The floods have disrupted the lives of nearly five million people, affecting homes, livelihoods, and essential services. Low-lying areas and floodplains have been particularly vulnerable due to Bihar's flat topography and sediment-rich rivers. Roads, drinking water sources, and agricultural fields have been inundated, isolating villages and impacting access to healthcare, education, and markets. The high population density in flood-prone areas has magnified the humanitarian impact, with many families facing displacement, loss of crops, and contamination of water supplies.
