A STUDY ON OPERATION AND MAINTENANCE COST OF IRRIGATION PROJECTS IN ANDHRAPRADESH
The  water use efficiency  in irrigation sector in india is of the order of only 25%  to 35% in most irrigation system ,with efficiency  of 40% to 45% in a few exceptional cases. The problem is not due to absolute shortage of water, it is due to the absence of the proper mechanism for conservation and distribution in efficient use. At this point of view  operation and maintenance and rehabilitation costs of irrigation projects are most important  for efficient use but the system represents gross neglect and mismanagement of water resources.We have outlined the main observation for operation and maintenance cost under various sources. Where the maintenance cost, financial insufficiency as resulted in the adhoc mechanisms initiated by institutions at ground level as well as the government mindset driven by bureaucrats, unimaginativeness to optimize the maintenance of irrigation schemes. In some, it is observed that the operation and maintenance aspect has become more a ‘political and bureaucratic’ nexus. There is need to change the ‘mind set’ of policy makers to ‘re-look’ into the whole operation and maintenance institutional arrangements for the devolution financial, operation and distribution aspects.
How Participatory is Participatory Irrigation Management (PIM)? A Study of Water User Associations (WUAs) in Andhra Pradesh
It is argued that the reason for the ills of irrigation management is the alienation of farmers from the process of planning and implementation. Often 'lack of political will' is identified as the main reason for the tardy progress in irrigation reforms at the state level. Andhra Pradesh has demonstrated the political will by initiating widespread irrigation reforms through legislation. This paper, based on the situation after six years of WUAs in existence, makes an attempt to provide a comprehensive view on the status and functioning of the Water Users' Associations in the State. It is argued that while substantial amounts of money were spent on the reform process, the money was used mainly for improving the ailing irrigation systems rather than strengthening the formal institutional structures. Though some benefits in terms of increased area under irrigation in canal systems and improved quality of irrigation is evident, the sustainability of these benefits is rather uncertain in the absence of efficient institutional structures. Despite the fact that WUAs are promoted as non-political institutions, 'elite capture' and political involvement dominate their functioning. And the present trend appears to be towards further politicization of these institutions. More importantly, even after six years of their existence devolution of powers to WUAs has not taken place, as most of the important functions like assessment, collection of water charges, sanctioning of works, etc., are still in the hands of the irrigation department. In the absence of devolution of powers the WUAs are aiming for political gains rather than improving the systems. It is argued that political will is a necessary but not a sufficient condition for making the WUAs autonomous and self-sufficient. Restructuring and reforming of the State irrigation departments and the bureaucracy is critical for effective and sustainable irrigation institutions.
Ocean predictive skill assessments in the South Atlantic: Crowd-sourcing of student-based discovery
Autonomous Underwater Gliders have over a decade long history of successful regional deployments serving scientific, societal and security needs in application areas ranging from pole to pole and including the full range of water depths from shallow coastal seas to the deep ocean. Glider deployments covering the basin scale are much fewer, but are a growing capacity as demonstrated by the Woods Hole to Bermuda line that crosses the Gulf Stream, the Atlantic Crossing line that follows the Gulf Stream, and the basin circling flights now being conducted as part of the Challenger Glider Mission. The next step in the evolution of the global Challenger mission is to enable an ensemble of modelers from different institutions and agencies to participate in a meaningful way. This process with be formalized in 2014 by leveraging the data management tools of the U.S. Integrated Ocean Observing System (IOOS) and the education tools of the U.S. National Science Foundation's (NSF) Ocean Observing Initiative (OOI). The Education Visualization (EV) tools developed by the OOI's Education and Public Engagement (EPE) Implementing Organization (IO) are currently being configured through the cyber OOI net to display real time OOI glider data with intuitive interactive browser-based tools, reducing the barriers for student participation in sea exploration and discovery. Through U.S. IOOS, forecast ocean data will be harvested from the ephemeral ocean snapshots produced by an ensemble of ocean models along the same glider tracks as Challenger. The parallel observed and forecast datasets, both evolving in real time, will be accessible through the same OOI EV tools, enabling student participation in a crowd-sourced ocean predictive skill experiment. The result will satisfy one of the important goals of the Challenger mission by enabling students to assess of the quality of the ensemble of available global scale ocean models. Student research team projects that use the new model data comparison capabilities will be conducted during the summer of 2014. Students will compare an ensemble of the global ocean models along the high velocity transport pathways by gliders on basin-scale missions, such as one that traverses the northern side of the South Atlantic gyre along the Brazilian shelfbreak. The lasting impact of the Challenger mission will be a global fleet available to respond to events, an assessment of the ocean models along the fastest ocean transport pathways, and the establishment of a network of gliderports for global response.
