Overview

Modeling assesses projected streamflow response in the lower Okavango River Basin, indicating urgent management needs.

Key Points

  • The study aims to evaluate the impact of climate and land use changes on streamflow in the lower Okavango River Basin.
  • Utilized the SWAT+ hydrological model to simulate future streamflow changes.
  • Forced the model with downscaled climate projections and land use scenarios.
  • Analyzed streamflow and water yield across three future periods up to 2100.
  • Projected decrease in precipitation by 5-20% by 2100, leading to up to 60% reduction in streamflow.
  • Dry season flows are expected to nearly cease.
  • Cropland will expand to over 65% of the basin, significantly reducing natural wetlands.
