Researchers are on the hunt for a cow that produces less methane, one of the major contributors to climate change. If and when those green genes can be easily isolated, they could be spread throughout global cattle populations.
We can shrink the carbon footprint of livestock, but we need to properly measure their emissions first. Opinion piece written by Polly Ericksen.
California has a lot of dairy cows, and all that belching and farting and decomposing poop accounts for 5 percent of the state’s total greenhouse gas output. If you want radical emissions cuts, you gotta go for the belches.
Using the state-of-the-art laboratory established in 2015 in Nairobi called the Mazingira Center, scientists are measuring greenhouse gas emissions from agriculture in Africa, key to improving the accuracy of emissions data for both national reporting and mitigation. Already, scientists found that Tier 1 emission factors established by the Intergovernmental Panel on Climate Change (IPCC) overestimate both methane and nitrous oxide emissions from cattle excreta, given typical smallhoder practices in Eastern Africa.
The following is an unusually sane and well communicated multimedia primer on the sustainability of the global food system. Food Matters, republished here in full with permission, is published by the Institute on the Environment at the University of Minnesota.
On 3–4 May 2016, policymakers from climate change departments of Kenya and Uganda met with scientists from CCAFS and ILRI for discussions on development of regional greenhouse gas inventories.
Peter Janssen of AgResearch, New Zealand’s main farming-science institute, is looking for ways to reduce the amount of methane the country’s animals burp up.
