Due to sea-level rise, small states like Vanuatu will disappear or become inhospitable. Communities will have to become diasporic and governments in Vanuatu, Palau, and Dominica have placed significant importance on digital identity.

Diminished economic viability of existing livelihoods in low-lying islands, requires new avenues for government funding. Caribbean and Pacific small states have partnered with for-profit entities to implement Web3-based digital identity solutions, which not necessarily are fit for purpose.

Thus, digital identity and a critical understanding of it as a tool of governments and communities contributions to the development of a sound adaption strategy of small states and jurisdictions.

While it cannot mitigate climate change, digital identity is an integral part of SDG-based climate change adaptation in Small Island Development States (SIDS).
