Water rises to top of Syrian Agenda

As the Syrian capital Damascus braces itself for another exceptionally cold winter week, severe water shortages as a result of climate change is leaping to the top of the government’s priorities. UN and Syrian government officials warn that that the water crisis coupled with environmental degradation is likely to worsen over the coming years. Torrential rains in Damascus that have overwhelmed drainage systems and turned the desultory trickle of the Barada river into a torrent are just one indicator of the mounting crisis.

Increased rainfall is doing nothing, however, to alleviate the country’s water shortage. “A study of rainfall over the past 25 years in Syria shows that the intensity is increasing, but the actual levels are either constant or, in some cases, decreasing,” The National quotes Faris Asfari, an agricultural engineer involved in compiling a detailed report on climate change in Syria, who consults for the UN as saying. “Increasingly the rain is torrential and that actually causes severe damage, especially to soil. It has a severe impact on the sustainability and productivity of the land it adds to desertification problems.”

Similarly, Jordan recently reported to the the United Nations Framework Convention on Climate Change (UNFCCC that its water resources will be depleted by climate change even if the kingdom witnesses an increase in precipitation. The report warned that climate change will severely impact the quantity of monthly surface water runoff. It that if current rainfall levels increased by 20 per cent, it would not compensate for the water lost due to the expected rise in temperatures.

A Syrian government report compiled for last month’s environment summit in Copenhagen concluded that most Syrian cities were suffering from shortage of water as a result of reduced rainfall, severe drought and more frequent dust storms. As a result, some 300,000 people in the eastern region, once a thriving farming area have been forced off their land to mostly become internal refugees in Damascus. The government report warns that such dislocations are prompting a decline in standards of health and education. Residents in the central governorate of Hama say drought has dried up the Al Assi River whose water serviced the Al Qantara Hydrostation. They now depend on local wells available only at depths of 600 meters where it contains contaminants that make it unsafe for drinking.

Syrian officials say the situation is further aggravated by the absence of agreements, primarily with Israel, on how to equitably share inadequate water resources. Israel draws some 15 percent of its water supply from the Golan Heights conquered from Syria in 1967. The Heights run up to the eastern shore of the Sea of Galilee, Israel’s only freshwater lake, and include significant parts of the Jordan River’s catchment area. Control of water resources, and Israel’s insistence that it retain sovereignty over the Sea of Galilee, have been one of the main stumbling blocks in failed peace talks.

Nonetheless, environmental scientists say the Syrian government bears significant responsibility for water shortages and land degradation, with decades of mismanagement, corruption and inefficiency exacerbating existing problems. Land not fit for cultivation was widely farmed in the 1980s as part of a food security policy and although it was stopped in the 1990s, severe damage was done.
Syria uses 90 percent of its water for mostly inefficient irrigation. “Irrigation systems here are only 38 per cent efficient, which means we throw away 62 per cent of all of our national water supplies before it even reaches the crops,” Yousef Meslmani, the national environmental affairs project director with the United Nations Development Programme (UNDP) in Damascus told . The National. “We have irrigation channels built on soluble rock – which is the worst thing you can do – and the engineers told them it was bad idea, but they did it.”

Abu Dhabi 2100: under water?

The National reports that a UAE government commissioned report has warned that the UAE could lose up to six per cent of its populated and developed coastline by the end of the century because of rising sea levels.




The report said a rise of one meter, the best case scenario, was not “unlikely.” It would put 1,155 square kilometers of the country’s coast under water by 2050; nine meters, the worst case, would submerge most of Abu Dhabi and much of Dubai.




A one meter rise would cost Abu Dhabi more than 10sq km of built-up area and more than 100 sq km of urban greening.
The report, Climate Change: Impacts, Vulnerability and Adaptation was commissioned by the Environment Agency – Abu Dhabi (EAD) and compiled by the Stockholm Environment. It warns that unless future development planning accounted for the changes, there would be unacceptable economic damages for the UAE’s coastal zones.
The International Panel on Climate Change, the world’s most authoritative scientific body on the subject, estimates that sea levels will rise by between 0.37 metres and 0.59m by the turn of the century. The actual fluctuation will depend on a number of variables, including how much global temperatures rise, and how that will affect glaciers and snow cover on polar caps.
