Jan de Vetten brengt zijn promotieonderzoek ook uit in boekvorm. ‘In de ban van goed en fout’ beschrijft voor het eerst - op basis van archiefonderzoek en interviews - op samenhangende wijze de bestrijding van de CP en CD, en ook de reactie daarop van die partijen. Waarom werden ze zo fel werden bestreden?…

A special relationship between plants and fungi, which plays an important role in carbon storage in soil, has the potential to slow down climate change. However, the amount of carbon stored in soil is decreasing as a result of human activity. This is what researchers say in a publication in Nature Communications.…

What are the key issues in conducting LCA of bioenergy systems? What is the environmental sustainability status of second generation bioethanol? How much would the final results of biogenic carbon neutrality assumptions deviate from the true values based on a complete inventory? How to assess the impact…

How can we quantify the density of species within a community through environmental DNA concentrations?

Today’s socio-economic challenges aren’t new. In the centuries after the retreat of the Roman state people with different backgrounds and with different ways of life somehow managed to build and maintain a complex economic system in northern Gaul that would produce the ruling dynasties of Europe. By…

Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…
