Spatial and seasonal variation in rainfall Floods Droughts Agricultural land affected by: - Pollution / poor water quality - Flooding - Loss of nutrients due to dams - Drought Population Displacement: - Floods Population Displacement: - Drought Clearing of land for agriculture: - Erosion - Increased sediment runoff - Increased flooding Sediment runoff from floods Population Increase: - Increase in pollution - Increased demand for energy Manufacturing: - Pollutants - Increased energy demands Marine Life: - Reduction in health & quantity - Fishing industry reduction 1998 Flood: - Significant loss of life - Millions homeless - Long term physical and economical damage Dams / Energy Production: - Pollutants – Increase CO2 / Methane - Downstream sediment issues - Upstream flooding issues - Population displacement Shipping: - Increased demand due to manufacturing - Pollutants deposited into river system - Difficult navigation to lower reaches Sediment Issues: - Sediment flow interrupted by dams - Sediment build up reduces flood storage capacity - Nutrients do not get to agricultural land YANGTZE RIVER BASIN CONCEPTUAL MODEL - PART 1 ASSESSMENT
