Pyrethrum and sisal were important colonial-era cash crops that defined regional economies. Both have declined due to global competition, changing markets, and crop shifts.
Pyrethrum
Origins - Pyrethrum (insecticidal flower) was introduced to Kenya's highlands in the early 1900s. Its extraction for natural insecticide made it valuable.
Peak - Pyrethrum was grown widely in Rift Valley highlands (Nakuru, Kericho, Eldoret). By the 1970s, production was substantial.
Decline - Synthetic insecticides (pyrethroids) replaced natural pyrethrum. Demand fell. Production declined from peaks of 10,000+ tonnes to low levels today.
Sisal
Origins - Sisal (agave) was grown primarily on the Coast and in Eastern Kenya for its fibre, used in rope and twine.
Market - Sisal had global demand for shipping rope, agricultural twine, and other uses. By the 1970s, sisal was a significant crop.
Synthetic Competition - Plastic rope and synthetic fibres replaced sisal. Demand collapsed. Sisal production ended in most areas by the 1990s.
Geographic Legacy
Both crops left legacies in their production regions. Rift Valley communities grew dependent on pyrethrum income. Coastal communities integrated sisal into their economy. Crop decline caused economic disruption in these zones.

Attempted Revivals
Organic and fair-trade movements have sparked modest interest in pyrethrum (for organic insecticide). However, volumes remain small relative to historical levels.
Outlook
Both crops are unlikely to return to former significance. However, niche markets (organic pyrethrum, artisanal sisal products) may support small-scale production.
