The potential of citizen science to transform science: Lessons for a sustainable future
The authors analysed 8 citizen science projects within Accelerator Programme of the EU H2020 funded ACTION project that deal with environmental pollution. Citizen science involves the public in the scientific process, making research more relevant and responsive. Our findings show that this can lead to a more sustainable future, where science and society work together to solve pressing problems.
Let there be Skyglow—light pollution from a large outdoor music festival (Lollapalooza Berlin 2016)
Polarised light pollution on river water surfaces caused by artificial light at night from illuminated bridges and surroundings
Long-term drought effects on landscape water storage and recovery under contrasting landuses
Process-based, tracer-aided ecohydrological modelling and ML were combined to estimate the effects of long-term drought on water fluxes/storage in the Spree catchment. The recent major droughts resulted in declines in groundwater recharge (>40 %), evapotranspiration (up to 16 %) and soil moisture (up to 6 %). Groundwater levels may not recover in 15 years if precipitation anomalies persist.

Inland recreational fisheries contribute nutritional benefits and economic value but are vulnerable to climate change
The research team estimates that recreational fishing in lakes and rivers accounts for more than 11 per cent of the annually reported catches in inland fisheries worldwide. The analyzed total consumption value of harvested fish is around 10 billion US dollars per year. Due to climate change and direct human impacts on freshwater ecosystems, the productivity of important fish species is declining.
Flagship events and biodiversity conservation
While flagship species are a highly effective approach in conservation, this article proposes the distinct but complementary concept of flagship events: natural or anthropogenic occurrences that attract public attention. Flagship events have high potential value for biodiversity conservation by engaging people with wildlife and helping to garner support for conservation efforts.
Global introductions and environmental impacts of freshwater megafish
The authors investigated the introductions of freshwater megafish on a global scale and assessed their environmental impacts. Of the 134 extant freshwater megafish species, 46% have been introduced to new environments, and of these, 69% have established self-sustaining alien populations and posed negative impacts on native species through nine different mechanisms.
