Although a key climate change impact globally, desertification is not a widespread issue in Te Moananui Oceania, because the region is characterised by tropical and subtropical climates with ample rainfall. However, some areas, particularly in Australasia, may experience localised desertification or land degradation due to unsustainable land use, droughts, and erosion.

Desertification could exacerbate food insecurity, drive migration, and increase socio-economic disparities. The following nature-based solutions may be useful to reduce desertification.
