The atoll countries of the Pacific Ocean, such as Kiribati, Tuvalu and Marshall Islands, are home to probably the most economically and environmentally vulnerable people on this earth. They currently face significant nutrition insecurity and their greatest challenge is to produce enough good-quality food for their people.
Producing food crops on atoll islands requires perseverance. The porous and alkaline soils have limited fertility and support only a narrow range of crops. Increasing soil fertility to support production of more good-quality food and reduce nutrition insecurity is a common challenge for Pacific atoll countries, with the main constraint being lack of appropriate technology.
Development and use of technologies to increase food crop production will improve both local food security and nutritional security for atoll populations. This manual provides guidelines for growing four root crops in atoll conditions: sweet potato, taro, cassava and yam.
