Rob Baan (Koppert Cress): vegetables are healthy, but we’re not allowed to claim so
Five years ago, we visited the outstanding horticultural company Koppert Cress in Monster near The Hague in the Netherlands. Then already, general manager Rob Baan told us that horticulture should concentrate on fresh produce for a healthy diet; with ingredients that help overcome diseases like cancer, obesity and diabetes 2. But health claims are supposed
Productive soils as a carbon sink
We know that plants grow faster in CO2-rich environments. Horticulturalists enrich the atmosphere in their greenhouses with CO2 to ensure better productivity. Can we imagine fast growing plants that would capture CO2 from the air, and on a large scale? A carbon sink, as it were? Yes we can, and we can do it in
Indirect effects, we often ignore them
‘Again and again, new products fascinate us: the smartphone, the airplane wing that can be glued, new medicines,’ says Ton Schoot Uiterkamp, ‘but we do not think in terms of chains and generally ignore the indirect effects of these inventions.

Limits to biomass use
Since the turn of the century, there is a discussion raging on the limits to biomass use for energy purposes, in order to control man-made CO2 emissions. After having been greeted with enthusiasm at first, bioenergy is now met with many more restrictions. How do we look upon this after all these years? This is
Club of Rome 50 years old
Fifty years ago, the Club of Rome was founded; in its own words ‘an organisation of individuals who share a common concern for the future of humanity and strive to make a difference….

Healthy soils for a productive bioeconomy
If business site Forbes devotes attention to a subject as esoteric as healthy soils, we know that there will be business in it. As science has discovered the importance of the soil microbiome, this intricate ecosystem of microorganisms around plants’ roots, researchers all over the world start trying to unravel its miraculous properties. Many years
Modern biotechnology: does it develop too fast?
The birth of the hiv-resistant gentech twins Lulu and Nana in China has stirred up the debate on methods and results of modern biotechnology. Rightfully so. The gap between what science can do, and what is ethically responsible in the human domain, is getting too wide. In fact, we even don’t know how to wage
