Why do cocoa farms grow other things as well?
Because a single perennial crop with one price and one harvest calendar is a concentrated risk. Intercropping spreads it, and the crops that do it best are usually the ones that also provide the shade canopy.

Describes what happens on an individual farm or plot. It does not aggregate to a region.
Emerging research
Real human studies exist and point somewhere, but the body of evidence is small, mixed, short-term or heavily industry-funded.
What the evidence shows
Cocoa-growing households typically derive income from several sources. Other crops — plantain, banana, cassava, oil palm, rubber, timber, fruit — food grown for the household, livestock, off-farm labour and remittances all appear in household surveys, and the share of income from cocoa alone is often well under what the phrase 'cocoa farmer' implies.
Diversification serves several functions at once. It smooths income across a year in which cocoa pays in concentrated periods; it provides food that does not have to be bought; it hedges a bad cocoa season; and where the diversifying species are trees, it supplies the shade canopy discussed in the land-use topics.
That last overlap is the important one. A canopy species that produces a marketable crop is agronomically useful, ecologically useful and economically defensible at the same time — which makes it far more likely to still be standing in ten years than a shade tree valued only for shade.
What it does not show
It does not show that diversification raises total income. It generally reduces variance rather than increasing the mean, and where land is scarce it trades cocoa area for other production. Reduced risk is worth having and is not the same as being better off.
It does not show that intercropping is always agronomically neutral. Competition for light, water and nutrients is real, and some combinations reduce cocoa yield more than the intercrop returns.
And it does not show that households are free to diversify. Doing so needs land, labour, planting material, a market for the second crop and the ability to wait — all of which are exactly what constrained households lack.
What the outcome depends on
Every finding above is conditional on these. Change one and the conclusion can reverse.
- Whether a market exists for the second crop within reach of the farm.
- Land and labour availability, since diversification competes for both.
- Species compatibility — shade and root competition can cost more cocoa yield than the intercrop returns.
- Household capacity to wait through establishment of a perennial intercrop.
- Whether the intercrop is food for the household or a cash crop, which are different economic functions.
The misreading to avoid
That a diversified farm is a less committed or less professional cocoa farm. Diversification is a risk-management response to a volatile single-commodity income, and the households that can least afford a bad year have the strongest reason for it.
How good is the evidence
Household income composition is reasonably well documented in the major West African surveys and thinner elsewhere. The agronomic interaction between cocoa and specific intercrops is studied unevenly, with well-covered combinations and many uncovered ones. Effects on income variance are better supported than effects on income level.
Where informed people disagree
Recorded rather than resolved. These are live disagreements between people who have read the same material, and this site has no standing to settle them.
- Whether policy should encourage diversification within cocoa farms or diversification out of cocoa altogether for the smallest holdings.

- Cacao agroforestryRead alongside Income diversification and intercropping. Cacao tolerates shade, so it can be grown under a canopy rather than in open rows. Systems built that way measure better on several environmental outcomes and worse on yield — and how much of each depends on the canopy, the site, and what the land was before.
