Drones can mitigate the effects of climate change on rivers

The aerial images taken by the drones facilitate the work of the experts, who can thus accurately identify the ideal locations for planting trees that keep the temperature of river water low.

The use of drones can help alleviate the effects of climate change on rivers by providing information on the planting of trees that avoid high temperatures, according to a study published by Marine Scotland, the marine affairs agency of the Scottish Government.

The research, carried out in collaboration with the University of Birmingham, was carried out in the face of concern about the consequences that rising temperatures are having on rivers, where it poses a danger to populations of salmon and brown trout.

The aerial images taken by the drones facilitate the work of the experts, who can thus accurately identify the ideal locations for planting trees that keep the temperature of river water low.

Controlled planting of vegetation has long been used as a method to keep rivers fresh, since, according to Marine Scotland, fish such as salmon and brown trout are “relatively intolerant” to high temperatures.

As part of the study, last summer, a drone equipped with a high-resolution camera was flying over the Dee River in Aberdeenshire (northeastern Scotland) to take aerial images, which were used to create a 3D map of the height of the trees along its banks.

The drones offer a low-cost study method that allows analyzing remote river areas in Scotland and the rest of the United Kingdom.

The information collected could be a great source of information to develop targeted plantations in places where trees would “be most effective in reducing the effects of climate change, ” according to Marine Scotland.
