This outdoor photograph captures a severely polluted waterway and an informal settlement on a bright day in Nairobi, Kenya, consistent with areas along the Nairobi River. In the foreground, a dark, turbid body of water, heavily contaminated with floating refuse including plastic bags, bottles, and general debris, flows from the center-left towards the lower right. Dense green vegetation, including aquatic plants, grows profusely within and along the banks of this waterway. Two prominent concrete structures, remnants of a collapsed or dismantled bridge, are visible: a cylindrical concrete pillar stands partially submerged on the left, and a cluster of broken, angular concrete blocks, some with visible blue coloration, lie partially submerged and overgrown with vegetation on the right. The midground features a steep, eroded embankment rising from the waterway, covered extensively with discarded waste and sparse, dry vegetation. This hillside supports a dense informal settlement composed of numerous makeshift dwellings constructed from corrugated metal sheets, tarpaulins, fabric, and other scavenged materials. In the background, the informal settlement extends further up the hillside, interspersed with scattered trees, including some with bare branches. On the far left, taller, more permanent buildings and a slender telecommunications tower are visible, suggesting the proximity of more formal urban development. The sky is clear and bright blue with scattered white cumulus clouds, and a strong lens flare from the sun is present in the upper left quadrant. No individuals are discernible in the scene.
