Location: Lake Urema, Gorongosa National Park, Mozambique

Study Period: 1984-2023 (Multi-source imagery | Viewer shows 2017-2023 subset)

Data & Methods: Optical remote sensing + SAR imagery, supervised classification, topographic analysis

Key Findings

• ~2 month precipitation response time indicates significant groundwater contribution
• No significant long-term trend despite high interannual variability
• Minimum volumes (2014-2017) coincide with prolonged below-average precipitation
• Groundwater recharge critical for dry season water balance
• Climate change may have limited short-term impact on dry season volumes
