Cocoa Processing Plant versus Rural Investment
Cameroon exports about 300,000 tonnes of cocoa beans a year, but only 25% is processed locally. Raw beans sell at about 1,500 FCFA/kg. A tonne of beans processed into butter, liquor and powder sells for a combined 2.8 million FCFA, and processing costs about 900,000 FCFA per tonne of beans. A proposed grinding plant would cost 120 billion FCFA, employ 800 workers and process 60,000 tonnes a year. It would import machinery and rely on a grid with frequent outages. Smallholders receive less than half of the final export price, and youth unemployment in the region is above 20%. The government can subsidise the plant or invest the same 120 billion FCFA in rural roads, extension services and storage. World cocoa prices are volatile, and a neighbouring country is also expanding processing capacity.
1. Using the figures, calculate the annual gross value added from processing 60,000 tonnes of beans, before deducting the plant's capital cost. What does this imply about the payback period?
Read the worked answer
Raw bean value = 60,000 t × 1.5m FCFA/t = 90bn FCFA. Processed revenue = 60,000 × 2.8m = 168bn. Processing cost = 60,000 × 0.9m = 54bn. Gross value added before capital cost = 168 − 90 − 54 = 24bn FCFA per year, assuming full capacity, no waste and no financing cost. The plant costs 120bn, so simple payback = 120/24 = 5 years. That looks acceptable, but it ignores construction delays, energy outages, working capital, taxes, depreciation and the risk that world prices fall. If the plant runs at 60% capacity, value added falls to about 14.4bn and payback stretches to over 8 years. The calculation also values the beans at the export price, so the gain comes from the processing margin, not from extra cocoa output.
2. Explain two ways in which the plant could fail to deliver the expected development benefits, and relate them to the concept of Dutch disease or enclave development.

First, the plant could become an enclave: 120bn of capital employs only 800 workers, machinery is imported, and most profits may be repatriated. The link to smallholders is weak if the plant buys through large traders. Second, Dutch disease risk: if processing raises export earnings and attracts foreign exchange, the real exchange rate may appreciate and make other tradable sectors, such as food crops or light manufacturing, less competitive. Third, energy outages can raise costs and reduce output, wiping out the processing margin. Fourth, world cocoa prices are volatile; a fall in the processed price or a rise in the bean price can turn the 24bn margin negative. The plant may also compete with existing processors for beans, raising raw bean prices for smallholders but squeezing margins. Development benefits are not automatic; they depend on linkages, skills, local sourcing and reinvestment.
3. Advise the government on how to choose between the plant and rural investment. Your answer should consider opportunity cost, risk and distribution.
Read the worked answer
The government should compare the plant with the rural package on opportunity cost, risk and distribution. The plant offers 24bn annual value added and 800 formal jobs, but requires 120bn, imported equipment and reliable power; its benefits are concentrated and its payback is sensitive to prices. Rural roads, extension and storage may cost less per beneficiary, raise yields for many smallholders, reduce post-harvest losses and spread risk, but they may have lower direct export earnings and slower visible returns. A hybrid is likely best: use part of the 120bn to fix energy and quality infrastructure, offer a conditional subsidy or public-private equity to the plant only if it contracts with smallholders and meets local sourcing targets, and fund roads and storage in the same zone. The government should publish cost-benefit analysis, use competitive tenders, and build in review points. Distribution matters: the plant's 800 jobs are fewer than the many smallholder livelihoods affected by cocoa prices, so a pure plant subsidy may worsen inequality unless accompanied by farmer-level support.
