  • Balancing Agricultural, Urban, and Environmental Water Needs in Water Resources

    The Lower Colorado River Authority (LCRA) – San Antonio Water System (SAWS) Water Project is a plan to conserve water, develop groundwater, and capture excess and unused river flows to meet future water needs for two neighboring regions in Texas. Agricultural and other rural water needs would be met on a more reliable basis in the lower Colorado River basin through water conservation, surface ...

  • Reuse: Agriculture

    Agronomic and water quality considerations Water use for agricultural irrigation is the largest component of water use in most countries and is more than 70% of human water use in drier countries. Use of recycled water for irrigation requires consideration of soil types, groundwater levels, soil and water chemistry, nutrient loads, limits on chemicals, the salt tolerance of ...

  • Breaking the dilemma of agricultural water fee collection in China

    Low agricultural water fee collection rates are a problem commonly faced by many developing countries and this is a problem faced by China as it enters the new century. There are two main problem-solving strategies used in different areas of China: increasing the water fee collection rate, or exempting people from paying the water fee. In those areas where the first strategy is pursued, local ...

  • Plant Sciences in Agriculture

    Plant pathogens Microorganisms, also called as microbes, live in every part of the biosphere, including soil, water, and air. Plant pathogens are the microbes that infect plants and cause diseases. In history, some plant diseases led to tremendous negative impacts on society. In 1845, potato blight disease was prevalent in all potato growing regions in Ireland. Phytophthora infestans, a ...

  • 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 ...

  • Technical coefficients of direct use of water in monetary terms for agriculture and urban water use

    The San Francisco Integration Project is a Brazilian government project aiming to bring water to the semiarid region of the northeast. The project provides funding for two diversions of the San Francisco River, supplementing the supply of local water in four Brazilian states. The Piranhas-Açú and Jaguaribe basins will become the largest recipients of these water deliveries. In this paper, we ...

  • Estimating water use efficiencies for water management reform in Southern Alberta irrigated agriculture

    Water use technical efficiency (WUTE) and three definitions of water use economic efficiency (WUEE) were estimated for the four river sub-basins that encompass the 13 irrigation districts in Southern Alberta over a 5-year period: 2004–08. The average level of WUTE varied from 3.5 to 6.2 Mt dam−3. The gross economic value of crop production varied from Canadian (C)$345 to ...

  • 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 ...

  • China: agricultural production and groundwater

    As in many parts of the People’s Republic of China, Shanxi Province is experiencing reduced water security for the agriculture sector. Changing climate conditions, including reduced rainfall, are increasing reliance on groundwater resources in the province. Unsustainable groundwater use for food production intensifies the impacts of climate change, and cost-effective adaptation responses ...

  • A water balance approach for assessing the potential source of water in Dohuk Dam for agricultural, domestic and tourism purposes

    Water balance approaches have been widely used to stimulate and forecast the average runoff and river discharge in small- and medium-sized basins. The analysis of water balance for Feesh Khabour River and Dohuk Dam catchment areas needs to be verified. This study used 24 alternative scenarios for assessing the robustness of adaptation decisions to water management practices. The discharge of ...

  • One-Quarter of World’s Agriculture Grows in Highly Water-Stressed Areas

    All living creatures need two things to survive: food and water. A new WRI analysis shows just how much tension exists between those two essential resources. A new interactive map from WRI’s Aqueduct project reveals that more than 25 percent of the ...

  • How to create resilient agriculture

    Durable food security and agricultural growth depend on development strategies with resilience built in from the start, says Gordon Conway. Economic growth with resilience to environmental threats will be central to the agenda of the UN Conference on Sustainable Development (Rio+20) in June this year, which aims to map out a pathway of sustainable development for the planet. ...

  • Pressure Measurement For Agricultural Applications

    A couple months ago we took a brief look at how the agriculture industry is turning to automation and data to help monitor product and resource levels, enabling farmers and ranchers to be proactive, rather reactive, about the needs and conditions of their businesses. We all agreed that there are plenty of opportunities for level measurement in the modern agriculture industry. But what of pressure ...

  • Direct Potable Reuse: Benefits for Public Water Supplies, Agriculture, the Environment and Energy Conservation

    INTRODUCTION Direct potable reuse (DPR), in which purified municipal wastewater is introduced into a water treatment plant intake or directly into the water distribution system, is becoming an increasingly attractive alternative to developing new water sources (Tchobanoglous et al., 2011). The rationale for DPR is based on the technical ability to reliably produce purified water that ...

  • New approaches are needed for another Green Revolution

    Twenty-first century agriculture needs low-input advances like the System of Rice Intensification, says Norman Uphoff. According to the principle of diminishing returns, continuing to produce something in the same way, with the same inputs and technology, ...

  • The CAMBI process and agriculture, a sustainable solution?

    Abstract Both public acceptance and interest from farmers for spreading biosolids from waste water treatment plants (wwpt) on arable land, are dependent on some fundamental criteria. These criteria are, however, quite straightforward. The biosolids should be safe, easy to handle, a well documented source of plant nutrition, without disagreeable odours and easily available. A big part of the ...

  • Irrigation Systems 101: What you need to know

    In the perfect scenario everyone could rely on rainwater for their farming practices, but this is not always the case. This is why employing the right choice from the different irrigation systems available is crucial for agricultural success. Irrigation systems are basically an artificial way to provide water to fertile soil for agricultural purposes. Crop irrigation is necessary to ...
