Analyzing the extent and use of impervious land in rural landscapes
Moser, Andreas; Van Vliet, Jasper; Wissen Hayek, Ulrike; et al. (2024)
Geography and Sustainability
The amount of impervious surface is increasing rapidly worldwide. Although urban expansion has been studied extensively, the alteration of impervious land cover in rural regions remains under-examined. In particular, insights into the utilization of these sealed surfaces are crucially needed to unravel the underlying dynamics of land use changes beyond urban areas. This study focuses on rural regions from a Swiss case study and presents an analysis of the use of sealed surfaces in such regions, rather than solely quantifying the extent of sealed surfaces. Utilizing a synergistic approach that merges detailed cadastral plans with very-high-resolution remote sensing imagery and sophisticated deep learning algorithms, we characterized the uses of sealed surfaces, including buildings and their surroundings. Our findings reveal that 2.1 % of the study area’s rural regions comprises sealed surfaces - an area comparable to the sealed surfaces in the urban regions. Within these rural regions, transport infrastructure represents 68 % of this impervious surface. Buildings account for 12 %, and their surroundings, constituting 13 %, are utilized primarily for agricultural purposes, including farming and livestock activities. The deep learning approach achieved a classification accuracy of 72 % for a shallow model and 79 % for a deeper model, indicating that mapping building types is possible with reasonable accuracy. The outcomes of this study underscore the critical need to factor in the presence and utilization of impervious land cover within rural regions for the sustainable management of land resources.

Uncertainties in ecosystem services assessments and their implications for decision support – A semi-systematic literature review
Walther, Franziska Ellen; Barton, David N.; Schwaab, Jonas; et al. (2025)
Ecosystem Services
Ecosystem services (ES) assessments are rarely integrated into decision-making processes, with uncertainties often cited as a major barrier. While various uncertainties, such as modelling and data uncertainties, are inherent in ES assessments, their role in uptake of ES assessment results in decision-making remains unclear. We conducted a semi-systematic literature review of scientific papers assessing ES to reveal how uncertainties in ES assessments relate to ES uptake, i.e., the potential use of ES assessment results by decision makers. We performed logistic regressions to analyse the influence of three main sources of uncertainty on ES uptake, i.e., (i) modelling uncertainties, (ii) uncertainties related to qualitative and quantitative descriptions of scenarios, and (iii) uncertainties related to the transfer of ES assessment results into decision-making. Furthermore, we investigated if stakeholder involvement plays a role in ES uptake. First, and most importantly, the results indicate that clarifying the policy context can decrease decision uncertainty and thus improve ES uptake. Referring to a specific policy, following a decisive study purpose and documenting the intended policy entry point are factors that significantly enhance ES uptake. Second, the way how ES are modelled is related to ES uptake. Our results show that using multiple models to assess ES significantly promotes ES uptake. Third, involving stakeholders in ES assessments is significantly associated with increased documented uptake. We discuss that explicitly anchoring the assessment in a policy context increases the salience and timeliness of an ES study, assessing model uncertainties can lead to more credible results, and involving stakeholders can provide more legitimacy, which together increase the potential for ES assessments and their results to be used in decision-making. This study encourages future ES assessments to integrate uncertainties in order to support informed decision-making and promote the conservation and sustainable management of ecosystems and their services.

Catalyzing Transformations to Sustainability in the World's Mountains
Klein, Julia A.; Tucker, Catherine M.; Nolin, Anne W.; et al. (2019)
Earth's Future
Mountain social‐ecological systems (MtSES) are vital to humanity, providing ecosystem services to over half the planet's human population. Despite their importance, there has been no global assessment of threats to MtSES, even as they face unprecedented challenges to their sustainability. With survey data from 57 MtSES sites worldwide, we test a conceptual model of the types and scales of stressors and ecosystem services in MtSES and explore their distinct configurations according to their primary economic orientation and land use. We find that MtSES worldwide are experiencing both gradual and abrupt climatic, economic, and governance changes, with policies made by outsiders as the most ubiquitous challenge. Mountains that support primarily subsistence‐oriented livelihoods, especially agropastoral systems, deliver abundant services but are also most at risk. Moreover, transitions from subsistence‐ to market‐oriented economies are often accompanied by increased physical connectedness, reduced diversity of cross‐scale ecosystem services, lowered importance of local knowledge, and shifting vulnerabilities to threats. Addressing the complex challenges facing MtSES and catalyzing transformations to MtSES sustainability will require cross‐scale partnerships among researchers, stakeholders, and decision makers to jointly identify desired futures and adaptation pathways, assess trade‐offs in prioritizing ecosystem services, and share best practices for sustainability. These transdisciplinary approaches will allow local stakeholders, researchers, and practitioners to jointly address MtSES knowledge gaps while simultaneously focusing on critical issues of poverty and food security.
A multi-scale analysis on the importance of patch-surroundings for farmland birds
Klein, Noëlle; Grêt-Regamey, Adrienne; Herzog, Felix; et al. (2023)
Ecological Indicators
Agricultural intensification has profoundly changed agricultural landscapes with important biodiversity impacts. There is increasing knowledge on the general effects of landscape structure and management practices on plant and animal species but understanding the role of surrounding landscape structure for patch-scale biodiversity is more complex. While it can be reasonably assumed, that adjacent habitats are more important than more distant ones, the importance of landscape structure has often been tested at the landscape scale but rarely at smaller scales such as patch-surroundings. We assessed the influence and interdependences of landscape composition and configuration (LCC) and land use/land cover (LULC) on bird species richness and abundance through a multi-scale analysis with specific focus on the surrounding patches. In two agricultural regions in Switzerland, we collected point data of birds on 36 transects (500 m) and combined them with detailed spatial data on LULC. Bird richness and abundance were correlated to sets of landscape metrics as proxies for LCC computed at the transect-scale as well as for the patch surroundings. We analysed patch LULC as well as the most important patch-surrounding metrics using generalized linear mixed models. The results illustrate that patch LULC is the most important predictor of bird richness and abundance. Woody structures increase bird richness, followed by extensive management on patch scale. On the transect-scale semi-natural structure and heterogeneous LCCs are beneficial for bird richness and abundance. The effect of patch-surrounding structure LCCs is only small and interacts with patch LULC. Birds in grassland benefit from fallows in the surroundings, while in cropland they tend to respond positively to surrounding extensive grassland. Our results highlight that considering surroundings can help improve patch-based biodiversity assessments, which will then better predict the consequences of farmland management and make the outcome more applicable for practice.
