Impacts Water

During the monsoons, Bangladesh receives high amounts of rainfall and peak flows from the Padma, Brahmaputra, and Meghna rivers cause floods that can affect more than 55 percent of the total land area. In spite of the high amount of rainfall, there is lack of adequate infrastructure and water distribution system. Inadequate planning of flood control, drainage, and irrigation interventions is thought to have led to worsened off-site flooding, poor drainage of wetlands, and increased water logging and salinization. Bangladesh is also especially susceptible to increasing salinity of the groundwater as well as surface water resources, especially along the coast, due to increases in sea level as a direct impact of global warming. Conflict and competition between various water using sectors also lead to water scarcity during the dry seasons. The country also struggles with many water-borne diseases during the flood season.
