Gain-scheduling multivariable LPV control of an irrigation canal system

The purpose of this paper is to present a multivariable linear parameter varying (LPV) controller with a gain scheduling Smith Predictor (SP) scheme applicable to open-flow canal systems. This LPV controller based on SP is designed taking into account the uncertainty in the estimation of delay and the variation of plant parameters according to the operating point. This new methodology can be applied to a class of delay systems that can be represented by a set of models that can be factorized into a rational multivariable model in series with left/right diagonal (multiple) delays, such as, the case of irrigation canals. A multiple pool canal system is used to test and validate the proposed control approach.Peer ReviewedPostprint (author's final draft

Predictive Adaptive Control of water level in canal pools

A case study on the use of a predictive adaptive algorithm to control pool level in a pilot water distribuition canal is described. The algorithm is a modification of the basic MUSMAR controller that includes parallel integral action and, in the case of multiple pools, feedforward action to coordinate the gates. Experimental results in the case of a single pool and simulations for multiple pools are presented. The contributions of the paper stem from the explicitation of rules for tuning the adaptive controller in a practical situation and from the coordination of different pools using reduced complexity controllers and feedforward in a multivariable settin

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.participatory, Irrigation Management, water, Andhra Pradesh

Rural Institutions and Planned Change in Agriculture: A Comparative Perspective in Two Punjabs

Agricultural change in the Indian and Pakistan Punjabs has been brought about by their respective governments through formal organisations—cooperatives, credit banks, agriculture departments and/or special interest groups at the local level. The changes produced during 1960s and in subsequent period were dramatic but unsettling. Many have argued that the achievement of agricultural change in the region has depended to an important extent on the effectiveness of rural institutions in executing their role as agents of planned change.1 The present paper seeks to review the debate on the role of rural institutions in producing social and economic changes in the agrarian sectors of the Indian and Pakistan Punjabs and present some of the data which have stimulated this debate. The paper commences with an overview of the agrarian change in the two Punjabs. Then the programmes of planned change in the two regions are described, and the particular institution of change—cooperatives, credit banks, agricultural departments etc. are discussed in detail. At the specific level, the study aims at delineating the role played by rural institutions in initiating, stimulating, sustaining or retarding change in agriculture sectors of the two Punjabs. The role of rural institutions as a policy instrument for the promotion of agricultural expansion is examined. And finally the paper points out the implications of the past experience for the future role of rural institutions in the two Punjabs.

INSTITUTIONAL CHANGE IN INDIAN AGRICULTURE

Globalization, privatization and scientific advancements pose new challenges and opportunities for the development of Indian agriculture. The emerging paradigm shifts focus to creation and application of new knowledge for agricultural development and global competitiveness. To facilitate this shift and realize greater economic efficiency, a new set of responsive institutions should emerge. This volume discusses the direction of institutional change in Indian agriculture. The roles of the state, markets and collective actions are examined for evolving the knowledge-intensive agriculture. The contributed papers from a number of leading researchers cover the institutions for R&D, land and water resources, credit, marketing, trade and agro-processing.Industrial Organization, International Development,

State-community synergies in development : laying the basis for collective action

If states would interact more synergistically with communities, they could tap local energies and resources for development-- and help create a development-oriented society and polity in the process. The authors analyze experience in several countries to identify the actions required for state-community synergies in development. Two actions that seem especially important: 1) Broadening the distribution of power within communities, to facilitate collective action and reduce the potential for local capture. In rural areas, much can be done by expanding access to credit, strengthening tenants'rights, and expanding non-crop sources of income. 2) Creating state-community alliances toimprove the effectiveness of local public sector institutions and the delivery of services. Case studies from East Asia and Latin America show that such alliances can effect rapid improvements in local institutions, benefiting not only communities but also politicians seeking support and legitimacy. Local bureaucratic reform, combined with more egalitarian community social organizations, allows the creation of powerful coalitions and synergies for rapid, self-sustaining development. This model has been used to achieve outcomes ranging from better health care and drought relief to the generation of agrarian and industrial economic growth. In China and Taiwan, China, these state-community synergies helped produce not only for local consumption but for a rich export market. The cases show that with creative political thinking it is possible to effect rapid change even in poor institutional settings. The Brazilian experience shows how difficult institutional change is in highly inegalitarian settings, but also how such obstacles can be overcome by changes designed to bring grassroots electoral pressure to bear on local government. Experience elsewhere shows, however, how fragile such efforts can be if political support from above is prematurely withdrawn.Health Economics&Finance,Environmental Economics&Policies,Decentralization,Banks&Banking Reform,Agricultural Knowledge&Information Systems,Environmental Economics&Policies,Health Economics&Finance,Poverty Assessment,Governance Indicators,Agricultural Knowledge&Information Systems

Fostering community-driven development - What role for the State?

States can do much to tap community-level energies, and resources for development, if they seek to interact more synergistically with local communities. The broader spin-off is creating a developmental society, and polity. Using case studies from Asia and Latin America, the authors show how: 1) State efforts to bring about land reform, tenancy reform, and expanding non-crop sources of income, can broaden the distribution of power in rural communities, laying the basis for more effective community-driven collective action; and 2) Higher levels of government can form alliances with communities, putting pressure on local authorities from above, and below to improve development outcomes at the local level. These alliances can also be very effective in catalyzing collective action at community level, and reducing :local capture"by vested interests. There are several encouraging points that emerge from these case studies. First, these powerful institutional changes do not necessarily take long to generate. Second, they can be achieved in a diversity of settings: tightly knit or loose-knit communities; war-ravaged, or relatively stable; democratic, or authoritarian; with land reform, or (if carefully managed) even without. Third, there are strong political payoffs in terms of legitimacy, and popular support for those who support such developmental action.Water Conservation,Decentralization,Agricultural Knowledge&Information Systems,Environmental Economics&Policies,Community Development and Empowerment,Poverty Assessment,Governance Indicators,Environmental Economics&Policies,Agricultural Knowledge&Information Systems,Health Economics&Finance

Claims of the City? Rights of the Countryside? Politics of Water Contestation in the Mumbai-Thane Region of India

This dissertation comprises three papers that focus on the interplay of formal and informal institutional processes in the sharing of water between the Mumbai Metropolitan region and an agricultural area to its north and east in Thane district. The first paper focuses on the interests and motivations that influence the everyday practices of the canal bureaucracy in the Surya project in Dahanu. This paper is largely a critique of the application of rational choice theory to analyzing bureaucratic corruption in a literature in development studies that was pioneered by Robert Wade. Using an ethnographic narrative style, the paper seeks to provide an account of bureaucratic corruption by focusing on tensions within the local Irrigation Department over bribes and transfers. The poor maintenance of the canal system by engineers in Dahanu and the consequent wastage of water are highlighted as providing a rationale and justification for diversion of water to the Mumbai Metropolitan Region. The second paper traces the historical evolution of institutional practices and local water policy in the Tansa-Vaitarna (T-V) water district, a major source of water for Greater Mumbai and others towns in the Mumbai metropolitan region. It analyzes the failure of collective action in the water district over local water needs and identifies prior appropriation and the fragmentation of metropolitan water governance as the two major factors that are constraints in meeting the water needs of the rural population in the T-V water district. The third paper focuses on the experiences of farmers with water scarcity and dispossession from land on a canal system in two villages in Dahanu. The paper uses survey and interview data from interviews with farmers to understand how water scarcity is manufactured on the canal minor system and discourses of efficiency, abundance and waste are deployed by wealthy commercial farmers and local elites to deprive small and marginal tribal farmers from water
