Views of the World at Night

The Sendai earthquake in Japan sparked a debate about sustainable energy supplies of industrialised countries – with a controversial discussion about the safety and sustainability of nuclear power. The book ‘Sustainable Energy – without the hot air‘ by David MacKay is an outstanding read in this regard, outlining the all key issues that matter for our future energy need (the digital version is free, although I recommend the paperback which can even be read without wasting any electricity).
Switching the lights off was not a matter of choice for many people in the North of Japan after the devastations of the earthquake also affected the energy supplies (not only because of the Fukushima accident, but also because of a widely destroyed basic infrastructure). Another image featured in the NASA Earth Observatory takes a closer look at the electricity losses that occurred after the Earthquake by creating a composite image of two images of lights observed in 2010 and after the earthquake at March, 12 this year. As a highly industrialised country, the illuminated areas in Japan usually show the places where people live (see worldmap below), while dark areas are the unpopulated regions, hence the reprojection on a gridded population cartogram results in a dominantly bright image. Using NASAs display of the electricity losses therefore gives a good representation of the number of people affected by the power losses (and largely also the Tsunami and Earthquake itself) in the Northeast: The redrawn version of the image shows these as the red areas, while the brighter yellow areas in the South and West show the regions that has a similar illumination compared to the previous image. This is how ‘Japan at Night’ looked after the 2011 Earthquake:

World Water Day

World Water Day 2011

Water is a basic requirement for all life, yet water resources are facing increasing demands from, and competition among, users. In 1992, the UN General Assembly designated 22 March of each year as the World Day for Water
(quoted from the WWD website).

Water is more than a chemical substance contains one oxygen and two hydrogen atoms. Water has become a reason for conflicts and a controversial commodity, and yet, it is inevitable for every human being on the planet. The range of issues that are important when looking at water is diverse, and all fields reveal the global inequalities in access to clean water. One of these issues is the commercialisation of water, which on a global scale finds its manifestation in the bottled water industry: Bottled water is one way of getting access to clean water if there is no reliable central water supply or local source of water.
Edward Stanley from University College London looked at the bottled water business for a Geography dissertation project, for which I created some worldmapper maps visualising his data from that research on ‘Commodification and Mass Consumption – The Case for Bottled Water‘.
The topics that we mapped focus on the countries of origin of the globally operating bottled water companies and the bottled water consumption in the world. The first map shows the total bottled water consumption including a world population cartogram as a reference. In addition, the countries are shaded by their per capita consumption of bottled water (a worldmapper-style version of this map is shown at the bottom of this page):

The International Year of Forests 2011

International Year of Forests 2011The United Nations General Assembly declared 2011 as the International Year of Forests (IYF) to raise awareness on sustainable management, conservation and sustainable development of all types of forests. The British Prime Minister Cameron experienced, how forests can become a very political issue, which shows how emotional people’s attitude towards their environment can sometimes become. The International Year of Forests, however, was never mentioned in the debate that went on during the proposed forest sell-off by the British government, which highlights one of the problems that sometimes these proposed International-Years-of-Something face: A lack of attention. On a global scale, 31% of the land area is covered by forests. Some of these areas are highly under threat by unsustainable forestry and environmental pollution. The IYF therefore is meant to emphasise “the need for sustainable management of all types of forests, including fragile forest ecosystems” (UN resolution on the IYF). Continue reading

Wealth increase 2010-2015

Some recent maps on this website were closely related to the direct or indirect implications that the global downturn had on people’s lives across the globe: Be it the slowed-down but still growing carbon emissions, the poor state of well-being seen from a more sustainable point of view, or the distribution of wealth.
How this all related to each other has recently been commented by Peter Victor in Nature, who argues that “our global economy must operate within planetary limits to promote stability, resilience and wellbeing, not rising GDP” (Questioning economic growth, Nature 468: 370–371).
The previously published GDP map on the global distribution of GDP for 2010 and 2015 gives a good indication how little the distribution of global wealth has changed, and where the nations of the world are that may reconsider their attitude towards further growth. The map is less useful to see the dimension of changes and to see how little things have changed so far: The rich countries getting richer and the poor countries trying to catch up with these developments – and still, rising levels of global inequalities and further socio-economic disparities. This is shown in the following map, which displays the absolute growth derived from the GDP estimates for 2010 and 2015. The map thus shows the countries resized to the total growth that is expected for all countries in the given timespan and gives a clear picture of where the growth is largest (apparently, G20 countries dominate much of this cartogram. The colour key for the countries adds another dimension by showing the rate of growth reached 2015 compared to the level of 2010, an indicator that shows the most dynamic economies in the years to come – and those which kept on producing more carbon emissions despite the recession:
