Originally published in 1989, this book is a unique examination of subsistence farming in the developing world, and its potential for development. The author writes from the conviction that the farming system is limited in its potential for development by the energy value of manpower and that unless the plight of developing world communities is understood and the importance of manpower constraint recognized, inputs of development funds will be wasted. Clarifying the strengths and limitations of the subsistence farming system, the book makes clear the complexities and difficulties encountered in achieving agricultural development in the poorest countries - providing an informed insight into the inevitability of future famine.
