Land governance and lack of an appropriate cadastral management system The case study of land rights regularization in informal settlement using geospatial data collected with uav in yaoundé, cameroon

Abstract

The Unmanned Aerial vehicle (UAV), also known as drone, is a photogrammetric platform used as alternative solution to overcome the limits of traditional surveying methods. This study aims to analyze a small study area in Yaoundé, Cameroun using high resolution geospatial data of UAV and STDM for recording of land right in informal settlement. The study shows that, the high-resolution aerial images of UAV based on orthophotos can be used to solve problems related to land governance and the regularization of tenure rights through participatory boundary delineation and mapping approach. We noticed many problems related to the land ownership illustrated by contradictions between the municipal administration data and the results of our investigations. The CUY publishes that, out of 16.70% of the people with land certificates, 9% of the potential owners confirmed their rights, while the land map issued by the council is showing three. A well-established municipal housing estate would never have been transformed into an informal settlement with the existence of its own computerize land management system. The advantages of UAVs (large and rapid aerial georeferenced data collection in less time, with high accuracy at low cost) make it possible to develop such a system in order to secure the land rights of all, particularly for the poor living in informal settlements.
