Rio de Janeiro: Countdown to the Olympic Opening Ceremony – Steve Scott

There are less than 100 days to go until the curtain raises on the Olympic Games in Rio de Janeiro, but already political turmoil and high drama threaten to overshadow Brazil's showcase event. Nationwide protests, claims of corruption, the country's president now impeached: hardly the best build up to the world's largest sporting event. Add into the mix the devastating Zika virus and a crippling economic recession, and Brazilians could be forgiven for not feeling optimistic about the games.

But that is not the Rio way. This is a city that lives for a party and one party in particular: Carnival. Early every year, the city's streets come alive to a dazzling bombardment of the senses as revellers compete to be the most striking, colourful and vibrant show in town - played out to the irresistible rhythms of the Samba. It is exactly this spirit the games organisers are hoping to harness at the Olympic opening ceremony and make it a night to remember. Steve Scott has been to Rio to get a privileged glimpse behind the scenes as preparations gather pace and meets the city's charismatic mayor, who in the current political vacuum has been thrust further into the spotlight. Is he still confident the games will put Rio on the map for all the right reasons?

LA: Food deserts – Nina Nannar

For years Nina Nannar has covered the Oscars for ITV News, but this year she left the glitz and glamour of Hollywood behind for the Los Angeles suburb of Watts to meet the chefs on a mission to bring healthy eating to the streets of LA's poorest neighbourhoods. Once synonymous with riots and violence, today Watts faces a different challenge. Without even a supermarket in town, residents say that the lack of healthy, affordable food has created a reliance on cheap fast-food outlets and a serious obesity problem.

But Daniel Patterson and Roy Choi, two of California's most celebrated chefs, are determined to make a difference with their new breed of fast food which promises something healthier, delicious and nutritious at a price people can afford. Even Aqeela Sherrills, a former gang member, who once brokered a peace deal between the notorious Bloods and Crips gangs in the ‘90s has taken on this new fight against obesity. With Nina he hits the streets in his food truck, delivering free fruit smoothies and spreading the word about healthy eating to a young generation hoping for bright future.

AUSTRIA – James Mates

Could Austria become the first European country since World War II to democratically elect a far-right president? The polls show Norbert Hofer neck-and-neck with progressive opponent Alexander Van Der Bellen, who won the presidential election in May by a slim margin. Hofer's hopes have been reignited after the country's constitutional court decided to annul the election outcome after irregularities in the process were revealed and has now set a re-run for November. James Mates travels to Vienna and the surrounding countryside to explore the opposing perspectives dividing Austrian society. Could this lead the country to be the next member state to turn its back on the European Union?

TANZANIA – John Ray

In Tanzania on Africa's east coast, criminal gangs are increasingly using explosives to stun and kill fish - allowing easy collection and larger hauls. Yet their methods are having a devastating effect on the local ecosystem and entail potentially fatal consequences for the fishermen involved. Records reveal that there have been 8,700 explosions in just 14 months, resulting in thousands of metres of East Africa's most pristine coral reefs being destroyed. John Ray travels to the markets of Tanzania where dynamite is freely available and meets a fisherman who lost his hands to this dangerous and destructive practice.

ESTONIA: SPLIT BY A BORDER - Simon Harris

The Seto people in South East Estonia are one of the last folk cultures in Europe and are fighting to preserve their unique way of life. Simon Harris visits them on one of their most important religious holidays where they feast on the graves of their ancestors. Dressed in brightly coloured clothes, the Setos perform their traditional polyphonic songs, a tradition so prized it's protected by UNESCO. But the Seto culture is under threat as the border with Russia runs directly through their homeland, splitting their community and forcing many Setos to disperse across Estonia. With their numbers dwindling, the future of this small community hangs in the balance.
