This book was released on 1978 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Las finalidades del presente trabajo fueron la realizacion de una revision bibliografica del efecto que tiene el fuego sobre el suelo, la evaluacion del efecto que tiene el fuego sobre la escorrentia, perdida de suelo y algunas de las propriedades quimicas de la "Estacion Experimental Zoquiapan". Tales investigaciones se realizaron a fin de establecer consideraciones respecto a las perdidas de suelo y alteraciones en las propriedades quimicas, que pueden ocurrir como resultado de los incendios forestales y el uso del fuego con propositos de manejo silvicola. Se consideraron cuatro asociaciones vegetales que presentaban un alto riesgo de incendio, en las cuales fue estudiada la escorrentia y perdida de suelo. Ademas, se establecio una parcela de 100x100 m dentro de una asociacion Pinus-Pastizal, lo cual junto con las cuatro asociaciones vegetales anteriores fueron utilizadas para estudiar el efecto quetienen las quemas en las propriedades quimicas de suelo. Los resultados obtenidos indican que la escorrentia y perdida de suelo son variables para cada tipo de asociacion vegetal, siendo mayores en la asociacion vegetal "Pastizal amacollado", observandose quetales perdidas diminuyen en la medida en que se establece la nueva vegetacion del area quemada.
Book Synopsis Tropical Fire Ecology by : Mark Cochrane
Download or read book Tropical Fire Ecology written by Mark Cochrane and published by Springer Science & Business Media. This book was released on 2010-04-11 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tropics are home to most of the world’s biodiversity and are currently the frontier for human settlement. Tropical ecosystems are being converted to agricultural and other land uses at unprecedented rates. Land conversion and maintenance almost always rely on fire and, because of this, fire is now more prevalent in the tropics than anywhere else on Earth. Despite pervasive fire, human settlement and threatened biodiversity, there is little comprehensive information available on fire and its effects in tropical ecosystems. Tropical deforestation, especially in rainforests, has been widely documented for many years. Forests are cut down and allowed to dry before being burned to remove biomass and release nutrients to grow crops. However, fires do not always stop at the borders of cleared forests. Tremendously damaging fires are increasingly spreading into forests that were never evolutionarily prepared for wild fires. The largest fires on the planet in recent decades have occurred in tropical forests and burned millions of hectares in several countries. The numerous ecosystems of the tropics have differing levels of fire resistance, resilience or dependence. At present, there is little appreciation of the seriousness of the wild fire situation in tropical rainforests but there is even less understanding of the role that fire plays in the ecology of many fire adapted tropical ecosystems, such as savannas, grasslands and other forest types.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Existe una necesidad de realizar estudios de los incendios forestales a nivel regional, puesto que tanto sus efectos como la regeneración de las zonas afectadas dependen de las condiciones climáticas, edáficas, biogeográficas y estacionales de cada zona concreta. Por este motivo se planteó este proyecto cuyo objetivo principal es estudiar los efectos de dos incendios fortuitos en las propiedades físicas, químicas y bioquímicas en el suelo de un pinar. Ambos incendios se produjeron el 18 de Junio de 2004 en los T.M de Aldeamayor de San Martín, Portillo y La Parrilla (Valladolid). En cada incendio se seleccionó una zona quemada y otra testigo que no fue afectada por el fuego de iguales características que la anterior y próxima a ella. Además en cada zona quemada se diferenciaron tres intensidades de quemado en campo (alta, moderada y baja) en función de las cuales se compararon los efectos del fuego en las diferentes propiedades del suelo...[Resumen del autor].

Book excerpt: Se han estudiado dieciocho perfiles de suelos, en un pinar de repoblación de Pinus pinaster, en Arenas de San Pedro (Avila), desarrollados a partir del mismo material original (esquistos y cuarcitas). Trece de ellos sufrieron los efectos de un incendio forestal de superficie, que tuvo una duración de diez horas, realizando la toma de muestras a los diez meses del impacto, período durante el cual no hubo lluvias torrenciales. La evaluación del impacto sobre las propiedades físicas, químicas y mineralógicas, conduce a los siguientes resultados: oscurecimiento en superficie; destrucción de la estructura en los perfiles más afectados: no se observa modificación en la textura; aumento del pH, fundamentalmente en superficie, por el aporte de bases; incremento del carbono por combustión incompleta de la vegetación; aumento de la capacidad total de cambio en ...

Book Synopsis Soil Water Repellency by : C.J. Ritsema
Download or read book Soil Water Repellency written by C.J. Ritsema and published by Elsevier. This book was released on 2012-12-02 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has become clear that soil water repellency is much more wide-spread than formerly thought. Water repellency has been reported in most continents of the world for varying land uses and climatic conditions. Soil water repellency often leads to severe runoff and erosion, rapid leaching of surface-applied agrichemicals, and losses of water and nutrient availability for crops. At present, no optimum management strategies exist for water repellent soils, focusing on minimizing environmental risks while maintaining crop production. The book starts with a historical overview of water repellency research, followed by seven thematic sections covering 26 research chapters. The first section discusses the origin, the second the assessment, and the third the occurrence and hydrological implications of soil water repellency. The fourth section is devoted to the effect of fire on water repellency, section five deals with the physics and modeling of flow and transport in water repellent soils, section six presents amelioration techniques and farming strategies to combat soil water repellency, and section seven concludes the book with an extensive bibliography on soil water repellency.
Book Synopsis Forests for People by : Anne M Larson
Download or read book Forests for People written by Anne M Larson and published by Routledge. This book was released on 2012-09-10 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Who has rights to forests and forest resources? In recent years governments in the South have transferred at least 200 million hectares of forests to communities living in and around them . This book assesses the experience of what appears to be a new international trend that has substantially increased the share of the world's forests under community administration. Based on research in over 30 communities in selected countries in Asia (India, Nepal, Philippines, Laos, Indonesia), Africa (Burkina Faso, Cameroon, Ghana) and Latin America (Bolivia, Brazil, Guatemala, Nicaragua), it examines the process and outcomes of granting new rights, assessing a variety of governance issues in implementation, access to forest products and markets and outcomes for people and forests . Forest tenure reforms have been highly varied, ranging from the titling of indigenous territories to the granting of small land areas for forest regeneration or the right to a share in timber revenues. While in many cases these rights have been significant, new statutory rights do not automatically result in rights in practice, and a variety of institutional weaknesses and policy distortions have limited the impacts of change. Through the comparison of selected cases, the chapters explore the nature of forest reform, the extent and meaning of rights transferred or recognized, and the role of authority and citizens' networks in forest governance. They also assess opportunities and obstacles associated with government regulations and markets for forest products and the effects across the cases on livelihoods, forest condition and equity.

Book Synopsis The Soils of Argentina by : Gerardo Rubio
Download or read book The Soils of Argentina written by Gerardo Rubio and published by Springer. This book was released on 2018-05-30 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive book on Argentinian pedology. It discusses the main soil types of Argentina, their geographical distribution, classification, functions, agricultural use, ecological aspects, and the threats to which they have been subjected during centuries of intensive and extensive management. The description of the soils is accompanied by a complete set of data, pictures and maps, including benchmark profiles and an overview of the country's agricultural production. It also deals with future scenarios of the relationships between soil science and other disciplines and the main challenges that soil science will face in the future. Further, the book explores aspects of the main soil forming factors, such as climate, vegetation, geology and geomorphology, making use of new, unpublished data and elaborations, and presents a history of pedological research in Argentina.
