  • 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 ...

  • The sustainability challenge: Meeting the needs of the water-energy nexus

    In 2009 Davos World Economic Forum reported that the world is quickly heading towards “water bankruptcy.” As global population soars, food, energy and freshwater are becoming increasingly scarce. Water, whether for potable or industrial use, is limited, and some supplies are not useable. The need for water in the developed world is high. Two-thirds of all the water consumed is used ...

  • The benefit of electrocoagulation in water treatment for agriculture and aquaculture

    Now a day’s one of the most intensive and the best field due to which the entire human kind can survive is the field of agriculture and aquaculture. The agriculture industry is a water requirement industry and is in a need of constant free contaminant water supply and so is in fish cultivation. And in order to provide this contaminant free water supply it requires a large scale of water ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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. ...

  • Biotechnology for Environmentally Safe Agriculture

    Issue: In Europe some uses of biotechnology are meeting vocal opposition from certain quarters. Nevertheless, the vast amount of knowledge acquired recently in biology can be used to develop and apply biotechnology for an environmentally safe agriculture. Public acceptance and a new policy impetus can serve to promote the introduction of safe and competitive agricultural technologies that have a ...

  • 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, ...

  • Peak Water?

    Agriculture used to mean unexciting investments in commodities. Now Silicon Valley, for instance NewSeed Advisors and KPCB, are looking for the “next great idea” in farming efficiency. It’s Agriculture 2.0, a.k.a. “ag” app. At the same time companies like Goldman Sachs and several sovereign funds are investing in agricultural land. Why is this!? ...

  • 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 ...
