  2. 1. Condensation irrigation : a combined system for desalination and irrigation

    Author : Jenny Lindblom; M. Thameur Chaibi; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : Condensation Irrigation (CI) is a new irrigation method that combines desalination and subsurface irrigation by making use of saline water for supplying clean irrigation. In this system, solar stills are used for evaporating non-potable water, and the formed vapour heats and humidifies the ambient air above the water surface. READ MORE

  4. 2. Irrigation water management : A performance study of the Rahad scheme in Sudan, 1977-1996

    Author : Nighisty Ghezae; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economic history; Rahad scheme; irrigation management; water supply activities; agricultural extension activity; performance assessment; main system management; on-farm management; organizational structure; Ekonomisk historia; Economic history; Ekonomisk historia; Ekonomisk historia; Economic History;

    Abstract : The central objectives of this study is to assess the performance of irrigation water management of the Rahad scheme in Sudan between 1977 and 1996. The study assesses how well the scheme has succeeded in achieving irrigation management objectives using the criteria of productivity, equity, cost recovery and environmental stability. READ MORE

  5. 3. Condensation irrigation : simulations of heat and mass transfer

    Author : Jenny Lindblom; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : There is a growing water demand in the world. Along with the deterioration of existing water supplies, the escalating world population leads to the assumption that two out of three people will lack sufficient freshwater by the year 2025. READ MORE

    Abstract : Water constraints for humans and nature are gaining more and more public attention as a critical environmental dilemma that needs to be addressed. When aquifers and rivers are running dry, the debate refers to an ongoing “world water crisis”. READ MORE

  7. 5. Evaluation of Modern Irrigation Techniques with Brackish Water

    Author : Tarek Selim Aboulila; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Soil water; Soil Salinity; Drip irrigation; HYDRUS-2D 3D; El-Salam Canal; Egypt.;

    Abstract : Modern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. READ MORE
