Report: Global status of multi-hazard early warning systems

This UNDRR-WMO joint report assesses the current global status of multi-hazard early warning systems (MHEWS) against Target G of the Sendai Framework, collating data officially reported by the Member States with data collected through a WMO survey.

The findings identify countries’ challenges and note good practices in forecasting capabilities, early warning coverage, and systems to act on them.

The primary goal of disaster risk reduction is prevention. But when that is not possible, then it is important to minimize the harm to people, assets and livelihoods through early warning systems.

This is especially important in the case of sudden-onset or fast-moving hazards such as tsunamis, cyclones and volcanic eruptions, but is also relevant to slower hazards such as drought and disease outbreaks. 

It is not enough for an early warning system to correctly identify an incoming hazard, but it must also ensure that the populations and sectors that are at risk can receive the alert, understand it, and most importantly, act on it. Hence, an early warning must trigger early action.  In the case of fast-moving hazards, this sometimes means evacuating and seeking appropriate shelter.

The United Nations General Assembly has designated 13 October as International Day for Disaster Risk Reduction to promote a global culture of disaster risk reduction.

It is an opportunity to acknowledge the progress being made toward reducing disaster risk and losses in lives, livelihoods and health in line with the international agreement, the Sendai Framework for Disaster Risk Reduction 2015-2030 adopted in March 2015.

The Sendai Framework has seven strategic targets and 38 indicators for measuring progress on reducing disaster risk and losses. These indicators align implementation of the Sendai Framework with implementation of the Sustainable Development Goals and the Paris Agreement on climate change.

In 2022, the International Day will focus on Target G: “Substantially increase the availability of and access to multi-hazard early warning systems and disaster risk information and assessments to people by 2030.”

We need end-to-end and people-centred systems which will stop the spiral of disaster destruction and contribute to a more sustainable, more resilient and more equitable future.
