"Why are all the gas stations, cafes and restaurants in one crowded spot? As two competitive cousins vie for ice-cream-selling domination on one small beach, discover how game theory and the Nash Equilibrium inform these retail hotspots."
Scientists have issued a new warning to the world’s coastal megacities that the threat from subsiding land is a more immediate problem than rising sea levels caused by global warming.
A new paper from the Deltares Research Institute in the Netherlands published in April identified regions of the globe where the ground level is falling 10 times faster than water levels are rising - with human activity often to blame.
In Jakarta, Indonesia’s largest city, the population has grown from around half a million in the 1930s to just under 10 million today, with heavily populated areas dropping by as much as six and a half feet as groundwater is pumped up from the Earth to drink.
The same practice led to Tokyo’s ground level falling by two meters before new restrictions were introduced, and in Venice, this sort of extraction has only compounded the effects of natural subsidence caused by long-term geological processes.
"For 75 years, Finland's expectant mothers have been given a box by the state. It's like a starter kit of clothes, sheets and toys that can even be used as a bed. And some say it helped Finland achieve one of the world's lowest infant mortality rates."
"This animation distils hundreds of years of culture into just five minutes. A team of historians and scientists wanted to map cultural mobility, so they tracked the births and deaths of notable individuals like David, King of Israel, and Leonardo da Vinci, from 600 BC to the present day. Using them as a proxy for skills and ideas, their map reveals intellectual hotspots and tracks how empires rise and crumble. The information comes from Freebase, a Google-owned database of well-known people and places, and other catalogues of notable individuals. The team is based at the University of Texas at Dallas."
Elizabeth Borneman explores how cartography and cartographic projections help and hinder our perception of the world.
"How do you think the world (starting with our perceptions) could change if the map looked differently? What if Australia was on top and the hemispheres switched? By changing how we look at a map we truly can begin to explore and change our assumptions about the world we live in."
Geography doesn’t just teach us about the Earth; it provides ways for thinking about the Earth that shapes how we see the world. Maps do the same; they represent a version of reality and that influences how we think about places.
"The global Multidimensional Poverty Index (MPI) is an international measure of acute poverty covering over 100 developing countries. It complements traditional income-based poverty measures by capturing the severe deprivations that each person faces at the same time with respect to education, health and living standards."
In 1990, the manufacturing industry was the leading employer in most U.S. states, followed by retail trade. In 2003, retail trade was the leading employer in a majority of states. By 2013, health care and social assistance was the dominant industry in 34 states. This animated map shows the top industry in each state and the District of Columbia from 1990 to 2013.
"More Americans came into contact with maps during World War II than in any previous moment in American history. From the elaborate and innovative inserts in the National Geographic to the schematic and tactical pictures in newspapers, maps were everywhere. On September 1, 1939, the Nazis invaded Poland, and by the end of the day a map of Europe could not be bought anywhere in the United States. In fact, Rand McNally reported selling more maps and atlases of the European theaters in the first two weeks of September than in all the years since the armistice of 1918. Two years later, the attack on Pearl Harbor again sparked a demand for maps."
"With seven billion people now living on Earth, the ever growing demand is putting unprecedented pressure on global resources—especially forests, water, and food. How can Earth’s resources be managed best to support so many people? One key is tracking the sum of what is available, and perhaps nothing is better suited to that task than satellites."
Without a question, we are living in an urban era. More people now live in cities than anywhere else on the planet and I’ve repeatedly argued that cities are our most important economic engine. As a result of these shifts, we’re seeing megacities at a scale the world has never seen before.
"Population statistics are like crystal balls -- when examined closely, they can help predict a country's future (and give important clues about the past). Kim Preshoff explains how using a visual tool called a population pyramid helps policymakers and social scientists make sense of the statistics, using three different countries' pyramids as examples."
