Kenya's Inland Waters and Wetlands

Dynamic ecosystems in constant temporal and spatial flux, supporting biodiversity and vital ecosystem services

Kenya's wetlands, as defined by the EMCA 2009 Regulations, are areas seasonally or permanently flooded by water that support specially adapted plants and animals, including swamps, marshes, peatlands, and shallow marine zones. These ecosystems provide critical services such as water regulation, biodiversity conservation, fisheries support, and cultural value.

Kenya's drainage is divided into six main basins: Lake Victoria (North and South), Ewaso Ng'iro North, Tana River, Athi River, and Rift Valley, each hosting significant wetlands like Yala Swamp, Lorian Swamp, and the Tana Delta. While these basins support livelihoods, agriculture, and energy needs, they face growing threats from land-use change, pollution, habitat degradation, and overexploitation.

Why It Matters

  • Kenya's inland waters and wetlands regulate flooding, recharge aquifers, and underpin agriculture, fisheries, and pastoral livelihoods.
  • Ramsar sites such as Lake Nakuru and the Tana Delta concentrate waterbirds, hippos, crocodiles, and unique fish faunas found nowhere else.
  • Land-use change, pollution, abstraction, and invasive species mean wetland health depends on coordinated catchment-scale management.
