Increases in food prices due to reduced agricultural production and global food price shocks are associated with conflict risk and represent a key pathway linking climate variability and conflict . Increases in food prices are associated with civil unrest in urban areas among populations unable to afford or produce their own food and in rural populations due to changes in availability of agricultural employment with shifting commodity prices . Under such conditions, locally specific grievances, hunger and social inequalities can initiate or exacerbate conflicts. Food price volatility in general is not associated with violence, but sudden food price hikes have been linked to civil unrest in some circumstances . In urban settings in Kenya, Koren et al.  found an association between food and water insecurity that is mutually reinforcing and associated with social unrest . Analysing the global food riots in 2007/2008 and 2011, Heslin  stresses the role of local politics and pre-existing grievances in determining whether people mobilise around food insecurity .
