This is a PhD early stage proposal presentation in brief of preliminary findings of a research titled: Home owners’ responses to crime in Dar es Salaam Tanzania: its implications to urban architecture, urban planning and management theories and practices. As a background, the paper highlights the research problem, objectives, questions or issues and the research propositions. Further and in a nutshell the paper outlines the aims of the research as: to investigate and document in order to understand the physical (or architectural) responses against crimes of burglary and home robberies, to investigate in order understand the social relationships between the residents from the gated dwellings and residents outside the dwellings and to investigate in order to understand the challenges or implications of the relationship to the practice of architecture, urban planning and management in Dar es Salaam Tanzania. The paper takes off by reviewing theories on crime prevention strategies.Combating crime is often associated with increased policing, more severe punishment of criminals, social and educational programs, and programs for poverty eradication. In the last decades, there has been an increasing interest in the potential of the built environment to contribute to crime reduction. Jane Jacobs stresses the roles of residents- “the eyes of the street”. Oscar Newman developed a more detailed but similar approach to Jane Jacobs on the subject matter. He proposed four categories for discussion of defensible space theory. In research and practical policies it is nowadays often recognized in the developed world that the design of buildings, streets, parks and other public places can deter criminal activity and enhance urban safety.Experience through preliminary observations carried out in Dar es Salaam reveal that, homeowners respond to property crimes and fear of it by modifying the built environment on and around their properties so as to avert fear of crimes. As if to say the high wall fences are not enough, some homeowners install barbed wires, razor wires, electric wires and other sharp objects on their fences to forestall climbing. It is proposed that these attempts to address crimes at an individual level have consequences that are detrimental to urban architecture and planning. Literature review in this direction of research has shown that very little study has been done in Africa south of the Sahara. This is more so in the cities in East Africa, and Dar es Salaam in particular. This research is therefore intended to fill this knowledge gap. Much is to be achieved in Tanzania as planning regulations have to be revised and as informal settlements are being regularised.The implications for the preliminary findings are that: the public streets become free zones for the bad guys; the utility agencies cannot easily access the dwellings in an effort to collect utility charges. Safety of residents in these homes becomes at risk in case of fire. Homes are not easily accessible whenever emergency needs arise from without the gates. The streets become lonely at night and a sense of being unsafe when walking in them is felt. It looks as though one is walking through a forest!The paper ends by calling for review of the way residential neighborhoods are planned from grid type of street design to clusters with cul-de-sac street designs and design residential areas that enhance community spirit of cooperation.
