Giving priority to low- or no-regret interventions provides policymakers with the space required for responding to immediate needs without incurring the risk of maladaptation or of being faced with unintended consequences. The health sector provides a vast number of examples of low-regret actions, such as distributing mosquito nets, improving child nutrition, extending the coverage of health services, developing hygiene education campaigns, and improving water and sanitation facilities, among many others. Early warning systems constitute another example, as they grant authorities the flexibility to act pre-emptively and adjust civil security plans to the expected weather conditions, thereby reducing the number of lives at risk and/or the quantity of resources used.
