Climate Change & Invasive Species Threaten Uganda's National Parks - Scientists Are Fighting Back

Retreating glaciers on the Rwenzori Mountains. Wetlands choked by invasive weeds. Grasslands disappearing at an alarming rate. Uganda's national parks are under siege from multiple environmental crises, but the country's top wildlife scientists say research is their most powerful weapon.

At Uganda's inaugural National Biodiversity Research Symposium, experts sounded the alarm over the cascading effects of climate change and biological invasion, warning that without urgent, science-led intervention, the country risks losing the very ecosystems that power its booming tourism economy.

Principal Robert Baluku of the Uganda Wildlife Research and Training College painted a stark picture of what is unfolding inside Uganda's protected areas. Invasive plant species, he said, have fragmented habitats to such an extent that wildlife is being pushed out of parks and into surrounding communities, directly fuelling the human-wildlife conflicts that have made headlines across the country.

"When the park is covered by invasives, what happens is that the animals lack food and seek options outside the national park," Baluku explained. "That is the reason we have the wildlife conflicts we've been seeing. Research on invasives is how we stop that."

The Rwenzori glaciers, one of Uganda's most iconic natural features and a major tourist draw, are among the casualties of a warming climate. Baluku acknowledged the glaciers are visibly shrinking but insisted restoration is not only possible but already underway through coordinated action involving UWA, NGOs, and international organisations.

"Climate change issues are real, but they can be reversed if we put our energies together. It is not a one-day business, it is a long-term thing," he said with characteristic resolve.

Dr. Basil Ajer, Director at the Ministry of Tourism, Wildlife and Antiquities, linked the environmental crisis directly to Uganda's economic future, noting that approximately 70% of tourism revenue is generated through nature-based products. Any degradation of natural habitats, he warned, translates to a loss of Uganda's competitive edge on the global tourism market.

"We have been losing out on tourism because of the challenges our national parks are facing," Dr. Ajer acknowledged. "But through research, I am sure that all this will come to an end."

Both officials called for an urgent prioritisation of genetic diversity in conservation strategy, an area Baluku said has been dangerously neglected. The symposium's findings are set to be published in a new wildlife research journal, establishing a scientific roadmap to guide Uganda's next generation of conservation policy.
