This book had its genesis in Alexandria, Egypt in March 2002 at the Bibliotheca Alexandrina, when the new library hosted a conference on Biotechnology and Sustainable Development: Voices of the South and North. Here, a group of modern scholars met to review the state of the art in relation to the applications of biosciences in human health, food and agriculture and the environment, and address the ethical, institutional, regulatory and socio-economic issues that affect their use. The goal was to identify ways and means by which the new life sciences could be mobilized in the service of humanity and especially to improve the livelihoods of poor people.
