Part 7

Explore all bonus resources in Civilization IV, including their food, production, and strategic value. Learn where to find them and how to best utilize them for your empire's growth.

This section details the various bonus resources available in Civilization IV, explaining their yields and strategic importance.

Bananas provide +2 Food and are typically found in warmer, tropical regions like South America. They offer the least food yield among food bonuses, comparable to Deer.

Corn provides +3 Food. It's commonly found on plains or grasslands, often near rivers, significantly boosting food production. It's one of the most useful food resources.

Cotton provides +2 Cotton and can be used to produce cloth or exported to other colonies for manufacturing.

Crab provides +3 Food and is found in coastal waters. Port cities with access to Crab can achieve high populations, as sea resources generally yield more food than land tiles.

Deer provide +2 Food. While they can also provide Fur, a tile can only yield one resource at a time. This resource is often found on Tundra tiles.

Fish provides +4 Food, the highest yield of any food bonus. Settling near Fish tiles is highly advantageous, especially with early access to Docks.

Fur provides +2 Fur and is typically found near the North Pole, often on Tundra tiles (e.g., Canada on the Western Hemisphere map). Beavers are a common source.

Iron provides +2 Ore and is found in hilly or desert tiles. It is crucial for producing advanced military units like muskets and guns.

Silver provides +2 Silver and can only be mined from mountain tiles. It's essential to settle on or adjacent to mountains to exploit this resource.

Sugar provides +2 Sugar and is often found in the Caribbean. It's primarily used for Rum production and may require docks for survival on small islands.

Tobacco provides +2 Tobacco and is usually found inland. It's valuable for producing cigars and requires transport via wagon train to port cities for export.

Coast tiles provide +1 Food and grant defending units +10% Strength. Settlements cannot be built on Coast tiles.

Desert tiles provide +2 Ore but require +25% more time to build improvements. They often lack sufficient food sources, making them better suited for ore extraction and export.

Grassland tiles provide +3 Food and can also yield +3 Tobacco, offering a choice in production.
