Vetiver Grass
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309042690
Category : Technology & Engineering
Languages : en
Pages : 186
Book Description
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.

Restoration of Aquatic Ecosystems
Author: National Research Council
Publisher: National Academies Press
ISBN: 9780309045346
Category : Technology & Engineering
Languages : en
Pages : 580
Book Description
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Vetiver Grass
Author: John C. Greenfield
Publisher: World Bank Publications
ISBN: 9780821314050
Category : Business & Economics
Languages : en
Pages : 86
Book Description
This handbook has been prepared to support fieldworkers and farmers in developing vegetative systems of soil and mositure conservation that will meet the requirements of small farmers in developing countries, most of whom reside in the tropics and semitropics. Experience has shown that conventional systems of earth bunds or terraces on small farms are expensive and in many cases, especially in modern times, ineffective. When applied correctly, vegetative systems of soil and mositure conservation - particulary the system of hedges of vetiver grass described in this handbook - have proved cheaper and more effective.
