Global warming is an urgent issue that has a significant impact on global food security. The increase in Earth’s average temperature, triggered by greenhouse gas emissions, is triggering various climate changes that threaten the agricultural sector. One of the most obvious impacts is changes in rainfall patterns. In many areas, reduced rainfall could lead to severe drought, reducing crop yields and increasing stress on water resources. Moreover, previously fertile areas suddenly became unable to support agriculture, resulting in a shortage of food supplies. In addition, the increasing frequency and intensity of natural disasters such as floods, storms and heat waves add to the challenges for farmers. Food production is sometimes disrupted by unexpected disasters, damaging infrastructure, reducing crop yields, and increasing food prices. Ecosystem services derived from biodiversity are also threatened, potentially reducing soil fertility and increasing susceptibility to pests and plant diseases. Climate change is also affecting the migration patterns of pests and diseases, forcing farmers to adapt by using more chemicals, which can be harmful to human health and the environment. This impact not only impacts agricultural yields, but also impacts the sustainability of the food system, by causing price increases and supply uncertainty. Developing countries, which often depend on agriculture as a primary source of income, are particularly vulnerable to the impacts of global warming. They lack the resources to adapt to climate change, and thus face increasing food shortages and economic instability. This has the potential to trigger mass migration and conflict due to the fight for increasingly limited resources. Apart from that, the impact of global warming also affects the nutritional quality of food. Decreased quality and quantity of agricultural products can result in malnutrition, especially among vulnerable populations, such as children and pregnant women. Non-nutritious food can affect growth and development, and increase the risk of disease. Transforming the food system towards a more sustainable one is urgently needed to overcome this impact. Innovations in agricultural technology, water conservation practices, and the use of climate-resistant crop varieties are crucial. Education of farmers about adaptation and mitigation strategies is also an important part of the solution, increasing the resilience of the global food system. Every individual and collective action to reduce carbon emissions will contribute to addressing global warming and, in turn, help secure future food supplies. Mobilizing countries and international organizations to create policies that support sustainable agriculture is an important step towards a better future.
