Integrated Systems
The overall aim of this programme of work is to identify and demonstrate that management strategies to reduce GHG emissions intensity already exist and that they are practical and cost effective.
The programme includes two objectives:
- GHG emissions on sheep and beef farms (aligned to P21 programme)
- GHG emissions on dairy farms (aligned to Beef + Lamb NZ environment focused farm programme)
Principal Investigator
Dr Robyn Dynes, AgResearch

Sheep & Beef work to identifying strategies to reduce GHGs
01/09/16
The NZAGRC team are working with two B+LNZ monitor farms. The farms now have substantial, robust data and baseline farm systems models which demonstrate the extent to which the key management decisions and efficiency drivers impact on current...
Collaborative work investigating GHG emissions from dairy farms
