Date of Conversation
Subject Matter Experts
Topics Discussed
January 23, 2012
Harry Baumes (USDA Office of the Chief Economist, Terry Coffelt (USDA ARS, Maricopa, AZ.  Performs agronomic studies of new crops), Terry Isbell (USDA ARS, Peoria, IL.  New crops research unit), Roy Scott (USDA ARS)

USDA research on jatropha.  USDA research has been limited because it is not frost tolerant, and ARS tends to focus on plants with potential for domestic development.
February 2, 2012
Terry Coffelt (USDA ARS, Maricopa, AZ), Dan Parfitt (Horticulturist at UC Davis.  Researched U.S. jatropha cultivation under funding by Chevron)
Discussed current efforts to grow jatropha around the world, research at UC-Davis and in Hawaii, the current state of knowledge, and data limitations.
February 15, 2012
Wagner Vendrame (Tropical Research & Education Center.  Horticulturist at University of Florida), Terry Coffelt (USDA ARS, Maricopa, AZ)

Jatropha research at University of Florida.  Limited data on jatropha globally.  Relatively minor frost problems in Florida so far.
February 15, 2012
Terry Coffelt (USDA ARS, Maricopa, AZ), Jaime Barton ( HARC), Bob Osgood (HARC, Director), Richard Oguchi and Joshua Knight (University of Hawaii)
Jatropha research in Hawaii.  Lack of success globally growing jatropha on marginal lands with low inputs.
February 15, 2012
Rob Bailis (Yale School of Forestry)

LCA research on jatropha.  Current efforts to grow jatropha around the world.  Data sources for jatropha production.
January 8, 2013
Bruce Babcock (Iowa State University)
Analysis of jatropha using the FAPRI-CARD model
