Overview

A huge number of lesser flamingos depend on Tanzania's Lake Natron as a breeding site, threatened by a large-scale soda ash development

Three-quarters of the world population of lesser flamingos live and nest in East Africa. All depend on Tanzania's Lake Natron as a breeding site.

Food is plentiful, nesting sites abound – and above all, the lake is isolated and undisturbed.

In 2006, the Tanzanian Government and the Indian company Tata Chemicals put forward proposals to build a large-scale industrial plant to extract soda ash from Lake Natron's water, via a network of pipes across the surface of the lake. New road and rail infrastructure would also be built to serve the soda ash plant.

Thankfully in May 2008 Tata withdrew from the project. But the Tanzanian Government remained committed and the National Development Corporation, a government agency, led a push to find alternative investors.

We believe that the development and associated infrastructure will displace and scatter the 500,000 pairs of lesser flamingos which nest at Lake Natron. It takes very little disturbance to cause an entire breeding colony to abandon its nests. Additionally, the livelihoods of local communities would also be at risk.

In March 2018, the Government of Tanzania announced that they were withdrawing plans to build the soda ash plant at Lake Natron, but would promote an alternative site at Engaruka, some 30 miles (50 km) south of Lake Natron. 

This is good news for the lesser flamingos at Lake Natron.

Why is it worth fighting for?

The number of birds at this site are staggering - there are thought to be between 2.2 million and 3.25m lesser flamingos in the world, of which between 1.5m and 2.5m are found in East Africa where Lake Natron is the only significant and regular breeding site.

Due to habitat loss and contamination, we are already seeing a decline in the global population of lesser flamingos, so the impact on the species could be disastrous if Lake Natron were to become unsuitable for nesting: 75 per cent of the global population of this Globally Threatened Species would be at risk. We therefore need to do all we can to protect this precious place.

Lesser flamingos feed on Spirulina, which is commonly known as blue-green algae (although in fact it is bacteria!). Spirulina sometimes gives Lake Natron a pink colour. It grows only in salty lakes like Lake Natron which is known as a soda lake because of its high concentration of sodium carbonate.

Flamingos live until they are about 40 years old, but only breed every five or six years. Non-breeding birds do not return to breeding sites until they are ready to breed again.

Tourist attraction

The bird spectacle attracts tourists to the national parks of Tanzania, Kenya and Ethiopia.

The tourist industry around Lake Natron alone is worth US$500,000 per annum excluding associated spending. Visits to the area are likely to increase if the soda ash proposal is rejected.

Lake Natron is a wetland of international importance designated under the Ramsar Convention. The lesser flamingo is classified as Near Threatened on the IUCN Red List since 2004.

How you can help

Visit the Think Pink - save Africa's flamingos website for more information, or to donate money towards this campaign.

Visit our the Serengeti webpages for more information about the proposed road which will cut through the National Park and pass close by Lake Natron, putting additional pressure on the flamingos. 

Our position

We believe the development and associated infrastructure for this project will displace and scatter the 500,000 pairs of lesser flamingos which nest at Lake Natron, and therefore must not be built.

It takes very little disturbance to cause an entire breeding colony to abandon its nests. To nest successfully, lesser flamingos require very specific conditions, which Lake Natron provides.

The proposed plant poses major risks to the lesser flamingos from disturbance (including increased populations of nest predators), as well as changes in the water balance and chemistry of the lake.

Soda ash mining also threatens the tourism industry throughout East Africa and the livelihoods of the local people who depend on the lake basin for their sustenance. The legal protection of Lake Natron should be strengthened.

  • March 2013
    We hear reports of enhanced exploration of soda ash at a site known as Engaruka, 40 km from Lake Natron and part of the same ecosystem. The NDC has commissioned core sampling to determine areas rich in soda ash. A team of geologists are drilling holes up to 60 metres and taking samples. Up to seven sample sites have been seen plus more open-type exploration excavating bigger holes. This is causing concern among the local community as it is affecting grazing and cultivated land.
  • August 2012
    A new Cost Benefit Analysis report finds that soda ash mining at Lake Natron is not economically viable. It shows that the projected return on investment over the next 50 years would be a loss of between $44,354,728 and $492,142,797. It also found that support for the project is low with 84 per cent of 175 local community respondents consulted strongly opposed to the project.
  • June 2012
    Tata Chemicals deny any involvement in the current project reiterating that they withdrew from the project in 2009. We submit a brief to the Ramsar Convention in advance of its meeting in Romania.
  • May 2012
    The Lake Natron Consultative Group is five years old. The Regional Commissioner of Arusha, Mr Magesa Mulongo, states that the regional government is committed to fast-tracking the construction of a soda ash factory at Lake Natron, and that the project would create job opportunities and play an important role in boosting the country's economic development.
  • March 2012
    The Tanzanian Minister of Trade and Industry, Mr Cyril Chami, says the government is in talks with Tata Chemicals Ltd to set up a $450 million soda ash factory within the Lake Natron basin, in the Engaruka area.
  • October 2011
    The Director of Environment in the Vice-President's Office, Dr Julius Ningu, says the Tanzania Government position on Lake Natron is to maintain the ecological system so that flamingos continue to breed, and that damaging human activity is prohibited in the area. But at the same time, the Tanzania National Development Corporation and an investment bank undertake a field inspection to look at the prospects for mining.
  • April 2011
    The President of Tanzania orders the Ministry of Mining and Trade to fast track the Lake Natron soda ash project saying the country cannot continue to be poor while its mineral resources remained unexploited.
  • September 2010
    For the first time, it comes to light that the NDC was mandated by the Tanzania Government through a cabinet paper to go ahead with the soda ash plant project way back in 1996. This underscores how committed NDC is to justify the project and find a new co-investor.
  • September 2010
    It emerges that the NDC has commissioned a team of consultants from Dar es Salaam (University Consultancy Bureau) to undertake 'gap analysis studies' on information for the Lake Natron soda ash project – identifying 'what has been documented and what gaps exist which need to be filled before further work is done'. This team has visited a number of institutions in Tanzania and Kenya seeking information, raising suspicion and concern which in reality the consultants may actually be gathering data to inform another Environmental and Social Impact Assessment.
  • June 2010
    The Lake Natron soda ash project remains on the radar of the Tanzania Government as the National Development Corporation (NDC) says it intends to conduct 'a techno-economic study of the Lake Natron soda ash deposits, to explore its viability for commercial exploitation'.
  • June 2010
    The Tanzanian Government relaunch a proposal to build a super highway across Serengeti National Park in Tanzania through Lake Natron. The road, which would link Tanzania with Uganda, Rwanda, Burundi and Congo, was discussed with the World Bank 20 years ago but rejected due to environmental reasons. Now conservationists, the Tourism industry and concerned citizens believe the road threatens the greatest wildlife migration on earth, that of millions of Wildebeest and Zebra, which move between Serengeti and Maasai Mara in Kenya. If this road were built through Lake Natron, it would put immense pressure on the most important breeding site for lesser flamingos in Eastern Africa due to massive traffic.
  • June 2010
    BirdLife receives a grant for a two year project to support conservation activities at Lake Natron. The project will focus on strengthening a local community conservation group (Site Support Group) to promote conservation at the local level. The project will also initiate a number of community projects to contribute to poverty alleviation and improve the livelihoods of the local community through sustainable conservation of natural resources. Working with Government at national, district and village levels, the project will also contribute to the enhanced conservation of the lake ecosystem through the development of an Integrated Management Plan and Wildlife Management Areas.
  • May 2010
    The Tanzanian Government is in the process of creating two Wildlife Management Areas (WMAs) at Lake Natron involving Longido and Ngorongoro Districts. These will empower the local communities to benefit and participate in the management of the resources. A meeting held in May started work on a strategy document to provide a road map for how the WMA process will be finalized. The WMA designation is very welcome and we believe it should be expedited with the involvement of all stakeholders.
  • May 2010
    Tanzania’s National Development Corporation (NDC) is still keen to have soda ash mined at Lake Natron. The NDC has commissioned a hydrological study to examine if there is sufficient water to allow soda ash mining – one of the areas that generated intense criticism in the initial proposal.
  • February 2010
    A Single Species Action Plan (SSAP) for Tanzania's lesser flamingos is in preparation. A workshop brings together government, NGOs (including BirdLife), local community and academics to discuss a draft. The aim of the plan is to stabilize the size and distribution of the national breeding and non-breeding populations at 1.5 million birds in key sites by 2019, through local national and regional action. Tanzania has 13 sites which are important for lesser flamingos. Nine of these, including Lake Natron have no formal protection. The plan takes a holistic view of the threats and needs of lesser flamingos from the time they are hatched at Lake Natron to flying away to other lakes within Tanzania and other parts of East Africa.
  • December 2009
    Membership of the Lake Natron Consultative Group reaches 50, a huge increase from only five institutions in June 2007.
  • September 2009
