Sharing the aerosphere: Conflicts and potential solutions

Abstract

As our use of the aerosphere is increasing, so too are the conflicts that arise between our activities and those of aerial wildlife. As a result, numerous stakeholders are interested in monitoring, modelling and forecasting the aerial movements of animals in the context of anthropogenic impacts. Birds can pose a serious threat to aviation, resulting in delays, damage to aircraft, lost flight hours and even the loss of lives. Military and civil aviation use a range of measures to monitor the movements of birds and to try and reduce the risk of wildlife strikes. Increasingly, Unmanned Aerial Vehicles are sharing an already crowded airspace, although just how problematic this may become remains to be seen. The wind energy industry, another important stakeholder, may pose serious threats for aerial wildlife, due to collisions with turbines, or the extra energetic costs and risks entailed with avoiding wind farms. Similarly, other tall structures pose a threat for aerial wildlife. In this chapter, we describe the nature of these different conflicts and provide an overview of the factors that influence the risk associated with aerial movement. We also describe how movement is being studied to provide essential information for these different stakeholders and discuss several of the solutions that have been implemented to reduce potential conflicts. We conclude by discussing future perspectives for reducing conflicts by integrating different technologies for studying aerial movement, diverse approaches for modelling movement and working across international borders.
