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.

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.

Book Description
Vetiveria is one of the most versatile genera in plant kingdom. For example, the species Vetiveria zizanoides produces oderous roots from which a precious essential oil is distilled and used in a variety of applications from perfumery to ethnopharmacology. The same roots give the plant particular characteristics that make it a valuable natural barr

Book Description
Phytoremediation Potential of Perennial Grasses provides readers with the knowledge to select specific perennial grass species according to site-specific needs. In addition, it demonstrates the potential opportunities for grass-based phytoremediation to yield phytoproducts, especially biomass-based bioenergy and aromatic essential oils as a green economy while in the process of remediating contaminated sites. The book brings together recent and established knowledge on different aspects of grass-based phytoremediation, providing this information in a single source that offers a cutting-edge synthesis of scientific and experiential knowledge on polluted site restoration that is useful for both practitioners and scientists in environmental science and ecology. - Provides a holistic approach to grass-based phytoremediation, covering the ecological, economic and social issues related to its management - Addresses the key role that grass-based phytoremediation plays in maintaining ecosystem services in polluted sites - Includes strategies to mitigate costs related to the phytoremediation of polluted sites

Book Description
This book is a timely contribution towards the debate on the most effective way to bring about sustainable farming in marginal areas. It offers a detailed analysis of the social, economic, and agro-ecological characteristic of both Soil and Water Conservation (SWC) and Better Land Husbandry (BLH) and an analysis of case studies of BLH from Central and South America, Africa, and Asia.
