Abstract
THE author estimates that about one-half of the area of cultivable land in the world lies within the torrid zone. When one considers the wide range of rainfall, humidity, temperature, peoples and civilisations which exist in the tropics, one realises that the agriculture of this part of the world embraces a very much wider field than can possibly occur in the temperate zones, where the range of such conditions is much more limited.
