Climate change is no longer just an environmental issue. It has become a burning national security issue. Extreme weather threatens all aspects of Taiwan’s survival. In the face of this all-encompassing challenge, Taiwan must think outside the box and include climate action in national security plans.
Climate change is a national security issue for several reasons. Taiwan is an export-driven economy: The semiconductor industry is key to the global supply chain, and wafer manufacturing requires a stable supply of water and electricity. However, unpredictable rainfall has become the new normal, driving already limited water resources to the brink. A technology park shutting down due to water and electricity shortages would devastate the economy and jeopardize the global supply chain.
The green transformation carries hidden geopolitical risks. Green industries, such as electric vehicles and energy storage, require an increasing amount of lithium, cobalt and other rare earth minerals. However, these strategic resources, often sourced from a handful of countries, could sway the geopolitical battle between the US and China. If Taiwan fails to secure alternative suppliers and establish recycling mechanisms, energy transformation could hinder national security and development.
Climate change brings more than natural disasters; it tests resilience. Taiwan is a small and populous country; even with heavy rainfall, Taiwan has long been troubled by water storage issues. Competition among agricultural, industrial and domestic water is likely to intensify.
Climate disasters drive mass migration. Taiwan has long relied on migrant workers, from countries like Vietnam and the Philippines that are prone to climate disaster. Climate refugees could shock Taiwan’s labor market; they could also strain social welfare, education and healthcare systems, not to mention humanitarian rescue efforts.
Nevertheless, with crises come opportunities. Globally, Taiwan maintains technological advantages in many fields, such as semiconductors, information technology, disaster prevention and energy conservation.
If Taiwan could wield its technological advantages by investing in smart grids, efficient energy storage systems, water management, climate alerts and other key technologies, it would become resilient. Taiwan could become a climate tech hub in the Asia-Pacific region, providing stability and a model for climate governance around the world.
While Taiwan has been excluded from many international organizations, climate diplomacy provides a new opportunity to increase our international presence. By exchanging ideas with other cities, organizations and academic institutions, we can share the nation’s experiences in weather technology, disaster prevention and renewable energy with other partners. These would deepen relations with other Asia-Pacific nations, bolster Taiwan’s diplomatic power, expand its international influence and build mutually beneficial partnerships.
When climate change becomes a national security issue, traditional governance no longer suffices. The government should establish an intergovernmental network, and draft a multifaceted and visionary plan for national security and climate change, which could lay out strategies for water distribution, energy transformation, industrial development, social security and diplomacy.
Climate change is a battle for survival; we have no choice but to brave through. Taiwan must face the risks and treat it as a national security issue. Only then can the nation remain steady amid a turbulent future, ensuring the wellbeing of its residents and its long-term development.

The cancelation this week of President William Lai’s (賴清德) state visit to Eswatini, after the Seychelles, Madagascar and Mauritius revoked overflight permits under Chinese pressure, is one more measure of Taiwan’s shrinking executive diplomatic space. Another channel that deserves attention keeps growing while the first contracts. For several years now, Taipei has been one of Europe’s busiest legislative destinations. Where presidents and foreign ministers cannot land, parliamentarians do — and they do it in rising numbers. The Italian parliament opened the year with its largest bipartisan delegation to Taiwan to date: six Italian deputies and one senator, drawn from six
Recently, Taipei’s streets have been plagued by the bizarre sight of rats running rampant and the city government’s countermeasures have devolved into an anti-intellectual farce. The Taipei Parks and Street Lights Office has attempted to eradicate rats by filling their burrows with polyurethane foam, seeming to believe that rats could not simply dig another path out. Meanwhile, as the nation’s capital slowly deteriorates into a rat hive, the Taipei Department of Environmental Protection has proudly pointed to the increase in the number of poisoned rats reported in February and March as a sign of success. When confronted with public concerns over young
Taiwan and India are important partners, yet this reality is increasingly being overshadowed in current debates. At a time when Taiwan-India relations are at a crossroads, with clear potential for deeper engagement and cooperation, the labor agreement signed in February 2024 has become a source of friction. The proposal to bring in 1,000 migrant workers from India is already facing significant resistance, with a petition calling for its “indefinite suspension” garnering more than 40,000 signatures. What should have been a straightforward and practical step forward has instead become controversial. The agreement had the potential to serve as a milestone in
China has long given assurances that it would not interfere in free access to the global commons. As one Ministry of Defense spokesperson put it in 2024, “the Chinese side always respects the freedom of navigation and overflight entitled to countries under international law.” Although these reassurances have always been disingenuous, China’s recent actions display a blatant disregard for these principles. Countries that care about civilian air safety should take note. In April, President Lai Ching-te (賴清德) canceled a planned trip to Eswatini for the 40th anniversary of King Mswati III’s coronation and the 58th anniversary of bilateral diplomatic
