Colocasia is a genus of flowering plants in the family Araceae, native to southeastern Asia and the Indian subcontinent. Some species are widely cultivated and naturalized in other tropical and subtropical regions.
Root vegetables are underground plant parts eaten by humans as food. In agricultural and culinary terminology, the term applies to true roots such as taproots and tuberous roots as well as non-roots such as bulbs, corms, rhizomes, and stem tubers.
The Lapita culture is the name given to a Neolithic Austronesian people and their distinct material culture, who settled Island Melanesia via a seaborne migration at around 1600 to 500 BCE. The Lapita people are believed to have originated from the northern Philippines, either directly, via the Mariana Islands, or both. They were notable for their distinctive geometric designs on dentate-stamped pottery, which closely resemble the pottery recovered from the Nagsabaran archaeological site in northern Luzon. The Lapita intermarried with the Papuan populations to various degrees, and are the direct ancestors of the Austronesian peoples of Polynesia, eastern Micronesia, and Island Melanesia.
Dioscorea alata – also called ube, ubi, purple yam, or greater yam, among many other names – is a species of yam. The tubers are usually a vivid violet-purple to bright lavender in color, but some range in color from cream to plain white. It is sometimes confused with taro and the Okinawa sweet potato beniimo (紅芋), however D. alata is also grown in Okinawa. With its origins in the Asian tropics, D. alata has been known to humans since ancient times.
The Neolithic Revolution, also known as the First Agricultural Revolution, was the wide-scale transition of many human cultures during the Neolithic period in Afro-Eurasia from a lifestyle of hunting and gathering to one of agriculture and settlement, making an increasingly large population possible. These settled communities permitted humans to observe and experiment with plants, learning how they grew and developed. This new knowledge led to the domestication of plants into crops.
Taro is a root vegetable. It is the most widely cultivated species of several plants in the family Araceae that are used as vegetables for their corms, leaves, stems and petioles. Taro corms are a food staple in African, Oceanic, East Asian, Southeast Asian and South Asian cultures. Taro is believed to be one of the earliest cultivated plants.
Eddoe or eddo is a species in genus Colocasia, a tropical vegetable, closely related to taro, which is primarily used for its thickened stems (corms). In most cultivars there is an acrid taste that requires careful cooking. The young leaves can also be cooked and eaten, but they have a somewhat acrid taste.
Yam is the common name for some plant species in the genus Dioscorea that form edible tubers.
Dioscorea polystachya or Chinese yam, also called cinnamon-vine, is a species of flowering plant in the yam family. It is sometimes called Chinese potato or by its Korean name ma. It is also called huaishan in Mandarin and wàaih sāan in Cantonese.
Dioscorea bulbifera is a species of true yam in the yam family, Dioscoreaceae. It is native to Africa, Asia and northern Australia. It is widely cultivated and has become naturalized in many regions.
Amorphophallus paeoniifolius, the elephant foot yam or whitespot giant arum, is a tropical plant native to Island Southeast Asia. It is cultivated for its edible tubers in Southeast Asia, South Asia, Madagascar, New Guinea, and the Pacific islands. Because of its production potential and popularity as a vegetable in various cuisines, it can be raised as a cash crop.
Tacca leontopetaloides is a species of flowering plant in the yam family Dioscoreaceae. It is native to the islands of Southeast Asia. Austronesian peoples introduced it as a canoe plant throughout the Indo-Pacific tropics during prehistoric times. It has become naturalized to tropical Africa, South Asia, northern Australia, and Oceania. Common names include Polynesian arrowroot, Fiji arrowroot, East Indies arrowroot, pia, and seashore bat lily.
Perennial vegetables are vegetables that can live for more than two years.
Xanthosoma sagittifolium, or tannia, is a tropical flowering plant from the family Araceae. It produces an edible, starchy corm. X. sagittifolium is native to tropical America where it has been first cultivated. Around the 19th century, the plant spread to Southeast Asia and Africa and has been cultivated there ever since. X. sagittifolium is often confused with the related plant Colocasia esculenta (Taro), which looks very similar and is also used in a similar way. Both plants are often collectively named Cocoyam.
Alocasia macrorrhizos is a species of flowering plant in the arum family (Araceae) that it is native to rainforests of Maritime Southeast Asia, New Guinea, and Queensland and has long been cultivated in South Asia, the Philippines, many Pacific islands, and elsewhere in the tropics. Common names include giant taro, giant alocasia, ʻape, biga, and pia. In Australia it is known as the cunjevoi.
Nigeria is by far the world’s largest producer of yams, accounting for over 70–76 percent of the world production. According to the Food and Agriculture Organization report, in 1985, Nigeria produced 18.3 million tonnes of yam from 1.5 million hectares, representing 73.8 percent of total yam production in Africa. According to 2008 figures, yam production in Nigeria has nearly doubled since 1985, with Nigeria producing 35.017 million metric tonnes with value equivalent of US$5.654 billion. In perspective, the world's second and third largest producers of yams, Côte d'Ivoire and Ghana, only produced 6.9 and 4.8 million tonnes of yams in 2008 respectively. According to the International Institute of Tropical Agriculture, Nigeria accounted for about 70 percent of the world production amounting to 17 million tonnes from land area 2,837,000 hectares under yam cultivation.
Ube halaya or halayang ube is a Philippine dessert made from boiled and mashed purple yam. Ube halaya is the main base in ube/purple yam flavored-pastries and ube ice cream. It can also be incorporated in other desserts such as halo-halo. It is also commonly anglicized as ube jam, or called by its original native name, nilupak na ube.
Dioscorea dumetorum, also known as the bitter yam, cluster yam, trifoliate yam, or three-leaved yam, is a species of flowering plant in the yam family, Dioscorea. It is native to sub-Saharan Africa and especially common in the tropical regions of West Africa, including Nigeria, Benin, and Ghana. D. dumetorum has both toxic and non-toxic varieties.
One of the major human migration events was the maritime settlement of the islands of the Indo-Pacific by the Austronesian peoples, believed to have started from at least 5,500 to 4,000 BP. These migrations were accompanied by a set of domesticated, semi-domesticated, and commensal plants and animals transported via outrigger ships and catamarans that enabled early Austronesians to thrive in the islands of Maritime Southeast Asia, Near Oceania (Melanesia), Remote Oceania, Madagascar, and the Comoros Islands.
