The Environmental Problems    

  Mohammed Al Oudat

 

Introduction:

Syria has managed a noticeable progress since the sixties. The individual's share of total local production increased, the average of children's death (under 5 years) decreased from 218 per thousand during the sixties to 41.7 in 1994. The average expected of age became higher and reached about 67 years. Also, the education's levels improved, almost 100% of children attended the primary schools. There was also a noticeable increase of attending secondary schools and universities.

This progress became threatened with the environmental hasards. In fact, the lack of water, the deterioration of agricultural lands, the shortage of public utilities (drainage and sewerage system), plus, air and water pollution, all these problems threaten the capacities of the economical progress and the population's growth. Also, impose high economical and human costs because of illness and early death.

Although Syria has an enough reserves of oil and natural gas, it, relatively, lacks productive lands and renewed water resources. Consequently, the human settlements are located in limited parts of Syria, as well as, the food production, which, mainly, depended on irrigated lands.

The Syrian form of growth, which implied the local sufficiency of food production and fast fabrication, imposed an increasing pressure on natural resources. Actually, since the 60ies, various agricultural investments of intensive production and industrial projects were processed, such as, cement, steel, chemical fertilizers, food industry, power stations, oil refineries and others. This strategy of growth, which was directed to fulfill the needs of the population's growth and its fast increase, did not take into account the importance of preserving the natural resources and its proper use. Therefore, the inappropriate agricultural methods, the populations settlement in limited areas and the unsuitable administration of water usage caused the loss of water resources and the excessive consumption of grasslands. On the other hand, the productive grasslands were transformed into planted lands of non-continuous productive crops. Meanwhile, the excessive use of chemical fertilizers contaminated the superficial water' resources. Besides, the littoral regions went under an increasing pressure, which, negatively, affected the quality of water, and consequently, tourism.

In the urban regions, pollution threatens health, nowadays, because the technological precautions, which decrease the industrial pollution, were scarcely considered. Besides, it was allowed to disregard the International environmental standards and provisions by leaving still the old industries of high pollution working on. Furthermore, the use of old engines' vehicles with its incomplete combustion of fuel increased the air pollution in the urban regions.

The Environmental Pressures in Syria:

Syria is facing an increasing environmental challenge (Frame 1). The average of population's growth is 3.3%, which is one of the high averages in the world. The population of Syria increased from 3.5 millions to 17 millions during the years from 1950 till 2000. The population of the urban cities increased from 4.0 millions in 1980 to over than 8.7 millions in 1998( which equal more than 51% of the total population). This big increase exceeded the growth of municipalities' services. Therefore, plenty of irregular communities were built in the main cities, which lacked the essential foundations and basic services.

- The condition of water resources is very critical. The superficial and groundwater resources are almost consumed. Thus, some regions suffer a severe shortage of drinking water in the arid years and some others lack the safe drainage water because, only, a limited percentage of water is treated. In addition, most of sewerage is thrown away in rivers and seawater, which affected the quality of river's water and seawater.

- Around 40% of cities' inhabitants inhale polluted air due to the high contamination of industries, old cars with improper engines for fuel use, leaded fuel (except Damascus) and oil, which contains a high percentage of sulfur.

- The deterioration of natural resources, such as, the soil erosion, the retreat of natural forests, the loss of biodiversity and the salinity of agricultural lands, form an extended problem.

- Contamination and the unorganized growth threaten the unique heritage of old civilizations in various sites that assist the national economy income through the proceeds of tourism.

The actual condition is reflected in high economical costs, especially, that some of these pressures are unable to be corrected and may affect the growth in the future through the decline of soil productivity and the human's health deterioration. The estimations of the Natural Strategy of Environment in year 2000 clarified that the yearly costs, which result from the environmental collapse in Syria, ranged from 29 to 32 milliards (SP) Syrian pounds in 1997 (690 to 890 millions US dollars). These amounts would increase to ranged from 46 to 54 milliards (SP) in the year 2005 (1.2 to 1.7 milliard US dollars) if no suitable procedures were taken to stop this collapse (Frame 2). The above numbers do not include the costs of deaths, which result from the environmental deterioration like, contamination of water, air and others. Also, other losses, which are difficult to be restricted by quantity, such as, the damage that happen to the ecosystems, the loss of biodiversity, the bad influences of long-term contamination due to the poisoning elements and others are not included with the costs. In fact, the National Strategy of Environment estimated the costs of the environmental hazards about 4% of the national income.

Air quality:

Abu Al Bakaa Abdullah Al Badri, a scientist of the 9th century of Hegira, mentions in his book "Nazhat Al Anam Fi Mahasen Al Sham" that some of Al Sham' charms (the old city of Damascus) are 'the Hawakeer' which look like gardens at the bottom of kasion mountain. Being higher than yazeed river's level, thus, the wheels were used for irrigating these gardens. Basil and roses were planted on purpose, so that the passing breath will carry its aromatic scent into the inhabitants of the city below.

What remained of Al Sham's beauties now? What happened to its air which carried the scent of Damascus people's merits?

The restricted measures, which were made in some principal cities, refer to the improper standard of air, mainly, because of the transport's pollution as in Damascus and Aleppo, besides, the industrial pollution as in Homs, Banias and Tartous. Actually, air became, highly, loaded with concentrated rates of sulfur oxides, nitrogen oxides and carbon monoxide , as well as, loud noises.

Frame 1: The environmental problems in Syria

The Measures showed that the number of days in which the average of the daily primary pollutants (sulfur and nitrogen oxides) in Damascus city increased than the permitted limits, according to the World Health Organization's (WHO) by 25% in 1989, furthermore, this average augmented to 50% in 1995. The same measures were processed in Aleppo and found that the concentration of the primary pollutants was much higher than the permitted limits.

Frame 2: The expected costs of the environmental collapse in Syria according to the National Strategy of Environment's studies.

In addition to the primary pollutants in most Syrian cities that result from the fossil fuel combustion, whether in industry or transport vehicles, there is, also, the smog phenomenon. The smog results from the reaction of the primary pollutants, especially, nitrogen oxides and oxygen with hydrocarbonates and sulfur dioxide under the effect of ultra violet rays. This smog beclouds the sky of cities, mainly, during the morning rush hours. On the other hand, the reaction of the primary pollutants produces a combination of secondary dangerous pollutants, especially, Ozone, and peroxyacetyle nitrate (PAN) which are called photochemical oxidants. Actually, these combinations have severe bad effects on health, such as, throat and brain infections, eye irritation, Asthma, lung infections, cough and others.

Accordingly, the National Strategy of Environment estimated the costs of air pollution in 1997 ranged between 1.2 and 3 milliards SP. Moreover, If no proper procedures are taken, the costs are expected to reach from 3 to 10 milliards SP in 2005 (Frame 2).

The worst air pollution is found in certain cities of Syria. In Damascus, for example, the pollution increases in the eastern region (Bab Shraki, Bab Tuma, Al Tijara and Carajat) and in the old city. The measures indicated that the inhabitants of these areas are permanently exposed to high concentrated of sulfur oxides, nitrogen oxides, carbon monoxide and charcoal smoke. In the region of northern "karajat", the level of the concentrated nitrogen oxides is, permanently, higher than the permitted standard that reaches, sometimes, more than 70% of measurable days. The measures of the year 2000 cleared that Bab Tuma and Tijara are, highly polluted regions, especially, with sulfur dioxide and particulates. The worst pollution is found in the old parts of cities that have narrow streets, crowded transportation and bad ventilation. The reports of the Ministry of Environment in 1998 indicated that the level of sulfur oxides concentration in some streets of old Damascus like, Medhat Basha street and Kishlah cross, reach about 0.13 part per million, especially during day hours (from 11:00 a.m. to 15:00 p.m.). In addition, the level of carbon monoxide, which is a very dangerous poisoning gas, reaches 30 part per million. This level is much higher than the permitted level (9 part per million during 8 hours). In fact, this position reflected an increase of health problems rate, mainly, ophthalmology, pulmonary, E.N.T., dermatology, gastrointestinal diseases and others.

The influence of pollution on the historical heritage:

Air pollution does not, only, affect health, but the archeological heritage as well. The Syrian heritage of old civilizations has an international importance. Four main sites were included within the list of the international heritage (Damascus' old city, Busra, Palmyra and old Aleppo City). Besides, Ebla, Augareet and other sites which witnessed the beginning of the agricultural and irrigation system, the invention of Writing and the establishment of first cities in the human history.

The National Strategy of Environment's report of year 2000 points out the dangerous decline of these ancient sites due to the unawareness of their values and the abuse of its investment. Also, the changes of the surrounding lands' use beside the improper methods of the regular and the irregular building constructions around affect these sites badly.

In addition, the air pollution, harmfully, affects these ancient sites. Actually, Sulfur oxides interact with nitrogen oxides and oxygen under the influence of water vapor and ultra violet rays and transform these oxides into sulfur acid and nitrogen acid which remain as fine mist in the air that are carried by the wind from one place to another. These acids interact with calcium carbonate, which is the essential component of the historical monuments' stones, transforming it into gypsum. The gypsum solidity is technically weak and frail, thus, it breaks and crumbles easily. Therefore, air pollution causes the loss of invaluable ancient monuments. Beside air pollution, dust is another harmful factor, which erodes and ruins these inherited monuments. Also, the charcoal smoke which blackens the archeological monuments. In fact, a big part of these historical monuments are located in crowded areas and heavy traffic, such as Bab Tuma, Bab Sharki in Damascus.

Although the number of cars in Syria is less than 600 thousand cars, which is a small number in comparison to the number of cars in Lebanon (which exceeds 1.2 million cars and more than 1 million cars in Bonn city), transport vehicles are the principle origin of air pollution. Transport means are the basic source of air pollution in urban areas and it's contribution is over 75% due to use of old vehicles.

The Ministry of Transport's statistics in 1994 indicated that more than 60% of cars are 12 years old and 26% of cars are more than 24 years old. As it is known, an old car produces pollutants from 10 to 20 times more than a new fabricated one. However, the quality of the fuel has an important role of increasing the air pollution. For example, the used diesel oil in Syria has a high percentage of sulfurs that exceeds several times the international standards.

There are other factors that assist the high level of pollution like, narrow streets, especially, in the old districts, which are difficult to be cleaned and ventilated. In addition, the decline of the green areas, the deterioration of the surrounding regions of cities, the change of land's use due to the expanding constructions and desertification, all these factors increase the environmental hazards.

Particulates:

The particulates are considered the most common air pollutants, mainly, in arid and semi - arid, industrial and crowded traffic areas. These particulates are consisted of a mixture of solid particles and fluid drops of various consistencies, sources and sizes.

The bad influence of the particulates depends on their sizes. Thus, the particulates with a diameter less than 2.5-micron cause a severe dangerous health effects because it penetrates the respiration system and reaches lung's alveolus. The particulates are, usually, the result of fossil fuel combustion, such as, soot and other particles of secondary sources, which result from chemical reactions of nitrate and sulfurs. These particulates are coated with poisoned mineral elements such as Lead, Cadmium and others. The particulates lead to many dangerous diseases of the respiratory system like Asthma, cough and bronchitis, consequently, pulmonary emphysema and cardiology failure.

The International World Health Organization's studies clarify that each casual increase of the less than 10 micron particulates concentration, which equals 50 microgram/m3, raise the deaths' percentage of heart and lung diseases from 2 to 8%. The recent studies confirm that the particulates contamination is one of the greatest problems in most developing countries, besides, it is responsible for 7 to 10% of children's deaths of pulmonary disease, in the less polluted cities, and 21% in the polluted ones with particulates.

What is the real situation in Syria?

The new measures refer to the high contamination of particulates, whether total or fine sizes, in most Syrian cities (look frame 3). The average of the total particulates concentration is between 213 to 430 microgram/m3 in Damascus and 300 to 600 microgram/m3 in Aleppo. According to WHO (World Health Organization) standard, of daily allowable level is 120 microgram/m3.

This condition is not, only, found in big cities but, also, in smaller and medium cities as well, such as, Homs, Tartus, Swaida and others. Never the less, it should be mentioned that the concentration of the total particulates have reached in some areas of old Damascus like, Madhat Basha street, leveles ranged between 870 and 1290 microgram/mژ3گ.

The high concentration of particulates which its diameter is less than 10 Micron and those of a diameter which is less than 3-micron are the worst pollutants because the human's respiratory immune system cannot resist it. Actually, these pollutants penetrate the respiratory system and reach into the depth of the lungs because their concentrations are 2 to 4 times higher than the permitted limit, which is 70 microgram/m3. On the other hand, the particulates with a diameter that is less than 2.5-micron, which affect the health very badly, have an extremely, high concentration which exceed the suggested limits many more times.

The most important reasons for these high concentrations are due to soil erosion, the decline of the plant cover in the surrounding areas of cities, besides, the transport's old vehicles, the different industries inside or around cities, roads' constructions and traffic.

Cement industry is another important factor, which assist the increase of particulates concentration (frame 4). The studies of the last few years indicated that these concentrations of dust cement factory area or the surrounding areas are much more higher than the permitted average and it affects health and other ecosystem's components badly, especially, soil and plants. The measures of 1999 in the surrounding areas of Tartus' Cement Factory cleared that the quantity of dust sediments on olive trees was about 5 to 17 times higher than in the other far areas from the factory. This high contamination, of course, ruined plenty of the surrounding olive trees, which became unproductive. The half diameter of the affected area by the Cement factory reaches about 5 kilometer.

The harmful influence did not, only, affect olive trees but all the other crops as well. Furthermore, it affected tourism and created many health problems. Already, the inhabitants of the surrounding villages, who live near the Cement factory, are complaining of pathological symptoms, especially, Asthma, beside pulmonary and other diseases.

Solid waste:

The information of 1995 pointed that the solid waste in the Syrian cities reached about 6000 ton/day, which mean 0.4 kg/person/day. In the year 2000, the solid waste of the whole regions of Syria reached 10.000 ton/day. (Frame 5).

The major part of the collected solid wastes from the Syrian cities, towns and villages (its national strategy for environment's capacity is 5000 ton/day) is left in open waste dumps which are located, in most cases, not much far from the residential areas. Consequently, a lots of problems came out, mainly:

1) Many tramps delve into solid waste to collect some elements, such as, organic ingredients that could be edible for poultry and animals' feeding, bread remainders, metallic and plastic objects. The searching starts in the trashcans before deporting the waste into the open dumps. Naturally, the tramps are exposed to many health problems, besides, more difficulties arise for collecting and deporting the garbage. Although tramping is legally prohibited, delving into the garbage became a common view in many cities. Actually, more than 10 thousand tramps exist in Damascus and its suburbs.

2) Solid waste contaminated the superficial and groundwater as a results of fermentation of the organic components.

3) The open dumps form a suitable climate for the growth of pathogenic microorganisms, flies, mosquitoes, reptilian insects and rodents, also, roaming animals like dogs and cats, beside the stinking smell. Fires in the open dumps present a real problem and, sometimes, it is difficult to control it. More often, most of the dumps burst into flames and produce smoke, which contaminates the surrounding environment. In addition to the offensive smell, the flying dust and the scattering trash, such as, paper and plastic bags, which spread into a broad area around the open dumps, cause an environmental contamination and undesirable views.

Worst of all, the medical disposals are still collected together with the solid waste in all Syrian cities, except Damascus, which started new efforts to collect medical disposals separately, excluding, some private hospitals that do not adhere to this rule. The quantities of the medical disposals in Syria reach about 3600 ton per year, added to that, the clinic's disposals and the specialized medical centers which include dangerous medical disposals, such as, tissues, human limbs, removed bodily parts, contaminated pads, sharp tools, syringes, chemical elements and others. It is, obviously, clear that the solid waste are very dangerous, especially, if some trashcans include medical disposals which might the tramps delve into it searching for glass and plastic objects. The resulting mess of the scattered trash contaminates soil and air, moreover, it causes the propagation of mosquitoes, flies, various insects and rodents which transmit the contamination into wider areas.

solid waste in Syria in 1995. (Ton/day)

Lead:

The Lead became, at present, one of the most important heavy elements, which contaminates the external environment and the work-field atmosphere. The transport vehicles, which use leaded fuel, are the main sources of contaminated air by lead and responsible for more than 90% of lead's pollution. In addition, the metal industries, especially, batteries' fabrication, assist to the increase of environmental pollution.

The Lead causes sever health problems. It combines with the enzymes and decreases the haem biosynthesis and causes the brain, kidney and sexual organs poisoning, besides, the hypertension and the cardiac disorder. Furthermore, it decreases the children's intelligence and affects their behaviors toward more aggressiveness, beside the lack of concentration and the less attention for their schoolwork.

The concentrations of lead in some areas of Damascus City were higher than the permitted limits (0.5 - 1 microgram/mژ3گ). After stopping the addition of lead into fuel, the average of concentration decreased in Damascus into the permitted standard, except, in some regions like, the irregular industrial areas that re-fabricate old batteries and have other metal industries, which exceed the permitted standard. In Aleppo City, the concentration of lead is still high in various areas (Frame 6). Therefore, certain procedures should be taken to decrease the high concentration of lead.

of Aleppo City (Microgram/mژ3گ)

Noise:

Years before, the Syrian cities were calm and quiet except from the voices of passing peddlers, sounds of some manual crafts and few crossing cars. These conditions changed completely. Now a day, many urban regions, even small villages have high levels of loud noises that exceed the permitted limits.

The level of external noises at the streets of Damascus reaches more than 90 Decibel, especially during traffic hours. The measures of year 1999 in Aleppo cleared that the levels of external noise at the residential areas reached 68 to 75 Decibels. Usually, the permitted limits at the residential areas should not exceed 55 Decibel during day hours and 45-Decibel at night in the commercial areas. As for the interior noise, whether inside residents or hospitals, the levels of noise were with an average of 10 to 26 Decibels higher than the permitted standard.

The big differences between noises' levels from one moment to another are very dangerous. These differences reach some times 28-30 Decibel because of the sudden bruit as a result of cars' horns, motorcycles, buses, Trucks and other vehicles of transportation. The measures pointed out that the levels of noise remain high until late hours at night.

It is known that the high levels of noise have bad health effects, such as, the exhaustion of the hearing sense, the retardation and incapability of the auditory sense, the contraction of the blood veins, the hypertension and the insomnia. These influences lower people's function, especially whose works demand more attention and accuracy. Children, students and sick people are sensitive to high levels of loud noise. Therefore, a standard measure of noise's levels was imposed for schools and hospitals, in which does not exceed the average of 45 Decibel.

Nature in the Cities:

The constructions of cities were and still associated with the complete destruction of nature and its characteristics of plants, animals and others. This means that a city's construction is a desertification act due to the absence of normal environment in it.

Plants continued to form an important role in the old cities and suburbs, which enabled chances for the residents of cities to relieve and relax from the pressure of the urban life. Besides, plants provide a cover, which insure the shadow and help to absorb dust, also, lower the gaseous contamination and loud noise. Therefore, the institutions of Municipalities in the world paid a special attention to beautify cities and expand the planting of trees and flowers in the streets and roads, also, expanding the establishments of public parks, gardens and increasing the green areas inside cities. The enlargement of green cover is considered a complementary part of the architectural designs of cities. (Frame 7)

The environment of cities, at present, suffers from the decline of green areas, gardens and public parks. In Damascus, for example, Jasmine and roses formed a part of its domestic waste. Now, the green areas of public parks became less than one square meter for each inhabitant.

Now a day, the 'Ghootah' (a famous fertile oasis in Damascus) deteriorated and no more roses or flowers are seen in its public gardens. On the contrary, more illegal disordered constructions expanded on the expense of some public parks, like the 86 region in Mazeh Mountain. Actually, Highways and roadsides became the picnic areas for most people during the holidays and weekends.

parks in cities

Housing and Urbanism:

The location of industry in the cities followed by the active commercial, social and scientific fields, which created chances for work, caused the increase of immigration from villages into cities with high levels.

Due to the immigrating numbers of people and the natural growth of population in cities, urban regions, especially towns, started to expand with disorder outside the organized regions swallowing valuable plantations and entire villages.

Therefore, many infringement districts, besides being, heavily, crowded, they were established with primitive services, which caused many diseases due to the unhealthy environment (Frame 8). These hazardous settlements have three mutual distinctions, which are:

1 - The poor structural foundations and services or missing it at all, including drinking water, drainage system and proper methods of solid waste disposal.

2 - People live in crowded places, which lack the provisions of firmness and space, moreover, the non-existence of gardens, parks or green areas. The improper conditions of crowded residents caused a social defect, as well as, social and health problems.

3 - Most of these settlements are build in unsuitable areas for residing, such as, slopes and bottom of mountains which are exposed to soil collapses, or nearby industrial contamination and others. The residents, therefore, suffer several troubles, like, particulates contamination, floods due to the superficial water flowage and various diseases.

The Ministry of Housing and Services declared that due to the lack of serious procedures since the beginning of these hazardous settlements' installations, many issues arise, mainly:

a) The inability to apply and execute planning designs for these regions.

b) The continuous surmounts of laws and regulations.

c) The stealing of water from the neighborhood nets which caused a shortage of water.

d) The increase of groundwater' contamination due to the lack of sewage system.

e) The decline of electric power because of the illegal draws from the surrounding areas.

f) Deforming the architectural look of a city.

Frame No. 8 The assemblage of disordered

Settlements in Damascus City

Moreover, the Ministry of Education explains that the pedagogical situation in these disordered settlements is improper because most of the schools are leased residences, which lack the provisions and the characteristics of regular schools. To understand the deteriorated pedagogical conditions of these settlements, it is better to present what the Directory of Education in Damascus clarified about Tabaleh and Dwailah positions:

The pedagogical position in Tabaleh and Dwailah:

The area of Tabaleh and Dwailah extend from the west of Damascus airport-road until the boundaries of Melaiha town-east. Its residents are of low income people, workers and many employers. It has 17 primary school for 7260 students. The average number of students per class is 60 students. Accordingly, the Directory of Education applied the system of the half-day study in order to contain all the students.

The leased schools, which are residential houses, are narrow buildings and lack the essential provisions of regular schools, such as, light and ventilation. In addition, its courtyards are very narrow and not enough for the students to be aligned, the classrooms are tight, stuffed with students and benches, which assist the fast spread of diseases among the students. Besides, bathrooms are next to the classes. In addition, there are no gardens or recreation areas, therefore, activities and sport are canceled completely.

In this area, there are no Elementary, Secondary, Technical or training schools. Thus, hundreds of students are obliged to go into other far regions risking the danger of accidents. Beside the fatigue of reaching schools, the students are exposed to hard cold as well.

Land Resources:

The total area of Syria is 185180 km2, which is distributed as follows:

A) The arable lands form 5981 million Hectares.

B) The non-arable lands form 3370 million Hectares.

C) Meadow and pastures form 8270 million Hectares.

D) Forests and woodlands form 537 thousand Hectares.

The reports of the National Strategy of Environment in the year 2000 point out that more than 50% of the arable lands (3.2 million/Hectare) suffer from the negative influences of erosion, salinity and desertification. In fact, In spite of the legislations, which were established to protect the arable lands, many areas are non-arable anymore due to the urban expansion (disordered settlements), industry or domestic and industrial waste. As a result, the production of some crops declined, besides, pastures and animal wealth. Furthermore, forests lost their environmental and entertainment resources. The National Strategy of Environment estimated the resulting loss about 14500 millions SP in 1997 and 17700 millions SP in 2005, in the case that no appropriate procedures would be taken to protect the land resources.

The main important matters of land resources are the following:

1) The degredation of the natural pastures:

The Syrian semi-desert, which includes land that its yearly average of rain is less than 200mm, form about 55% of the total area of Syria (10.2 millions hectare). Its population is about 1.5 million inhabitants in which 250 thousands of them are farmers, 750 thousands are half Bedouins and 500 thousands are wandering nomads.

The Syrian semi-desert was known over the years as one of the best and richest semi-deserts due to its natural grassland. It was a resource of biodiversities, thus, many civilizations, which had an important political, cultural and civilized role in the history, were established and flourished in it. Nevertheless, Its influences affected the history of east Mediterranean Sea, such as, Palmyra, Al Salhia, Al Rasafa, eastern and western Heer Palace, Iben Wardan and others.

These cultural examples, which refer to the ability of the old gathering settlements to continue living over a long period of time, mean that the inhabitants, logically, dealt with the surrounding environment and limited resources to prevent its degredation and consumption. As a matter of fact, all possible capabilities were used to administrate the available resources of pastures, land and water, like collecting, deporting and storing water in reservoirs or special drilled wells in the rocks to protect water from evaporation and leakage. In addition, there were legislations that organize such matters, like water distribution, pasturage and logging. Accordingly, these former civilizations were able to preserve the plant cover of the land and secure the soil from degredation, beside prevailing oasis planted with Palm, olive trees and grapevines.

This flourishing view of the semi desert started to change since the middle of the Twentieth Century because of the following:

- Overgrazing: The increase demand for animal production led to the increase of the number sheep, which increased from 206 million sheep in 1950 to 15.6 million sheep in 1998. This increase caused the phenomenon of the overgrazing, which destroyed plenty of the pasture's plants, especially, the palatable ones.

- The ploughing: The planted areas increased on the expense of the natural pastures, especially, in the regions that the average of rain is, less than 200-250 mm/year. The planted non-irrigated areas increased in the Syrian desert from 36 thousand hectares in 1982 into 218 thousand hectares in 1985 and reached 552 thousand hectares in 1990. In spite of the unsuitability of these areas for that sort of investment, this increase continues on. However, ploughing is considered one of the main reasons for the desertefication of the Syrian semi-desert.

- Transport vehicles: Big trucks are still used to carry sheep from one place to another seeking grassland, as well as, tankers that transport water. These vehicles degrade the plant cover and the soil because most of the desert regions are flat with wide and slightly deep valleys, which tempt the drivers not to comply with one specific road. Therefore, the big trucks broadened the width of roads into hundreds of meters, consequently, they formed an environment for desertefication. In fact, each 10-km drive with a big truck in the desert causes the deterioration of the plant cover and soil of about one Hectare. The studies point out that due to the transport vehicles between Damascus and Baghdad, the desertified areas on the roadside reached 400 thousand hectares. However, the average distance for a truck to transport water for the herds of sheep is about 38 km per day. Transport vehicles, indirectly, helped the increase of logging, through its capacities to reach for far areas from Bedouins' places of settle and, also, its facility to carry more logged plants.

- The logging: Many bush trees disappeared from the desert because of logging, which increased the deterioration of the plant cover, soil erosion and water cliffs. Moreover, Bedouins, in most cases, cut the plants with the high nutritious value, which caused the decline the productivity of pastures. Woodcutting destroyed the Pistacia forests, which area in the mountain' regions of the semi-desert declined from 300 thousands hectares to some hundreds only. The same happened to the fig trees, which are, rarely, found in some valleys of the mountains' regions and the tamarisk which is found on saline soil. Almost, 400 millions bush trees are, yearly, cut from the Syrian desert. The estimations, also, point out that each kettle of tee needs the burning of 5 bush trees, meaning that 50 million bush trees are burned per year in order to prepare the daily kettle of tea. Nevertheless, the burned bush trees for warming, cooking, backing bread and boiling milk are estimated 10 times more. Because of logging, more than 10 to 12 thousands hectares of the flooded lands are ruined.

All the previous practices are reflected in the degredation of the plant cover, the gradual soil erosion, especially, slopes and the vanish of the organic elements from superficial layers of soil, which have an important role of improving the structure of soil and increasing its ability for the rain penetration.

The degredation of the plant cover and soil caused the increase of the heavy floods, especially, in the mountains of the desert. It is noticed that in spite of the few quantities of rain, it is, always, accompanied with heavy floods, to the extent that the roads become obstructed. Moreover, the rain of the Mediterranean climate is strong and intensified in certain days and months of the year, which facilitate the soil erosion, mainly, in the lands, which lost its plant cover.

The map of World Food Organization, of year 1980, shows that the escarpment of soil in the Syrian desert under the effects of the overgazing, ploughing, logging and others are estimated from 10 to 50 tons/hec/year. This equals the scarp of soil layer from 0.1 to 0.5 cm/year. These numbers are astonishing and require necessary and strict procedures to stop this consume of the environmental resources.

2) Forest and woodland degredation:

It is difficult to consider the present plant cover as the one, which equilibrate with the surrounding atmosphere. In fact, the present coat is a retreat of the natural green coverage affected by the unwise humans' investment, through cutting, burning, planting and others.

Embeger mentions that huge areas of east Mediterranean countries are covered, at present, by wild plants, which are unsuitable for the actual climate and much less proper than its capabilities. On the other hand, Walter clarifies that the high regions of east Mediterranean Sea were, completely, covered with forests. Unfortunately, most of these regions lost its natural plant cover to the extent that it might be impossible, sometimes, to restore it because of the soil escarpment and the transformation of these regions into desertified and non-arable lands.

A map of Syria, which was sketched in 1666, clarifies that the interior parts of Syria were dense forests. Actually, forests covered the neighboring regions of Damascus to the west, also, the regions between Aleppo, Kalamoon and highlands till the north of Palmyra.

According to various studies, the forest area covered 20 - 30% of the total area of Syria, whereas at present, it is not more than 2.4%. It is difficult to give an exact number of the present area of forests and woods in Syria, the available estimation range from 461 to 537 thousand hectares. The World Resources of 1999 estimated the area of forests in Syria about 484 thousand hectares, in which the natural forests form about 232 to 245 thousand hectares of it.

World Resources pointed out that the decline of forests due to the natural fires, the undisciplined logging and pasteurizing reached 3.2% from the year 1980 to the year 1990 and 5% from the year 1990 to the year 1995.

The former and present deterioration of forests causes the change of local environment toward more dryness of microclimate levels, in addition, the degredation and erosion of soil. The forests' deterioration is considered responsible for the environmental collapse in the same regions that the forests were removed from, besides, the inclination toward dryness and the emergence of flowing floods. This deterioration appears clearly in the littoral and interior regions.

The superficial flow of rain, especially, on the slopes, and the floods' emerge are accompanied by a noticeable decrease of supplying the ground water and the fountains' exuberance. As a result, the lack of supply affected, negatively, the water storage and, of course, its association with the disturbance of social and economical life of inhabitants.

3) The soil salinity:

The improper investment and administration of irrigated lands caused and still causes the salinity of some lands. The salinity appears, especially, in the soil that has a bad ability to drain water or due to the irrigation with salty water. The statistics point out that 532 thousand hectares (40% of irrigated lands) are affected by salinity. Moreover, 60 thousand hectares of fertile land in Al Furat and Al Khaboor basins are out of investment because of its salinity. Furthermore, 100 thousand hectares are partially saline and its productivity of crops declined into less than half. While the productivity of 90 thousand hectares declined by 25%, another 100 thousand hectares

Declined by 15%. Therefore, Syria is, yearly, loosing 4 to 5 thousand hectares of fertile and arable lands because of salinity.

4) The biodiversity:

The biodiversity means the following:

- The diversity of the natural ecosystems, such as, forests, meadows, swamps and others of land and water ecosystems.

- The diversity of Plant and Animals which form the ecosystems.

- Races, Ecotypes and Varieties, which are related to species of a plant or animal, in addition to the old landraces of agricultural crops.

The biodiversity, which is associated with genetic diversity, composes a huge valuable wealth. In addition to its role of ecosystem's settle and balance it offers for agriculture, industry and medicine the nutritive elements, drugs, new medicine and the primary elements for industry. The biodiversity, races, varieties and its genes are considered necessary for protecting and improving the agricultural production, the forests and the fishing grounds to face the unsuitable changes that might occur to the environment.

The present situation of 'biodiversity in Syria is considered very critical. It is clarified by the collapse or the complete vanish of some woodland's ecosystems, also, the decline of the plant's extended areas or its complete disappearance, besides, the rare found of some wild animals or their extinction. The main reason for this critical condition is the degredation of the natural ecosystems, which happened before and, presently, continues but faster than before. Of course, this fast degredation is due to the oppressive and unbalanced investment of the renewed natural ecosystem's resources. For example, cutting forests to be transformed for planting, the overgrazing in the forests and the desert, the cultivation of the desert's lands, besides, the intensive hunting of wild animals and others. Hereunder, some examples of the deteriorated ecosystems which are threatened to disappear:

a) The forests of Pistacia atlantica at the desert's mountains and Abdul Aziz mountain. The studies point out that it, formerly, covered an areas of 300 thousand hectares, now a day, its area became less than hundreds of hectares.

b) The forests of Juniperus excelsa in Al Kalamoon's mountains of Syria which, almost, vanished except some scattered trees.

c) The forests of Abies cilicica and the Cedrus libani forests, which are of the most beautiful forests in the world, unfortunately, in the late years, it turned to be reserve ecological areas.

d) The forests of Pinus brutia and Quercus calliprions in the coastal mountains.

e) The historical information indicate that Oak, Acer microphyllum, Ulmus minor, Rhmnus palaestina, Prinus microcarpus, Almond, Azarole and others formed expanded forests in the mountains of eastern Lebanon series, also, were obtained at the mountains of Al Kalamoon. At present, they are all forgotten.

So much little is known about the types of plants and the rare species of animals which are threatened to disappear, or, about the species which, completely, vanished because of the microclimate's collapse. The information refers to a number of wild animals that lived in the east of the Mediterranean, which extinct due to the deterioration of its natural ecology and the oppressive hunting, such as, the Lion, who was known until the 12th Century, besides, Zebra and Antelope. As for the Deer, this animal is threatened to vanish, which might have, already, disappeared in its natural ecology. The deer (the traditional quarry) is exposed to eradication in front of our eyes, with the use of the best new methods of hunting. The studies about the old civilizations that were established at the Furat's basin refer to the big numbers of animals at those times, which represented an important resource of nutrition for the inhabitants, especially, the Deer, which bones formed more than 80% of the total discovered bones. Moreover, bone parts of extinct Zebra, goats, pigs and wild bulls were found in that region.

Although there are no exact statistics about the extinct or threatened birds, it is certain that a big number of birds had, severely, declined. Recently, no more partridges, or bustards nor other birds' coveys are seen. As a matter of fact, fowls were available with big numbers since a period not so far from now.

5) The natural reserves

The right administration of the biodiversity is more than an aesthetic desire, but it is a life necessity and a moral commitment toward our environment and other existing beings who share this life with us, as well as, a moral commitment toward the present and succeeding generations. The best place to preserve the biodiversity on earth is the vital ecotypes in which the existing beings live, especially, the natural reserves and national parks.

The natural reserves are big areas that include natural ecosystems, which are preserved from ruining and, at its limits, any human activity, which might cause its deterioration, is stopped. The reserves should occupy large and variant areas, which represent all the natural regions of the country. Inside the reserves, all the ecosystem's components are provided with full protection, especially, the animals and plants that are threatened with extinction.

The Reserves differ according to their ecosystems and purposes. Some regions might be, completely, protected, or only some components of the ecosystems, like protecting species of the threatened animals from extinction, or protecting a certain plant for its aesthetic or historical value, also, protecting some topographical forms and others. As the reserve regions provide the mechanism of preserving the biodiversity, most countries established reserve regions (frame 9). Thus, the number of reserves increased in the world from 1478 reserves in year 1980 to 9793 reserves in year 1994. However, the reserved areas in the world increased from 164 million hectares in 1970 to 652 million hectares in 1990. Nevertheless, the reserves covered in year 1994 the area of 7.1% of the ground.

In Syria, there is a reserve, which exist in the 'Island of Thawra' at Furat's river with an area of less than 590 hectares, beside the Al Shouh and Pine reserve at the littoral mountains. Also, there are fenced areas of the Ministry of Agriculture that spread in various regions of the semi-desert. In spite of the mentioned reserves, according to the criterions of the World Union to Preserve Nature, the reserves do not exist in Syria.

6) The water resources:

The estimated quantity of superficial and groundwater in Syria is 10 Milliards Quebec meter per year, except the share of Syria from the supply of Dijlah and Furate's rivers. Presently, the superficial and the groundwater are considered, almost, consumed in most regions. A watery impotence is expected in many regions of the country because of the increasing demand for water.

Some influences of water's decline are noticed through the diminishing of groundwater's level, the increase of salinity and the hard suffer of some regions, mainly, at Barada's baisn and Al A'awaj river, of severe shortage of drinking water, especially, in the last years. The excessive consumption of groundwater increased because of the illegal and disordered drillings of wells, without taking into consideration the balance of the consummated water with the possibility of renewing it by the falling rains. Therefore, the groundwater's level declined and in some cases dried completely, as what happened in Al Salamiah during the 50ies of this century. Moreover, the excessive consumption of groundwater continues, at present, in Damascu's baisn, Al Jazeera and Aleppo, which threatens the ecological, agricultural and social balance.

However, the World sources of 1999 pointed out that in 1996 the safe drinking water covered about 92% of the urban regions and 78% of the rural regions.

7) Drainage System:

Drainage systems are fully applied in all main cities of Syria. More often, sewage water are thrown into the nearby watercourses and valleys, or used for irrigating crops. While big villages have limited sewerage system, which sewage are released in valleys, the small villages lack sewage system and deliver waste into what is called - the technical room.

Seawater and rivers of the coast are considered the main places to get rid of sewage, except Damascus City, Homs and Al Salamiah, which have stations for sewage treatment. Thus, for example, while Latakia and Tartous turn sewage into the sea, most cities of the middle region turn sewage into Al Assi River. Accordingly, rivers and seashore became contaminated.

The sources of the Ministry of Irrigation indicated that the water of Al Assi River became of bad standard, especially, after flowing out of Homs till its end. The same sources refer to the unsatisfactory standard of seashore water for tourism, starting from north Latakia till Amreet in south of Tartous City.

The National Strategy of Environment of year 2000 clarified that the lack of sewage's treatment, the water contamination, the shortage of drainage systems and the decrease of vital provisions in lakes and rivers cause bad damages. These damages are estimated of 5000 million SP in 1997 and about 8800 million SP in year 2005, in addition to more than 8000 million SP, which are the costs of water resources and the decline of ground water storage. The National Strategy of Environment, also, revealed that the lack of sewage's treatment in most regions of the country caused the contamination of the superficial water and bad influences on health. Actually, the number of ill cases, which were transmitted by water, reached hundreds of thousands that were reported in 1996. In addition, there is the problem of contaminating some agricultural crops, which are irrigated by sewage water.

Conclusion:

In most cases, the economical progress did not associate with preparing policies and organizations to plan a complete treatment of the environmental collapse and the methods of protecting it. This lack of interest encouraged the improper investment and preservation of the environmental resources, besides, exposing the prospects of the social and economical growth for danger. As a matter of fact, the practical experiences in the entire world clears that the neglect of taking serious acts now, will, only, lead into the increase of costs and complicate the procedures of treatments which might be taken later on. Obviously, the problems which affect the human health or that which result an economical loss should have the priority of treatment.

Every strategy, in fact, which is directed to reinforce the sustainable development, should depend on three main issues, which are as follows:

1 - Fortifying the environmental organizations and public participation:

The administration of environmental affairs is rather a new field in Syria, therefore, the establishment of the organizational capacities in the field of environmental policies represent an utmost priority. This, of course, demands the improvement of the technical and administrative capacities and the fortification of the observing systems and the execution of the environmental standards. Also, It demands the wide publicizing of the danger, which environment might be exposed to. Besides, the participation of the public to specify the priorities and make decisions, as well as, the increase of enlightenment about the environmental issues, plus, the urge of public work and the raise of the citizens' capacity to participate in preserving the environment.

2 - Improving the administration of the natural resources:

The issues of the environmental degredation, such as, air pollution, water decline, desertefication of pastures, the salinity of arable lands and others imply an essential restrain for the economical growth in the future. Also, energy, in spite of its availability now, will be tight in case the present excessive consumption continues. Thus, the tendency of growth should be redirected away from the excessive investment of the natural resources base, by meliorating the administration system, increasing the qualifications and reducing the dissipation.

3 -Terminating the arising problems of pollution:

The urban and industrial contamination, also, the lack of sufficient and safe drainage systems represent an increasing threat for the public health. The strategy of the environment has to treat the effects of contamination on all levels, like:

- Improving the water standard.

- Meliorating the drainage and sewerage systems.

- Rectifying the industrial functions of high level contamination.

- Decreasing the pollution of transport.

- Clearing fuel from lead and the fuel of high sulfur.

- Using emanating regulators for transport vehicles,

- Hurrying to apply natural gas for transport's vehicles and others.
