In the wider sense, this does not only refer to the resources that humans consume, but also nature’s capability to absorb and regenerate the waste that we produce. With a still growing population as well as an increasing use of natural resources, biocapacity is under constant pressure. On a sustainable planet, all of humanity would only use the resources and produces waste at a level that does not deplete nature. The ecological footprint, measured in global hectares (gha) for the average biological productivity in a given year allows to put the actual global hectares that are consumed (and wasted) into the context of the existing biocapacity. With changing consumption patterns and population developments, the gap between these two has been growing constantly and exceeds the biosphere’s regenerative capacity. This map shows this overconsumption from the perspective of the world's population, visualising the extent to which people overuse the world’s natural resources colour coded by multiples of the carrying capacity of the planet in 2019.]]> This map shows the land surface resized by its population overlaid with data about each country’s ecological footprint measured in global hectares consumption per capita.

Data sources
This map uses population estimates for the year 2020 are based on data from the Gridded Population of the World (GPW), v4 at 0.25 degree resolution, released by SEDAC (Socioeconomic Data and Applications Center). The map overlay uses data from Global Footprint Network, National Footprint and Biocapacity Accounts 2019 Edition (last accessed: July 2019).

Each transformed grid cell in the map is proportional to the total number of people living in that area multiplied by their respective national ecological footprint measured in global hectares consumption per capita.

[...] Gross primary production (GPP), shown here, is the total amount of carbon dioxide 'fixed' by land plants per unit time through the photosynthetic reduction of CO2 into organic compounds." Quoted from Gough, C.M. (2011) Terrestrial Primary Production: Fuel for Life, Nature Education Knowledge 3(10):28. Read more and see an animated version of this map in our blog]]> This map shows the land surface resized according to its annual gross primary production (GPP) in terms of their carbon currency (g C m-2). Each transformed grid cell in the map is proportional to the total annual production in that area which is also indicated through the colours that are overlaid. GPP is the net amount of energy that is produced by the main energy producers of an ecosystem.
Production is determined by first computing a daily net photosynthesis value which is then composited over an 8-day interval of observations for a year.
