Regulating water resources is a critically important yet increasingly complex component of the interaction between ecology and society. Many argue that effective water regulation relies heavily upon the compliance of water users. The relevant literature suggests that, rather than relying on external motivators for individual compliance, e.g., punishments and rewards, it is preferable to focus on internal motivators, including trust in others. Although prior scholarship has resulted in contemporary institutional efforts to increase public trust, these efforts are hindered by a lack of evidence regarding the specific situations in which trust, in its various forms, most effectively increases compliance. We report the results of an experiment designed to...

"Institutional adaptation" for integrated water resources management: An effective strategy for managing Asian river basins AgEcon
Bandaragoda, Don Jayatissa.
In many developing countries, their governments dominate the field of water resources management. Even in “participatory irrigation management” efforts, the governments play a dominant role. As these efforts are rarely based on any internally generated demand from the water users, they usually fail to create viable organizations at the local level. A similar setback can be seen in the more recent institutional reforms in Asia’s water sector, which are promoted by the donor agencies and, national and international development professionals. A survey of experiences in Asian countries shows that no country has successfully completed establishing new water sector policies and laws and river basin organizations, as prescribed. The need to improve current...

ACHIEVING EFFICIENCY AND EQUITY IN IRRIGATION MANAGEMENT: AN OPTIMIZATION MODEL OF THE EL ANGEL WATERSHED, CARCHI, ECUADOR AgEcon
Evans, Elizabeth M.; Lee, David R.; Boisvert, Richard N..
The objective of this paper is to address the problems of inefficiency and inequity in water allocation in the El Angel watershed, located in Ecuador's Sierra region. Water is captured in a high-altitude region of the watershed and distributed downstream to producers in four elevation-defined zones via a system of canals. Upstream and downstream producers face radically different conditions with respect to climate and terrain. A mathematical programming model was created to study the consequences of addressing chronic water scarcity problems in the watershed by shifting water resources between the four zones. The model captures the nature of water use by humans, crops and dual purpose cattle. Its objective function maximizes producer welfare as...

Optimal Allocation of Reservoir Water AgEcon
Debnath, Deepayan; Stoecker, Arthur L.; Boyer, Tracy A.; Sanders, Larry D..
The purpose of this paper is to determine the optimal allocation of reservoir water among consumptive and non-consumptive uses. A non-linear mathematical programming model is developed to optimally allocate Lake Tenkiller water among competing uses that maximize the net social benefit. A mass balance is used to determine the level and volume of water in the lake. This paper examines the effect of water management on lake resources when recreational values are and are not included as control variables in the optimization process. Results show that maintaining the lake level to the ‘normal lake level’ of 632 feet during the summer months generates more recreational benefit rather than reducing the lake level by releasing water for hydro power generation.

Assessing the economic impact of redistributing water within a catchment: A case study of the Musi Catchment in the Krishna Basin in India AgEcon
Davidson, Brian; Hellegers, Petra J.G.J.; Samad, Madar.
The aim in this paper was to present the details of an economic modeling exercise conducted on the Musi Catchment of the Krishna Basin. The model has the unique characteristic of being able to value the water used on individual crops and in different regions. Thus, the individual values of water used to produce different crops, grown over two different seasons and over five very different regions within a catchment, were determined. This is a significant improvement over previous attempts, where a single value of water in a catchment was derived regardless of what it is used for, when it was used and where it used in the catchment. In addition to the agricultural valuation process, some account was made for the other uses of water and how they should be...

Pro-poor intervention strategies in irrigated agriculture: lessons from the Asian experience AgEcon
International Water Management Institute (IWMI).
Irrigated agriculture has contributed greatly to food security in Asia - and irrigation projects present new opportunities for reducing poverty. This requires that projects deliberately tilt towards the poor. Moreover, policymakers, implementers and managers need to adopt an integrated approach when using irrigation as a pro-poor intervention strategy. With the right institutional and technical conditions, an effective incentives structure and proper implementation and management practices, pro-poor irrigation projects can make a significant difference to poverty in the region.

New Zealand freshwater management and agricultural impacts AgEcon
Cullen, Ross; Hughey, Kenneth F.D.; Kerr, Geoffrey N..
In New Zealand, it is increasingly recognised, including by government, that water resource allocation and water quality are issues of national importance. Agriculture is frequently portrayed by public media as a major user of water and a major contributor to worsening water quality. We outline the water management systems in New Zealand, and the use of water by agriculture. Official reports on agriculture’s impact on New Zealand water availability and quality are summarised. We report how the New Zealand public perceive water, its management, and the roles of agriculture in water issues. Data from a nationwide mail survey were analysed to determine how New Zealanders assess the state of New Zealand lakes, rivers and streams, and aquifers, the performance...

The lower Krishna Basin trajectory: relationships between basin development and downstream environmental degradation AgEcon
Venot, Jean-Philippe; Sharma, Bharat R.; Rao, Kamineni V.G.K..
Basin water development and rural dynamics in the Krishna Basin have led to a degradation of downstream ecosystems manifesting itself by salinizing soil and groundwater, increasing pollution, disappearing mangroves and desiccating wetlands. Reversing this evolution requires the formal recognition of the environment as a water user in its own right and the implementation of an environmental water provision. This provision should be based on a two-tier allocation system with assured discharges in the irrigation canals of the delta and to the ocean. This will lead to further commitment of water resources but this is needed to reconcile the social, economic and environmental objectives of a sustainable development. Other measures facilitating integrated...
