[Star Wars] Why are blockades so effective?

Senator Amidala commented in episode I that the people of Naboo were starving during the trade federation blockade or something like that.  She also mentioned the same thing in the *Clone Wars* during the battle of Ryloth, and sought to have aid sent to them.  Shouldn't a planet such as Naboo with plentiful natural resources be able to support itself?

The planet *could* support itself, but it probably just doesn't.  A lot of planets specialize their production for trade, and Naboo is one of those.  It's a very high tech planet with a very high standard of living. 

And agriculture isn't something you can just go out and start anytime.  Especially modern agriculture.  It takes a lot of time investment to get fields ready for crops, and then it takes even more time to grow and harvest those crops.  And that's assuming you have anyone trained in doing so.
