Esta investigacion se ha propuesto indagar cuestiones preliminares a problematicas de indole socioeconomica, cuyos correlatos se materializan en asimetrias de la poblacion, y en un inedito exodo rural. Se trata de exhibir situaciones especiales, que demandan repensar criterios de demarcacion intra-regional, tipo de relevamiento censal y contextualizacion de tecnicas de analisis, compatibles con la percepcion geografica y varios indicadores de calidad de vida. Se destacan problemas de enfoque epistemologico y abordaje metodologico de la Geografia Regional, pretendiendo demostrar diferencias entre la arquitectura estadistica oficial, y otra que incluye tecnicas acordes a un diagnostico afin a las particularidades de cada zona. Mediante un analisis holistico, se presentan problematicas particulares del Noroeste Bonaerense, con raiz en el medio fisico y en los efectos tardios de cambios derivados por el boom sojero pampeano. Asi, a las asimetrias entre renta rural y empobrecimiento de algunos sectores urbanos, se suma su invisibilidad estadistica-jurisdiccional por parte de los organismos oficiales, encargados de aportar datos a varias investigaciones economicas y sociales."

South America is an area of fascination and study for geographers and other scholars from around the world, and its land and people have played important roles in the discovery and distribution of civilizations, resources, and nations for millennia. The region has long stimulated a large amount of research across the many subdisciplines of geography, and Thomas A. Rumney collects, organizes, and presents as many scholarly publications as possible in The Geography of South America: A Scholarly Guide and Bibliography. Every South American nation is included: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, French Guiana, Guyana, Paraguay, Peru, Surinam, Uruguay, and Venezuela. Beginning with an overview of the region as a whole, successive chapters, one per nation, are divided by specific subdisciplines of geography: cultural, social, economic, historical, physical and environmental, political, and urban. Each section is then divided by document type: atlases, books, book chapters, articles from scholarly journals, master’s theses, and doctoral dissertations. Although the majority of entries focus on English-language works, selected entries written in Spanish, French, German, and other languages are also included (with the entry titles translated into English and noted accordingly).

Explore the latest research on biological control! Completely updated for 2004, this new edition examines methods for making agricultural systems less susceptible to insect pests. Containing new findings and reports of strategies, Biodiversity and Pest Management in Agroecosystems, Second Edition will show you how pests can be managed by enhancing beneficial biodiversity using agroecological diversification methods. Biodiversity and Pest Management in Agroecosystems, Second Edition provides you with an essential overview of the role of biodiversity in agriculture and then gets specific, with new and updated information on: the agroecology of pest management plant diversity and pest outbreaks within agroecosystems diversification strategies for pest management how sustainable farming systems are designed You'll also explore: the role of plant diversity on the biology of beneficial insects insect regulation in diverse agroecosystems manipulation of plant diversity in agroecosystems ecological and socioeconomic implications The fact is, many modern agroecosystems are unstable as a consequence of constant human intervention in crop systems which ignore ecological principles. With case studies on a variety of crops and pests, Biodiversity and Pest Management in Agroecosystems, Second Edition explores entomological aspects of agriculture and analyzes the ecological basis for the maintenance of biodiversity. It will familiarize you with the theory and practice of enhancing biological pest control in agricultural systems by managing vegetational diversity via multiple cropping, cover cropping, rotations, and other spatial and temporal designs. With studies on intercropping, cover cropping, weed management, and crop-field border vegetation manipulation, this book covers the effects of these diverse systems on pest population density and the mechanisms underlying pest reduction in polycultures.

It was through control of the shattering of wild seeds that humans first domesticated plants. Now control over those very plants threatens to shatter the world's food supply, as loss of genetic diversity sets the stage for widespread hunger. Large-scale agriculture has come to favor uniformity in food crops. More than 7,000 U.S. apple varieties once grew in American orchards; 6,000 of them are no longer available. Every broccoli variety offered through seed catalogs in 1900 has now disappeared. As the international genetics supply industry absorbs seed companies—with nearly one thousand takeovers since 1970—this trend toward uniformity seems likely to continue; and as third world agriculture is brought in line with international business interests, the gene pools of humanity's most basic foods are threatened. The consequences are more than culinary. Without the genetic diversity from which farmers traditionally breed for resistance to diseases, crops are more susceptible to the spread of pestilence. Tragedies like the Irish Potato Famine may be thought of today as ancient history; yet the U.S. corn blight of 1970 shows that technologically based agribusiness is a breeding ground for disaster. Shattering reviews the development of genetic diversity over 10,000 years of human agriculture, then exposes its loss in our lifetime at the hands of political and economic forces. The possibility of crisis is real; this book shows that it may not be too late to avert it.

Nutrient recycling, habitat for plants and animals, flood control, and water supply are among the many beneficial services provided by aquatic ecosystems. In making decisions about human activities, such as draining a wetland for a housing development, it is essential to consider both the value of the development and the value of the ecosystem services that could be lost. Despite a growing recognition of the importance of ecosystem services, their value is often overlooked in environmental decision-making. This report identifies methods for assigning economic value to ecosystem servicesâ€"even intangible onesâ€"and calls for greater collaboration between ecologists and economists in such efforts.

The evidence is increasingly persuasive. We are changing the way our planet's physical systems work—irrevocably. These changes are global and interconnected and unavoidable. They are upon us already, making it virtually impossible for any modern society to continue its present trajectory of growth. This book provides a penetrating analysis of how we have come to this point, of why science and technology will fail to solve these problems, and of how we as a society must change in order to avoid ecological catastrophe. The scope is broad, the urgency of the message is impossible to ignore.
