A recent study conducted by the Vrije Universiteit Brussel (VUB) has found a clear warming trend in the Congo Basin since the 1960s. The study, which utilized handwritten archives from Congo and Belgium, discovered that temperatures in the region have been rising steadily over the past several decades. According to the study, between 1961 and 1990, maximum temperatures increased by approximately 0.7°C, while minimum temperatures rose by 0.3°C and average temperatures by 0.5°C.
The study's findings are based on data from the archives of the Institut national pour l'étude et la recherche agronomiques (INERA) in Yangambi, Democratic Republic of Congo, as well as Belgian state archives. The research team, led by Derrick Muheki, a researcher and PhD student at VUB, collected over 9,000 handwritten monthly weather observation records from 37 stations across the DRC during two field campaigns in 2023. These records were used to create a database containing over one million daily weather observations.
The study's results show that the warming trend in the Congo Basin has continued into the 2000s. Additionally, the number of hot days per year nearly doubled between the 1960s and 1980s. The researchers note that this warming trend is significant, as the Congo Basin has been largely neglected by the scientific community in terms of climate research. The study's findings have important implications for understanding climate change in the region.
The research team at VUB emphasizes that their study provides one of the most comprehensive sets of climate data for the Congo Basin region to date. By combining the handwritten archives with previously collected data, the team was able to create a robust dataset that sheds light on the region's climate trends. The study's lead author, Derrick Muheki, played a key role in collecting and analyzing the data.
The warming trend in the Congo Basin has significant implications for the region's ecosystems and populations. Rising temperatures can lead to changes in precipitation patterns, increased risk of droughts and heatwaves, and impacts on agriculture and human health. The study's findings highlight the need for continued climate research in the region to better understand these changes and develop effective adaptation strategies.
The study's results were made available to the Congolese press agency through a communiqué received on Monday. The agency, ACP, reported on the study's findings, highlighting the importance of the research for understanding climate change in the region. The study's authors hope that their work will contribute to a greater understanding of climate trends in the Congo Basin and inform decision-making on climate change mitigation and adaptation.
The VUB study is a significant contribution to the field of climate research in Africa. By using innovative methods to collect and analyze historical climate data, the research team was able to shed new light on the warming trend in the Congo Basin. As climate change continues to be a pressing global issue, studies like this one are essential for informing our understanding of regional climate trends and developing effective strategies for mitigating and adapting to climate change.
