Conflicts between human activities and wildlife are an increasing problem, and in many parts of the world damage caused by wildlife creates significant economic challenges to human communities. Methods for reducing humanwildlife conflicts are either ineffective, time consuming or costly. Both lethal and non-lethal techniques are used for reduction of human-wildlife conflicts. However, the use of lethal methods is often controversial, as there is a public desire to co-exist with wildlife. This thesis is focused on human-wildlife conflicts in agriculture. The research has been driven by two very different conflicts between wildlife and agricultural activities, namely the problems with large flocks of birds in agricultural fields and wildlife mortality during mowing operations. The scientific contributions of this Ph.D. thesis focus on how sensor technologies and pattern recognition methods can be applied in the design of solutions for the reduction of human-wildlife conflicts in agriculture and thereby contribute to more ethical and efficient wildlife damage management. The result is a collection of contributions to the design of pattern recognition and signal processing algorithms to enable the use of smart sensing in the solution for human-wildlife conflicts. The achieved results are a significant step towards a more efficient sensor based solutions for wildlife-friendly farming and reduction of human-wildlife conflicts within agriculture. I would like to thank my supervisor Henrik Karstoft from the Department of Engineering, University of Aarhus, for providing valuable feedback and motivation during my Ph.D. project. It has been a great pleasure to work with Henrik, who has always left the door open for theoretical discussions and personal guidance. I would also like to thank my co-supervisor Ole Green from the Department of Engineering, University of Aarhus, for giving me the opportunity and challenge of pursuing a Ph.D. degree. Both Henrik and Ole have been an inspiration to constantly perform well during the Ph.D. project. For this, I thank you. Ole Roland Therkildsen has also been an important part of this Ph.D. project. His dedication to research within human-wildlife conflicts and his skills within scientific writing have been very rewarding. I would also like to thank Rasmus Nyholm Jørgensen who has helped me during my work regarding wildlife-friendly farming. His constant flow of new ideas and critical questions have been an eye-opener for my approach to this research. I would like to thank my colleagues Morten Stigaard Laursen, Thomas Jensen, Martin Christiansen and Peter Ahrendt for their contributions to technical discussion, feedback and motivational working environment. I have enjoyed discussing my work with you, and I am thankful for your patience during this. I would like to thank James H. McClellan for giving me the opportunity to visit Georgia Institute of Technology during my Ph.D. project. This experience was rewarding both personally and professionally. I would also like to thank my parents J...
