Abstract: Moving agriculture into the highlands of the Tibetan Plateau, was a challenging process. Short growing seasons, cold winters and spring frost mean that the Tibetan plateau presented considerable challenges to the movement of domesticates into this region. In this paper, we describe the creation and employment of crop niche models aimed at outlining the constraints associated with practicing a range of different crops on the Tibetan plateau and in the foothills of the Himalayas. These models contribute to explaining a profound change in both settlement patterns and in subsistence regimes on the Eastern Tibetan Plateau when a shift from a millet-based agriculture to wheat and barley based agro-pastoralism took place c. 2000 cal. BC. Using a model that predicts the changing distribution of crop niches across the area, we examine the role that changes in ancient climate could have played in the reversal of subsistence practices in this area.

"Waves and Mean Flows (and Math) on Reefs"

Sea-level rise and storm activity threaten the habitability of low-lying reef fringed islands and atolls.  Statistical analyses of observations of waves and mean flows on reefs during energetic storms reveal patterns amenable to simple, robust mathematical descriptions.  These simple models are used to predict extreme shoreline water levels, to inform projections of flooding under future climate scenarios, and to form the basis for early warning systems.
