The more the world waits to cut carbon emissions, the greater the price on people and planet. This simple fact is borne out by the huge increase in the number of climate-related disasters over the past two decades.

 

Research from the UN Office for Disaster Risk Reduction (UNDRR) found that between 2000 and 2019, there were almost twice as many climate-related disasters as during the previous 20 years. The number of major floods, for example, doubled from 1,389 to 3,254. These disasters are being fuelled by the world's toxic love affair with carbon.

There was a time in which people discussed what the impacts of climate change might be on our children or grandchildren. It is clear that the pace of change is happening right here and now. As the planet continues to warm we have to accept that an increased number of climate-related disasters is inevitable, despite what progress is made between now and 2050.

Tried and tested 

But accepting their occurrence doesn't mean we can't do anything about it. There exists a tried and tested approach to tackling the growth in climate disasters. One of the main solutions is to set up an effective early warning system (EWS). This simple concept has proven so popular that the UN has set a target for every person on the planet to be covered by an EWS by 2027.  "The evidence is clear: early warning systems are one of the most effective risk reduction and climate adaptation measures to reduce disaster mortality and economic losses," the UN Secretary-General, António Guterres, recently commented.

The Adaptation Fund was created to support communities against the impacts of climate change. Disaster risk reduction coupled with early warning systems now account for around 18% of all the projects it funds. To date it has helped install 526 early warning systems across all continents, at the local, national and regional levels.

Mikko Ollikainen, who heads up the fund, recently commented that  "many of our projects are helping to reduce and avert further loss and damage," adding that "the fund is committed to supporting developing countries to build resilience to climate disasters. With the global urgency for adaptation expressed in recent international reports, such as the UNEP Adaptation Gap Report, we must accelerate and scale up our collective adaptation activities, including DRR/EWS. We have seen several instances where Adaptation Fund projects were successfully scaled up to create transformational DRR/EWS systems in countries."

On the ground 

Among the many projects which are now building out early warning systems, one in Colombia stands out. This small-scale, innovative example shows the benefits of a tailored approach working closely with local people. The La Mojana region in northern Colombia is an area of around 500,000 hectares, rich in wetlands and biodiversity. But it is also incredibly vulnerable to climate impacts and has frequently experienced bouts of severe flooding and drought.

Funded by the Adaptation Fund and carried out by the UN Development Programme together with the Colombian government, the project aimed to protect and strengthen local communities to future climate impacts. It managed to achieve this, in part, through creating stronger flood infrastructure, restoring damaged wetland areas, and the creation of an early warning system. A hydro-meteorological forecast and alert centre was created to monitor water levels, map flood threats, and provide safe evacuation routes. This provided 100% coverage for thousands of people in the affected regions, up from zero a few years earlier.

Heed the lessons 

Juana Madariaga, a restoration expert, told UNDP that: "We learned about everything. We received a lot of training and finally we were able to move this project forward...now we are supporting other communities in doing the same thing." The success has been taken forward by the Green Climate Fund which has greatly scaled up the funding and coverage of the EWS to the wider region.

A recent study by AF concluded that the most successful disaster risk reduction projects shared many of the same characteristics. These include leading with the community, empowering women and indigenous groups to design the campaign, and ensuring strong involvement from regional and national institutions. In addition, strong investment in data collection and improving data quality is essential to ensuring long-term sustainability and effectiveness.

These ideas may seem straightforward on paper but each region is unique. When it comes to disaster risk the value comes through forming lasting partnerships, a willingness to learn, and an understanding of local concerns. If the number of climate disasters only continues to grow as expected, we will need to heed these lessons and fast. Because if we cannot prevent disasters from happening, we have to learn to adapt, build resilience and reduce climate change risks.
