Download or read book Vetiver Grass written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: For developing nations, soil erosion is among the most chronic environmental and economic burdens. Vast amounts of topsoil are washed or blown away from arable land only to accumulate in rivers, reservoirs, harbors, and estuaries, thereby creating a double disaster: a vital resource disappears from where it is desperately needed and is deposited where it is equally unwanted. Despite much rhetoric and effort, little has been done to overcome this problem. Vetiver, a little-known tropical grass, offers one practical and inexpensive way to control erosion on a huge scale in both humid and semi-arid regions. Hedges of this deeply rooted species catch and hold back sediments while the stiff foliage acts as a filter that also slows runoff and keeps moisture on site. This book assesses vetiver's promise and limitations and identifies places where this grass can be deployed without undue environmental risk.

Download or read book Forest Hydrology written by Mingteh Chang and published by CRC Press. This book was released on 2006-05-25 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although a few texts on forest hydrology are available, they cover very little, if any, background on water resources. On the other hand, books dealing with water resources do not cover topics on forest-water relations. The one exception to this is Forest Hydrology: An Introduction to Water and Forests. Now with the publication of a revised edition, this volume adds information from recent studies to go even further in providing an introduction to forest hydrology that brings water resources and forest-water relations into a single practical and comprehensive volume Focusing on processes and general principles, the first six chapters provide an introduction and basic background in water and water resources, while the last seven chapters look at the impact of forests on water. Between these two groupings is a chapter that serves as an entry to the study of forest impacts on water resources, describing forests and forest characteristics important to water circulation, sediment movement, and stream habitat. This second edition also features new information on forests and flooding, forest and stream habitat, snow vaporization processes, and GIS methods in hydrology research, examples on evaporation estimates, and a new appendix on forest interception measurements. Employing examples and case studies, the book provides tools to help natural resource managers play an active role in policymaking and land-use planning, and in developing partnerships with stakeholders. It also offers unique perspectives for addressing urban sprawl.

Download or read book Exotic Brome Grasses in Arid and Semiarid Ecosystems of the Western US written by Matthew J. Germino and published by Springer. This book was released on 2016-01-22 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasions by exotic grasses, particularly annuals, rank among the most extensive and intensive ways that humans are contributing to the transformation of the earth’s surface. The problem is particularly notable with a suite of exotic grasses in the Bromus genus in the arid and semiarid regions that dominate the western United States, which extend from the dry basins near the Sierra and Cascade Ranges across the Intermountain Region and Rockies to about 105° longitude. This genus includes approximately 150 species that have a wide range of invasive and non-invasive tendencies in their home ranges and in North America. Bromus species that became invasive upon introduction to North America in the late 1800’s, such as Bromus tectorum and B. rubens, have since became the dominant cover on millions of hectares. Here, millenia of ecosystem development led to landscapes that would otherwise be dominated by perennial shrubs, herbs, and biotic soil crusts that were able to persist in spite of variable and scarce precipitation. This native ecosystem resilience is increasingly coveted by land owners and managers as more hectares lose their resistance to Bromus grasses and similar exotics and as climate, land use, and disturbance-regime changes are also superimposed. Managers are increasingly challenged to glean basic services from these ecosystems as they become invaded. Exotic annual grasses reduce wildlife and livestock carrying capacity and increase the frequency and extent of wildfi res and associated soil erosion. This book uses a unique ecoregional and multidisciplinary approach to evaluate the invasiveness, impacts, and management of the large Bromus genus. Students, researchers, and practitioners interested in Bromus specifically and invasive exotics in general will benefit from the depth of knowledge summarized in the book.

Download or read book Principles of Soil Conservation and Management written by Humberto Blanco-Canqui and published by Springer Science & Business Media. This book was released on 2008-09-16 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Principles of Soil Management and Conservation” comprehensively reviews the state-of-knowledge on soil erosion and management. It discusses in detail soil conservation topics in relation to soil productivity, environment quality, and agronomic production. It addresses the implications of soil erosion with emphasis on global hotspots and synthesizes available from developed and developing countries. It also critically reviews information on no-till management, organic farming, crop residue management for industrial uses, conservation buffers (e.g., grass buffers, agroforestry systems), and the problem of hypoxia in the Gulf of Mexico and in other regions. This book uniquely addresses the global issues including carbon sequestration, net emissions of CO2, and erosion as a sink or source of C under different scenarios of soil management. It also deliberates the implications of the projected global warming on soil erosion and vice versa. The concern about global food security in relation to soil erosion and strategies for confronting the remaining problems in soil management and conservation are specifically addressed. This volume is suitable for both undergraduate and graduate students interested in understanding the principles of soil conservation and management. The book is also useful for practitioners, extension agents, soil conservationists, and policymakers as an important reference material.

This book was released on 1993-02-28 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on more than 1000 references to English and French articles produced in the region over many decades. A comprehensive review of the achievements in farming and research in both wet and dryland is given, related to the grasslands of: Eastern Africa, extending from Malawi to Eritrea, including Ethiopia, Kenya, Uganda, Tanzania, Somalia, Zambia, Rwanda, Burundi, Sudan and eastern Zaire. Sown grasses, within the time-proven system of mixed-farming based on crop-grass rotations. Fodders, e.g. Elephant grass, dryland-Sorghum, lucerne, Leucaena, tropical legumes and hay.£/LIST£ The main objectives of the book are to illustrate the value of East African grasses and fodders for: Livestock: East Africa is the gene-centre of the world's most famous cultivated tropical grasses capable of achieving high animal performance, also without fertilizer. Soil fertility maintenance: local farmers pioneered the practice of grass fallows with Elephant grass to restore soil fertility. This was later extended to sown grasses to accelerate the restoration process. Crop yields are doubled following pasture. Environmental protection: priority in natural grassland is to prevent deterioration. In crop-pasture rotations grasses are effective in trapping rainfall and in reducing erosion by improved soil structure. Topics discussed include animal manure versus fertilizer; zero versus direct grazing; fodder crops (annual and perennial) versus grass conservation; seed production and plant breeding. The main species in cultivation are described in detail.
