Understanding the land market is crucial when analyzing the spatial dynamics of cities. Spatial models, which are widely used to describe the growth of cities, are underdeveloped in Africa, due in part to the lack of urban data and/or the difficulty of collecting it. This paper presents a methodology for collecting analyzing land values in major sub-Saharan African cities. Through two case studies in the cities of Lomé and Yaoundé, it describes the implementation of such a methodology for collecting data on land prices and analyzing variations on an urban scale. It offers effective means of developing more accurate models for analyzing the dynamics of the land market.
