Strategy
The Granary increases the 
Food production of a city, speeding up the city's growth, especially if it has one of the above-mentioned resources nearby (which need not be improved with a Farm). It's always useful when you want to create a large city, and for speeding up growth of smaller ones. It's also incredibly useful to help cities with poor access to fertile land.
Civilopedia entry
A granary is a building constructed to store grain for human or herd animal consumption (or both). The earliest granaries yet discovered were found in a pre-pottery Neolithic settlement in the Jordan Valley of the Middle East, and date back to approximately 9500 BC. These first granaries measured about 10-foot by 10-foot square. They featured raised floors which allowed air to circulate more freely and provided some protection for the grain from mice and other menaces.
