Abstract This work guides through the process of introduction of the Urban Hazard Information In- frastructure (UHII) in Windhoek, Namibia, in the core research, and sets up the framework for its development based on the different experiences coming from case studies. The investigation of a demand and potentials for UHII and its core element UHEMIS (Urban Hazard and Emergency Management Information System) is done after an analysis of UHII re- quirements in the different institutional environment of Regionale Brandweer Twente (the Nether- lands) in the preliminary study. The identification of bottlenecks in urban hazard data manage- ment in different organisational environments of case studies and their implications for decision- support by UHII in the framework of integrated Urban Hazard Management (UHM) was pre- sented. The As-Is Spatial Information Management Reference Model (RSIMM) is created for the preliminary study and used as a reference to the Case-Specific Spatial Information Management Model (CSIMM) for the City of Windhoek (CoW), the core research, where young, dynamic institutions face financial, structural, legal and technical uncertainties. As a result the institutional and technical framework for spatial data exchange and sharing in Integrated UHMis proposed. The combined soft-structured methodology with the use of Critical System Approach for analysing demands and requirements for development of UHII in Windhoek is developed. The reference to the lessons learned from the case studies is made and the guidance through required policies and strategies supporting UHII development is presented. The Urban Hazard and Emergency Management Information System (UHEMIS) development is chosen to initiate UHII introduction. It is meant to constitute a data and metadata management base for decision-making in spatial development control, risk assessment and emergency response plan- ning. The UHII and UHEMIS models are being designed next in this research. A framework for co-operation between the CoW divisions and external spatial data providers is advised be established to supply UHEMIS and UHII with accurate, reliable and up-to-date spatial data.
