Indigenous vegetables — plant species consumed in specific locations as part of traditional diets — have the potential to diversify cropping systems, increase farm income, and add a range of vital micronutrients to diets. AVRDC – The World Vegetable Center collects and characterizes indigenous vegetables, analyzes their nutritional content, develops safe production methods, and distributes recipes to promote greater consumption of these valuable plants.
