Africa urgently requires enhanced support to combat climate change, according to Kachinga Silwimba, a climate researcher. Speaking from his base in Boise, Idaho, United States, Mr. Silwimba emphasized the need for African governments to reallocate funding and prioritize research to address climate-related challenges.
A World Economic Forum report from February 2024 estimated that Africa needs approximately US$52.7 billion annually for effective climate action. However, this funding—largely expected to come through international climate adaptation initiatives—has consistently fallen short.
Silwimba highlighted the devastating drought in southern Africa as a case study of how inadequate investment in climate research and adaptation measures can have severe consequences. This drought led to a significant power crisis in Zambia and Zimbabwe, countries heavily reliant on hydropower.
“We need to prepare for the future, not only in terms of rainfall but also for hydroelectric power, because everything is interconnected,” Silwimba stated. “If we don’t have rainfall, we lose power, crop production drops, and livelihoods are disrupted.”
Urgent Need for Investment in Science and Research
Silwimba, who is pursuing a doctorate in data science, has been vocal about the importance of research in mitigating climate risks. He previously argued, during his master’s studies in mathematical sciences in 2021, that southern Africa’s changing climate could lead to catastrophic outcomes without proactive measures.
“Changes in the mean climate, coupled with extreme weather events, will intensify as greenhouse gas concentrations rise,” he wrote, citing research by Seneviratne et al. (2012). He warned that failing to forecast and address these trends could result in “massive loss of human life and property.”
Southern Africa’s vulnerability is further exacerbated by insufficient information, limited financial resources, and inadequate technological capacity. Between 1970 and 2012 alone, the region faced climate-induced losses of at least US$10 billion, according to Silwimba’s findings.
Collaborative Solutions Needed
Silwimba called for collective efforts involving scientists, policymakers, and international stakeholders to develop and implement sustainable solutions. “The involvement of all key players is crucial to create appropriate measures to prevent the potential negative impacts of climate change,” he said.
His remarks underscore the pressing need for African nations to prioritize investments in climate adaptation and mitigation. By doing so, the continent can better prepare for the inevitable challenges posed by a warming planet, safeguard livelihoods, and ensure sustainable development.
