    Olivia Lazard

    Visiting Scholar @
    Carnegie Europe

    Olivia Lazard is a visiting scholar at Carnegie Europe. Her research focuses on the geopolitics of climate, the transition ushered by climate change, and the risks of conflict and fragility associated to climate change and environmental collapse. 

    Olivia is an environmental peacemaking and mediation practitioner as well as a researcher. She has over twelve years of experience in the peacemaking sector at field and policy levels. With an original specialization in the political economy of conflicts, she has worked for various NGOs, the UN, the EU, and donor states in the Middle East, Latin America, Sub-Saharan and North Africa, and parts of Asia. In her fieldwork, her focus was to understand how globalization and the international political economy shaped patterns of violence and vulnerability patterns as well as formed new types of conflict systems that our international governance architecture has difficulty tackling with agility. It is also through fieldwork that she came to observe the ways in which the plundering of ecosystems feeds conflict systems across the world and contributes to climate disruptions. 

    Her research at the field level and on thematic issues has led to support the European External Action Service in integrating environmental peacemaking as part of their mediation toolkit. Prior to joining Carnegie Europe, Olivia set up her own consultancy firm, Peace in Design Consulting, which remains exclusively active in conflict and fragile zones.
