Sinking peatlands: Optimal control of subsidence
Abstract Land subsidence threatens the living conditions of about 1.2 billion people worldwide in deltaic regions characterized by soft top soil. Economic activity in these areas requires lowering groundwater levels to keep the land sufficiently dry, which leaves future generations worse off by accelerating subsidence and increasing future costs.

The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Unravelling the evolution of the Frébouge polygenetic cone in Val Ferret (Mont Blanc Massif)
Proglacial settings in the Alps are typically polygenetic, often characterized by a complex and discontinuous interplay between glacial, fluvial and gravitational processes. These processes yield high volumes of sediments, which usually exceed their transportation capacity.
