Raising Diemen: Amsterdam's never ending battle against the sea

Amsterdam is a city that is constantly sinking into the North Sea, and being dragged out again by its determined citizens. Built on layers of overworked peat, overwrought clay and the overly intrusive North Sea, this capital city is a subsiding monument to Dutch engineering.

The silver-lining to all this sinking is that Amsterdam council has found a number of ways to link raising the city to citizen wellbeing. It’s not just about raising the streets to their previous levels: it’s about improving the lives of people who live on those streets.

The technology used to do this was on offer to – and robustly ignored by – both the US and UK governments, prior to Hurricane Katrina and the UK floods in 2014. But that may have to change: the cities that will be underwater if we embrace all the hubris and melt all the ice by burning all available fossil fuels include London, New York and Hong Kong.


The latest terrifying numbers on climate change include the news that the heat waves which used to happen every three years are now happening every 200 days. With these doom-laden figures in mind, and the uneasy knowledge that my Amsterdam apartment is 5.5m below sea-level, I went to find out exactly what it means to raise a city.

Maita Van Der Mark is an alderman for Diemen: a small town in the south of the Amsterdam-area, surrounded and intersected by multiple rivers. Areas of north Diemen are currently being raised back to their previous levels.

The project saw used satellite technology to pinpoint exactly which areas of the city are sinking, and when work will need to begin. Armed with this information, civil servants started redesigning Diemen; they then sorted through citizen feedback, and checked in with the town council, before presenting the plan to the alderman and the mayor.

Van Der Mark is involved in the community outreach side of things: her job is to ensure the citizen satisfaction levels are rising along with the pavements.

Since 2012, the aldermen have been working to citizen wellbeing targets: Van Der Mark herself is responsible for making sure the public are aware of when, why and how their neighbourhoods will be reconfigured.

“We took [the 2012 targets] as an opportunity to look at the needs of the community,” she tells me. “The town council wanted a more harmonious public space, and that naturally lead to more citizens participating the in the redesign.”

The sinking is caused by the ancient peat and clay beneath Diemen slowly compressing into thinner and thinner layers. The maximum amount an area can be allowed to sink by is 20cm: at that point, cracks are appearing in the pavements and street signs are starting to look rather inebriated. (Some of the buildings are sinking too, but not as quickly: they usually have stronger foundations, rather than just sitting on top of slowly condensing peat and clay. These also aren't being raised in this particular piece of work.)

The raising is accomplished by, affectively, lifting up the sinking area, adding another layer of sand and soil, and then laying the pavements, tarmac, playgrounds, et al. back down again. The rate at which neighbourhoods are sinking can vary: some areas need work every five years, others only once every 50. But after the first few hundred years of doing this, the Dutch had streamlined the process so effectively that entire neighbourhoods would be raised with minimum disruption.

Before the aldermen began doing citizen outreach, many Amsterdam-area residents wouldn’t have been aware that their streets were being raised at all.

“Last time I saw the workmen but I didn’t really ask what they were doing,” explains Anita, a Diemen resident. “The builders were here for a few days and then they left and the streets were nice. We got a note saying we needed to raise the garden and that was that. We raised it. This time they [the town council] have explained what’s happening and invited us to meetings about it.”

This increase in communication doesn’t only mean that citizens are more involved with the planning process: it’s an opportunity to air some neighbourhood disputes and dissatisfaction with the previous attempts at town planning. This has included ongoing discussions about where a children’s playground should be relocated, and whose turn it is to have the street’s trees in front of their house.

The raising and redesigning of Diemen’s streets is easy to spot. A street paved with bright white stones suddenly disappears into a privately owned path composed of cracked, discoloured slabs. Privately owned property must be raised by the owners: often between 10 and 20 houses will be involved in discussing the costs, and it can take another year for a homeowner to organise for their own garden to meet the newly raised street.

None of which acts as a deterrent for house buyers or investors: the raising process has become such a part of life residents like Anita didn’t even consider potential building work when buying property in the area.

There is a misplaced perception that adapting cities to climate change is a massive, costly headache: this is usually the reason given by governments for not taking advantage of the Dutch anti-flood technology. When one looks at the raising process in Amsterdam, however, it’s clear that reconfiguring a city (or even a few postcodes) can be a positive, low-impact undertaking.

Despite politicians’ reluctance to face reality, the effects of climate change are already being felt around the world. As more of our capital cities are threatened, it’s going to become increasingly difficult for governments to hide from the Dutch technology – or their pragmatic approach to citizen wellbeing.

 
 
 
 

The future is here: Register now for Barcelona’s New Economy Week

Barcelona New Economy Week (BNEW) starts this Tuesday with the goal of turning the Catalan city into the "global capital of the new economy".

BNEW runs from 6 to 9 October, with registration remaining open throughout the event, offering insight from 350 speakers on how businesses can bounce back from the impact of the coronavirus pandemic. It will feature top speakers from the business sectors of real estate, logistics, digital industry, e-commerce and economic zones.

The hybrid, business-to-business event – which is taking place in physical and virtual forms – is organised by Consorci de la Zona Franca (CZFB) and will showcase the way in which Barcelona is preparing for the post-Covid world and the "new economy". It is the city’s first big business event of the year and aims to help revitalise and restart the local economy.

“BNEW will be the first great event for the economy’s global recovery that will allow the redesigning of the productive fabric,” says Pere Navarro, state special delegate at CZFB. “It is an honour to have the participation of renowned professionals and attendees from all around the world.

“As we are not in a position to do a proper ‘in person’ fair, we decided to adapt by creating a disruptive and useful event in this way to relaunch the economy.”

The conference will encompass five interconnected events incorporating real estate, logistics, digital industry, e-commerce and economic zones. More than 8,000 professionals from 91 countries from all over the globe will take part virtually. A further 1,000 delegates are expected to attend the five events in person. Over 200 speakers will take part physically, while the rest will give their talks via a digital platform especially created for the unique event. An advanced digital networking platform – using artificial intelligence – will cross-reference the data of all those registered to offer a large number of contacts and directly connect supply with demand.

The conference will also be simultaneously broadcast in high-quality streaming on six channels, one for each of the five interconnected events and an additional stream showcasing Barcelona’s culture and gastronomy.

BNEW will take place in three venues in the city: Estació de França, Casa Seat and Movistar Centre. All are open, digital spaces committed to the United Nations’ 2030 Agenda. Estació de França will host the BNEW Logistics, BNEW E-commerce and BNEW Real Estate events, while Casa Seat will be home to the BNEW Economic Zones event, and the Movistar Centre will host the BNEW Digital Industry.


Some 36 companies are sponsoring BNEW, and 52 start-up companies will take part and present their highly innovative products and services. A further 128 firms will participate in BVillage, a kind of virtual stand where they can show their products and schedule meetings with potential clients.

Highlight sessions will include: "the era of humankind toward the fifth industrial revolution," by Marc Vidal, a digital transformation expert; "rational optimism," by Luca Lazzarini, a commercial communications specialist; and "future smart cities’ challenges and opportunities," by Alicia Asín, a leading voice on artificial intelligence. Sandra Pina will also talk about how sustainability is transforming us, Jorge Alonso on the humane future of cities and Pilar Jericó on how to face changes in the post-Covid era.

BNEW is described as a new way of developing your know-how, expanding your networks and promoting innovation and talent.

“Networking is always one of the main attractions of the events, so to carry it out in this innovative way at BNEW – with the high international profile it boasts – is a great opportunity for companies,” says Blanca Sorigué, managing director of CZFB.
