Bøker av Peter Stern

This excellent, clearly illustrated book has been written for those working with farmers on development and extension in rural areas who do not have much access to the technical know-how needed for developing irrigated agriculture on a small scale.

For all those involved in simple engineering work in rural areas. Deals with site surveying, engineering materials, water supplies, sanitation in general, planning and construction of roads, simple river crossings, bridges and small dams.
