Like many parts of the world, Aotearoa New Zealand's waterways are under immense pressure from anthropogenic impacts that will be amplified by effects climate change. After decades rising public concern, progress had been made on freshwater policy for protection and restoration country's waterbodies. However, a new Government, elected at end 2023 threatens to undo progress, implement economic policies worsen crisis. This article was prompted an open letter, signed 51 experts national regional leaders issues, urged Government not reverse or undermine made. It describes state waterways, provides brief history developments in Zealand highlights influence agricultural sector its environmental policy.

Abstract Small rivers support high levels of biodiversity, being especially sensitive to the effects global change. Temporal records community composition in minimally impaired streams can be used explore trends biodiversity response climate change and natural temporal variation. We approached comparison two time periods (2003–2008 2016–2020) study whether diatom assemblages changed over twenty-three mountain range Picos de Europa (Northern Spain). The stream’s water chemistry indicated significant decreases N_NO 3 − P_PO 4 3− content time. In these disturbed streams, specific was dominated by Achnanthidium pyrenaicum , minutissimum Cocconeis euglypta . PERMANOVA analyses did not identify changes assemblage between or river types. Diatom indices (e.g. IPS, NORTIdiat) good ecological status relatively alpha diversity values were found during studied years. Although evenness showed a decrease time, stability river-type reference should considered as an indicator persistence importance when monitoring following condition approach.
