Governments of the Amazon River Region: A Multi-Nation Overview

The Amazon Basin spans seven South American countries, each with its own democratic government:

• Brazil: Federal presidential republic (largest Amazon share).
• Peru: Presidential republic with unicameral Congress.
• Bolivia: Multi-party presidential republic with bicameral legislature.
• Ecuador: Presidential republic with unicameral National Assembly.
• Colombia: Presidential republic with bicameral Congress.
• Venezuela: Federal presidential republic with unicameral National Assembly.
• Guyana: Parliamentary republic with president and prime minister.

All are electoral democracies with representative institutions, though political stability and governance effectiveness vary. The region lacks a single unified government; instead, cross-border cooperation occurs through treaties and organizations like the Amazon Cooperation Treaty Organization (ACTO).
