Working with colleagues at National Taiwan University, PHE researcher Iddo Wernick coauthored a paper, published in the journal Sustainability, on environmental evaluation of supply chains.  The full citation is:

In a 2011 lecture at Iowa State University, Prof. Thomas Sinclair (North Carolina State) concluded from models and projections of yields of maize that maximum US corn yields would be in the neighborhood of 254 bushels per acre, that is, 16 metric tons per hectare.

Between 2009 and 2012 the national average corn yield has been 123 to 165 bushels per acre, about half Sinclair’s maximum of 254. Because Sinclair was speaking of maximum and the US Department of Agriculture reported actual yields for the vast US crop, the excess of Sinclair’s maximum over an actual average is not surprising and shows the opportunity for agronomist scientists is considerable.

Fortunately other reports, these of actual experience, show an even greater opportunity than that between Sinclair’s projected maximum and averages over the entire USA.

For 50 years the National Corn Growers Association has conducted a national contest, and in 2014 the NCGA reported seven participants beat 400 bushels per acre. One participant, Randy Dowdy of Valdosta, Georgia produced 503.

Thus, actual yields of corn show that farmers and suppliers have plenty of room to raise the US average yield from about 150 bushels per acre toward a maximum of 503.

And that performance that professors conclude impossible in theory can happen in practice.

PHE’s Iddo Wernick was named a Senior Fellow of the Breakthrough Institute for his work on the decoupling of resource use from the environment.  This continues our connection with the Institute, as PHE was recognized last year with the award of the Breakthrough Paradigm Prize to Jesse for his work on harnessing technology to lighten the human footprint.

PHE’s Mark Stoeckle co-authored the first large-scale study of an important urban wildlife denizen, the American cockroach (Periplaneta americana). This work demonstrates that genetically divergent lineages of American cockroach, likely from different parts of the globe, have emigrated to New York City where they now live together and interbreed–a lot like people!  Co-authors include Chris von Beeren and Daniel Kronauer in the Rockefeller Laboratory  of Insect Social Evolution; Joyce Xia, a Rockefeller Summer Program student; and Griffin Burke, a Bard College undergraduate.  The report appeared on February 6, 2015 in Nature’s open access journal Scientific Reports (link to article). This paper is the culmination of PHE’s National Cockroach Project  which enticed 85 citizen scientists to contribute nearly 300 cockroach specimens from mostly from New York City, but also from 16 other U.S. states and 6 countries. Thanks to all contributors!
