coffee and cocoa growing The Promise of Polyculture for Cocoa Farmers

Whenever I visit São Tomé and Príncipe, I always call in to see my friend Claudio Corallo — a pioneer of tree-to-bar chocolate. One thing that struck me on my first visit was that he grows not just fine cocoa, but coffee too — on the same land. It got me thinking: why don’t we see more of this in West Africa? Could it work in Ghana’s cocoa farms?

As a chocolatier, cocoa educator, and someone who works closely with cocoa farmers and cooperatives, I’m always exploring ways to help cocoa farms thrive — both environmentally and economically. One idea that keeps popping up is intercropping cocoa with coffee — a form of polyculture farming.

But is this just another farming fad, or could it truly benefit Ghanaian cocoa farmers

The short answer is: yes — it can and does, but it has to be  done with care. In fact, coffee and cocoa can complement each other surprisingly well.

Why Cocoa and Coffee Are Good Neighbours in Agroforestry

Cocoa and coffee are natural allies in the forest. Both evolved under the tropical rainforest canopy and share similar growing requirements:

Filtered sunlight — especially when young

Warm, humid climate — 21–30°C
Well-drained, fertile soils rich in organic matter
Annual rainfall — 1,200–2,000 mm

In Ghana’s cocoa belt — spanning Western, Ashanti, Brong-Ahafo, Eastern, and parts of the Volta Region — these conditions are ideal for both crops.

The Benefits of Growing Coffee with Cocoa
Diversified Income: Relying on cocoa alone can be risky — weather, pests, diseases, or volatile cocoa market prices can hit hard. Intercropping with coffee offers a second income stream, often filling the gaps between cocoa payments.

 Labour Spread Across the Yearcoffee and cocoa growing together

Cocoa harvest: major season Oct–Jan, minor May–Aug Coffee harvest: often ripens Aug–Dec

This spreads out labour demands and provides steadier income for farming families.

Improved Farm Resilience & Biodiversity

Polyculture increases biodiversity, improving natural pest control and soil health.

Coffee bushes act as understorey plants, creating a better microclimate for cocoa.

Different root depths reduce competition and promote healthier soils.

Climate Change Adaptation

As some cocoa zones get warmer or drier, coffee may prove more resilient — particularly in higher elevations or as shade crops.

Potential for Premium Products & Agro-Tourism

Imagine: Ghana-grown chocolate paired with Ghana-grown coffee — both from the same farm. This “bean-to-bar and bean-to-cup” story offers fantastic opportunities for chocolate tourism and export markets.

What to Watch Out For

Of course, it’s no silver bullet. Farmers must manage carefully:

Shade Management

Too much shade = higher fungal risk for cocoa

Too little shade = coffee struggles

Use suitable shade trees such as gliricidia, plantain, albizia, or cola, which can also provide extra income.

Spacing & Competition

Coffee bushes need space — at least 2 x 2 m spacing

Avoid overcrowding, which stresses cocoa roots.

Many farmers plant coffee between cocoa rows, or start new plots on farm edges.

Pests & Diseases

Cocoa: black pod disease, capsid bugs

Coffee: coffee berry borer, leaf rust

Mixed farms help balance pest pressure but require active monitoring.

Market Access

Coffee markets in Ghana are smaller than cocoa.

However, specialty coffee demand is rising — both domestically and for export.

Selling quality coffee requires good processing — careful drying, sorting, and storage.

Real Examples from Ghana & West Africa

Ghana

COCOBOD and NGOs (e.g. SNV, Rainforest Alliance) are piloting cocoa–coffee intercropping in Brong-Ahafoand Ashanti.

Farmers around Nkawkaw and parts of the Eastern Region are reviving old coffee plots alongside cocoa.

Urban demand for Ghana-grown coffee is growing fast.

Cameroon

Many cocoa farmers in Cameroon’s Centre Region intercrop with robusta coffee.

NGO projects show improved income stability and farm resilience with both crops. 

Uganda

Cocoa–coffee farms in Western Uganda (Bundibugyo) demonstrate improved soil fertility and climate resiliencethrough polyculture.

Tips for Farmers Considering Cocoa + Coffee

Start small — try 0.25 to 0.5 ha plots first.
Use known coffee varieties suited to your area — often robusta in Ghana.
Manage shade actively — not too dense, not too open.
Learn about coffee processing — drying is key!
Connect with local buyers — some specialty coffee exporters now operate in Ghana.

A Future-Friendly Farming Model

I see coffee + cocoa intercropping as an ideal model for Ghana’s future cocoa farms:

Better biodiversity

 More stable income

Enhanced climate resilience

New market opportunities: bean-to-bar and bean-to-cup, agro-tourism, carbon credits

Carbon credit projects are already being piloted in West Africa, rewarding farmers for managing polyculture agroforestry systems that boost carbon sequestration.

Cocoa and coffee aren’t just tasty companions — they can be farming companions too. Agroforestry and polyculturehold the key to sustainable, farmer-friendly cocoa systems in Ghana.

And who knows — in a few years, we might see bean-to-bar and bean-to-cup tours across Ghana, offering visitors a taste of both of these beautiful crops.
