Our guest for this episode is Professor Rick Roush, Dean of Land and Food Resources. Rick Roush!|s career spans research, teaching, regulatory, and administrative appointments in both the US and Australia. Rick!|s main efforts for the last 30 years have been to develop integrated pest management solutions and he has also published extensively pesticide resistance management and on biological control of insects, mites and weeds. Roush earned a PhD at the University of California, Berkeley, and has worked at Texas A&M, Mississippi State, Cornell and Adelaide Universities.

From 1998 through 2002, Roush served as Director of the national Australian Cooperative Research Centre (CRC) for Weed Management based at the University of Adelaide, and coordinated weed management research and extension on crops and natural ecosystems at 19 state, federal, industry, and university organizations across Australia. This included leading the CRC to its renewal in 2001 for another 7 years with $18 million in federal grants.

"... every transgenic crop, every new variety of a transgenic crop gets scrutinized by regulatory authorities in several countries, and usually in each country there will be at least 20 scientists looking at the data sets that are available." - Prof Rick Roush

GM Supporters argue that

GM Supporters argue that genetic engineering will save the growing world population from starvation, because the genetically modified plants can exist on less fertile soils and provide a rich harvest, and therefore long kept. But environmentalists fear that genetically modified forms may accidentally enter into the wild, which would lead to catastrophic changes in ecosystems.

GM Crops

Good day,
Thank you for a great podcast, I have only recently discovered it and enjoy it very much.
As an organic gardener, I was very interested in this topic, and
although I understand your function is not to debate issues, I would
love to hear an organic expert give his/her option on this subject.
There are many issues that were not discussed.
Thanks again for a great Podcast.
Kind regards
Marilyn O'Brien

Read Tomorrow's Table

I suggest that you read Tomorrow's Table, by Pam Ronald and Raoul Adamchak. One is a rice geneticist, and the other is an organic farmer, and the are married to each other - and they think genetic engineering and organic agriculture can be, too.
