“…Follow‐up surveys indicated development of research and teamwork skills and garnered suggestions for improving and furthering the project. Křeček, Palán, Pažourková, and Stuchlík (2019) reported on a water and precipitation quality monitoring project running for over 20 years in a mountain catchment affected by acidification and logging in the Czech Republic. After each annual two‐week field program, specific tests were set evaluating participants' acquisition of new knowledge and skills.…”

The benefits and negative impacts of citizen science applications to water as experienced by participants and communities

Citizen science is proliferating in the water sciences with increasing public involvement in monitoring water resources, climate variables, water quality, and in mapping and modeling exercises. In addition to the well-reported scientific benefits of such projects, in particular solving data scarcity issues, it is common to extol the benefits for participants, for example, increased knowledge and empowerment. We reviewed 549 publications concerning citizen science applications in the water sciences to examine personal benefits and motivations, and wider community benefits. The potential benefits of involvement were often simply listed without explanation or investigation. Studies that investigated whether or not participants and communities actually benefitted from involvement, or experienced negative impacts, were uncommon, especially in the Global South. Assuming certain benefits will be experienced can be fallacious as in some cases the intended benefits were either not achieved or in fact had negative impacts. Identified benefits are described and we reveal that more consideration should be given to how these benefits interrelate and how they build community capitals to foster their realization in citizen science water projects. Additionally, we describe identified negative impacts showing they were seldom considered though they may not be uncommon and should be borne in mind when implementing citizen science. Given the time and effort commitment made by citizen scientists for the benefit of research, there is a need for further study of participants and communities involved in citizen science applications to water, particularly in low-income regions, to ensure both researchers and communities are benefitting.

“…Finally, we excluded papers if the citizen science scheme focused on collecting data solely on the abiotic environment. These schemes included those collecting data on water quality (Křeček et al 2019) or on soil quality (Bone et al 2012). Where papers had used data from multiple schemes, we recorded all of the schemes included in the research.…”

Citizen science schemes enable ecological data collection over very large spatial and temporal scales, producing datasets of high value for both pure and applied research. However, the accuracy of citizen science data is often questioned, owing to issues surrounding data quality and verification, the process by which records are checked after submission for correctness. Verification is a critical process for ensuring data quality and for increasing trust in such datasets, but verification approaches vary considerably between schemes. Here, we systematically review approaches to verification across ecological citizen science schemes that feature in published research, aiming to identify the options available for verification, and to examine factors that influence the approaches used. We reviewed 259 schemes and were able to locate verification information for 142 of those. Expert verification was most widely used, especially among longer-running schemes, followed by community consensus and automated approaches. Expert verification has been the default approach for schemes in the past, but as the volume of data collected through citizen science schemes grows and the potential of automated approaches develops, many schemes might be able to implement approaches that verify data more efficiently. We present an idealised system for data verification, identifying schemes where this system could be applied and the requirements for implementation. We propose a hierarchical approach in which the bulk of records are verified by automation or community consensus, and any flagged records can then undergo additional levels of verification by experts.

“…pH was measured with combination electrodes, and conductivity was measured by the radiometer conductometric sensor [40]. A portable photometer Paqualab 430-550 (ELE International, Milton Keynes, UK) was used to analyse concentrations of focused ions NH 4 + , NO 3 − , and SO 4 2− more frequently during the weekly field campaigns (four to six a year) [20].…”

“…Moreover, the orographic enhancements of precipitation and pollutant deposition are considered significantly greater for snowfall than for rainfall [18]. In regions with high levels of air pollution, forest stands can increase acid deposition through their relatively high leaf area and roughness of the canopy and, thus, counteract the beneficial effects of forests on the water quality at stream headwaters [20]. UNEP [21] called for a reduction of the atmospheric acid deposition in headwater catchments to mitigate the progressive downstream acidification of rivers and the ocean.…”

“…Although most water quality regulations, legislation, and sampling are promulgated for base-flow conditions, Bolstad and Swank [23] warned of land-use impacts on water chemistry and biota during stormflow. In snow-rich catchments, water quality is affected particularly by seasonal acidification associated with the direct runoff from melting snow in the spring [20].…”

In headwaters, snowmelt affects the replenishment of water resources as well as the occurrence of natural hazards. The environmental impacts of snowpack were analysed in a small forest catchment (Jizera Mountains, Czech Republic) in the context of forest dynamics, atmospheric deposition, and climate, 1982–2021. Snowmelt dominates in March–May with 41% of the long-term annual water yield; however, there is also seasonal acidification of stream water. Forest clear-cutting together with air pollution control has contributed to a decrease in the acid atmospheric load, but, in the spring, streams’ pH is often below the environmental threshold of 5.3. Snowmelt volumes did not show significant transformation with forest canopy and do not affect summer low flows. Peak flows in the springtime do not exceed summer flash floods (frequencies up to 0.13 against 0.02). Mean annual air temperature is increasing by 0.26 ± 0.08 °C per decade with more intensive warming (0.64 ± 0.1 °C per decade) in the winter season. The seasonal reduction in snowpack duration and maximum snow water equivalent (5.5 ± 1.2 days and 34 ± 8.6 mm per decade) corresponds with the largest drop in snow cover duration reported in zones of seasonal temperatures ranging from −5° to +5 °C.
