No ‘silver bullet’ for agricultural emissions – In the News

Sarah-Jane O'Connor posted in on October 20th, 2016.

The Parliamentary Commissioner for the Environment Dr Jan Wright released her latest report on Wednesday, this time turning her attention to the issue of agricultural greenhouse gases. Methane and nitrous oxide – dubbed the biological greenhouse gases – make up about half New Zealand’s total emissions, Dr Wright said. If New Zealand had a chance […]

Environment Commissioner reports on agricultural greenhouse gases – Expert Reaction

Sarah-Jane O'Connor posted in on October 19th, 2016.

A new report from the Parliamentary Commissioner for the Environment, Jan Wright, has called for New Zealanders to work together to tackle the “complex problem of the biological greenhouse gases from agriculture”. Methane and nitrous oxide form about half of New Zealand’s greenhouse gas emissions, but there have been many false starts in dealing with […]

Dacia Herbulock posted in on September 11th, 2014.

Destruction of the planet’s protective ozone layer is slowing, according to the latest scientific assessment, but full impacts on global climate are still coming clear. The first comprehensive update on global ozone in four years has been released today from the United Nations Environmental Programme (UNEP) and the World Meteorological Organisation (WMO). The Assessment for Decision-Makers, […]

TVNZ/One News: Scientists work with farmers to cut emissions

Peter Griffin posted in on June 10th, 2010.

In order to help farmers make the best greenhouse gas mitigation choices, NIWA scientists are travelling the country to learn more about how paddocks emit these gases. The study will include  looking at the effectiveness of chemical sprays currently used to decrease nitrous oxide emissions from agricultural land. An excerpt: (read in full here) “Farmer […]

Agricultural emissions – the global effort to reduce them

Peter Griffin posted in on March 31st, 2010.

Officials and scientists from 28 countries that have signed up to the Global Research Alliance will arrive in Wellington next week to hammer out a plan to “produce more food with fewer emissions”.

ODT: Greenhouse gases measured remotely

Peter Griffin posted in on February 22nd, 2010.

Tuangane Matangi reports, in the Otago Daily Times, on a new technology which enables scientists to measure nitrous oxides emissions from paddocks more easily and cost-effectively. The technology, developed by AgResearch, allows gas samples to be taken from grass in paddocks without the need for manual, on site sampling.  Instead, closed chambers are placed on […]

Nitrous oxide – the big baddie of greenhouse gases

Peter Griffin posted in on August 28th, 2009.

Nitrous oxide, which comes from natural and man-made sources, is the most damaging of greenhouse gases according to scientists who have been modeling the impact of the gas on the ozone layer and on the climate. The agricultural sector is a major producer of nitrous oxide and extensive research is underway in New Zealand under […]

NZ methane mitigation research in New Scientist

Peter Griffin posted in on December 27th, 2008.

The current issue of New Scientist features an interesting article which draws on research underway in New Zealand and highlights the challenges the world faces in its atempts to combat climate change: “Rising populations and incomes are expected to double the global demand for meat and milk from 229 to 465 million tonnes and 580 […]
