Short summary
Water companies in the UK have found that drinking water from upland reservoirs is becoming browner. This is costly to treat and if the dissolved organic matter that causes the colour isn't removed potentially harmful chemicals could be produced. Land management around reservoirs has been suggested as a way to reduce water colour. We reviewed the available literature to assess whether this would work. There is limited evidence available to date, although forestry appears to increase colour.

Short summary
Many peatlands around the world are eroding and causing carbon losses to the atmosphere and to freshwater systems. To accurately report emissions from peatlands we need to understand how much of the eroded peat is converted to CO2 once exposed to the atmosphere. We need more direct measurements of this process and a better understanding of the environmental conditions that peat is exposed to after it erodes. This information will help quantify the emissions savings from peatland restoration.

In this paper, we identify potential negative social tipping points linked to Earth system destabilization and draw on related research to understand the drivers and likelihood of these negative social tipping dynamics, their potential effects on human societies and the Earth system, and the potential for cascading interactions and contribution to systemic risks.

Short summary
Lakes worldwide are changing and under threat due to stressors such as overload of nutrients, increased input of organic carbon (“browning”), and climate change, which may cause reduced water volume, salinization, or even loss of waterbodies. Some of these changes are abrupt to the extent that they can be characterized as tipping points for that particular system. Such changes may also cause increased release of greenhouse gases, and lakes are major players in the global climate in this context.

Short summary
Peatlands have been subject to a range of land management regimes over the past century. This has affected the amount of carbon that drains into surrounding streams and rivers. In our study, we measured carbon concentrations in streams draining from drained, non-drained, and restored areas of the Flow Country blanket bog in N Scotland. We found that drained peatland had higher concentrations and fluxes of carbon relative to non-drained areas. Restored peatland areas were highly variable.

We measured element losses and impacts on water quality following a wildfire in Sweden. We observed the largest carbon and nitrogen losses during the fire and a strong pulse of elements 1–3 months after the fire that showed a fast (weeks) and a slow (months) release from the catchments. Total carbon export through water did not increase post-fire. Overall, we observed a rapid recovery of the biogeochemical cycling of elements within 3 years but still an annual net release of carbon dioxide.

Short summary
Managing drinking water catchments to minimise water colour could reduce costs for water companies and save their customers money. Brown-coloured water comes from peat soils, primarily around upland reservoirs. Management practices, including blocking drains, removing conifers, restoring peatland plants and reducing burning, have been used to try and reduce water colour. This work brings together published evidence of the effectiveness of these practices to aid water industry decision-making.
