Lake Sevan clean-up pledge draws attention to a wider water crisis

A new pledge to remove waste from the shoreline of Lake Sevan has put renewed attention on the long-running environmental pressures facing Armenia’s most important freshwater body.

The Saad Kassis-Mohamed Center, an initiative of the WeCare Foundation in Cape Town, says it will fund the removal of 100,000 litres of waste and debris from the shoreline and coastal zone of Lake Sevan. The commitment forms part of what the Center describes as a broader one-million-litre conservation campaign.

The announcement is modest in scale when measured against the lake’s wider ecological problems, but it points to a larger issue: Lake Sevan’s future will depend not only on clean-up operations, but on whether Armenia and its international partners can reduce the pressures that continue to affect the lake’s water quality and long-term water balance.

Lake Sevan is the largest freshwater lake in Armenia and the wider Caucasus region. Located at about 1,900 metres above sea level, it is widely recognised as one of the major high-altitude freshwater lakes in the world. It is fed by 28 rivers and drains through the Hrazdan River. Its basin supports drinking water supplies, irrigation, aquaculture, hydropower, tourism and local livelihoods.

The lake has also been under pressure for decades. During the Soviet period, water was heavily used for irrigation and hydropower, leading to a major fall in lake levels and long-term changes in the surrounding ecosystem. Armenia later introduced legal limits on annual water withdrawals, commonly cited at 170 million cubic metres. In 2023, that limit was reported to have been exceeded, with withdrawals reaching around 228 million cubic metres.

More recent official reporting has pointed to a significant rise in Lake Sevan’s water level during the first half of 2026. Environmental experts, however, have continued to warn that water level alone does not resolve the lake’s deeper problems. Pollution, untreated wastewater, agricultural runoff and pressure on the lake’s watershed remain central concerns.

One of the most serious ecological risks is eutrophication. Scientific research has linked the growth of cyanobacterial blooms in Lake Sevan to rising nutrient levels, including phosphorus and nitrogen entering the lake system. A major bloom was recorded in 2018, with research published in the International Review of Hydrobiology identifying toxic cyanobacteria and warning that the lake had moved away from its former oligotrophic condition towards a more eutrophic system.

Such blooms can affect water quality, fisheries, livestock and public health. They also underline the importance of wastewater treatment and better management of agricultural runoff across the watershed, rather than relying only on shoreline clean-ups after pollution has already reached the lake.

Lake Sevan has already been the focus of international support. The EU4Sevan project, co-financed by the European Union and Germany’s Federal Ministry for Economic Cooperation and Development, supported environmental protection, water monitoring, wastewater treatment capacity, land-use practices and governance around the lake. The project was implemented with the involvement of GIZ and the United Nations Development Programme.

That work helped strengthen the institutional framework around Lake Sevan, including management planning and long-term conservation thinking. But the central challenge remains implementation. Plans and strategies can guide restoration, but sewage infrastructure, runoff controls, transparent monitoring and enforcement of withdrawal limits are the measures that determine whether the lake’s condition improves.

In its announcement, the Saad Kassis-Mohamed Center called on the Government of Armenia to enforce the annual water withdrawal limit, expand adequate sewage treatment infrastructure for communities within the watershed, regulate agricultural runoff entering the lake’s tributaries and fully implement existing management and long-term conservation plans.

The Center also called on the European Union, Germany, UNDP and other international partners to sustain their engagement with Lake Sevan beyond previous project cycles.

Saad Kassis-Mohamed, Chairman of the Saad Kassis-Mohamed Center, said the lake should be treated as a national asset whose protection requires sustained action. He described the 100,000-litre shoreline clean-up commitment as a contribution to restoration, while stressing that the lake’s long-term condition depends on action across the wider watershed.

Marcine Graham, Executive Director of the Center, said international support had helped establish plans and frameworks for Lake Sevan, but argued that implementation must now move faster. She said the lake needed practical action on untreated sewage, agricultural runoff and shoreline pollution, not only long-term institutional planning.

The 100,000-litre pledge will not, by itself, solve Lake Sevan’s environmental crisis. Its significance lies in drawing attention to the gap between conservation strategies and visible, measurable action on the ground. For Lake Sevan, the test is no longer whether the risks are known. They are. The test is whether the lake’s protection can move from plans and commitments to enforcement, infrastructure and sustained restoration.

The Saad Kassis-Mohamed Center is an initiative of the WeCare Foundation, Cape Town. The Center works on issues linked to environmental injustice, rights protection and institutional failure, and says it engages with international mechanisms on behalf of affected communities.
