“…There is a need to communicate the research results and their quality with appropriate explanations for the local officials, environmental managers and the public to raise awareness and knowledge about it, which leads to an easier understanding and incorporation of the results into the decisionmaking process (Knuepfer and Petersen, 2002;Rogers, 2006;Brierley, 2009;Hill et al, 2013). This analysis might aid good acceptance of the landslide susceptibility maps in the local governments, as instead of a fuzzy statement on involved uncertainties, these are clearly shown in a map on grid cell level (Guzzetti et al, 2006;Luoto et al, 2010).…”

Abstract. Landslide susceptibility maps are helpful tools to identify areas potentially prone to future landslide occurrence. As more and more national and provincial authorities demand for these maps to be computed and implemented in spatial planning strategies, several aspects of the quality of the landslide susceptibility model and the resulting classified map are of high interest. In this study of landslides in Lower Austria, we focus on the model form uncertainty to assess the quality of a flexible statistical modelling technique, the generalized additive model (GAM). The study area (15 850 km 2 ) is divided into 16 modelling domains based on lithology classes. A model representing the entire study area is constructed by combining these models. The performances of the models are assessed using repeated k-fold cross-validation with spatial and random subsampling. This reflects the variability of performance estimates arising from sampling variation. Measures of spatial transferability and thematic consistency are applied to empirically assess model quality. We also analyse and visualize the implications of spatially varying prediction uncertainties regarding the susceptibility map classes by taking into account the confidence intervals of model predictions. The 95 % confidence limits fall within the same susceptibility class in 85 % of the study area. Overall, this study contributes to advancing open communication and assessment of model quality related to statistical landslide susceptibility models.

“…4.2 | Using the hierarchical approach to communicate geomorphology and better inform water resources management in the Okavango Delta One overarching benefit of adopting a multi-scale perspective through the development of a nested hierarchical framework is to help non-specialists and decision-makers understand more fully how various parts of the system fit together and interact across scales, thereby enhancing insight into the functionality of the system as a whole (Brierley, 2009;Gregory & Lewin, 2015;Vervoort et al, 2014). In the Okavango catchment, for instance, there is a current, pressing need to understand the impacts of climate change, land use changes and water resource developments (e.g., dams, weirs, extensive extraction) in Angola, Namibia and Botswana on total annual flow volumes, seasonal flow variability, water quality, and sediment and nutrient loads in the Delta (Government of Denmark and Republic of Botswana, 2006;Kgathi et al, 2006;Pr€ opper & Gr€ ongr€ oft, 2015).…”

In addition, these technologies are helping to democratise parts of the research process through citizen science, particularly by allowing people to generate their own place-based knowledge and engage more fully in environmental management practice (Brierley, 2009;Brierley et al, 2006;Haywood et al, 2016;Vervoort et al, 2014).…”

A key skill that geomorphologists possess is the ability to use multi‐scale perspectives in their interpretations of landscapes. One way to gain these perspectives is with the use of nested hierarchical frameworks. In fluvial geomorphology, such frameworks help with assessment of large‐scale controls (e.g., tectonic activity, climate change) on the pattern and dynamics of smaller‐scale physical features (e.g., channels, floodplains, bars), and conversely illustrate how these smaller‐scale features provide the building blocks from which to make interpretations of fluvial processes and dynamics over larger spatial and temporal scales. Given the rapid pace of technological developments, the range of relatively inexpensive tools available for visualising and mapping landscapes at different spatial scales is expanding exponentially. In this paper, which focuses on the World Heritage‐listed Okavango Delta in Botswana, we demonstrate how various visualisations generated by different technologies at different spatial scales (catchment, landscape unit, reach, site and geomorphic unit) are providing critical baseline information to enhance interpretation and communication of fluvial geomorphology, with potential application in water resources management. In particular, our nested hierarchical approach could be used as an interactive communication tool for non‐specialists and embedded within existing and future management plans for the Delta. The construction of nested hierarchies that synthesise information and analyses can be a valuable addition to the environmental manager's toolkit.

“…Finally, what kind of work might a cultural physical geography do for geography as a whole? The ‘work’ of physical geography and geographers does not end with the research publication or presentation, but extends to consider how the practices and outputs of physical geography are embedded within wider systems of signification (Brierley 2009; Fryirs and Brierley 2009; Lane et al 2011; Thornes et al 2010; Trudgill 2003). By embracing a critical approach to culture, new research questions can be formulated, alternative approaches considered, and ‘downstream’ cultural work reorganised to facilitate positive change.…”

Human-environment relationships are increasingly regarded as complex and worthy of interdisciplinary scrutiny. In this context, several physical geographers have made calls for their subdiscipline to take a 'cultural turn' and engage more fully with human elements of environmental change. However, despite sharing a general commitment to thinking about the material implications of human behaviours, definitions proposed for a cultural physical geography lack theoretical rigour and consistency. This paper interrogates the prospects for a refreshed cultural turn in physical geography by situating it within its constitutive, historical and institutional dimensions. First, how might 'culture' be defined and constituted, and with what implications? This question recognises that conceptual work around culture depends upon the sociotheoretical paradigms that are chosen. Second, an exploration of key moments in the definition of geographical research projects and trajectories provides insight into why this turn has not happened before, and what kind of work was pursued in its place. Third, a cultural turn positions physical geography to do particular kinds of work within wider ecologies of knowledge production. Careful reflection on the methods and commitments of different approaches is needed to assess where and how such a project might be at all geographical. The notion of culture embraced and practised by physical geographers has material, epistemological, institutional and ethical implications. Broadening the scope of 'work' from the outputs to the outcomes of geographical practice creates the conceptual space for much needed reflection and dialogue. A cultural turn that acknowledges the 'webs of significance' within which physical geography is embedded presents a progressive trajectory of inquiry. key wordsnature ⁄ culture physical geography cultural turn integration history of geography epistemology
