Both statements are correct.

Buchanan's vision and his priorities were different from those of the local inhabitants: his assessment of what was necessary was shaped by the commercial concerns of the Company and modern Western notions of what constituted progress. He was inevitably critical of the lifestyles of forest dwellers and felt that forests had to be turned into agricultural lands.
