  • 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 ...

  • Knowledge of Farm Practices – The Key for Successful Farming

    Agriculture plays an important part in the world economy. One-third of the economically active population obtains its livelihood from agriculture. In Asia and Africa, millions of small-scale farmers, fishermen, and indigenous people produce most of the food consumed worldwide, in most cases on very small plots of land. Agriculture is increasingly called upon to address a wide range of critical ...

  • 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 ...

  • 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 ...

  • 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. ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Need for national soil policies for developing countries - some facts

    As a soil scientist working for more than 25 years, I am very much concerned with soil protection and conservation. In this process, I started collecting information related to national soil policies of different countries. To my surprise I could not get a well defined national soil policy for any one of the developing country? A developing country can be defined as , that country which has a ...

  • The Importance Pressure Management on Agricultural Irrigation Applications

    Irrigation systems world wide are dependent on sound pressure management techniques which are normally incorporated at the design phase of the project. This holds true whether you are designing agricultural irrigation systems incorporating drip, micro spray, sprinkler or pivot systems and has similar ramifications for turf irrigation or even golf course irrigation systems. Automatic ...
