Global Research Alliance on Agricultural Greenhouse Gases
New Zealand is a member of the Global Research Alliance on agricultural greenhouse gas emissions.
What is the Global Research Alliance?
The Mission of the Global Research Alliance on Agricultural Greenhouse Gases (GRA)is to bring countries together to find ways to grow more food without growing greenhouse gas emissions. It was launched in December 2009.
How is New Zealand involved in the GRA?
New Zealand is a founding member, the current GRA Secretariat, is one of the Co-Chairs of the Livestock Research Group, and was GRA Council Chair (2011-2012).
The New Zealand Government committed $45 million to the work of the GRA in 2010 and in 2016 announced a further 20 million out to June 2020 to fund research in the area of greenhouse gas emissions mitigation in pasture based temporal livestock systems.
New Zealand is represented in the GRA by the Ministry for Primary Industries (MPI), working closely with the environment and climate change groups from the Ministry of Foreign Affairs and Trade (MFAT) and the Ministry for the Environment (MfE). MPI contracts the NZAGRC to manage New Zealand’s involvement in the Livestock Research Group and New Zealand’s GRA science research activities.
What is the GRA Livestock Research Group?
The Livestock Research Group (LRG) is focused on reducing the emissions intensity of livestock production systems and increasing the quantity of carbon stored in soils supporting those systems.
The LRG is co-chaired by NZAGRC Director, Dr Harry Clark and Dr Martin Scholten, Wageningen UR, Netherlands.
The LRG Vision is to:
- Increase agriculture production with lower emissions
- Improve global cooperation in research & technology
- Work with farmers and partners to provide knowledge

Searching deep within for methane battlers
by NZAGRC Team
The role of microbes in producing methane is being studied by an Irish scientist, writes Jarrod Booker.
While science is helping us discover vast new worlds beyond our own, the worlds explored by Sinead Leahy are far too small to be seen by the naked eye.
This world of microbes – tiny bugs such as bacteria that could fit by the millions in the eye of a needle – are all around us and keep the planet functioning. For Leahy, a senior scientist at AgResearch, her focus over the last decade has been on the complex world of microbes in the stomachs of ruminants like cows and sheep – and the huge implications these tiny single-cell organisms have for both New Zealand's economy and environment.
"We know so little about this microbial world, because people don't see it and they don't realise how important it is to us in New Zealand. It's only recently that we have started to get DNA sequencing technologies that allow us to study these worlds with new insight," Leahy says.
"The microbes in the sheep or cow's rumen (a chamber of the stomach) powers the animal by allowing it to break down the grass it eats, and gives us the products like milk, meat and wool that New Zealand sells to the world."
It is not only the size of the microbes in the rumen that makes them difficult to identify and study, it's also the environment they exist in – without oxygen – and the highly complex roles they play, and how they interact with each other.
Irish-born and raised Leahy, alongside her colleagues in rumen microbiology at AgResearch, has spent the last decade in New Zealand learning more about these microbes, to help farmers produce healthier, more productive animals and lift New Zealand's economy. But the potential is also huge when it comes to methane gas produced by the animals, given that methane is the largest contributor to New Zealand's greenhouse gas emissions.
As scientists at AgResearch and elsewhere press to find ways to reduce the amount of methane produced – including potential for a methane vaccine – Leahy says the role of microbes here is crucial. By learning more about the microbes that are part of the process of producing the methane in the animals, there is the opportunity to find new ways to address it.
Leahy was part of an international project led out of AgResearch, called Hungate1000, in which the genomes of hundreds of different microbes from ruminants from around the world were mapped to provide an important resource for researchers globally.
While New Zealand should be proud of its rugby players and rowers, they should also recognise that in areas like rumen microbiology, New Zealand is a world leader, she says.
Though she and her Irish-born husband are now also New Zealand citizens, along with their two New Zealand-born children, there is no question where her loyalties lie when it comes to the rugby arena. She looks back on the famous Irish victory over the All Blacks in Chicago last year as "one of the greatest days of my life".
"It was a long time coming. After all the pain of the last 10 years, I finally got to come to work in my Ireland jersey and lord it over everyone for a change."
Leahy, 38, was one of nine children growing up in the Irish township of Bilboa – she had more siblings than there were pupils in her primary school class. Her grandfather's small farm nearby had her exposed early to rural life – "we grew up with milk straight from the cow".
Her family was very strong in mathematics, and she remembers telling them at a young age she was going to be a researcher.
"I remember in primary school a teacher turning water with different colours with dye. It basically set me on the path from there."
After completing her PhD in Cork, Leahy arrived in New Zealand in 2006, for what she told family and friends was part of a two year adventure around the world. After landing the job at AgResearch, and becoming attached to the work, her team, and the lifestyle, she decided to stay.
"I think my family always knew I was going to go off and see the world and do something more."
While retaining her position at AgResearch, Leahy has recently taken up a new role of International Capability and Training Co-ordinator for the Government-funded New Zealand Agricultural Greenhouse Gas Research Centre (NZAGRC).
The role will support the goals of the Global Research Alliance on Agricultural Greenhouse Gases, an initiative supported by the New Zealand Government to increase collaboration between countries to reduce the emissions intensity of food production. One of the objectives of Leahy's role is to engage scientists and policy audiences in the developing world on why lowering agricultural greenhouse gas emissions intensity (the emissions per kilogram of meat, milk, vegetables or grains) is important for their agricultural production.
"It's something I haven't done before, working on that interface between governments and the science, and the area of developing policy," Leahy says.
"It's vital to have that policy in place if you want to make real change, and for that policy to be built on quality science."
