Connecting people: A world map of undersea cables

Featured

Despite satellite technology, global communication heavily relies on undersea cables to keep people connected. “A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean.” (Wikipedia) Undersea cables are the backbone of the internet, so that being connected determines a region’s ability to participate in global communication flows.
The following cartogram shows data from Greg’s Cable Map reprojected onto an equal population projection, giving a perspective of how people rather than land areas are connected to the global communications infrastructure. Landing points where the cables connect to land are marked as red dots in the map, while the background also shows very faded shipping lanes (over sea) as well as the gridded cartogram projection (over land):

Home Ownership in Britain

Featured

Housing has always been a decisive and sometimes divisive political issue. Home ownership has of course long been an aspiration for many people, and in the post-war period between 1953 and 1971 the number of households renting and owning reached an equal level, as documented in official census statistics for England and Wales. Ownership then surpassed renting, reaching its peak in 2001 at 69%. In the decade that followed, this number went down to 64%. The following two maps show the ownership rate in the UK in a conventional and an equal population projection:

Nuclear Energy and Risk

Featured

Nuclear power contributes only a small share to the global energy production. According to the World Energy Statistics 2015 published by the International Energy Agency (IEA) nuclear power accounts for 4.8% of the total primary energy supply worldwide, far behind oil (31.1%), coal (28.9%), natural gas (21.4%) and even behind biofuels and waste (10.2%).
Of the producers of nuclear power, the United States are by far the largest with 33.2% of the world’s total, followed by France (17.1%) and Russia (7.0%). 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%). It is followed by Sweden (43.4%), Ukraine (43.0%) and South Korea (25.8%), while the United Kingdom comes fifth with 19.2%.

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.

Beyond fire and ice: Mapping Iceland in the 21st Century

Featured

Iceland and maps have a long tradition in the history of cartography. From the first maps of the country in the 16th century (including works from cartographers such as Ortelius and Mercator, also featuring some nice sea monsters) to today’s advanced digital mappings of Iceland’s diverse natural environment (such as this innovative mapping of water in Iceland or this quite beautiful representation of contour lines), Iceland never really had a lack of quite good cartographic works. Much less covered than the natural environment are the social landscapes of the country, such as this just recently updated version of a gridded population cartogram of the country where each grid cell is proportional to the number of people living in that area:

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%.
