From 2000 to 2019, a total of 7,348 major climate disasters were recorded. They caused 1.23 million casualties and affected 4.2 billion people, resulting in global economic losses of approximately $2.970 trillion. This is a huge increase compared with disasters recorded in the 20 previous years. Some 91% of these disasters were due to floods, storms, droughts, heatwaves and other extreme climate events.
With this in mind, global organizations sounded the alarm and the telecom industry is stepping up to drive change. The United Nations committed to “substantially increase the availability of and access to multi-hazard early warning systems and disaster risk information and assessments to people by 2030”.
Authorities have the obligation to take steps to preserve life in case of an imminent risk. When disaster strikes, alerts and early warning systems can save lives by giving people just a little bit of extra time to act or evacuate. An early warning system is an adaptive strategy for climate change, utilizing integrated communication networks to aid communities in preparing for climate-related hazards. An effective Early Warning System (EWS) not only saves lives and jobs but also protects land and infrastructure, thereby supporting long-term sustainability.
Multi-hazard early warning systems are designed to manage various types of hazards and their impacts, whether they occur individually, simultaneously, in a chain reaction, or cumulatively over time, considering their potential interrelated effects.
To be effective, multi-hazard early warning systems must involve diverse stakeholders and actively engage at-risk communities. This comprehensive approach ensures the inclusion of appropriate technology, regulatory and legal frameworks, and adequate operational capacities:
In November 2022, the UN Secretary-General launched at COP27 an Executive Action Plan to implement the initiative and designated as the co-leads the World Meteorological Organization (WMO) and the United Nations Office for Disaster Risk Reduction (UNDRR).
By integrating climate change adaptation, the EW4All initiative supports the achievement of several SDG targets related to disaster resilience, including:
The initiative is built on four pillars to deliver effective and inclusive multi-hazard early warning systems (MHEWS):
This infographic highlights the critical need to view early warning and public alerting systems as a unified framework. It visually demonstrates how these systems, typically seen as separate entities, should be integrated to effectively anticipate and manage crises.
By uniting various public and private stakeholders dedicated to community safety, it creates a robust network capable of rapidly and efficiently responding to diverse threats.
The impact depends on location: the proximity of people and infrastructure, the vulnerability of that infrastructure, and the capability of the event to trigger further hazards, like a tsunami, landsliding, liquefaction, or widespread ash clouds. Real-time situational awareness is crucial for effective crisis management, as it provides decision-makers with a comprehensive 360° view of the unfolding emergency situation.
The ability to visualize live population heatmaps, integrate various data layers, and monitor threats around stakeholders and facilities enables more adaptive and dynamic decision-making throughout the management of critical events, ultimately helping to mitigate damage, protect lives, and restore normal operations as quickly as possible.
Earthquake Early Warning (EEW) systems have emerged as a critical tool for enhancing public safety in seismically active regions. These systems utilize advanced seismic monitoring technology to detect the initial waves of an earthquake, providing valuable seconds to minutes of warning before the more destructive shaking arrives. This early alert can trigger automated responses to protect critical infrastructure and allow individuals to take immediate protective actions, such as dropping, covering, and holding on. The effectiveness of EEW systems relies not only on the technology itself but also on robust public warning systems that can rapidly disseminate alerts to a wide population. By leveraging cutting-edge communication technologies, including mobile apps, wireless emergency alerts, and integrated smart city infrastructure, public safety organizations can ensure that potentially life-saving warnings reach citizens swiftly and reliably.
According to ITU's Facts and Figures 2023, 95%of the world's population has access to mobile broadband networks. Close to four in five people (78%) own a mobile phone. Even in the world’s Least Developed Countries, mobile phone ownership is at about 60%. This makes mobile networks an incredibly powerful communication channel to alert populations about imminent hazards. It also highlights the need to ensure that governments take advantage of mobile early warning systems to reach communities at risk.
ITU promotes a multi-channel approach, which combines all existing channels (cell broadcast, location-based SMS messages, mobile apps, satellites, social media, TV, radio, websites, sirens...), recognizes at-risk communities' diversity, and helps address inequalities and protect vulnerable populations.
In November 2023, Intersec joined ITU to foster emergency telecommunications (link to Press Release). Intersec is a strong proponent of combining Cell Broadcast and Location-Based SMS to stay ahead of the crisis management curve, with a series of successful public warning systems deployments in France, Croatia, Germany...

Spotlight: Common Alerting Protocol The Common Alerting Protocol (CAP) is a standardized format for emergency alerts and public warnings. It allows authorities to send consistent warning messages across multiple communication channels simultaneously, such as mobile phones, social media, radio, and television. CAP's simplicity and versatility make it a key tool in early warning systems, helping to quickly inform people about potential dangers. As of 2021, most of the world's population lives in countries implementing CAP, with a global initiative aiming for universal adoption by 2025. This widespread use of CAP is improving the effectiveness and reach of emergency alerts worldwide, potentially saving lives during disasters and emergencies. → More info in this article: CAP protocol: an essential framework for all emergency alert issuers |
Effective disaster preparedness and response is essential for minimizing the impacts of natural hazards.
Central to this effort is the strategic guidance for policymakers and development organizations, which lays the foundation for comprehensive early warning systems through policy frameworks.
The development and implementation of well-practiced and tested disaster management plans are also critical. These allow crisis managers to effectively inform operational assets, be aware of available evacuation routes, etc. Fostering collaboration and knowledge-sharing among diverse stakeholders promotes the exchange of ideas and best practices.
Embracing digital innovations is paramount not only to alert communities to impending dangers but also to provide them with the tools and knowledge to respond effectively. By integrating technological advancements, such as AI-powered predictive models, IoT sensors, and satellite imaging, we can enhance our ability to anticipate, prepare for, and mitigate the impacts of various hazards.
Community education and engagement are also crucial for ensuring widespread preparedness and resilience.
This collaborative, technology-driven approach paves the way for a safer, more resilient future in which communities worldwide are better equipped to face and overcome environmental challenges and natural disasters.
The WMO dashboard will be continuously enhanced with more data and new metrics.
Each of the four MHEWS elements contributes differently to the overall progress of MHEWS globally. "Overall, the data reveal improvement in the reporting and comprehensiveness of MHEWS in every country group and across each region. While a dramatic improvement is witnessed in the Asia and Pacific region and in Africa, significant gaps remain." Source: ESCAP report
Without early warning systems or services, the poorest and most vulnerable people are left especially exposed by the climate crisis.
CREWS works directly with countries to increase the availability of, and access to, early warning systems. Country and regional projects are implemented by the countries with the support of three Implementing Partners: the United Nations Office for Disaster Risk Reduction (UNDRR), the World Bank Global Facility for Disaster Reduction and Recovery (GFDRR) and the World Meteorological Organization (WMO).
The Asia-Pacific region's diverse geography includes fault lines, vast coastlines, and numerous volcanoes, making it one of the most disaster-prone areas in the world. For instance, the Pacific Ring of Fire is notorious for its high seismic activity, leading to frequent earthquakes and volcanic eruptions. Additionally, the region's extensive coastlines and tropical climate make it susceptible to powerful typhoons and tsunamis.
Nearly 45% of the world's natural disasters occur in the region, and more than 75% of those affected by natural disasters globally live in the region.
2 million people have lost their lives to disasters since 1970 in the region.
In 2022 alone, over 140 disasters struck the APAC region, leading to over 7,500 deaths, impacting 64 million people, and causing economic damage estimated at $57 billion.
The Asia-Pacific region has a narrow window to increase its resilience and protect its hard-won development gains from the socioeconomic impacts of climate change. In the absence of immediate action, temperature rises of 1.5°C and 2°C will cause disaster risk to outpace resilience beyond the limits of feasible adaptation and imperil sustainable development. Furthermore, climate disaster-related losses are already enormous, but the future cost of inaction today is greater still, with average annual losses increasing from $924 billion to almost $1 trillion, or from 2.9 to 3 percent of the regional GDP.

Despite the critical importance of Early Warning Systems, their coverage remains uneven across the Asia-Pacific region. According to the United Nations Office for Disaster Risk Reduction (UNDRR), only 67 percent of countries have reported implementing Multi-hazard Early Warning Systems (MHEWS) in the APAC region.
Significant disparities persist: despite the Asia-Pacific region showing higher levels of reporting in comparison to the global average, there are specific regions, such as southeast and southwest Asia, and vulnerable country classifications (LDCs, SIDS, LLDCs), where risk analysis at national and subnational levels needs substantial improvement (UN ESCAP, 2023a). Some countries, like Japan and Australia, have established robust early warning systems that serve as global benchmarks. However, a lack of resources and infrastructure hinders many nations from implementing effective EWS, leaving millions of people exposed to heightened disaster risks. On average, risk knowledge remains low, with many countries struggling to effectively develop and manage risk information and assessments. (Source: UNDRR Early Warning Systems Coverage).

Africa has been substantially impacted by natural disasters, which are set to increase in severity and frequency. And the true toll is likely to be much higher because of under-reporting.
More than 110 million people on the continent were directly affected by weather, climate and water-related hazards in 2022, causing more than US$ 8.5 billion in economic damages.
There were a reported 5 000 fatalities, of which 48% were associated with drought and 43% were associated with flooding.
African food systems are particularly vulnerable to climate extremes and shifts in weather patterns, as food production is largely dependent on rainfed agriculture and pastoralism. But its agricultural productivity growth has declined by 34% since 1961 due to climate change. This decline is the highest compared to what other regions of the world have experienced.
“Africa is responsible for less than 10 percent of global greenhouse gas emissions. But it is the continent which is the least able to cope with the negative impacts of climate change. Heatwaves, heavy rains, floods, tropical cyclones, and prolonged droughts are having devastating impacts on communities and economies, with increasing numbers of people at risk,” said WMO Secretary-General Prof. Petteri Taalas.
It takes more than a text to keep people safe. Integrated early warning systems are designed to predict and provide timely information about potential hazards to minimize the risk of disasters and comprise crisis management elements. Intersec’s approach to EWS begins with integrating diverse datasets, spanning open-source and closed-source information, and to maximize the reach and effectiveness of the early warning services, we offer a resolutely multi-channel and specialized software suite for early warning, emergency alerts, and crisis management requirements:
