Over the past decade the importance of natural resources for sustainable agricultural development has been increasingly discussed at international forums and conferences. Aside from the sustainable management of soil, water, and air, it now seems to be accepted that the sustainable management of genetic resources is one of the four indispensable preconditions for a sustainable agriculture. The discussion on conservation of plant genetic resources for food and agriculture (PGRFA), however, has to reflect the costs of conservation as well. These have not yet been discussed intensively. The...

The book reflects the work in progress regarding the analysis of the costs of crop genetic resources conservation that has been conducted at various research insti- tutes over the last couple of years, including research conducted at ZEF and asso- ciated institutes. In addition, contributions in this publication were presented at a special session during the "Global Dialogue: The Role of the Village in the 2]'1 Century: Crops, Jobs and Livelihood" in Hannover, Germany, at the World Exposition in Au- gust 2000. The purpose of the publication is to make a general contribution to the ongoing...

Electromagnetic waves and their role in probing the earth are important for the exploration of the earth's deep crust. This book is not only for scientists in geophysics a useful source of information, but also for professionals in oil and gas exploration, geophysicists and engineers alike.

The contributions in this publication are grouped around four major themes: political and institutional frameworks to foster rural development; natural resources management; broadening the technological base of rural economies; and improved linkages between urban and rural areas.
