  • Agriculture Plant Nursery - Case Study

    Challenge A plant nursery company had water quality issues from the well water source that there were using for irrigation purposes in their plant growing operations. These water quality issues including total dissolved salts (TDS) around 2500 mg/l, as well as turbidity, mineral hardness and microbiological contaminants. The plants were slow growing. ...

  • Eima 2016: A success for irrigation

    Energy saving and maximum efficiency are the cardinal points of agriculture 2.0. Today, through the micro irrigation and subsurface irrigation, agricultural production reached a high level of efficiency that assures quality and quantity. “Micro-irrigation”, or drip irrigation, is a method which allows the farmer to give the same amount of water to the ...

  • Food and water insecurity: re-assessing the value of rainfed agriculture

    ABSTRACTRainfed agriculture has potential to produce needed cereals for the growing populations of West and Central Asia even though rainfed agriculture is perceived as risky. The value of rainfed agriculture to produce competitively should be re-assessed. This requires the concerted efforts of farmers, researchers, and policy makers to work on the technical factors that determine agricultural ...

  • Watering Scarcity: Private investment opportunities in agricultural water use efficiency

    This report was prepared by Rabobank in collaboration with the World Resources Institute. In many regions around the world, demand for fresh water now outstrips renewable supplies. Water scarcity is projected to worsen considerably due to a combination of factors such as population increase, higher incomes and changing lifestyles, pollution, and climate change. Agriculture is by far the biggest ...

  • Tunisia: Reform of irrigation policy and water conservation

    An arid country with limited water resources, Tunisia depends heavily on irrigated agriculture. The sector contributes 30-40% of the value of agricultural production, and is highly important in some regions. However, abstraction for irrigation accounts for 83% of the available water ...

  • GWT Case Study - Agriculture Processing Sector

    Application Case Studies - Agriculture Plant Nursery Challenge A plant nursery company had water quality issues from the well water source that there were using for irrigation purposes in their plant growing operations. These water quality issues including total dissolved salts (TDS) around 2500 mg/l, as well as turbidity, mineral hardness ...

  • Can drip irrigation keep the Prairie Profitable?

    The use of flood and center pivot irrigation of crops via the waters of the Ogallala Aquifer is as hot a discussion topic as the current drought. To many who mine the aquifer to make a living, trying to keep a profitable way of life sustainable in a time when the broader public is seeking more conservation of resources yet wanting inexpensive, plentiful and safe food is problematic. Perhaps it's ...

  • From (cyber)space to ground: new technologies for smart farming

    Increased water demand and climate change impacts have recently enhanced the need to improve water resources management, even in those areas which traditionally have an abundant supply of water, such as the Po Valley in northern Italy. The highest consumption of water is devoted to irrigation for agricultural production, and so it is in this area that efforts have to be focused to study ...

  • The need for a professional network of agricultural and biosystems engineers in Africa

    Agricultural productivity in Africa remains the lowest in the world, but recent concerns about food insecurity, rising food prices and resource depletion have spurred world–wide interest about the role of African agriculture in feeding Africa and the world. Majority of world's uncultivated agricultural land is in Africa, yet the capacity to harness this resource remains limited due partly ...

  • A policy option for valuing irrigation water in the dry areas

    Participants at the international conference on policies for water and food security in the dry areas, held in June 2013, agreed that, given the fast pace of depletion of groundwater, the issue of water valuation in the dry areas is no longer one of whether or not, but rather of how. Policies that have been or are perceived to have adverse effects on the cost of agricultural production or food ...

  • Potential water savings associated with agricultural water efficiency improvements: a case study of California, USA

    This study analyzes the potential for water savings from irrigation efficiency improvements in California, USA. We model water savings associated with three efficiency scenarios in wet, average and dry water years. The ‘efficient irrigation technology’ scenario shifts a fraction of the crops from flood irrigation to sprinkler and drip systems; the ‘improved irrigation scheduling’ scenario uses ...
