Regional planning in the Kilimanjaro/Arusha region of Tanzania

Mosha, Aloysius Clemence January 1975 (has links)
The need for regional planning in Tanzania has long been realized because in this country, as in most developing countries, there are striking contrasts and disparities between regions, clearly reflected in the very unequal opportunities to participate in the social-economic development process enjoyed by the various population groups. The sheer size of the country would make it difficult to treat the country as a single unit, even if the undeveloped transportation system did not further divide the country. These problems have thus prompted the undertaking of this thesis which tries one approach to Regional Physical Planning in Tanzania to see whether this level of planning can solve some of the problems and thus lead to better development in this country. The Study starts off with an examination of the Regional Planning experience of some African countries including a thorough examination of Tanzania's experience before embarking on a case study of one of its regions. The Northern Reglon has been taken for this detailed case study. It is a region with major contrasts in factor endowment and urban development. An analysis of the present situation shows that this region has tremendous resource potential, especially agriculture, industry (especially processing industry), tourism and abundance of labour. However, development has been limited because of some problems facing this region. These include rapid urbanization leading to differences between urban and rural areas, haphazard location of infrastructure resulting in duplication of services in some areas while others have none, land shortage and population congestion problems in the highland zones. The analysis paid special attention to tourism because of its present importance in the economy and development of this region. The results of the Analysis of the existing situation formed the back-ground to the formulation of goals and objectives, a general outline of Alternative Strategies and their evaluation. This led to the choice of the preferred Strategy which was taken and developed as the future Strategic Plan of this region. This Study has recommended a strategy to solve some of the region's identified problems while exploiting existing potentials for growth. The resulting document should, initially, be discussed by local politicians and departmental specialists. Further detailed research and surveys and, feasibility studies would then be needed before implementation can be contemplated. The Plan suggests that a Growth Centre Strategy should be used as a basis for future development by both Local Government and private agencies. This planned spatial distribution of centres would ensure a balanced relationship between the urban and rural sectors. Investment priorities would be in the centres currently lacking essential services and infrastructure. Such a Strategy will maintain a reasonable spread of urban services throughout the region thus ensuring that opportunities for educational and cultural improvement, together with medical and commercial facilities are reasonably accessible to all the rural population. Certain concrete proposals have been made for immediate implementation such as the upgrading and provision of additional infrastructural development in. the selected service centres. Special projects for agriculture and industry have also been suggested. These proposals have been integrated into a long range development PLAN for the Northern Region which recommends a pattern of growth which will accommodate all anticipated development up to the turn of the century. The successful implementation of this Plan will depend on the suggested establishment of a Regional Planning Unit which would constantly review the plan in the light of future new developments. Thus, it remains as a flexible strategic regional plan, unlike previous unco-ordinated sectoral and inflexible Master Plans for limited areas. If this planning approach is successful, it may, in future, be used as a general blue print for regional planning in Tanzania.

Contextual integration in waterfront development

Abdul Latip, Nurul Syala January 2011 (has links)
The relationship between waterfronts and water in the establishment of many cities is undeniable. Issues as to why many waterfront developments do not respond to their water are often raised. This thesis examines the response of waterfront development towards its water (in particular the urban rivers). This is measured through the level of contextual integration in the city centre of Kuala Lumpur to identify the reason why this situation exists. The research employed the qualitative method using a case study approach. It triangulates several techniques, which include morphological study, field observations (visual survey, direct observation, activity mapping), focus groups and in-depth interviews. The theoretical framework was based on the Integrative Theory of Urban Design, which has five main principles comprising ‘good form’, ‘legibility’, ‘vitality’, ‘comfort’ and ‘meaning’ from which thirteen attributes were extracted. The research found a mix of levels in the contextual integration of the KL waterfront for all attributes evaluated. Five attributes that affect the level of contextual integration the most are the ‘direct access’, ‘physical character of urban river’, ‘seating’, ‘development that addresses urban river’ and ‘shade’. This study inferred that the other related attributes borrowed from other public spaces are vital to achieve the response of waterfronts towards the urban river. However, the evaluation criteria have to be suited to the local context. Twenty-one factors were identified that affect the level of contextual integration. Three reoccurring factors in seven out of the thirteen attributes evaluated are ‘the existence of highway’, ‘fenced private property till the edge of the river’ and ‘building built abutting the river edge’. It also gathered that the contextual integration between the waterfront and the urban river can only be achieved with the interrelation of the physical and functional dimensions. Eight key reasons were established as to why the waterfront is not contextually integrated with the urban river, these are i) lack of planning – policies, laws, guidelines, master plan, ii) limitation of funds, iii) condition of the river, vi) introduction of other transportation systems, v) lack of coordinated management, vi) political will, vii) lack of awareness and viii) market demand. These findings contribute to the gap in many queries and assumptions concerning this issue from the perspective of a city centre in an emerging Asian country.

Rural Texas infrastructure : assessing needs and financing capital improvements / Assessing needs and financing capital improvements

Elder, Lucy A. 08 August 2012 (has links)
Rural communities play a significant role in the State of Texas economy. The economic success of these communities depends heavily on maintaining adequate public infrastructure systems. This report examines the infrastructure needs of 11 rural Texas cities to identify gaps in funding resources available through state and federal grant and loan programs for infrastructure improvements. Primary findings conclude that inadequate funding support for rural infrastructure improvements through state and federal grant and loan programs exists primarily for water and wastewater infrastructure improvements and street and sidewalk improvements. In addition, the report outlines limitations specific to rural communities in obtaining various forms of capital financing that include a limited tax base, limited access to borrowing and lack of economies of scale as well as various demographic characteristics that contribute to these limitations. / text

Dispersal-diversity relationships and ecosystem functioning in pond metacommunities

Howeth, Jennifer Gail, 1979- 12 October 2012 (has links)
Insights gained from metapopulation and metacommunity biology indicate that the connectivity of subpopulations and communities by species dispersal can profoundly impact population dynamics, community structure, and ecosystem attributes. Recent advancements in metacommunity theory further suggest that the rate of species dispersal among local communities can be important in altering local and regional species richness and ecosystem functioning. The role of species dispersal rates relative to patch-type heterogeneity and associated intrinsic community structuring mechanisms (competition, predation) in affecting diversity of multi-trophic communities, however, remains unknown. Here, I address the relative influence of regional and local processes in altering species richness and ecosystem functioning at multiple spatial scales in freshwater pond metacommunities. In a series of experiments, I employed pond mesocosm metacommunities to manipulate planktonic species dispersal rates and the incidence of top predators which differed in prey selectivity. The consequences of dispersal and predation to zooplankton species richness, trophic structure, ecosystem stability, and prey traits were evaluated. Generally, my findings support predictions from metacommunity models, and demonstrate that dispersal strongly affects community and ecosystem-level properties. In accord with dispersal-diversity theory, dispersal rate affected species richness and ecosystem stability at multiple spatial scales. The presence, but not the rate, of dispersal had strong effects on the partitioning of biomass amongst producers, grazers, and top predators. The relative influence of predation on local and metacommunity structure varied across experiments and largely depended upon predator identity and the degree of feeding specialization. The research presented herein is some of the first work to evaluate how species dispersal rates can affect dispersal-diversity relationships, diversity-stability relationships, trophic structure, and the distribution of prey traits in metacommunities. In addition to advancing ecological theory, the results have important implications for conservation as fragmented landscapes become increasingly prevalent, and local and regional biotas modified. Ultimately, it proves critical to identify drivers of local and regional species richness in order to maintain biotic integrity at the global scale. / text

The social construction and reconstruction of community

Bateson, G. January 1996 (has links)
Community is a complex term whose usage within sociology has ranged from being a key idea to being dismissed as irrelevant. At the same time as its virtual dismissal by sociology, community continued to have widespread usage within everyday language and as an adjunct to social policy. Its ubiquitous nature and the lasting power of the concept were evident at the outset of this research and created a number of contradictions that were considered worthy of further exploration. This thesis surveys sociological approaches to community and relates the career of the concept to changes in the political and economic context. A new approach is suggested which captures both the dynamic, kaleidoscopic nature of the concept at any one time and the layered, archaeological nature of its development over time. This provides a way out of the impasse of traditional sociological approaches to community. The approach proposes that different conceptualisations of community can be constructed through specific fragments of meaning being differentially articulated to produce various constellations of meaning. Partial fixations of meaning, within any one particular context, and the existence of common elements allow a description both of the uniqueness and generic nature of the concept. This provides a model for the conceptualisation of community and this has been applied to ideal type descriptions of community and to a number of well-known community studies. Empirical explorations of the conceptualisation of community were undertaken at CastleV ale, Birmingham. Conceptualisationso f community were recordedf rom the various perspectives of residents, local workers and local media. These were related to patterns of historical development and to recent political and economic restructurings. Different stakeholders' approaches to community were related to the time of the estate's construction (1960s), the time of settlement and adjustment (1970s), the time of reduction in state social intervention (1980s) and the time during which the estate took on Housing Action Trust status (1990s). Different and overlapping conceptualisations of community were explained using the approach already developed. From this it was possible to describe ways in which the wider context interacts with day-to-day lifestyle practices through representations and understandings of community. A loose typification of community at Castle Vale has been developed. Taking the discussion further allowed a device to be developed for the description of various conceptualisations of community, and allowed a framework to be developed within which different conceptualisations of community have been located. This work has allowed a reassessmenot f the position of community within sociology at the present time. It identifies those areas of momentum that are re-establishing community on the political and social agenda, suggests that the time is now right for sociology to reformulate a more adequate approach to community, and asserts that the approach developed aids moves towards new theoretically-informed ways of conveying the complexities of life at a local level within a more globalised context. It is a community study more appropriate for this age and is part of the enterprise of developing more sophisticated approaches to community.

Happiness and environmental quality

MacKerron, George January 2012 (has links)
Subjective wellbeing — happiness — is of increasing interest to economists, including environmental economists. There are several reasons for thinking that environmental quality (EQ), defined as high levels of environmental goods and low levels of environmental ‘bads’, will be positively related to happiness. Quantitative evidence on this remains limited, however. Some papers use cross-sectional data aggregated at country level, but it is open to doubt whether these aggregated measures reflect individuals’ real EQ exposures. Other papers use individual-level data, but in general have spatial data at very coarse resolution, and consider a limited range of EQ variables, exclusively around individuals’ homes. This thesis reports two related strands of work. The first designs, implements and analyses data from two new cross-sectional surveys. It builds on earlier work by using spatial data at very high resolution, and advanced Geographical Information Systems (GIS) techniques; by simultaneously considering multiple EQ characteristics, around both homes and workplaces; and by investigating the sensitivity of results to the choice of happiness indicator. The second strand develops and implements a new methodology focused on individuals’ momentary experiences of the environment. It extends a protocol known by psychologists as the Experience Sampling Method (ESM) to incorporate satellite (GPS) location data. Using an app for participants’ own smartphones, called Mappiness, it collects a panel data set comprising millions of geo-located responses from thousands of volunteers. EQ indicators are again joined to this data set using GIS. Results of the first strand of work are mixed, but support some links between happiness and the accessibility of natural environments, providing quantitative (including monetary) estimates of their strength. The second strand demonstrates that individuals are significantly and substantially happier outdoors in natural environments than continuous urban ones. It introduces a valuable new line of evidence on this question, which has great potential for future development.

Unsettling the culture panacea : the politics of cultural planning, national heritage and urban regeneration in Buenos Aires

Dinardi, Maria Cecilia January 2012 (has links)
This thesis is concerned with how a controversial heritage redevelopment project in downtown Buenos Aires enables social actors to produce and contest meanings of culture, the city and the nation. The research is an in-depth case study of the politics of a culture-led urban regeneration project converting the Palacio de Correos y Telecommunicaciones (the post office national headquarters)into a cultural quarter in the context of Argentina's bicentenary commemorations. Taking the building as the object of study, the investigation draws on interviews, archival research and analysis of discourses and images to shed light on the material institutional and historical configurations of cultural planning from a sociological cultural perspective. The aim is to explore the complex interplay between culture, memory and space through three analytical dimensions concerning the rise, fall and rebirth of the building. First, the thesis considers why culture provides a solution to the deterioration and disuse of the postal place. Second, the politics of memory of the cultural centre is examined through its engagement with the past, present and future of the building. Third, the type of urban space imagined for the renovated site is discussed in relation to similar projects in the city's central area. The multifaceted analysis shows how the post office headquarters becomes entangled in a network of public discourses, memory struggles, material interests and political confrontations, mediated by the language of culture. The thesis argues that policy-makers invoke culture as a claim to legitimacy that is meant to appeal to those reject political parties and politicians and that us aimed at wiping out the conflicting social histories of places. The variety of meanings assigned to culture reasserts the contention over the term and demands empirical analyses that, grounded in specific contexts, resist the prevalence of universal cultural regeneration recipes, challenging culture's function as panacea.

Governing with the citizens : strategic planning in four Italian cities

Bussu, Sonia January 2012 (has links)
In recent years there has been much political and academic interest in new modes of local governance, which are increasingly based on deliberative mechanisms and aim at engaging larger sectors of the population (i.e. governance by networks, territorial pacts, strategic planning). Whereas the literature on urban governance has focused on the emergence of novel governance arrangements at city and regional levels and on the formation of a collective actor, deliberative democracy scholars have examined the democratic dimension (i.e. the deliberative forums) and assessed the applicability of their normative models to the real world; the literature on planning helps to understand the implementation gap that plagues many of these new arrangements. All these approaches often study the same empirical phenomena, however, with a few exceptions, debates within these literatures take no account of one another. This comparative case-study of strategic planning in four medium-sized Italian cities (Trento, Prato, Lecce, and Sassari), characterized by different socio-political and economic contexts, intends to contribute to bridging the gap between the above theoretical paradigms. Thus, the impact of strategic planning on the local polity is assessed on three levels: the formation of a collective actor, the democratic process, and implementation. Comparative analysis can help to evidence how such an impact is either hindered or enhanced by different forms and resources of leadership and how the latter interact with endogenous (i.e. pre-existing associational density) and exogenous factors (i.e. institutional constraints and opportunities at other jurisdictional levels). Different typologies of leadership will influence each dimension of the dependent variable (i.e. the formation of the collective actor, the democratic process, the implementation) to varying degrees. The type of leadership now required within the new multilevel governance system could be defined as facilitative leadership, which arises from the activity of working with, rather than exercising power over, others. This leadership is no longer identified solely with political institutions but often emerges from the coordinated work of a political sponsor and a public service CEO that acts as the champion of the governance process. Institutional constraints might affect outcomes, as weak administrative capacity and resistance to change from within the bureaucracy will hinder implementation. A facilitative leadership can help to drive cultural change and organisational learning within local institutions, while offering identity incentives to the wider community. While pre-existing associational dynamics do not influence outcomes, since an inclusive leadership can encourage greater participation even where the social fabric would seem weaker, poor policy coordination among jurisdictional tiers will inevitably hamper the positive effects of strategic planning at the local level, which might be lost in a plethora of fragmented initiatives.

A tale of three cities? : mediated imagination, class and the many young cosmopolitans of Cairo

Elsayed, Heba January 2011 (has links)
This thesis has explored the ways in which young Egyptians construct different classed versions of a cosmopolitan imagination while located in the megacity of Cairo. In an intense ethnographic study, I have examined the ways in which young men and women shape their identities at the juxtaposition of a social reality, which is rigidly structured around classed and gendered divides on the one hand, and a diverse and fluid system of media representations of the self and others, on the other hand. Focusing on everyday life in Cairo has allowed me to examine the contradictory social and cultural experiences associated with being young in a megacity of the global south. Whilst the daily urban lives of these young Cairenes are located within embedded structures that place firm limits on their social and physical mobilities, the city is also a more creative terrain where these highly structured limits on the self are negotiated. As young people move physically in the city, yet shift imaginatively between different systems of representation available to them in the rich mediascapes they have access to, their sense of identity expands. Specifically, this cosmopolitanism takes the form of a dynamic subjective space and a category of imagination from within which identities, drawing heavily on globally circulating media products, are reflexively understood and interpreted. Thus, operating from within repressive, socially fragmented, yet highly mediated everyday contexts, I explore how young Egyptians construct three different versions of a cosmopolitan imagination: closed cosmopolitanism as imagined by the upper middle class, critical cosmopolitanism relating to the experiences of the lower middle class, and for the working class, an implicit cosmopolitan imagination.

Green visions and democratic constraints : the possibility and design of democratic institutions for environmental decision-making

Wong, James Ka-lei January 2012 (has links)
This thesis addresses a recurrent question of our time – whether democracy can secure environmental sustainability – by drawing on literatures in the normative theory of democracy, social choice theory and environmental politics. I propose a basic, yet substantial organising principle, the ‘dilemma of green democracy’, which maps out the possibility of realising green outcomes under democratic constraints. Interdisciplinary ideas from neighbouring disciplines are also imported for the purpose of studying the design of good environmental-democratic institutions. The analytical framework is an integrated one, comprising formal choice theory and normative democratic theory. The first part of the thesis focuses on the possibility of environmentaldemocratic institutions. Chapter 1 introduces the dilemma of green democracy – a conflict between three plausible desiderata for environmental democracy – and suggests several proposals for avoiding the dilemma. It concludes that, as long as the dilemma is resolved, it is logically possible to construct environmental-democratic institutions. Chapters 2, 3 and 4 assess the desirability of the different proposals in terms of procedure and outcome. The general conclusion is that whether these proposals are desirable depends on a number of conditions and/or contextual factors. The second part of the thesis examines the substantive issues in designing environmental-democratic institutions. Chapter 5 discusses how the discursive dilemma in social choice theory and the normative ends of deliberation constrain the inputs of such institutions. Chapter 6 demonstrates how the concept of distributed cognition, drawn from cognitive/computer science, reconciles the tension between technocracy and democracy. Chapter 7 suggests how the theory of cognitive dissonance, drawn from psychology, challenges the epistemic performance of practicable (environmental-) deliberative-democratic institutions. The overall conclusion is two-fold. First, democracy can, at least in principle, secure environmental sustainability, provided that the dilemma of green democracy is resolved. Second, interdisciplinary ideas are useful for designing good democratic institutions for collective environmental decision-making. This conclusion has implications not only for intellectual enquiry, but also for institutional design in practice.
