Lake Victoria - Africa's Largest - "On Its Knees" Thanks To Invasives, Sewage, Overfishing
Lake Victoria, Africa's largest fresh water body and the world's second largest lake, is no longer fresh. The lake is choking with pollution from industrial and agricultural wastes, as well as raw sewage from Kisumu, Kenya's third largest city of just under 400,000 residents. Its problems are compounded by illegal fishing, catching of juvenile fish, and infestation by the invasive water hyacinth (Eichhornia crassipes). And there's also the carnivorous Nile perch (Lates niloticus), an introduced behemoth of a fish that can grow to 200 kilograms (440 pounds) and has already wiped out nearly half of the 500-plus endemic species of Victoria cichlids — colorful fishes that once thrived within the lake basin.
"This lake is in a very sorry state," Moris Okulo, a trained ecologist who has worked as a guide at the lake's Dunga beach in Kisumu for the past 20 years, told mongabay.com. "Everything about the lake is wrong. Fishermen are using wrong fishing gears, but nobody arrests them. Industries are discharging waste into the lake, but no action is being taken. Some people have built structures including latrines inside the lake with the knowledge of law enforcing personnel, but nobody is even talking about it," he lamented.
EDIT
All that, as well as the lake's ecological integrity is at stake. Authorities in the three countries are fully aware of the lake situation, with the Kenya National Cleaner Production Centre (KNCPC) pointing out that 88 industries operating around the lake collectively dump seven tons of industrial waste into the lake every year. Yet none of the three countries prosecute offenders. Instead, KNCPC encourages businesses in the three countries to voluntarily adopt waste-prevention technologies, promising eventually to set mandatory requirements. The KNCPC and its regional partners also reward manufacturing companies they deem to have cut environmental pollution through a $3.5 million World-Bank-funded program to reduce pollution to the lake basin. Within the reward scheme, Kenya's Nzoia Sugar Company Ltd won the 2014 solid waste management award, despite the fact that its farmers use chemical fertilizers that end up in the Nzoia River, which feeds into the lake.
"The truth is that all these industries located near the lake have a hidden agenda to release effluents into the lake. If hard pressed, they will talk about measures put in place or being put in place to purify the water before it is released into the lake," Gaster Kiyingi, a Ugandan communications consultant and activist who has worked for environmental groups in the region for the past decade, told mongabay.com.
