In 1979, the Chinese government introduced the One-child Policy for the purpose of controlling population growth. Thirty years later, the fertility rate in China has declined to a very low level and one-child families have become the norm. At the same time, the consequences of low fertility rates have emerged. In 2015, the government announced a new policy that encouraged couples to have two children in order to raise the total fertility rate. In this paper, I analyze the economic and legal implications of the Chinese family planning policies. By examining to what extent fertility decisions are affected by government policies, I evaluate the potential effects of the Two-child Policy. The findings suggest that the Two-child Policy might not be effective in increasing the total fertility rate.

The approach of the study is historical and institutional. The thesis compares the performance of the pre-war Nigerian economy to its post-war performance. The study analyzes the role of petroleum production, agriculture, and the banking system as the major generators of growth in the economy. It portrays the political framework of the country, and endeavors to give a clear and concise understanding of the economic and political implications of the war. Development planning policy issues are examined and evaluated to ascertain the degree to which Nigerian planners are fully aware of the nation's development obstacles.

Traditional historiographic research is challenged by the very nature of post-modernism which, in terms of one of its less radical viewpoints, views history not so much as truth-seeking, nor objective activity, but rather re-interpreting it as story-telling and as history reflective of itself -an approach which have determined the nature and style of this study. The study was prompted firstly by my exposure to the legacy of apartheid with regards to land and past planning policies while working at the Department of Land Affairs, and secondly by my personal involvement in Hammanskraai/Temba. The latter straddles the border of a former homeland, formed part of the previous governments' border industry programme, suffers tenure problems on land-ownership issues and is bisected by two present provincial boundaries. For a long time to come Hammanskraai/Temba will struggle to overcome results of modernistic grand apartheid policies as reflected in gross inequalities, uncertainty and the like. The aim of this study was therefore to form an understanding of the grand generalising and local narratives regarding borders, boundaries and barriers in the Hammanskraai/Temba area, as well as the influence of the discourses of development intent on the area and its people. In order to address the issues it was necessary to deconstruct the discourses in development intent that affected the Hammanskraai/Temba area, and to tell the respective role players' stories of the shaping of borders, boundaries and barriers in the area, as well as to play off the various discourses in grand, local and expressive narratives, as it is still unfolding. Instead of giving an 'all encompassing truth' or deliberately simplifying the 'story' in order to fit into a logical, chronological structure (arguing 'modernisticly', so that the reader cannot do otherwise than to agree with the argument), I rather opted towards telling some of the stories reflecting on various experiences regarding borders, boundaries and barriers in the area. There are stories of artificial boundaries, of racists and capitalists, of land and tenure, of division, separation, independence and later integration, of reserves and their underdevelopment, of people suffering and struggling, and of unviable towns and demarcations. In these stories the immense influence and effect of policies and development intent on peoples lives, as well as on the physical, social and economical environment, are illustrated. However, the stories illustrate that not only were complicated barriers created, but also how in some cases, they were perpetuated and enhanced. The value of this historical narrative, lies in the way it makes sense of events, actions and experiences, bringing forward stories that 'deserve to be told', thus opening up a new way of looking at planning and planning history. It illustrates the complexity and intriguing relationships and problems of an area influenced by a magnitude of modernistic planning policies and actions, casting a glimpse on the effect of borders, boundaries and barriers on the lives of those who have to live with it, cross it, or in the worst instances, struggle against it - somehow always with a glimmer of hope. / Dissertation (MTRP)--University of Pretoria, 1997. / gm2014 / Town and Regional Planning / unrestricted

[pt] No último século, o mundo tornou-se um mundo urbano e as cidades passaram concentrar um maior número de pessoas (com mais de 50 por cento da população mundial residindo nelas). Atualmente, os desafios socioambientais que as cidades enfrentam impulsionam novas alternativas para o planejamento urbano atual. Nessas condições é esperado que as cidades sejam foco de mudanças e encontrem novas possibilidades na área do planejamento de cidades levando em conta os aspectos de resiliência e sustentabilidade durante a elaboração da Política Municipal. Essa pesquisa trata-se de um estudo de caso realizado na Cidade da Bogotá, capital do país da Colômbia, que avaliou o Plano de Ordenamento Territorial – POT (como instrumento de planejamento) e o comprometimento do mesmo, com a construção de resiliência em uma cidade altamente susceptível à mudança climática, com muitos desafios de dinâmicas populacionais, espalhamento ao longo de áreas rurais, problemas de mobilidade e deficiência da infraestrutura, cada um com sua necessidade de atendimento no planejamento em questão. O objetivo é conhecer qualitativamente, se o Plano tem orientação e pode contribuir na construção de resiliência urbana. A metodologia usada foi desenvolvida na pesquisa prévia de Lemos (2010) e envolve categorias de sustentabilidade e resiliência, com os possíveis efeitos de ações descritas no Plano. Após a aplicação metodológica e revisão do POT, os resultados demonstraram que o Plano está orientado para a resiliência, porém a sua contribuição é frágil na definição ações conjuntas em diferentes níveis do poder político. / [en] The worldwide population rises in an accelerated way, especially in the regions with low economical and institutional capacity to guarantee the organized urban development, which allow the mixture of land use, the preservation of nature within the city and maintain the health and well-being of the citizens, while takes economic prosperity to the country. The population growth and the worldwide production are happening with models and Technologies that are unsustainable. This picture has multiplied the pressure over the environment, causing a climate change with consequences still unpredictable (ONU HABITAT, 2009). The climate change sets up new challengers mainly to governments and planners and designers that have to face up the uncertain of the future events. In the middle of this real situation and according to was mentioned by URWIN and JORDAN, 2007 now is more evident that new policies in climate and nonclimate sectors will need to be designed in ways which facilitate rather than hinder adaptive decision. Against this backdrop arises a vision of planning from the perspective of resilience, term that is defined in ecology, persistence of relationships within a system and is a measure of the ability of these systems to absorb changes of state variables, driving variables and parameters and still persist (Holling, 1973). This concept is complemented later by Walker (2004), including also the capacity of the system to reorganize itself in the middle of changes, in order to maintain the same function, structure, identity and feedback process.

This thesis addresses three interlinked aspects that are relevant for mainstreaming Nature-based Solutions in urban planning. The first aspect concerns the integration and use of ecosystem service knowledge in spatial planning. A literature review aimed at analysing practical applications of ecosystem services in real-life planning processes and instruments reveals both the outcomes generated and the procedures adopted to integrate them, as well as the main advantages, constraints, enabling factors, and open issues associated with ecosystem service knowledge integration in spatial planning processes and instruments. The second aspect is related to the use of spatial assessments of ecosystem service demand to support an effective planning of Nature-based Solutions at the city scale. An approach is developed to allocate and prioritize Nature-based Solutions in cities in order to deliver ecosystem services for addressing the existing urban challenges while maximising the benefits for residents. The approach is tested in the case study area of Valletta (Malta), identifying the potential sites for the implementation of eleven types of Nature-based Solutions, assessing the demand for five priority ecosystem services, and identifying what type(s) of Nature-based Solutions, among the eleven proposed, should be implemented in each potential site, as well as the sites that should be prioritized first. The third aspect involves the promotion of the implementation of Nature-based Solutions in urban plans through the use of suitable policy instruments. A matrix that links the suitable instruments identified to different typologies of Nature-based Solutions reveals the range of instruments that can be deployed to promote the implementation of each type of Nature-based Solution. The matrix is then applied to analyse which instruments are currently deployed and which are not in the two urban plans covering the case study area of Valletta, hence the missing opportunities that could be further exploited.

Résumé : La coordination entre les politiques d'urbanisme et de transport, dans un nouveau contexte façonné par la montée en puissance des préoccupations environnementales et des enjeux du développement durable, est plus que jamais recherchée afin d'assurer une meilleure cohérence entre ces deux domaines. Ce travail a pour objectif d'analyser la place des politiques de mobilités urbaines au sein d'une politique plus globale de développement urbain durable.Beaucoup d'innovations et de bonnes pratiques dans le domaine du transport, proposant des modes alternatifs de déplacement, ont été adoptées pour répondre aux exigences du développement durable et surtout pour tenter de diminuer la place de la voiture particulière. Pour ce faire, des actions technologiques et organisationnelles doivent être insérées au sein de formes urbaines alternatives favorisant la ville à courte distance et la mixité et renforçant l'accessibilité (une des facettes du lien entre transport et urbanisme). De ce fait, la coordination et la complémentarité entre les politiques d'urbanisme, d'habitat et de transport ainsi qu'entre les acteurs aux échelles urbaine et interurbaine, doivent être renforcées.Cette recherche trouve son originalité dans l'étude comparative des quatre principales agglomérations de la région Champagne-Ardenne (Reims, Troyes, Charleville-Mézières et Châlons-en-Champagne), agglomérations de taille moyenne qui ont moins été étudiées que les grandes agglomérations. Elle examine comment les questions des déplacements et des mobilités ont été prises en compte dans les documents de planification stratégique de transport (SCoT et PDU). Alors que le lien entre transport et urbanisme se présente comme un des objectifs prônés par la loi SRU, qu'en est-il vraiment de la cohérence entre ces deux domaines en Champagne-Ardenne ? / Abstract : Mobility planning and urban sustainable development in Champagne-Ardenne. Analytical approach of the four main cities of Champagne-ArdenneCoordination between urbanism and transportation policies is more and more demanded in a new context characterized by an increasing concern for environmental issues and sustainable development. This research aims to analyse the role of urban mobility policies within more global sustainable development policies. Many innovative practices have been adopted in order to limit the importance of private cars and to foster alternative modes of mobility. This supposes to integrate technological and organisational actions into alternative urban forms favouring short distance, mixity and accessibility, which needs a better coordination between urbanism, dwelling and transportation policies at both urban and interurban scales.This research takes its originality from a comparative survey of the four main cities in Champagne-Ardenne, Reims, Troyes, Charleville-Mézières and Châlons-en-Champagne, i.e. mid-size cities that have been less studied than greater cities. It appreciates how mobility issues have been taken into account in strategic planning documents (SCOT, PDU). Since the link between mobility and city planning is one of the main objectives of the Solidarity and Urban Renewal act implemented in 2000, how far goes the coherence between these two fields of action ?Key-words : Strategic planning – Mobility planning policies – Urban mobility plans (PDU) – Master plans (SCOT) – Coherence between transport and urbanism – Champagne-Ardenne – Mid-size cities.

Du fait de la flexibilité énergétique qu'ils offrent et de leur potentiel de diminution des émissions de GES et de polluants, les réseaux de chaleur (RdC) sont un des leviers d'actions des politiques énergétiques locales en constante progression. Leur déploiement et/ou rénovation n'est pas qu'une question technico-économique classique, dans la mesure où ils sont au cœur d'un ensemble d'acteurs interconnectés, aux objectifs spécifiques, tous parties prenantes des politiques énergétiques locales. Dans ce contexte, les outils permettant à ces différents acteurs l'évaluation des actions liées aux RdC sont très importants. Ils doivent permettre l'évaluation de scénarios de conception, d'actions de rénovation, de performance et de suivi... Parmi les outils permettant ces évaluations, les approches par modélisation sont souvent trop spécifiques à une situation, un type de réseau un acteur... Le travail réalisé consiste à développer un outils de modélisation de RdC, offrant la flexibilité recherchée. "HeatGrid" permet de modéliser des architectures de réseaux variées. A chaque pas de temps, le fonctionnement du réseau est simulé grâce au formalisme de la programmation linéaire. Cet outil peut être utilisé en phase de conception ou d'exploitation d'un réseau. L'approche de modélisation permet d'évaluer et de comparer sous les aspects économiques, énergétiques et techniques d'un RdC sous différents scénarios. Plusieurs exemples sont simulés et analysés dans le but d'illustrer le potentiel du modèle. / Because of the energy flexibility that they offer and their potential to reduce GHG emissions, disctrict heating (DH) networks are a tool of local energy policies in constant progression. Their develpment and/or renovation is not only a classic technico-economical question, insofar as interconnected stakeholders of local energy policies, taking into account specific objectives, are concerned by DH networks. In this context, tools which enable these different stakeholders to evaluate actions related to DH networks are essential. They must be helpful for the assessment of renovation actions, the monitoring and the evaluation of performances....Among the tools that allow theses evaluations, the modelling approaches are often too specific to a situation, a type of network, a stakeholder... The work of the thesis consists in developing a DH modeling tool that has this desired flexibility. The proposed tool "HeatGrid" can model various network architectures. At each time step, the network running is simulated via linear programming formalism. This tool can be applied either at the design stage of a DH or at the operating stage. The model based approach enables the evaluation and comparison of economic, energy and technical aspects of the DH system in different scenarios. Several examples are simulated and analyzed in order to illustrate the potential of the model.

La thèse porte sur les conditions d’émergence d’une approche territoriale de prévention et de gestion des risques collectifs à l’échelle des agglomérations urbaines. Cette approche s’appuie une définition endogène et extensive du mot « risque », qui vise finalement à un fonctionnement sans incident des villes. Le suivi du parcours des agents administratifs, principaux porteurs de cette ambition dans les trois intercommunalités françaises étudiées (agglomérations de Nantes, de Lyon et du Havre), permet de mesurer la réception de cette approche dans la gouvernance locale et dans le développement des agglomérations urbaines. La première partie de la thèse, qui couvre les années 1960 à 2000, vise à montrer la lente légitimation d’une approche territoriale de prévention et de gestion des risques jusqu’à la structuration administrative de services dédiés. La seconde partie de la thèse, qui couvre les années 2000 à 2006, examine les conditions de leur maintien sur l’agenda. Contre toutes attentes, les agents publics ne réussissent pas à inscrire leur approche des risques dans les politiques d’urbanisme. Par contre, ils parviennent à la valoriser dans la politique locale de sécurité civile. Cette thèse met les agents territoriaux au cœur de l’analyse de l’action publique et de l’évolution des représentations urbaines. Mais c’est dans la confrontation de ces agents publics aux autres techniciens, communaux ou d’État, et surtout dans le rapport aux élus, que se révèlent les enjeux politiques de la prise en compte des risques dans le développement urbain / This thesis is concerned with the conditions in which a territorial approach to the prevention and management of collective risks within city regions has emerged. This approach offers an endogenous definition of risks, linking them to the overall functioning of cities. With a focus on the role of technical and administrative officials, the thesis explores whether the formation of a territorial approach to risks leads to transformations in wider urban development policies The first section presents modes of the territorial definition of risks between 1960 and 2000, used by public officials aiming to justify and legitimate their roles within intercommunal institutions, such as the institutional enrolment of a public action at the level of the city region and the administrative structuring of a dedicated service. The second section analyses the conditions of its continuing importance in the public policy agenda between 2000 and 2006. Against all expectations, public officials found during this period neither an opening nor a foothold in planning policies for their actions. Nevertheless, they did find possibilities for maintaining its importance in the formation of a territorial approach to civil security. The thesis restores the administrative and political role of territorial agents to the core of analysis of public action and of evolving urban representations. Focusing on how the policy of risk prevention and management is framed by a set of technical and administrative discourses, the study retraces the hidden face of the political challenges associated with taking into account risks in wider urban development

Many natural areas and systems within urban landscapes are small or narrow. Landscape ecology studies within forested and agricultural landscapes have found that small natural areas that are protected from development or resource extraction through land use planning are significantly affected by adjacent land use changes. Some eventually lose the values for which they were protected. Studies also indicate that natural area boundary structures and functions are important determinants of the extent to which external threats affect adjacent natural areas. Few studies have empirically tested whether small or narrow urban natural areas that are protected from development through municipal land use planning are significantly affected by adjacent land use changes. However, municipal planners and forest managers are concerned that activities of residents living adjacent to the forest edge, commonly referred to as residential encroachment, may be degrading the social values, and ecological forms and functions of their woodlands. Studies have recorded evidence of human impacts within suburban forest edges, indicating that both recreation and yard-related activities are occurring and that these activities occur at significantly higher frequencies in the forest edge than in the interiors of these forests. However, no study has differentiated residential encroachment activities from those of other recreationists. In addition, although a number of municipalities have developed policies to address these activities, little is known about these policies, the extent to which they are implemented, or their effectiveness in protecting their small or narrow forested natural areas from residential encroachment activities. The principal research questions answered in this research are: 1) Do municipalities within Southern Ontario have policies for protecting natural areas from the activities of residents living adjacent to suburban forest edges? 2) To what extent are they implementing these policies? 3) What encroachment activities, if any, are occurring in Southern Ontario municipal forest edges? and 4) Are municipal boundary-related policies effective in limiting edge-resident encroachment activities? Using a mixed method approach, the research incorporates qualitative and quantitative data collection to answer these questions. The content analysis of official and secondary plans and social surveys of key informants within six Southern Ontario municipalities identify boundary-related policies for protecting municipal natural areas from residential encroachment activities. They also determine the extent to which the study municipalities implement these policies. Field studies in 40 forests within these municipalities used unobtrusive measurements of encroachment behaviour to describe encroachment activities under two implemented municipal boundary demarcation policies, and other boundary treatments The three research methods, together with a literature review, were used to determine whether Ontario municipal policies are effective in limiting edge-resident encroachment activities within municipal forest edges. The content analysis and interviews indicated that, in general, municipal policies were insufficient to address the edge-resident encroachment issue. Policies had been established, but not at a sufficiently authoritative policy level (i.e. the official plan level) to support their implementation by staff. In addition, policies were missing explicit goals, objectives and strategies to direct their implementation, and the municipalities had not integrated their disparate policy components into an integrated course of action through time and space. The municipalities were successful in implementing policies to prevent edge resident encroachment within natural areas adjacent to newly developing subdivisions. However, they had infrequently implemented their policies for preventing encroachment within natural areas adjacent to established subdivisions. Furthermore, all the municipalities were not frequently implementing their policies to remediate existing encroachments within natural areas adjacent to newly developing or established subdivisions. The unobtrusive measurement of encroachment behaviour confirmed that residential encroachment activities generated a housing effect zone of impact within municipal forest edges. The distribution of the evidence of encroachment was significantly biased to the forest border. Encroachment traces were highly prevalent within study forests, occurring in over 94% of sites and covering 26 to 50% of the sampled area. Encroachment traces were particularly intense in the first 8 metres from the forest border; but extended a mean maximum extent of 16 metres from the forest border, with 95% of the evidence of encroachment lying within 34 metres. Boundary type significantly affected the mean frequency, intensity and maximum extent of encroachment. Mean frequencies, intensities and extents of all encroachment, and of most encroachment categories, were generally higher in sites with boundary types that allowed edge residents ready access to the forest edge. Conversely, sites with boundary treatments that had barriers to entry, such as fences or grass strips, tended to have lower encroachment levels. Sites with multiple barriers, such as those with fences, grass strips and paths, tended to have the lowest mean frequencies, intensities and mean maximum extents of encroachment. While sites with implemented municipal post and fence policies had significantly lower mean frequencies, intensities and, in the case of fences extents of encroachment, they were not significantly different from those of sites under some of the boundary types not subject to municipal policies. They were also significantly higher than those of sites with fences and grass strips (with or without pathways). Sites with municipal posts had significantly lower mean intensities of encroachment than sites with other boundaries that enabled residents to enter the forest edge, and had significantly lower mean frequencies of waste disposal traces than fenced sites. Sites with fences also had significantly lower mean intensities of encroachment than sites with no boundary demarcation, or sites with fences and gates, and were particularly effective in reducing the incidence of yard extension encroachments, and mean maximum extents of encroachment. Despite the effectiveness of these boundary demarcation policies, and that of some of the other boundary treatments evaluated, none of the boundary treatments was effective in eliminating encroachment traces. A buffer of between 10 and 20 metres in width would be required to segregate the mean maximum extent of encroachment activities from sensitive forest edges, depending on the boundary demarcation policy, or type. The research concludes that current municipal policies are insufficient to meet the complexity and scope of the encroachment activities occurring. Some preventative policies have been developed and are regularly implemented within natural areas adjacent to new subdivisions. However, implemented boundary demarcation policies are insufficient to eliminate, or minimize residential encroachment. Wider more complex boundary policies that limit different types of encroachment and include elements that reduce access, spatially separate, and encourage informal residential surveillance (such as fences, grass strips and pathways) can further reduce encroachment levels. Few municipalities have established boundary demarcation policies to prevent encroachment within natural areas adjacent to established subdivisions, and study municipalities infrequently implement policies and bylaws to mitigate existing encroachments within these areas. Yet interviewees, and the results of the unobtrusive measurement of encroachment in study forest edges, indicate that encroachment activities are highly prevalent within these municipal forests. Policies at all levels, and particularly at the official plan level, are required to protect natural areas from edge resident encroachment, and other forms of post development impacts on natural areas. These policies are required to support the more rigorous enforcement of encroachment bylaws, and the negotiation, and implementation of effective buffers and boundary demarcation treatments. In consideration of these results and conclusions, the dissertation describes the implications for municipal planning policy and urban and regional planning theory, and provides recommendations for future research.
