  • 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 ...

  • Keyhole Gardens; Positive Impact on Food Security

    World hunger is a constant problem. It has been one of the most widely discussed topics in recent years. Rapidly increasing global population, limited natural resources, and climatic changes, has resulted in the need for a sustainable increase in food production. Scientists, governments, and organizations across the world are working together to bring innovations and good farming practices which ...

  • Quantification of soil surface evaporation under micro-scale advection in drip-irrigated fields

    The objective of this study is to quantify soil surface evaporation under micro-scale advection in drip-irrigated fields. A numerical model for estimating soil surface evaporation under micro-scale advection, assuming drip-irrigated fields, is introduced. Results indicate that the soil surface evaporation changes spatially. Soil surface evaporation at the upwind edge of wet soil portions adjacent ...

  • 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 ...

  • Variable Demand Irrigation

    2,000 GPM Turbine pump supplies four 500 GPM pivot sprinklers After three VFD’s failed in less than five years, this farmer decided to try a Cycle Stop Valve. Three years later there have been no problems with the CSV. The system is able to supply one pivot just as easily as all four pivots when ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • The effect of winter flood irrigation with saline water on groundwater in a typical irrigation area

    Flood irrigation in the winter has been widely applied in northwest China for several years, but little attention has been paid to the flood irrigation program to date. In order to seek a reasonable irrigation quota, a flood irrigation experiment using two common quotas (1,800 and 1,200 m3 ha−1) was conducted in an area irrigated by saline water in the Nanjiang basin with shallow ...

  • Study on the joint probability distribution of irrigation water volume and irrigation water efficiency

    Using the copula method, the joint probability distribution of irrigation water volume and efficiency is constructed, and their joint return period is also described to reveal the encounter probability of irrigation water volume and efficiency. Furthermore, the conditional probability of irrigation water efficiency with different water volumes is built to show the quantitative effects of flow on ...

  • 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 ...

  • Effect of deficit irrigation and fertilization on cucumber

    Soil water budgets are essential in determining the proper timing and amount of irrigation. Organic fertilizers can be substituted for commercial fertilizers; however, information is sparse on the interaction of irrigation management and nutrient source on cucumber (Cucumis sativus L.) production. This study evaluated nutrient source and irrigation management on growth and yield of cucumber grown ...

  • Irrigation Systems and Practices in Challenging Environments

    The book Irrigation Systems and Practices in Challenging Environments is divided into two interesting sections, with the first section titled Agricultural Water Productivity in Stressed Environments, which consists of nine chapters technically crafted by experts in their own right in their fields of expertise. Topics range from effects of irrigation on the physiology of plants, deficit irrigation ...

  • Monitoring Water Resources Beyond Irrigation

    Over the past year, California’s governor has taken unprecedented action, requiring Californians to drastically cut potable urban water use. While the restrictions may seem harsh to some, it actually provides an opportunity for building managers and community association boards to implement an effective long-term water conservation program. And the result can be significant dollar savings. ...

  • 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 ...
