Damage and deaths caused by climate-related disasters across Africa will balloon if the continent’s so-called “hydromet” infrastructure for monitoring weather and water and is not urgently upgraded, scientists warn.
Hydrological and meteorological, or hydromet, hazards–including weather, water and climate extremes—are responsible for 90 per cent of total disaster losses worldwide, according to the World Bank.
The climate crisis is increasing the frequency and intensity of floods, droughts and heatwaves-with Africa expected to be among the regions hit hardest, according to a team of risk experts and climatologist, writing in the journal Nature.
Over the last two decades, the average number of deaths caused by flooding events in Africa was four times higher than the European and North American average per flood, observe the experts from United Kingdom (UK) and Africa working under the auspices of the University of Cambridge, UK. They say this is down to a lack of preparedness and warning systems.
Systems and technologies across the continent that monitor and forecast weather events and changes to water levels are “missing, outmoded or malfunctioning”, leaving African populations even more vulnerable to climate change, the researchers say.
Lead author Asaf Tzachor, a researcher at Cambridge University’s Centre for the Study of Existential Risk, said the implications for Africa’s population and economies were catastrophic.
“We expect damages and [the] death toll to swell,” Tzachor told SciDev.Net.
As climate change continues, extreme weather events will increase in frequency and intensity, putting communities across the continent at risk, according to Tzachor, who is also an educator at the interface of sustainability sciences, emerging technologies, and global risks.
“We further expect some areas in Sub-Sahara Africa to bear the brunt of extreme weather events to a greater extent, namely in the horn of African,” he said, citing protracted are a likely scenario.
The Niger Delta, in West would likely see delays in the onset of the wet season while countries south and west of Madagascar can expect increasingly intense cyclones Tzachor added.
To reach their conclusions, the researchers analysed 25 years’ worth of data relating to hydrological and meteorological disasters, including floods, flash- floods, droughts, and heatwaves, around the world.
They searched for patterns and anomalies in global data on thousands of disaster events, resulting in hundreds of thousands of deaths and billions of dollars’ worth of damages to infrastructure. Their analysis showed that Africa was four-times as vulnerable as other regions.
World Meteorological Organization data highlighted in the study also showed that the entire continent of Africa has just 37 radar stations while the USA and Europe’s combined total is 636, despite having a greater population size and a third more land.
