I think the correct term in english is ICS (Industrial Control Systems). Sorry, not a native speaker :P

How about automation? I used to work in an automation company (as a dev), and the work the engineers did seemed to fit your profile pretty well: Electrical engineering, project management, customer support and some dev to put it all together. I'm guessing the roles will be more distinct in larger companies (we were about 60 people total), but ICS is a nice middle ground between EE and programming.

Yes, i found several people making that claim (or similar). Couldn't find any hard data to back it up, though (although i didn't search too hard since i'm at work :P)

Ha, no, you're right. Don't remember were i first heard it, but looking for the sources now, it seems that small farms are more productive in poor countries, but less productive than industrial farms in developed nations. However, the source i found for that [0] doesn't mention what techniques are used, and seems to only focus on size. So now i'm curious if there is reliable data looking at differences in yield between farming techniques? (e.g. industrial/chemical vs organic vs permaculture)

Not really. Small-scale sustainable farms produce more food per hectare than industrial farming. However, they are usually less profitable, since they need more manpower per hectare. Efficiency in terms of money earned is not the same as efficiency in terms of food produced, and with a growing population and a diminishing area of arable land, one seems more critical than the other, especially when you consider that industrial farming tends to destroy topsoil and emits quite a bit of CO2, whereas small-scale sustainable farming usually does the opposite.
