Abstract for: Systemic Perspectives on Climate Change and Humanitarian Operations: Integrating Policy and Sustainability Agendas

Climate change is intensifying the frequency and severity of disasters, generating cascading impacts on vulnerable populations and infrastructure. However, existing analytical approaches often treat climate dynamics and disaster risk separately, limiting understanding of their co-evolution. This fragmentation constrains effective humanitarian planning and resource allocation under increasing climate uncertainty. This study adopts the system dynamics approach to integrate climate change dynamics with disaster risk processes. The model combines a simplified climate module based on the DICE framework with an endogenous disaster-risk structure representing exposure, vulnerability, and recovery. Through simulation, the framework explores long-term system behavior and evaluates alternative preparedness and response strategies. Simulation results show that rising temperatures increase the frequency of climate-related disasters, leading to higher affected populations and growing infrastructure damage. Without proactive investment in preparedness and recovery capacity, humanitarian systems become overwhelmed. Scenario analysis demonstrates that early preparedness investments significantly reduce long-term human impacts and infrastructure losses under climate uncertainty. The findings highlight the importance of shifting from reactive disaster response to proactive preparedness and adaptation strategies. Integrating climate and disaster dynamics provides a more systemic understanding of long-term risks. Such an approach supports better resource allocation and policy design, helping humanitarian systems avoid reinforcing vulnerability and improve resilience under escalating climate pressures.
