A major challenge of the 21st Century will be to ensure sufficient global food production to cope with the ever-increasing world population. Soils, Land and Food is a short text aimed at undergraduates, graduates, agricultural scientists and policy makers which describes how the use of technology in soil management can increase and sustain food production. Particular emphasis is placed on the need for both economic change and technological intervention in developing countries where, in many cases, food production will need to more than double in the next fifty years.
