The objective of this research was to develop and apply a conceptual framework for evaluating the potential of trans-boundary bargaining with respect to water resource sharing. The research accomplished this objective by developing a framework for trans-boundary bargaining, identifying opportunities for application, and illustrating the potential benefits that can be gained thereby. Specifically, we have accomplished the following: - Developed a framework to measure the potential for improving economic efficiency considering issues of political feasibility and sustainability that are crucial in trans-boundary cooperation. - Used both cooperative and non-cooperative game theory to assess feasible coalitions among the parties involved and to model potential bargaining procedures. - Identified empirically alternative schemes of cooperation that both improve upon the economic efficiency of present water usage and appease all of the cooperating parties. - Estimated the potential short-run and long-run affects of water reallocation on the agricultural sector and used this information to understand potential strategies taken by the countries in bargaining processes. - Performed case studies in Israeli-Jordanian relations, the relationship of Israel to the Palestinian Authority, and cooperation on the Chesapeake Bay. - Published or have in process publication of a series of refereed journal articles. - Published a book which first develops the theoretical framework, then presents research results relating to the case studies, and finally draws implications for water cooperation issues generally. Background to the Topic The increase in water scarcity and decline in water quality that has resulted from increased agricultural, industrial, and urban demands raises questions regarding profitability of the agricultural sector under its present structure. The lack of efficient management has been underscored recently by consecutive years of drought in Israel and increased needs to clean up the Chesapeake Bay. Since agriculture in the Middle East (Chesapeake Bay) is both the main water user (polluter) and the low-value user (polluter), a reallocation of water use (pollution rights) away from agriculture is likely with further industrial and urban growth. Furthermore, the trans-boundary nature of water resources in the case of the Middle East and the Chesapeake Bay contributes to increased conflicts over the use of the resources and therefore requires a political economic approach. Major Conclusions, Solutions, Achievements and Implications Using game theory tools, we critically identify obstacles to cooperation. We identify potential gains from coordination on trans-boundary water policies and projects. We identify the conditions under which partial (versus grand) coalitions dominate in solving water quality disputes among riparian countries. We identify conditions under which linking water issues to unrelated disputes achieves gains in trans-boundary negotiations. We show that gains are likely only when unrelated issues satisfy certain characteristics. We find conditions for efficient water markets under price-determined and quantity-determined markets. We find water recycling and adoption of new technologies such as desalination can be part of the solution for alleviating water shortages locally and regionally but that timing is likely to be different than anticipated. These results have been disseminated through a wide variety of publications and oral presentations as well as through interaction with policymakers in both countries.

This trial aimed to evaluate effects of stocking densities of 1-5 fish/m2 on growth performance, survival rate and economic efficiency of Asian seabass (Lates calcarifer) in earthen ponds. Fish with an initial length of 90.7 ± 0.1 mm and weight of 20.8 ± 0.1 g/fish and ponds with 600 m2 each and 1.5 m depth were used for this study. Experiment was designed with three treatments, including different stocking densities of 1, 3 and 5 fish/m2. The fish was fed with pellete feed containing 43 - 44% crude protein. Water quality parameters including temperature, dissolved oxygen, pH, salinity, transparency and ammonia concentration were measured once a week. Fish were sampled every 30-day intervals for length and weight measurement then for their growth estimation. Costs were recorded for economic efficiency estimation. Results showed that the water quality parameters were in suitable ranges for growth and development of Asian seabass. The final average length and weight of density 1 fish/m2 was significantly higher than those at 3 and 5 fish/m2 (P < 0.05). However, there was no significant difference on the fish growth in terms of daily length and weight gain, as well as survival rate and feed conversion ratio between different stocking densities. Asian seabass culture at 3 and 5 fish/m2 resulted in a higher profit compared to at 1 fish/m2. The highest economic efficiency in terms of area pond was showed at 5 fish/m2 treatment.

Because of the decline of the Ogallala Aquifer, water districts, regional water managers, and state water officers are becoming increasingly interested in conservation policies. This study evaluates both short-term and long-term water rights buyout policies. This research develops dynamic production functions for the major crops in the Texas Panhandle. The production functions are incorporated into optimal temporal allocation models that project annual producer behavior, crop choices, water use, and aquifer declines over 60 years. Results suggest that long-term buyouts may be more economically efficient than short-term buyouts.

Establishing water rights is an appealing measure, which conveys a sense of orderliness and rationality that contrasts with a situation of assumed wastage, environmental degradation and con.icts. Transferable entitlements increase economic efficiency, while providing a compensation mechanism. The paper distinguishes between formal rights de.ned through a bureaucratic process and flexible allocation rules designed through a gradual and continuous process of negotiation. It investigates the prerequisites, advantages and drawbacks of these two kinds of water rights, and examines how they apply to the specific natural and historical conditions of Sri Lanka. It concludes by showing that policy models must be tailored to the local situation and be based on what is feasible rather than on what is considered desirable.

Improvements in the quality of the waterways of England and Wales are often argued to be attributable to the cooperation between Authorities and dischargers, and that such cooperation could be jeopardized if prosecution of dischargers became more frequent. This paper, by using an economic model of law enforcement, tests whether there is any evidence of an association between enforcement policies and changes in water quality. It demonstrates the difficulty of examining problems of enforcement in isolation and then outlines a new procedure, both for allocating and for enforcing consents, designed to improve economic efficiency whilst maintaining traditional British cooperation.

As reflection of property rights in the field of water resources, water rights is the right to use water resources in a certain period of time based on water quantity and water quality. Aimed at solving the issue of basin initial water right allocation in China, on the basis of the pre-research of index system of basin initial water rights allocation system, as well as the complexity and differences of the allocation system, the index system of basin initial water rights allocation system in this paper is comprehensively designed, and the index framework divided into three layers of target, criteria and index angles is established.
