The current global network of protected areas is quite extensive, covering 17 million square kilometers of land and 2 million square kilometers of oceans. But the more than 100,000 areas appear to be insufficient to halt global biodiversity loss, according … Continue reading
This year we will hit 7 billion. But the big demography news is not just the net growth figure, but also the differentiation – where it takes places. A new Harvard study has sifted through the billions of unborn people … Continue reading
Two more decades of growth for China, four more for India: within 40 years the world’s two population giants will together inhabit close to 3 billion people.
In our new demography series we compare population growth for sets of countries, based on the UN World Population Prospects 2010 Revision, which was released last month. To better illustrate that global population growth is far from uniform, today we … Continue reading
Today our comparing population growth series continues. This time we compare Turkey to several of its neighbouring states: Greece, Georgia, Armenia and Iran. If ever again [1;2] you hear anyone say ‘demography is economic development,’ point to this graph:
The world population is growing, but that growth is far from uniform. In our new series on the demographical situation in the world we zoom in on the UN World Population Prospects 2010 Revision that was published last month – … Continue reading

Ask engineers and they’ll say there is an engineering solution to any problem. With respect to climate change and geoengineering that’s hotly debated, with respect to overpopulation it’s a novelty. Today the UK-based Institution of Mechanical Engineers presented a report … Continue reading
