First vertical farm opens in Singapore

Nine stories of greens.

Channel News Asia's Olivia Siong writes about the opening of what appears to be the world's first commercial vertical farm:

The technique uses aluminium towers that are as tall as nine metres, and vegetables are grown in troughs at multiple levels. The technique utilises space better an advantage for land-scarce Singapore. Sky Greens farm first started working on the prototype in 2009, and has opened a 3.65-hectare farm in Lim Chu Kang.

The farm currently has 120 vertical towers, and hopes to increase the number to 300 by next year. This will increase its current daily supply of vegetables from 0.5 tonnes to two tonnes by 2013.

"The challenge will be to get investors interested. This type of farm needs (relatively) higher capital," said Dr Ngiam Tong Tau, the chairman of Sky Greens. "This is a new system, so people need to be trained (and) we need to attract people to come here to work."

The farm's expansion is expected to cost some S$27 million. Currently, about seven per cent of Singapore's vegetables are grown locally.

The site has a photo of the farm, while more are available at inhabitat:

Vertical farming is of questionable utility at present, but as with so many things, where Singapore goes, the rest of the world may follow. As pressure for locally sourced food squares up against the continued growth of urban populations worldwide, the technology may let off some of that pressure.

Grant Shapps resigns over Tory youth wing bullying scandal

The minister, formerly party chairman, has resigned over allegations of bullying and blackmail made against a Tory activist. 

Grant Shapps, who was a key figure in the Tory general election campaign, has resigned following allegations about a bullying scandal among Conservative activists.

Shapps was formerly party chairman, but was demoted to international development minister after May. His formal statement is expected shortly.

The resignation follows lurid claims about bullying and blackmail among Tory activists. One, Mark Clarke, has been accused of putting pressure on a fellow activist who complained about his behaviour to withdraw the allegation. The complainant, Elliot Johnson, later killed himself.

The junior Treasury minister Robert Halfon also revealed that he had an affair with a young activist after being warned that Clarke planned to blackmail him over the relationship. Former Tory chair Sayeedi Warsi says that she was targeted by Clarke on Twitter, where he tried to portray her as an anti-semite. 

Shapps appointed Mark Clarke to run RoadTrip 2015, where young Tory activists toured key marginals on a bus before the general election. 

Today, the Guardian published an emotional interview with the parents of 21-year-old Elliot Johnson, the activist who killed himself, in which they called for Shapps to consider his position. Ray Johnson also spoke to BBC's Newsnight:


The Johnson family claimed that Shapps and co-chair Andrew Feldman had failed to act on complaints made against Clarke. Feldman says he did not hear of the bullying claims until August. 

Asked about the case at a conference in Malta, David Cameron pointedly refused to offer Shapps his full backing, saying a statement would be released. “I think it is important that on the tragic case that took place that the coroner’s inquiry is allowed to proceed properly," he added. “I feel deeply for his parents, It is an appalling loss to suffer and that is why it is so important there is a proper coroner’s inquiry. In terms of what the Conservative party should do, there should be and there is a proper inquiry that asks all the questions as people come forward. That will take place. It is a tragic loss of a talented young life and it is not something any parent should go through and I feel for them deeply.” 

Mark Clarke denies any wrongdoing.
