The Lake Victoria Basin Commission (LVBC) has launched a comprehensive study on the water quality of Lake Victoria, a critical resource relied upon by more than 45 million people across East African countries.
Funded by the German Development Agency (GIZ) as part of the EAC for Nature Project, the study is scheduled to begin next week, following a three-day training workshop for experts on water sampling techniques and research methodology.
The training is taking place in Mwanza, United Republic of Tanzania and is expected to end on June 6th 2025.
Sample collection will begin in Tanzania before proceeding to Uganda and Kenya, the other two East African Community (EAC) partner states that share the Lake Victoria Basin.
Lake Victoria Basin Commission’s Deputy Executive Secretary Eng Coletha Ruhamya noted growing concerns about unusual changes in the lake’s ecosystem, including the widespread presence of water hyacinths.
“It’s not that we’ve identified a specific issue, but there are signs of irregularities. When you look at the lake with the naked eye, listen to how communities speak about the growing spread of water hyacinths, and observe ongoing human activities along the shoreline — you realize something may be wrong. Clear or colorless water doesn’t always mean clean water, which is why we’re undertaking this study,” Ruhamya explained.
She emphasized that the study’s findings will be crucial in guiding the conservation of the lake’s biodiversity and ecological balance. In addition to evaluating water quality, the research aims to assess the extent of pollution and cleanliness across different parts of the lake, with a view to developing actionable projects and interventions.
Dr. Renatus Shinhu, Director of the Lake Victoria Basin Water Board (LVBWB), confirmed that all three participating countries — Tanzania, Kenya, and Uganda — will collect and submit water samples for laboratory analysis.
“We’re beginning with training to ensure the team understands how to properly collect samples and use the necessary equipment. Once training concludes, the actual research will commence,” said Dr. Shinhu.
He noted that the data collected will support EAC member states in designing and implementing projects to improve and safeguard water sources, particularly Lake Victoria.
“As the East African Community, this initiative provides an opportunity to develop cross-border environmental protection projects and improve shared policies,” added Ruhamya.
Commenting on the lake’s current condition, particularly on the Tanzanian side, Ruhamya stated that daily assessments show the lake remains in relatively good shape. However, pollution is increasingly evident near the shoreline.
She added that water quality improves significantly between 50 to 100 meters from the shore, but the cumulative impact of human activities poses a serious threat to the lake’s long-term health.
GIZ Technical Advisor Omary Myanza said the agency decided to support the initiative to generate credible data and insights that can inform decision-making across the region.
“We’re funding this project because the data it generates will enable the East African Community and the Lake Victoria Basin to develop robust strategies to manage and protect the lake’s environment. We’ve already observed several emerging concerns, including the proliferation of water hyacinths,” Myanza said.
The study is expected to play a pivotal role in shaping environmental policy, supporting cross-border collaboration, and ensuring the sustainable management of one of Africa’s most vital freshwater ecosystems.
