Which crops and domesticated animals did Oceanian societies use before European contact?

Before European contact, Oceanian societies relied on a variety of cultivated crops and domesticated animals, primarily of Southeast Asian origin.1

Crops

Oceanian agriculture focused on the cultivation of tubers and tree fruits. The primary staples included:1
* Root crops: Yams and taro were the most significant staples, with production methods often shaping local social structures.2
* Other plants: Societies also cultivated plantains, sago, pandanus, leafy greens, and sugarcane.2
* Sweet potato: A notable exception to the Southeast Asian origin of these crops is the sweet potato, which originated in South America and spread throughout most of Polynesia in pre-European times.12

Domesticated Animals

There were three primary groups of domesticated animals maintained by these societies:
* Pigs
* Dogs
* Chickens1

These resources were often supplemented by fishing, the hunting of birds and marsupials, and the gathering of wild foods such as nuts and fruits.2
