The Climate Changes, Impacts & Implications project ran from 2012 to 2016 and aimed to update and improve projections of climate trends, variability and extremes across New Zealand out to 2100.

Air quality is almost never consistent across NZ’s towns – polluted air can readily be transported on the breeze and accumulate in different locations.

Constructed wetlands, detention bunds, woodchip denitrification filters and planted riparian buffers are examples of a growing suite of edge-of-field and farm-scale mitigation systems that are being trialled across rural New Zealand to reduce the impact of diffuse pollution on freshwater quality
