Cuando State of the Basin Report

The Cuando River Basin is a largely pristine transboundary system traversing Angola, Zambia, Namibia, and Botswana. It is characterized by a unique hydrological system where water from the Angolan highlands flows through extensive floodplains, occasionally connecting with the Okavango and Zambezi basins. The region is a critical wildlife corridor within the KAZA TFCA, supporting significant populations of elephants and lions, though it faces threats from poaching, uncontrolled fires, and climate change. Human populations are sparse and primarily rely on subsistence agriculture and the harvesting of natural products, with a growing trend toward urban migration due to the basin's exceptionally poor soil fertility.

• The Cuando River is described as one of the few remaining undisturbed and naturally connected rivers globally, acting as a linear oasis through dry sandy woodlands.
• The basin's hydrology is characterized by a slow flow due to extensive floodplains (5 to 15 km wide), resulting in significant water loss through evapotranspiration.
• Surface water connections between the Cuando, Okavango, and Zambezi basins are temporary and occur only rarely, meaning the Cuando is not a perennial tributary of the Zambezi.
• The basin's soils are exceptionally poor in fertility and water-holding capacity, which limits agricultural productivity and results in low terrestrial biomass.
• Frequent and intense uncontrolled fires, often started by humans for land clearing, are causing a transition from open woodlands to bushy scrubland.
• The basin is a vital part of the Kavango-Zambezi Transfrontier Conservation Area (KAZA TFCA), serving as a critical dispersal corridor for elephants and lions between Angola, Botswana, and Zambia.
• Elephant populations in the region have faced severe declines due to poaching, with a 2015 carcass ratio of 13% in Luengue-Luiana National Park indicating high mortality.
• Climate change projections for the KAZA TFCA indicate a 4.6% decline in total annual precipitation by 2050 and a 3C increase in average annual temperature.
• Human populations in the basin are sparse, totaling approximately 274,330 people, with a notable trend of migration toward urban centers to escape poverty and low agricultural productivity.
