Abstract
Studying the impact of climate change on grain production, which ensures food security, is one of the most pressing issues today. The most vulnerable sectors in Central Asia are water and agriculture. They are also the main sectors of the economy that ensure stability and food security of the countries of the region. It is worth noting that, according to official data, 70% of the predicted damage from adverse weather and climatic conditions will fall on agriculture. It is known that the yield of agricultural crops is influenced by both internal factors and natural and climatic factors. This article discusses the influence of climatic factors that significantly affect the yield of grain crops. As a result, it was found that the temperature of recent years has a beneficial effect on the growth of spring wheat in the north of the country, and sufficient rainfall also plays an important role for good yields. North Kazakhstan and Akmola regions are well supplied with moisture, while the values of Kostanay region showed the opposite situation. It was found that the yield of spring wheat is negatively affected not only by low, but also by high temperatures. The correlation between yield and air temperature showed a very weak negative correlation (r=-0,3), while a significant positive correlation was found with precipitation (r=0,6).
