Food waste, soil erosion, deforestation and, yes, methane from cows feature in a major Intergovernmental Panel on Climate ChangeÂ (IPCC) report on land. Farmers emerge not only as contributors to climate change, but some of its most significantÂ victims.
Farming needs to change to help save the climate -Â but if other emitters donâ€™t slash their carbon outputs to save the climate and, consequently, farming, our food supply will be in trouble, writes Eloise Gibson in New Zealand based Newsroom.
The IPCCâ€™sÂ Special Report on Climate Change and LandÂ is the first time the global network of scientists has looked at land use and climate change in the broadestÂ sense, and the authors haveÂ warned that food security willÂ suffer if global warming overshoots 1.5C or, especially, 2C.
The report makes clear that much of the onus is on industrial, transport and other emitters to urgently cut greenhouse emissions to give food growers the friendly climate theyâ€™ll need to feed a growing and increasingly affluent global population.
Agriculture itself is in a tricky position: its existence as an industry is non-negotiable if people are going to continue to eat.
But the way people use land currently is responsible for about 23 percent of global emissions, counting both deforestation and farming emissions. ThatÂ figure is higher -Â up to 37 percent -Â if emissions from the whole food system are counted.
Now that worldÂ governments have signed off the IPCC report, it will be used in future discussion on government climate action. The report is sprinkled with actions that could be taken now to help the climate, and land.
