UN warns over water shortfall

The world could suffer a 40% shortfall in water in just 15 years unless countries dramatically change their use of the resource, a UN report has warned.

Many underground water reserves are already running low, while rainfall patterns are predicted to become more erratic with climate change.

As the world’s population grows to an expected 9 billion by 2050, more groundwater will be needed for farming, industry and personal consumption.

The report predicts global water demand will increase 55% by 2050, while reserves dwindle. If current usage does not change, the world will have only 60% of the water it needs in 2030, it said.

Having less available water risks catastrophe on many fronts: crops could fail, ecosystems could break down, industries could collapse, disease and poverty could worsen, and violent conflicts over access to water could become more frequent.

“Unless the balance between demand and finite supplies is restored, the world will face an increasingly severe global water deficit,” the annual World Water Development Report said, noting that more efficient use could guarantee enough supply in the future.

The report, released in New Delhi two days before World Water Day, calls on policymakers and communities to rethink water policies, urging more conservation as well as recycling of wastewater as is done in Singapore.

Countries could also raise prices for water as well as searh for ways to make water-intensive sectors more efficient and less polluting, it said.

In many countries including India, water use is largely unregulated and often wasteful. Pollution of water is often ignored and unpunished. At least 80% of India’s population relies on groundwater for drinking to avoid bacteria-infested surface waters.

In agriculture-intense India, where studies show some aquifers are being depleted at the world’s fastest rates, the shortfall has been forecast at 50% or higher. Climate change is expected to make the situation worse as higher temperatures and more erratic weather patterns disrupt rainfall.

Currently, about 748 million people worldwide have poor access to clean drinking water, the report said, cautioning that economic growth alone is not the solution – and could make the situation worse unless reforms ensure more efficiency and less pollution.

“Unsustainable development pathways and governance failures have affected the quality and availability of water resources, compromising their capacity to generate social and economic benefits,” it said.

“Economic growth itself is not a guarantee for wider social progress.”
