Since the "Green Revolution", world food production has grown at a dizzy pace. Yet hunger continues to spread throughout the globe, chiefly in the countryside, as small farmers are increasingly forced into ruin. The agro-industrial model is thus showing signs of fatigue.

More and more peasant farmers are seeing ecological agriculture, combining ancestral and new methods, as a sustainable solution. This brings about new challenges, such as how to recover knowledge that was becoming lost, adapt it to current conditions and complement it with new knowledge. The creation of mechanisms to generate and share knowledge - both among farmers and with investigators and specialist centres -, is now a condition of survival of rural communities.

This book explores these issues, combining reflections with concrete experiences that, among other things, are experimenting how new information and communications technologies can foster effective knowledge sharing.
