where appropriate在这个句子中是充当定语成分,修饰adjustments and improvements .
这是一个省略用法,wherever appropriate 完整的说法是wherever it is appropriate .
整句分析是：
People（主语）
should make（谓语）
adjustments and improvements（宾语）
wherever appropriate（定语）
to ensure the optimal use of this form of travel.（目的状语）
不懂得再追问.
这是一个省略形式，完整说法：wherever it is appropriate to ensure...
状语从句中如果是it is + adj. + to do sth结构的时候，经常出现省略。
eg: I'll come to help if necessary / if possible.
