Floating bridge in Angkor Wat, Cambodia near completion

A temporary floating bridge is being constructed in Angkor Wat, Cambodia, that will allow local visitors and tourists to continue visiting the famous temple while reconstruction work on the original bridge gets underway. The repairs require total closure of the original Spean Harl bridge so that experts from APSARA Authority and Sophia University can restore it.

The floating bridge is nearly 200 metres long and 10 meters wide and will be able to support a total of over 6000 people at any given time. Made of polyethylene airbags, the material is strong enough to withstand use for up to 20 years. The plastic bridge will have six viewing areas where visitors can stop to take photographs and admire the ancient temple and should be ready for use before May.

Blue21 article ‘Potential of Floating Production for delta and coastal cities’ published by Elsevier

We are very proud to announce that our article “Potential of Floating Production for delta and coastal cities” was accepted for publication on Elsevier’s Journal of Cleaner Production.

The article presents the results of our research on the BlueRevolution potential for cities. Water space nearby cities provides an opportunity for closing cities resource cycles and accelerating the transition to a bio-based economy. Reusing waste nutrients and carbon dioxide available in cities, biofuel and food can be produced on water through algae and aquaponic systems. The direct effects on local resiliency and the role of floating production in global land shortage reduction are discussed for two case studies, Rotterdam and Metro Manila. The publishers version is available on ScienceDirect and you can find the full manuscript on our website now.

Global Centre of Excellence on Climate Adaptation to reside in the Netherlands

On the 6th of February 2017 the Dutch Ministry of Infrastructure and Environment signed a Statement of Intent, together with global partners, which marks the start of the Global Centre of Excellence on Climate Adaptation. The Centre will address the challenges faced when dealing with climate change adaptation issues. The initiative will be led by the Netherlands, Japan and UN Environment.

The ground-breaking Paris Climate Change Agreement has made climate change adaptation a global priority. By supporting those that struggle with climate change adaptation and developing a pool of global knowledge on the subject, The Centre of Excellence on Climate Adaptation hopes to contribute to the resilience of our planet whilst helping others that are dealing with issues such as natural disasters and economic disruptions.

Massive photovoltaic power station built on fishery in China now operational

In Cixi City in the Zhejiang Province in eastern China a solar power station with a 200 MegaWatt capacity has been installed above a fish farm. China’s largest photovoltaic (PV) solar farm consists of 300 hectares of solar panels that can generate enough power for 100.000 households. By connecting the power station to the national grid, the fishery can expected an annual yield of 240 million RMB (US$34M) above the annual income already generated through the fish farm.

The solar panels have intentionally been spaced far enough apart in order to let sunlight penetrate the water so not to disturb the growth of the fish beneath the surface. In addition the PV panels installed above the pond will provide shade that will facilitate fish farming under the water. The renewable energy concept might just inspire other fisheries to follow this example.

As Climate Change Accelerates, Floating Cities Look Like Less of a Pipe Dream

That was the headline in the New York Times last week when the news broke about The Seasteading Institute’s plans to develop the first floating city in the waters of French Polynesia. The project has gained extensive international attention with prominent (online) newspapers covering the story such as The Daily Mail Online, The Dutch Cowboys and De Tijd.

To date, The Seasteading Institute has raised around $ 2.5 million from more than 1.000 investors to take the first steps in realising a seastead in a lagoon off the island of Tahiti. It is estimated that a total of between US $10 million and US $50 million will be needed to realise this ambitious plan.

The floating city will consist of 16 platforms made from reinforced concrete that will be strong enough to support three-storey buildings such as appartments, hotels and offices. Blue21 has been collaborating with The Seasteading Institute on the design of the sustainable modular platforms which will enable inhabitants to rearrange them according to their needs. Over the coming months Blue21 will continue collaborating with the Seasteading Institute to finalize the design of the floating city and the plans for development. Construction should start by 2019.

Where privately funded organisation such as The Seasteading Institute have clear ideas on how to overcome the challanges that climate change bring us, governments seem to be less focussed on battling these dangers. In the run-up to the upcoming elections in The Netherlands the national newspaper Trouw looked into the plans running political parties have for taking a stand in climate change. Unfortunately none of the parties seem to have a clear strategy on how to proceed. Let’s hope that the government will be inspired by the historical deal made in French Polynesia and take concrete steps against climate change in other parts of the world.
