WRI has conducted in-depth studies in a number of key river basins around the world. These basin studies have helped develop, refine, and validate the Water Risk Framework at the core of the Aqueduct global maps, and uncovered a wealth of knowledge about the unique conditions in critical river basins around the world.

The Orange-Senqu River basin is located in southern Africa, encompassing all of Lesotho, half of South Africa, a quarter of Namibia, and southwestern Botswana. Lesotho and South Africa supply over 95% of the water in the basin. The basin is highly engineered, with numerous dams and complex transfer schemes used to manage and distribute water between primarily industrial users in the headwaters, and downstream agriculture. Multiple initiatives are being carried out by local and international governments to insure sustainable and equitable water resources management across the basin.

The Orange-Senqu River Basin Study focuses on the specific characteristics of the indicator data and calculation in the Orange-Senqu River Basin. The data used for the study were developed in consultation with local experts and are publicly available. The details of the data, sources, and methodology are provided in the Orange-Senqu River Basin Study metadata document.
