<p> Scientists widely accept that modern agriculture is unsustainable, but the best methods for addressing unsustainability are still contested (Constance, Konefal, and Hatanaka 2018). Grassroots sustainable agriculture communities have long participated in the exploration of solutions for agriculture unsustainability, and their momentum continues to grow in the technical age. Practitioners of grassroots sustainable agriculture use many information systems that were not originally built to support the design of agricultural systems.

Today more than 200 million people are suffering from malnutrition in Africa, a major contributing factor to this is that Africa is the continent, by a large margin, that gets least yield per cultivated hectare. The relatively poor yield is not because Africa has no cultivable land but because of the prevailing agricultural practices. Orongo is a village in western Kenya, where large parts of agriculture are threatened by severe soil erosion problems and two-thirds of the inhabitants are totally dependent on agriculture for food and economic security.
