The Oil Spill scare in Uganda.
On the 4th April 2020, Daily Monitor reported an oil spill after an explosion of a geothermal hole in Kigorobya Sub County, Hoima district near Lake Albert https://www.monitor.co.ug/News/National/Oil-spill-scare-causing-panic-in-Hoima-District/688334-5513766-atcq9pz/index.html
What you should know about an oil spill
An oil spill is the release of a liquid petroleum hydrocarbon into the environment due to human activity, and is a form of pollution. Oil spills are caused by releases of crude oil from tankers, offshore platforms, drilling rigs, wells, and refined petroleum products or the spill of any oily refuse or waste oil.
The oil rich Albertine Graben is one of the most ecologically-diverse regions in the world boasting of having the world’s most spectacular animal and plant species including 52% of all African birds, and 39% of African animals. There are numerous water bodies including Lake Albert, Rivers Nile, Wambabya and Semuliki; Budongo forest and Murchison national park are rich in biodiversity will all be largely affected by the oil spill. This forms key habitats for endangered, vulnerable and endemic species like elephants, lions.
Due to the diverse flora and fauna in the region it had been feared that an oil spill could wipe out tourism, fishing industries and wildlife habitats in the Albertine Graben, this concern was raised during the public hearing on the Environment Social Impact Assessment report developed for CNOOC Uganda Limited for the King Fisher Project.
There have been disastrous oil spills globally with the Deepwater Horizon oil spill (2010) as one of the most recent and destructive.
These oil spills have had associated impacts to humans and the ecological environment which include;
- Contamination of drinking water supplies
- Air pollution from oil spill fires
- Loss of tourism and water resource extraction industries
- Local extinction of endemic species
- Disruption of breeding sites and habitats of aquatic organisms especially birds
- Respiratory poisoning
- Genetic and psychological disorders to organisms
- Loss of aquatic life from reduced insulation and inability to fly and escape from predators
Oil spill cleanups are difficult and usually expensive, but some of the following methods have been used;
- Bioremediation in which microorganisms to break down or remove oil; such as Alcanivorax bacteria or Methylocella silvestris,
- Controlled burning which can effectively reduce the amount of oil in water,
- Dispersants which can be used to dissipate oil slicks
- Dredging for oils dispersed with detergents and other oils denser than water
- Skimming in calm waters
- Solidifying using solidifiers to change the physical state of spilled oil through absorption and adsorption
- Vacuum and centrifuge where oil is sucked up along with the water,
- Acentrifuge can be used to separate the oil from the water allowing a tanker to be filled with near pure oil,.
Fortunately, the Uganda Environment (Oil spill prevention, control and management) regulations (2014) and the National Oil Spill Contingency Plan (2017) provide guidelines for oil spill and waste management outlining roles and responsibilities for each stakeholder right from the village level.
Key recommendations include; a multi-stakeholder approach should be followed involving teams from the Geological survey and mines, Petroleum Authority of Uganda (PAU), Ministry of Energy and Ministry of Water and Environment, NEMA, district leaders and local communities to manage the oil spill.
NEMA and PAU to closely monitor all other non-oil projects in the oil rich Albertine graben.
The spill response team should follow procedures that are environmentally sound to avoid damage to the ecosystem
Emphasis is also made on the Sensitization of the affected communities on management of this oil spill and alternative livelihood. Lastly, public engagement and risk communication around the oil area is needed to avoid additional risks.
