Floodplains form when rivers overflow, depositing sediments on nearby land, creating highly fertile soil. This fertility allows crops to grow abundantly, supporting dense populations and agricultural communities. Examples like the Ganga floodplain in India demonstrate the importance of floodplains in food security and economy. However, floodplains also face seasonal flooding risks, requiring flood control systems to protect residents and farmlands. Their benefits make them essential for sustainable agriculture.
