Climate variability and extremes are associated with increased prevalence of conflict, with more consistent evidence for low- intensity organised violence than for major armed conflict . Compared with other socioeconomic drivers, the link is relatively weak  and conditional on high population size, low socioeconomic development, high political marginalisation and high agricultural dependence . Literature also suggests a larger climate-related influence on the dynamics of conflict than on the likelihood of initial conflict outbreak . There is insufficient evidence at present to attribute armed conflict to climate change.
