As climate change intensifies, the integrity of democratic elections across the globe is increasingly at risk. A recent analysis highlights the alarming trend of natural disasters—such as floods, heatwaves, and wildfires—disrupting electoral processes in various countries. The report, published by the International Institute for Democracy and Electoral Assistance, underscores the urgent need for electoral bodies to adapt to the growing threats posed by climate-related events.
Climate Impacts on Elections: A Rising Trend
The comprehensive study documents a staggering 94 elections and referendums across 52 nations affected by climate-related disruptions over the past two decades. In 2024 alone, at least 23 elections in 18 countries—including Brazil, Bosnia and Herzegovina, and Senegal—were impacted by extreme weather events. These disruptions ranged from infrastructure damage to voter displacement, causing significant shifts in electoral processes that could alter political landscapes.
The implications are particularly severe for nations with fragile democratic systems, notably in Africa and Asia, where the compounded stress of climate crises threatens to undermine electoral integrity. This is a stark reminder that democracy is increasingly vulnerable to forces beyond mere political manoeuvring.
Case Studies Illustrating the Crisis
The report provides numerous examples of how climate events have interfered with elections. For instance, Mozambique’s presidential election in 2019 was severely impacted by Cyclone Idai, which flooded homes and infrastructure, displacing voters and affecting overall participation. Similarly, Senegal’s parliamentary elections in November 2024 required firefighters to assist in transporting election observers to polling stations amid significant flooding.
Moreover, heatwaves have emerged as a recurring challenge, with at least ten elections since 2022 disrupted by extreme temperatures. The 2025 general election in the Philippines faced complications when heat caused vote-counting machines to overheat, resulting in the rejection of previously accepted ballots. Such incidents underscore the increasing urgency for electoral bodies to prepare for and respond to climate-related disruptions effectively.
Recommendations for Electoral Resilience
In light of these findings, the report advocates for a collaborative approach involving electoral management bodies, meteorological experts, and disaster relief organisations. This partnership could enhance preparedness and response strategies during elections. For example, electoral officials in Peru have undergone training in disaster risk management to effectively navigate potential disruptions on voting day.
Additionally, some regions are proactively adjusting their electoral calendars. In Canada, the Alberta provincial legislature has shifted its election date from May to October to steer clear of the wildfire season. Such strategic changes could serve as a model for other nations grappling with similar challenges.
Ferran Martínez i Coma, a professor at Griffith University in Australia, emphasises the importance of training and contingency planning. “As natural hazards increase, preparation is key to the integrity and resilience of elections,” he stated. This proactive stance is essential to safeguard democratic processes in the face of escalating climate threats.
Why it Matters
The intersection of climate change and democracy is a pressing global concern that requires immediate attention. As natural disasters become more frequent and severe, the very foundations of democratic governance are at stake. Ensuring the resilience of electoral processes is not merely a logistical challenge; it is a fundamental necessity for upholding democratic values and maintaining public trust in political systems. Without adequate preparations, the consequences could reverberate far beyond individual elections, fundamentally altering the political landscape worldwide.
