DOI: 10.1016/j.landusepol.2018.03.048
Abstract: Excess nutrients cause eutrophication of freshwaters all over the world. Decision-support tools are needed to assess nutrient discharges from catchments. This paper used a 28-year nutrient-discharge, hydroclimate and land-use history of small rural catchments to… read more here.

DOI: 10.1111/gcb.14477
Abstract: Freshwater ecosystems play a major role in global carbon cycling through the breakdown of organic material and release of greenhouse gases (GHGs). Carbon dioxide (CO2 ) and methane (CH4 ) emissions from lakes, wetlands, reservoirs… read more here.
