Bangladesh is widely known as one of the most vulnerable countries to climate change effects with coastal areas prone to intense climatic extreme events. The climate-induced extreme events such as sea level rise, floods, cyclones, storm surges, and salinity intrusion greatly affect water supply system in that region. Rainwater Harvesting (RH) from the rooftops can be a good alternative source of safe water as the country receives ample (on an average 2400mm) rainfall per year that could reduce water crisis problem in the coastal region. Water demand and supply equation can be a measurement tool to measure rainwater availability to meet water demand over the whole year. But utilizing rainwater needs government support regarding the RH policy for sustainable use of rainwater, creating awareness, RH promotion for letting people know about its advantages, disadvantages and challenges, technical support for good maintenance and operation for rainwater harvesting system and finance for settings up the infrastructure. This paper examines the possibility of rainwater harvesting for reducing water poverty in coastal Bangladesh. The study found that rainwater harvesting can supplement the existing water supply systems and reduce the water poverty in the coastal region of Bangladesh.
