Abstract: | This paper critically examines Brazil’s transbasin diversion experiences and two select, large-scale transbasin projects outside
of Brazil. Rather than simply compare Brazil’s experiences with international cases, the authors explore the historical context
of the projects, focusing on the water resources and environmental regulatory and institutional frameworks in place during
the initial proposals and how they influenced the projects’ development and completion rates. Huge investments, the lengthy
time span between the date of the initial project proposals and the start of construction, the need to garner public and political
support, and more recently, the need to fulfill national and regional environmental laws are major factors underlying heated
public debates about the proposed projects. After a broad discussion about the subject, the authors examine a recently approved
large-scale Brazilian project, the Sao Francisco river transbasin diversion. This river diversion project is considered crucial
to the economic development of Brazil’s semi-arid northeastern region. Despite the fact that this government-funded project
was debated for several decades among the various stakeholders, it was approved under Brazil’s newly formed water resources
regulatory and environmental framework, which enabled improvements in various key technical aspects of the project, and greater
involvement of various key social players. |
