Landscapes are frequently seen as fragments of natural habitat surrounded by a 'sea' of agriculture. But recent ecological theory shows that the nature of these fragments is not nearly as important for conservation as is the nature of the matrix of agriculture that surrounds them. Local extinctions from conservation fragments are inevitable and must be balanced by migrations if massive extinction is to be avoided. High migration rates only occur in what the authors refer to as 'high quality' matrices, which are created by alternative agroecological techniques, as opposed to the industrial monocultural model of agriculture. The authors argue that the only way to promote such high quality matrices is to work with rural social movements. Their ideas are at odds with the major trends of some of the large conservation organizations that emphasize targeted land purchases of protected areas. They argue that recent advances in ecological research make such a general approach anachronistic and call, rather, for solidarity with the small farmers around the world who are currently struggling to attain food sovereignty.Nature's Matrix proposes a radically new approach to the conservation of biodiversity based on recent advances in the science of ecology plus political realities, particularly in the world's tropical regions.

Campesino a Campesino tells the inspiring story of a true grassroots movement: poor peasant farmers teaching one another how to protect their environment while still earning a living. The first book in English about the farmer-led sustainable agriculture movement in Latin America, Campesino a Campesino includes lots of first-person stories and commentary from the farmer-teachers, mixing personal accounts with detailed analysis of the political, socioeconomic, and ecological factors that galvanized the movement. Campesino farmer leading a farmer to farmer training session in Mexico by Eric Holt-GimenezMany years ago, author Eric Holt-Gim�nez was a volunteer trying to teach sustainable agriculture techniques in the dusty highlands of central Mexico, with little success. Near the end of his tenure, he invited a group of visiting Guatemalan farmers to teach a course in his village. What he saw was like nothing he had known. The Guatemalans used parables, stories, and humor to present agricultural improvement to their Mexican compadres as a logical outcome of clear thinking and compassion; love of farming, of family, of nature, and of community. Rather than try to convince the Mexicans of their innovations, they insisted they experiment new things on a small scale first to see how well they worked. And they saw themselves as students, respecting the Mexicans' deep, lifelong knowledge of their own particular land and climate. All they asked in return was that the Mexicans turn around and share their new knowledge with others--which they did. CAC campo3_photo by Food FirstThis exchange was typical of a grassroots movement called Campesino a Campesino, or Farmer to Farmer, which has grown up in southern Mexico and war-torn Central America over the last three decades. In the book Campesino a Campesino, Holt-Gim�nez writes the first history of the movement, describing the social, political, economic, and environmental circumstances that shape it. The voices and stories of dozens of farmers in the movement are captured, bringing to vivid life this hopeful story of peasant farmers helping one another to farm sustainably, protecting their land, their environment, and their families' future.

In Territories of Difference, Arturo Escobar, author of the widely debated book Encountering Development, analyzes the politics of difference enacted by specific place-based ethnic and environmental movements in the context of neoliberal globalization. His analysis is based on his many years of engagement with a group of Afro-Colombian activists of Colombia’s Pacific rainforest region, the Proceso de Comunidades Negras (PCN). Escobar offers a detailed ethnographic account of PCN’s visions, strategies, and practices, and he chronicles and analyzes the movement’s struggles for autonomy, territory, justice, and cultural recognition. Yet he also does much more. Consistently emphasizing the value of local activist knowledge for both understanding and social action and drawing on multiple strands of critical scholarship, Escobar proposes new ways for scholars and activists to examine and apprehend the momentous, complex processes engulfing regions such as the Colombian Pacific today. Escobar illuminates many interrelated dynamics, including the Colombian government’s policies of development and pluralism that created conditions for the emergence of black and indigenous social movements and those movements’ efforts to steer the region in particular directions. He examines attempts by capitalists to appropriate the rainforest and extract resources, by developers to set the region on the path of modernist progress, and by biologists and others to defend this incredibly rich biodiversity “hot-spot” from the most predatory activities of capitalists and developers. He also looks at the attempts of academics, activists, and intellectuals to understand all of these complicated processes. Territories of Difference is Escobar’s effort to think with Afro-Colombian intellectual-activists who aim to move beyond the limits of Eurocentric paradigms as they confront the ravages of neoliberal globalization and seek to defend their place-based cultures and territories.

Biological control is among the most promising methods for control of pests, diseases and weeds, and this book treats ecological and societal aspects together for the first time. The aim is to evaluate the significance of certain biological properties like biodiversity and natural habitats. In a societal approach terms like ‘consumer’s attitude’, ‘risk perception’, ‘learning and education’ and ‘value triangle’ are recognized as significant for biological production and human welfare.

Ob in Europa oder Nordamerika - ländliche Gemeinden kämpfen in den Industriestaaten überall mit ähnlichen Problemen: Der Niedergang der landwirtschaftlichen Familienbetriebe durch technologieintensive Bewirtschaftung führt zur Abwanderung der Bevölkerung in die Städte. In diesem Buch findet nicht nur der Politiker oder Städteplaner Anregungen, wie die Attraktivität der Kleinstädte wieder gesteigert werden kann. Ausführlich werden spezielle Aspekte von Vorstädten und Nahtzonen zwischen Großstadt und Land diskutiert.

Blueprint 3 is the direct sequel to the ground-breaking Blueprint for a Green Economy. Taking the argument much further, David Pearce and his colleagues show how progress towards sustainability in the UK can be measured. They set out the conditions for sustainable development and the measures of economic progress these imply, before looking in detail at all the main areas of economic activity to which the measures are applicable. The result is a wide-ranging and cogent critique of existing policies which also offers new options - options which will require far-reaching reform of this country's existing political and institutional structure. Blueprint 3 will be a touchstone for future discussions of all the major policy areas.

Disease Resistance in Plants, Second Edition, looks at genetic, epidemiologic, biochemical, and biometric principles for developing new cultivars possessing genetic resistance to diseases. It examines the nature of disease resistance and resistance genes, and it highlights the importance of stabilizing selection, sugar, biotrophy, and necrotrophy to obtain the greatest possible yields. Organized into 17 chapters, this volume begins with an overview of disease resistance in plants and the ways to develop disease-resistant variants. It then discusses unspecific resistance; the resistance gene paradox; susceptibility and resistance within narrow host taxa; phenotypic variation and gene numbers in host plants; discontinuous variation and cytoplasmic inheritance; and experimental difficulties in partitioning variance. The reader is also introduced to epistasis and the structure of virulence in pathogens; the notion of physiological race; how the pathogen adapts to the host; mutation in the pathogen from avirulence to virulence; horizontal and vertical resistance to disease and its epidemiological effects; and the link between protein polymorphism and vertical resistance. In addition, the book discusses genes for susceptibility in the host versus genes for avirulence (or virulence) in the pathogen; sink-induced loss of resistance; high-sugar disease processes and biotrophy; slow rusting of cereal crops; plant resistance against endemic disease; and the accumulation of resistance genes in heterogeneous host populations. This book will be useful to plant pathologists and plant breeders.
