Key Insights
DRIFT is a structured process that integrates biophysical and socio-economic data to advise on environmental flows in rivers. It involves experts from various disciplines to predict how river ecosystems and subsistence users will be affected by flow changes. The methodology consists of four modules: biophysical, sociological, scenario development, and economic. It aims to provide scenarios for water managers, considering the river ecosystem, subsistence users, and water yield.
