Unsupported Claims About Livestock and Climate Change in the Media

As a public health doctoral student, I have been taught the importance of communicating scientific information to the public, journalists, and policy makers in a careful manner, especially when dealing with complex issues.  Scientific research almost never provides clear answers, but as a scientist you should never make statements that overstep the conclusions of your work, even if it would make your life easier by simplifying the message you are trying to get across.  Describing questions that remain unanswered and limitations of studies is important.  While reading a news release last week regarding research on food animal production and greenhouse gas (GHG) emissions, I was suspicious that this “rule” was not being followed.

An air quality scientist at UC Davis, Professor Frank Mitloehner, has been in the press talking about implications of his research on livestock production and GHGs (here, here, and here).  He has been quoted as saying it is  “scientifically inaccurate” and a “distraction” to encourage a reduction in meat consumption as part of an effort to combat climate change.  Those are very strong statements, so I did a little digging to see if his research supports these claims.

Farming must change to feed the world

The world’s farmers must quickly switch to more sustainable and productive farming systems to grow the food needed by a swelling world population and respond to climate change, FAO’s top crops expert told an international farm congress in New Delhi today. 

In a keynote speech to 1,000 participants at the IVth World Congress on Conservation Agriculture (CA) in New Delhi, Shivaji Pandey, Director of FAO’s Plant Production and Protection Division, endorsed CA as an essential part of that change.

“The world has no alternative to pursuing Sustainable Crop Production Intensification to meet the growing food and feed demand, to alleviate poverty and to protect its natural resources. Conservation Agriculture is an essential element of that Intensification,” Pandey said. 

Conservation Agriculture is a farming system that does away with regular ploughing and tillage and promotes permanent soil cover and diversified crops rotation to ensure optimal soil health and productivity. Introduced some 25 years ago, it is now practiced on 100 million ha of land across the world. Read the complete article.
