Which crops are central to subsistence agriculture in rural New Caledonia?

In rural New Caledonia, subsistence agriculture remains vital for many Melanesian families. The primary staple crop central to this practice is the yam.13

Additionally, taro holds significant importance in the region, a fact historically evidenced by the presence of traditional terraced and irrigated fields used to maximize its production. While subsistence farmers have historically sought to diversify their crops—including efforts to produce coffee and copra to enter the cash economy—these remain secondary to the traditional root crops that form the foundation of the local diet.23
