This book was released on 2001-07-30 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: En respuesta a la preocupacion general de que la calidad de la tierra para la agricultura se esta gradualmente deteriorando y de que solo hay datos esporadicos disponibles tanto sobre el estado de su calidad o para asistir a los agricultores y a los ejecutivos a mejorar sus estrategias, esta publicacion sugiere oportunidades para hacer un mejor uso de la informacion sobre recursos naturales para la agricultura sostenible. Los indicadores de la calidad de la tierra ofrecen una forma de supervisar y responder a los cambios en los agroecosistemas. Las distintas clases de indicadores ambientales, sociales y economicos necesarias son diferentes a nivel de la finca, de la aldea, del distrito y nacionales, y los indicadores genericos tienen una utilidad limitada a nivel local. El informe tambien trata del manejo e interpretacion de datos e informacion para elaborar, probar y aplicar los indicadores en los paises y esboza el trabajo que se necesita realizar en este ambito en el futuro."

Download or read book Fire Ants And Leaf cutting Ants written by Clifford S. Lofgren and published by CRC Press. This book was released on 2019-03-08 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1985 Research Conference on Fire Ants and Leaf-Cutting Ants covered the most recent developments in research and control of these insect pests of the New World tropical and subtropical zones, the southern United States, South and Central America, and the Caribbean Islands. This volume contains chapters that discuss the history and economics, biology and ecology, behavior, pheromones and other semiochemicals, physiology, and biochemistry of fire ants and leaf-cutting ants, as well as current and future control strategies. The information provided illustrates past and present agricultural and medical problems associated with these pest ants; however, it also brings out the point that they may at times be beneficial. The chapters on basic aspects of the biology and ecology of the ants provide up-to-date information that is useful for a more complete understanding of their social behavior and the unique symbiotic relationship between leaf-cutting ants and their fungi. New approaches to control are illustrated by innovative research on anti-feedant chemicals from plants that prevent feeding by leaf-cutting ants. The present status of chemical baits and biocontrol is addressed, as well as the possibilities of future novel methods based on the use of anti-metabolites, insect hormones, behavior modifying substances, and species-specific toxic bait systems to create integrated pest management systems.

Download or read book Changing Landscapes An Ecological Perspective written by Izaak S. Zonneveld and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landscape Ecology is an emerging science of gaining momentum over the past few decades in the scientific as well as in the planning-management worlds. Although the field is rooted in biology and geography, the approaches to understanding the ecology of a landscape are highly divers. This hybrid vigor provides power to the field. One can no longer view a local ecosystem or land use in isolation from global areas and time frames. The surrounding landscape mosaic and the flows and movements in a landscape must be considered, especially the linkage between humans requiring resources provided by nature, the constraints on their use as well as the responding landscape.

Download or read book Soil Quality for Crop Production and Ecosystem Health written by E.G. Gregorich and published by Elsevier. This book was released on 1997-11-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.

Download or read book Landscape Ecology written by Zev Naveh and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the preface to the softcover edition of this book in 1989, we stated: Since the publication of the first edition of this book, landscape ecology has made great strides. It has overcome its continental isolation and has also established itself in the English-speaking world. By attracting both problem inquiry and problem-solving-oriented scientists with different cultural, academic, and profes sional backgrounds from all over the world, it has broadened not only its geo graphical but also its conceptual and methodological scopes. We are pleased to confirm in 1993 that the growth of landscape ecology continues, and to again express our gratification at the encouraging re sponse to this first English-language monograph on the subject and its contribution to these developments. As before, we feel special satisfac tion that it has reached not only the shelves of libraries and academic re searchers, but that it has also appealed to professional practitioners, teachers, and their students from industrialized and developing countries, embracing the broad range of fields related to landscape ecology in the natural sciences as well as in the humanities.

Download or read book Banana Genomics and Transgenic Approaches for Genetic Improvement written by Sukhada Mohandas and published by Springer. This book was released on 2016-09-08 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bananas and plantains are among the most important food and cash crops in the world. They are cultivated in more than 135 countries, across the tropics and subtropics, with an annual global production of ca. 130 million metric tonnes. Though bananas are one of the most important components of food security in many developing countries, banana production is threatened by both abiotic and biotic stresses. These include a wide range of diseases and pests, such as bunchy top virus, burrowing nematodes, black Sigatoka or black leaf streak, Fusarium wilt, etc. In recent years, considerable progress has been made and several biotechnological and genomic tools have been employed to help understand and unravel the mysterious banana genome. Molecular and genomic studies have helped to decipher the Musa genome and its evolution. Genetic linkage map and whole genome sequencing of both Musa acuminata and Musa balbisiana (progenitors of cultivated banana) have completely changed the way of thinking and the approach on banana crop improvement. Whole-genome sequencing has helped to improve the selection of quantitative traits such as yield, as well as the selection of optimal parents for developing required hybrids in breeding programs. Gene isolation and the analysis of mutants have helped in the characterization of genes of agronomic value and the associated regulatory sequences. With the advent of molecular markers and new statistical tools, it is now possible to measure the diversity, identify genes and useful alleles linked to important agronomic traits. Further these alleles can be incorporated into cultivars through marker assisted selection or through transgenic approach. Transgenic approaches are potential tools for direct transfer of these genes into popular cultivars, which are generally not amenable for conventional breeding techniques, in specific with crops such as bananas which are sterile, triploid and heterozygous thereby making it difficult to reconstruct the recurrent genotypes in banana. Transgenic techniques thus have helped overcome the difficulty of working with sterile, triploid banana crop. In the last five years, enormous amount of new information and techniques have been generated for banana. A comprehensive book entitled “Banana: Genomics and Transgenic Approaches for Genetic improvement” on banana genomics, latest transgenic technologies and tools available for improved crop development in banana will address all these requirements.

Download or read book Temperate Agroforestry Systems written by Andrew M Gordon and published by CABI. This book was released on 2018-03-07 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic animal production has increased rapidly in recent years to keep up with the increasing consumer demand for organic meats. There are many guidelines and restrictions on what should go into the feedstuffs of organically farmed animals, from which difficulties arise when trying to ensure a well-balanced, nutritious diet without the use of any supplements. The book has been completely updated and revised to address how to formulate organic diets in situations where there is a declining supply of organic feed, as well as the feasibility of utilizing novel feedstuffs and their acceptability by consumers of organic meat products. Including the experiences of producers in relation to appropriate breeds and production systems for forage-based organic production, this book is an important read for researchers and students of organic food animal production, veterinary sciences and food; as well as food industry personnel and organic farmers.

Download or read book The Vertical Farm written by Dickson Despommier and published by Macmillan. This book was released on 2010-10-12 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The vertical farm is a world-changing innovation whose time has come. Dickson Despommier's visionary book provides a blueprint for securing the world's food supply and at the same time solving one of the gravest environmental crises facing us today."--Sting Imagine a world where every town has their own local food source, grown in the safest way possible, where no drop of water or particle of light is wasted, and where a simple elevator ride can transport you to nature's grocery store - imagine the world of the vertical farm. When Columbia professor Dickson Despommier set out to solve America's food, water, and energy crises, he didn't just think big - he thought up. Despommier's stroke of genius, the vertical farm, has excited scientists, architects, and politicians around the globe. Now, in this groundbreaking book, Despommier explains how the vertical farm will have an incredible impact on changing the face of this planet for future generations. Despommier takes readers on an incredible journey inside the vertical farm, buildings filled with fruits and vegetables that will provide local food sources for entire cities. Vertical farms will allow us to: - Grow food 24 hours a day, 365 days a year - Protect crops from unpredictable and harmful weather - Re-use water collected from the indoor environment - Provide jobs for residents - Eliminate use of pesticides, fertilizers, or herbicides - Drastically reduce dependence on fossil fuels - Prevent crop loss due to shipping or storage - Stop agricultural runoff Vertical farms can be built in abandoned buildings and on deserted lots, transforming our cities into urban landscapes which will provide fresh food grown and harvested just around the corner. Possibly the most important aspect of vertical farms is that they can built by nations with little or no arable land, transforming nations which are currently unable to farm into top food producers. In the tradition of the bestselling The World Without Us, The Vertical Farm is a completely original landmark work destined to become an instant classic.
