Iraqi water expert warns water hyacinth threatens Tigris and Euphrates

BAGHDAD, Iraq — An Iraqi water specialist has warned that the rapid spread of water hyacinth across the Tigris and Euphrates rivers poses a direct threat to Iraq's water security and environment. Murtaza al-Janabi said the invasive plant forms a dense layer on the water surface in a short period, blocking sunlight, reducing dissolved oxygen levels and damaging biodiversity and fish populations. According to the specialist, the plant slows river flow, lowers the efficiency of irrigation projects and raises maintenance and operating costs. He added that it also creates breeding conditions for mosquitoes and other pests, creating public health risks. Al-Janabi called for a national plan combining continuous monitoring, mechanical cleanup and biological controls, along with stronger coordination among state agencies, academic institutions and civil society. He stressed that early intervention is cheaper and more effective than action taken after damage has spread. The water hyacinth is among the world's most hazardous invasive aquatic plants. The expert warned that falling water flows and rising temperatures could intensify its pressure on Iraq's water resources.
