This manual of Roadside Bio-engineering has been developed from an enormous amount of experience, gained throughout the road network of Nepal between 1984 and 1998. It is written for the exceptional conditions found in Nepal (characterised mainly by very active geomorphology, steep slopes, intense rainfall and a restricted economy) and the techniques have been tested under those conditions.
So many people have been involved that it is quite impossible to acknowledge them all. Nothing could have been achieved without the full support of the Department of Roads, the financial support of the Department for International Development of the United Kingdom and the administrative support of Roughton International. In writing this manual I have drawn on material and comments from a large number of people. The main personal contributions and support are listed below.
