Environmental Peacebuilding: Yesterday, Today, and Tomorrow

The field of environmental peacebuilding emerged as a counter to the idea that violent conflict was an inevitable byproduct of environmental change. Two decades ago, my colleague Geoffrey Dabelko and I published a book, Environmental Peacemaking, sketching the argument that ecological interdependencies could be instrumentalized as a force for peace (Conca & Dabelko, 2002). Other early works from this period focused on the peace opportunities in biodiversity conservation (Matthew et al., 2002) and transboundary protected areas (Brock, 1991; Ali, 2007). Since that time, a substantial community of research and practice has emerged around these ideas. In this essay I discuss the origins of the field, sketch some of its core concepts, and look to the future, pointing to some key challenges ahead

Solar geoengineering: The case for an international non-use agreement

Solar geoengineering is gaining prominence in climate change debates as an issue worth studying; for some it is even a potential future policy option. We argue here against this increasing normalization of solar geoengineering as a speculative part of the climate policy portfolio. We contend, in particular, that solar geoengineering at planetary scale is not governable in a globally inclusive and just manner within the current international political system. We therefore call upon governments and the United Nations to take immediate and effective political control over the development of solar geoengineering technologies.Specifically, we advocate for an International Non-Use Agreement on Solar Geoengineering and outline the core elements of this proposal
