All resources also give a fixed bonus of 1 food, 1 hammer or 1 commerce to the base value of the terrain, in addition to the improvement bonus. This bonus is given even if you do not improve them, or build a different improvement than the standard one on them. For standard improvements the terrain types it can be built upon are listed below the name. Resource improvements can always be built on their respective resources, regardless of terrain. For them, the required technology is listed below the name instead. Farms and Mines are both standard improvements and resource improvements. The latter function overrules the former. So if you build them on one of their associated resources their effect is given in the second table, not the first.
