This report aims to provide a comprehensive overview of how peacekeeping operations affect and are affected by natural resources and environmental conditions. The report is divided into two main parts. Part 1 reviews the environmental management of peacekeeping operations and showcases good practices, technologies and behaviours that have already been adopted. Part 2 examines the role that peacekeeping operations have played in stabilizing countries where violent conflicts have been financed by natural resources – including diamonds, gold, timber and oil – or driven by grievances over their ownership, access and control.
