Effective and efficient irrigation practices are critical to successful rice production and to the sustainability of rice production. To better understand how to address the issue of water management in rice we initially installed water flow meters on two studies that were designed to evaluate disease incidence using fertility, variety/hybrid, and water management as treatment variables. One st...

The capacity to adaptively manage irrigation and associated contaminant transport is desirable from the perspectives of water conservation, groundwater quality protection, and other concerns. This paper introduces the application of a feedback-control strategy known as Receding Horizon Control (RHC) to the problem of irrigation management. The RHC method incorporates sensor measurements, predic...

The study on ‘‘pro-poor intervention strategies in irrigated agriculture in Asia’’ by Hussain (2005) shows that, in 26 major and medium-size canal irrigation schemes in Asia, irrigated areas average 20% lower poverty than adjacent rainfed areas; gains are more with pro-poor management of water for farming (PPMWF) and where distribution of farmland or farm water is more equal. These findings, an...

Within the Project – “Developing Strategies for Regulating and Managing Water Resources and Demand in Water Deficient Regions (WSM)” funded by the EU in 5 Research Framework Program, the Ribeiras do Algarve River Basin was chosen as a case study to develop a DSS for planning purposes. Located in the southern stretch of the Portuguese territory, crucial conflicts do exist between tourist and agr...

Equitable distribution of water is a growing source worry, and concerns systems’ managers as water-stressed areas steadily increase situations scarcity are becoming more frequent. The problem goes beyond just the sector globally affects many countries’ economies since resources have multiple uses (i.e., power generation, irrigation, etc.). One various strategies to overcome periods extreme even...

A proposal for energy management in an off-grid photovoltaic pumping and irrigation system is presented and evaluated for a specific case study. The system is assumed to be based on off-the-shelf components (photovoltaic panels, battery banks, DC/AC converters, relays, submergible pumps, etc.), with a microcontroller-based energy management system, deciding when to disconnect the load from the ...

We present an innovative approach to explore water management options in irrigated agriculture considering the constraints of water availability and the heterogeneity of irrigation system properties. The method is two-folds: (i) system characterization using a stochastic data assimilation procedure where the irrigation system properties and operational management practices are estimated using r...

the main purpose of rainfed farming is increasing the water productivity by applying suitable agricultural management including single irrigation (si) and panting time for wheat varieties. in order to study the si optimization and determination its optimal program, a field experiment was conducted as split-split plot based on a randomized complete block design with three replications for differ...

Despite of the water use increment for other sectors than agriculture, the water use for irrigation is the main water consumer in global scale. However, irrigation has been pressured by the civil society to improve water use efficiency in agriculture, to prevent water scarcity for human population that grows continuously, mainly in developing areas of the planet. On the other hand, the irrigati...
