This publication provides an overview of how we may be able to use compounds that suppress an animal's methanogen population effectively without causing unwanted side effects in their health, welfare or production. It covers some of the...
This publication is a guide to New Zealand's way of funding greenhouse gas research in New Zealand including ways the funds work in partnership to grow New Zealand's understanding and contribution to real solutions to tackle climate change.
Agricultural greenhouse gas (GHG) mitigation research funding comes from multiple sources. The growing appreciation of the need to tackle climate change, and the diversity of the challenges that agricultural GHGs present, means there are a range...
This publication provides an overview of how we can map the amount of carbon stored in New Zealand soils.
Other methane measurement techniques provide estimates of emissions from individual animals. This raises the question whether the animals that have been measured are representative of average emissions coming from an entire herd over long...
Farms are complex operations, and changes in one part of the system can affect production and emissions in other parts. It is crucial to understand how individual options to reduce emissions fit into the overall farm system and farming practice:...
Nitrification inhibitors slow the conversion of ammonium (NH4+), deposited into the soil in the form of urine, to nitrate (NO3), which leaches into waterways. Nitrous oxide (N2O) is released into the atmosphere as part of this process. DCD...
Widespread adoption of an effective vaccine/inhibitor package, together with the breeding of low methane-emitting animals, could deliver large emissions reductions – substantially larger than all other mitigation options combined. If...
HOW THEY WORKCommonly, these are a sheepsized transparent polycarbonate box suspended above a race. When a sheep walks into the race, the chamber is lowered over it and the sheep is held inside for about 30 minutes. Air samples are taken during...
New options for reducing total emissions may become available in the next few years, based on evidence from laboratory studies and small-scale animal trials. The critical challenge for those options is to commercialise them and ensure they are...
Some key research supported by the NZAGRC and PGgRc is now at, or approaching, proof of concept stage; other research is still developing fundamental understanding to identify future options. Results from laboratory or experimental settings so far...
Options to further enhance production efficiency New Zealand already operates a highly efficient and productive pastoral system. Over the past 20 years, farmers have steadily improved feed and nutrition, animal genetics, pasture management, and...
This publication provides an overview of the impact of gibberellins on grazed grasslands and the potential for gibberellins to mitigate farm nitrous oxide emissions.
This publication provides an overview of how the NZAGRC is working with other organisations to understand what efficiencies can be gained on New Zealand's sheep and beef farms.
This publication provides an overview of what soil carbon is, how we can measure and determine the changes over time and what New Zealand's current soil carbon levels are. this publication was produced in collaboration with the University of...
This publication provides an overview of the particular measurement techniques used to provide us with more information on New Zealand's GHG emissions.
This publication provides an overview of the GHG mitigation work been undertaken in New Zealand.
Reducing New Zealand's agricultural greenhouse gas emissions without sacrificing production gains is what we are working to achieve through the NZAGRC-PGgRc science programme. Find out more about New Zealand's...
Agriculture emits a range of greenhouse gases. Evaluating the effectiveness of mitigation strategies requires a way to compare the contribution of individual gases to overall emissions. This is usually done by converting emissions of methane and...
Climate change presents multiple challenges to New Zealand. Some are direct - such as climatic impacts on domestic agricultural production, or domestic climate policies - but further, indirect impacts could come from overseas, via trade, such as...
There is robust scientific evidence that the climate is changing, and that most of the warming observed over the past 50 years is due to increasing greenhouse gas concentrations from human activities. This fact sheet summarises why, and how,...
