Vetiver Grass
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.
Vetiveria
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
Vetiver Grass
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.

Vetiver
Vetiver: Extra Mile presents the tale of an immigrant arriving in the United States, painting a portrait that may be unfamiliar to many. This memoir, written in narrative fashion, tells the story of M, a young medical student who immigrates to the country. While exploring MÕs relationship with his new home and with his family, it describes the changes in health care in the United States over the last twenty yearsÑthough it does not seek to resolve the question of whether these changes are good or bad. It also considers various aspects of American medicine in general and American medical training in particular. WhatÕs more, MÕs recollections depict some of the trials and successes that immigrants face when beginning life in a new country. Through direct and personal storytelling, Vetiver: Extra Mile offers a firsthand perspective of immigrations and medicine from one uniquely suited to provide it.
Ecological Building Materials for Deserts and Drylands
This book examines prospective climate adaptive building materials in desert and drylands in the context of climate change, desertification, urbanisation demands, and the consequent sustainable urban development challenges. This preliminary collection of ecological materials covers the characterisation of biotic and abiotic resources for materials, their specifications and benefits for adequate bio-climatic design and construction. Particular emphasis is given to ecological composite materials for advances in desert architecture. Based on the initial collection, the book culminates with potentials for new ecological building materials. The "eComposite Combinator" matrix offers potential research recipes and encourages the reader to conduct further climate-matters related research.
