Do you want to catch up on the UN sustainable development goals, sustainable floating communities and impact investing? You can. Our BlueAcademy on these topics was live streamed, with investment experts and water pioneers from all over the world.
We were especially honoured to host our guest from the Bay Area, Ari Eisenstat. He is the founder of Draemventures, an impact investor and an International Chamber of Commerce representative for the United Nations.
Check out the two live streams Ari Eisenstat posted via Facebook (and do yourself a favour and strike the Power Pose, instructions in the second live stream!).
Today we will host a last minute BlueAcademy on water pioneering, impact producing, social entrepreneurship and start ups, together with our guest Ari Eisenstat. Ari is the founder of Draemventures and an International Chamber of Commerce representative for the United Nations.

Are you a socially, technically or environmentally conscious start up?
What does the blue revolution mean to you? And what could you do to accelerate it? We talk about these questions on a daily basis, but last week we invited our expert network of water pioneers to brainstorm together with us – in real life.
Together we came up with multiple ideas – varying from rethinking our own eco-system to building a proof of concept in the Netherlands. Also, several challenges were identified, like current legislation, being the first to take the risk and people’s perception towards floating and towards change.
Opportunities predominated the brainstorm though. Like how floating development can offer low costs solutions for the urban poor and stimulate the local economy of land-based cities. For example by creating short stay floating co-work spaces, eco tourism facilities and inspiring icons to celebrate the history of crazy-Dutch-water-engineering.
So what’s next? We all can’t wait to work out a business case on a floating development project we can work on together – with as much (international) water pioneers as possible. This will be the subject of our next brainstorm so we will keep you posted.
In the meantime, if you have a great idea to accelerate the blue revolution, feel free to leave us a message. Or get inspired first by this video-message by Joe Quirk, Communications Director at Seasteading and aquapreneur at heart, who thinks we should build a floating Venice of the Dutch…(!)
The battle against climate change will be a race against the clock. Engineers will have to fight on two fronts. The first front is the transition towards a sustainable energy system. The second front is the protection of the population against sea level rise, floods, droughts and heat waves.
Wake-up calls Climate change is happening right now and at a frightening speed, especially in the Arctic. To underpin the need for action, I share three wake-up calls:
The Arctic is melting

Temperature records are broken all over the world

Engineers in the forefront We can’t afford to ignore the warning signs. The longer we wait, the harder it will be to get climate change under control. After long negotiations, world leaders have agreed on action at the Paris climate summit. Now it’s up to the engineers to develop ambitious plans and innovative solutions.
Towards 100% sustainable energy In theory, the area of all solar panels that are needed to power the world is a small percentage of the surface of the earth. In reality, where humans live, the earth is already covered with farmland, houses and industries. Furthermore, solar energy must either be stored during the night, or be supplemented by other energy sources.
We need to find more places to host solar panels, wind-farms and biomass production plants. Increasingly, reservoirs, seas and oceans are regarded as the place to be.
“Water systems will play a vital role in the production of sustainable energy”
Many reservoirs in rivers are already in use for hydro-power production and the temporary storage of excess energy. Offshore wind turbines produce electricity for coastal cities. The rough conditions at sea require a robust design of the constructions. Floating wind-farms are the latest development in the offshore wind industry.

Yet there is more to explore at sea, such as tidal energy, wave energy and biomass production. Seaweeds and algae grow on solar energy and consume the greenhouse gas CO2. A good combination, as Blue21 indicated in their call for action. The seaweeds and algae can be used to produce biofuels, chemicals and food.
Let’s think big about the opportunities at sea. The combination of seaweed farms with wind-farms, former oil platforms and industrial facilities might be very effective. At such an offshore energy plant, biomass can be processed and energy stored, before it is transported to the shore.

Adaptation to climate change Even if we could switch to 100% sustainable energy overnight, the climate will continue to change, due to past emissions of greenhouse gases. Sea levels will rise, and the frequency of floods, droughts and heat waves will increase.
Engineers can design technical solutions to these problems. Coastal cities can build dikes and structures to prevent flooding. Nowadays, smart dikes are equipped with sensors that give continuous feedback on the actual state of the dike.
“Investments in flood defences for an uncertain future must be well-founded”
In delta areas, there is a complex combination of factors at play. Sea level rise and land subsidence, floods and droughts, urbanisation and technological progress account for an uncertain future.
Adaptive delta planning is a new method to design a roadmap to the future. The roadmap shows the signposts that trigger policy actions. The improvement of a flood defence system will be triggered when sea level, land subsidence or population growth exceed a certain threshold.

Conclusion Climate scientists have been warning us for decades. The Paris climate agreement made clear that the political leaders are ready for action. More than ever, engineers will have to show what they are capable of and develop sustainable solutions. Climate change is the challenge of our generation.

Creating places and the settling of communities on the earth’s surface is an ancient, primordial activity that reinvents itself constantly. Ever since people started to build permanent settlements for habitation, they (re)arrange the physical structure of communities around the numerous activities that make up their daily lives.
