During the decade of 1950s, the intensive rural to urban migration, in search for new job opportunities, created a high housing demand that was partially solved by the dictatorial government of Marcos Perez Jimenez. However, in the absence of effective public policy and failed housing projects, the population started to create solutions of their own to satisfy their housing needs, settling themselves in an improvised way around the urbanized areas and constituting what we know today as informal settlements or barrios. By 1957, around 35% of the population of Caracas lived in barrios. During the past decade, Venezuela has experienced a series of changes that have modified the economic, political and social model that governed the country. During Chavez's government, there have been many policy changes regarding property, land, economic and social organization, in search for solutions to the housing problem that integrate the marginalized sector of the population. However, a different pattern of informal settlements has emerged. Some organized communities have started to invade not only vacant land in the city peripheries; they are now invading buildings that are inserted in the center of the city, contrasting to the formal systems already existing in the city. There is now a new interpretation of what is legal and what is not. We are experiencing the changes and understanding the consequences of their implementation. The purpose of this research is to understand the current processes of housing production and acquisition in formal and informal communities in Caracas through a review of existing literature and qualitative studies of the relationships between stakeholders. I analyze the new policies and the current housing production organization system and contrast it to what is actually happening in practice. I also investigated how incremental changes in existing practices can contribute to the development of safe and legible housing production processes. My recommendations are the result of hybrid systems that consider different actors and perspectives of the same reality in order to find a healthier and more sustainable building culture in Caracas. / text

This paper will build upon the idea that informal settlements communities develop characteristic spatial morphologies as a response to outside forces. By understanding those forces and the resulting use of space, in particular public spaces, we can develop more appropriate urban design and planning interventions based in local realities. I begin by presenting the urban theories of Christopher Alexander and Bill Hillier, which provide analytical tools for understanding public space morphologies and the uses of public space. I then introduce Asef Bayat’s concept of quiet encroachment to more fully theorize the characteristics of public space as a response to the outside forces, in particular as an informal means of claiming space and rights to the city. Finally, I draw on this analytical and theoretical framework to analyze public space in the informal settlement of Jallah Town, in Monrovia, Liberia. I conclude by outlining how these analytical and theoretical tools can be used to further urban theory and international development and planning practice in informal settlements. / text

This statement forms the basic premise for the proposed research study. An attempt has been made to search for the inherent order in the seemingly "unplanned" squatter settlements. / Spatial order, an expression of the socio-cultural milieu of the residents, needs multi-disciplinary analysis. The research methodology selected encompasses the principles of spatial (morphological) analysis and the field work techniques of ethnography. Data has been collected empirically from the field. Since the proposed research uses a case-study research design, analysis and interpretation is qualitative rather than quantitative. / The study has been conducted in a trial and error, sequential process. Various models and methods have been used in this search for spatial order. The process tested the hypothesis at different levels---geometric, functional and social, and finally documented the residents' viewpoints. This was deemed essential as the residents are the actual generators of this built environment. The first two levels could not verify the hypothesis on their own accord but when overlaid by the third component, all three added-up to indicate the existence of order in squatter settlements.

Water is the most important resource which is essential for sustaining all life forms, since without it, life cannot exist and industry cannot operate. However, increasing concern is being expressed at the rate of degradation of this important resource, which, to a large extent, is due to the advent of industrialization and urbanization. The major causes for this concern is that the progress towards urbanization is often made without due regard to the consequences. Furthermore, the effect of man's social and industrial activities can be seen in the extent to which river water quality changes as a river flows from its source to the sea. Water which is returned to the river as effluent is rarely the same quality and is normally contaminated with some form of pollution. South Africa is a country where water is a scarce and precious resource. Coupled with low rainfall and a high evaporation rate, is the lack of basic services which are concentrated in areas where demands of the most vital resource is ever increasing. In addition, urbanization is experienced at a phenomenal rate, much of which is in the form of informal settlements. These constitute overcrowded "shacks" with no running water and sanitation facilities. Furthermore, imbalances in the ecosystem are created when humans strive to undertake the economic demands of the world resulting in poor environmental management practices and unhealthy living conditions. These communities lack basic services and as a result, resort to environmental degradation where the removal of vegetative cover, waste disposal and water pollution are evident. Furthermore, many of the informal settlements are situated in close proximity to water source, especially rivers. In the absence of sanitation, these communities make use of shallow pit latrines, river banks, etc. The potential for pollution is therefore very high in these communities. This provided the researcher with theThe purpose of the study was to determine the influence of the Umlazi informal community, L-SECTION on the water quality of the Umlaas River. The physical and chemical parameters viz., pH, E-coli, COD, turbidity, electrical conductivity, nitrate and phosphorous concentration were examined to provide the researcher with some indication of water quality. Water samples with an interval of 100 metres apart were collected upstream and downstream of the informal community. The samples were analysed at the Metro Waste Water management laboratory to determine the concentrations of the said variables. The purpose of upstream and downstream sampling was to enable the researcher to determine whether the difference in values between the two sets of data was significant or not. The statistical test was achieved through the application of the students t test. The results of the investigation indicate that water downstream of the informal community is of a poorer quality than that of upstream. The results of the application of the test for each set of variables (upstream vs downstream) reveals that the difference is significant. The findings of the study indicate that the informal community have a detrimental impact on water quality. Authorities responsible for management of water resources are required, as a matter of urgency, to implement nec~ssary steps to ensure that water quality is not impacted upon negatively. Failure in this regard could lead to the following: a decline in water quality and quantity; a reduction in economic opportunities; deteriorating standards of human health and safety as well as a decline in the diversity of plants, animals, and fish in our rivers. However providing proper sanitation to people living in informal settlements; improving the quality of lives of the homeless people who resort to squatting as well as ensuring that policies ensure that minimum standards requirements are met are just some of the steps in overcoming the problem in water quality. motivation for the study. / Thesis (M.A.)- University of Durban-Westville, 2003.

Environmental degradation from problems of the 'Brown Agenda' is an everyday reality in Kenya's rapidly growing urban centres; and it is the low-income majority who are most affected. Deficient water supply and sanitation, inadequate solid waste disposal, and poor drainage are among the foremost problems that characterize informal settlements in which indigent urbanites are compelled to live. Analysis of environmental problems at settlement and household level can provide vital information about the appraisive environmental perceptions and cognitions of inhabitants of informal settlements, as well as their satisfaction with the infrastructural services to which they have access and their housing conditions, in general. Such information is essential to the formulation of apposite strategies for sustainable improvement of environmental conditions in informal settlements. Based largely on a comprehensive review of theoretical perspectives on the urban housing question in the South, international policy responses and experiences with settlement upgrading, this thesis seeks a better understanding of the socioeconomic and physio-environmental dynamics of urban low-income informal settlements and the formulation and implementation of upgrading policies. A comparative analysis of two majengos in Kenya-one of which has been upgraded while the other has not-serves to contextualize the study. The central thesis in the present study is that settlement upgrading is the most rational approach to improving the residential circumstances of the urban poor majority in Kenya. Applying a fundamentally liberal approach, the development of pragmatic opportunities is discussed, and pursuable policies and programmes, which are realistic and implementable, for effective environmental planning and management of urban low-income informal settlements in Kenya are proposed.

Built space In Yemen is observed through the forms taken from the earliest phases of the process of building and dwelling In an agricultural territory to the Increasingly complex expressions of settling and developing urban structures, before and after the Republican Revolution of 1962. The Revolution is seen as a turning point in building methods and attitudes; and the twenty years that followed the consolidation of the Republican regime in 1970 exuberantly illustrate the results of the country’s consequent exposure to an industrial culture hitherto unknown. The manifestations of pre-Revolution times and those taking shape in the subsequent twenty years are approached from parallel points of view. The later period, however, includes not only a study of built form but also the declared intentions for planning growth and conservation within the environment as a whole. Disruption appears as a consequence of cultural change and the mitigation of its effect as a government responsibility. Consolidated forms of domestic architecture are studied and a basic distribution pattern of regional variations is proposed. New approaches in the process of building may be creating original idioms and radicalising economic and stylistic differences between the urban and the rural contexts. An attempt is made to identify meaningful trends.
