How reindeer help fight climate change

In the northern region of Lapland, reindeer are playing a crucial role in combating climate change. By consuming shrubs, these animals enhance the reflectivity of snow and ice, a process known as the albedo effect. This is significant as it prevents the absorption of heat, thereby reducing the rate of melting and maintaining cooler temperatures.

Tiia Jeremejeff, a reindeer herder of Sami descent, is responsible for the care and feeding of her family's herd. The task is challenging, particularly during the winter months when temperatures drop to -15C. However, she understands the importance of her role. Reindeer herding is not only a source of income for her family but also an integral part of their cultural heritage.

Recent studies suggest that reindeer may have a profound impact on preserving the entire ecosystem, including the snow cover, the open forest, and even the cold winter climate. The Arctic region, where Lapland is located, is experiencing a warming rate four times faster than the rest of the planet. However, reindeer may help mitigate some of these effects by grazing and trampling on plants, thereby preventing excessive growth and heat trapping. This discovery has significant implications for the indigenous communities in the Arctic and the global fight against climate change.
