Tomato post-harvest losses significantly affect small farmers in Africa and South America. These losses often lead to 40–50% of the crop being wasted. These loses often occur due to poor storage, transport, and handling. The losses reduce income, limit access to markets, and discourage farmers from scaling their production.
At Wise Farmer, we believe small commercial farmers can cut losses and increase profits by adopting simple, affordable storage and drying techniques.
The Problem: Why Tomato Losses Happen
- Short shelf life – Fresh tomatoes spoil quickly in hot climates.
- Poor handling – Bruising during harvest and transport accelerates rotting.
- Lack of cold storage – Many rural farmers lack access to refrigeration.
- Market delays – Oversupply during harvest season lowers prices and forces waste.
Solution 1: Improved Harvesting & Handling
- Harvest at the right stage – Harvest tomatoes when slightly firm and mature, not overripe.
- Use clean, ventilated crates – Replace woven baskets that squash and bruise tomatoes.
- Shade during transport – Keep tomatoes out of direct sun to extend freshness.
Solution 2: Low-Cost Storage Techniques
- Evaporative cooling chambers (Zero Energy Cool Chambers) – Made from bricks, sand, and water; reduces temperature and extends shelf life by up to 7 days.
- Clay pot coolers – Simple pot-in-pot systems that use evaporation to keep tomatoes fresh longer.
- Plastic crates – Durable and stackable, they reduce damage compared to sacks.
Solution 3: Drying & Processing Tomatoes
- When fresh markets are saturated, processing is the best way to save value.
- Sun drying – Spread sliced tomatoes on raised, clean mats or mesh under the sun. Cover with mesh to keep insects away.
- Solar dryers – Affordable, small-scale dryers that reduce contamination and improve drying speed.
- Value-added products – Sun-dried tomatoes, tomato powder, and homemade paste have longer shelf lives and sell at higher margins.
Example: A farmer in Nigeria converted excess tomatoes into dried flakes, extending shelf life by 6 months and selling at 4x the fresh price.
Solution 4: Organizing for Scale
- Farmer cooperatives – Pooling resources allows small farmers to build shared storage or buy small solar dryers.
- Market linkages – Partner with retailers, hotels, and food processors for off-season sales.
- Training & support – Learning low-cost post-harvest methods ensures long-term sustainability.
The Wise Farmer Advantage
- At Wise Farmer, we support farmers with:
- Affordable post-harvest solutions (crates, solar dryers, processing tools).
- Training programs on agronomy and crop protection.
- Market access strategies to help farmers sell more profitably.
By adopting simple storage and drying techniques, small tomato farmers in Africa and South America can cut post-harvest losses by half and double their earnings.
⚡ Final Takeaway
Tomato farming doesn’t have to be a losing battle. With better storage, drying, and cooperative marketing, smallholder farmers can turn losses into profits and build sustainable agribusinesses.
