This review paper compiles research related to debris flows and hyperconcentrated in the central Andes (30°–33° S), updating knowledge of these phenomena this semiarid region. Continuous records are lacking through Andean region; intense precipitations, sudden snowmelt, increased temperatures on high relief mountain areas, permafrost degradation violent flow discharges. Documented catastrophic ...

[1] Dozens of large, low‐gradient alluvial fans are present within impact crater basins on the cratered highlands of Mars. The timescales and climate conditions that were required to generate such fans are unknown, but testable through our understanding of terrestrial hill slope erosion in the presence of precipitation. Previous estimates of fan formation time vary from years to millions of yea...

In West Africa, the most extreme predicted effects of climate change are expected to occur in desert and grassland areas. It is crucial for local populations in this region to better understand what such projections signify to them to identify sound adaptation policies and interventions. We developed a game, called the “grazing game,” and conducted trials with local farmers at multiple study si...
