Post-Harvest Loss: What Is a Bumper Harvest If It Ends in Silence?

As Ghana’s farmers ready themselves for the coming harvest season, there is an air of cautious optimism across the countryside. The rains, though sometimes uneven, have largely been good. The fields are thick with maturing maize, the yam vines are vigorous, and vegetables are filling up baskets in local markets. For policymakers watching inflation figures edge downward after last year’s painful highs, there is a shared hope that this season will deliver the relief many Ghanaians desperately want: cheaper food, calmer markets, and some breathing room for household budgets.

But beneath this optimism lies a quiet, persistent crisis, one that has repeated itself season after season with little meaningful change. For all the hope of a bumper harvest, there is no guarantee that the abundance in the fields will ever fully reach the people who need it. Each year, as much as 20 to 30 percent of Ghana’s harvested crops are lost before they even arrive in markets. This waste, largely invisible to urban consumers who see only the final price tags on stalls, represents a silent drain on national food security, a hidden driver of stubborn food inflation, and a painful betrayal of farmers’ hard work.

The true scale of the problem came into even sharper focus with a 2023 report published by the Embassy of Denmark, which estimated that Ghana loses an astonishing $1.9 billion worth of food annually to post-harvest losses and waste. This is not an abstract number. It is grounded in the daily struggles of farmers who see their work and investment vanish in the gap between harvest and market. The study revealed that yam alone accounts for over $560 million in annual losses, highlighting both the importance of the crop and the magnitude of the challenge. Mango losses were estimated at $300 million, while tomatoes, a staple in kitchens across the country, were responsible for over $60 million in losses each year.

These figures are not just statistics on a page,they are a stark reminder that even when the land is generous, Ghana’s food system remains deeply vulnerable. The hope of abundance risks being squandered if what is grown cannot be preserved, moved, stored, and sold efficiently. For all the optimism of the coming harvest, there remains the pressing question: can Ghana finally keep what it grows?

Across farming communities, the reality of post-harvest loss is well known, even if it rarely dominates national headlines. When the harvest is good, farmers often find themselves flooded with produce all at once. They must sell immediately or risk watching their bounty spoil in the heat. There are too few modern warehouses or silos to store the surplus safely. For those growing cereals like maize or sorghum, storage often means a makeshift shed or an old room in the house, vulnerable to weevils and mould. For vegetable farmers, the challenge is even more unforgiving. Without refrigerated trucks or cold rooms, ripe tomatoes and peppers can turn to mush in days under the Ghanaian sun.

Transporting crops from farm to market poses its own challenges. Many of Ghana’s feeder roads remain in poor condition, especially after the heavy rains that make farming possible in the first place. Trucks and buyers may simply refuse to travel certain routes when they are muddy or washed out. Even when they do come, transport costs can be painfully high, eating into the already narrow margins farmers make. Middlemen, knowing farmers are desperate to sell quickly, often dictate prices. Without viable alternatives or cooperatives with bargaining power, farmers frequently have no choice but to accept these terms.

What all this means is that Ghana’s apparent abundance can be deceptive. While fields may be green and harvest bins full in August and September, much of that food never feeds people. It rots on the farm or is sold at such low prices that farmers cannot reinvest in the next season. In urban markets, meanwhile, the cost of transporting, storing, and handling what does arrive keeps retail prices higher than they ought to be. Even with a so-called bumper harvest, the promised relief for consumers can prove fleeting.

This is not a new problem. Experts have been warning for decades about post-harvest loss in Ghana. Studies routinely estimate losses of 20 to 30 percent overall, with perishables sometimes seeing losses as high as 50 percent. In real terms, this means hundreds of millions of dollars in wasted value every year. That is food that could lower prices, feed more people, and reduce imports. It is also money lost for farmers, money they could use to send children to school, pay for healthcare, or invest in better seeds and tools.

The impact goes beyond economics. Wasted food is wasted water, land, fertilizer, and labour. It represents an environmental cost that Ghana, like the rest of the world, cannot afford to ignore. It also means the country’s fight against food inflation, a battle that has defined economic policy debates in recent years, is being undermined from within its own food system.

The solutions, many argue, are not mysterious. Ghana needs better storage infrastructure, from modern grain silos in farming hubs to small, affordable on-farm storage technologies like hermetic bags and metal silos. Cold-chain development is critical for fruits and vegetables. That means investing in refrigerated trucks, cool rooms at collection centres, and power solutions that work even in off-grid communities.

Road infrastructure remains another vital piece of the puzzle. Improving feeder roads is not just about making life easier for farmers. It is about ensuring that what is grown can actually move to market quickly and affordably. In many communities, a single bad bridge or washed-out section of road can cut off entire farming areas from buyers at harvest time.

Processing capacity is equally important. If farmers can turn surplus tomatoes into paste, or cassava into flour, they gain a buffer against price crashes and spoilage. Local processing can create jobs, add value, and stabilize markets. Yet Ghana’s agro-processing sector remains underdeveloped outside of a few flagship initiatives.

Then there is the human factor. Agricultural extension services have improved over the years, but many farmers still lack access to reliable training on post-harvest handling. Knowledge about drying, sorting, pest control, and packaging can make a real difference. Yet training alone cannot fix problems if farmers cannot afford or access the tools and infrastructure they need to act on that knowledge.

Policymakers have not ignored these issues entirely. Programs like the Planting for Food and Jobs initiative have tried to boost production, and the National Food Buffer Stock Company aims to buy and store surplus to stabilize prices. But funding, coordination, and follow-through have often fallen short of what is needed to address the scale of the problem.

This harvest season, expectations will once again be high. Inflation has been dropping in recent months, and many will look to the fields for further relief. There is reason for hope: good rains and hard-working farmers can indeed produce plenty. But the real question is whether Ghana can finally solve the problem of getting that abundance safely and efficiently from the farm gate to the dinner table.

Without tackling post-harvest loss, the promise of the harvest will remain fragile. Food prices may dip briefly, only to surge again when the glut ends and scarcity returns. Farmers will continue to lose income. Consumers will continue to pay too much. And the cycle will repeat.

In the end, fighting food inflation is about much more than growing more. It is about building the systems that ensure what is grown is saved, stored, transported, processed, and sold fairly. It is about making sure that a good harvest truly means good food for everyone. That is a test Ghana cannot afford to keep failing.

As the country now prepares to enter into the bumper harvest season, there is hope in the fields and anticipation in the markets. But hope alone is not enough. The promise of abundance must be matched by the commitment to preserve it. Post-harvest loss is not simply an unfortunate side effect of farming life, it is a cost Ghana no longer has to pay. It is a cost the nation can no longer afford to ignore.

Because if Ghana can save what it grows, it can feed its people more securely, fight inflation more effectively, and build a food system that truly rewards the labour of its farmers while nourishing every household. This harvest season offers a chance to do just that, not just to grow more, but to keep more, and to ensure that abundance reaches every plate.
