Social aspects of water management during the Maha season 1985/86 in Dewahuwa and Mahaweli H-2 Block 305: precept and practice AgEcon
Bulankulame, Senarath.
The International Irrigation Management Institute (IIMI) began research projects in Dewahuwa Tank and Mahaweli 11-2 during the Yala season (May-Aug.) of 1985. The research focussed initially on agricultural economics (e.g., farmers' use of agricultural inputs and returns from different crops) and on irrigation engineering (water distribution and flow rates). In the second season (Maha 1985/86) of research a social science component was added to address issues of farmers' management decisions and the institutional arrangements by which farmers and agency officials operate and maintain the irrigation works. This report summarizes the research results of the social science component for the Maha season, from October 1985 to April 1986.

Essais de decontamination des huitres Crassostrea gigas en bassin par renouvellement et circulation de l''eau ArchiMer
Faury, Nicole; Masson, Daniel; Ratiskol, Jacqueline.
The germs decreasing of artificially contaminated oysters Crassostrea gigas has been studied in experimental tanks similar to a shellfish depuration plant, without any chemical or physical water treatment. The oyster were treated by three different water management pattern, compared to a control tank and the germs decreasing studied by MPN method of fecal Coliforms and Streptococus. As a result: 1) it appaears somewhat difficult to conclude in this first attempt about the most efficient treatment. 2) the most important factor in shellfish depuration working is obviously the physiological activity (and stage) of the animals.

Locally managed irrigation systems: essential tasks and implications for assistance, management transfer and turnover programs AgEcon
Yoder, Robert.
This monograph examines the construction, operation and maintenance tasks that shape the nature of locally managed irrigation systems. The objective of the book is to identify relevant experiences and lessons for staff who are responsible for working with locally managed systems in three types of programs: direct assistance to existing locally managed irrigation systems, turnover of public owned systems to local management, and transfer of partial management to farmer groups within larger systems that remain publicly controlled.
Tipo: Book Palavras-chave: Irrigation management; Irrigation systems; Irrigation scheduling; Privatization; Farmer participation; Water management; Water rights; Water allocation; Resource management; Organizational dynamics; Conflict; Communication; Training; Farm Management; Institutional and Behavioral Economics.

An Approach to Sustainable Water Management Using Natural Resource Accounts: the Use of Water, the Economic Value of Water, and Implications for Policy OceanDocs
Lange, G.M..
A Natural Resource Accounting project is currently underway to document the status of the nation’s resources and their current economic use. Accounts for water constitute a major component of the Natural Resource Accounts (NRA) since water is the limiting resource for economic development in Namibia, as it is for much of Southern Africa. The NRA include both stock and use accounts for water, as well as related environmental statistics. In order to design development strategies that are sustainable over the long run, it is essential to know the full value of this scarce resource. This is especially important for a resource like water which is used throughout the economy and must be managed to achieve sometimes conflicting economic, social, and political...

Accounting for water use and productivity AgEcon
Molden, David J..
This paper presents a conceptual framework for water accounting and provides generic terminologies and procedures to describe the status of water resource use and consequences of water resources related actions. The framework applies to water resource use at three levels of analysis: a use level such as an irrigated field or household, a service level such as an irrigation or water supply system, and a water basin level that may include several uses. Water accounting terminology and performance indicators are developed and presented with examples at all the three levels. Concepts and terminologies presented are developed to be supportive in a number of activities including: identification of opportunities for water savings and increasing water...

Impact assessment of rehabilitation intervention in the Gal Oya Left Bank AgEcon
Amarasinghe, Upali A.; Sakthivadivel, Ramasamy; Murray-Rust, Hammond.
Assesses the impact of rehabilitation interventions on irrigation system performance using time series analysis. The study demonstrates that with proper impact specification and model identification, the nature and magnitude of the impacts of different interventions can be separated from the effects of simultaneous changes in dominant exogenous factors.

Technology Transfer from Publicly Funded Research for Improved Water Management: Analysis and Australian Examples AgEcon
Tisdell, Clement A..
Considerable public funding is provided for research and development intended to improve the management and use of shared natural resources, such as water. In Australia the Land and Water Research and Development Corporation (LWRRDC) and Environment Australia are significant providers of such funds. These providers tend to judge the value of R & D projects supported by them on the basis of whether or not significant technology transfer and adoption takes place. Researchers involved in these projects and expected to be the prime movers of such transfer. However, it seems that research funders have been guided by over simplified models of processes of technology transfer and by false analogies with the transfer of industrial technology. There has...

Productivity and performance of irrigated wheat farms across canal commands in the Lower Indus Basin AgEcon
Hussain, Intizar; Marikar, Fuard; Jehangir, Waqar Ahmed.
A study of the enormous differences in agricultural productivity that exist across farms and regions in Pakistan, where, for example, recent farm-level data from Sindh, indicates that irrigated wheat output per hectare varies from 0.5 to 5.4 tons across farms. Looks at the central goal of agricultural policy in the country, viz. improving and sustaining productivity, narrowing the existing productivity gaps, and enhancing resource use efficiencies to meet food requirements of a rapidly growing population.
