Abstract Water is a significant primary resource on the earth's surface. Fresh water is essential for a human being and for the stability and sustainable development of any nation. Many regions in the interior of Syria have an insufficient water balance. This has caused severe shortages of freshwater as a result of climate change. Syria's main source of fresh water, rivers and groundwater, suffers from low levels due to the lack of rainfall amounts. The war in Syria exacerbated water stress, in particular the effects of the war on water sources such as the Euphrates River and the ‘Feijah’ source that feeds the capital Damascus. All of this has prompted us to seek other non-traditional sources such as atmospheric water, which is a renewable and relatively clean source. This paper is considered to be the first of its kind in Syria. Experimental results from semi-arid and arid regions have shown good potential for harvesting dew and fog water as a supplementary and complementary source to the existing freshwater supply.

The chemistry and macrofauna of a temporary rainpool on soft substrata near Kalgoorlie, Western Australia, are described. The ionic composition of the water was dominated by sodium and chloride and salinity was relatively high (5324 ppm). The fauna was depauperate and many faunal groups typical of fresh water were not recorded. Several groups often found in temporary localities were also not recorded, including chironomids. Insects (Hemiptera, Coleoptera, Diptera) dominated the fauna. Also present was a species of frog (larvae) and various crustaceans.

In terms of geology, most areas in south of the Gunungkidul District in Central Java consist of the Wonosari formation limestone. The land is generally very dry and source of raw water is also difficult to reach. Findings on the existence of underground river in caves, however, indicate the potential amount of water within the area, especially in the eastern part of the Gunungkidul District. Although limited information available, some fishermen have discovered that Seropan cave contains fresh water source. This cave is situated at 65 m below the cliff. Initial exploration, which done using a multichannel resistivity method, confirmed the availability of freshwater in the cave and underground river. The isopach of cave depth is found in ranges of 80 200 m below the ground surface. The water of Seropan cave can be utilized by implementing pipeline or by drilling at the suggested point based on the interpretation results, i.e. 110o2223.6388 EL 8o42.874 SL.

Ponds are an important fresh water critical ecosystem for plants and animals providing goods and services including food, fodder, fish, irrigation, hydrological cycle, shelter, medicine, culture, aesthetic and recreation. Ponds cover less than 2 percent of worlds land surface. Ponds are important source of fresh water for human use. These are threatened by urbanization, industrialization, over exploitation, fragmentation, habitat destruction, pollution, illegal capturing of land and climate changes. These above factors have been destroying ponds very rapidly putting them in danger of extinction of a great number of local biodiversity. It is necessary to formulate a correct conservation strategy for pond restoration in order to meet the growing needs of fresh water by increasing the human population. Some measures have been compiled and proposed in the present review.

Ptychobothridean genera like Senga and Circumoncobothrium are the common parasites of fresh water fishes. The genotypic study of these parasites was taken by RAPD. The RAPD profile of these two parasites were not similar to each other as depicted by the band pattern in picture. These results suggest the presence of inter-specific polymorphism among cestode parasites of two different genera for RAPD analysis. The present study demonstrated that genetic differentiation of cestode parasites could be accomplished on the basis of genomic variation with polymorphic band pattern using RAPD. All the detected bands (PCR product) were polymorphic and band size ranged from 500-5000 bp in length. The RAPD of profiles using GBO-31, GBO-32, GBO-33, GBO-34, GBO-35 and GBO-36. Primers were able to characterize inter-specific polymorphism among the two genus ( Senga and Circumoncobothrium ). Genetic analysis suggests that Senga and Circumoncobothrium show genetic diversity with respect to RAPD patterns using all the six primers used for the present study. The genetic distance between the analyzed genuses ranged from 0.14 to 0.80. The differentiation of the two parasites on the basis of genetic markers could greatly facilitate study on the biology of these parasites.
