Banaba (Ocean Island)

Banaba rises dramatically from the surrounding ocean as a raised coral island, quite unlike the low-lying atolls that characterise most of Kiribati. The island stands perhaps 80 metres above sea level at its highest point, its phosphate-capped cliffs and rocky interior visible from many kilometres away and giving the island a silhouette unlike any other place in the Pacific. The approach by boat from the south reveals the characteristic orange-brown colour of the phosphate deposits that coat much of the island's surface, the result of millions of years of bird guano accumulation that made Banaba one of the most phosphate-rich islands in the world. The scale of the mining damage is immediately apparent from the boat: the interior of the island is pockmarked with enormous excavation pits, and the former mining settlement of Umong has been largely abandoned, its buildings and infrastructure gradually consumed by the advancing excavation edges.

The phosphate deposits that made Banaba so valuable were the cause of its destruction as a habitable place. The British Phosphate Commission extracted the mineral from 1900 onwards, shipping millions of tonnes to Australia and New Zealand as fertiliser for their agricultural economies. When the reserves were effectively exhausted by the 1970s and 1980s, the island had been so comprehensively stripped that the soil could no longer support agriculture or reliable freshwater. The population of around 4,000 was relocated to the Solomon Islands (specifically to the island of Rabi) in 1945 and again in the 1970s, and today the remaining residents of Banaba number only a few hundred, living primarily in the village of Anterea on the island's more sheltered eastern coast. The story of Banaba has become emblematic of the darker side of colonial resource extraction in the Pacific, and the island's case was taken up by the United Nations during decolonisation discussions in the 1970s and 1980s.

The UNESCO inscription of Banaba as a cultural landscape in 2014 reflected the island's status as a unique case study in the relationship between colonial resource extraction and indigenous displacement. The landscape itself is the evidence: the excavation pits, the abandoned machinery, the eroded phosphate surfaces, the collapsed buildings. The remaining inhabitants maintain a fierce attachment to Banaba despite the destruction, returning annually for cultural visits and maintaining legal claims over the island against the governments of Australia and New Zealand, which benefited substantially from the phosphate extraction. The phosphate deposits remaining in the deep excavation are now an aspect of the landscape itself, their orange-white mineral crust creating a visual texture unlike any other island environment in the Pacific.

The surrounding ocean around Banaba is deep blue and rich in marine life, the island's isolated position in the eastern Gilbert Islands making it a productive spot for pelagic fish species. Snorkelling around the island's reef margin reveals good coral cover in areas not affected by sediment run-off from the mining operations.
