Browning of surface waters, also known as brownification, is a process of decreasing water transparency, particularly in boreal lakes surrounded by intensively managed forests and wetlands. In this paper, we review the ecological consequences and ecosystem-based management (EBM) of browning through a systematic review approach and adopt an interdisciplinary approach to formulating new governance of this complex phenomenon.To understand the effects of browning on the recreational value of freshwaters, we present primary survey data on public perceptions of recreational fishing tourists on water quality in Finland. We identify a need to develop EBM beyond the EU's Water Framework Directive (WFD) to fully account for the extensive implications of browning. We also highlight the need for a better understanding of the within-lake microbial processes to estimate the browning-associated changes in the greenhouse gas balance of lakes.Tourist perceptions of the quality of waterbodies in Finland were largely in agreement with the general proportion of waterbodies classified in a good or excellent ecological status class, but these perceptions may be detached from biological quality assessment criteria. Consequently, we suggest that the EBM of inland waters should improve the utilization of information on not only biogeochemical processes but also users' perspectives on aquatic ecosystems beyond the EU WFD.

The spatial and temporal variation of Nuphar lutea chlorophyll content was studied in 12 small lakes in Finland to clarify the bioindicator potential of N. lutea chlorophyll content for monitoring lake brownification. Significant in-lake variation in water colour and total phosphorus concentration was observed in a few study lakes. At highest, the in-lake variation for water colour was 13% and for total phosphorus concentration 27%. However, the in-lake variation in water quality did not coincide with significant in-lake variation of N. lutea chlorophyll content. The total chlorophyll concentration (chlorophyll a + b) varied in a few lakes, but the chlorophyll a and b ratio (chlorophyll a:b) did not change within the lakes. The chlorophyll a:b, however, varied between lakes and decreased significantly with increasing water colour and total phosphorus concentration in Nuphar lutea individuals collected near the lake outflow. The chlorophyll content of N. lutea did not show significant temporal variation during the one-week sampling period despite variable weather conditions. Chlorophyll a:b of N. lutea seems to be a possible bioindicator for monitoring brownification, as it can differentiate lakes from each other based on a small difference in water colour but does not react to short-term in-lake variations in the water quality.
