Global climate change has a significant impact on food sustainability throughout the world. Temperature fluctuations, changing rainfall patterns, and an increase in extreme weather events are shaking up existing agricultural systems. These impacts affect the quality, quantity and safety of food that is urgently needed by a growing population. One of the main impacts is a decrease in crop yields. Some rice, corn and soybean crops, which are staple foods, become vulnerable to high temperatures. Research shows that every 1 degree Celsius increase in temperature can reduce rice yields by up to 10%. This is related to thermal stress which causes plants to not be able to carry out photosynthesis optimally. Changes in rainfall patterns also have a direct impact on the availability of water for crop irrigation. Areas that previously had a climate that supported agriculture are now experiencing prolonged drought. On the other hand, there are areas that experience extreme flooding, destroying agricultural land and destroying crops. This combination causes uncertainty in food production, which in turn disrupts global food supply chains. The effects of climate change are also visible on plant pollination. Many plants depend on insects for pollination. With increasing temperatures and changing habitats, many insect species, such as bees, are experiencing population declines. Without effective pollination, fruit and vegetable production is hampered, impacting food diversity and availability. Farmers’ adaptation to climate change is crucial. By adopting more resilient agricultural practices, such as using climate-resistant varieties and soil conservation techniques, farmers can reduce negative impacts. Climate-smart agricultural techniques, such as efficient water management and crop rotation, provide opportunities to increase food security even amidst uncertain conditions. Climate change is also contributing to an increase in plant pests and diseases. Warmer temperatures speed up the life cycle of some pests, allowing them to develop more quickly and attack plants in greater numbers. This poses additional challenges for farmers who must manage pests in an environmentally friendly way, without damaging the ecosystem. More exposed communities include small farmers and those who depend on subsistence farming. Reduced harvest yields and increased production costs risk triggering economic instability and food insecurity. In this context, it is important to increase the involvement of governments and international organizations in creating policies that support sustainable agriculture and environmental protection. Preparedness to deal with climate change is critical to achieving global food sustainability goals. Investments in agricultural technology, sustainable agricultural research, and education for farmers can increase adaptive capacity. With an integrated approach, it can be hoped that the negative impacts of climate change can be reduced, while ensuring better access to food for everyone.
