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food is the new oil. Land is the new gold. The world food situation is deteriorating. Grain stocks have dropped to a dangerously low level. The World Food Price Index has doubled in one decade. The ranks of the hungry are expanding; political unrest is spreading. On the demand side of the food equation, there will be 219,000 people at the dinner table tonight who were not there last night. And some 3 billion increasingly affluent people are moving up the food chain, consuming grain-intensive livestock and poultry products. At the same time, water shortages and heat waves are making it more difficult for farmers to keep pace with demand. As grain-exporting countries ban exports to keep their food prices down, importing countries are panicking. In response, they are buying large tracts of land in other countries to grow food for themselves. The land rush is on. Could food become the weak link for us as it was for so many earlier civilizations? Lester Brown, one of the leading environmentalists of our time, explains why world food supplies are tightening and tells what we need to do about it.
