IALC Selected Impacts

Each completed IALC project has produced many outcomes that include articles in journals, books, DVDs and CD-ROMs, M.S. theses, Ph.D. dissertations, presentations, and Websites.

Also, some of the projects have identified impacts. Several examples are shown below.

Project No: 06D-05

Title: Runoff, Flood, and Non-sewage Wastewater for Native Tree Propagation

Two new projects continuing this work have been funded. One will be between the Abu Rabia farm and the nearby Hura village addressing hilltop erosion and the dearth of fodder for sheep and goats and one at the Moshav farming village of Beer Tuvia studying the question of suitable arboreal pasturage materials for dairy cattle. Also, animals will be introduced to the sites that were planted during the project in the spring of 2010 and they will be monitored to determine the tree-to-animal ratio.

Project No: 06R-02

Title: Anaerobic Sewage Treatment for Sustainable Water Reclamation in Jordan

This project explores the use of an anaerobic treatment system known as the upflow anaerobic sludge bed (UASB) reactor as part of the overall sewage treatment strategy in Jordan. The advantage of anaerobic pre-treatment is to save energy and reduce excess biosolids production. Jordanian sewage has a high strength due to scarce water resources and in the highly populated plateau the sewage is colder than in neighboring Middle Eastern countries. Therefore the study explores adaptations of the UASB technology to imrove its performance with higher strength sewage and at lower temperatures. The results of the project indicate that by using an anaerobic pretreatment system, potentially 51 to 62% COD can be removed without any aeration indicating approximately 50% savings in aeration costs (and energy consumption). Likewise it is estimated that the anaerobic pretreatment system can decrease excess biosolids production by 40%.

Project: Funded under the IALC-USAID Project

Title: Wadi Musa

IALC project titled, Assessing the Capacity of Jordanian Nurseries to Supply Native Plant Species. This was a joint IALC-BRDC project conducted during 2005 in Wadi Musa, near Petra in Southern Jordan. It successfully showcased the use of treated effluent for animal fodder and growing cash crop flowers. The long-term impacts are that alfalfa is now being grown and opportunities for other non-food cash crops continue to develop. The use of treated wastewater and biosolids are being considered for use in other areas of Jordan.
