During the colonial era, seafarers used this geographical latitude as a navigational reference to establish sailing routes between ports. The line became an important point of reference for exploration and trade in southern oceans.
Communities along this line have adapted their way of life to the subtropical climate, with local farming practices and traditions shaping the landscape. The geographical zone continues to influence how people in these regions work and live today.
