Natural multi-hazard risk perception and educational insights among Geography and Tourism students and graduates amid the Covid-19 pandemic.

Multi-hazard risk perception is an emerging research topic that has been gaining more and more interest since the beginning of the Covid-19 pandemic, due to the unprecedented interactions between the management practices of the pandemic and of other co-occurring natural hazards, and to the compounded impact of these multi-hazards. This paper aims to investigate the specialization and study level-dependent differences concerning multi-hazard risk perception and hazard-related education insights of future potential specialists in natural hazard-induced risk management and tourism reconstruction. These differences were explored by applying a multi-layer questionnaire on 547 Geography and Tourism students and graduates from two universities in Iași City (Romania) and Novi Sad (Serbia), and performing descriptive and differential statistical analyses.

Climate overrides fencing and soil mineral nutrients to affect plant diversity and biomass of alpine grasslands across North Tibet.

Introduction: Overgrazing and warming are thought to be responsible for the loss of species diversity, declined ecosystem productivity and soil nutrient availability of degraded grasslands on the Tibetan Plateau. Mineral elements in soils critically regulate plant individual's growth, performance, reproduction, and survival. However, it is still unclear whether plant species diversity and biomass production can be improved indirectly via the recovery of mineral element availability at topsoils of degraded grasslands, via grazing exclusion by fencing for years.

Disentangling climatic and anthropogenic contributions to nonlinear dynamics of alpine grassland productivity on the Qinghai-Tibetan Plateau.

Alpine grasslands on the Qinghai-Tibetan Plateau are sensitive and vulnerable to climate change and human activities. Climate warming and overgrazing have already caused degradation in a large fraction of alpine grasslands on this plateau. However, it remains unclear how human activities (mainly livestock grazing) regulates vegetation dynamics under climate change.

Using archaeological and geomorphological evidence for the establishment of a relative chronology and evolution pattern for Holocene landslides.

Hilly regions around the world are one of the most vulnerable places for inhabitation, where landslides represent a permanent threat for their population. In some particular cases, in the past, due to their topographic features, areas affected by massive landslides served a real opportunity for the location of strategic and fortified settlements. In this study, we have extended a previous approach of correlation between landslides and archaeological heritage, adding 14 new representative case studies of landslided hillforts, a new period with landslided hillforts, and a new typology of relationship (landslided tumuli) for establishing relative chronologies for landslide inventories.
