June 2025 Newsletter

This last month I was fortunate to be in Aarhus, Denmark for the LUWQ2025 conference. This is an International Interdisciplinary Conference on Land Use and Water Quality, Agriculture and the Environment. There was an impressive range of researchers and regulators discussing the challenges facing Europe and their water quality. One of the distinct advantages we have in Australia is that we are late to the party relative to Europe, so it gives us a bit of foresight into the challenges that we will face in the future.

European agricultural practices have polluted groundwater, surface and marine water to a significant level. Particularly nitrate. This is because they like to spread manure on their paddocks and fertilise. The EU is taking this pollution seriously, and have issued The NitratesDirective, which aims to protect water quality across Europe. Under this Directive: EU countries must: Designate Nitrate Vulnerable Zones (NVZs), establish Codes of Good Agricultural Practice and establish action programmes to be implemented by farmers within NVZs on a compulsory basis.

What I was struck with, was the sense of urgency in the room, the real concern of all and the massive challenge faced to endeavour to get nitrate concentrations down to the mandated levels. So, what to learn from all of this? Intensive agriculture poses significant impacts to water quality. To get real action on the ground, actions need to be regulated, mandated and criteria established to protect the environment.
