The irrigated area in the Aral Sea basin totals about 7. 5 million hectare. Part of the water supplied to this area is consumed by the irrigated crop; the remainder of the supplied water drains to the groundwater basin, to downstream depressions, or back to the rivers. During its use, however, this drained part of the water accumulates salts and chemicals. The disposal of this polluted water causes a variety of (environmental) problems. If the percentage consumed water of the total water supply to an irrigated area (the so-called overall consumed ratio) can be increased, less water needs to be drained. This alleviates part of the related (environmental) problems. Further, if the overall consumed ratio for the above 7. 5 million hectare is improved, less water needs to be diverted from the rivers. Hence, more water can flow towards the Aral Sea. As mentioned above, part of the non-consumed irrigation water drains to the groundwater basin. Commonly, the natural discharge capacity of this basin is insufficient to handle this imported water. As a result, the groundwater table rises towards the land surface causing waterlogging. In (semi-)arid zones this waterlogging triggers a soil salinity problem resulting to a significant reduction in crop yields. The artificial increase of the discharge capacity, and lowering of the groundwater table, solves the soil salinity problem.

This unique volume presents up-to-date information and the latest research findings on unconventional water resources in Egypt and their connections to agriculture. It investigates how to cope with the severe shortage of water and how to improve the irrigation system’s efficiency. The main aspects addressed include: · History of drainage and drainage projects in Egypt · Towards the integration of irrigation and drainage water · Assessment of drainage systems and environmental impact assessment of irrigation projects · Maximizing the reuse of agricultural drainage water and agricultural waste to improve irrigation efficiency · Developing alternative water resources, such as desalination, for greenhouses · Drainage water quality assessment, microbial hazards and improvement of green and cost-effective technologies for treatment of agricultural drainage water and wastewater for reuse in irrigation · Towards the sustainable reuse of water resources in Egypt · Options for securing water resources in Egypt, and challenges and opportunities for policy planners This book and the companion volume Conventional Water Resources and Agriculture in Egypt are vital resources for researchers, environmental managers and water policy planners – and for all those seeking information on wastewater reuse, green and cost-effective technologies for improving water quality. .

Due to rapid economic growth and enhancing employment opportunities, manufacturing and infrastructural projects play a vital role, especially in developing nations. Even though voluminous literature is available on environmental impact assessment (EIA), guidelines on conducting good quality assessments are lacking. It may be recognized that good EIA reports can only facilitate government decision making with sustainability considerations. The book is the result of the review of more than 150 EIA reports and the analysis of shortcomings observed by the author. It will serve to bridge the gap in the limited understanding of EIA concepts by practitioners and practical aspects by fresh graduates. The book describes the output and salient features of a good quality EIA report and case studies to facilitate professionals preparing and appraising these reports. It will be of immense use to environment ministries, EIA practitioners, EIA appraisal authorities, project proponents, academics, and NGOs, especially in the emerging economies.
