This book takes a multidisciplinary and multicultural approach to studying the relationship between human societies and food- yielding tropical palms. A joint effort of four people whose special ties complement each other, it provides a broad and thorough examination of palm sago, a starch that has potential for small-scale, low-cost development in marginal areas of the tropics. Information on the extraction and production of palm sago in insular and mainland Southeast Asia, the tropical Americas, Melanesia, South China, and South Asia is presented here.
