European Landraces

National policies to support the conservation and use of landraces in production systems for sustainable agriculture.

Based on the 2010 conference "Towards the establishment of genetic reserves for crop wild relatives and landraces in Europe", this book is the cutting edge discussion of agrobiodiversity conservation. By considering the benefits of understanding and preserving crop wild relatives and landraces, it encompasses issues as wide-ranging and topical as habitat protection, ecosystem health and food security. Focusing on Europe, but globally relevant, Agrobiodiversity Conservation is ideal for postgraduate students of conservation and environmental studies, conservation professionals, policy makers and researchers.

Local landraces are traditional crop varieties cultivated in specific locations. However, the intensification of modern horticulture has put these genotypes aside, since farmers tend to select hybrids or commercial cultivars due to higher yield, uniformity and marketability. The various landraces are very distinct in their quality features, therefore it is of high importance to highlight these differences and identify genotypes that could be further exploited by producing high added value products and by reinforcing local rural economies. The proposed Research Topic aims to reveal the importance of local landraces for sustainable horticulture, focusing on their special quality features as the result of adaptation to specific growing conditions after domestication.

Landraces possess a very large genetic base in population structure and are dynamic populations of cultivated plants with historical origin, distinct identity, and without any formal crop improvement. They are often genetically diverse, locally adapted, and associated with traditional farming systems. Resistance genes to biotic and abiotic stress factors, which are especially diversified in landraces, are of great interest to plant breeders, faced with global climate challenge. In addition, gene pools made of different landraces grown in different ecological conditions can be used for wheat breeding to enhance quality; yield and other desirable agricultural parameters. An estimated 75% of the genetic diversity of crop plants was lost in the last century due to the replacement of high yielding modern varieties. There is, thus, an urgent need to preserve existing species, not only for posterity but also as a means to secure food supply for a rising world population. In this book, we provide an overview of wheat landraces with special attention to genetic diversities, conservation, and utilization.

Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. It is a discipline that addresses current issues: climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control and biodiversity depletion. This series gathers review articles that analyze current agricultural issues and knowledge, then proposes alternative solutions.

In recent years, all over the world, the attention paid to local and traditional productions is growing, especially in the agro-food sector. Maybe, it is not only due to the impact of globalization and the social and economic changes but also due to the increased consideration to health and nutritional aspects of food. Hence, for economic, social, historical, and nutritional reasons, this trend has led to the rediscovery and reuse of landraces of many different crops, responding to requests for more and more demanding market. This volume collects examples of local crops and old landraces of different areas of the planet that testify the extreme importance of the relation existing among a land, the local productions, the historical traditions, the conservation of biodiversity, the health benefits, the environmental impact and the local economies, also including the significance to dedicate resources to scientific researches in local crops.

“An essential read for anyone interested in the stories of the animals in our home or on our plate.”—BBC Focus Without our domesticated plants and animals, human civilization as we know it would not exist. We would still be living at subsistence level as hunter-gatherers if not for domestication. It is no accident that the cradle of civilization—the Middle East—is where sheep, goats, pigs, cattle, and cats commenced their fatefully intimate association with humans. Before the agricultural revolution, there were perhaps 10 million humans on earth. Now there are more than 7 billion of us. Our domesticated species have also thrived, in stark contrast to their wild ancestors. In a human-constructed environment—or man-made world—it pays to be domesticated. Domestication is an evolutionary process first and foremost. What most distinguishes domesticated animals from their wild ancestors are genetic alterations resulting in tameness, the capacity to tolerate close human proximity. But selection for tameness often results in a host of seemingly unrelated by-products, including floppy ears, skeletal alterations, reduced aggression, increased sociality, and reduced brain size. It's a package deal known as the domestication syndrome. Elements of the domestication syndrome can be found in every domesticated species—not only cats, dogs, pigs, sheep, cattle, and horses but also more recent human creations, such as domesticated camels, reindeer, and laboratory rats. That domestication results in this suite of changes in such a wide variety of mammals is a fascinating evolutionary story, one that sheds much light on the evolutionary process in general. We humans, too, show signs of the domestication syndrome, which some believe was key to our evolutionary success. By this view, human evolution parallels the evolution of dogs from wolves, in particular. A natural storyteller, Richard C. Francis weaves history, archaeology, and anthropology to create a fascinating narrative while seamlessly integrating the most cutting-edge ideas in twenty-first-century biology, from genomics to evo-devo.
