At a time of population growth and increasing concern about climate change, countries such as the UAE should look at ways to limit demand for water, a leading expert has said.
While discussions concerning water often centre on how to maintain or increase supply, Prof David Hannah, a Unesco chairman in water science at the University of Birmingham in the UK, said that was just part of the equation.
Speaking to The National ahead of taking part in a World Majlis to be held at Expo 2020 Dubai on World Water Day on Tuesday, March 22, he said progress could be made by reducing water demand from agriculture and changes to individual behaviour.
We really need to consider the demand side. That’s particularly important given the population has grown
Prof David Hannah
“We really need to consider the demand side,” he said. “That’s particularly important given the population has grown.”
He noted daily water use in the UAE averages 550 litres per person, “one of the highest” figures globally.
Greater efforts to re-use water and behavioural change could help to limit demand, Prof Hannah added, as could regulation to encourage water conservation and the need to consider the cost of water.
In the region as a whole, Prof Hannah noted agriculture consumed large quantities of water, accounting for as much as 70 per cent of demand, compared to 20 per cent for households and 10 per cent for industry.
“A large proportion is used for agriculture,” he said. “How subsidies are provided for water-intensive crops has to be thought through.”
In terms of their own impact, people should consider not just their personal use, but also how their food and other goods, such as clothing, impacts on demand for water as part of an individual’s “global water footprint”, Prof Hannah said.
Demand for water goes up as population surges
Globally, freshwater use has grown several-fold over the past century as the world’s population has increased.
According to OurWorldinData, using figures from the Global International Geosphere-Biosphere Programme (IGBP), total global freshwater withdrawal – water taken from ground or surface resources – was 671.31 million cubic metres in 1901.
In 2014, the last year for which the IGBP compiled figures, the total was 3.99 trillion cubic metres.
While water use in the UAE is several times that in many other nations, efforts have been made to limit consumption for a number of years.
For example, in 2010 the Environment Agency Abu Dhabi launched a “Watersavers” campaign to install water-saving devices in the emirate’s domestic, government, educational, religious and industrial buildings.
The UAE has also become an important centre for hydroponic agriculture, in which plants are grown in nutrient solutions instead of soil and water use is a fraction of that of conventional agriculture.
Amid high demand for water, the effects of climate change add another layer of uncertainty because, Prof Hannah said, it was clear temperatures in the region would increase, but forecasts for precipitation range from a 20 per cent decrease to a 10 per cent increase.
Putting people in the water cycle
At Expo 2020 Dubai, Prof Hannah will be giving a speech at Terra – The Sustainability Pavilion on the Price of Water.
As part of his role holding a Unesco chair in water science, he is keen to improve education about the water cycle, the term for how water moves and is stored in the different atmosphere, land and ocean compartments of the cycle.
He is also keen that the influence of people on the water cycle is recognised.
An international research project Prof Hannah was involved with looked at 450 diagrams of the water cycle in a range of media, including textbooks and scientific articles.
It was found that 85 per cent of diagrams did not depict people in the water cycle, despite the significant role humans have, while just two per cent of diagrams featured climate change and two per cent pollution.
“That made us feel the water cycle is misrepresented, because people do have an effect on the water cycle,” he said.
“There’s a lack of awareness of how people relate to water. That gives us a false sense of security about current and future availability of water.”
The effects people are having on water-related systems are significant but often not widely appreciated, he indicated, because wetlands are disappearing three times as fast as forests but do not get as much attention.
As well as water quantity, he said water quality was a critical issue, with an estimated 1.8 million people dying each year because of polluted water.

Tearful appearance
Chancellor Rachel Reeves set markets on edge as she appeared visibly distraught in parliament on Wednesday.
Legislative setbacks for the government have blown a new hole in the budgetary calculations at a time when the deficit is stubbornly large and the economy is struggling to grow.
She appeared with Keir Starmer on Thursday and the pair embraced, but he had failed to give her his backing as she cried a day earlier.
A spokesman said her upset demeanour was due to a personal matter.

'Young girls thinking of big ideas'
Words come easy for aspiring writer Afra Al Muhairb. The business side of books, on the other hand, is entirely foreign to the 16-year-old Emirati. So, she followed her father’s advice and enroled in the Abu Dhabi Education Council’s summer entrepreneurship course at Abu Dhabi University hoping to pick up a few new skills.
“Most of us have this dream of opening a business,” said Afra, referring to her peers are “young girls thinking of big ideas.”
In the three-week class, pupils are challenged to come up with a business and develop an operational and marketing plan to support their idea. But, the learning goes far beyond sales and branding, said teacher Sonia Elhaj.
“It’s not only about starting up a business, it’s all the meta skills that goes with it -- building self confidence, communication,” said Ms Elhaj. “It’s a way to coach them and to harness ideas and to allow them to be creative. They are really hungry to do this and be heard. They are so happy to be actually doing something, to be engaged in creating something new, not only sitting and listening and getting new information and new knowledge. Now they are applying that knowledge.”
Afra’s team decided to focus their business idea on a restaurant modelled after the Leaning Tower of Pisa. Each level would have a different international cuisine and all the meat would be halal. The pupils thought of this after discussing a common problem they face when travelling abroad.
“Sometimes we find the struggle of finding halal food, so we just eat fish and cheese, so it’s hard for us to spend 20 days with fish and cheese,” said Afra. “So we made this tower so every person who comes – from Africa, from America – they will find the right food to eat.”

What is a robo-adviser?
Robo-advisers use an online sign-up process to gauge an investor’s risk tolerance by feeding information such as their age, income, saving goals and investment history into an algorithm, which then assigns them an investment portfolio, ranging from more conservative to higher risk ones.
These portfolios are made up of exchange traded funds (ETFs) with exposure to indices such as US and global equities, fixed-income products like bonds, though exposure to real estate, commodity ETFs or gold is also possible.
Investing in ETFs allows robo-advisers to offer fees far lower than traditional investments, such as actively managed mutual funds bought through a bank or broker. Investors can buy ETFs directly via a brokerage, but with robo-advisers they benefit from investment portfolios matched to their risk tolerance as well as being user friendly.
Many robo-advisers charge what are called wrap fees, meaning there are no additional fees such as subscription or withdrawal fees, success fees or fees for rebalancing.
