Cereals include wheat, rice, maize, barley, oats, rye, millet, sorghum, buckwheat, and mixed grains. The monthly brief is supplemented by a detailed assessment of cereal production as well as supply and demand conditions by country/region in crop prospects and food situation, published three times per year. This paper reviews maize production, consumption, and international trade to examine the changing trends in global supply and demand conditions over the past quarter century and the implications for research and development (r&d), particularly in the global south. Climate change will affect agricultural production worldwide Average global crop yields for maize, or corn, may see a decrease of 24% by late century, if current climate change trends continue Wheat, in contrast, may see an uptick in crop yields by about 17%.
We use detailed crop statistics time series for ~13,500 political units to examine how recent climate variability led to variations in maize, rice, wheat and soybean crop yields worldwide. Explore data on cereal yield per hectare, including various grains, provided by the world bank. More frequent hot weather and droughts have dealt a significant blow to crop yields, especially for key grains like wheat, barley, and maize, according to a stanford study published this week in proceedings of the national academy of sciences. Despite expected competition from other crops, steady gains in area and yields are forecast to underpin global outturns in the next five years, with fresh records projected from 2020/21 onwards. Global production of primary crop commodities reached 9.6 billion tonnes in 2022, increasing by 56 percent since 2000 and just 0.7 percent since 2021 The global production of cereals decreased by 12 million tonnes, or 0.4 percent between 2021 and 2022, driven by a drop in maize production.
