Scientists from developing countries are in Palmerston North for a training course on measuring methane emissions from forage-fed farm animals.
Nine agricultural science technicians from South East Asia and South America are at New Zealand's Agricultural Greenhouse Gas Research Centre for the three week course.
They are there to learn latest techniques in measuring the methane emissions of ruminants, from operating methane measuring chambers to using tracing gasses.
Research centre director Dr Harry Clark said methane is a potent greenhouse gas and that if the world is to tackle climate change it needs to address agricultural emissions.
He said the training course is part of a larger global effort to correctly calculate methane emissions.
