Grassland farming in Europe was already established during the settlement of the rst farmers together with their domesticated animals after the last ice age. Since then, grassland provides the forage basis to feed ruminant animals for the p- duction of meat and milk. Depending on the ecological conditions and intensity of usage, various plant communities with different species developed, displaying a rich biodiversity. With the introduction of improved crop rotations at the end of the 16th century, grasses and legumes were also grown to an important extent as forage crops on arable land. In the last decades the importance of amenity grasses increased markedly, due to the demand of the society for new usages like landscape protection. Around 1900 interested farmers and academics identi ed the need for gra- land improvement through systematic selection and seed production. This marks the beginning of breeding and research in companies but also at universities and specialized research institutes. Plant collection started with many of the species that are still of importance today. The collected materials were grouped according to the intended use and some type of phenotypic selection was applied. Seed mul- plication of such populations was performed in pure stands and the harvested seed was marketed. Although the vegetative biomass and its quality are of utmost imp- tance in forage crop breeding, it is the seed yield potential which determines the commercial success of a new variety.

Do you ever tell yourself that you're not enough? Not smart enough, not rich enough, not good enough, not fill-in-the-blanks enough? Or do you worry that there is not enough: not enough time, not enough money, not enough opportunity, not enough…whatever? Consciously and unconsciously, dozens of times a day, we tell ourselves that we are lacking, that our lives are lacking, that the universe is lacking. We lull ourselves into what Victoria Castle calls the “Trance of Scarcity”—a numbed state in which we're crippled by the pervasive assumption that lack, struggle, and separation are our unavoidable fate. But what if it is the very story we tell ourselves—both as individuals and as a society—that keeps us trapped in this limited state? Here Castle shows you how to embody a new story—one that is about abundance, inspiration, and your own innate ability to create your reality. Once you break free from the Trance of Scarcity, you'll be able to live a more meaningful and fulfilling life.

Sustainable management of the world's livestock genetic diversity is of vital importance to agriculture, food production, rural development and the environment. "The State of the World's Animal Genetic Resources for Food and Agriculture" is the first global assessment of these resources. Drawing on 169 Country Reports, contributions from a number of international organizations and 12 specially commissioned thematic studies, it presents an analysis of the state of agricultural biodiversity in the livestock sector - origins and development, uses and values, distribution and exchange, risk status and threats - and of capacity to manage these resources - institutions, policies and legal frameworks, structured breeding activities and conservation programmes. Needs and challenges are assessed in the context of the forces driving change in livestock production systems. Tools and methods to enhance the use and development of animal genetic resources are explored in sections on the state of the art in characterization, genetic improvement, economic evaluation and conservation. The main findings of the report are summarized in "The State of the World's Animal Genetic Resources for Food and Agriculture - in brief," of which the Arabic, Chinese, English, French, Russian and Spanish versions can be found on the attached CD-ROM and are also available separately in printed form. As well providing a technical reference document, the country-based preparation of "The State of the World" has led to a process of policy development and a "Global Plan of Action for Animal Genetic Resources," which once adopted, will provide an agenda for action by the international community. Published also in French.

This newly updated and revised volume of the Encyclopedia of Sustainability Science and Technology (ESST) details the role of Animal Breeding and Genetics in the sustainability of animal agriculture. The volume covers scientific principles and applications includes the current science used to advance cattle, poultry, swine,sheep, and equine populations, as well as the future role of techniques such as gene editing. International leaders in the field explain foundational concepts such as heritability, the covariance between relatives, statistical approaches to predicting the genetic merit of individuals, and the development and advancement of molecular techniques to elucidate changes in the DNA sequence that underly phenotypic variation. The use of genetic-based tools to improve animal agriculture and meet consumer demands across species is treated in detail. Readers will gain an understanding of how global livestock producers have implemented advanced genetic selection tools and used them to improve reproduction, production, efficiency, health, and sustainability. The interactions of genetics and production environments, and the genetic components of the complex interactions among animals are also discussed. The future of Animal Breeding and Genetics, including the challenges and opportunities that exist in feeding a growing world population, are addressed.

Although aquaculture as a biological production system has a long history, systematic and efficient breeding programs to improve economically important traits in the farmed species have rarely been utilized until recently, except for salmonid species. This means that the majority of aquaculture production (more than 90 %) is based on genetically unimproved stocks. In farm animals the situation is vastly different: practically no terrestrial farm production is based on genetically unimproved and undomesticated populations. This difference between aquaculture and livestock production is in spite of the fact that the basic elements of breeding theory are the same for fish and shellfish as for farm animals. One possible reason for the difference is the complexity of reproductive biology in aquatic species, and special consideration needs to be taken in the design of breeding plans for these species. Since 1971 AKVAFORSK, has continuously carried out large scale breeding research projects with salmonid species, and during the latest 15 years also with a number of fresh water and marine species. Results from this work and the results from other institutions around the world have brought forward considerable knowledge, which make the development of efficient breeding programs feasible. The genetic improvement obtained in selection programs for fish and shellfish is remarkable and much higher than what has been achieved in terrestrial farm animals.

"Peace Ecology" presents a cutting-edge exploration of an emerging paradigm that links the essence of peace and nonviolence with the tenets of ecology and the principles of environmentalism. Looking at issues including food justice, water sharing, climate change, peace zones, and the free economy, this book considers examples and illustrations from around the world where people, communities, and nations are employing the teachings of ecology as a tool for mitigating conflict and promoting peace. "Peace Ecology" presents an integrative perspective that bears directly upon the most pressing issues of our time, constituting both the ecological realm of peace and the peacemaking potential of ecology. The volume examines the rich history, contemporary relevance, and transformative future potential inherent in this dynamic nexus of theory and action. Its overarching aim is no less than moving the current scarcity-conflict paradigm to one of cooperative resource management and, ultimately, toward peaceful coexistence both among ourselves and within the balance of nature.To read the Common Dreams excerpt of "Peace Ecology" Click Here.Talk Nation Radio Interview with Randall Amster and David Swanson here."
