A growing body of international findings shows that irrigation management transfer can actually contribute to rural poverty by aggravating existing inequities within irrigation schemes or introducing new ones. New research looks at how the transfer of irrigation management from governments to farmers can be done in a way that benefits poor farmers.

deficit- irrigation is one of the measures for water saving and optimum application of water in surface irrigation. however, lack of enough evidences, doubts on the proper application of deficit- irrigation, dissemination of research results and its application by the farmers are of practical challenging issues. this paper summarizes and analyzes some research results on deficit- irrigation in ...

The use of software agent systems and technologies to simulate water resources management scenarios and improve the engagement of stakeholders in policy making is gaining paramount importance. Such importance originates from two main concerns or change agents. Firstly, the context of water management is becoming highly complicated due to the intensity of connections with other systems, the dive...

Irrigation water management is crucial for agricultural production and livelihood security in many regions and countries throughout the world. Over the past decades, controversial and conflictladen water-allocation issues among competing municipal, industrial and agricultural interests have raised increasing concerns. Particularly, growing population, varying natural conditions and shrinking wa...

Traditional water-saving irrigation management turns on water pump in a settled interval decided by grower’s experience. The method just saves water on the back of losing yield. In order to result the problem, a kind of greenhouse efficient irrigation management system based on Evapotranspiration has been developed. The system includes greenhouse environmental monitoring subsystem, irrigation a...

The adoption of improved surface irrigation design and management practices is inhibited both by a low awareness amongst irrigators of the variables affecting irrigation performance and the difficulty of quantifying the benefits associated with alternative practices. Simulation modelling may be used to address both of these issues. This paper reports on the use of the surface irrigation model S...

In recent years decentralized development approaches have gained prominence in the agricultural sector. A host of community based watershed management projects have been implemented that encourage community organizations to undertake management of previously government controlled irrigation systems and forests. Community organizations have been given the responsibility of managing water distrib...

For more efficient field operation and management of precision irrigation, Management Zone Analyst (MZA) software was used to delineate irrigation management zones. MZA is a simple and fast software for subfield management zone delineation on the basis of fuzzy c-means clustering algorithm. The measured soil physical properties of Chahayang Farm in Heilongjiang Province were taking as data sour...

Background: Different approaches are available to irrigate the arterial catheter, such as continuous and intermittent techniques. However, there is a disagreement regarding the most appropriate method. Aim: this study aimed to compare the effect of two continuous and intermittent irrigation methods on complications of arterial catheter and partial thromboplastin time (PTT) in patients with coro...

abstract the present study was carried out for developing and evaluating of the optimization model of cropping pattern in irrigation networks using analytical hierarchy process (ahp). the model was programmed into two sub-models. the objective of the first sub-model was ranking of crop appropriately, and the objective of the second sub-model was ranking of cropping area of each crop. ten criter...
