Recent research highlights an important link between climate extremes and the risk of armed conflict. As drought conditions worsen, especially in vulnerable regions of Africa and Southeast Asia, the chances of conflict increase significantly.
This study, published in the Proceedings of the National Academy of Sciences, analyzed climate and conflict data from 1950 to 2023. Researchers found a clear connection between conflicts and climate impacts driven by two well-known patterns: El Niño and the Indian Ocean Dipole. These patterns, which affect rainfall and drought across the globe, become even more intense due to human-caused climate change.
Historically, climate extremes have influenced societies for centuries, but separating climate effects from other factors—like demographics and social pressures—has been difficult. This latest study aims to clarify these relationships by treating climate shifts as a lens through which to examine decades of conflict data.
The findings revealed three main insights: First, conflict risks tend to rise during El Niño years compared to La Niña years. Second, not all droughts lead to conflict; violence often occurs only after drought conditions hit a critical point. This threshold varies between larger regions and smaller local areas. Third, major conflict risks are tied to droughts triggered by El Niño, particularly in Central America and southern Africa.
As Justin Mankin, a co-author and climate expert at Dartmouth College, explained, “Dry conditions create more stress. Throughout history, prolonged droughts have led to societal strain.” Such stresses can lead to economic hardship, making it easier for armed groups to recruit in unstable areas.
A crucial takeaway is that we are not well-prepared for the climate we currently face, let alone the changes coming from global warming. Mankin notes that the real drivers of conflict lie outside climate change. A 2019 study in Nature found that socioeconomic development, government effectiveness, and inequality are stronger predictors of conflict than climate factors. Climate variability can, however, act as a catalyst, triggering conflict where vulnerabilities already exist.
Experts warn not to frame climate impacts solely as security threats. Doing so can divert attention from other significant issues like poor governance and corruption, which often dictate whether environmental stress leads to violence. Mankin believes that understanding climate patterns like El Niño can help develop better forecasts, enabling humanitarian efforts to respond proactively to impending crises.
Sylvia Dee, another co-author and climate researcher at Rice University, agrees that collaborative efforts across various fields are vital. “Climate change has been linked to conflict for years, but understanding these connections requires input from multiple disciplines,” she said. “When urgency arises, humanity can tackle critical problems.”
The study also underscores the importance of local perspectives. Engaging with communities affected by climate change can provide deeper insights and solutions. With ongoing changes in our climate, embracing a multifaceted approach that includes all relevant factors is crucial for addressing both the social and environmental challenges ahead.
