Explain the functions of a grocery warehouse in Zimbabwe.

A granary in Zimbabwe traditionally served as a storage facility for grains like maize, sorghum, and millet. Its primary functions included:

1. Preservation of Food Supply: It ensured a reserve of food for the community, especially during dry seasons or periods of crop failure, preventing famine.
2. Protection from Pests and Weather: Granaries were designed to protect stored grains from rodents, insects, moisture, and harsh weather conditions, thus minimizing spoilage and loss.
3. Community Resource Management: They acted as a communal storehouse, allowing for equitable distribution of food resources among villagers and facilitating trade or bartering.
4. Seed Bank: Granaries also preserved seeds for the next planting season, ensuring the continuity of agricultural production.
