The crisis in Syria heavily impacted public infrastructure as well as the provision of
basic services. This strongly affected the population in all Syrian governorates since the
beginning of the crisis seven years ago. The water sector is considere
d one of the most
affected. Hostilities led to damages in the networks and ensuing water cuts. In addition,
main pumping stations, boreholes and sanitation networks ceased to function. This
research aims at identifying the locations and extent of damages in the water networks in
Homs governorate based on the percentage of water and sanitation networks as well as
solid waste management services compared to the pre-conflict situation. The research
depends on utilizing the Geographic Information Systems (GIS) based on descriptive data.
The information used comprises primary data collected in the field using structured
questionnaires filled by the local population as well as secondary data produced by
humanitarian organizations, SARC and governmental institutions. The results show
decreased the coverage of water and sanitation networks in Homs Governorate notably
outside the county centers while it is almost non-existent in the urban areas. The latter
include the southern and eastern counties Al Qariateen, Sadd, Mheen, Al furqulus, Al
Ruqama and Hisia. Furthermore, more than half of the population living in the eastern
urban areas rely on water trucking. The discontinuity of municipal services and
malfunction of solid waste removal trucks resulted in the accumulation of waste in many
areas. Therefore, the state of solid waste management is evaluated to be mostly “bad”,
while the reminder only reaches “medium” category, which means, the municipalities do
not collect the waste, or collect and dump inside the city .This situation strongly increases
the risk of an outbreak of infectious diseases.
The biological role of chitosan which was prepared by chemical method from
shrimp waste Penaeus semisulcatus and the outer skeleton for marine crab Portunus
pelagicus in some industrial and agricultural applications were studied. The
concentration
of prepared chitosan was 1% (w/v) at pH (4 and 8) for 12 hours in
precipitation and chelating heavy metals (Lead, Zinc, Iron, Cupper and Cadmium)
from of sewage water. Concentration of elements was measured by Flame Atomic
Absorption Spectrophotometer ) FAAS). The results of the study indicated that the
concentration of the water elements was high before treated with chitosan. The
results showed a significant (p<0.05) decrease in element concentration percentage
after treated with crab chitosan. In contrast, shrimp chitosan displayed a minimum
effect on decreasing the amount of heavy metals. Moreover, the results showed that
the higher percentage for mineral adsorption was at pH (4 as compared with 8).
The results confirmed the possibility of using chitosan in chelate and precipitate the
mineral ions from polluted water.

An experiment was conducted for two seasons 2015 -2016, to study the effect
of treated waste water (TWW) on some fodder crops productivity at Salamieh
Research Center (GCSAR), on triticale and sesbania crops within crop rotation. This
experiment w
as conducted with collaboration between (ACSAD) and (GCSAR).
The experimental design was split plot design with three replicates, using drip
irrigation (DI) and surface irrigation (SI) systems with two treatments namely fresh
water (FW) and (TWW). Soil and water were analyzed before cultivation.
Half quarterly water samples were collected during the period between March 2015
and February 2016 of four different stations from Banias city water that is subject to the
effect of sewage and estuaries. The concentrations of nutrients (H3SiO4
-,
PO4
-3, NO3
-, NO2
-
, NH4
+ ) and the concentrations of chlorophyll a were determined to find out how affected
by the temporal and spatial variability. The highest concentrations of phosphate and
ammonia ions were observed at station St3 (close to the sewage), while the highest
concentrations of nitrate ions were registered at the stations St1 and St2 (estuaries). The
results showed high values of chlorophyll a in April (due to spring bloom of
phytoplankton) and October (autumn bloom). The ions ratio ΣN/P revealed that
phosphorus ions are limiting factor of the phytoplankton growth at St1 and St2, and that
nitrogen ions are limiting factor of growth at the stations St3 and St4. The ratio Si/ΣN
revealed that silicate ions are limiting factor of the growth of diatoms in all the stations.
This research aims to shed a light on the current state of the
Syrian water resource through studying the present resources
and analyzing the demand on them and their availability
during the period (1992-2012). This study focues at deriving
the f
uture forecast on the development of the demand on these
resources in order to better conceptualize their current state.
This in turn will lead to concluding a set of results and
recommendations that could contribute to improve the state of
the water resource in the sense of achieving sustainability and
prohibiting its depletion through the efficient and planned
usage.

This study was carried out during 2013 – 2015 and aimed to assess the effects of
applying dry sewage sludge on dry biomass production and wood volume of Eucalyptus
camaldulensis plantation established on sandy soil in Fedio plantation-Lattakia at A
pril -
2013.
Four experimental treatments were compared at age 22 months: SS1 (sewage sludge
3 kg/tree), SS2 (sewage sludge 6 kg/tree), MF (mineral fertilizer), and C (no fertilizer
applications). Aboveground dry biomass production and wood volume in the SS1
treatment were about 107.60 t/ ha and 121.13 m3/harespectively, MF treatment (87.52 t/ha,
96.98 m3/ha) and SS2 treatment (91.12 t/ha, 103.42 m3/ha)and higher than in the control
treatment (43.89 t/ha, 51.32 m3/ha ).
Generally, sewage sludge is dumped into sanitary landfills, even
though its use in forest stands as a fertilizer and soil conditioner
might be an interesting option. However, sewage sludge must be
applied with care to avoid soil and water pollutio
n. The aim of this
study was to assess the effects of applying dry sewage sludge on
wet biomass production and wood volume of short rotation

The study was conducted to determine the efficiency of the aerobic treatment of primary sludge resulting from sewage sedimentation and to determine the optimum residence time by measuring the indicators of total solids, chemical oxygen demand, organic content and dewatering ability of the sludge.
