英文句子翻譯，知道每個字意思，但不能解讀

Meaning of:
[some water experts are now demanding that existing infrastructure be used in smarter ways rather than building new facilities, which is increasingly considered the option of last, not first, resort.]


My opinion:
The relative pronoun "which", in this sentence, refers to the noun phrase "building new facilities".

The compound noun "last resort" means the "last possible course of action". By contrast, "first resort" means the action one would consider taking first.

There are two options given in this sentence, one option is to build new facilities as the first resort, the other option is to build new facilities as the last resort.

Therefore, the whole sentence can be broken down into 3 sentences:
1. Some water expers are now demanding that existing infrastructure be used in smarter ways rather than building new facilities..
2. Building new facilities is increasingly not considered the option of first resort.
3. Building new facilities is increasingly considered the option of last resort.

Once we take away the repetition, the 3 sentences can be reconstructed to become the original sentence.

本來各答各的，互不相干。但不去指出與事實或真理完全相反的答案，亦是對知識+不負貴任的行為，所以不得不說：
[Last resort] 解 [用盡了其它辦法，最後迫不得已才會採用的辨法]。
絕對不是如 002 所說，解 [最終的解決辦法]。

001 is absolutely correct.
some water experts are now demanding (A) rather than (B), which is increasingly considered the option of last, not first, resort.
which -----> B i.e. B is increasingly considered the option of last resort (not first resort.)

thank you for you answer~
答案夠詳盡！
贊！

which is increasingly considered the option of last , not first, resort.

它 日益被視為最終的(解決辦法),並非初步的解決辦法。

Which 是指 existing infrastructure
be used in smarter ways rather than building new facilities
