- Wetlands are often vital physical and social components of a country’s natural capital, as well as providers of ecosystem services to local and national communities. We performed a network analysis to prioritize Sustainable Development Goal (SDG) targets for sustainable development in iconic wetlands and wetlandscapes around the world. The analysis was based on the information and perceptions on 45 wetlandscapes worldwide by 49 wetland researchers of the Global Wetland Ecohydrological Network (GWEN). We identified three 2030 Agenda targets of high priority across the wetlandscapes needed to achieve sustainable development: Target 6.3—“Improve water quality”; 2.4—“Sustainable food production”; and 12.2—“Sustainable management of resources”. Moreover, we found specific feedback mechanisms and synergies between SDG targets in the context of wetlands. The most consistent reinforcing interactions were the influence of Target 12.2 on 8.4—“Efficient resource consumption”; and that of Target 6.3 on 12.2. The wetlandscapes could be differentiated in four bundles of distinctive priority SDG-targets: “Basic human needs”, “Sustainable tourism”, “Environmental impact in urban wetlands”, and “Improving and conserving environment”. In general, we find that the SDG groups, targets, and interactions stress that maintaining good water quality and a “wise use” of wetlandscapes are vital to attaining sustainable development within these sensitive ecosystems.

- Aim: The aims of this study were to evaluate the self-reported driving abilities and use of visual and hearing aids for driving, among older adults with varying degrees of hearing impairment (HI), vision impairment (VI) and dual sensory impairment (DSI). Visual processing related to driving performance was also assessed to provide a laboratory-based index of driving ability and safety. The research examined the associations between self-reported and clinically measured vision and hearing, and how they related to the level of comfort in various driving situations and the use of hearing and vision aids (spectacles) when driving.Method: Participants included 109 older adults (58 women, 51 men) aged over 60 years (M age = 69.5 years (SD = 5.25), age range: 60–87) who held a valid driver's license. Following attendance at the testing session that involved clinical measures of vision and hearing and an assessment of visual processing abilities, the participants were categorized into four groups according to their hearing and vision abilities: no visual or hearing impairment (NI), corrected visual impairment (CVI), hearing impairment (HI), and corrected visual impairment combined with hearing impairment (CVHI). All participants filled in a questionnaire covering subjective measures of vision, hearing, driving habits, and use of vision and hearing aids.Results and Conclusion: There was a strong association between most of the subjective and objective measures of both hearing and vision, which indicates that participants in this study were aware of their abilities to some extent. Better hearing and vision measures were associated with higher level of comfort in several traffic situations. The results also show that spectacles are used more than hearing aids when driving (95% versus 57% of the time respectively). In addition, both the measured and the experienced benefits of hearing aids were significantly associated with the amount of hearing aid use when driving. The findings of this study provide the basis for larger scale studies to explore the impact of hearing and visual impairment on driving and the use of vision and hearing aids and should also include participants who have visual impairment even with their optimal optical correction to fully explore these effects.

- Hydrological connectivity describes the water-mediated transfer of mass, energy, and organisms between landscape elements and is the foundation for understanding how individual elements such as wetlands and streams integrate to support ecosystem services and nature-based solutions in the landscape. Hydrological connectivity of geographically isolated wetlands (GIWs)-that is, wetlands without persistent surface water connections-is particularly poorly understood. To better understand GIW hydrological connectivity, we use a novel chloride mass-balance approach to quantify the local runoff generation (defined as precipitation minus evapotranspiration, assuming negligible long-term water storage) for 260 GIW subcatchments across North America. To evaluate hydrological connectivity, we compare the estimated local runoff from GIW subcatchments with the catchment-average runoff. These comparisons provide three novel insights regarding the magnitude and variability of GIW hydrological connectivity. First, across 10 study regions, GIW subcatchments generate runoff at 120% of the mean catchment rate, implying they are well-connected elements of the larger hydrologic landscape. Second, there is substantial heterogeneity in runoff generation among GIW subcatchments, which may enable support for a wide array of ecosystem functions and services. Finally, observed heterogeneity in runoff generation was largely uncorrelated to simple linear geographic predictors, indicating that GIW landscape position cannot reliably predict hydrological connectivity. In stark contrast to a priori legal assumptions that GIWs exhibit low or no hydrological connectivity, our results suggest that GIW subcatchments are active landscape features in runoff generation.

Wetlands as large-scale nature-based solutions : Status and challenges for research, engineering and management

Tidskriftsartikel (refereegranskat)abstract
- Wetlands are often considered as nature-based solutions that can provide a multitude of services of great social, economic and environmental value to humankind. Changes in land-use, water-use and climate can all impact wetland functions and services. These changes occur at scales extending well beyond the local scale of an individual wetland. However, in practical applications, engineering and management decisions usually focus on individual wetland projects and local site conditions. Here, we systematically investigate if and to what extent research has addressed the large-scale dynamics of landscape systems with multiple wetlands, hereafter referred to as wetlandscapes, which are likely to be relevant for understanding impacts of regional to global change. Although knowledge in many cases is still limited, evidence suggests that the aggregated effects of multiple wetlands in the landscape can differ considerably from the functions observed at individual wetland scales. This applies to provisioning of ecosystem services such as coastal protection, biodiversity support, groundwater level and soil moisture regulation, flood regulation and contaminant retention. We show that parallel and circular flow-paths, through which wetlands are interconnected in the landscape, may largely control such scale-function differences. We suggest ways forward for addressing the mismatch between the scales at which changes take place and the scale at which observations and implementation are currently made. These suggestions can help bridge gaps between researchers and engineers, which is critical for improving wetland function-effect predictability and management.
