Once known as a biologically dead river, the Scheldt continues to show signs of recovery. Our analyses show rising oxygen levels and decreasing nutrient levels, but also point out that increasing chloride concentrations and turbidity levels can undermine the restoration of this complex estuarine ecosystem. In the magazine (starting at page 6, only in Dutch) you can read more about the main findings related to hydrology, morphology, and ecology of the Scheldt estuary. The underlying reports are finished and will be published soon.

Science Day 2022: participation AECO to the Science Festival Ghent (November 27th, 2022)
During the Science Festival in Ghent on 27 November 2022, AECO will give children the opportunity to take their first steps as water journalists in the underwater world of macro-invertebrates and to research and learn more about freshwater ecology.

Over eten: Prof. Peter Goethals shared his research and expertise on fish from polluted sea and rivers in in the vrt program 'Over eten,' to be seen via VRT max. (only available in Dutch)
Cod and salmon are by far the most popular fish on our plates. But like 90% of the fish we eat, they are imported. In doing so, we grossly overlook surprisingly delicious fish from our North Sea. In 'Over eten' they find out what fish we catch from the North Sea, how healthy fish is from a polluted sea and river, and how we can get more fish from our own sea in the future..
Surrounded by intense anthropogenic activities, urban rivers have become one of the major greenhouse gas sources. Our research recently revealed how water pollution can amplify the emissions of rivers. These outcomes were highlighted in a recently published article in BBC Future Planet. The cited research is a part of a thorough investigation in the Cuenca river basin in Ecuador, that was published in Biogeosciences and Water Research. The latter demonstrated that natural wastewater treatment plants are also releasing high amount of CO2 and CH4 as a result of regular influx of pollutants. These studies were supported by VLIR-UOS via the Biodiversity Network Ecuador, which aims to find innovative solutions for improving water management.
Research in the context of high mountain lakes of the VLIR-UOS projects in Ecuador and cooperation with HOGent and UTN, is presented on the cover of the journal Biotropica.
