Guyana's Three Major Industries: Bauxite, Rice, Sugar

Historically, Guyana's economy rested on three export pillars—all primary commodities, all foreign-exchange earners, all now challenged by oil.

1. Bauxite & Alumina

• Discovered 1910s. Commercial 1917 (DEMBA/Alcoa).
• Major deposits: Linden (Region 10), Aroaima, Kwakwani.
• Peak: 3M+ tonnes/yr (1970s). Current: ~1.5M tonnes (RUSAL/Bosai, First Bauxite).
• Value: Calcined bauxite (refractory grade) commands premium. Alumina plant (Mackenzie) closed 1982; talk of revival.

2. Rice

• Introduced 18th c. by enslaved Africans. Expanded post-1838 (indentured Indian labor).
• Coastal plain (Regions 2–6). Two crops/yr (spring, autumn).
• Production: ~500K–600K tonnes paddy/yr. Exports: ~400K tonnes (CARICOM, Venezuela, EU, US).
• GRPA coordinates. Millers (private + GNCWS) process. Challenges: drainage, salinity, variety improvement, logistics.

3. Sugar

• Colonial engine (1650s–1970s). Nationalized 1976 (GuySuCo).
• Estates: Skeldon, Albion, Rose Hall, Blairmont, Enmore, Wales.
• Collapse: 300K tonnes (1970s) → <50K tonnes (2022). Closures (Wales, Rose Hall, Skeldon). Causes: aging factories, labor costs, price drops, mismanagement, sea-level rise.
• Transition: Diversification (cassava, corn, cattle), land redistribution, closure packages.

The New Fourth Pillar: Oil

Since 2020 (Liza field, ExxonMobil/Hess/CNOOC), oil dominates—>60% GDP, >80% exports. The "big three" now share stage with a behemoth. Transition management is the national question.
