This paper examines the impact of road network conditions on the marketability of agricultural produce in Nigeria, with particular focus on how transportation infrastructure affects agricultural output, income, and food distribution. Drawing on a review of empirical studies conducted across multiple Nigerian states and Sub-Saharan Africa, the paper finds that poor road infrastructure significantly reduces farmers' income, increases post-harvest losses, and constrains market access for rural agricultural producers. The study identifies poor road quality, inadequate transport vehicles, high freight costs, and the absence of feeder roads as key structural impediments to efficient agricultural marketing. The paper recommends targeted government investment in rural road construction and rehabilitation, provision of subsidised transport for farmers, and the establishment of agricultural produce collection centres. These findings carry broader implications for rural development policy and food security strategy in developing economies.
