Under the blazing sun of northern Tanzania, where shimmering salt flats meet the alkaline waters of Lake Natron, thousands of Lesser Flamingos (Phoeniconaias minor), classified as Near threatened on the IUCN Red List of Threatened Species, gather each year to breed. However, Lesser Flamingos do not breed every year—they often skip breeding altogether during unfavourable conditions, making Lake Natron’s successful breeding seasons even more critical. Designated as a Ramsar site in 2001, it is East Africa’s only regular breeding site for the species, sustaining nearly 1.5 – 2.5 million flamingos, representing 75% of the species global population. Its harsh beauty belies its fragility: one alteration in water flow, salinity and habitat could spell disaster for flamingos and more than 300 bird species, including waterbirds of global conservation importance, that depend on its wetlands and grasslands… Despite its ecological and economic importance, Lake Natron has long been threatened by degradation. This leads to biodiversity loss, unsustainable agricultural practices, deforestation in the catchment and inadequate wetland management practices, among other issues. Further, it has previously faced a serious threat from proposed soda ash mining, which first came to light in 2006, but plans were withdrawn following an international outcry and pressure led by BirdLife International and 56 other conservation organisations from across the globe. Most recently, in early 2025, Ngaresero Valley Company Ltd announced plans to put up a plant with the capacity to extract 1,000,000 metric tonnes…

From May to July 2025, Nature Tanzania, working closely with communities in nine villages surrounding the lake, spearheaded an unprecedented grassroots mobilisation following shocking news and request to contribute to a secretly developed Environmental and Social Impact Assessment process. The villages include Engaresero, Magadini, Gelai Lumbwa, Gelai Merugoi, Loondolwo, Pinyinyi, Wosiwosi, Ilchangit Sapukin and Alaililai. Community members, pastoralists, and elders gathered under the banner “Our Lake, Our Life” to voice their opposition. Following requests from these communities, Nature Tanzania organised 17 meetings where communities discussed the matter and agreed on resolutions. For local Maasai people, the lake is far more than a breeding ground for flamingos—it is a lifeline. More than 65,000 people depend on the lake for their livelihoods, including ecotourism and livestock keeping…

After four months of advocacy, in August 2025, the Tanzanian government announced it will not allow large-scale soda ash extraction at Lake Natron. Officials reaffirmed that the lake’s Ramsar status and its role as the only significant Lesser Flamingo breeding site in East Africa make it too important to risk. Only traditional, small-scale surface collection of soda ash along the shoreline will continue. Responding to the controversy, Deputy Minister for Minerals, Stephen Kiruswa insisted that no licence had been—or would ever be—issued for mining inside Lake Natron. “Only traditional surface collection of naturally occurring soda ash along the lake’s edge is permitted. No large-scale extraction will be authorised,” he said. This official reassurance aligned with community concerns and reinforced the government’s position to preserve the Ramsar-protected site. The recent move by the government aligns with Nature Tanzania’s ongoing work: training young people as bird guides, conducting biodiversity monitoring, and promoting ecotourism as a sustainable alternative to extractive development. The story of Natron is not only about flamingos, but about resilience and rights. It is about communities protecting their heritage, safeguarding natural resources, and governments listening to science and people. It is also a reminder of the power of partnerships – researchers, NGOs, BirdLife International, Nature Tanzania, and local communities standing together.
