Global map of peak years
Map of countries peak-rate year and percentage increase of production at peak rate year
What is displayed?
Either for all crops combined or for a selected crop, each country is potted in a different color (yellow: there is a peak-year, orange: no peak year, gray: no sufficient data, mostly because crop not planted). Additionally, colored circles illustrate the year, when production has had a peak (color) as well as the rate of production increase for that peak year (size of circle)
What can be changed interactively?
On default the peak years of all crop combined based on their caloric value are shown. If in the panel to the left a certain crop is selected, the map changes accordingly.
When selecting a certain crop, also the info-box to the left is updated an the peak-rate year of that specific crop is updated.
Forest plot of peak years
Forest plot showing the estimated peak year and its uncertainty for each crop that is planted in the regions of interest (global or selected country)
What is displayed?
For each crop the median peak rate year of production is displayed, if identified. Uncertainty bars represent 2.5th and 97.5th percentiles derived from 5,000 bootstrap estimates (see Data & Methods). Point size illustrate the relative increase of production in percent in that peak rate year. Note, due to bootstraping the resulting distribution of peak-rate years can be skewed and the median peak rate year might not necessarily be centered in the confidence interval.
What can be changed interactively?
On default the peak years of crops of all countries (global) is shown. If a country is selected, the figure shows the crops that (a) are produced in the county and (b) that show a peak rate year.
Note, when selecting a country also the histograms in the bottom row changes and shows the total area harvested for all crops in that country (bottom left) as well as the total calories produced for each crop in that specific country (bottom right). Also the info-box to the left is updated and the peak-rate year of crop production in that country is displayd, summarized for all crops combined based on the caloric value.
