On February 05, 2026, Anugraha Das will present her internship results on ” Stream flow assessment and Irrigation demand in Central Asia (Aral Sea )” at 12:00 in seminar room 3, John-Skilton-Str. 4a.
From the abstract: This presentation assesses streamflow dynamics and irrigation water demand in the Aral Sea basin, Central Asia, with a focus on understanding long-term changes in agricultural water use and their downstream impacts. The study examines how irrigation regimes have evolved over time, whether current downstream irrigation demand exceeds available river discharge, and if sufficient water reaches natural ecosystems. Using a spatio-temporal analysis framework, critical months of water stress are identified to evaluate mismatches between water availability and demand. The results contribute to understanding the role of upstream agricultural water diversion in the Aral Sea crisis and provide insights into sustainability challenges for river flow management and ecosystem preservation in the region.
