The Quality of Clarity: Lessons from the Sixty‐Year Struggle to Maintain the Purity of Lake Taupō

open access: yesKōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 2, June 2026.
Sixty years of effort to protect the exceptionally clear water of Lake Taupō, the largest lake in Aotearoa New Zealand, show how environmental memory can help manage a cultural and natural resource. I describe how water clarity and quality in this lake have been protected, through managing soil erosion and phosphorus flows during the 1960s–1980s, and ...
