Out of Africa: Humanity’s Journey around the Planet

Featured

It took a long time for humankind to move out of Africa and inhabit the rest of the planet. Archaeological research and genetic studies based on fossils found in plains of east Africa suggest that modern humans evolved nearly 200,000 years ago. Palaeontological findings and genetic footprints are also the basis for current theories of how modern humans (Homo sapiens) started spreading around the globe. Such models and timings keep changing, with new discoveries being made on a fairly regular basis.
The below map illustrates the migration of humanity across the Earth with all movement originating in Africa and with the estimated dates of arrival shown at key directions and locations. The dates are based on a number of scientifically validated estimates. They build upon the ‘Out of Africa’ model that assumes the spread of modern humans from their African origins across the globe, superseding any other human species that had lived in parts of the planet before (and sometimes as) Homo sapiens arrived.

The World in 2016

Featured

The world is ever changing. This year, we live on a planet of 7.4 billion people who contribute products and services worth approximately US$80 trillion in nominal terms. However, population and wealth as measured in GDP activity are not distributed equally across the world which remains one of the challenges of our time. The following two cartograms illustrate this by highlighting where people are and where in contrast GDP wealth is made – the unequal distributions in our world today are quite obvious:

Nuclear Europe

30 years ago on this day the nuclear accident of Chernobyl brought the risks of nuclear energy production closer to the European population. Alongside the United States, Europe has the most dense network of nuclear power plants in relation to its population, as the below map shows. Of the producers of nuclear power in Europe, France (17.1%) and Russia (7.0%) are the largest when comparing it to the global share (France comes second after the USA). The United Kingdom’s production accounts for 2.9%. In contrast, France generates the largest share of its domestic electricity generation from nuclear power (74.4%) worldwide. It is followed by Sweden (43.4%) and Ukraine (43.0%), while the United Kingdom comes fifth with 19.2%.

World Population Cube

Featured

World Population CubeLast November’s theme of the Super Science Saturday at the Oxford University Museum of Natural History was Planet Earth. As part of the activities I contributed a map cube which I created a few years ago.
Cubic globes are not a new idea. They put a nice twist to showing just a simple map, and more importantly, they allow for some activity which get the kids involved just as much as adults. A cube is much less work than creating a spheric version of Earth, and (as said by Carlos Furuti on his online cube globe collection) the cube is an ideal introduction to folding one’s own pseudoglobes.
At last November’s Super Science Saturday I displayed some of my work and offered a ‘Map Cube Activity’ where children (and adults) could cut, fold and glue their own globes. My version of a map cube does not display a normal world map, but a gridded population cartogram (hence the name ‘World Population Cube’). You can create your own cube by using the following template: Continue reading

The Growth and Decline of Urban Agglomerations in Germany

Innovative maps that illustrate the most recent socio-demographic urban changes in the major city urban agglomerations in Germany have very recently been produced in a joint project of the School of Geography and the Environment at the University of Oxford and the Research Institute for Regional and Urban Development Dortmund (Germany).
The Research Institute for Regional and Urban Development (Institut für Landes und Stadtentwicklungsforschung, ILS) investigates new social processes, especially those involving urbanisation in Germany and Europe. This includes economic, social and structural processes that are compared and monitored over time to gain a better understanding of the underlying developments. Testing state-of-the-art visualisation techniques are a significant part of this effort. This was the focus of a collaboration between researchers of the University of Oxford and the ILS Dortmund which resulted in the development of a series of highly effective maps called “cartograms” that provide new insights in the changing geographies of city regions in Germany.
