Simple improvements to traditional granaries may reduce the loss of grains to pests and diseases without requiring financial outlay. A workshop was held in Mundri, Sudan to look at grain storage. Relevant teaching was first given about the main enemies of stored grain – mould, insects, rats and mice and the four main environmental factors affecting their multiplication – heat, moisture, air and dirt. New ideas and designs were then introduced and discussed. Finally, however, the participants made their own decisions about an improved design for them.
1 The new design has fewer legs – only 6 or 4.
2 The platform was raised to over 1m from the
ground to prevent rats and mice jumping up.
3 Supports for the basket rise from the raised
platform – not the ground.
4 Rat guards (made from old tin cans) are put
on the legs at knee height or above.
5 The inside of the basket is coated smoothly
with anthill mud and slime from a vine
(Cissus integrifolia). Traditionally, buffalo
dung was used but this is now in short
supply and very difficult to get.
6 The roof is attached to the basket with poles
reaching the platform rather than the ground.
Combining traditional skills and materials with
the opportunity to discuss new ideas, resulted
in a design which proved both practical and efficient in reducing the amount of grain
destroyed by rodents and insects.
