Almost half of Aotearoa New Zealand’s CO2-equivalent greenhouse gas emissions come from agriculture. This is a much higher proportion than most other countries – globally, agricultural emissions average around 7.5% of a country’s total emissions.

The Inner Hauraki Gulf/Tīkapa Moana ecosystem is facing proliferations of algae, de-oxygenation, reduced pH (acidification), reduced water clarity, and muddier sediments arising from historical and future land-derived contaminant inputs.

Marsden-funded research investigating how erupting volcanoes can cause deadly and damaging tsunamis.

Clouds over the ocean, and how they trap or emit radiation from the sun, are partly influenced by the biology, biogeochemistry and physics of the surface ocean below.

The eFlows Explorer webtool is designed to aid broad-scale river flow management planning across New Zealand

Community Air Watch Arrowtown enables members of the public to use new technologies to participate in studies of air quality.

Schools Air Watch enables school classes to use new technologies to participate in a study of air quality in their own community.

Community Air Watch Invercargill enables members of the public to use new technologies to participate in studies of air quality.

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

Te Nehenehenui (previously Maniapoto Māori Trust board) and NIWA are working collaboratively to support Ngāti Maniapoto whānau to reconnect with and participate in the assessment of their freshwater according to their values.
