Changing Political Landscapes of Britain

Featured

Three days after the UK general election, the formation of a new (old) Conservative government is in full preparation with few new faces on the one side, and soul searching and the search for new faces on the other side of the political spectrum. There has also been plenty of joy for map lovers (even if they may not be equally happy with the outcome), including my own map series of the winning parties in each constituency. The following map series uses the same approach but shows further details on how things have changed in the political landscape of the country compared to the 2010 general election:

Views of the 2015 UK election

The 2015 general election in the United Kingdom has ended with a very unexpected outcome resulting in a much clearer outcome as predicted in the polls. The Conservative Party with the old and new Prime Minister David Cameron has secured a majority in the new parliament, winning 331 of the 650 seats. As the BBC concludes: “The Conservatives win a 12-seat majority in parliament as Labour are almost wiped out by the SNP in Scotland and the Liberal Democrats suffer major losses.”
Looking at the election results in a conventional map, this very clear outcome becomes even stronger, with much of the map being dominated by blue (for the Conservatives) and yellow (for the Scottish National Party). Very little consolation for the main losers, but a more honest picture emerges, when changing the perspective, as shown in the following map series. The hexagon map shows the real political representation as it emerges in the Westminster Parliament, with every constituency being coloured according to the winning political party there. The third map in the series is an equal-population projection which gives every person living in the UK the same amount of space, so that the true picture of how people are being represented is painted. The latter differs slightly from the constituency view, as the constituencies in the UK are not only differing in (land area) size, but also in population size (which is part of a critical debate about electoral reform). So here is the complete picture of the 2015 general election:

Global Gender Inequality

Featured

The unequal treatment of individuals based on their gender is a deeply rooted problem in most societies. It started becoming an important part of academic research in the 1980s. The issue of gender inequality also became in various measures part of the Human Development Index (HDI), the annual report by the United Nations Development Programme (UNDP), and was eventually integrated as the Gender Inequality Index (GII) in the 2010 report. It is designed to measure the loss of achievement within a country caused by gender inequality.

Earthquake risk zones: A people’s perspective

Featured

A M7.8 earthquake has occurred in Nepal “as the result of thrust faulting on or near the main frontal thrust between the subducting India plate and the overriding Eurasia plate to the north.” As the USGS summarises, “although a major plate boundary with a history of large-to-great sized earthquakes, large earthquakes on the Himalayan thrust are rare in the documented historical era. Just four events of M6 or larger have occurred within 250 km of the April 25, 2015 earthquake over the past century”.
In a paper for the Journal of Maps published in 2014 I have analysed and visualised data documenting earthquakes that have occurred since 2150 BC. The following map was part of the material supplementing the publication showing the results of the analysis shown on an equal population projection. The gridded cartogram gives every person on the planet an equal amount of space while highlighting the most densely populated spaces in relation to the earthquake risk (calculated via the intensity of earthquakes recorded since 2150 BC). Also shown are the world’s megacities (over 5 million population). The map shows the large populations that make even Nepal (with its almost 28 million people) much more visible than it would be on a conventional map, highlighting why this event turns out to be quite disastrous. The map also shows what the USGS statement above mentions that Nepal is amongst the areas in the region which are far less subject to major earthquakes (as indicated by the yellow to blue shading in the map there – Nepal is the rather large spot squeezed on top between the areas that represent the large populations of India and China):

Healthy Soils for a Healthy Life

International Year of SoilsHealthy Soils for a Healthy Life is the motto of the UN International Year of Soils which aims to “increase awareness and understanding of the importance of soil for food security and essential ecosystem functions.” As explained on the campaign’s website, “soil is the thin layer of material on the Earth’s surface. It is a natural resource consisting of weathered and organic materials, air and water. As it is the medium in which plants establish themselves and grow, the most widely recognized function of soil is its support for food production. Soil provides nutrients and water that are absorbed through plant roots and contribute to the regulation of water and atmospheric gases and therefore play an important role in climate regulation.”
Soil therefore matters most where is is near human population, which at the same time puts soils under extreme pressure in these areas. Soil types not least determine where humans used to settle when they gave up their nomadic lifestyles and started becoming more stationary as farmers. Nowadays, some of the most fertile soils are found in the most densely populated spaces on the planet, which is shown in the following map. The map shows the major soil types classified in the FAO/UNESCO Soil Map of the World reprojected on a gridded population cartogram where a grid is resized to give every person living within a grid cell an equal amount of space (reducing the map in those spaces most where there are fewest people):

The Evolution of Life Expectancy in the World

Featured

Life expectancy equals the average number of years a person born in a given country would live if mortality rates at each age were to remain constant in the future.” (Wikipedia)
Depending on the exact sources, global life expectancy currently lies at approximately 71 years although a global estimate tells very little about the differences between the countries. What applies to every country is the fact that women, on average, live longer than men.
The following map shows the distribution of life expectancies based on national-level data as documented in the 2014 revision of the Human Development Report displayed on a gridded population cartogram in which every human gets an equal amount of space:
