Contact Laura Parsons if you can provide assistance in anyway. Don't know if this really is a 'practical guide'. Purpose of handbook needs to be more clearly defined here. Maybe set up a 'road map' for the rest of the book.
Audience needs to be more clearly state here and through the rest of the book.
Secondary, any engr. who works in the Third World. It could actually be read by anyone wanting to work in developing countries because I think the same philosophies apply across the board. This section is pretty weak. Something more substantial should be added. People have had a difficult time understanding them.
