Holistic concept for better food supply

Short description

In this project, chicken manure is to be used as fertilizer to increase the harvest. The local population is also trained in the construction of refrigerators without electricity and the production of mulch.

The problem we aim to solve

The project looks at the phenomenon of unbalanced nutrition with cassava, beans, peanuts, tomatoes or sweet potatoes. Milk and meat are consumed too rarely when there is no way to preserve them. The self-built refrigerator is supposed to help. With more income, other, more expensive seeds (food) containing other vitamins can then also be purchased, for example pomegranate or potatoes. Nutrient-rich herbs such as oregano or thyme could also be cultivated.

Our solution

Chicken farms are an important source of income in Uganda. More and more people are using them. Experience shows that a lot of chicken excrement is produced, which is only collected, but not used elsewhere. If this is used as fertilizer, the yields of the already good soil can be increased. Mulch from sugar cane, for example, also serves as protection against rodents and keeps moisture in the soil. The surplus of the harvested food can therefore be marketed. Additional teaching units with the local farmers or with the children at school can spread the knowledge about the simple construction of a non-electric refrigerator. The food is stored in a more hygienic and cooler place, thanks to the thoughtful protection against rodents and insects both at the cabinet feet and in the water container. This means that the meat of a slaughtered cow or milk and dairy products can be kept longer. The diet can thus be varied. Through holes in the ground, in which laundry drums are buried, food can also be stored cooler in closed containers such as jam jars. The protection against rodents and erosion are also important. By planting peanuts around the hole in the ground, the hole in the ground can be prevented from collapsing. They support the ground. With this concept, farmers are just as independent of the large companies and their seeds or fertilizers.

The innovativeness of our approach

The idea of working with simple and natural means is particularly innovative. Existing products are used, which are only used in a different way. In inland Uganda it makes sense to use existing products. The training sessions should also be designed in such a way that the farmers get the feeling that they have come up with the ideas mentioned above. They are more likely to put it into practice because they specifically recognize the meaning and advantages behind it.

Technologies and Methods

As already mentioned, well-known and regional products are used. Only the methods of use have been modified. Power-free, simple methods without technology are used.

Potential Partners

Contact with schools and existing local development workers would be helpful. The same applies to Ugandan scrap dealers who, for example, have old laundry drums. At best, partners must also be found on site who sell rustproof fly screens (for the refrigerator). Contact with regional seed producers and distributors also plays an important role. The local companies will therefore be involved and needed in any case.
