Gender is a traditionally under-researched dimension in scholarship on climate and security. However, as recent research has noted, it is a variable that cannot only shape how different groups of individuals are affected by climate-related security risks. Gendered norms and power structures can also increase or mitigate the likelihood of climate-related security risks. This SIPRI Insights contributes to the growing body of research on gender, climate and security by analysing the gender dimensions of the four pathways of climate insecurity featured in past SIPRI studies: (a) livelihood deterioration, (b) migration and changing mobility, (c) tactical considerations of armed groups and (d) elite exploitation and resource mismanagement.
