The paper introduces a library of video podcasts (vodcasts) used to support the learning and teaching of geographical methods and techniques relating to physical geography and GIScience in particular. While the notion of video learning is not new, the accessibility of the multimedia snippets via lightweight mp4 players in a field context allows a geographical freedom to learning that goes beyond previous classroom-based work. Evaluation, conducted through the use of reflective diaries and focus groups, identified that all students thought the podcast reference library was a valuable learning resource, of particular appeal to students with a visual approach to learning.

This paper proposes a modification to the classic p-median problem that considers the spatial distribution of supply resources and competition for them by potential facility locations. It is illustrated with a simplified case study to optimally locate community scale anaerobic digesters (ADs)

Research reveals that a “finite pool of worry” constrains concern about and action on climate change. Nevertheless, a longitudinal panel survey of 1,858 UK residents, surveyed in April 2019 and June 2020, reveals little evidence for diminishing climate change concern during the COVID-19 pandemic. Further, the sample identifies climate change as a bigger threat than COVID-19. The findings suggest climate change has become an intransigent concern within UK public consciousness.

Vegetation type and cover play an important role in the operation of geomorphological processes by controlling runoff and sediment dynamics. In drylands, land degradation is particularly sensitive to these eco-geomorphic interactions.Whilst many geomorphological studies of land degradation focus on the change in hydrological response as a function of vegetation cover, few have investigated how the autogenic response of plants may influence the susceptibility of soil to erosion through a change of soil resources. This study investigates the hypothesis that shrub communities possess greater soil parameter heterogeneity compared to grasslands, and assesses how these different scales of heterogeneity can influence the susceptibility of soil to erosion.Soil samples were taken from seven 60m x 60m plots within grasslands, shrublands and badlands situated in the Sneeuberg uplands of the central Karoo. 108 samples per plot were analysed for bulk density, organic matter, pH, conductivity and available sodium, calcium, magnesium, potassium and phosphorus. Geostatistical analyses determined that the grassland landscape was largely homogenous in its distribution of soil parameters whereas shrublands demonstrated an increase in heterogeneity. Periodicity in the semi-variograms indicated that regular patterns across the landscape were evident for all parameters and thus likely to represent the differences between shrub and intershrub regions, areas of high and low erodibility. More pronounced patterns were identified in the badlands. This indicates that, if the conditions are right, changes in plant-soil interactions caused by soil parameter redistribution in shrubland landscapes can exacerbate erosion, leading to further degradation in the form of badlands.

This paper reports on reusable mobile digital learning resources designed to assist human geography undergraduate students in exploring the geographies of life in Dublin. Developing active learning that goes beyond data collection to encourage observation and thinking in the field is important. Achieving this in the context of large class sizes presents several challenges. Combining in-situ learning with spatially-accurate historical and contemporary multimedia, we developed a set of location-aware digital mobile tools or 'mediascapes'. We explore how scaffolding can be achieved in such a context, focusing on the development of students' observational, enquiry and thinking skills in the field.
