Agricultural Irrigation and Land Reclamation

Research activities on efficient and sustainable irrigation management, because of rapid climate change, population growth and decrease in water resources for agricultural, and increase in industrial demands, have been carrying out in the Department of Agricultural Irrigation and Land Reclamation. The main responsibility of the department is to carry out research projects about water consumption of crops grown in Aegean Region, irrigation water requirements, irrigation methods and the other subjects deal with agricultural water use and/or drainage. The other task is to provide the knowledge, data and irrigation techniques for investor institutions, farmers and farmer organizations.

General Goals

To increase production and improve quality of irrigated agriculture, by the cost effcetive design, operation and management of on-farm irrigation and driange systems

To reduce the risk to irrigated agriculture from competitive demands for water by maximising the water utilization efficiency of resources used for irrigation, by improvements to irrigation efficiency and by the re-use of irrigationand other waste water flows.

To reduce the riak of waterlogging and salinization on new irrigated lands, and to restore damaged lands in existing systems by the design of appropriate mitigation and rehabiltion measures.
