Harvesting Today Means Selling Today
- Lack of electricity in most of the northern rural communities, for without electricity
there can be no refrigeration. - Even in towns and cities the power supply is erratic.
- Most of the urban poor cannot even afford refrigerators.
- Mostly agriculture-based population, the majority of them live in abject poverty.
- Polygamy is a dominant feature of the family structure, and women, living in purdah, are confined to their homes.
- Women are seriously disadvantaged in terms of health care, education and employment opportunities.
- Young girls are particularly enslaved because they are forced to go out each day in order to sell rapidly food that would otherwise perish, in order to add to the meager family income.

Mohammed Bah Abba Re-Invention With His Pot-In-Pot Desert Refrigerator
Diagram Of The Pot-In-Pot Desert Refrigerator
The pot-in-pot cooling system, a kind of “desert refrigerator”, helps subsistence farmers by reducing food spoilage and waste and thus increasing their income and limiting the health hazards of decaying foods
The pot-in-pot consists of two earthenware pots of different diameters, one placed inside the other. The space between the two pots is filled with wet sand that is kept constantly moist, thereby keeping both pots damp. Fruit, vegetables and other items such as soft drinks are put in the smaller inner pot, which is covered with a damp cloth.
Abba’s first trials of the pot-in-pot proved successful.
- eggplants, for example, stayed fresh for 27 days instead of 3
- tomatoes and peppers lasted for 3 weeks or more
- african spinach usually spoils after a day, remained edible after 12 days in the pot-in-pot[/list]
