What is 量 referring to in this sentence?


This is the first sentence of the
[article](http://www3.nhk.or.jp/news/easy/k10010868241000/k10010868241000.html):

> ヨーロッパでは日本料理の人気が高くて、だしを作るためのかつお節を使う **量** も増えています  
>  Japanese cuisine is popular in Europe and the **amount** using katsuobushi
> to make dashi is increasing.

**Amount** of what? Is 量 referring to the number countries in Europe that use
katsuobushi? The number of people in Europe that use it? Or have I totally
mis-parsed it?

My other thought was that だしを作るための might modify 量 rather than かつお節. So we have
だしを作るための量も増えています "The amount (of katsuobushi) for making dashi is increasing",
and かつお節を使う量も増えています. I couldn't make much sense out of this part so I
discounted it.

Is there any difference if I say:

> だしを作るため **に** かつお節を使う量も増えています

so that だしを作るために adverbially modifies 使う?




だしを作るためのかつお節を使う量 is "how much [European people] consume _katsuobushi_ for
making _dashi_." So this 量 refers to the amount of かつお節.

Consider the following "original" Japanese sentence:

> ヨーロッパの人々はだしを作るためのかつお節を **{たくさん|100グラム}** 使う。  
>  European people consume {a lot of | 100 g of} _katsuobushi_ for making
> _dashi_.

Note that the amount is [expressed
_adverbially_](https://japanese.stackexchange.com/a/42184/5010) as usual in
Japanese. だしを作るための modifies かつお節, not 量. Let's omit the obvious subject:

> だしを作るためのかつお節を **{たくさん|100グラム}** 使う。

Replace the bold part with 量 and pull it out to the end to form a relative
clause:

> だしを作るためのかつお節を使う量 …①

* * *

You can express the same thing using the passive voice. Starting from this
sentence:

> （ヨーロッパでは、）だしを作るためのかつお節がたくさん使われる。  
>  (In Europe,) a lot of _katsuobushi_ for making _dashi_ is consumed.

By pulling out the たくさん part, you get this noun phrase:

> だしを作るためのかつお節が使われる量 …②  
>  how much _katsuobushi_ for making _dashi_ is consumed

The noun phrases ① and ② say the same thing. The only difference is that ① is
active and ② is passive.

Here are some similar examples of ["adverbial-head" relative
clauses](https://japanese.stackexchange.com/q/39551/5010):

>   * 13時に昼食を食べた。 I ate lunch at 13.  
>  → 昼食を食べた時間 the time when I ate lunch
>   * 東京でその映画を見た。 I watched the movie in Tokyo.  
>  → その映画を見た場所 the place where I watched the movie
>

Obviously you don't eat 時間.

Lastly, in this example, you can change だしを作るための (modifying the following
noun) to だしを作るために (modifying the following verb) without altering the meaning
of the sentence.
