“…A higher proportion of respondents from the Grand watershed report having meadows and wetlands than those from the Upper Thames watershed. Though certain characteristics differ significantly across samples, they are still fairly similar, and the differences observed are similar to those of previous benefit transfer assessments (e.g., Brouwer, Bliem, & Getzner, 2016;Johnston & Duke, 2010;Martin-Ortega, Brouwer, Ojea, & Berbel, 2012;Oh, 2010). In addition, our samples are reasonably similar to each watershed's population of farm operators in terms of gender, age, and income.…”

We examined the reliability and validity of transferring estimates of marginal willingness to accept and compensating surplus. In doing so, we used data from two case studies applying choice experiments to elicit landowner preferences for incentive‐based wetland conservation programs in two adjacent watersheds in Southern Ontario, Canada (Grand and Upper Thames Rivers in parallel in 2013). The choice experiment data were modeled in willingness to accept space using a generalized multinomial logit. Transfer reliability was investigated by calculating transfer errors, while validity was investigated by testing the equality of utility functions as well as by assessing the similarity of welfare estimates using traditional hypothesis tests and equivalence tests. The main findings are that transfers of willingness to accept are similar to existing transfers of willingness to pay in terms of validity and reliability. Additionally, a sensitivity analysis finds that including demographic variables in the choice model can lead to lower transfer validity though does not substantially affect reliability. Though further research is required, our results suggest that willingness to accept can be transferred as part of policy analyses.

“…We assume that contextual factors play a decisive role here. This is at least suggested by the cross-country studies conducted by Brouwer et al [75], which imply that different spatial, socio-economic-demographic, cultural, and institutional settings may correlate with a different perception of NBS.…”

“…For example, Sheng et al [110] found that household income and the amount of government subsidy received for owned pasture area correlated with the positive support of a restoration project. However, Brouwer et al [75] found that this correlation is not universal but only occurs for lower-income households depending on the respective national context. Furthermore, educational level seems to have a clear positive effect on perceptions of NBS [74,111].…”

“…Studies have also explored how interaction with NBS shape individual perceptions of NBS. People who directly interact with NBS report higher awareness of both the potential positive effects of NBS and of risks compared to people with lower degrees of interaction, such as tourists [74], users compared to non-users [75], or NBS sites that are less accessible [71].…”

Reducing Hydro-Meteorological Risk by Nature-Based Solutions: What Do We Know about People’s Perceptions?

Nature-based solutions (NBS) have recently received attention due to their potential ability to sustainably reduce hydro-meteorological risks, providing co-benefits for both ecosystems and affected people. Therefore, pioneering research has dedicated efforts to optimize the design of NBS, to evaluate their wider co-benefits and to understand promoting and/or hampering governance conditions for the uptake of NBS. In this article, we aim to complement this research by conducting a comprehensive literature review of factors shaping people’s perceptions of NBS as a means to reduce hydro-meteorological risks. Based on 102 studies, we identified six topics shaping the current discussion in this field of research: (1) valuation of the co-benefits (including those related to ecosystems and society); (2) evaluation of risk reduction efficacy; (3) stakeholder participation; (4) socio-economic and location-specific conditions; (5) environmental attitude, and (6) uncertainty. Our analysis reveals that concerned empirical insights are diverse and even contradictory, they vary in the depth of the insights generated and are often not comparable for a lack of a sound theoretical-methodological grounding. We, therefore, propose a conceptual model outlining avenues for future research by indicating potential inter-linkages between constructs underlying perceptions of NBS to hydro-meteorological risks.

“…Most of the area has been drained for agricultural purposes. As a consequence, connectivity between the Danube and the floodplains is very limited [18]. The Danube river in the Braila Islands section has been ranked as a heavily modified water body according to criteria 2.1 (embankment works) due to the hydro-technical works on 79% of the river stretch sector and a candidate to "heavily modified" according with the WFD criteria 2.2 (regulation works) as a result of dredging of 21% of the river bed for intensive navigation.…”

Long-term ecological research (LTER) sites need a periodic assessment of the state of their ecosystems and services in order to monitor trends and prevent irreversible changes. The ecological integrity (EI) framework opens the door to evaluate any ecosystem in a comparable way, by measuring indicators on ecosystem structure and processes. Such an approach also allows to gauge the sustainability of conservation management actions in the case of protected areas. Remote sensing (RS), provided by satellite, airborne, or drone-borne sensors becomes a very synoptic and valuable tool to quickly map isolated and inaccessible areas such as wetlands. However, few RS practical indicators have been proposed to relate to EI indicators for wetlands. In this work, we suggest several RS wetlands indicators to be used for EI assessment in wetlands and specially to be applied with unmanned aerial vehicles (UAVs). We also assess the applicability of multispectral images captured by UAVs over two long-term socio-ecological research (LTSER) wetland sites to provide detailed mapping of inundation levels, water turbidity and depth as well as aquatic plant cover. We followed an empirical approach to find linear relationships between UAVs spectral reflectance and the RS indicators over the Doñana LTSER platform in SW Spain. The method assessment was carried out using ground-truth data collected in transects. The resulting empirical models were implemented for Doñana marshes and can be applied for the Braila LTSER platform in Romania. The resulting maps are a very valuable input to assess habitat diversity, wetlands dynamics, and ecosystem productivity as frequently as desired by managers or scientists. Finally, we also examined the feasibility to upscale the information obtained from the collected ground-truth data to satellite images from Sentinel-2 MSI using segments from the UAV multispectral orthomosaic. We found a close multispectral relationship between Parrot Sequoia and Sentinel-2 bands which made it possible to extend ground-truth to map inundation in satellite images.
