Value Chain Analysis · Cashew · Ghana Agribusiness Playbook

The Value Chain · Pillar 06

This is the heart of the playbook, which is why it is the longest pillar. It follows a cashew nut from the nursery to the global shelf, names every actor who touches it, and shows exactly where the money is made and lost along the way. Ghana grows a large, good crop but captures a small slice of its value, because the chain leaks at three joints: the raw-export gap, the aggregation layer and quality. Understanding those three joints is understanding the whole business.

The one-paragraph thesis is this. About nine in ten raw nuts leave Ghana unshelled for India, Vietnam and the UAE, so the country banks the raw price of roughly US$500 a tonne rather than the US$20,000 to 40,000 a tonne that the finished kernel earns at retail (IMANI Africa, 2025). Value leaks at three joints: the raw-export-against-processing gap, where only about 6 to 10 percent is processed at home; the aggregation layer, where below-floor buying and layered fees erode the farmer's share; and quality shortfalls that pull down the realised price. The good news is that the tools to fix all three, cooperatives, the commodity exchange, contracts, certification and processing, are now at least partly live in policy.

🌰 The whole chain in one view: the crop grows here, the value is added there

Figure 6.1 The Ghana cashew value chain from farm to global shelf, with the governance and value-ladder overlays

What this shows

The nut moves from farm to global shelf while the largest margins are added abroad, and the structured market and the value-ladder overlays show where an entrant can capture value that currently leaves the country raw.

The master table below reads the same chain a second way, as a business. For each link it names who actually operates it, the price or margin that moves through it, where the value leaks or the link breaks, and the opening that sits inside that break. It is the analytical spine of this pillar; every section that follows expands one of its rows.

Lay the chain out link by link and the shape of the problem is immediate. It runs: inputs of planting material, agrochemicals, tools and sacks, into production on about 200,000 mostly smallholder farms in the Bono, Bono East and Ahafo transition zone, into a crowded aggregation layer of buying agents, licensed buying companies and traders, into a fork where a small share is processed at home and the rest is bulked for export, into consolidation and shipment through Tema port, and finally into the shelling and retail that happen overseas where the kernel earns its largest margin.

A more transparent channel is now branching off in the middle: the Ghana Commodity Exchange trades cashew through a graded, weighed, warehouse-receipt system with auction price discovery. The one fact that reshapes everything is that market power sits with the regulator, the government and the foreign buyers who shell the nuts, while the roughly 200,000 farmers who carry the crop hold the least influence (World Bank, 2023). Ghana exports a raw nut worth about US$500 a tonne; the kernel, the roast and the retail pack are all added and captured offshore.

Table 6.1: The cashew value chain read as a business: who earns, where it breaks, and the opening in each break
Chain link	Who operates it	Margin or price signal	Where it breaks	The opening
Inputs and nurseries	Nurseries, agro-dealers, CRIG and CSIR research	Grafted seedlings scarce; no large seed company	Quality planting material is the binding constraint	Certified grafted-seedling supply and agronomy (Pillar 1)
Production, the orchard	About 200,000 farmers, 88 percent smallholders	About 500 kg/ha against about 1,100 in Vietnam	Low yield; a four-month harvest window	Yield uplift, out-grower support and inputs
Aggregation	Buying agents, licensed buying companies, traders	Some pay GH¢8 to 10 a kilogram, below the floor	Oligopsony; the farmer only decides whether to sell	Cooperative aggregation and price transparency
Structured market	GCX, TCDA, WFP and ADB warehouses	Graded, weighed, auction price discovery	Still thin; the floor must stay dynamic	Warehouse-receipt aggregation and finance
Processing	ACPG processors, about 80 percent women workers	Only 6 to 10 percent processed at home	Largest plant runs at about a fifth of capacity	Domestic shelling at scale (Pillar 5)
Raw export	Exporters, LBCs, Tema port	About 90 percent exported raw at about US$500 a tonne	The biggest margin is handed to foreign shellers	Shell at home; sell kernels past the middle
Global kernel market	India and Vietnam shellers; EU and US roasters	Retail about US$17/kg; 85 percent of shelling in two countries	The largest margin sits offshore	Certified, traceable kernels into the premium shelf

WHAT THIS MEANS. Read the table top to bottom and the sector's whole problem is one sentence: Ghana grows the crop but adds almost none of its value, and hands the biggest margin to foreign shellers at the fork. Every row breaks at the point where grading, transparent pricing, shelling or traceability should sit and does not. That is not a list of problems, it is a list of businesses nobody is running at scale. The rest of this pillar is those businesses.

🌰 Stage 0 to 1: inputs and production, where the crop starts light

Inputs and the orchard

The chain begins with planting material, agrochemicals, tools and sacks, and its first constraint is quality planting material. There is no large seed company supplying grafted seedlings, so nurseries are few (USDA, 2012; African Cashew initiative, 2011). Production sits with about 200,000 farmers (Conseil International Consultatif du Cajou, 2023), roughly 88 percent of them smallholders with 0.8 to 3.0 hectares, concentrated in the Bono, Bono East and Ahafo transition zone, and harvesting for only about four months from February to May (African Cashew initiative, 2010; World Bank, 2023).

Productivity is the quiet leak at this end. Ghana averages about 500 kilograms a hectare against about 1,100 in Vietnam (World Bank, 2023), so the orchard enters the chain carrying less than half the crop it could. The opening here is certified grafted-seedling supply, yield-raising agronomy and out-grower support, all of which de-risk everyone downstream and take far less capital than a processing plant (Pillar 1).

🌰 Stage 2: aggregation, where the farmer's share is decided

Some pay below the floor

The crowded middle: buying agents move farm to farm and set the price the farmer must take or leave.

This is the crowded, value-leaking middle, and it is where the farmer's share is decided. Buying agents move farm to farm for licensed buying companies, traders and processors, aggregators bulk the nuts, and the market behaves as an oligopsony in which, as the World Bank puts it, buyers hold the market power and farmers can only decide whether to sell at the price offered (World Bank, 2023).

It is here that some aggregators pay as little as GH¢8 to 10 a kilogram in parts of the 2024/25 season, below the price floor (Business and Financial Times, 2024 to 2025). The counterweight is farmer organisation: cooperatives that bulk and sell together negotiate better prices, and a new Bono Cashew Farmers' Cooperative Union was inaugurated in 2025 (World Bank, 2023; Ghana News Agency, 2025). Notably, the farm-gate buying role is itself dominated by women (van den Berg, 2015).

🌰 Stage 2B: the structured market, a more transparent channel

A more transparent channel is emerging alongside the farm-gate trade. The Ghana Commodity Exchange, with the Tree Crops Development Authority, has begun trading cashew through a graded, weighed, warehouse-receipt system with auction price discovery, backed by UNIDO grading equipment, a World Food Programme warehouse and Agricultural Development Bank warehouse-receipt finance.

The model is proven elsewhere. After Tanzania introduced a cashew warehouse-receipt system, the farmer's share of the export price rose sharply and lending against receipts flowed (UNCTAD, 2009). The lesson for Ghana is to keep the price floor dynamic and publish auction results, because a rigid floor once left 90,000 tonnes unsold in Tanzania (Food and Agriculture Organization, 2015).

🌰 Stage 3: the split, processing against raw export

Here the chain forks, and the fork is where Ghana hands the biggest margin abroad. Only about 6 to 10 percent of the crop is processed at home, kernel output was about 15,000 tonnes in 2025 (African Cashew Alliance, 2025), about 80 percent of processing workers are women (World Bank, 2023), and the largest plant runs at about a fifth of capacity (IMANI Africa, 2025).

The other roughly 90 percent is exported raw, mainly to India and Vietnam, through Tema port. The processing economics and the reasons for the gap are set out in Pillar 5; the value-chain point is that the fork itself is where the six-fold kernel margin and the retail premium leave the country, because the nut that could be shelled here is shipped out whole instead.

Third-largest raw exporter

Through Tema: the raw nut ships out whole, and the shelling and the kernel margin happen overseas.

At export, nuts are consolidated at Tema under a TCDA regime that now requires a written TCDA permit to export unprocessed cashew since 2 May 2025 (Tree Crops Development Authority (L.I. 2471), 2025) and charges a TCDA development levy of GH¢44.86 a tonne of raw nuts (Tree Crops Development Authority, 2025). Ghana is the third-largest raw cashew nut exporter in the world (International Trade Centre, 2024).

Overseas, India and Vietnam shell the nuts and re-export the kernels to Europe and the United States, where roasters and retailers take the largest margin of all. About 85 percent of the world's shelling sits in those two countries (International Trade Centre, 2024). The destination map is the shape of the dependence, and the reason a Ghanaian sheller who reaches past it captures value the chain now exports whole.

The demand side of this same story, where the raw nut actually lands and what a graded kernel is worth once it is shelled, is mapped in full in Pillar 2: its destinations chart traces the raw-export routes into India, Vietnam and the UAE, and its kernel-grades chart sets out what a whole W240 earns against a broken piece. The value-chain point stands regardless of the detail: both journeys, the nut's destination and the kernel's grade, happen almost entirely outside Ghana, which is exactly why the Stage 3 fork above matters so much.

🌰 Following the money: who keeps what

The farmer's share shrinks down the chain: about 65 percent of the raw-export price but only 16 percent of the retail kernel price — Figure 6.2 The farmer's share shrinks down the chain: 65 percent of the raw-export price, only 16 percent of retail

What this shows

The farmer keeps a fair share of a small raw pie, about 65 percent, but only about 16 percent of the large processed pie, because the processing and retail value is added and captured offshore.

Put the stages together and the distribution of value is stark. On the raw-export channel the farmer keeps about 65 percent of the free-on-board price (World Bank, 2023), but on the processed-kernel channel the farmer keeps only about 16 percent of the retail price (World Bank, 2023), with the processor and the retail end taking the rest.

The classic price ladder shows the same story per kilogram: farm-gate raw nuts at about US$0.52 a kilogram, a shelled kernel at about US$6.80, a roasted kernel at about US$10 and packaged retail at about US$17 (African Cashew initiative / GIZ, 2010). The climb is steep, and almost all of it happens after the nut leaves Ghana.

The bottom rung: from this scale, the price climbs steeply all the way to the retail shelf.

What this shows

Each step from raw nut to shelled, roasted and packaged kernel multiplies the price, and the largest jumps sit at the shelling and retail steps that happen outside Ghana; Pillar 5's value-ladder chart tracks the same climb from the processing-economics side.

The price ladder, rung by rung

Table 6.2: The cashew price ladder from farm gate to retail shelf: the farmer stands on the lowest rung
Rung on the ladder	Who stands here	Price per kilogram	What it means
Farm gate, raw nuts	The farmer sells	About US$0.52 a kilogram	The thinnest slice, on a crop held all year
Aggregation	Buying agents and traders	Some buy GH¢8 to 10/kg, below the floor	Margin captured without much value added
Shelled kernel	A foreign processor shells	About US$6.80 a kilogram	The six-fold jump Ghana mostly exports away
Roasted kernel	A roaster adds value	About US$10 a kilogram	Value added abroad, not at home
Packaged retail	The retailer, EU and US shelf	About US$17 a kilogram	The largest margin of all, furthest from the farm

Sources: African Cashew initiative / GIZ (2010); World Bank (2023).

WHAT THIS MEANS. The two numbers, 65 percent and 16 percent, are the whole argument for processing and organisation in one line. When Ghana exports raw, the farmer actually keeps a fair share of a small pie. When the pie is made bigger by processing, almost all of the extra value currently leaves the country. The prize is not just to process more, but to process in Ghana and to organise farmers so the larger pie is shared at home rather than offshore.

🌰 The quality-premium mechanism: a market that does not yet reward quality

A market that does not yet reward quality is the third leak. A 2026 study of 401 farmers and 278 buyers in the Bono and Savannah regions found that about 65 percent of farmers would accept a premium for quality and 58 percent of buyers would pay one, yet the premium rarely gets paid (Anaman et al., 2026).

The reason is an information and enforcement failure. Only about 43 percent of farmers know the international quality standards, only a handful understand kernel outturn or nut count, and when buyers keep purchasing sub-standard nuts, farmers learn that quality is not rewarded. Fixing this, with clear quality protocols and outturn-based pricing at every buying point, is one of the highest-return, lowest-cost interventions in the whole chain.

Grading decides the premium

Where quality is judged: the outturn a nut delivers here is what a buyer should pay for, and rarely does.

What this shows

How a nut is dried, sorted and stored decides its outturn and grade, so the post-harvest steps are where the quality premium is won or lost before the nut ever reaches a buyer; Pillar 3's post-harvest handling steps walk through drying, sorting and storage in full.

🌰 Designing better offtake: contracts and outgrower schemes

Jute bags of raw cashew nuts bulked and ready for sale, the volume a production contract secures for an offtaker

97.6 percent of contracts verbal

How you sell matters: a written production contract that bundles inputs with a market lifts yield where a marketing-only deal does not.

How a farmer sells matters as much as what a farmer grows. About 45 percent of cashew farmers use contract farming, but 97.6 percent of those contracts are verbal (Dubbert, 2019). Where contracts are used, the effect is large: participating farmers saw yields, net revenues and price margins all rise by a third or more, with small farms gaining most.

The contract type matters, though. Production contracts that bundle inputs with a market beat marketing contracts that offer only a market, because a secure buyer alone does not lift productivity (Dubbert & Abdulai, 2021). Nucleus-outgrower schemes, in which a resourced farmer supplies smaller farmers with training and inputs, raise smallholder profitability and are the template to copy.

ACTION POINTS. For an aggregator or offtaker, do not just offer to buy. Offer a production contract that bundles certified seedlings, inputs, extension and a graded, outturn-based price, ideally through a cooperative and the commodity exchange. That is what actually lifts farmer yield and quality, secures your supply, and earns the premium the market is willing to pay but the chain currently fails to deliver.

🌰 Who sets the rules, and who does the work

Governance and the partner network

The chain is governed by the Tree Crops Development Authority, which licenses aggregators, traders and exporters, sets the minimum price and the export reference, charges the levy and runs a farmer passbook and conveyance-certificate system. Around it sit industry bodies, the Cashew Council Ghana, the Cashew Industry Association of Ghana and the Association of Cashew Processors Ghana, and an advocacy layer in Cashew Watch Ghana.

A dense development-partner network supports the chain, including GIZ and ComCashew, the African Cashew Alliance, USDA programmes, UNIDO, the World Food Programme and the World Bank; ComCashew alone reports training more than 45,000 Ghanaian farmers (ComCashew, 2024).

Women do most of the cashew chain's work but hold little of the ownership, and the processing group is the lever that changes it — Figure 6.3 Women do most of the work but hold little of the ownership; the processing group is the lever

What this shows

Women carry most of the harvest and processing labour but hold a small fraction of the farms and factories, so the processing group is the lever that turns their work into ownership.

One structural fact runs through the whole chain. Women make up about 80 percent of harvest labour and more than 80 percent of the processing workforce, yet own under 10 percent of farms and under 5 percent of factories (GIZ gender study; World Bank, 2015 to 2023). Women do most of the work but hold little of the ownership, blocked mainly by customary land tenure.

The lever that works is the processing group. Women in cashew-processing groups earn substantially more and reinvest it (van den Berg, 2015). Any serious upgrading plan has to put land access, group organisation and processing ownership for women at its centre, both because it is fair and because it is where the labour and the diligence already are.

🌰 The actors and who holds the power: a stakeholder map

A value chain is also a map of power. The figure below places every actor by how much power it holds over the chain against how much interest it has in the cashew business, and the pattern it shows is the root of Ghana's value leak.

Power sits with the regulator, the government and the foreign buyers who shell the nuts; the roughly 200,000 farmers and their cooperatives, who carry the most interest, hold the least influence, and the aggregation layer in the middle captures margin without adding much value (World Bank, 2023). An entrant's task is to move actors up and to the right, by organising farmers, processing at home, or plugging into the structured market, so that more of the power, and the margin, is held inside Ghana.

The cashew stakeholder power-interest map: power sits downstream and with the regulator, while farmers hold high interest but little power — Figure 6.4 The cashew stakeholder power-interest map: power sits downstream and with the regulator

What this shows

Power sits downstream and with the regulator, while farmers hold high interest but little power, so the aggregation layer captures margin in the middle without adding much value.

Table 6.3: The cashew value-chain actors, their power and interest, and what each means for a new entrant
Actor	Role in the chain	Power	Interest	What it means for an entrant

MARKET SIGNAL: WHO AN ENTRANT MUST ALIGN WITH. Who an entrant must align with. The two quadrants that decide a cashew venture are the high-power actors, the TCDA, government and the buyers who must be managed closely, and the high-interest, low-power actors, the farmers and cooperatives who must be organised. A defensible business does both at once: it complies with and uses the regulator, and it builds the farmer organisation that shifts power, and margin, back up the chain.

🌰 The upgrading levers: how Ghana closes the gap

With the leaks mapped, the upgrading levers follow directly, and each attacks a joint. Cooperative aggregation lifts the farm-gate price and opens access to premiums, the Bono union being the current model. The commodity exchange and warehouse receipts bring grading, price discovery and receipt-backed finance that cut out intermediaries and reward quality.

Production and outgrower contracts raise yield and quality where marketing-only contracts do not. Traceability and certification, organic, Fairtrade and sustainability schemes, unlock the EU premium and formalise Ghana's large chemical-free supply. Domestic processing captures the six-fold kernel and thirty-fold retail multiple, given scale, finance and year-round feedstock, and by-product valorisation, cashew nut shell liquid and cashew-apple products, adds revenue lines and cuts processing cost (Pillar 5).

Pillar 7 plots each of these openings on a single opportunity chart, the capital it needs against the return it offers; cooperative aggregation and a grading service sit low on capital and high on return there, while domestic processing at scale is the capital-heavy prize that captures the kernel and retail multiple. The table below carries that same ranking through in full operational detail, opening by opening.

Not every lever is equally easy to pull. The table below ranks the value-capture openings by how wide the gap is against how much capital and coordination it takes to enter, so an entrant can see where to start rather than simply that the field is open.

Table 6.4: The value-capture openings ranked: where the gap is widest against what it takes to enter
Value-capture opening	Why the gap exists	Capital and difficulty	Rank
Cooperative aggregation and warehouse receipts	Oligopsony; below-floor buying; opaque price	Moderate; a group, a warehouse and an offtake	1 - clearest, most repeatable
Grading and quality-assurance service	The market does not yet reward quality; 43 percent know standards	Low; skills over capital	2 - low cost, high return
Production and outgrower contracts	97.6 percent of contracts verbal; input-plus-market lifts yield	Moderate; inputs, extension and offtake	3 - secures supply and quality
Traceability and certification	EU and organic premium unclaimed on a large chemical-free supply	Moderate; systems and audit	4 - unlocks the export premium
Domestic processing at scale	Only 6 to 10 percent shelled at home; largest plant at a fifth of capacity	High; plant, finance and feedstock	5 - biggest prize, capital-heavy
By-product valorisation, CNSL and cashew apple	Shell liquid and the cashew apple are largely wasted	Moderate; tie to a processing line	6 - a second revenue line

WHAT THIS MEANS. Start where the gap is wide and the capital is modest, then climb. Cooperative aggregation and a grading service need skills and organisation more than capital, and they attack the two joints, aggregation and quality, that decide the farmer's share. Contracts and certification follow as the supply base is secured. The capital-heavy prize, domestic processing at scale, is where a well-financed player or a public-private partnership should aim, because it captures the kernel and retail multiple the chain now exports (Pillar 5).

MARKET SIGNAL: AI AND THE DIGITAL OPENING. AI and digital opening. Every joint where the chain leaks has a digital fix. Feasible now: digital aggregation and sourcing platforms that give farmers a graded, transparent price, one of which already reached about 5,400 farmers with better prices (World Bank, 2023), the Ghana Commodity Exchange's electronic warehouse receipts, the TCDA's digital passbook and conveyance certificate, and traceability apps that carry the origin and quality record the EU and organic buyers now demand. Ghanaian platforms such as AgroCenta and Complete Farmer already run digital sourcing, payment and logistics. Blockchain traceability at export scale is commercial-only for now. The opening is a traceable, receipt-backed aggregation business (Pillar 7).

🌰 The Opening: build the bridges that keep the value at home 🌰

01

Cooperative aggregation and warehouse receipts. The single most repeatable opening. Bulk selling lifts the farm-gate price, and a warehouse-receipt operation grades, stores and finances nuts so farmers can borrow against stored stock, cutting out the below-floor buyer the aggregation layer now runs on (World Bank, 2023; UNCTAD, 2009).

02

Production and outgrower contracts. An input-plus-market contract that bundles certified seedlings, inputs and extension with a graded, outturn-based price raises yield, net revenue and margin by a third or more, with small farms gaining most, where a marketing-only contract does not (Dubbert & Abdulai, 2021).

03

Process at home and claim the certification premium. The kernel earns roughly six times the raw nut and the retail pack many times more, and Ghana's large chemical-free supply is ready for the organic and Fairtrade premium the EU now pays; shelling at home is the way to keep that value in the country (African Cashew initiative / GIZ, 2010; IMANI Africa, 2025).

🌰 The risks that sit inside the value chain 🌰

Aggregator power and below-floor buying

HIGH

What it is

The aggregation layer is an oligopsony. Buyers hold the market power and the farmer can only decide whether to sell at the price offered, and some agents pay below the legal floor, so the farmer's share erodes at the very joint where it is decided.

Evidence

The World Bank finds buyers hold the market power while farmers only decide whether to sell, and some aggregators paid as little as GH¢8 to 10 a kilogram against the floor in the 2024/25 season (World Bank, 2023; Business and Financial Times, 2024 to 2025).

Who it hits

Unorganised smallholders selling one buyer at a time at the farm gate.

How to manage it, and the opening

Organise into cooperatives and trade through the commodity exchange; the opening is a cooperative aggregation and warehouse-receipt business that grades, weighs and finances the crop.

A market that does not reward quality

MEDIUM-HIGH

What it is

When buyers keep purchasing sub-standard nuts, farmers learn that quality is not paid for, so the whole chain stays low-grade even though both sides say they want a premium.

Evidence

About 65 percent of farmers would accept a premium for quality and 58 percent of buyers would pay one, yet it rarely happens, and only about 43 percent of farmers know the international quality standards (Anaman et al., 2026).

Who it hits

Farmers who invest in quality but are not rewarded, and buyers who cannot source a consistent grade.

How to manage it, and the opening

Introduce outturn-based pricing and clear quality protocols at every buying point; the opening is a grading and quality-assurance service, one of the highest-return, lowest-cost interventions in the chain.

Ghana as a raw-nut price-taker

HIGH

What it is

About nine in ten nuts leave the country unshelled, so Ghana banks the raw price and hands the six-fold kernel margin and the retail premium to foreign processors. The country is the third-largest raw exporter in the world and one of the smallest kernel sellers.

Evidence

Roughly 90 percent of the crop is exported raw at about US$500 a tonne, only 6 to 10 percent is processed at home, and about 85 percent of the world's shelling sits in India and Vietnam (IMANI Africa, 2025; World Bank, 2023; International Trade Centre, 2024).

Who it hits

The whole sector, which forgoes the kernel and retail value, and the processing workers, about 80 percent of them women, whose plants run far below capacity.

How to manage it, and the opening

The opening is domestic shelling at scale with year-round feedstock and finance, and certified kernels sold past the foreign sheller into the EU and US premium (Pillar 5).

Verbal contracts and no secure offtake

MEDIUM

What it is

How a farmer sells matters as much as what a farmer grows, yet most selling is spot and papers-light, so neither the farmer nor the buyer can plan, invest or borrow against the relationship.

Evidence

About 45 percent of cashew farmers use contract farming, but 97.6 percent of those contracts are verbal, and production contracts that bundle inputs with a market beat marketing contracts that offer only a market (Dubbert, 2019; Dubbert & Abdulai, 2021).

Who it hits

Farmers who cannot access inputs or credit, and offtakers whose supply is never secure.

How to manage it, and the opening

Offer a written production contract that bundles certified seedlings, inputs and extension with a graded, outturn-based price, ideally through a cooperative and the exchange; it lifts yield and quality and secures the supply.

Buyers set the price

The market is an oligopsony: farmers can only decide whether to sell at the price offered.

Quality goes unpaid

Both sides say they want a premium, yet the chain keeps buying sub-standard nuts.

About 90 percent leaves raw

Ghana banks the raw price of about US$500 a tonne and exports the kernel margin away.

🌰 Key takeaways 🌰

01

The chain leaks at three joints: raw export, aggregation and quality. Fix those three and Ghana keeps the value it now sends offshore.

02

The farmer keeps about 65 percent of a small raw pie but only about 16 percent of the large processed pie, and almost all the processed value currently leaves the country (World Bank, 2023).

03

About nine in ten nuts leave Ghana raw at roughly US$500 a tonne, while the finished kernel earns US$20,000 to 40,000 a tonne at retail; the prize is to process at home (IMANI Africa, 2025).

04

Women do most of the work, about 80 percent of harvest labour and more than 80 percent of processing, but own under 10 percent of farms and under 5 percent of factories; any upgrading plan must put women's ownership at its centre (GIZ; World Bank, 2015 to 2023).

05

The tools to fix the chain are known and now partly live: cooperatives, the commodity exchange with warehouse finance, input-plus-market contracts, certification and domestic processing. Whoever builds these bridges captures the value that now flows offshore.

Where this connects. This chain begins with the planting material and yield gap of Pillar 1, which is why certified seedlings recur here as the first input constraint; its processing economics, the six-fold kernel margin and the by-product lines, are worked through in Pillar 5; and the policy tools that could close its three joints, the raw-export permit regime, the commodity exchange and the finance rails, are set out in Pillar 7.

🌰 Practitioner intelligence 🌰

Hover any card to pause and lift it.

For students

The value leaks in the middle of the chain, and that is where a graduate fits with skills rather than capital: a grading and quality-assurance service, or a cooperative-linked aggregation and warehouse-receipt operation. Learn to grade nuts and to run a warehouse receipt so farmers can borrow against stored stock. The trap is entering as one more small aggregator competing on price; enter instead as the person who brings the grading, transparency and finance the current buyers do not.

For entrepreneurs

First move: aggregate through a cooperative and the commodity exchange rather than buying farm to farm, so you can offer a graded, transparent, outturn-based price and access warehouse-receipt finance. Secure the farmer group, a warehouse and an offtake before you buy a single bag. The trap is paying below the floor to win volume, which the enforcement drive now punishes and which no premium buyer will source from; win on reliability and grade instead.

For investors

Diligence asks where in the chain the venture sits and what stops the margin leaking past it, whether it uses production contracts that bundle input plus market rather than only spot buying, and whether it can prove the farmer's share and the outturn it delivers. Value is captured by whoever processes at home or organises farmers, and lost by everyone who only moves raw nuts. Structure the cheque around a contracted supply base and warehouse-receipt collateral, and underwrite the aggregation-layer price and enforcement risk.

For faculty

Assignment: have students trace one tonne of raw nuts through the chain using the World Bank value-distribution data, calculating the farmer's share on the raw-export channel against the processed channel, and identify the single biggest leak. Deliverable: a value-distribution diagram and a memo recommending one upgrading lever. It teaches where power and margin sit in an agricultural value chain, and why.

For ecosystem actors

The lever is to strengthen the structured market and farmer organisation: capitalise the commodity exchange and warehouse-receipt system, enforce the farm-gate floor, and back cooperatives and production contracts. Measure success by the farmer's share of the free-on-board price and by the volume traded through graded, receipt-backed channels. The failure to avoid is a rigid, politically set floor decoupled from the auction, which, as in Tanzania, can leave the crop unsold (Food and Agriculture Organization, 2015).
