Bioregion
Caatinga
Also known as: Sertão, Brazilian semi-arid, Caatinga biome
The only major biome unique to Brazil — 850,000 km² of seasonally dry tropical forest and thorn scrub in the country's semi-arid Northeast. Its name (Tupi for 'white forest') describes how the vegetation drops its leaves and silvers in the long dry season, then explodes green when the rains return. Home to ~28 million people, the great majority smallholder farmers, herders, and beekeepers whose food systems are adapted to drought; cradle of agroecological resilience movements like ASA's million-cisterns program and the Articulação do Semiárido.
Why this entry
The Caatinga anchors all 0mn1.one listings drawn from Northeastern Brazilian states. It enters the wiki because the Brazilian organic registry places thousands of certified organic producers inside the semi-arid Northeast — bee-keepers, sisal weavers, cashew and umbu cooperatives, agroforestry collectives, family-farm associations — all working with rather than against the dry season.
What’s distinctive
A semi-arid biome with ~500–800 mm of rain falling almost entirely in a 3–4 month window, and a dry season that can last 7–9 months — sometimes longer, in the multi-year droughts that periodically cycle through the region. The vegetation responds with deciduous trees, thorny legumes, succulents (cacti, bromeliads), and a high rate of endemism — many plant and animal species occur nowhere else on Earth.
The Caatinga is also where Brazilian agroecology learned its hardest lessons: how to grow food in a place that rejects most imported farming systems. ASA Brasil (Articulação do Semiárido), founded in 1999, organized the construction of over a million rooftop-cistern household water systems and tens of thousands of agroecological backyards (quintais produtivos). Native species — umbu, licuri, mandacaru, juazeiro, faveleira — return to gardens as people relearn what their grandparents grew.
Why it matters to the mission
Drylands cover 41% of Earth’s surface and house 2.3 billion people. The Caatinga is the densest concentration of accumulated knowledge in the Americas for how to feed a population on rainfall measured in single digits of inches. Its smallholder cooperatives — many CNPO-certified — are not curiosities; they are the working library for what every other dryland on Earth is about to face.
