About
This data product focuses on tracking land use efficiency and food supply over centuries. It provides the necessary context to understand how humanity can continue to produce the food required to combat hunger and malnutrition while reversing the destruction of nature caused by historical agricultural expansion. By quantifying yield changes, the data enables analysis of the progress already achieved and highlights opportunities for future improvement through technology adoption, policy change, and scientific effort.
Columns
- country: The specific nation or territory for which the yield data was recorded.
- code: The corresponding standardised country code associated with the nation.
- Year: The date of the data observation, spanning a vast historical range.
- Maize yield: The recorded yield output for maize production, measured per unit of land.
Distribution
The dataset is formatted as a CSV file (
yields-of-important-staple-crops new.csv). It contains approximately 13,500 valid records across the four columns listed above. The usability score associated with this data is high (10.00).Usage
- Assessing yield gaps in specific regions to identify areas where new technologies or farming practices could significantly increase output.
- Analysing the long-term historical impact of agricultural changes on land use per person.
- Researching the effectiveness of various binding constraints on productivity, such as irrigation, fertilisers, and seed quality.
- Modelling future food security scenarios based on historical yield improvement rates.
Coverage
Geographic coverage is global, encompassing 241 unique countries or territories. The data’s time range is extensive, beginning as early as the year 1275 and extending through 2023. While the scope covers many centuries, the majority of the data points, nearly 98%, are concentrated from the mid-1980s to the present day, reflecting increased focus on modern agricultural measurements. The primary subject matter is the yield of maize, a major staple crop.
