Leading researchers have launched a major scientific initiative to investigate - and help protect - the fragile Congo Basin Forest region in central Africa, one of the world’s most important but little understood ecosystems.
They say the Congo Basin Science Initiative will transform the understanding of the Congo Basin, an area of 240 million hectares of contiguous tropical forests that absorb a vast quantity of carbon, which helps to moderate the impact of global climate change.
The Initiative has been launched at the Three Basins Summit, a major gathering to discuss the world’s three large tropical forest regions being held in Brazzaville, Republic of the Congo.
At the summit, leading researchers - including Professor Stephen Lewis, a prominent expert on the Congo forests from the University of Leeds and University College London – highlighted the stark difference between what scientists know about the Congo Basin and what they know about the Amazon Forest in South America, which has been the subject of intense scientific enquiry through what is known as the Large-Scale Biosphere-Atmosphere Experiment or LBA.
Involving 120 projects and 1700 researchers, the decade-long scheme in the Amazon has revealed the critical role that the Amazon Rainforest plays in regulating the Earth’s climate. It has also helped train local scientists and has put Brazil at the forefront of rainforest science.
The researchers meeting in Brazzaville aim to replicate that approach with the creation of the Congo basin Science Initiative.
Professor Raphael Tshimanga, a leading expert on the Congo Basin based at the University of Kinshasa in the Democratic Republic of the Congo and one of the leaders of the project, said: "The Congo basin is a vast and important area that straddles central Africa, the world’s second green lung after the Amazon.
“If we can replicate what has been achieved through investing in research in the Amazon, we will be in a much stronger position to understand the threats to this unique African ecosystem not only from climate change but also from deforestation and pollution from mining and oil exploration.”
Key scientific questions
Scientists have drawn up key scientific questions that need to be answered to assess the health of the Congo Basin forests.
Professor Lewis, who helped to develop the science plan for the Initiative with scientific colleagues in the Congo region, said: “In the Amazon, scientists have uncovered a tipping point where beyond a certain level of deforestation and climate change will lead to a mass die-back of the southern and eastern part of the Amazon.
“In the Congo Basin, scientists do not know if there is a tipping point, because we do not yet have the data to investigate this.”
Underinvestment in Congo Basin science
The scientists argue that there has been “severe underinvestment” in the science to understand the Congo Basin and many barriers to researchers to lead high-level studies.
In recent years, only 11% of international funding for forest protection and sustainable management in tropical areas has been channelled to projects in the Congo Basin, whereas 34% went to the Amazon and 55% to southeast Asia.
The lack of investment meant that in the latest IPCC global climate assessment, the Congo Basin was one of only two location in the world without sufficient data needed to assess past trends in extreme heatwaves.
The meeting in Brazzaville is calling for $100 million to be invested in a ten-year science programme focussed on the Basin region, with a further $100 million to give PhD training to scientists from the Congo region. Once qualified, those scientists will be able to lead and co-ordinate complex studies.
Funding would have to come from international donors, UN agencies and philanthropists. The researchers say with international spending on research and development hitting $2.4 trillion in 2020, the funding needed to understand and protect the world’s second tropical forest is relatively modest.
Professor Lewis added: “Central Africa needs more scientists who can monitor the forests, rivers and climate of the region. Central Africa needs more scientists who can advocate for evidence-based policy, so that these countries can develop and become prosperous, but without the mass-scale destruction of nature that has occurred in places like the UK.”
Congo Basin
The Congo Basin forests are a global biodiversity hotspot and home to elephants, gorillas, chimpanzees and bonobos. Rainfall from the region is recycled by the forests and transported beyond central Africa, feeding rivers that are used by 300 million people as far afield as Ethiopia and Egypt.
There are major discoveries being made in the Congo Basin, with scientist recently mapping the world’s largest tropical peatland, and many species that are new to science, with recent finds including a new species of gecko, an air-breathing catfish, and a new species of coffee.
But experts fear as the climate gets warmer, that process could see the undisturbed Congo basin’s forests switch from being one of the world’s biggest absorbers of carbon to an emitter of carbon.

Analysis finds diversity on the smallest scales in sulfur-cycling salt marsh microbes
2023-10-26
WOODS HOLE, Mass.— At the surface, salt marshes and their windswept grasses can look deceptively simple. But those marshes are teeming with biodiversity, from the insects and migrating birds in the air all the way down to the microbes that live in the soil. Scientists from the Marine Biological Laboratory (MBL) have discovered that even among the sulfur-cycling microbes that are responsible for the “rotten egg gas” smell in salt marsh air, diversity extends all the way to genomes and even to individual nucleotides.

Admissions for bronchiolitis at children’s hospitals before and during the pandemic
2023-10-26
About The Study: The results of this study of 41 large U.S. children’s hospitals suggest that bronchiolitis hospitalizations decreased transiently and then increased markedly during the COVID-19 pandemic era. Patients admitted during the pandemic era were older and were more likely to be admitted to an intensive care unit. These findings suggest that bronchiolitis seasonality has not yet returned to pre-pandemic patterns, and hospitals should prepare for the possibility of atypical timing again in 2023.

How adults understand what kids are saying
2023-10-26
CAMBRIDGE, MA -- When babies first begin to talk, their vocabulary is very limited. Often one of the first sounds they generate is “da,” which may refer to dad, a dog, a dot, or nothing at all.
How does an adult listener make sense of this limited verbal repertoire? A new study from MIT and Harvard University researchers has found that adults’ understanding of conversational context and knowledge of mispronunciations that children commonly make are critical to the ability to understand children’s early linguistic efforts.

Malaria protein discovery offers path for novel antimalarial intervention strategies
2023-10-26
The discovery of a malaria protein that helps the parasite grow inside red blood cells and plays a key regulatory role in the parasite’s immune evasion tactics could pave the way for new vaccines or therapeutics to combat the deadly infection.
The protein, known as PfAP2-P, was previously identified in a KAUST-led study that explored malarial genes and proteins displaying rhythmic 24-hour expression patterns — an adaptation that allows the parasite to synchronize its activities with those of the host during the human blood stage of its developmental cycle[1].
The expression levels of PfAP2-P seem to peak first around ...
