One of the biggest challenges facing the nuclear industry today is how to deal with the lethal radioactive waste which has accumulated over decades. Governments across the world are trying to find a permanent solution to keep the waste safe and secure. Presenter Theo Leggett visits Sweden, where progress is being made with deep geological storage. Maria Fornander from Sweden’s nuclear operator SKB, explains how the waste is initially placed under water, and will then be buried in cast iron 500m underground. Theo visits the Äspö Hard Rock laboratory, where SKB project director Ylva Stenqvist is testing the techniques and equipment. Rolf Persson of the Oskarshamn Municipality, says other countries planning similar ventures could learn from Sweden’s approach. Neil Hiatt, the chief scientific adviser to the UK’s waste management group Nuclear Waste Services, speaks to Theo in Sweden - how might it work in practice? In the UK, similar proposals have faced local opposition, Marianne Birkby runs a pressure group, Radiation Free Lakeland, opposing a possible waste facility in the North of England. And Dr Paul Dorfman, from the University of Sussex, explains why he believes plans for geological disposal are at best premature – and potentially impossible to deliver safely.

It's been six months since the Russian invasion of Ukraine. According to the UN Refugee Agency UNHCR, the war in Ukraine has pushed the number of refugees across the world to more than 100 million. In this programme we hear from refugees about starting a new life - and a new business. Yuliia is from Ukraine but is now living in England. On the day she fled her home country, she threw some belongings in a bag, took her two children and drove across Europe. She was a wedding dress designer in Ukraine and is now hoping to restart her business in the UK. Razia works for Silai Wali - a social enterprise led by Afghan-women refugees in New Delhi. It up-cycles waste fabric to create handcrafted decorations. Plus, Bish Wadeep Mortia who set up the company, tells us more about how it works. And Waseem is from Jumpstart Refugee Talent in Canada - it is a refugee-led non-profit organisation whose sole purpose is to help people find work or start new businesses.

Six months into the war in Ukraine, the impact continues to be felt around the world. Frey Lindsay explores how disruptive the war has been for agriculture across Europe. Researcher Roxana Barbalescu explains just how vital Ukrainian workers are to the farmers and producers of Western Europe, and the problems their absence is creating this season. We hear from farmers in Poland and the UK on the economic, and emotional, impact of their former colleagues taking up arms to defend their country. At the same time, the war has had a major impact on Ukraine’s own agricultural production and exports. Markiyan Dmytrasevych, Ukraine’s deputy agriculture minister, tells Frey what the government are doing to try and keep Ukrainian farmers afloat. And we hear from Lubomyr, a former seasonal worker who is back in Ukraine and has his own unique plan for helping to sustain agriculture in his country.

It's been six months since Russia invaded its neighbour Ukraine. In the early days, in late February, March and April, charities were overwhelmed by donations and offers from people who wanted to help. But they're now having to work much harder to get much needed donations.

Ukrainian chef and author Olia Hercules is finding new ways to fundraise for families left behind in her home town. When war broke out Olia told the BBC's Victoria Craig about getting money and vital equipment to her brother on the front line. We catch up with Olia in her London home.

Ronny Krieger, general manager of Patreon Europe, explains how people looking to raise money are using the fundraising platform.

We also hear from Ukraine-based charity Aid Legion. Its co-founder Anna Goncharova tells us how she and her colleagues worked to come up with a campaign to rally people to the cause in an uplifting, impassioned way.

With a population of just over 50,000 people the Faroe Islands are spending vast sums of money digging sub-sea tunnels to keep remote communities alive. Combined with a government subsidised helicopter service, it allows islands with a handful of permanent inhabitants to thrive and has helped reverse the trend for young Faroe Islanders to emigrate in search of a more modern lifestyle.

Join Tim Ecott, author of The Land of Maybe: a Faroe Islands Year, as he flies over this remote North Atlantic archipelago and ventures deep beneath the ocean to investigate why big spending on infrastructure brings huge social benefits to the islands.

We look at Japan’s bid to compete with Silicon Valley. Japan is well known for innovations such as the walkman, bullet trains and Nintendo games, but the country hasn’t produced a killer product to really wow the world for decades. The government wants to change that by increasing the number of start-ups by ten-fold over the next five years. In this episode Mariko Oi travels across her home country to meet with the next generation of entrepreneurs hoping to make Japan Asia’s Silicon Valley. She hears from Chikahiro Terada, the boss of Tokyo-based start-up Sansan, which specialises in the digitalisation of business cards. Chikahiro is opening a special new school for tech-savvy young entrepreneurs in Tokushima on the southern island of Shikoku. Mariko also meets the founder of a mobile supermarket business and speaks to the country's former digital minister, Karen Makishima, who says there will be fewer rules for digital start up companies and that the government will be encouraging more diverse entrepreneurs to set up businesses in rural as well as urban areas.

It might seem like a step forward when advertisers want to appeal to a historically marginalised community, but the use of the LGBT rainbow flag by companies and organisations has become a bone of contention.

If an investment company changes its logo to a rainbow background is that a genuine attempt to support LGBT rights, or a cynical marketing ploy? In short, is it rainbow washing?

Jamie Love, marketing director of Edinburgh Pride tells us how potential event sponsors are vetted, plus Leticia King James who’s the vice president of diversity inclusion and belonging at logistics giant GXO explains why her company is sponsoring small, regional Pride events.

We also hear from Kathy Caton, founder of Brighton Gin who explains why a 365 day commitment to diversity is vital for companies marketing to the LGBT community. Julia Smith-Eppsteiner, a senior strategist at branding company Future Brand explains how accusations of rainbow washing can be avoided and Paul Thompson, co-owner of LGBT Capital explains just how lucrative the LGBT market is.

Victoria Craig whisks us off to the Greek island of Tinos to find out about a Greek government strategy to prevent over-tourism.

On this virtual vacation, you'll meet an artisan cheesemaker, some travellers, and a restaurant owner to find out whether the government strategy to promote travel to less well known destinations is working, or even welcomed. There are concerns the strategy could erode traditional ways of life on the Greek islands and in the Greek villages tourists don't often reach.

New forms of electric transport are revolutionising the way we travel for both work and leisure.

Soaring gas prices around the world are encouraging people to look for alternatives such as electric bikes, kick scooters and mopeds.

Tara Holmes visits a new bike shop in the Peak District in England, and speaks to husband and wife team, Richard and Madeline Bowker, owners of Criterium Cycles, and gets the chance to try out one of their best-selling e-bikes. The global market for e-bikes today is worth $35billion.

Professor David Greenwood, an electrification expert at Warwick University in the UK, offers some tips on how to avoid buying unsafe vehicles.

And, Augustin Friedel, an independent analyst and mobility expert from Germany reveals which countries are most encouraging new forms of electric transport and how this is being done safely.

We also hear from Iñaki Uriz, the chief executive of Caravelo, a subscription platform for the airline industry on travel trends.
