"Shakespeare’s Coming Home," boasts the strapline of a highly ambitious strand of London 2012’s Cultural Olympiad. Between now and 9 June, 37 productions of the complete canon by Shakespeare (with apologies to Two Noble Kinsmen fans) will be seen at Shakespeare’s Globe by 37 different theatre companies from all over the world. Hence the catchy title, Globe to Globe, which forms only a part of a World Shakespeare Festival continuing until September and taking place all over England and Wales, from Stratford-upon-Avon to the National Eisteddfod.

Footage of wiry East African men and women breaking the tape in marathons and distance track-events is now more or less synonymous with the highest achievements in top-level sport, and it won’t come as a surprise to those who’ve lived through more than a couple of cycles of the Olympic Games to be reminded that the medal-winners in the long-distance running events are no longer, generally speaking, from “round here”.

The 18th-century Omani fort in Zanzibar is silhouetted against a clear African night. Nneka, a bird-like Nigerian female artist in shabby leggings, is hammering out “Vagabonds in Power” on an open-air stage inside the fort, just metres from a sea of entranced faces. The song is a poke at Africa’s leaders, specifically their part in the Niger Delta mismanagement and related death and corruption scandals. With a voice reminiscent of Nina Simone, and the emotional clout of Billie Holiday, Nneka delights the predominantly African crowd attending the Busara festival.

With the subject of the legitimacy of the label “world music” having just had another airing in The Guardian, it seems fitting that Mali’s favourite musical couple should be releasing their least “world music” album to date. For essentially, Folila (which translates as "music" in Bambara) is a blues/rock album.

In the past few decades we've all learnt to pay at least lip service to ecological matters, and millions of people in this country are members of environmental organisations. But perhaps we should also focus our attention on an issue that could be one of the big causes of the 21st century - the disappearance of languages.

Two hundred years ago in Durham taverns you could find men in wooden clogs clattering on the tables, with their mates pressing their ears to the underside of the surface. Meanwhile, at the other end of the world, African slaves with bare feet were shuffling on dirt with metal bottle caps held between their toes. Now picture a Mediterranean gypsy dancing of sorrow and pain with swirling shawls and angrily pounding heels. Three quite different scenes, different places, different eras, but all rooted in one human impulse, common the world over.

Last night was one of those occasions when I found myself looking forward to seeing the support band more than the main act. This wasn’t because Senegal’s sublime Orchestra Baobab haven't delivered a transportive heart-warming set of Cuban and soukous grooves every time I’ve seen them live. It was simply because Belgium-based Congolese rapper Baloji made Kinshasa Succusale - one of my favourite albums of last year.

When I opened my e-nvitation to write up last night’s The World Against Apartheid, I was not expecting it to come bedecked with GoogleAds for hen parties, roller discos, and custom-made birthday invitations (keyword: "part/y", one assumes). Only 20 years ago, any mail on this topic would’ve been stuffed with "End racism NOW!" leaflets, discount book offers by/about Basil D’Oliveira, and pop-up Peter Hains beseeching you to boycott your local fruiterers. Twenty years ago "The World Against Apartheid" would have been a call to arms.

London's Barbican Centre is 30 this year, and with a special Olympics subsidy boost as the world's eyes turn to the British capital this summer, it aims to be as lovely inside as it is famously unlovely outside. Film beauties Cate Blanchett and Juliette Binoche appear live on stage and theatre giants Pina Bausch, Philip Glass and Shakespeare are celebrated in a season of prominent internationalism. Peter Sellars, Toni Morrison, Yukio Ninagawa, Krzysztof Penderecki and Chick Corea are among many other world names invited to EC2 over the season.
