Together, plants and fungi could slow down climate change
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.…

Common Practice: a livelihood perspective of economic development in the post-Roman world.
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…

Monitoring drought and salinity stress in agriculture by remote sensing for a sustainable future
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,…

Francophone Literature in the Low Countries (1200-1600)
In late medieval and early modern times, books, as well as the people who produced and read (or listened to) them, moved between regions, social circles, and languages with relative ease. Yet, in the multilingual Low Countries, francophone literature was both internationally mobile and firmly rooted…
