Thanks for sharing Dear.
Because of this problem, new techniques to water plants have been developed.I hope they will be useful.

Luetfen, what exactly are the new techniques, Muejde?

Dwindling farm water threatens Turkish disaster
By Nicholas Birch in Karapinar
Published: 24 September 2007
An environmental catastrophe is threatening central Turkey, once the country's breadbasket, where farmers are depleting the water table after the hottest summer in living memory.
A shepherd since his childhood, 60-year-old Kamil Gurel reckoned he knew the terrain on the southern edge of Turkey's vast Konya plain as well as anyone. Until one moonless night recently, when walking his flocks back home, he fell at least 40 metres down a sink-hole that hadn't been there the week before.
Luckily, he survived. But like the dozens of other sink-holes to have formed in recent decades, the chasm Mr Gurel fell into is "a warning sign of an impending catastrophe", according to Tahir Nalbantcilar, the head of the Chamber of Geological Engineers in the regional capital of Konya.
On the Konya plain – an area more than twice the size of Wales that stretches south from Ankara almost all the way to the Mediterranean – water is the region's biggest problem.
Mr Nalbantcilar described it as a matter of simple arithmetic. Devoid of rivers, hemmed in by mountains on all sides, the plain has no source of water other than groundwater. For the past 40 years, farmers have sucked it up faster than rain can replenish it. The result is a water table that is sinking fast.
"We used to pull water by hand out of wells five metres deep," said Tahsin Ata, a farmer in the small village of Cirali, up the road from Mr Gurel's sink-hole. "Now you have to go 80 metres down."
The drop in water table levels – averaging 27 metres across the plateau in the last 25 years – has had disastrous effects. Dozens of lakes have disappeared, taking their wildfowl with them. Others, including the 1,500sq km salt lake that lies in the centre of the plain, are shrinking fast.
"If things go on as they are now," Mr Nalbantcilar said, "the whole plain will be a desert within 30 years."
Climate change is part of the problem. Always low, rainfall over the plateau now appears to be decreasing.
A recent UN report described the region as acutely sensitive to global warming. But the real source of the depletion is to be found the length of the road connecting Konya to Mr Gurel's home district of Karapinar: field after field of sugar beet and maize, glistening with water under a burning sun.
This area used to be known as Turkey's granary. But with subsidies on wheat whittled down to nothing, local farmers have increasingly turned to thirstier crops to earn a living. Beet – state-subsidised as it is in Europe and the US – needs five times more water than wheat, and its spread has sparked well-digging across the plateau.
Many farmers are aware that what they are doing isn't sustainable, but believe they have no choice.
For Cagri Deniz Eryilmaz, an expert with WWF in Ankara, an organisation formerly known as the World Wildlife Fund, the solution lies in an integrated water and agricultural policy covering the entire plain. For two years, WWF has been negotiating with government agencies and farmers for more sustainable agricultural practices.
Mr Nalbantcilar, meanwhile, identified unwieldy bureaucracy as the main problem. "There are 15 different agencies dealing with water, all of them jealous of their prerogatives", he said.
Both Mr Eryilmaz and Mr Nalbantcilar, however, were optimistic the coming desert could be held back.

Quoting Roswitha: Luetfen, what exactly are the new techniques, Muejde? |
Thanks Roswitha. I remembered reading this article actually in the paper..Thanks anyway.
It will be nice to know what they are thinking as a solution though.
I am hoping that there is one!

Hi - I have heard of a technique they are using on the farms in Israel, it is a drip irrigation. Rows of hose/pipes along farm that continuously drip small droplets of water close to the plant. Just one drop dripping onto one plant. The problem with conventional watering is when large amounts of water that are poured (with hosepipe) onto the earth something like 70% evapourates back into the atmosphere and only 30% is actually getting down into the earth. With the drip technique, all the water gets right down into the earth and it saves a huge amount of water being evapourated.

Hope this may through some light on the technique.

Thanks for the info Cacik.
However, we are talking about a place bigger than Israel itself. There might be a huge cost of changing the entire irrigation system. And of course, getting the water from the soil itself; new drillings; pumps. I dont even want to think about it!
Thanks anyway

Actually I think you may have not understood what I meant and what the technique refers to. An individual farm could use the drip irrigation system. Not Turkey building a system for the entire country !! Instead of pulling a hosepipe along and spraying water over the plants, you could lay the hosepipe along the ground, small holes in the pipe at certain points and very small drop from each point.
Also, you don't get water from the soil itself, you get water from the same place a farmer would, a tap or channelled resevior waters. It is just transported alongs hosepipes and left on to drip.
An individual farmer could invest in this system for his own farm, or perhaps the government could subsidize farmers who are willing to upgrade their systems and help this country !
