Edible and Tended Wild Plants, Traditional Ecological Knowledge and Agroecology

Abstract

Humans the world over have depended on wild-growing plants in their diets for hundreds of thousands of years, and many people continue to rely on these species to meet at least part of their daily nutritional needs. Wild harvested plant foods include: roots and other underground parts; shoots and leafy greens; berries and other fleshy fruits; grains, nuts and seeds; and mushrooms, lichens, algae and other species. Use of any of these species requires special cultural knowledge regarding harvesting, preparation, cooking and other forms of processing. Many were, and are, prepared and served in mixtures or combinations. In most cases, too, the species are managed, tended or manipulated in some way to increase their productivity and availability. Many of the most widely used species are categorized as weeds—species that grow and reproduce readily in disturbed or cleared land, and are common around human settlements and agricultural areas. This paper presents case examples of edible wild plant use and the roles of these species in agroecosystems from different parts of the world and discusses similarities and differences in use across different cultures and segments of society.
