A key road which has been closed for four days after a water main burst has now reopened, a water company has said.

Drivers reported "chaos" in Gloucester after the A417 Over Causeway shut outbound at 19:00 BST on Friday, between Alney Island and Over Roundabout.

Severn Trent said it had been working "through the night" to fix the road surface after repairs were made to the burst water pipe.

The city was gridlocked on Saturday with cars reporting being stuck in traffic "for hours" and one resident said getting out of his house was "torture."

In a Q&A on its website, Severn Trent said it received a report of a small leak in the road earlier last week, and scheduled a repair for Friday evening to minimise disruption. But the leak got "considerably worse".

"We did manage to fix the burst and stop the flow of water, but a lot of damage has been caused to the carriageway, meaning it wasn't safe for cars or our workers," it said.

The world's rainforests are often referred to as the "lungs of the earth".

They store billions of tonnes of carbon and in doing so help to reduce the impacts of climate change.

But with more than one and half trillion trees, measuring exactly how much carbon they store has been virtually impossible, until now.

On Tuesday, the European Space Agency (ESA) successfully launched a first-of-a-kind satellite which uses a special radar system to reveal what lies beneath the canopy.

It is hoped it will help scientists better understand the importance of rainforests in storing carbon and the impact of deforestation.

Hoarding disorder has become "a national emergency in America", an MP has said, "so we need to look at it here."

Paulette Hamilton, Labour MP for Birmingham Erdington, spent years as a district nurse before entering politics.

On her care rounds she would sometimes encounter patients living in hoarded homes, where their mental health had deteriorated to such an extent that they were surrounding themselves in personal possessions.

"You can't just go in and clear a house and that's what people need to understand," Hamilton said.

"As a society we have a responsibility to support them, and Heather has shown us the way".

The MP is referring to Heather Matuozzo, founder of Birmingham-based social enterprise Clouds End CIC, whose work in communities the BBC has been following for four months.

As well as offering hoarding training to professionals nationally, her group has supported more than 300 people in Birmingham who hoard or are at risk of hoarding.

It offers people help to declutter their homes while also ensuring they have access to the appropriate mental health support.

In a recent meeting in Westminster, Ms Matuozzo informed the MP that the numbers needing support in the city – and those being referred for help – had risen exponentially since the Covid pandemic, something which was likely to have been reflected across the country.

Earlier estimates suggested that between 2-5% of the population experienced hoarding disorder, a condition recognised by the World Health Organisation in 2018, but those with direct experience of home visits – including charities and psychologists – said the true figure was far higher, with potentially up to six million people affected in the UK.

"It needs to be a little more joined up, government, the NHS, so it's not just the voluntary sector and others that are trying to cure it," Hamilton said.

She agreed with Ms Matuozzo that new national guidelines may be needed to address a significant increase in people who hoard in the UK.

Hamilton said she planned to bring the issue up with the health and social care select committee, of which she is vice chair, "and from this we could have some very strong recommendations which we can take to the Department of Health to get into communities".

While individual local authorities such as Birmingham City Council have developed strategies to support hoarders in recent years, there are no national guidelines or single government policy which addresses hoarding directly, something psychologists have been continually pressing for.

Similarly, while NHS Integrated Care Boards manage funding for a range of mental health conditions in communities, there are no specific funding streams for hoarding, leaving voluntary groups to provide outreach work in most cases.

"A new approach must be based in empathy and compassion and putting people at the heart of these difficulties first", said Sam Wainman, from the University of Birmingham's school of psychology.

"I'm continually surprised by how much of a lack of awareness there is among professionals or wider institutions. There is not enough support out there."

Ms Matuozzo said this was now the opportunity for the UK to prepare its response.

She said: "I've come away from Westminster with a feeling of enthusiasm. It's the first step and it's not going to be overnight to change things, but neither has my whole journey to this point."
