ORINOCO REPORT CARD RIVER BASIN 2016 COLOMBIA

The 2016 Orinoco River Basin Report Card evaluates the health of various sub-basins in Colombia, assigning an overall grade of B- (63%). The assessment reveals a strong west-east gradient, with Andean headwaters in the west facing severe degradation from mining, oil and gas, and agro-industry, while eastern sub-basins like the Matavén (Grade A) remain more intact. Key concerns include poor human nutrition in the Inírida basin and significant data gaps in water quality monitoring and biodiversity surveys across several tributaries.

• The Colombian Orinoco River Basin received an overall health grade of B- (63%), with scores varying by category; Ecosystems & Landscapes and Water performed better than Biodiversity, People & Culture, and Management & Governance.
• A distinct west-east health gradient exists within the basin, where development pressures in the west lead to poorer water quality and landscape changes. The Upper Meta received the lowest grade (D+, 37%), while the Matavén received the highest (A, 87%).
• The Inírida sub-basin recorded the lowest score for human nutrition in the entire Orinoco River Basin at 31%, which is attributed in part to lower fish richness compared to Andean sub-basins.
• Extractive industries and agro-industry are primary drivers of degradation. Specific pressures include 942 mining concessions as of 2014, 8 million hectares under oil and gas exploration, and 320,829 hectares of agro-industry.
• Significant data gaps hinder comprehensive basin management, specifically a lack of IDEAM National Network Monitoring water quality sites in the Arauca, Atabapo, Matavén, Tomo, Tuparro, and Bita rivers, and a lack of biodiversity surveys in the Guaviare, Inírida, Vichada, Matavén, and Arauca basins.
• The report identifies synergies between the basin report card and the 2030 Agenda for Sustainable Development, specifically linking indicators to Goal 2 (Zero Hunger), Goal 6 (Clean Water and Sanitation), Goal 11 (Sustainable Cities), Goal 12 (Responsible Consumption and Production), and Goal 15 (Life on Land).
