LingakuLingaku[noun] + が見られる [noun] + がみられる
が見られる says that something can be seen somewhere, or is found or observed there. The thing seen takes が, and the place takes で, では or に. Nobody in particular does the seeing.
With a sight – a bird, a festival, a view, a film – 見られる is the potential of みる見る: the chance to see it is there. In casual speech this sense is often みれる見れる.
In reports, the news and academic writing, がみられる states what has been found: a trend, a change, a difference, an improvement. Here it is "is observed", not "can see", it is often written in kana, and it never becomes 見れる.
