Alexander et al. – Human appropriation of land for food: the role of diet

This data is based on the published work of Alexander et al. (2016). Human appropriation of land for food: The role of diet. Full reference below.

The authors calculate the HALF (Human appropriation of land for food) index, which measures the percentage of total land area we would need for the global population to consume the average diet of any given country. This is based on population and dietary figures from FAO 2011 data.

OWID have re-calculated these figures as the percentage of habitable land area (rather than total land area). This corrects for land which is either barren or glacial land and could not be used for agriculture or other land uses. To correct for this factor, we have assumed that 71% of total land area as habitable (with 10% glaciers and 19% barren land); figures based on WWF (2016). Living Planet Report 2016.

A HALF Index value of 100% means that 100% of global habitable land area would be needed as agricultural land to provide for global diets. Values >100% are not physically possible within global land constraints.

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.
