Cultural eutrophication stimulated by anthropogenic-produced nutrients (nitrogen and phosphorus) represents one of the most common forms of compromised surface water quality in many developed and developing countries. The sources of nutrients causing eutrophication are many and varied, but diffuse sources of N and P of agricultural origin are a significant contributor. As a result many experts come together annually as part of the International Water Association’s specialist conference on diffuse pollution. This special issue is the result of some of the papers presented at the 2011 conference in Rotorua, New Zealand. Papers offered as part of the special were augmented by others whose collective aim was to link strategies in mitigating N and P losses from agricultural systems to effects or trends in receiving water bodies, cognisant of water quality objectives and limits and their potential financial implications.
This special issue also addressed wider issues such as data quality and the tools being used to collate and examine fate and transport pathways of nutrients and sediments, and their predicted effects. These papers demonstrate some methods of how to measure, monitor and remediate the effects of eutrophication in agricultural catchments and thereby inform good management and policy.
