Environmentalists say this move contradicts earlier safeguards aimed at preserving the ecological integrity of other islands in Kalangala.
The district comprises 84 islands but only 64 are inhabited.
Mr Joseph Byaruhanga, the Kalangala District environmental officer, said the original Environmental and Social Impact Assessment (ESIA) recommended limiting oil palm to Buggala to protect the natural forests and promote food crop diversity elsewhere.
“The intent was to preserve the natural forests on other islands and maintain food crop cultivation,” Byaruhanga explained in an interview on June 3.
Oil palm cultivation in Kalangala began in 2006, primarily on mailo land. Currently, over 12,000 hectares are under cultivation, including land managed by smallholder farmers and Oil Palm Uganda Limited (OPUL).
Records at the Kalangala District Environment Office indicate that forest cover has plummeted from 57 per cent in 1954 to just 22 per cent currently. The primary drivers of deforestation include rice farming (20 per cent), oil palm growing (18 per cent), and a combination of timber harvesting, settlement, and charcoal burning (16 per cent).
“The economic benefits are pushing residents to clear more land for oil palm, but this has long-term consequences—sedimentation, pollution, and even increased lake accidents and windstorms due to changing weather patterns,” Byaruhanga warned.
“Kalangala is surrounded by shallow waters. Without vegetation to anchor the soil, siltation could gradually fill the lake. If oil palm must expand, then we need a parallel forest restoration programme.” he added.
Mr David Kureeba, a senior programme officer Forests , Biodiversity and Climate Change at National Association of Professional Environmentalists (Nape) cautioned that unregulated oil palm expansion is a looming environmental disaster in the island district . “Although oil palm is a tree-like crop, it does not replicate the ecological functions of natural forests,” he explained.
“Oil palm trees may live for 25 years, but they are no match for indigenous forests. Natural forests are biodiversity hubs with wide canopies, climbing plants, and complex ecosystems,” he added.
Mr Kureeba also noted that forest cover clearance releases greenhouse gases like methane and carbon dioxide, exacerbating global warming. “Methane alone contributes to nearly a quarter of global climate change impacts. Destroying forests releases these gases into the atmosphere,” he said.
“Forests also regulate climate through evapotranspiration, contributing to cloud formation and rainfall. The morning dew and fresh air we enjoy come from forests. Without them, even moisture exchange through leaf stomata disappears,” he further explained.
Mr Frank Muramuzi, NAPE Executive Director, emphasised Kalangala’s vulnerability due to its island geography.
“Clearing forests removes natural windbreaks, exposing the area to strong winds and dangerous weather patterns like tornadoes,” he said.
“Oil palm doesn’t absorb as much carbon dioxide or release as much oxygen as broadleaf trees. Replacing forests with oil palm only worsens the problem,” he added.
Mr Muramuzi also criticised Uganda’s EIA process. “Developers often conduct their own assessments, which tend to downplay environmental risks in favour of economic benefits,” he said.
Despite these concerns, project proponents insist the expansion is being handled responsibly.
Mr Boaz Zaake, an agronomist with Ssese Oil Palm Growers Cooperative Society Limited ( SOPAGCO), said farmers are using cover crops and maintaining buffer zones to prevent erosion and water pollution.
He also argued that most of the targeted land for new oil palm fields was previously abandoned due to tsetse fly infestations and not part of any protected forests.
“All national forests have been preserved. Oil palm trees do produce oxygen just like other trees,” he said.
Mr Muramuzi, however, dismissed this claim, arguing that oil palm trees contribute little to climate regulation.
“Oil palm isn’t a real tree in ecological terms. It has a small leaf surface and limited capacity for carbon capture. Unlike broadleaf indigenous trees, it offers minimal environmental benefits,” he said.
Kalangala Resident District Commissioner, Fred Badda, said an Environmental Impact Assessment will be conducted before any new expansion of oil palm fields is done.
“We are currently assessing the land’s availability and historical use—whether it was forested or not—before proceeding with the EIA,” he said.
At least 11,800 hectares of oil palm trees have so far been planted on Kalangala’s main Island of Buggala in the past two decades, and recently, the project started expanding to other islands of Bunyama, Bukasa and Bubembe.
