Sweet Potatoes and Yams

The truth is what you call a yam is most likely a sweet potato. Yams and sweet potatoes are both flowering plants however, that is their only relation. Compared to sweet potatoes, yams are starchier and drier.

What is the Difference Between Sweet Potatoes and Yams



The mix-up between yams and sweet potatoes began in the United States when firm varieties of sweet potatoes were grown by African slaves before soft varieties. They called the soft sweet potatoes yams because they resembled the yams in Africa. Therefore, soft sweet potatoes were referred to as yams to distinguish them from the new firm varieties.

Sweet potato varieties are classified as either firm or soft. The skin color can range from white to yellow, red, purple or brown. The flesh also ranges in color from white to yellow, orange, or orange-red. Currently, sweet potatoes are the 3rd most important crop in seven eastern and central African countries, and fourth in six southern African countries.

Yams are native to Africa and Asia. The sweet potato, maybe native to tropical America introduced to Western Africa by the Portuguese in the 1500s. The sweet potato is its 3rd most important agricultural product in terms of volume after the plantain and the cassava. Uganda leads the way in the production of sweet potatoes representing half the African supply followed by Nigeria and Tanzania.

The yam belt of West Africa includes Nigeria, Ghana, Benin, Côte d'Ivoire, Central Africa, Cameroon and Togo, Nigeria alone produces 71 percent of the yams. Yams are second to cassava as the most important tropical root crop and are a staple food in many parts of Africa, Southeast Asia, and the South Pacific. Seventy percent of the 50 million tons world output of 2008 was grown in Nigeria.

The starchy tuber, with rough brown skin, is produced by an annual vine and takes from 8 to 11 months to mature after planting. Yams are mainly grown for cooking and eating. The tubers can be stored for up to six months without refrigeration. Yams are second to cassava as the most important tropical root crop.

Yams are one of the most common and popular root crops in tropical and semi-tropical regions of Africa and have become a mainstay of many African cultures. Besides their importance as a food source, yams also play a significant role in the social and cultural lives of Africans. The celebrated New Yam Festival in West Africa is an anticipated event each year and a practice that has extended to overseas where there is a significant population of Igbo tribes. Considered a prestigious crop, it is the crop of choice for traditional feasts, gifts and fulfilling social obligations to many Nigerian Igbo Africans.

Yams store relatively longer in comparison with other tropical fresh produce and therefore stored yam represents stored wealth which can be sold all-year-round by the farmer or marketer. In parts of Igboland in Southeastern Nigeria, it is customary for the parents of a bride to offer her yams for planting as a resource to assist them in raising a family. Most of the world production of yam is from Africa about 96% with Nigeria alone accounting for nearly 75% of the total world production.

Nature Holds Many Secrets | Hurricanes, Angry African Ancestors

Eastern coasts of Caribbean, United States, and South America, are in danger of being blasted by hurricanes wind and rain during hurricane season from June through November. But, why?  

The scientific reason why is because of Africa’s Sahara desert dust storms and the transition of thunderstorms off the west coast of Africa. The waters in the North Atlantic Ocean are typically at their warmest while the Sahara is at its hottest from July through October, so the chances of a hurricane are highest during these months.
Hurricanes are gigantic weather systems using convection, the movement of hot and cold air, to create dangerous storms. They are rotating heat engines powered by the warmth of tropical waters having three main parts, the eye, the eyewall, and rainbands. 

Hurricanes cannot form just anywhere in the world due to the need for hot and humid air. They normally form close to the equator and move west or northwest. Hurricane Alley is a stretch of warm water through the Atlantic Ocea…

Charging Cell Phones in Rural Africa

The simple task of charging a cell phone is no simple matter in rural African villages far from an electric grid.
With the advent of tiny rooftop solar panels electricity could be accessible to millions.
African governments are struggling to meet to electric needs of the poorest of the poor living in rural areas. 

Living off-grid may be a lifestyle choice to some and a fact of everyday living to the poorest of the poor. However, tiny rooftop solar panels and high-efficiency LED lights across the African continent could provide enough electricity to charge cell phones. 

Cell phones are vital for people in rural areas with no access to banks in order to send and receive money, access medical care and stay in contact with family and friends.
What does Off-Grid Mean? Off the grid (off-grid) means creating your own self-sufficient environment and being able to operate completely independently of all trad…

Survival of the Fattest Meaning
The copper statue Survival of the Fattest by Jens Galschiøt and Lars Calmar was created in 2002. The fat woman is holding a pair of scales as a symbol of justice however; she is closing her eyes so the justice. Galschiot symbolized the woman as being blind, refusing to see the obvious injustice.
