The term "sertão" refers to a vast, semi-arid region in northeastern Brazil. It is characterized by its dry climate, sparse vegetation, and unique ecosystems. The sertão is known for its rugged terrain, including hills and plateaus, and experiences long periods of drought, which significantly impacts agriculture and water availability. Despite its harsh conditions, the sertão is home to diverse communities and rich cultural traditions. The region is often associated with Brazilian folklore, music, and literature, reflecting the resilience of its inhabitants. Many people in the sertão rely on subsistence farming and livestock raising to sustain their livelihoods.
