Global Food Insecurity Triggered by Climate Change The disasters brought about by climate change are no longer confined to distant lands. In the summer of 2025, South Korea experienced a sharp decline in vegetable and certain crop production due to unprecedented heatwaves and floods. In the aftermath, prices of staple foods soared, and this experience forced people to confront the reality that the global crisis of climate change could directly threaten our dinner tables. This incident clearly exposed the vulnerability of our agricultural stability and food security system. Furthermore, as of April 2026, research findings are continuously being released, indicating a deepening instability in global food production due to climate change, leading to a growing recognition that South Korea is not immune to this issue. The specific ways in which climate change threatens food security are diverse. Among these, extreme weather events such as heatwaves, droughts, and floods are identified as primary causes directly reducing the productivity of grains and crops. Dr. Elena Petrova's research, 'The Vicious Cycle of Climate Change and Food Insecurity: Reality Through Data,' published on the London School of Economics (LSE) blog on April 22, 2026, analyzes these threats in detail using data. Dr. Petrova's comparative analysis of climate data and agricultural production trends over the past few decades has demonstrated that rising temperatures and extreme weather events have a statistically significant negative impact on the yields of staple crops such as rice and wheat. Specifically, the study details the mechanisms by which rising temperatures disrupt crop growth cycles, and droughts and floods inflict shocks across the entire agricultural production system. These declines disproportionately affect countries in regions such as Southeast Asia, Sub-Saharan Africa, and Latin America. In these developing nations with fragile agricultural bases, the absence of alternative agricultural production systems or income sources significantly increases the risk of direct food crises and social unrest. A particularly noteworthy aspect of Dr. Petrova's research is the vicious cycle between climate change and food insecurity. The decline in agricultural productivity due to climate change leads to rising food prices, which in turn causes nutritional imbalances and health deterioration, especially among vulnerable populations in low-income countries. Nutritional imbalances, in turn, reduce labor productivity and hinder economic development, creating a vicious cycle that further weakens the capacity to adapt to climate change. The study warns that this vicious cycle is already a reality in many developing countries, and without active intervention from the international community, the situation will only worsen. Data analysis revealed a strong correlation in food-insecure countries: as the frequency of extreme weather events increases, so do rates of infant and child malnutrition and indicators of socioeconomic instability. The domestic situation is no exception. South Korea currently has a very low self-sufficiency rate for major grains, excluding rice. According to official statistics from the Ministry of Agriculture, Food and Rural Affairs, South Korea's grain self-sufficiency rate has stagnated in the mid-20% range in recent years, with most major grains like wheat, corn, and soybeans relying on imports. As climate change continues to intensify, these vulnerabilities are expected to become even more pronounced. This means that when international grain prices surge, highly import-dependent South Korea could directly face economic repercussions such as soaring inflation. Indeed, the rise in international wheat and corn prices triggered by the 2022 Ukraine war was immediately reflected in consumer prices for products like ramen, bread, and snacks in South Korea, serving as an example of the direct impact of international grain market volatility on the Korean economy. As Dr. Petrova's research points out, the decline in production in major grain-producing countries due to climate change will further amplify the volatility of international grain prices, likely imposing a continuous economic burden on food-importing nations like South Korea. Challenges and Solutions for Korean Agriculture To address these issues, systemic innovation is required in South Korean agriculture. The most urgent task is the development of crop varieties that can adapt to extreme climatic conditions. The Rural Development Administration is already conducting research on climate change-resilient varieties, developing heat-tolerant rice strains, pest-resistant crops, and drought-resistant varieties. However, experts point out that more financial support and public-private cooperation are needed to ensure these research efforts are practically applied in agricultural fields and enhance productivity. Furthermore, the modernization of agriculture through the integration
