The Koriak represent one of the indigenous populations of Russia's northern region of Kamchatka in Siberia. They migrate with the reindeer over vast and rugged tundra and live from their bi-products. Decades of Soviet rule have marginalised the Koriak. Since the fall of communism the Koriak are free to practise their traditional festivals and way of life however their numbers are worryingly on the decrease.

Another victim of Soviet oppression are the Tsaatans of Mongolia. Their name means, "People of the Reindeer". Like the Koriak, the religion and shamanic rituals of the Tsaatans have been destroyed after more than sixty years under Soviet rule. What they have left are the reindeer.

We know of the beaches, Carnival and raunchy nightlife of Rio de Janeiro so it was quite a pleasant change to discover another side to Rio. Travelling through the suburb of Santa Teresa on "Bonde" the oldest tramway in the world, it's as though time has stood still here since the 19th century period of the Belle Époque, when the artists, writers, intellectuals and wealthy art patrons made it the Montparnasse of Rio.
