Our Freshwater 2026 w/ Professor Troy Baisden

Last week, the Ministry for the Environment together with Stats New Zealand released Our Freshwater 2026, a major report on the state of Aotearoa’s freshwater systems based on decades of data. The report highlights both long-term improvement and deterioration of waterways nationwide, with particular focus on groundwater sources and the impacts of agricultural land use and the climate crisis on water quality. 

I spoke to Troy Baisden, co-president of the New Zealand Association of Scientists and Adjunct Professor at Victoria University of Wellington, about what the findings of this report mean and also about the strengths and limitations of freshwater reporting.
