The habitats of lowland gorillas in the Kahuzi-Biega National Park, nestled in South Kivu, eastern Democratic Republic of Congo, have been under the watchful eye of scientists due to the looming threat of climate change. Recent research conducted by Heinicke, in collaboration with African climate researchers, scrutinized 333 sites across Africa where various ape species reside. Their findings painted a concerning picture: every single one of these habitats had experienced temperature increases.
In their study, Heinicke’s team projected the potential impacts of a world warmed to both 2°C and 3°C above pre-industrial levels. What they discovered was alarming – these habitats would not only witness more frequent heavy rainfall but also an escalation in the number of consecutive dry days. Such shifts in weather patterns could spell disaster for ape populations, disrupting their food sources and social structures.
Moreover, the research unveiled the heightened vulnerability of ape populations to extreme climate events such as wildfires, droughts, cyclones, and heatwaves. These events not only jeopardize food security but also have the potential to fragment ape groups, as witnessed during intense rainfall-induced flooding. The resulting isolation can erode the social networks crucial for their survival, leading to long-term repercussions across generations.
Ammie Kalan, a primatologist at the University of Victoria, highlighted the profound impact of such climate-induced disruptions, emphasizing the loss of knowledgeable individuals within ape populations. This, she argued, could significantly diminish the group’s resilience and exacerbate the challenges faced by younger individuals.
However, the immediate threat to ape populations in Africa remains habitat loss, compounded by the indirect pressures of climate change. The Intergovernmental Panel on Climate Change warns that rising temperatures will exacerbate heatwaves and droughts, already diminishing crop yields and productivity across the continent. In desperate circumstances, humans may resort to exploiting forest resources for sustenance, further encroaching upon ape habitats.
Rachel Ashegbofe Ikemeh, founder-director of the South-West/Niger Delta Forest Project, emphasized the cascading effects of climate change on human activities, citing instances of wildfires exacerbated by dry conditions. Such fires, often ignited during land-clearing activities, can rapidly escalate, posing a significant threat to ape habitats and exacerbating habitat loss.
Despite the prevailing focus on deforestation and hunting as primary threats to ape populations, experts stress the importance of integrating climate change considerations into conservation efforts. Understanding the potential impacts of both 2°C and 3°C temperature increases can bolster support for mitigation measures crucial for ape conservation.
Bella Lam, CEO of the Jane Goodall Institute of Canada, underscored the interconnectedness of conservation efforts with broader socio-economic factors. Any sustainable solutions, she argued, must address underlying drivers such as poverty, food insecurity, and gender inequality, which contribute to habitat encroachment and ultimately impact ape survival.
As climate change continues to exert pressure on ape habitats, concerted efforts are needed to mitigate its effects and safeguard these iconic species for generations to come.
