Vetiver Grass Technology Data Base

Compiled by Mike Pease (1998)

To be updated in January 2000

 

 

 

A data base is now available. It is accompanied by a list of the categories (13) and sub-categories under which items are listed.

The data base currently consists of just over 1,100 items extracted from the following publications:

  • World Bank Technical Paper No 273 - Vetiver Grass for Soil and Water Conservation, Land Rehabilitation, and Embankment Stabilization. This incorporates all earlier Newsletters and the Vetiver Handbook. Itemised in the D. Base as "W.B. Tech 273"
  • Newsletters at Vetiver Network FTP site
  • "Vetiver Grass-A thin Green Line against Erosion" produced by the Board on Science and Technology for International Development, National Research Council, USA. Itemised in the D. Base as, "BOSTID".
  • United States Department of Agriculture Workshop on Grass Hedges for Erosion Control, 1996--Executive Summary. Itemised in the D. Base as "USDA W'sp 96".

The data base will be maintained on a regular basis with extracts from publications, such as Newsletters, as they become available.

This first attempt at producing a data base will need improvement over time. For instance, it may be necessary to improve upon main and sub-categorization; unnecessary duplications may have been included; abbreviations may not be clear. Members are invited to submit suggestions for the improvement of the data base, other than its complete revision, direct to: Michael Pease, Quinta das Espargosas, Odiaxere, 8600 Lagos, Algarve, Portugal.
