Land Use in the Brazilian Highlands: Agriculture, Mining, Cities, and Conservation
The Brazilian Highlands (Planalto Brasileiro) cover roughly 4.5 million km²—over half of Brazil's land area—spanning the states of Minas Gerais, São Paulo, Goiás, Mato Grosso, Bahia, Paraná, Santa Catarina, Rio Grande do Sul, and the Federal District. This vast, ancient plateau (average elevation 500–1,500 m) is the country's economic engine. Here's how the land is used.
1. Agriculture: The Global Breadbasket
The highlands' deep, well-drained Oxisols (Latossolos) and Alfisols, combined with distinct wet/dry seasons, make them ideal for mechanized farming.
| Crop | Key States | Brazil's Global Rank |
|---|
| Soybeans | Mato Grosso, Paraná, RS, GO | #1 exporter (50%+ world trade) |
| Coffee | Minas Gerais, Espírito Santo, SP | #1 producer/exporter (35%+) |
| Corn (maize) | PR, RS, MG, GO, MT (safrinha) | #3 producer, #2 exporter |
| Sugarcane | SP (traditional), GO, MT, MS (expansion) | #1 producer (sugar & ethanol) |
| Cotton | BA, MT, GO, PI | #4 producer, #2 exporter |
| Orange juice | SP (Citrus Belt) | #1 (70%+ global export) |
Trend: Crop-livestock-forest integration (ILPF) growing—rotating soy/corn with pasture and eucalyptus to restore soil.
2. Livestock: The World's Largest Commercial Herd
- ~230 million cattle (2023) — mostly Nellore (Zebu) adapted to tropics.
- Extensive pasture: ~160M ha planted pasture (Brachiaria grasses), concentrated in Cerrado (savanna) and Pantanal fringes.
- Beef exports: #1 globally (~2.5M tonnes/year). China, USA, EU main markets.
- Dairy: Intensive systems in MG, SP, PR, RS, SC — ~35B liters/year.
3. Mining: Mineral Powerhouse
The highlands host world-class deposits in Precambrian shields (Amazon, São Francisco, Paraná cratons):
| Mineral | Key Districts | Global Significance |
|---|
| Iron ore | Quadrilátero Ferrífero (MG), Carajás (PA - edge) | #2 producer (Vale), #1 exporter |
| Gold | MG (Morro Velho), GO, MT, PA | Top 10 producer |
| Niobium | Araxá (MG), Catalão (GO) | #1 world (90%+) — CBMM |
| Bauxite | Paragominas (PA), Trombetas (PA) | #3 producer |
| Manganese | Azul (PA), Urucum (MS) | Top 5 |
| Nickel, Copper, Rare Earths | GO, BA, CE, RN | Emerging |
4. Forestry: Plantations & Native Forests
- Eucalyptus / Pine plantations: ~10M ha (MG, SP, PR, SC, RS) — pulp, paper, charcoal (steel), lumber. Brazil = #1 pulp exporter (Suzano, Klabin, Cenibra).
- Atlantic Forest (Mata Atlântica): Biodiversity hotspot, ~12% remaining. Legal reserves (20% rural property) + restoration commitments.
- Cerrado: Savanna woodland — 50% converted. Soy/cattle frontier. Legal reserve 20–35%.
- Amazon fringe: Deforestation pressure on highland margins (MT, PA, RO).
5. Hydroelectric Power: The Battery of Brazil
- ~65% of Brazil's electricity from hydro.
- Major highland dams: Itaipu (Paraná River, #2 world), Belo Monte (Xingu), Tucuruí (Tocantins), Furnas (Grande), São Simão (Paranaíba), Jupiá / Porto Primavera (Paraná).
- Reservoirs provide irrigation, navigation, recreation — but displace communities, emit methane, trap sediment.
6. Urban Settlements: Megacities on the Plateau
| Metro Area | Population (2022) | Economic Role |
|---|
| São Paulo | 22.4M | Financial/industrial capital, #1 GDP city in SH |
| Belo Horizonte | 6.1M | Mining, tech, fashion, gastronomy |
| Curitiba | 3.8M | Urban planning model, auto/tech hub |
| Brasília (Federal District) | 4.8M | Capital, government, services |
| Goiânia | 2.7M | Agribusiness, health, logistics |
| Campinas | 3.3M | Tech (Unicamp), pharma, logistics |
7. Conservation & Conflicts
- Protected areas: ~18% of highlands (parks, reserves, APAs). Key: Serra da Canastra, Chapada dos Veadeiros, Itatiaia, Iguaçu.
- Water security: Highlands = source of 8 of 12 major hydrographic regions. Deforestation → reduced recharge, siltation.
- Land conflict: Indigenous (Guarani Kaiowá, Xavante), Quilombola, campesinos vs. agribusiness/mining.
- Climate risk: Cerrado drying; longer dry seasons; fire frequency up.
Bottom Line
The Brazilian Highlands are a working landscape—intensively farmed, mined, urbanized, and dammed—yet still harboring globally critical biodiversity and water resources. The central challenge of the 21st century: intensifying production on existing cleared land while restoring corridors and protecting the last native vegetation.
