Does data lead to cooperation? Lessons from Water Accounting Plus in the Cauvery basin, India

As the number of studies on remote sensing data for water management and governance increases, few articles reflect on their application in practice. This article shares learnings from the application of Water Accounting Plus (WA+) in a federal river basin in India. WA+ was applied to the Cauvery basin to contribute to solving transboundary water-sharing issues by providing a source of transparent data obtained through reproducible methods. By analysing how WA+ results and methodology were received, we show how data and models are also political and question the assumption that more data automatically lead to more equitable decision-making.
