Research summary
الورقة البحثية تهدف إلى تقدير كميات المياه المخصصة لإرواء المساحات الزراعية في المنطقة الساحلية خلال الفترة 2002-2012، في حال استخدام الري الحديث (الري بالتنقيط والري بالرذاذ) بدلاً من الري السطحي التقليدي. اعتمد الباحثان على المنهجين التاريخي والوصفي، وخلصا إلى أن استخدام الري بالتنقيط يمكن أن يوفر 40% من المياه المستخدمة في الري السطحي، بينما يمكن للري بالرذاذ أن يوفر 28%. كما تناولت الدراسة الفاقد في شبكات الري الحكومية وآليات التسعير المناسبة. أظهرت النتائج أن هناك عجزاً في استرداد تكاليف التشغيل والصيانة لأراضي المزارعين المستفيدين من مياه شبكات الري الحكومية، حيث تبلغ التكلفة الفعلية للهكتار الواحد 21500 ل.س، بينما يتم تحصيل 3500 ل.س فقط. توصي الدراسة بضرورة التحول إلى الري الحديث لتقليل الهدر في المياه وتحسين كفاءة استخدامها، بالإضافة إلى تعديل سياسات التسعير لتغطية التكاليف الحقيقية.
Critical review
الدراسة تقدم تحليلاً شاملاً لمشكلة هدر المياه في القطاع الزراعي في المنطقة الساحلية وتقدم حلولاً عملية من خلال التحول إلى الري الحديث. ومع ذلك، يمكن أن تكون الدراسة أكثر شمولاً إذا تناولت أيضاً العوامل الاجتماعية والاقتصادية التي قد تؤثر على تبني المزارعين للتقنيات الحديثة. كما أن الدراسة تعتمد بشكل كبير على البيانات التاريخية دون تقديم تحليل مستقبلي مفصل لكيفية تأثير التغيرات المناخية على الموارد المائية. من الجيد أيضاً أن تشمل الدراسة تجارب ميدانية لتقييم فعالية تقنيات الري الحديثة في السياقات المحلية المختلفة.

Because rainfall in the coastal area is high and water projects are nearly missing, we think it is important to make use of available water resources. In order to predict future rainfalls and suggest proper management of resources, we created a mathe matical model linking rainfall amounts between demand (population, agricultural and industrial) on water resources during the period (2000-2012). Results show the following: 1. Rainfalls decreased during the period ( 2002-2012) at an annual rate of (1.84%). 2. Demand on water resources increased during the period (2002-2012) at an annual rate of (3.41%) of the population demand, and (3.47 %) of the agricultural demand, and 6.25% for industrial demand. 3. There is a surplus of available water resources and the size of demand for them, with the surplus decreasing during the period (2002-2012) at an annual rate (2.97 %). 4. The estimation of the surplus between the amount of available water resources and the size of the demand for them will decrease in 2023 from what it was like in the year 2013 at an annual rate (-3.23%).
This research deals with evaluating the financial performance of Syria International Islamic Bank during the period 2008-2012 through the presentation, analysis and interpretation of the most important components of the financial statements of the ba nk, which include: analysis of assets (uses of funds). Analysis of liabilities (sources of funds). Analysis of own resources, namely: (analysis of capital stock paid, analyzing reserves, retained earnings analysis, analysis of property rights). Analysis of external resources (deposits). Investment analysis. Analysis of revenue. Profitability Analysis. Analysis of financial solvency. Using statistical methods appropriate average annual change, and the average growth rate, and simple regression, was reached following results: 1 - grow assets (uses of funds) at an increasing rate, and this demonstrates the ability of Syria International Islamic Bank to generate future cash flows, including it with high efficiency in its financial performance. 2 - grow liabilities ( sources of funds) increased continuously, and this indicates that the bank is the process of attracting deposits and development, as a result of the confidence gained by depositors which will reflect positively on its financial performance. 3- Revenue achieved high growth rates in most of the years of study and was Murabaha istisna, and leave ended Bittamleek formulas are used within the revenue from financing activities. 4 - low rates of investment grow with time in most years of the study, where there is an Islamic investment Kalmzarah formats and Musaqah. and the other did not enter the bank yet, as there are some formulas entered the bank in a limited way Kalmdharbh and participation.
The research aims to study the reality of olive production in the province of Latakia, and of time-series extends from the year 2002 to the year 2013, and based on the indices, growth rates, and simple regression, has been studying the reality and the evolution of olive production, and areas planted with olive trees, and the number of trees olive during the period studied, and it was the most important results: *The relationship between the olive production and the time during the period (2002- 2013) is a strong and positive relationship, where 73% of the developments in the production of olive explained by changes of time, and the rest is due to the influence of other factors not included in the model. *The relationship between the cultivated olives space and time during the period (2002-2013) is a very positive and strong relationship, where 87.3% of the developments in the areas cultivated with olives interpret the changes of time, and the rest is due to the influence of other factors not included in the model. *The relationship between the olive trees and the time during the period (2002-2013) is the relationship between positive and very strong, since 89% of the developments in the olive trees explained by changes in time, and the rest is due to the influence of other factors not included in the model.
This study was conducted in the Syrian coastal region, and the honey samples have been collected from eight different sites belonging to the provinces of Latakia and Tartous during the autumn of 2012. Their content of heavy metals (zinc, copper, le ad & cadmium) was estimated by Atomic Absorption at the Higher Institute for Environmental Research at Tishreen University. The results showed that zinc concentration in the bee honey samples ranged from 2.86 to 12.64 mg / kg (mean 7.98±3.67), and copper ranged from 0.125 to 0.652 mg / kg (mean 0.328±0.176 ), lead ranged from 0.084 to 0.378 mg / kg (mean 0.205±0.112), cadmium ranged from 0.0002 to 0.0132 mg / kg (mean 0.0053±0.0052). The results indicated that the largest amounts of heavy metals were found in honey sample taken from the apiary which is located at the eastern entrance of Latakia city (near Joud factory), while the lower concentrations of zinc and lead were in Banias area (Wadi Al Saqi), and the least concentration of copper was in Safita area, and of cadmium was in the Gablah area (Bani Qahtan Castle).Comparing elements concentration in the studied honey samples, Zinc concentration was found to be the highest, followed by copper, lead and then finally cadmium.The results of statistical analysis indicated the existence of significant differences between the studied sites during the autumn of 2012.
Drought is one of the most important challenges facing sustainable development in eastern Mediterranean regions, where water resources are already limited and ecosystems are fragile. Sums of weighted standardized monthly precipitation anomalies were used to assess annual drought intensity, frequency and spatial extent in five climatic stations located in Syrian coastal region during the period 1966-2008.Changes in drought intensity were detected using trends with Mann – Kendall test. Results show that drought occurs with high frequency over all parts of the coastal region(up to 35% in some parts),but with different intensities.Extreme drought can hit all regions in some years as happened in 1972-1973. Moreover drought may strike the same region for three consecutive years (1988-1991). Also the results show an increasing tendency in drought intensityrelated to the decreasein drought index values (between 0.29-0.96). This can have serious ecological and economic consequences and will pose an increasing challenge to agriculture and the management of water resources in this region.
