Even plants can have neighbour trouble
Restoring a natural plant environment on exhausted agricultural lands and in nature areas is difficult. We can speed this up by steering the soils towards the desired situation. This is what Martijn Bezemer, newly appointed Professor of Ecology of Plant-Microbe-Insect interactions at Leiden University’s…

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,…
