Dynamics of global harvest and production of cereals: Exploring trends for 30-year period

Cereals are the world's largest crops and the key source of staple food for millions of people globally. In this study, we analyse the trends in the production and growth of the most important and widely grown types of cereals cultivated as grain globally: 1) maize (corn), 2) wheat, 3) rice; 4) barley; 5) sorghum; 6) oats; 7) millet; 8) rye. The dataset on the produced cereals was collected from the Food and Agriculture Organization (FAO). Methods include the analysis of geospatial and economic data on the agricultural production of cereals for the period 1993-2023 and relevant literature review. The results revealed major trends in the agriculture production harvest of cereals at the global scale: the increase in production and yield quantities was noted for 4 crop types: maize, rice, wheat, millet. In contrast, barley, sorghum, oats and rye shown decrease in harvest in recent 30 years. The study contributes to the analysis of food security and crop availability for sustainable agricultural development.
