Adapting to Water Scarcity: Effects of Irrigation Management
… of structural variables (e.g., central vs. local management of irrigation water, location of village), psychological variables (e.g., risk perceptions, self-efficacy), and adaptation on crop yield. We tested a psychology-based model that focused on risk perceptions and efficacy beliefs by …

NeuroFuzzy modelling for conflict resolution in irrigation management
Management of large-scale irrigation schemes is more complicated than commonly recognized. Irrigation management involves complicated social, organizational, legal, and economical issues in addition to the undoubtedly important technical matters and environmental aspects. Management decisions have …

Irrigation management effects on nitrate leaching and mowing requirements of tall fescue
Irrigation management may influence nitrate leaching under tall fescue (Festuca arundinacea) and also affect its mowing requirements. Two experiments were conducted on tall fescue growing on a Chase silt loam soil near Manhattan, Kansas. Each experiment was arranged in a split-plot design, with …

Evaluación de alternativas de gestión del regadío tradicional para la reducción del impacto agroambiental
… work analyzed the repercussions that alternative irrigation management can cause on agrosystems and its near environment. For thus, water use and agri-environmental impact on Irrigation District nº V of Bardenas (Zaragoza, Spain; 15,500 ha) was studied by analyzing its drainage network (2000 and …

The development and application of analytical techniques for planning of irrigation systems
Computer-based techniques for assessment of irrigation water supply and demand are illustrated using a 140 x 75 km discrete element representation of the Canterbury Plain, New Zealand. A versatile soil moisture accounting model is developed and used to simulate soil moisture status throughout the …

Reimagining planning of irrigated agriculture in the Indus River Basin, Punjab, Pakistan
… Punjab has identified 'integrated water resource management' as the guiding paradigm for achieving efficient, equitable and environmentally sustainable use of natural resources in the province. However, no clear roadmap for how multi-sectoral, 'integrated' resource management and governance can be …
