Water Management and Agriculture in Semi-Arid Regions

The video discusses the São Francisco River transposition project aimed at addressing water scarcity in Brazil's semi-arid Northeast. Initiated in 1985, the project transfers water to less favored basins, enhancing water security for up to 14 million people. It has transformed agriculture, enabling consistent water supply and reducing dependency on rainfall. The project has spurred economic and social development, with significant improvements in agriculture, commerce, and export. Technological advancements have further boosted productivity, particularly in mango farming, leading to substantial economic benefits.
