There is a widening consensus that the impacts of climate change will change the terrain of conflict. This article begins by noting IPCC reports, along with governmental reports issued by US, German, NGO and IO sources.
The authors then review the academic literature on climate change and conflict. They find it generally wanting, as many sources are not peer-reviewed and the total scope of work is sparse. Additionally, much of the literature that does exist is contentious: do nations cooperate around water resource issues, or come to blows?
The authors highlight five articles that help to form a backbone of the study of the relationship between climate change and conflict.
"This literature outlines several possible causal chains from climate change to conflict. The starting-point for most of these is that climate change results in a reduction of essential resources for livelihood, such as food or water, which can have one of two consequences: those affected by the increasing scarcity may start fighting over the remaining resources. Alternatively, people may be forced to leave the area, adding to the number of international refugees or internally displaced persons. Fleeing environmental destruction is at the outset a less violent response to adverse conditions than armed conflict or genocide. But when the migrants encroach on the territory of other people who may also be resource-constrained, the potential for violence arises" (631).
Drivers from climate change of conflict include changes in the availability of resources (food, fuel or water), forced migration, dramatic weather events, moves away from fossil fuels quickly, thus radically changing the price of oil and impacting dependent countries, or reduced economic output as a result of attempts to reduce carbon emissions.
They end with a focus on five points to improve analysis of this relationship: 1. conflict models and climate change models need to be synthesized; 2. what kinds of violence do we expect to emerge from climate change?; 3. there needs to be an accounting of both the positive and negative impacts of climate change; 4. the impacts of climate change need to be increasingly disaggregated; and 5. consequences should not focus on rich countries alone, but the globe.
