INTERBASIN TRANSFER‐THE INTERNATIONAL DIMENSION1

Abstract

ABSTRACT. A number of interbasin transfers are technically possible on an international scale but extremely few have been developed or are in prospect of early development. The institutional constraints are strong and nationalistic reactions to proposals which strongly favor either one of the nations involved have contributed to delays in development.Many of the more striking illustrations of the problems and opportunities relating to international transfers are present in the proposals for Canadian water export to the United States. Some have antagonized Canadians and made further negotiation difficult but phased and sequential transfers are possible and some could complement Canadian development. An important early phase might be the provision of guarantees for replacement supplies in option agreements that would free current surpluses within the United States for more intensive use. It should no longer be assumed that engineering development will provide adequate benefits for the source region. Allowances for opportunity costs, environmental improvements and some profit on sales appear to be needed for upstream areas if transfers are to be made. Many hazards are present but these can be more than offset by the opportunities if both countries strive for mutual benefit through rational study and continuing negotiation.
