Download or read book Man and River Systems written by Josselin Garnier and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume focuses on the ecological functioning of rivers, which has received less attention than functioning of lakes and reservoirs. The selected papers cover a large range of topics relating to aquatic communities, eutrophication, nutrient dynamics and organic pollution, erosion and sediment transport, and fate of micropollutants at the basin scale. Integrated approaches developed in order to study the ecological functioning of fluvial systems perturbed by human activity are presented. This functioning is analysed from the point of view of fundamental research, but insights into system management are not neglected. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, and water surface pollution, to postgraduate students, to the institutions involved in water resource management, and to the drinking water and waste water treatment industries. It draws information from many large river systems in the world.

Download or read book Agriculture in Urban Planning written by Mark Redwood and published by Earthscan. This book was released on 2012 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, by graduate researchers working in urban agriculture, examines concrete strategies to integrate city farming into the urban landscape. Drawing on original field work in cities across the rapidly urbanizing global south, the book examines the contribution of urban agriculture and city farming to livelihoods and food security. Case studies cover food production diversification for robust and secure food provision; the socio-economic and agronomic aspects of urban composting; urban agriculture as a viable livelihood strategy; strategies for integrating city farming into urban landscapes; and the complex social-ecological networks of urban agriculture. Other case studies look at public health aspects including the impact of pesticides, micro-biological risks, pollution and water contamination on food production and people. Ultimately the book calls on city farmers, politicians, environmentalists and regulatory bodies to work together to improve the long term sustainability of urban farming as a major, secure source of food and employment for urban populations.

Available in PDF, EPUB and Kindle. Book excerpt: INVASIVE ALIEN SPECIES Invasive Alien Species: Observations and Issues from Around the World Volume 1: Issues and Invasions in Africa Invasive alien species are spreading into new ecosystems each year. The impacts caused by these invaders can be swift and devastating. The topic of invasive alien species is large, complex, and globally significant at various scales, exacerbated by the globalization of world economies and increased trade and commerce that has overcome natural barriers to species movement. Invasive alien species threaten global food supplies, water quality and availability, and energy production and delivery. With the added risks associated with global climate change, the global homogenization of plants, animals, and microbes is a major factor in the decline in ecosystem health and ecosystem services worldwide. To counter this trend, there is a critical need to unify governments, cultures, and programs to improve cross-boundary coordination to effectively address the wide range of invasive alien species threats to the environment, economies, and to plant and animal health; particularly human health. This 4-volume work is the first to compile a set of useful material for key topics, to provide a better understanding of the overall global threat of invasive alien species and the diverse array of problems faced around the world, and assemble material that includes potential replicable solutions to overcome these threats. The books also highlight the threat posed by invasive alien species in terms of a global ‘call to action’. Since invasive species know no boundaries, it is our hope that by compiling material from different scientific and social perspectives around the world, and sharing knowledge and examples of a diverse array of associated topics, we can advance global awareness and improve unified national responses to the threat posed by invasive alien species.

Download or read book The Evolution of Primary Sexual Characters in Animals written by Janet Leonard and published by Oxford University Press. This book was released on 2010-07-16 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primary sexual traits, those structures and processes directly involved in reproduction, are some of the most diverse, specialized, and bizarre in the animal kingdom. Moreover, reproductive traits are often species-specific, suggesting that they evolved very rapidly. This diversity, long the province of taxonomists, has recently attracted broader interest from evolutionary biologists, especially those interested in sexual selection and the evolution of reproductive strategies. Primary sexual characters were long assumed to be the product of natural selection, exclusively. A recent alternative suggests that sexual selection explains much of the diversity of "primary" sexual characters. A third approach to the evolution of reproductive interactions after copulation or insemination has been to consider the process one of sexual conflict. That is, the reproductive processes of a species may reflect, as does the mating system, evolution acting on males and on females, but in different directions. In this volume, authors explore a wide variety of primary sexual characters and selective pressures that have shaped them, from natural selection for offspring survival to species-isolating mechanisms, sperm competition, cryptic female choice and sexual arms races. Exploring diverse reproductive adaptations from a theoretical and practical perspective, The Evolution of Primary Sexual Characters will provide an unparalleled overview of sexual diversity in many taxa and an introduction to the issues in sexual selection that are changing our view of sexual processes.

Available in PDF, EPUB and Kindle. Book excerpt: Qu'entend-on exactement par l'agroécologie ? Quels sont les acteurs qui la défendent, la conçoivent, la mettent en oeuvre ? Et si elle est aujourd'hui évoquée sur tous les continents, l'est-elle finalement dans les mêmes termes, et soulève-t-elle les mêmes débats partout dans le monde ? L'ambition de cet ouvrage est de mettre en regard autour de ces questions les situations de deux grands pays agricoles, dans lesquels l'agroécologie a connu récemment d'importants développements : l'Argentine et la France.

Download or read book Campesino a Campesino written by Eric Holt-Giménez and published by Food First Books. This book was released on 2006 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Good beekeeping practices for sustainable apiculture written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-09-21 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bees provide a critical link in the maintenance of ecosystems, pollination. They play a major role in maintaining biodiversity, ensuring the survival of many plants, enhancing forest regeneration, providing sustainability and adaptation to climate change and improving the quality and quantity of agricultural production systems. In fact, close to 75 percent of the world’s crops that produce fruits and seeds for human consumption depend, at least in part, on pollinators for sustained production, yield and quality. Beekeeping, also called apiculture, refers to all activities concerned with the practical management of social bee species. These guidelines aim to provide useful information and suggestions for a sustainable management of bees around the world, which can then be applied to project development and implementation.

Download or read book Agroecological Transitions From Theory to Practice in Local Participatory Design written by Jacques-Eric Bergez and published by Springer. This book was released on 2019-02-28 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Open Access book presents feedback from the ‘Territorial Agroecological Transition in Action’- TATA-BOX research project, which was devoted to these specific issues. The multidisciplinary and multi-organisation research team steered a four-year action-research process in two territories of France. It also presents: i) the key dimensions to be considered when dealing with agroecological transition: diversity of agriculture models, management of uncertainties, polycentric governance, autonomies, and role of actors’ networks; ii) an operational and original participatory process and associated boundary tools to support local stakeholders in shifting from a shared diagnosis to a shared action plan for transition, and in so doing developing mutual understanding and involvement; iii) an analysis of the main effects of the methodology on research organisation and on stakeholders’ development and application; iv) critical analysis and foresights on the main outcomes of TATA-BOX, provided by external researchers.
