- Assess the impact of climate change on reindeer husbandry
- Study the variation of winter conditions
- Scientific and pratical knowledge combined
- Dynamic optimization
Wild and semi-domesticated reindeer are one of the key species in Arctic and subarctic areas, and reindeer husbandry is an integral part of the social and economic life of many northern indigenous and local communities. Reindeer population dynamics are closely tied to winter conditions.
By combining a state-of-the-art bioeconomic model and practitioner knowledge, the authors aim at studying how the variation of winter conditions and potential increase of this variation due to climate change affect the economic sustainability of reindeer husbandry.
Artelys Knitro is leveraged to conduct the analysis, allowing to conclude that the increase of variation in winter conditions will negatively affect the reindeer herding economy, even if the harshness of winter conditions during difficult winters does not change. In addition, the study shows that scientific and practical knowledge can be combined and mutual validate each other, offering compatible insight, ideas, and understanding that can be accepted by researchers and local communities.
