Connectivity drives economic development and underpins critical services in the aftermath of disastrous weather events or earthquakes. However, nearly all types of climate and natural hazards can cause damage to telecommunications (telecom) networks and threaten service delivery. For countries that experience multiple types of climate hazards, building telecom infrastructure is a challenge for public practitioners and telecom operators. This guide provides recommendations for practitioners in designing, preparing, and implementing resilient telecom infrastructure projects. For instance, resilience-building measures, such as risk analysis, redundancy, backup power, customization, and disaster planning, are important for strengthening the resilience of telecom infrastructure deployments. While no single intervention will make telecom infrastructure fully resilient, investment in a range of coordinated actions can reduce the probability of failure and enable operators to maintain acceptable service in the face of increasing climate hazards.
