Scoping review of early warning systems in improving disaster risk outcomes: perspective from evolution to usage in Southeast Asian countries
Abstract
BACKGROUND: Between 1970 and 2019, Asia-Pacific region experienced dramatic increase in climate and weather-related disasters, with a five-fold increase in frequency compared to previous decades. Early Warning Systems (EWS) play pivotal role in mitigating impacts of such disasters, with global estimates indicating potential savings of US $3–16 billion annually. According to the World Meteorological Organization (WMO), effective EWS issued within 24 h can reduce disaster-related damage by 30%. However, limited evidence exists on the effectiveness and evolution of EWS in Southeast Asia. This scoping review aims to examine the development, components, and implementation of EWS in the region and assess their role in disaster risk reduction. METHODS: A comprehensive literature search was conducted using databases such as PubMed, Web of Science, and IEEE Xplore, and reports from global agencies including Emergency Events Database, Centre for Research on the Epidemiology of Disasters, World Resources Institute, and WMO. The inclusion criteria focused on English-language studies detailing design, implementation, or evaluation of EWS within Southeast Asian countries. Out of 3,039 initially identified records, 81 studies were selected and analyzed using descriptive synthesis. RESULTS: Asia-Pacific region remains the most disaster-prone area globally, impacting 6.9 billion people and causing over 2 million deaths between 1970 and 2020. In Southeast Asia alone, the average annual…
