Climate change is one of the most pressing issues facing the world today, and its impact on global food security cannot be ignored. With the increase in the earth’s average temperature, unpredictable weather patterns, and the higher frequency and intensity of natural disasters, the agricultural sector is also experiencing major challenges. Crops, which are highly dependent on climate, are now threatened by drought, floods and increasing pest attacks. One of the biggest impacts of climate change is the shift in growing seasons. Changes in temperature can cause the soil to warm up more quickly or slowly than usual, leading to suboptimal planting and harvest. For example, rice farmers in Southeast Asia are now experiencing difficulties when their favorite rice varieties fail to produce optimally due to changes in rainfall patterns. Delays in rainfall increase the risk of crop failure, resulting in significant reductions in production and the threat of famine. Not only that, higher temperatures also increase the reduction in soil quality. The faster process of dehydration and evaporation due to rising temperatures can cause land degradation and loss of essential soil nutrients. Without proper intervention, this threatens agricultural supplies globally. In this case, nutritional and food deficiencies are becoming increasingly severe, especially in developing countries where dependence on subsistence agriculture is very high. Climate change also affects the availability of clean water. As more and more areas experience prolonged drought, access to water sources for irrigation is becoming very limited. In areas that are usually sufficient for agriculture, there is now a significant reduction in water availability. This results in farmers having to look for alternative water sources, which are generally more expensive and energy-intensive. In a global context, the impact of climate change on food security is also influenced by international trade. Countries that rely on imports to meet food needs can be faced with the problem of supply chains being disrupted due to natural disasters. This causes an increase in food prices and a more widespread crisis, potentially triggering social unrest. Technology can be an important pillar in facing this crisis. Sustainable agriculture, use of plant varieties that are resistant to extreme conditions, and soil conservation practices can be profitable solutions. Additionally, the development of innovative irrigation systems and better weather monitoring will help farmers plan and adapt to changing weather conditions. Through global cooperation, inclusion of environmentally friendly policies, and investment in agricultural research, we can strengthen food security. Ensuring that the world’s population has access to sufficient, nutritious and safe food is a challenge that must be faced together. As a global community, we must be more proactive in mitigation and adaptation strategies so that the impacts of climate change do not further exacerbate the existing food crisis.
