Growth Of Silvicultural Trees Planted As Shelterbelts And Windbreaks In Wadi Hadhramaut – Republic Of Yemen, Ahmed Salem Bataher
Hadhramout University Journal of Natural & Applied Sciences
The study had been conducted in Wadi Hadhramaut. Regular tree samples from windbreaks and shelterbelts had been collected for at least 3% sample size of each site while measurements of each tree were applied. High percentages of trees growth for height and stem diameter occurred in summer while crown width in spring. Evidence of measured trees in agricultural areas showed low and high figures of standard deviations ( ±0.538 - ±2.211m , ±0.539 -±3.289 m and ±1.652 - ±6.775 cm ) for height , crown width and stem diameter respectively, while the coefficient variation range of these characters were 7.06 …

Replanting Of Aloe Inermis And Aloe Eremophila And Their Bitter Sap Exudation Quantity And Time Of Extraction, Ahmed Salem Bataher
Hadhramout University Journal of Natural & Applied Sciences
Aloe inermis and Aloe eremophila are a drought resistance species habituating plateaus and high mountains. These two plants can survive outside their natural habitation and they can be irrigated under basin or drip irrigation systems. The plant sap can be collected locally at noon by cutting leaves from the bases beyond 2.5 cm of the stem. The mean dry sap production is ranged between 0.37 – 0.47 gm/Leaf for the species Aloe inermis and Aloe eremophila respectively. Statistical analysis of the dry sap production revealed a significant difference between means of the two species at 5% of level which the …

Jerash for Research and Studies Journal مجلة جرش للبحوث والدراسات
Water samples were collected monthly during 1999, from four sites, of different habitats. The study revealed the existence of a total of 120 phytoplankton species, composed of 76 Bacillarophyte, 37 Dinoflagellate, 3 Cyanophyte and 4 Chliorophyte species. Moreover, the study also revealed considerable physio - chemical variations in their water, as well as considerable variations in chlorophyll a. The physio - chemical variations of water, in the four stations most likely is responsible for the variations of the phytoplanktonic species found in them and their population densities.

Integrated Water Resources Management: A Tool For Sustainable Development, Helene Hanna Jazi Dr.
Future Engineering Journal
The recent trends show a decrease in water supply coupled with water losses due to inefficient management and pollution. The phenomenon is called water scarcity and he’s affecting people’s livelihoods around the world. Many approaches have been investigated through international water conferences and forums to develop tools for sustainable water management. IWRM (Integrated Water Resources Management) is one of the most widely adopted tools focusing on a holistic and participatory approach, involving users, planners and policy makers at all levels. In this study, the key concepts of IWRM and its potential in improving the water sector and inducing sustainable …
