Leaving Paris ‘not in red meat sector’s interests’
Beef and Lamb New Zealand (B+LNZ) chair Kate Acland says it’s not in red meat farmers’ interests to leave the Paris Agreement on climate change.
Challenges and opportunities exist for agriculture in limiting global warming to 2oC, says a leading New Zealand agricultural greenhouse gas researcher.
Dr Andy Reisinger, deputy director of the New Zealand Agricultural Greenhouse Gas Research Centre, and a lead author of the 5th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), spoke last month at the Australian Agricultural and Resource Economics Society’s (AARES) conference in Rotorua.
He says the IPCC concluded recently that emissions of carbon dioxide need to be reduced to zero by 2100 to limit global warming to 2oC, a goal “accepted by most governments around the world, and an enormous challenge”.
“Reducing greenhouse gas emissions from agriculture globally can make an important contribution to the goal of limiting warming to 2oC and would lower the global costs of achieving this goal.”
But there are difficulties for New Zealand, where almost half of total greenhouse gas emissions come from agriculture.
Raising awareness of the global potential for livestock research to reduce emissions is challenging because for many other countries, livestock contribute only a small percentage of total greenhouse gas emissions, he notes.
“New Zealand’s domestic research programme, together with its support for the Global Research Alliance for Agricultural Greenhouse Gases, is trying to increase global engagement through research collaboration and position New Zealand to lead global efforts in this area.
“Key options on the global scale for reducing agricultural emissions are increasing productivity and efficiency of food production, developing new technologies to reduce emissions without compromising food production, and managing demand by reducing food waste and influencing dietary choices away from emissions-intensive food products.”
Reisinger says that emissions per unit of livestock product have declined consistently for 20 years in New Zealand, demonstrating that improvements in productivity and efficiency can make a difference. But options are limited for New Zealand to reduce absolute emissions from agriculture within current overall agricultural growth targets, hence new technologies are needed.
“Absolute emissions from agriculture in New Zealand have increased due to increased overall production, mainly from expansion of dairy farms, in response to global demand. Most of New Zealand’s livestock products are exported. Soil carbon stores are high in New Zealand, which limits the scope for offsetting emissions by increasing soil carbon.”
Rural retailer Farmlands has launched a new casual clothing range available across 42 stores nationwide and through its online store.
Federated Farmers says the health and safety changes announced this week by the Government represent the start of overdue reforms.
The Government is calling on rural New Zealanders to share their views on proposed regulations designed to improve the management of farm plastic waste.
For many urban New Zealanders, stepping into Pāmu’s Pinta dairy farm near Taupo last month was the first time they had had the chance to experience farm life up close.
