Tonga is stepping up its efforts to tackle climate change. Recently, the government, through the Department of Climate Change, hosted a workshop to review findings about climate-related loss and damage in the country.
Climate change is hitting Tonga hard. It’s causing significant damage to infrastructure, water systems, agriculture, fisheries, and local livelihoods. Beyond physical losses, there’s also a toll on cultural heritage, traditional knowledge, and ecosystems. A recent study by the World Bank estimates that climate change could cost Pacific Island countries like Tonga up to 12% of their GDP by 2050 if no action is taken.
This workshop is a key part of creating Tonga’s first National Evidence Base Report on Climate Change-Induced Loss and Damage. The report pulls together insights and data from extensive discussions, including voices from communities in the outer islands of Vavaʻu, Haʻapai, and ʻEua.
Organized in collaboration with the Secretariat of the Pacific Regional Environment Programme (SPREP) and funded by New Zealand, the workshop brought together government officials, NGOs, the private sector, and development partners. Their goal? To affirm and refine the findings from the evidence base.
Experts from various sectors shared valuable knowledge, highlighted data gaps, and ensured the report offered a well-rounded understanding of the climate impacts across Tonga.
Mr. Richard Reinen-Hamil from Tonkin + Taylor underscored the importance of this effort. A validated National Loss and Damage Evidence Base will guide policy making and planning. It will also help Tonga access crucial climate finance, paving the way for resilient development.
In an age where climate discussions are dominated by urgent action, this initiative places Tonga on a stronger footing. As global weather patterns become more extreme, the importance of local expertise in shaping protective measures cannot be overstated. Engaging communities directly ensures that the strategies crafted will fit their needs and realities.
In summary, Tonga’s collaborative approach to addressing climate change serves as an important model for other nations facing similar challenges. By validating their findings and uniting various sectors, they’re not just gathering data—they’re building a future that can withstand the storms ahead.
