Investing as little as 0.16 per cent of the world’s gross domestic product or $198 billion per year could give half a billion people regular access to safe drinking water within four years, a U.N. official said on Friday.
That would halve the number of people who risk serious illness and death on a daily basis, the United Nations Environment Programme said.
The findings are presented in the U.N.’s Green Economy report, which also warns that if the global community continues to ignore water services investments, demand for water risks outstripping supply by 40 per cent before 2030.
UNEP spokesman Nick Nuttall said the world total of people without access to safe drinking water currently totals around 1 billion people.
According to the report, people living in countries such as Cambodia, Indonesia, the Philippines and Vietnam are particularly prone to catching waterborne diseases because of the poor water sanitation there.
“Accelerated investment in water-dependent ecosystems, water infrastructure and water management, coupled with effective policies, can boost water and food security, improve human health and promote economic growth,” said U.N. Under Secretary General and UNEP Executive Director Achim Steiner.
Prof. Mike Young, lead author of the water chapter of the report, said that “without this investment and policy reform, water supply crises will become increasingly common.”
UNEP said that more water productivity, recycling, new dams and desalination plants could largely help avoid increased drinking water scarcity but that money also needs to be put toward infrastructure, water policy reforms and technologies.
The findings were presented during this week’s World Water Week in Stockholm.
