Casa Nova

Casa Nova is a municipality situated in the Bahia state within the semi-arid northeast region of Brazil. The settlement was established in 1879 along the São Francisco River, initially sustaining its early development through the nineteenth-century commercialization of locally harvested salt.

A major historical turning point occurred in the 1970s when the construction of the Sobradinho dam and hydroelectric project downstream caused the original city, known as Casa Nova Velha, to be permanently flooded by the expanding Sobradinho Reservoir. To counter this inundation, the entire population and municipal infrastructure were relocated between 1976 and 1977 to higher ground north of the original site, positioned directly along the BR-235 roadway.

In the decades following this forced relocation, researchers and academicians have frequently studied the resulting socioeconomic challenges to formulate lessons for future hydroelectric developments. Prior to this flooding, the municipality experienced other turbulent periods, including the Pau de Colher movement and the subsequent 1938 Pau De Colher Massacre near the border with the state of Piauí.

The Historical Turning Point of Casa Nova

Casa Nova is a Brazilian municipality located in the state of Bahia within the semi-arid northeast region of the country, known as the Nordeste. Founded in 1879 along the historical alignment of the São Francisco River, the city initially grew around the commercialization of nineteenth-century salt deposits and river-boat trade.

A profound historical turning point occurred in the 1970s when the construction of the Sobradinho dam and hydroelectric project downstream forced the flooding of the original city, now called Casa Nova Velha or Old Casa Nova. Between 1976 and 1977, the entire population and municipal infrastructure were relocated to higher ground north of the original site along the BR-235 roadway.

This forced migration profoundly reshaped the municipality, which spans 9,648.94 square kilometers within the Caatinga semiarid biome. In the decades following the relocation, the socioeconomic challenges of the displacement have been extensively studied by academicians to derive lessons for future hydroelectric developments globally. Today, the relocated municipality supports an agricultural and livestock economy, irrigation-enabled vineyards producing millions of bottles of wine annually through the Grupo Miolo Terranova winery, and fresh water beach tourism at the Dunas do Velho Chico on the Sobradinho Reservoir.
