This paper calls for policy-makers, governments and donors to increase financial support forclimate action in Fragile and Conflict Affected Settings (FCAS). The link between climate changeand conflict is highlighted, emphasising that climate hazards can undermine peace and stability,exacerbate existing conflicts and create new ones. It shows that conflict and fragility increasevulnerability to climate change and limit adaptive capacity, while the nature of conflict can drivevulnerability more than climate change itself. Financial providers of climate-related activities in FCAS are urged to recognise the complexities of the link between conflict and climate change and adopt risk-informed approaches. It is crucialto recognise that insufficient climate finance can exacerbate vulnerability to climate-relatedsecurity risks and that ambitious mitigation efforts are necessary to address the increasing costs of adaptation over time.
