The government of Uruguay has launched ambitious plans to make hydrogen and green fuels.

The country generates far more of its electricity from renewables than most countries - Uruguay produces more than 90% of its electricity from sustainable resources, like wind. And that, the government says, puts it in a good position to start producing green hydrogen.

Proponents of green hydrogen production in Uruguay say it will be good for the planet and the country's economy, but could it use too much water?

Andy Yen is founder and CEO of tech company Proton, best known for its encrypted email service Proton Mail.

He was born in Taiwan, studied in California, then moved to Switzerland to work at CERN as a particle physicist. He then set up Proton from Geneva.

Dougal Shaw talks to the entrepreneur about growing up in the shadow of China, personal privacy in an age when we live our lives online, and his company’s “cat and mouse” games with Russia over VPN software, which allows people to access the internet without state control.

Wary of the perceived threat from Russia, the countries that make up the Nato Western military alliance are upping their spending on the military. But not fast enough, according to former US president Donald Trump, who has made the issue part of his election campaign.

So should governments in Europe be spending more on their collective defence? Do Europeans want them to, or would they rather that money go to things like education and healthcare instead?

As Sweden joins the alliance, we look at who is spending what within Nato, who is pulling their weight, and who is not.

We speak to people across Europe about what they want, and we talk to one former army chief, who says his country is woefully underprepared to defend itself.

We trace the commodity’s journey from sugar cane farm, to mill, to candy shop, all in a quest to find out why the cost of sugar has gone up. The US is the world's fifth largest sugar producer, with sugarcane grown in the south and sugar beets in the north. Even though the cost of sugar is rising worldwide, Americans pay twice as much as the global average for sugar because of a government policy. Brought about to protect domestic producers, a protectionist policy taxing imports of sugar is actually creating higher prices, a report by the government accountability office found in October.

We travel from a candy story in New York, to a sugarcane farm and mill in Louisiana, to find out what the impact will be.

There's been a wave of farmers' protests across Europe in recent weeks.

France, Germany, the Netherlands, Spain and Eastern European countries have all seen farmers airing their grievances by driving their tractors into towns and cities and blocking roads.

There have also been similar demonstrations far beyond Europe, in India.

Guy Hedgecoe has been looking at the protests and how some grievances are uniting farmers from different countries while others are dividing them.

Because farming is so important for our day-to-day lives, the outcome could affect us all.

Last summer marked the first time in six decades that Hollywood’s actors and writers went on strike simultaneously. They hit pause on production over pay and the use of artificial intelligence (AI) in the film industry.

The strikes brought the industry to boiling point, but wider issues were simmering for some time.

They caused a multi-billion economic toll on those who work in film and television - from crew members to caterers. Businesses burned through savings and piled up debt.

This edition of Business Daily unpicks the plot of one of Hollywood's biggest dramas.

The important shipping route runs for 82 km through Central America, connecting the Atlantic and Pacific Oceans.

But a long period of dry weather means the water in the canal is very low, reducing the number of boats that can travel though.

We travel to Panama to look at the impact this is having on shipping companies, manufacturers and consumers, and find out what the Panama Shipping Company is trying to do about it.

Up to 10% of areas for major crops and livestock could be rendered unsuitable by climate change by 2050, so what can farmers do to adapt to rising temperatures and extreme weather events?

Stefania Gozzer meets a farmer in Spain to see how severe droughts ruined his cereal harvest, and she pays a visit to his neighbour, who has managed to grow tomatoes without watering his fields.

Global warming poses huge challenges for agriculture around the world - and various ways of managing its effects are now being practised by farmers. Among them is planting trees next to crops. We hear how this technique changed the life of a Kenyan farmer.
