Species at Risk

Trying to get a picture of where and how many species globally are endangered or even at risk of extinction is a difficult undertaking. For 50 years the International Union for Conservation of Nature (IUCN) publishes the red list of threatened species. The list is a “comprehensive information source on the global conservation status of animal, fungi and plant species and their links to livelihoods”. It contains over 77,000 species of which according to the most recent report more than 22,000 are at risk of extinction. IUCN considers species at risk when they are “critically endangered, endangered or vulnerable.
Mapped here is data from the International Union for Conservation of Nature’s (IUCN) Red List of threatened species including endangered and vulnerable species. The main cartogram shows countries resized according to all animal and plant species assessed as being at risk of local extinction. The two smaller cartograms highlight that conservation efforts have very different spatial degrees of severity, which also partly reflects the different geographical distribution of species.

Trainspotting: Europe’s railway lines

Featured

Passenger transport in Europe is largely dominated by cars. In the past decade, cars kept a consistent share of around 83 per cent of the modal split within the European Union, followed by buses and coaches (around nine per cent in most recent statistics) and trains (between seven and eight per cent). The modal split describes these modes of transport as ‘transport kilometres travelled by all inland passengers’. In the debate about sustainable development, this is an important measure to monitor the environmental and social impacts of the specific modes of transport.
Cars are generating the most emissions and pollution per passenger kilometre and also have significantly higher accident rates. Mass transit and public transport, including buses and coaches as well as trains, are therefore regarded as the more sustainable alternatives and have regained importance in urban and regional planning.
Buses rely on the same transport infrastructure as cars, while trains require railway tracks in order to maintain or improve the existing transport capabilities. Recent trends showing a slow but steady revival of passenger transport by train in Europe therefore have to be seen in the context of its existing transport infrastructure. New railway infrastructure is costly and requires time-consuming planning procedures.
A look at the railway infrastructure in Europe (beyond the EU) shows that across the continent there are approximately 250,000 km of tracks, just slightly lower than the length of tracks in the USA, where train travel plays a subordinate role in passenger transport but serves mostly freight transport.

Unequal Elite: World University Rankings 2016/17

Featured

Education and money undoubtedly go hand in hand. A closer look at the metrics that go into the creation of higher education rankings such as the Times Higher Education’s World University Rankings (THE WUR) proofs just the point that without adequate resources and funding global success can hardly be achieved. The following map which was created by analysing data of the 2016/17 World University Ranking data with regards to its spatial distribution of the most successful universities in this ranking. The map is a gridded cartogram which is reshaped to show national wealth, measured by gross domestic product. The land area in each country has been resized to reflect economic output. North America and Western Europe bugle to dominate this world map, while the entire continent of Africa virtually disappears. On this new world map, all the universities in the THE World University Rankings are plotted, with the larger, red dots representing world’s top 50 universities and the smaller circles representing the lower ranks:

Political Landscapes of the United Kingdom in 2017

How much has the United Kingdom changed following the second general election within two years, and following the referendums on independence in Scotland in 2014 and the membership of the European Union in 2016? Each poll appeared to have had a significant impact on the political debate and the next vote which never seemed far away. As such, the 2017 general election looks like the culmination of the preceding ballots where all of the previous debates got a more or less prominent mention during the electoral campaign. Ultimately this led to some significant changes in the political landscapes of the country with each corner of the United Kingdom being affected by these dynamics.
Politicians, spin doctors and commentators quickly aim to interpret the outcome according to their views. In contrast, the following series of maps showing some key statistics and data from the election results aims to provide a more neutral as well as more comprehensive look at the underlying geographies. It shows different angles on key characteristics such as winners and runners-up in each constituency, changes in votes, vote shares of the two largest parties, turnout and changes in turnout between the last two general elections.
In this feature, different cartographic techniques are used to show how the electoral landscape in the UK is shaped not only by physical space, but also by political dimensions as well as from the perspective of people. The conventional (land area) map is therefore complemented by a hexagon cartogram where each parliamentary constituency is represented by a hexagon (some changes in constituencies over the past decades are reflected in split and merged hexagons), and by a gridded population cartogram where each area is resized according to the number of people living in that area.
Each of the three maps therefore provides a unique insight into the diverse spatial patterns of politics that emerged from the 2017 general election. To fully understand the new political landscapes of the United Kingdom, only a combination of different perspectives as shown here can help to gain a more complete picture. Geography matters not only in its physical dimension, but just as much in its social and political spaces that are depicted in these maps.
Here is the ultimate cartographic wrap-up of the 2017 general election in 21 maps:

Britain elects: The changes

Featured

Nothing has changed” was the infamous quote made by Theresa May during this year’s UK election campaign over a policy u-turn. This marked the beginning of a reverse of the Conservative support in the polls which eventually led to the changes that changed the political geography of the United Kingdom significantly when compared to the just as surprising result of the 2015 election. The following map uses the same approach as the previous map series showing the winning party in each constituency, but adds further detail to the picture by also highlighting how seats have changed between the last and this election:

Britain elects: The results (summer edition 2017)

The United Kingdom went to the polls…again. Following the general election in 2015 and the referendum on the country’s membership in the European Union in 2017, the British electorate had yet another chance to have their say about the country’s future. After the then prime minister David Cameron delivered referendum which he had promised to win the 2015 election, the British electorate voted for leaving the European Union by a small majority of 51.9% which led to Cameron’s resignation. Theresa May took over leadership of the Conservative party and became Prime Minister in July 2016. After first resisting calls for a general election, she eventually decided otherwise in the expectation of strengthening her conservative majority during the Brexit process. However, the election on June, 8th led to the opposite. The Conservative party lost its majority in parliament with the Labour party making significant gains. The following map series shows the result of the election from three perspectives. The conventional map (left) provides the most common perspective, while the hexagon-map gives a clearer picture of the distribution of parliamentary seats where each seat is represented by a hexagon (middle, changes in constituencies results in some hexagons being split). The gridded population cartogram (right) provides the most accurate depiction of how many people are represented by each party, as it gives each person in the UK an equal amount of space (while constituencies vary sometimes significantly in their population size):
