Farmers do not only lose money when the rains fail. They lose it when tomatoes collapse, when grain moulds, when mopane worms are smoked over a fire that also eats the woodland the worms need. Solar dryers sound modest. They are one of the highest-leverage devices in the rural economy.
In Gwanda, solar drying of mopane worms moved from a pilot to a policy conversation because it protected income and trees at the same time. That pattern repeats for chilli, herbs, fruit and seed.
Why dryers stall — and how not to
- A dryer without a market linkage is a warm box. Design the buyer before the steel.
- Hygiene and tray discipline decide whether you are selling food or a lawsuit.
- Women often run the drying. They should own the margin, not only the labour.
GSN will specify and source drying and small processing power as part of an agriculture package. Describe the crop and the volumes.
