Vanuatu

In Vanuatu, a collection of 83 tropical, volcanic islands in the South Pacific, sweet potatoes are a primary staple, while regular potatoes are an expensive luxury food. 
The Vanuatu government actively works with farmers to boost potato farming to improve domestic food security.

Sweet potatoes (locally known as Kumala) are an ancient vital dietary staple for the Vanuatu population and a major source of carbohydrates and, especially in orange-fleshed varieties, Vitamin A. Because kumala grows rapidly and survives harsh weather, it is widely utilized by the Vanuatu Department of Agriculture and Rural Development (DARD) as a disaster-recovery crop following cyclones.

Traditionally, common white potatoes have not been a natural part of the Ni-Vanuatu diet. The vast majority of the potatoes consumed by foreign tourists in resorts and restaurants were historically imported.

To stop millions of Vatu from leaving the country and boost the local economy, the Vanuatu government partnered with Australia to launch domestic commercial potato production. The island of Tanna, boasting highly fertile volcanic soil from Mount Yasur, has become the national hub for organic potato cultivation. Local farmers now successfully harvest organic potatoes (such as the Sebago and White Star varieties)

Introduced during the colonial era, potatoes are famously cultivated on Tanna Island, where the highly fertile volcanic soil produces exceptional, completely organic crops. Tanna Island covers a total land area of 550 square kilometers and is the the sixth-largest island in the Vanuatu archipelago.
