Major cities in the Andean community Major cities in the Andean community
The urbanisation of the population has been happening since the first city, and is rapidly increasing in rate - especially since the dawn of industrialization. The Andean community consists out of five countries: Venezuela, Colombia, Ecuador, Peru and Bolivia - that are in the middle income class. The fast growing cities create new problems, like slums, sewage and the supply of resources.

Rural and urban population in the Balkans Rural and urban population in the Balkans
In the meantime, the rural exodus is continuing all over the region, particularly in Albania where people are deserting mountain areas and the population of Tirana has risen from 200 000 at the end of the communist era to almost a million. The newcomers cram into the city outskirts lacking any proper infrastructure. A similar pattern may be seen in Belgrade, Sarajevo and Skopje.

Urban water supply and wastewater on a shallow aquifer Urban water supply and wastewater on a shallow aquifer
This graphic shows the changes in water supply and wastewater disposal that occur through four stages of growth of a settlement: early settlement; the town becomes a city; the city expands and the city expands further. The changes include increased groundwater pollution and changes in pluvial drainage, the water table and wellfields.

No shelter - refugees, sanitation and slums No shelter - refugees, sanitation and slums
In the face of any calamity we instinctively take refuge under a roof. This is little use against a chemical or nuclear accident, but for many there is no other resort. The number of people currently living in shanty towns is rising in all the big cities of the developing world, where urban growth is generally uncontrolled. The map shows how small the proportion of city dwellers with improved access to sanitation in many places is, giving an ide...

Ice avalanches of the Nevados Huascarán in Peru Ice avalanches of the Nevados Huascarán in Peru

On 10 January 1962, an ice avalanche took place with an estimated starting volume of 10 million m3; the avalanche travelled down 16 km and destroyed the city of Ranrahirca, where 4000 peop...

Population and main oil and gas production areas in the Arctic Population and main oil and gas production areas in the Arctic
The Arctic represents one of the least populated areas in the world, with only sparse settlements and very few large cities and towns - in comparison with e.g. continental Europe. The largest cities are in Northwest Russia, and Reykjavik is the only national capital in the Arctic. The extraction of natural resources has emerge as a main interest and priority in the Arctic region, and this may cause increases and shifts in population.
