Tonga faces significant challenges as climate change exacerbates multidimensional poverty and disproportionately affects vulnerable populations, including those with disabilities. According to the UNICEF Pacific National Analysis of Overlapping Deprivations (N-MODA), multidimensional poverty—which tracks deficits in income, education, and basic infrastructure—is notably higher in outer island groups compared to the urban hub of Tongatapu.
The Impact of Climate Change on Economic Stability
The Tongan economy relies heavily on agriculture and fishing, sectors that are increasingly precarious due to environmental shifts. These events do more than destroy infrastructure; they deplete the natural resources that sustain rural households. When storms strike, the loss of agricultural output creates a cycle of economic instability, making it difficult for families to recover and trapping them in a state of multidimensional poverty.
Poverty Disparities Across Island Groups
Poverty in Tonga is not distributed equally. While approximately 75% of the population resides on the main island of Tongatapu, residents in outer island groups—specifically Vava’u, Ha’apai, ‘Eua, and the Ongo Niua—experience higher rates of deprivation. Data indicates a significant gap in living standards:
- Adult Poverty: A 2018 analysis revealed a 25% difference in multidimensional poverty levels between Tongatapu and the outer islands.
- Child Poverty: Children in rural areas are particularly vulnerable, with nearly one-quarter of all Tongan children experiencing multidimensional poverty.
- Regional Variations: ‘Eua records the highest rate of child poverty, followed by Ha’apai and Ongo Niua, which also face high levels of deprivation.
These children often lack consistent access to adequate nutrition, clean water, healthcare, and secure housing, according to the UNICEF N-MODA report.
Disability and Environmental Vulnerability
Disability in Tonga is closely linked to socioeconomic status. This discrepancy is attributed to the exclusion of "mild" impairments in local surveys and social stigma that may discourage self-reporting.
For individuals with disabilities, climate-related disasters present acute risks. Emergency evacuation protocols often fail to account for the needs of those with mobility or sensory impairments. Many individuals report that they must abandon essential assistive devices during evacuations, leaving them without necessary support in shelters that may not be fully accessible.
Ongoing Mitigation and Support Efforts
Governmental and non-governmental organizations are working to address these systemic inequalities. The Tongan government, supported by UNICEF Pacific and the Social Policy Research Institute, utilizes the N-MODA framework to align national policies with the United Nations Sustainable Development Goals (SDGs).
Advocacy groups are also playing a critical role in policy development. Organizations such as the Pacific Disability Forum, the Tonga National Visual Impairment Association (TNVIA), and the Tongan National Disability Council (TNDC) work to ensure that the voices of people with disabilities are included in disaster preparedness and poverty reduction planning. Additionally, international aid organizations like CARE International have been active in Tonga since 2019, implementing programs designed to help rural communities build long-term resilience against natural disasters. These initiatives focus on both immediate disaster response and sustainable interventions to improve the quality of life for the most marginalized populations.
