World map of the number of publications in sustainability science between 2018 and 2021.
The number of articles is represented by circles of different sizes. The map was reprinted from https://www.naturalearthdata.com under a public domain license.
Fig 2.
Polar diagram of co-authorship among countries in Nature Sustainability between 2018 and 2021.
Lines indicate collaboration between countries, with line thickness indicating the intensity of the relationship (the greater the thickness, the greater the number of articles co-authored, and vice versa). Circle size is proportional to the number of articles and circle colours correspond to the country’s income category. Line colours show the lowest income category between co-authoring countries. Lines for only one co-authorship are not shown for the purpose of clarity.
Fig 3.
Difference in publication rates between Nature and Nature Sustainability.
The colour scale indicates whether authors from the country publish more in Nature (blue) or Nature Sustainability (red) after accounting for total publication volume. Circle sizes reflect the country’s proportion of publication combined across both journals. When several authors from the same country co-authored the same publication, the country has been considered only once. The calculation of the difference in publication score is given in the Methods.
