  • Irrigation challenges in the sub-humid US Mid-South

    Irrigated area in the Mid-South USA continues to increase and now totals four million ha. Because of low available water holding capacities and shallow root-limiting layers in many soils, irrigation management is difficult. Water quality and water use efficiency impacts under irrigation are poorly understood, but comprehension is necessary if conversion from groundwater to surface water supplies ...

  • Effect of O3 and O3/H2O2 on algae harvesting using chitosan

    We examined the effects of pre-oxidation using ozone (O3) and a combination of O3 and hydrogen peroxide (O3/H2O2) on algae suspensions and their harvesting. Inactivation of algae cells, release of intracellular organic matter (IOM), mineralization of extracellular organic matter (EOM), and changes in molecular weight distribution of EOM were found after ...

  • A sub-economy in Montreal

    This paper explores the size and socio-demographic characteristics of a Jewish sub-economy found in Montreal in the late 1970s and 1980s, along with other features of Jewish economic activity in Canadian cities. It is found that there is a much higher than expected degree of intra-group economic activity found linking Jewish entrepreneurs, employers, workers, suppliers, and customers. This ...

  • Seeds of change in sub-Saharan Africa

    In the late 1900s, as per-acre grain yields moved to 3 metric tons per hectare in South and Southeast Asia and Latin America, 5 metric tons per hectare in China, and 10 metric tons per hectare in North America, Europe and Japan, there’s one place where production stagnated big time: sub-Saharan Africa, where loss of soil fertility on small farms trapped grain production at an unsustainable ...

  • 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 ...

  • Synthesis, characterization and photocatalytic activity of 1D TiO2 nanostructures

    Nanowire/nanorod TiO2 structures of approximately 8 nm in diameter and around 1,000 nm long were synthesized by alkaline hydrothermal treatment of two different TiO2 nanopowders. The first precursor was TiO2 obtained by the sol-gel process (SG-TiO2); the second was the well-known commercial TiO2 P-25 (P25-TiO2). Anatase-like 1D TiO2 ...

  • 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 ...

  • Empowering Women in Irrigation Management

    This case study aims to highlight, within the context of a Gender Pilot of the Peru Sierra Irrigation Project, how women's different needs were identified to facilitate their access to training and to increase their participation in the management of water users' organizations. It follows the diagnostic participatory discussions around the importance for communities to include women in water ...

  • 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 ...

  • 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 ...

  • Morocco: Irrigation water pricing policy of large scale irrigation projects

    In Morocco, the consequence of increased industrialization and a rapidly growing population accentuated by a progressive shift from rural to urban living. This resulted in the growth of requirements for the quality and quantity of water resources, their more intensive and comprehensive use. The ...

  • Distribution of moisture and salinity under deficit irrigation and irrigation water salinity in an alternative trickle irrigation system of tape

    This study was performed to investigate the horizontal and vertical distribution of soil moisture and salinity using an alternative trickle irrigation system of drip tape. Four main treatments consisting of 100, 80, 70, and 60% of the plants’ water requirements and three sub-treatments of 2.1, 4.6, and 10.2 dS/m, were conducted. Following irrigation, the soil moisture and salinity ...

  • 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 ...

  • 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 ...

  • Disposal of De-Icing Effluents By Irrigation

    At Zurich Airport (Switzerland) alcohols, as well as urea in small quantities, are utilized for de-icing in order to maintain the air traffic during winter. To purify the accumulated de-icing effluents a new, groundbreaking, cost-effective (investment and maintenance) method was developed which has been successfully applied since winter 2000/2001. The de-icing effluents are irrigated onto the ...

  • An analysis of groundwater irrigation expansion in India

    This paper suggest that groundwater irrigation expansion in India is driven mainly by the population pressure and not necessarily dependent on the change in surface water irrigation. However, in the districts irrigated by Groundwater only, our findings indicate that the marginal effect of groundwater on Gross Irrigated Area (GIA) is lower than that in the district endowed with both surface and ...
