Groundwater levels in decline
The
declining level of groundwater is set to challenge the UAE's policy of
artificially maintaining greenery. "One of the main challenges facing
the water resources is saving water in the agriculture sector,” said
Majid Al Mansouri, the Secretary-General of the Environment Agency of
Abu Dhabi (EAD).
Mansouri was reacting to a United Nations report entitled Environmental
Global Deserts Outlook 2006. The report highlights the UAE as being one
of the most water-imperilled nations in the world.
The report says the country has less than 250 cubic metres of renewable
fresh water per person per year. Given the demands put on such limited
supplies, they are set to decline in coming years. "Government policies
have encouraged and promoted the general ‘greening' of the Emirates'
desert landscape. In 2003, a total of six per cent of the total area of
the Emirate was considered as ‘green and supported by some means of
irrigation',” the official said.

Currently, agriculture accounts for 58 per cent of water consumption.
Most of the water used by agriculture is brackish groundwater. The
country used an estimated 2,108 million cubic metres of water in 1995 –
76 per cent of which came from ground water sources.
The Food and Agriculture Organisation's Aquastat information programme
said that 300 million cubic metres of groundwater was used each year for
crops, while landscape irrigation used 108 million cubic metres (all
treated wastewater). Experts say that very little of this water finds
its way back to underground reservoirs after use, most of the water
simply flows into the sea.
"Given declining water levels, and a general deterioration in
groundwater quality, the protection and conservation of all groundwater
of all quality is of vital importance,” Al Mansouri said. "Maximum water
conservation can be achieved by selecting plants that require the
minimum amount of supplementary watering in a given area.” The EAD is
looking to make agriculture in the emirate more water-efficient through
conservative irrigation methods and the cultivation of hardy crops.
