What We Do

Degraded Environment

Marine developments and operations

Marine developments and operations, such as industrial port developments and activities, ship-to-ship bunkering, finfish aquaculture and proposed offshore windfarms, are emerging as further threats to the breeding seabirds in the Namibian Islands' Marine Protected Area.

Pollution

Marine pollution is a major concern for the Namibian marine environment and its inhabitants, including seabirds. Plastic waste and oil spills are among the major sources of marine pollution in Namibian waters. These pollutants can have severe impacts on the health and reproductive success of seabird populations, including reduced fertility, decreased survival rates, and altered behavior in affected birds. In addition, oil spills can cause long-term impacts on the ecosystem, including reduced productivity and altered food webs.

Known marine oils spills in Namibia:

Year	Name/incident	Location	Wildlife affected
2021	Christmas Eve diesel spill	Skeleton Coast National Park	60 Cape Cormorants
2018	Fukuseki Maru No 7	Mile 108 south of Ugab River	Unknown
2018	Mystery spill - unknown origin	Walvis Bay Lagoon	Unknown number of oiled seabirds observed
2009	Mystery spill - unknown origin	Lüderitz	200 African Penguins
2005	Umfolozi	Port of Walvis Bay	Unknown
2005	Mystery spill - unknown origin	Ichaboe and Mercury Islands	60 African Penguins
2005	Vessel collision	Walvis Bay Harbour	1 Seal Pup / 5 Seabirds
1995	Irene: 700 t Heavy Fuel Oil	Walvis Bay	Unknown, but likely
1968	Andron	Between Walvis Bay and Lüderitz	Unknown

Ingestion of plastic can lead to physical harm, reduced nutrient uptake, and altered behavior in affected birds. Given the potentially severe impacts of marine pollution on Namibian seabird populations, it is crucial to implement effective management and mitigation measures. This could include increased monitoring and enforcement, as well as education and outreach efforts aimed at reducing the sources of marine pollution in the region.

Increased vessel traffic

Increasing vessel traffic in Namibian waters is a growing concern for the marine environment and its inhabitants, including seabirds. The increase in shipping traffic can lead to a range of negative impacts, including physical disturbance, increased noise levels, light pollution (and with it a collision risk for birds) and oil spills. These impacts can have significant consequences for seabird populations, particularly for those species that rely on the Namibian coast for breeding and foraging.

Shipping traffic can lead to a reduction in the foraging success of seabirds, as the disturbance from passing ships can cause birds to abandon their feeding sites. This can result in reduced energy intake and decreased reproductive success, which can affect the overall health of seabird populations in the region.

In addition to physical disturbance, shipping traffic can also increase the risk of oil spills. A study by Cordero et al. (2017) found that shipping accidents are the largest source of oil spills in the region, and that these spills can have severe impacts on seabird populations. For example, oil spills can cause direct mortality, reduced reproductive success, and altered behaviour in affected birds.

Given the potential impacts of increasing vessel traffic on Namibian seabird populations, it is important to implement effective management strategies to minimise these impacts. This could include measures such as shipping lanes that avoid critical habitats for seabirds, increased monitoring of shipping traffic, and improved spill response planning.
