Cereal yield data measures kilograms produced per hectare of harvested land for grains including wheat, rice, maize, barley, oats, rye, millet, sorghum, buckwheat, and mixed grains. The World Development Indicators from the World Bank compile this data, which is allocated to the calendar year of harvest by the Food and Agriculture Organization (FAO). Production figures are for dry grain only, excluding crops harvested for hay, green feed, or grazing.
Use Cases
- Analyze temporal trends in cereal_yield per country to assess agricultural productivity changes.
- Model the relationship between yield and climatic or economic indicators using country and year fields.
- Compare production efficiency across different cereal types (wheat, rice, maize, etc.) within the aggregated data.
- Forecast national food supply by projecting yield metrics for key grains over future years.
Strengths
- Data covers major global cereal crops including wheat, rice, and maize.
- Methodology clearly defines inclusion (dry grain) and exclusion (green feed, grazing) criteria.
- Production is allocated to specific harvest years by the FAO for temporal consistency.
Limitations
- Specific row count, time range, and geographic coverage are unknown from the input.
- Data is aggregated for cereal groups; individual crop breakdowns may not be available.
- The description indicates most late-year harvests are consumed the following year, which may create a lag between production and utilization data.
