STOCKHOLM – A gift of nature, or a valuable commodity? A human right, or a luxury for the privileged few? Will the agricultural sector or industrial sector be the main consumer of this precious resource? Whatever the answers to these and many more questions, one thing is clear: that water will be one of the defining issues of the coming decade.

Some estimates say that 768 million people still have no access to fresh water. Other research puts the number higher, suggesting that up to 3.5 billion people are denied the right to an improved source of this basic necessity.

As United Nations agencies and member states inch closer to agreeing on a new set of development targets to replace the soon-to-expire Millennium Development Goals (MDGs), the need to include water in post-2015 development planning is more urgent than ever.

The latest World Water Development Report (WWDR) suggests, “Global water demand (in terms of water withdrawals) is projected to increase by some 55 percent by 2050, mainly because of growing demands from manufacturing (400 percent), thermal electricity generation (140 percent) and domestic use (130 percent).”

In addition, a steady rise in urbanization is likely to result in a ‘planet of cities’ where 40 percent of the world’s population will reside in areas of severe water stress through 2050.

Groundwater supplies are diminishing; some 20 percent of the world’s aquifers are facing over-exploitation, and degradation of wetlands is affecting the capacity of ecosystems to purify water supplies.

WWDR findings also indicate that climbing global energy demand – slated to rise by one-third by 2030 – will further exhaust limited water sources; electricity demand alone is poised to shoot up by 70 percent by 2035, with China and India accounting for over 50 percent of that growth.

Against this backdrop, water experts around the world told IPS that management of this invaluable resource will occupy a prominent place among the yet-to-be finalized Sustainable Development Goals (SDGs), in the hopes of fending off crises provoked by severe shortages.

“We are discussing the goals, and most member [states] agree that water needs better coordination and management,” Amina Mohammed, the United Nations secretary-general’s special advisor on post-2015 development planning told IPS on the sidelines of the annual Stockholm World Water Week earlier this month.
