Cassava: One Root, a Thousand Products — Africa's Most Underused Industrial Crop

Cassava is Africa's largest food crop by volume and its most under-monetised trade asset. The continent grows roughly two-thirds of the world's cassava roots, yet it barely registers in the global trade of cassava-derived products — starch, flour, sweeteners, ethanol — that now support a multi-billion-dollar processing economy dominated almost entirely by Thailand, Vietnam, and China. This is the gum arabic story, the cashew story, and the shea story again: raw abundance at origin, industrial value capture downstream. It is also, increasingly, a story with a way out — through High-Quality Cassava Flour (HQCF), wheat-blending policy, and the global gluten-free wave.

## What cassava actually becomes

Cassava's versatility is the point. A single root feeds households, industries, and now health-food shelves in the West:

- **Food staples** — garri, fufu, lafun, attiéké, chikwangue, eba, and dozens of regional swallow and fermented products that form the daily caloric base for hundreds of millions across West and Central Africa.

- **High-Quality Cassava Flour (HQCF)** — unfermented, white, odourless flour used as a wheat substitute in bread, biscuits, and pasta.

- **Native and modified starch** — used in food (thickeners, sweeteners, MSG production), paper, textiles, adhesives, cosmetics, and pharmaceuticals.

- **Cassava chips and pellets** — dried, exported in bulk mainly for animal feed and industrial alcohol/ethanol production.

- **Bioethanol** — a growing feedstock for biofuel blending programmes, especially in Asia.

- **Industrial glucose syrup** — a sugar-substitute input for confectionery and beverages.

## Nutritional profile

Cassava is calorie-dense and naturally gluten-free, which is precisely why the Western "alternative flour" market has fallen for it:

- A quarter-cup serving of cassava flour carries under 120 calories — lower than almond or coconut flour equivalents.

- It is rich in resistant starch and dietary fibre, which support digestive and metabolic health, and carries a comparatively low glycaemic index versus refined wheat flour.

- It has a near 1:1 substitution ratio with wheat flour in baking — unlike most gluten-free flours, which need gums and blends to behave properly in dough — making it functionally, not just nutritionally, attractive to food manufacturers.

- Raw and improperly processed cassava contains cyanogenic compounds; proper peeling, soaking, fermentation, and drying (as in HQCF and garri production) neutralise this, which is why processing standards — not just yields — determine market access.

## Who actually grows it

In 2023, Nigeria was the largest producer of cassava, followed by Democratic Republic of the Congo, Thailand, Ghana, Brazil, Indonesia, Cambodia, Angola, Vietnam, Mozambique, with Nigeria holding the largest share of cassava production quantity at 18.79%, its production reaching 62.69 million tonnes in 2023. In 2024, global cassava root production exceeded 313 million metric tons, with Africa contributing nearly 63%, followed by Asia at 33% and Latin America at 4%.

**Top production, in order:** Nigeria, DR Congo, Thailand, Ghana, Brazil, Indonesia, Cambodia, Angola, Vietnam, Mozambique — a list Africa dominates by count of countries even as Asia dominates by trade value.

The catch: Africa is the world's largest cassava-producing region, but it has relatively low cassava exports, largely because cassava is a staple food critical for local food security and because limited storage and processing technologies restrict large-scale exports. In Nigeria specifically, approximately 90% of fresh cassava roots are consumed locally.

## Who actually processes it — and captures the margin

This is where the sovereign value gap opens wide. Despite Africa's dominance in raw cassava production, the majority of export-oriented tapioca starch processing capacity is located in Asia-Pacific, particularly Thailand, Vietnam, Indonesia, and China. Asia-Pacific accounts for approximately 72% of global native tapioca starch production output, built on over 600 processing units clustered near cassava-growing zones to minimise post-harvest losses — infrastructure Africa has never built at comparable scale.

Thailand remains the anchor processor and exporter. In 2024, Thailand was projected to remain the world's largest exporter of cassava products, securing 25% of total global export volume, with cassava chips accounting for 19% of its export portfolio, native tapioca starch for 62%, and modified tapioca starch for 31%. Vietnam has climbed fast behind it: Vietnam exports approximately 2–3 million metric tons of cassava-related products annually, with the tapioca starch sector alone reaching USD 1.03 billion in export value in 2023. Laos is now the disruptive third force — Lao exports to China rose from under USD 15 million in 2020 to almost USD 200 million in 2024, powered by nearly 30 new Chinese-backed starch processing facilities and about 400,000 farmers, using the China-Laos Railway to bypass Thai and Vietnamese middlemen entirely.

## Who is buying

China is, overwhelmingly, the buyer of last-mile cassava value:

- China absorbs approximately 46% of total global tapioca starch import shipments by volume, meaning Chinese purchasing behaviour single-handedly sets the world price.

- China imported 543,200 tonnes of tapioca starch in March 2026 alone, and earlier trade data shows the scale of this appetite: from January to July of a recent year, China imported 2.05 million tons of cassava starch worth $1.08 billion, sourced mainly from Thailand and Vietnam.

- By early 2025, Vietnam alone supplied China with over 1.14 million tons of cassava starch — nearly 49% of China's total cassava starch imports — followed by Thailand (806,000 tons) and Laos (352,000 tons).

- Beyond China, Western demand is a fast-rising second buyer category — but for finished cassava flour, not raw starch, driven entirely by the gluten-free and clean-label consumer trend (see below).

**Africa is nearly invisible in this buyer-side picture.** The continent that grows the crop is not among the countries that sell the starch.

## The alternative-flour opportunity — and where the real number sits

Cassava/HQCF flour market-sizing reports vary wildly — some conflate cassava flour with the far larger cassava starch and derivatives complex, producing headline figures anywhere from roughly half a billion to over fifty billion dollars for the "same" 2025 market. Treat any single big number with caution. What the underlying demand data agrees on is the *direction*: gluten-free, paleo, and clean-label demand in North America and Europe is real and growing, cassava flour's 1:1 wheat-substitution property gives it a structural edge over almond, coconut, and sorghum alternatives, and food manufacturers in North America and Europe have increased their use of cassava flour by 38% since 2020 in response to consumer demand for clean-label, allergen-free ingredients.

The sharper, more Africa-relevant opportunity is domestic import substitution, and Nigeria is the live case study:

- Nigeria has the world's largest cassava output, yet less than two percent of its harvest is transformed into High-Quality Cassava Flour — a staggering under-conversion rate for the world's number-one producer.

- Current industry estimates suggest actual HQCF inclusion in composite flour today is around 1%, worth up to US $35 million — but if Nigeria hits the 20% substitution target proposed in its Cassava Flour Mandatory Inclusion Bill, market potential could scale to US $1.18 billion by 2030.

- Vice-President Kashim Shettima described cassava as "one of the most strategic assets in our agricultural portfolio," citing applications in food, feed, fuel, pharmaceuticals, textiles, and construction, as Nigeria positioned itself around a $7 billion cassava opportunity at the July 2025 World Cassava Day event.

- The obstacle is not demand, it's competitiveness: HQCF has recently priced around 9% more expensive than wheat flour, largely due to inefficient feedstock sourcing, underdeveloped logistics, and weak coordination across actors, and the bread segment alone represents a potential market of about 351,000 tons and US $236 million in revenue if the supply-side gap is closed.

This is a textbook case of policy intent outrunning processing infrastructure — exactly the kind of gap RACS-style cold chain and processing investment exists to close.

## Inter-Africa opportunity

The inter-Africa case is arguably stronger than the export case, and less contested:

- Nigeria, DRC, Ghana, Angola, and Mozambique together represent enormous adjacent production bases with almost no formal cross-border processed-cassava trade between them.

- A pan-African HQCF and starch trade — Nigeria and Ghana supplying flour into food-import-dependent West African neighbours, or DRC and Angola anchoring Central African processing hubs — would displace wheat and starch imports currently paid for in hard currency, while keeping value inside AfCFTA borders.

- Nigeria's own 80/20 wheat-blending mandate, if it works, is a template exportable to Ghana, Côte d'Ivoire, and other cassava-heavy, wheat-import-dependent economies — each with the same foreign exchange pressure Nigeria is trying to solve.

## Global opportunity

- **Feed and industrial chips/pellets to Asia** — the China-driven chip and pellet trade is enormous but structurally risky: China cut its imports of cassava chip in 2023–2024 and switched to corn instead, causing a significant drop in Thai chip exports to 2.0 million tons, showing how exposed even the dominant Asian exporters are to a single buyer's substitution decisions. Africa entering this trade late would inherit the same fragility unless it diversifies buyers from day one.

- **Starch and flour to the West** — smaller in volume than the Asia-China corridor, but higher-margin, less commoditised, and aligned with the clean-label premium consumers are already paying for.

- **Landed-cost arbitrage** — the gap between Thai FOB pricing (roughly USD 435–580/MT in 2026) and European or North American landed cost (USD 900–1,450/MT) reflects freight, duty, packaging, and distribution margin that an Africa-to-Europe or Africa-to-Gulf direct corridor could compress and capture, rather than ceding it to Southeast Asian re-exporters.

## What's missing

1. **Drying and processing infrastructure at the farmgate.** Cassava roots spoil within 24–48 hours of harvest; this is the single biggest reason Africa's raw abundance never converts into exportable product. Thailand and Vietnam solved this with dense networks of processing units built directly into growing zones — Africa has not.

2. **Quality and granulation standardisation.** Nigerian processors "struggle to meet industrial standards for granulation, moisture content, and shelf life" — the exact specifications international and even domestic industrial buyers require before they'll commit to volume contracts.

3. **Cost-competitive HQCF pricing.** A 9% price premium over wheat flour, driven by fragmented sourcing and weak logistics coordination, is small on paper but decisive in a price-sensitive baking industry.

4. **Buyer diversification.** Africa has almost no direct trade relationships with the Chinese, European, or North American buyers who already move billions of dollars in cassava-derived product every year — the entire trade currently routes through Southeast Asian intermediaries.

5. **Enforcement, not just legislation, of blending mandates.** Nigeria's bill has existed in various forms for years; the market-scaling only happens once inclusion mandates are actually enforced across the milling and baking industry, not merely proposed.

6. **Regional (AfCFTA) processing corridors.** No pan-African cassava trade infrastructure yet exists to let Nigeria, Ghana, DRC, and Angola trade processed cassava products with each other at scale — the crop is grown everywhere and processed nowhere collectively.

## The sovereign lens

Cassava is Africa's clearest food-sovereignty and knowledge-transfer opportunity in one crop: it is indigenous to the continent's food systems, it displaces costly wheat and starch imports, and its industrial derivatives — flour, starch, ethanol, glucose — sit in markets Africa currently only supplies as unprocessed root. The Thailand-Vietnam-Laos trade corridor into China proves the model works; it simply hasn't been built on African soil yet. Closing that gap is not a subsistence-crop story anymore — it's an industrial one.
