Lake Turkana National Parks

Africa, Kenya · Natural site · UNESCO World Heritage property #801

High ConcernConfidence: Supportedas of October 15, 2026

Significance

Lake Turkana National Parks comprises three parks around Lake Turkana in Kenya's Rift Valley: Sibiloi, South Island and Central Island National Parks. UNESCO describes the lake as a saline desert lake whose Koobi Fora fossil deposits include evidence of early hominids, and whose parks serve as a breeding area for Nile crocodiles, hippopotamuses and venomous snakes and as a stopover for migratory birds. The property covers 161,485 ha within a lake basin of about 7 million ha, was inscribed in 1997 (boundaries modified in 2001) under natural criteria (viii) and (x), and has been on the List of World Heritage in Danger since 2018.

Current Status Rationale

Historical context is recorded in the events timeline; this classification rests on present conditions and the most recent credible evidence. As of the 2026 Committee decision (48 COM 7A.52), the property remains on the List of World Heritage in Danger, Kenya had asked for its removal, and the Committee found progress on only three of the 16 indicators in the Desired State of Conservation for Removal (DSOCR) and limited progress on the 2020 mission recommendations. The Committee also noted that lake levels are rising but said this does not resolve its concerns about cumulative impacts from developments in the Omo-Turkana Basin, and it regretted the lack of updated information from Ethiopia on Omo Basin projects. The evidence on the lake itself is not uniform, which is why this is stated openly: IUCN's 2025 Outlook says satellite data showed the lake fell about two metres during Gibe III reservoir filling and that lake levels were 0.7 m higher in January 2024 than January 2021, with the rise submerging terrestrial habitat and reaching the site's building infrastructure; a State Party document responding to Decision 47 COM 7A.13 states that the anticipated impacts of the Omo dam construction on the lake's water levels have not been observed; and Mongabay reports that scientists give differing explanations for a large rise over about 15 years. Non-hydrological pressures are also documented: IUCN rates poaching, other human disturbance and the damming of inflowing rivers as High or Very High threats; illegal grazing is described as most acute at Sibiloi, where the State Party reports law enforcement personnel rose from 19 to 62 in 2025. Against that, there are real, documented management responses (Management Plan 2018-2028, an adopted DSOCR, increased staffing, community engagement, Norwegian-funded corrective-measure support noted by the Committee in 2025). Confidence is Supported rather than Confirmed: the Danger List status and Committee findings are directly confirmed by UNESCO, but the 2026 state of conservation report page could not be retrieved, the cause and effect of lake-level change is contested between sources, and the High/Critical boundary is a judgment call. Confidence does not alter the status.

Serious, currently active threats are documented, or major historical damage remains substantially unrepaired. Credible sources support this status, with some limits on corroboration.

Threat Categories

Environmental / Climate

The Committee inscribed the property on the Danger List in June 2018, citing changes to the hydrology of the Lake Turkana Basin, specifically the disruptive effect of Ethiopia's Gibe III dam on the lake's flow and ecosystem, with the Kuraz Sugar Development Project described as a further threat (UNESCO news item; Decision 42 COM 7B.92, which said preliminary hydrological data showed the lake's seasonal fluctuation patterns had already been heavily disrupted). IUCN's 2025 Outlook rates the damming of inflowing rivers as a Very High threat and drought and climate change as a High threat; it states the Omo River supplies over 80% of the lake's inflow (Mongabay says about 90%), that the Gibe III dam was commissioned in December 2016 and has permanently dampened the Omo's annual flood regime, that satellite data showed the lake fell about two metres during reservoir filling, and that the Gibe IV (Koysha) dam was 66% complete as of 2024. The picture since is contested: IUCN says lake levels were 0.7 m higher in January 2024 than January 2021 and that the rise is submerging terrestrial habitat and reaching the site's building infrastructure; the Committee in 2026 noted lake levels are rising but said this does not resolve its concerns about cumulative impacts from Omo-Turkana Basin developments and recalled the need for a Strategic Environmental Assessment (SEA) that separates climate-driven variability from human-caused effects; a State Party document responding to Decision 47 COM 7A.13 says the anticipated impacts of the Omo dam construction on lake water levels have not been observed, and cites a 2021 UNESCO-UNEP-DHI study projecting wetter, more variable hydrology under climate change; Mongabay reports the lake has risen about 8-10 m over roughly 15 years and that scientists offer differing explanations. A pre-dam 2012 modelling study (Velpuri and Senay) estimated filling could lower the lake by up to 2 m at 95% confidence, and found such changes fall within the lake's natural variability of 4.8 m. In 2026 the Committee also regretted the lack of updated information from Ethiopia on Omo Basin projects including the Kuraz Sugar Development Project and the Gibe IV (Koysha) and Gibe V dams.

First identified: Not established — Long-running, evolving basin-wide concern rather than a single event; the Danger List inscription of 28 June 2018 is the earliest dated Committee action cited here, but concerns about Gibe III predate it in Committee decisions that were not all read in this pass.

Conservation / Structural

In 2021 the Committee (Decision 44 COM 7A.47) added poaching and encroachment to the justification for Danger listing, noting a long-standing threat causing 'steep decline and local extinctions of wildlife populations'. UNESCO's 2021 state of conservation page, summarising the March 2020 Reactive Monitoring mission, says several flagship species including Grevy's zebra, reticulated giraffe and lion are no longer present in the property, and that implementation of the 2018-2028 Management Plan was limited by financial and human resource constraints. In 2026 the Committee expressed concern that many key 2020 mission recommendations remain unimplemented or significantly delayed (a site-specific Biodiversity Action Plan, a scientific grazing study and reduction strategy given high livestock numbers in wildlife corridors, co-managed hydrological and limnological monitoring, a national master plan for development around the lake, and a buffer zone) and asked Kenya to consider bringing the three components under one management unit. UNESCO's 2024 state of conservation page lists threats including illegal activities, land conversion, livestock grazing, management plan gaps, oil and gas, water infrastructure and conflict between local communities and park management. IUCN's 2025 Outlook rates poaching and hunting and other human disturbance (destruction of crocodile nests) as High threats and says human population pressure and competition for resources are fuelling local conflict, including a report of 22 fishermen killed near Todenyang by armed militia from across the Ethiopian border (IUCN says 'reports indicate' this; the underlying report was not identified or independently verified here). IUCN rates the property's values as High Concern with a Deteriorating trend, rating rare and endangered fauna as Critical (trend data deficient). Positive developments are also recorded: the Committee in 2026 commended Kenya for implementing the Management Plan, adding staff at Sibiloi National Park, expanding community engagement and completing the 2025 National Wildlife Census, and a State Party document reports law enforcement personnel at Sibiloi rose from 19 to 62 in 2025.

First identified: Not established — Chronic, multi-year concern; the Committee formally added poaching and encroachment to the Danger listing justification in 2021 (Decision 44 COM 7A.47), but no single start date is established from the sources read.

  2. 2016-12
    Gibe III dam on the Omo River commissioned

    IUCN's 2025 Outlook states the Gibe III dam in Ethiopia was commissioned in December 2016 and has dampened the Omo's annual flood regime permanently. Mongabay reports construction began about 2006 (two years before 2008) and that reservoir filling began in 2015, so sources differ on the timing of filling versus commissioning.

    Property inscribed on the List of World Heritage in Danger

    At its 42nd session in Manama the Committee inscribed the property on the Danger List (Decision 42 COM 7B.92), citing changes to the Lake Turkana Basin's hydrology and the disruptive effect of Ethiopia's Gibe III dam, the Kuraz Sugar Development Project (described as a further threat), while also noting potential impacts of the LAPSSET Corridor Project. The decision noted the Strategic Environmental Assessment due by 1 February 2018 had not been commissioned.

    Reactive Monitoring mission to the property

    A Reactive Monitoring mission took place on 6-11 March 2020 (IUCN could not attend because of COVID-19). UNESCO's 2021 state of conservation page records that it could not finalise corrective measures or the Desired State of Conservation for Removal because Ethiopia did not respond to Kenya's invitation, and that it confirmed continued poaching and encroachment.

  9. 2026
    Decision 48 COM 7A.52 retains property on Danger List

    At its 48th session in Busan the Committee decided to retain the property on the Danger List, noting Kenya had asked for removal but that progress covered only three of the 16 DSOCR indicators and progress on the 2020 mission recommendations was limited. It urged Ethiopia and Kenya to initiate the SEA as a priority and requested an updated report by 1 February 2027. The property is also in the list of 52 properties retained under Decision 48 COM 8C.2. Exact adoption date not shown on the decision pages.

Digital Preservation Index

Overall coverage: Limited — Only a small amount of public digital documentation could be found.

Only one of five categories (archival_records) has publicly accessible evidence found in this pass, which is the limited tier by the rubric (1 category). The evidence is documentary rather than visual or immersive: no property-level 3D model, virtual tour or substantive professional photo archive was found. UNESCO's property gallery showed a single thumbnail image, which was not treated as a substantive photo archive, and Wikimedia Commons could not be opened in this pass. Academic_scholarly is marked false: the only scholarly item opened (a 2012 pre-dam hydrology modelling paper) concerns the lake rather than documenting the property, and the African Fossils virtual lab hosts 3D models of fossils found mostly at Lake Turkana without stating they come from within the inscribed parks, so it is a specimen collection and not documentation of the property; both are listed as adjacent material only and are not counted. Coverage is also uneven across the three components; nothing found documents South Island or Central Island specifically. This reflects what was publicly findable, not necessarily what exists in unpublished archives or in scholarship not searched for in this pass.
