Green inspired architects are developing amazing residential, commercial and cultural facilities which are zero-carbon, energy and water efficient. This is the new future.
Het schiet nog niet zo op met circulaire ontwerpen en bouwsels. We hebben in Nederland natuurlijk nog niet zoveel ervaring met het hergebruiken van materialen en nog een andere vraag komt op: hoe kom ik aan bouwmaterialen die ik in mijn ontwerp zou kunnen gebruiken?
Want soms moet je je ontwerp zelfs afstemmen op de materialen die je voorhanden hebt. Dus als je circulair wilt ontwerpen, waar moet je dan allemaal aan denken? Read More
Between the years 1986 and 2006, Toronto experienced not one but eight storms of the magnitude that had been predicted to occur no more than once in a quarter-century. The Finch Avenue Washout was the capper, a one-in-100-years storm for which the city’s infrastructure was woefully under-designed.
The Netherlands is to host a new Global Centre of Excellence on Climate Adaption (GCEA), set up by the Dutch and Japanese governments in collaboration with the UN environment programme (UNEP).
The centre will advise countries, businesses and organizations on how to adapt their practices to comply with the Paris climate change agreement, which comprises measures designed to keep the global temperature increase below 2 degrees.
The University Wageningen concluded that recent cultivation research has led to a reduction of costs of more than 50%. Sustainable seaweed cultivation is necessary to develop new production and market chains!
Let’s introduce to you the SeaFarm: It’s one of the solutions to secure food, feed, green chemistry and energy in the near future.
As per United Nations:
“The world population is predicted to grow to 8.3 billion in 2030 and to 9.1 billion in 2050. By 2030, food demand is predicted to increase by 50% (70% by 2050). The main challenge facing the agricultural sector is not so much growing 70% more food in 40 years, but making 70% more food available on the plate.”
We live at sea
Two third of the world population lives not more than 350 miles from the sea. Somewhat more than halve of the population lives at a maximum of 150 miles from the sea.
In 2050 – in order to feed, clothe, house and energize mankind – we need to have doubled agro production. The big question is ‘Is this possible?’ Yes it is. Which alternatives do we have?
We can speed up deforestation, but then don’t bother about biodiversity, nature etc.
Triple P? Yes, but then bring agriculture to the marine environment. This should be the start of developing sustainable seafarms, based on seaweeds and (shell)fish.
Advantages of a Seafarm
The developed SeaFarm concept and design is a solution to move food production of aquatic and non-aquatic cultures to the ocean surface. Benefits of such solution, comparing to “traditional” farming are:
No land reclamation
Minimizing losses due to pests “infection”
Minimizing or completely removing usage of pesticides
Organic food production is possible without costly and lengthy process of land preparation (“healing”)
Cultures are grown in controlled climate
Cultures are grown in vicinity of the consumers, cutting transportation COx pollution and costs and reducing road congestion
Inserting Oxygen into atmosphere by photo synthesis and reducing CO2
Minimal usage or no usage of fossil fuels or external energy sources
No new or “experimental” technology – only proven components are used
Short “pay-back” period – approx. 18 months for presented case.
This should be the start of developing sustainable seafarms, based on seaweeds and (shell)fish.
According to the University Wageningen, seaweeds-based seafarms produce:
Minerals (especially P)
Starting point for new developments is that it must be TripleP sustainable, since we cannot afford any longer to threaten the worlds ecosystems and its biodiversity, and since we have to meet human requirements such as food security, green chemistry and climate measures.
A futuristic view? We do have 40 years for realization! Seaweed-based sea farming is then an opportunity:
Food security >> proteins, micronutrients and lots of other valuable compounds
Green chemistry >> replacement of fossil resources together with land based plant resources
Energy if not otherwise
Production of fresh water if needed
No freshwater usage for plant production
Recycling of lost plant nutrients
Sequestering Green House Gasses
Off shore cultivation
Logistic, costs of infrastructure yield and planting mechanisms. The University Wageningen concluded that recent cultivation research has led to a reduction of costs of more than 50%. Sustainable seaweed cultivation is necessary to develop new production and market chains!
Seaweed is most commonly recognized as being the green wrapping around your sushi rolls, but it has so much more to offer your body and the planet than just sushi support. Seaweed is known as the ocean’s superfood and is one of the most sustainable, nutritious and cheapest foods we can grow. It’s an abundant source of minerals and has unique cleansing and detoxifying properties. Seaweed is an amazing, underutilized gift straight from the ocean.
Wakame is a wonderful seaweed for women in particular, because it’s been shown to significantly reduce bloating. It tastes a bit like spinach and is commonly used in seaweed salads. Soak it briefly first and keep in mind that it will expand about 20 times. When boiled with water, it provides a healing mineral-rich broth, one that you will find as a base for most miso soups.
Once you get over the slimy texture, you’ll find that seaweed has a lot to offer nutritionally and is easy to sneak into your diet in different forms. Sea vegetables are rich in trace minerals, iodine, iron and calcium. These minerals are essential for proper brain function, metabolism and maintenance of strong bones. They also have powerful electrolytes to help keep you hydrated, contain blood-purifying chlorophyll (remember, they’re still plants and require photosynthesis to develop) and polysaccharides, which detoxify your body from heavy metals and other toxic substances. They can also be great sources of protein, vitamin B-12 and omega-3 fatty acids. These properties definitely qualify seaweed as a superfood — one of the most nutrient-dense foods on the planet.
One of the biggest factors contributing to climate change is the carbon-dioxide emissions produced from factory farming. More than a quarter of the CO2 released into the atmosphere is absorbed directly into the ocean. Seaweed, however, has the amazing ability to absorb dissolved nitrogen, phosphorus and carbon dioxide directly from the sea. It actually needs to absorb CO2 in order to grow, making it the ideal plant to assist with our threatened ecosystems.
We need seaweed to keep our oceans clean. Fortunately, it’s a resilient plant that reproduces quickly. Seaweed farms are becoming more popular and have the capacity to grow nutrient-dense food for both humans and animals. Seaweed also has the potential to be a source of biofuel and fertilizer for crops like corn and soy. As one of the fastest-growing plants in the world, it could nourish the entire planet while leaving a negative carbon footprint — you can think of seaweed as the culinary equivalent to an electric car.
Varieties of Seaweed
Seaweed has more than 10,000 species. It’s very easy to incorporate the most common and easiest species into your diet.

The circular economy represents a viable alternative to this detrimental “linear” model. Rather than going from “cradle to grave,” this new development pathway promotes ‘cradle to cradle‘.
In this type of economy, company growth is no longer reliant on the use of scarce resources.
Instead, it is achieved through the use of disruptive technology and business models that are based on longevity, renewability, reuse, repair, upgrade, refurbishment, capacity sharing, and dematerialization. Read More
Smart urban design requires an integrated look at the city as a complex of material flows and living environment, which exposes the connections between sources, functions, infrastructure and users.
This Research Report ‘Smart Cities’ has been published by the University Delft. The researchers consider Smart Cities as a way of working on a future-proof city, cleverly making use of people, resources and systems.
In this Delft Smart City research project, students examined the possible impact of recent developments under the heading ‘Smart City’ for Delft.
The challenge we face is big, perhaps bigger than many people imagine. But so is the opportunity. If the world can find a source of cheap, clean energy, it will do more than halt climate change. It will transform the lives of millions of the poorest families.
