This chapter examines the rise of economists as regional development experts with the establishment of new federal institutions in the 1950s, including the Banco do Nordeste do Brasil regional development bank and the Superintendência de Desenvolvimento do Nordeste (SUDENE), the latter modelled on the U.S. Tennessee Valley Authority (TVA). Economic expertise essentially displaced civil engineering for a brief period, in the face of continuing drought crises and DNOCS’s apparent inability to resolve them. The leading figure in the events that unfold is economist Celso Furtado, who led several analyses of the northeast’s development challenges at the request of President Juscelino Kubitschek and became SUDENE’s first director. As a result of rising political tensions in the early 1960s and the association of Furtado and SUDENE’s efforts with land expropriation (a measure promoted by more revolutionary groups like the “Peasant Leagues” of landless farm workers), elite and middle class sectors in Brazil supported a military coup in 1964 to overthrow President João Goulart, which undid much of the progress that Furtado and others had been working toward.
