  • 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 ...

  • 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 ...

  • The viability of treated piggery wastewater for reuse in agricultural irrigation

    Background The swine production is a very important economic matter, occupying prominent position in the worldwide market. However, it appears as the greater impacting activity for the water resources. Researches point a swine manure production of 105.6 million m3/year in Brazil, which resulted in a piggery wastewater rich in solids, nutrients, heavy metals, and pathogens. Moreover, ...

  • 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 ...

  • Irrigated agriculture and groundwater resources – towards an integrated vision and sustainable relationship

    Globally, irrigated agriculture is the largest abstractor, and predominant consumer, of groundwater resources, with large groundwater-dependent agro-economies now having widely evolved especially in Asia. Such use is also causing resource depletion and degradation in more arid and drought-prone regions. In addition crop cultivation practices on irrigated land exert a major influence on ...

  • The transport of three emerging pollutants through an agricultural soil irrigated with untreated wastewater

    The aim of this work was to determine the mobility of naproxen, carbamazepine, and triclosan through a wastewater-irrigated agricultural soil. Transport experiments were carried out using undisturbed soil columns taken at 10 and 40 cm depths. The mobilization of the pollutants was evaluated using two hydrological regimes transient flow for superficial columns and steady-state conditions for the ...

  • Wastewater retreatment and reuse system for agricultural irrigation in rural villages

    Climate changes and continuous population growth increase water demands that will not be met by traditional water resources, like surface and ground water. To handle increased water demand, treated municipal wastewater is offered to farmers for agricultural irrigation. This study aimed to enhance the effluent quality from worn-out sewage treatment facilities in rural villages, retreat effluent ...

  • 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 ...

  • Everglades Agricultural Area Reservoir A-1 Management of Runoff for Everglades Restoration and Agricultural Irrigation

    THE PROBLEMIncreased development in central and south Florida has altered the natural drainage pattern of the Florida Everglades National Park (Everglades). This alteration has resulted in excess water during the wet season and insufficient water flowing through the ecosystem during the dry season, increased water supply demands, degrading water quality, and declining estuary health and wading ...

  • Irrigation by Sewage Effluents in Yemen

    Yemen is the least advanced country among Middle East Countries in the sewage reuse and safety control. The current sewage effluent quality in Yemen is generally poor as none of the existing sewage treatment plants produces effluents comply with the effluent quality regulations. The oxidation and stabilization ponds are considered the most appropriate for the warm climate conditions in the ...

  • Arsenic in irrigated paddy soils

    Natural arsenic pollution of drinking water has been reported from over 70 countries world-wide, affecting an estimated 150 million people (Ravenscroft et. al., 2008). About 50 million of these people live in Bangladesh, 30 million in India and 33 million in six other countries of south and south-east Asia. It has recently been recognised that arsenic-contaminated groundwater used for irrigation ...

  • Incentives and instruments for sustainable irrigation

    This book looks at Sustainable Irrigation in a holistic way, considering the multidisciplinary objectives of sustainable agriculture, sustainable water management, sustainable water infrastructure, sustainable irrigation communities and a sustainable environment, the need to reallocate water between competing users, and the need for water and food security in an environment of scarcity. It does ...

  • The Environmental Impacts of Irrigation in the European Union

    The purpose of the studies is to explore the relationship generally between agricultural sectors and practices and the environment. The sectoral studies describe the environmental relationship, the practical possibilities to improve that relationship and the various options (with agri-environmental measures) to establish environmental gains. They should contribute to an informal debate and ...

  • 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 ...

  • Deficit irrigation optimization of cotton with aquacrop

    Given the current pressures to reduce irrigation water use, it is important to optimize the use of water in irrigated agriculture. This work was aimed at determining the optimum level of applied irrigation water (AIW) for cotton (Gossypium hirsutum L.) production in southern Spain under several climatic and agricultural policy scenarios. To generate the yield response to variations in AIW, we ...

  • Fertility status, trace elements and heavy metal pollution of agricultural land irrigated from the Gediz River

    The effect of the Gediz River, polluted by industrial and domestic wastes, on fertility status and trace elements and heavy metal pollution of agricultural land irrigated from this river was investigated. For this purpose, soil samples were collected in August 1998 between the source of the Gediz River (Murat Mountain) and its mouth (Aegean Sea). Soil samples were collected from 12 different ...

  • Potential drawbacks associated with agricultural irrigation with treated wastewaters from desalinated water origin and possible remedies

    Over 90% of the water supplied in the coastal region in Israel in 2013 (600 Mm3 y−1) will be from desalination plants. The wastewater generated from this water (>400 Mm3 y−1) is planned, after proper treatment, to be reused for agricultural irrigation, making this low-salinity water the main agricultural-sector future water source. In this respect both the Mg2 +  concentration and the Sodium ...

  • Irrigation planning for sustainable rain-fed agriculture in the drought-prone Bundelkhand region of Madhya Pradesh, India

    The recent spells of recurrent and consecutive droughts in the Bundelkhand region in Central India have led to uncertain rain-fed agriculture and its sustainability. Adequate knowledge of starting dates and lengths of dry spells has a considerable importance in rain-fed agriculture, irrigation planning, and various decision-making processes. The long dry spells incur heavy costs to the affected ...
