UNEP says Mongolia faces critical water shortfall
According to the "Urban Water Vulnerability to Climate Change in Mongolia" report, extreme temperatures and natural disasters such as droughts, flooding and heavy snowfalls are becoming more frequent and annual average temperatures have increased by 2.1°C since the 1940s.
"Mongolia's temperature has already risen by more than 2°C in the last 70 years. The study's climate scenarios suggest that the country will have to get used to having much less water in the future," says Dr Z Batbayr, Deputy Director of Mongolia Water Authority. "The impact of this will be seen across the board, through the degradation of natural environment, ecosystems, and harm to the economy."
The effects of climate change have also been compounded by rapid urbanization, reducing the availability of water for domestic and industrial use.
Mongolia's total water consumption is approximately 540 million m3/year and over 80 percent is consumed by the industrial and agricultural sectors and 20 percent by domestic use. About 80 percent of drinking water comes from aquifers.
Globally, Mongolia is one of 60 countries with limited water resources. There are over 11,000 m3 of water per year for each of the country's 2.4 million people.
"If the status quo for water management in Mongolia continues, the country will not be able to provide sustainable water resources for its population under future climate change," says Dr Young-Woo Park, UNEP Regional Representative for Asia and the Pacific. "Steps need to be taken now so that Mongolia adapts to its changing environment, and I am glad that the Government has plans to act based on the findings of the report."
The situation is particularly serious in urban areas like the capital of Ulaanbaatar, where nearly 40 percent of the country's population resides and where increasing demand and pollution is exerting added pressure on water supplies, sanitation and other public services, adds the report. .
In Ulaanbaatar 50 percent of the one million population live in informal settlements with a low-level of public services. The daily water consumption is only about 5-10 litres per capita per day, and very few are connected to the city's water distribution network.
Currently, water is being withdrawn faster than the rate of discharge in the city, where groundwater tables have shown a marked decline in the past 50 years.
A large part of the water resources for the city comes from the Tuul River, where continuing ecosystem degradation will prove extremely costly in terms of water and other services lost, the report says.
Overall, improved conservation of the Upper Tuul ecosystem is estimated by the report to be worth some USD979 million through the provision of water, tourism, herding, and forest products.
The report makes five key adaptation recommendations for Mongolia:
Develop an Integrated Urban Water Management plan for the Tuul River Basin, with active planning and management of land use and human activities;
Increase investment and rehabilitate existing water supply networks for the domestic water supply. This should include raising public awareness about saving water, building water recycling plants, and improving the management of water supply utilities;
Take steps to reduce the population's vulnerability to extreme weather events, such as improving existing flood protection systems, install an early warning system, review housing and settlement plans, and raise public awareness about extreme weather events; and
Do more to improve water quality, particularly through the rehabilitation of wastewater treatment plants, especially in Ulaanbaatar.
