What does reciprocity mean?

Question

It should be said that the view from the Hurtigruten is very slow. As in: very, very slow. Despite once being billed as the “coastal express,” the ferry actually travels at a maximum speed of around 15 knots, which is about the speed of a brisk bicycle ride. So you really have time to linger on every skerry, every shoal, every wind-blown bluff.
[Scroll 40% down the website] The slowness of the Hurtigruten forced all of us into a relationship of reciprocity with the landscape. Despite being only 150,000 square miles (about the size of Montana), the country boasts one of the most undulatory coastlines in the world, measuring an astonishing 64,000 miles (by comparison, the entire United States coastline measures 95,471 miles).

How can a traveller and the landscape be related by reciprocity?

Answer 1

Basically a two way beneficial relationship between man and the environment.

See this definition - reciprocity sense 1:

1) reciprocal state or relationship; mutual action, dependence, etc.

The ferry goes slow so you can appreciate the landscape. Then presumably the coastal area would benefit as fewer people would want to spoil the natural environment.
