Book excerpt: The equitable sharing of benefits in transboundary river basins is necessary to solve disputes among riparian countries and to reach a consensus on basin-wide development and management activities. Benefit-sharing arrangements must be collaboratively developed to be perceived not only as efficient, but also as equitable, and to be considered acceptable to all riparian countries. The current literature mainly describes what is meant by the term benefit sharing, in the context of transboundary river basins, and discusses this from a conceptual point of view. Practical, institutional arrangements that ensure maximum economic welfare, as well as collaboratively developed methods for encouraging the equitable sharing of benefits, are, however, not provided. The overall objective of this PhD project was to develop an institutional arrangement, that includes both water allocation policies and benefit-sharing mechanisms, to improve the sustainability of managing transboundary water resources and to encourage cooperation between riparian states. The methodology extends the traditional approach, which is based on highly constrained allocation policies, that merely complement existing management institutions, by efficiently allocating water resources and then equitably sharing the benefits derived from water use. This thesis details the institutional arrangement developed and, through three separate activities, the main components of the arrangement are analyzed. A river basin authority (RBA) is the operator of a market-based system, in which economically efficient allocation policies are identified and imposed on water users, who are charged for the water allocated to them. These charges are collected and redistributed, via a sharing rule specific to the river basin, to ensure equity among the water users. The Eastern Nile River Basin is used as the case study to illustrate the approach. There are important hydropower and agricultural sectors spread across three countries (Egypt, Sudan and Ethiopia), and there is a long history of non-cooperation in this river basin. Current water allocation is based on colonial era bilateral agreements that designate Egypt and Sudan as the only beneficiaries of the Nile waters. Future cooperation is imperative, in this basin, to take advantage of hydropower potential in Ethiopia, and agriculture potential in Sudan, as well as to mitigate, as much as possible, the effects of climate change in the near future. Results reveal that the cooperative management of the Eastern Nile River Basin and its infrastructure would significantly increase the basin-wide economic benefits and lead to more efficient water allocation. The institutional arrangement ensures that water is withdrawn where it has the greatest value (efficient water allocation is established) and that upstream investments in low productivity projects are discouraged. The highest level of cooperation is effectuated through a supranational institution and all parties must agree on the definition of fairness in the sharing of benefits.The imposition of specific axioms, based on this agreedupon vision of fairness results in a unique solution for the distribution of economic benefits. A sharing rule developed with stakeholder input may be more acceptable because the definition of the rule is not in question, as would be the case if existing rules were applied with their inherent definitions of equity. Finally, overall results show that achieving trade-offs between efficiency and equity can occur when these two principles of water allocation are coupled to first maximize the benefits from water use and then reallocate these in an equitable manner.
