I was only able to catch some of the live stream of the 2011 Global Agricultural Productivity Report. I've had word via @Harvest2050 that they will be posting the recording at some point. I'll be sure to post it. If you'd like to read the full report, you can find on the Global Harvest Initiative website.
Some of the graphics in the report are pretty interesting:
|Most of the population growth will happen in
Sub-Saharan Africa and Asia.
|The importance of agricultural trade is going to increase as
the distribution of the world's population relative to the
arable land is going to be imbalanced.
