Emergency adaptation to distance learning: no magic bullet, but where there’s a will, there’s a way

Caroline Pulfrey

Whilst, in many countries, the sudden enforced transfer to large-scale distance learning in state schools as a result of COVID_19 lockdown measures caused turmoil, it also provided an unprecedented opportunity to understand more about key factors associate ...

New perspectives for spatial planning in Switzerland: the role of ecosystem services

Rémi Jaligot

Spatial planning deals with the spatial expression of human activities in an integrated way to minimize their negative impacts on the natural and land systems. Rapid land use and land cover changes are important drivers of change of the benefits people der ...

Tracing China's external driving sources and internal emission hotspots of export-driven PM10 emission

Yue Lu, Qinli Lu

External trade could induce extensive air pollutant emissions among partners. PM10 (particles smaller than 10 mu m) is an important pollutant that could cause various problems. Few studies have researched the spatial heterogeneity of this export-driven pol ...

Model for the erosion onset of a granular bed sheared by a viscous fluid

Matthieu Wyart

We study theoretically the erosion threshold of a granular bed forced by a viscous fluid. We first introduce a model of interacting particles driven on a rough substrate. It predicts a continuous transition at some threshold forcing theta(c), beyond which ...
