Weeds abound in urban and agricultural environments. Depending on region and site, up to 66% of weed sp edible, and may constitute an additional food source for humans. Based on 400 samples, ¼ m2 each, collect areas (e.g., roadsides, urban vacant lots, streets, sugar cane and coffee plantations in Coatepec, Mexico), av of edible fresh biomass vary between 1277 and 3582 kg/ha. A similar survey performed in a temperate area in Bariloche, Argentina) showed mean values between 287 and 2939 kg/ha. A total of 43 species were samp Coatepec and 32 species in Bariloche. The general means were 2.1 and 1.3 tons/ha, respectively. At a great scale, a comparison between Mexican and Argentine weeds shows that, proportionately, the food parts vary between regions. In general, from higher to lower, the order of uses goes from leaves, seeds, roots, fruits, he and condiments. Edible roots (including bulbs and rhizomes) appear to be more common among perennials t annuals.2 each, collect areas (e.g., roadsides, urban vacant lots, streets, sugar cane and coffee plantations in Coatepec, Mexico), av of edible fresh biomass vary between 1277 and 3582 kg/ha.
