A very old technique I learned camping with my parents (admittedly not in Sudan) is the use of a food safe, generally hung from a tree with really good ventilation through it. I have used a modification of this both in Afghanistan where we had no refrigeration and high temperature, where food (fruit, veg, etc) is placed in effectively plastic kitchen racks so the food is only one layer deep on each rack, and keep the differing vegetables / fruits separate. You get good air flow through sides and up through the racks and the foodstuffs stay fresh for some time.
We use a variant of this in rural Cambodia with a lightweight cloth over the racks to keep insects off. Some garlic or alliums (spring onions, onions) basil in the racks keeps a lot of bugs away. In our compound in South Sudan we used the similar idea of a makeshift old fashioned food safe (steel fine mesh box, painted white with closing door and latch) hung under a shady branch of a tree with a good breeze flow through it, and again put the fruit / veg in single layers with air flow from sides and bottom. You can enhance this a little by throwing a wet course cloth (air flow through) over the safe and wet the cloth before putting on the safe rather than pouring water into the cloth and safe. Just an idea may be to have two storage boxes. For example onions deteriorate very quickly if damp whereas leaf crops would likely welcome a damp breeze. Chris
