Translation:Without a levee one does not have a polder.
That's a great point, and explains why agricultural productivity in terms of crop yields has historically been significantly higher in the Netherlands than anywhere else (and still is). For example, wheat yield per hectare in 2000 was less than three tonnes in the United States, and over eight tonnes in the Netherlands.
This also partially explains the Dutch Golden Age, at a time when agriculture was still the most fundamental sector of the economy because it basically was the energy industry prior to the industrial revolution. And of course, the Dutch were also ahead of the game in developing non-muscle powered (human and animal labor) forms of energy with windmills for mechanical energy and the combustion of peat for heat.
In that sense you're right. They don't do anything =D.
Yes there are villages in them. But I think this discussion has gone too far. It isn't a geography course. I'm not sure you really understand what a polder is =P. It's just a piece of land reclaimed from sea, lake or marshes. If you want to know more, just google it, do some research. I would also suggest visiting the Netherlands. They're all over the place =).
Land has many functions. Besides that, polders are man made, as I understand it, which means they aren't just built to exist--they must serve some purpose?
You say agriculture. Do they grow crops on them that need lots of water? Do they need more land so they extend it out with polders? Can you walk on a polder? Do polders eventually dry out and turn into more land?
I don't think you understand what polders are. Polders are just pieces of land that used to be underwater but are now dry land. Most polders are used for agriculture so there are farms and roads for the farmers, some are crossed by a highway, so yes you can go there. A few have villages or cities on them.
Thanks! I was referring to these, which looks like not all polders are dry land?
