'landscape-affected' originates from the combination of 'landscape' and 'affected', where 'landscape' refers to the visible features of an area of land, and 'affected' means influenced or changed by something.

The term 'landscape' comes from the Dutch word 'landschap', and 'affected' is derived from the Latin word 'afficere', meaning 'to influence'.

Initially, 'affected' meant 'to have an effect on', and this meaning has largely remained the same in modern usage.
