African Vulnerability to Climate Change Amplified by Inadequate Weather Monitoring – Experts

As the world grapples with escalating climate crises, including intensified flooding, droughts, and heatwaves, a consortium of experts has sounded a resounding alarm about the heightened risk faced by African nations.

Climate-driven events are becoming increasingly frequent and severe, and African countries are particularly susceptible due to the inadequacy of their weather monitoring and forecasting systems.

This deficiency in monitoring infrastructure puts the continent’s populace in a precarious position, leaving them exposed to the harsh realities of climate change.

Led by the University of Cambridge, Risk Experts and Climatologists from the UK and Africa have underscored that many of the systems and technologies employed across Africa to monitor and predict weather events and water level fluctuations are either “missing, outmoded, or malfunctioning.”

Consequently, the African continent is grappling with higher vulnerability to the impacts of climate change.

The warning, published on Monday on the University of Cambridge’s website, elucidates that without swift and substantial enhancements to their “hydromet infrastructure,” the toll of destruction and loss of life caused by climate-related disasters across Africa will dramatically escalate.

Comparative research highlighted by the journal Nature underscores the severity of the situation. Over the past two decades, the average death toll resulting from flooding events in Africa has been four times higher than the European and North American average per flood.

This discrepancy led the experts to investigate data from the World Meteorological Organization (WMO) and they discovered that the entire African continent has a mere 6% of the number of radar stations present in the US and Europe combined.

This is astonishing considering that Africa boasts a comparable population size and a landmass that is a third larger.

Radar stations play a crucial role in detecting weather fluctuations, rainfall patterns, and long-term climate trends, serving as essential tools for forecasting floods and other meteorological events. Astonishingly, Africa is equipped with just 37 such stations.

Further analysis of WMO data unveiled that more than half of the operational radar stations in Africa cannot produce accurate data to predict weather patterns even for the next few hours. This glaring inadequacy necessitates urgent intervention.

The experts have called upon the international community to significantly increase funding for systems that mitigate the risks posed by climate-induced disasters.

Currently, a meager $0.47 out of every $100 spent on global development aid is allocated towards any form of disaster risk reduction.

Dr. Asaf Tzachor, co-lead author and research affiliate at Cambridge’s Center for the Study of Existential Risk (CSER), stressed the critical nature of the situation, stating, “The vast gaps in Africa’s disaster reduction systems are in danger of rendering other aid investments redundant.”

He emphasized that addressing the hydro-meteorological deficiencies is paramount to safeguarding other developmental endeavors.

To underscore their point, the experts draw a poignant comparison between two Category 4 storms: Tropical Cyclone Idai that struck southeastern Africa in 2019 and Hurricane Ida that hit the eastern US in 2021.

Despite similar wind speeds exceeding 200 km/hour, the US population received timely evacuation alerts, leading to a death toll under 100. In contrast, the limited ‘hydromet’ capabilities in Africa resulted in over 1,000 lives lost during Cyclone Idai.

The disparity between well-equipped hydromet systems in the Global North and the scarcity, obsolescence, or malfunctioning of these systems in Africa is glaring.

The experts emphasize that well-funded hydromet systems should become a priority to empower at-risk populations to mitigate and adapt to weather-related hazards.

To bridge the weather-warning gap, the team has outlined a series of recommendations.

Firstly, identifying the most vulnerable areas is essential due to the wide-ranging climate hazards across the continent.

Secondly, enhancing the number of weather stations across Africa must be coupled with improved satellite monitoring and substantial training initiatives for African meteorologists.

Furthermore, adopting the latest computational techniques, including AI-powered approaches that integrate weather data with social media activity for disaster prediction, is paramount. The expansion of early warning systems, providing clear instructions for evacuation in local languages, is also necessary.

Ultimately, the experts underscore the immense significance of substantial investment in hydromet systems, highlighting the considerable potential returns.

While the World Bank estimates a price tag of $1.5 billion for continent-wide hydromet systems, the investment could save African countries from $13 billion in asset losses and $22 billion in livelihood losses annually.

The urgency of these enhancements is palpable, as Africa’s vulnerability to climate change is exacerbated by its deficient weather monitoring infrastructure. With fewer radar stations serving a larger population and landmass, the continent is in dire need of action to ensure resilience against the ravages of a changing climate.
