"The Sahel’s ability to produce food is not keeping pace with its growing population, and global warming will only exacerbate the imbalance, according to a new study. Among the 22 countries making up the arid region in northern Africa, the population grew to 471 million in 2010 from 367 million in 2000, a jump of nearly 30%. As the population grew rapidly, the production of crops remained essentially unchanged. Using satellite images to calculate annual crop production in the conflict-ridden Sahel belt, south of the Sahara desert, the researchers then compared output with population growth and food and fuel consumption."
"By 2025, the developing world, as we understand it now, will be home to 29 megacities. We explore the latest UN estimates and forecasts on the growth of these 'cities on steroids', and take a look at the challenges and opportunities megacities present for the tens of millions living in Lagos, Mexico City and Dhaka."
"There are 1.2 billion people between the ages of 15 and 24 in the world today — and that means that many countries have populations younger than ever before. Some believe that this 'youth bulge' helps fuel social unrest — particularly when combined with high levels of youth unemployment. Youth unemployment is a 'global time bomb,' as long as today’s millennials remain 'hampered by weak economies, discrimination, and inequality of opportunity.' The world’s 15 youngest countries are all in Africa. Of the continent’s 200 million young people, about 75 million are unemployed.
On the flip side, an aging population presents a different set of problems: Japan and Germany are tied for the world’s oldest countries, with median ages of 46.1. Germany’s declining birth rate might mean that its population will decrease by 19 percent, shrinking to 66 million by 2060. An aging population has a huge economic impact: in Germany, it has meant a labor shortage, leaving jobs unfilled."
Tripoli, 20 September 2013: Libya, Egypt, Chad and Sudan have signed a UN-backed agreement on the shared use of a massive underground aquifer system straddling the four countries known as the Nubian Sandstone Aquifer System.
"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."

"Argentina should be careful in considering the implications of the idea of moving the capital [from Buenos Aires] to Santiago del Estero. While a dramatic move might be appealing as a fresh start, it could end up aggravating the challenges of governing the country. Capitals, like flags, are symbols, but their choice has very real consequences."
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.

"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."
This blogpost answers the (often unasked) question: What would the world be like if the land masses were spread out the same way as now - only rotated by an angle of 90 degrees? While purely hypothetical, this is an exercise in applying real geographic thinking to different situations. Anything that you would correct?
