Ernest Uwayezu successfully defends doctoral dissertation.

Unfortunately given the Corona crisis the defence could not take place in presence but it had to be organised via an online session. Nevertheless, this worked out effectively. Examiners were Prof. de Vries (as supervisor), Prof. Wunderlich (Chairman), Prof. Voß (Leibniz University Hannover) and Prof. Zevenbergen (University Twente, Netherlands).The dissertation of Ernest Uwayezu is publication-based (cumulative), containing 5 publications which were brought together through an additional introductory and conclusion section.The dissertation assesses the degree to which the promotion of spatial justice relates to and enforces the promotion of land tenure security.This evaluation is relevant because the two types of development objectives originate from different domains and logics. With a thorough evaluation, based on both documented evidence and empirical data it is possible where the logics of both reinforce and where they contradict, and what the outcomes are, especially for affordable housing schemes and the permissions to occupy land, in such cases. The relevance of the dissertation lies in the fact that both a new conceptual framework for assessment has been derived and in the fact that currently applied land intervention projects are practically evaluated and assessed in a specific context of Kigali.
