How come its wealthy jamaas who contributed to building Kenya? Could someone have done so and remained kawa/poor? Or was their wealth a byproduct of their kujenga-nchi energies?

The link doesn't say he introduced maize to East Africa


I never knew this much about about Lord Delamere. I think some of this history should be taught in school purposely for character building.

[quote=Wikipedia]Among Kenya's white settlers, Lord Delamere was famous for his utter devotion to developing Kenyan agriculture. For many years his only homes in Kenya were native-style mud and grass huts, which his wife (who was Ulster Anglo-Irish) decorated with their fine British and Irish furnishings. For twenty years, Delamere farmed his colossal land by trial, error and dogged effort, experimenting endlessly with crops and livestock, and accruing an invaluable stockpile of knowledge that would later serve as the foundation for the agricultural economy of the colony.

By 1905, Delamere was a pioneer of the East African dairy industry. He was also a pioneer at crossbreeding animals, beginning with sheep and chicken, then moving to cattle; most of his imported animals, however, succumbed to diseases such as foot and mouth and Red water disease.Delamere purchased Ryeland Rams from England to mate with 11,000 Maasai ewes, and in 1904, imported 500 pure-bred merino ewes from New Zealand. Four-fifths of the merino ewes quickly died, and the remaining stock were moved to Delamere's Soysambu Ranch, as well as the remaining stock of 1,500 imported cattle that suffered from pleuro-pneumonia.

Eventually, Lord Delamere decided to grow wheat. This, too, was plagued by disease, specifically Rust (fungus).[15] By 1909, Delamere was out of money, resting his last hopes on a 1,200-acre (4.9 km2) wheat crop that eventually failed. He was quoted by author Elspeth Huxley as commenting drily, 'I started to grow wheat in East Africa to prove that though I lived on the equator, I was not in an equatorial country.' Delamere eventually created a 'wheat laboratory' on his farm, employing scientists to manufacture hardy wheat varieties for the Kenyan highlands. To supplement his income, he even tried raising ostriches for their feathers, importing incubators from Europe; this venture also failed with the advent of the motor car and the decline in fashion of feathered hats. Delamere was the first European to start a maize farm, Florida Farm, in the Rongai Valley, and established the first flour mill in Kenya.By 1914, his efforts finally began to generate a profit.
