The image depicts an active construction site in Karsana 2, Nigeria, under a hazy sky. Six adult males are present on a dry, dusty plot of land. In the mid-ground, two men are actively engaged with a pile of sand and cement mixture; one, wearing a light-colored shirt, uses a hoe to mix the material, while another, in a yellow shirt and blue cap, stands nearby with a shovel. A black bucket rests on the ground next to the mixture. The primary focus of the site is the construction of a building foundation or lower walls using grey hollow core concrete blocks. These blocks are laid out in linear and perpendicular formations across the ground, forming the perimeter and internal divisions of a structure. Some blocks are stacked vertically, creating columns. Steel reinforcing bars (rebar) protrude upwards from inside several of the laid and stacked blocks, indicating future concrete pouring. In the background, a man wearing a white head covering is seated on a concrete block, observing the work. Three other men stand behind him, also observing. The surrounding environment consists of dense, tall green vegetation and scattered trees, suggesting an undeveloped or semi-rural area transitioning into built space. Shadows are cast by the people and blocks, indicating direct sunlight from a high angle.
