A vertically oriented advocacy banner is prominently displayed outdoors in an urban setting of Dhaka, Bangladesh. The banner's upper section features a printed photographic image depicting severe riverbank erosion; a paved road is shown partially collapsed into a wide, murky body of water, with exposed earth and remnants of vegetation on the eroded bank. The far side of the water body shows dense green foliage. The lower section of the banner contains bold red Bengali text on a white background, which translates to "To prevent river erosion, closure (embankment), people's rights." Below this, a circular logo is present, followed by yellow Bengali text on a brown band reading "Sonagazi Association Dhaka." Blurred figures of individuals are visible in the background, indicating a public gathering or display. The ground immediately surrounding the banner is a paved urban surface, with metal barriers visible on the sides, consistent with a public street or square in Dhaka. The banner itself is the primary subject, acting as a communication object for advocacy regarding river erosion, likely in the Sonagazi region, organized by a Dhaka-based association.
