This incisive Research Handbook addresses the growing recognition within the international law community that natural resource governance and environmental protection are crucial aspects of peace processes, both as a security imperative and as an opportunity for peacebuilding. Examining the impact of international normative and institutional frameworks on environmental peacebuilding, this Research Handbook features contributions from distinguished experts and global case studies on integrated legal approaches to the governance of natural resources. Chapters examine the role of international legal obligations on fair and equitable benefit-sharing in environmental protection, the contribution of the UN and other international institutions to environmental peacebuilding, and the nexus between access to environmental services and peacebuilding efforts. The compelling conclusion explores contemporary approaches for improving the inclusivity of environmental peacebuilding, considering the role of gender and indigenous peoples’ perspectives. The Research Handbook on International Law and Environmental Peacebuilding will be crucial reading for students and scholars in environmental law, environmental politics and policy, peace and security studies and public international law. Its comprehensive treatment will also be beneficial to policymakers in international environmental and peacebuilding organizations.
