Clima urbano e vegetação: estudo analítico e prospectivo do Parque das Dunas em Natal

The present study deals with the relationship between urban vegetation and climate. The process whereby the Parque das Dunas a 1,172 ha green area in the city of Natal, State of Rio Grande do Norte exerts influence on the climate of the city is analyzed. The hypothesis on which the present work rests is that the green area referred to acts upon the climate of the city. The study is based on the analysis of climatic factors and elements of this green area and of the city of Natal. In order to give rise to final recommendations, a methodology grounded on a quantitative and qualitative standpoint has been used. The data were collected both within and without the limits of the Parque das Dunas area. Secondary and primary data resulting from the measurements taken by the researcher and her work group have been used. The aim was to contribute to the understanding of the influence of vegetation on the climate of a city having a warm and humid climate. A historical and environmental characterization of the Parque das Dunas was then sought. The local climatic factors and the elements of the climate have been studied within the scope of the city of Natal. A comparative study between the climatic elements within and without the limits of the Parque das Dunas area from the survey of technical data and the systematization of the information collected has been made, aiming at proposing a set of bioclimatic recommendations for the urban design in Natal. The results of such work allowed for the validation of the important role that the Parque das Dunas plays in the climate of Natal. This has led to the acknowledgement of the relevance of the green areas on the climate of cities. They bring about important benefits to the process of rendering agreeable the climate in the urban environment by providing pleasant microclimates that give a valuable contribution to the environmental comfort of urban nuclei having the same size of Natal

O Plano Diretor como instrumento de gestão da cidade: o caso da cidade de Fortaleza/CE

According to article 182 of the Brazilian Federal Constitution, cities should perform social function, what brings the concept that the city should be a place for one to live well. For that to happen, it should be well administered by its public managers. However, so that there is a sound administration, one that really performs that social function, there must be, first, an efficient planning. We understand that such a thing occurs when the master plan is the main planning instrument of a city and serves as basis for its administration. We notice, however, that in most of the cities the master plan is formulated as a law that regulates urban planning but that both the population and the government most of the times are not aware of its importance concerning the relevant issues related to municipal administration, such as its relationship with the economy, taxation, the social issue, land use regulation, and, in summary, with all the aspects that constitute and that a municipal government should manage in the best possible way. One also knows that, in general, the attempt of city planning has always been connected to the duration of a mandate and that way public managers many times implement restricted measures aiming to just attain a political-electoral objective and publicizing their administration. That implies actions and works that in some cases have negative impacts or ones that cannot be removed from the cities. This study intends to show that the master plan should be the planning instrument guiding the municipal administration but that, however, what we note is a lack of connection between that instrument and the government guidelines of the municipal managers. In order to study what happens to the cities that have a planning which is not taken into account in its administration, we will use the city of Fortaleza, capital of the State of Ceará as a case study. Historically, in Fortaleza the public managers have seldom decided to administer the city in according to the master plans developed for it. We should emphasize that planning begins in the city quite late and until the current days it is being substituted by temporary measures. Through the analysis of the planning process and of the urban management of the city of Fortaleza, especially the master plans predicted since 1933, we explain that if such plans had been implemented, they could have been important tools for its administration to attain a social function, becoming therefore a place for one to live well

Wildlife as a Priority in Park Development: A Study of Illinois Park Professionals

The purpose of this thesis is to consider the factors that impact decision making in city park settings, with specific emphasis given to wildlife. Additionally, professional bias was considered as a possible response determinant. Studies connecting perceptions of wildlife and Illinois park managers have been rare or nonexistent, but offer the potential for the improvement of management strategies and recreational opportunities. Data was collected using mixed methods. City recreation practitioners statewide were invited to complete a self-administered questionnaire considering wildlife as a decision-making factor in land acquisition or restoration decisions. A small follow-up sample of park managers was interviewed via telephone for further explanation of their response. Analysis of responses from questionnaires and interviews suggested that wildlife habitat is a factor in land use decision making, but is not considered one of the highest importance. Respondents identified that nuisance wildlife, access to wildlife, and public value of wildlife were also factors in decision making. Factors associated with a high-ranking of the importance of wildlife were agencies with a high number of natural area acres, a high number of overall park acreage, personnel devoted to natural area management, the presence of hiking trails, and cities with a large population. Professional bias of recreation managers was suggested via anecdotal interview data, but could not be empirically connected with wildlife-related decision-making processes, as no managers identified themselves as having completed formal wildlife-related training. As a result, management implications include separate training for both practitioners and public. This study broadens the understanding of wildlife management in city park settings, and reaffirms that further understanding of public and pracitioner values of wildlife will lead to improved land use decisions and recreationally valuable experiences.

MSW: from pollution/degradation source to resource

Municipal Solid Waste is one of the biggest challenges that cities are facing: MSW is considered of the main sources of energy consumption, urban degradation and pollution. This paper defines the major negative effects of MSW on cities and proposes new solutions to guide waste policies. Most contemporary waste management efforts are focused at regional government level and based on high tech waste disposal by methods such as landfill and incineration. However, these methods are becoming increasingly expensive, energy inefficient and pollutant: waste disposal is not sustainable and will have negative implications for future generations. In this paper are proposed all the principle solutions that could be undertaken. New policy instruments are presented updating and adapting policies and encouraging innovation for less wasteful systems. Waste management plans are fundamental to increase the ability of urban areas effectively to adapt to waste challenges. These plans have to give an outline of waste streams and treatment options and provide a scenario for the following years that significantly reduce landfills and incinerators in favor of prevention, reuse and recycling. The key aim of an urban waste management plan is to set out the work towards a zero waste economy as part of the transition to a sustainable economy. Other questions remain still opened: How to change people’s behavior? What is the role of environmental education and risk perception? It is sure that the involvement of the various stakeholders and the wider public in the planning process should aim at ensuring acceptance of the waste policy.

Decrecimiento y renovadas estrategias para un territorio agotado. El caso de la provincia de Alicante

Las consecuencias del último boom inmobiliario han abierto el debate alrededor del crecimiento urbano en España, especialmente en áreas con una fuerte presión turística y residencial. En este trabajo se analizan algunas de las implicaciones de la crisis financiera mundial sobre la planificación urbanística municipal, centrando el estudio en la provincia de Alicante, uno de los ámbitos que mejor ilustran el éxito y la caída del modelo inmobiliario hispano. La unidad básica de análisis la componen las figuras de planeamiento municipal y estrategias territoriales vigentes, y su traducción en suelos urbanos inconclusos. Considerando que se trata de actuaciones durmientes a la espera de un contexto económico favorable, la situación hace pensar que la burbuja inmobiliaria no estaría estallada sino tan sólo desinflada. El objetivo es reflexionar, con carácter propositivo, sobre las estrategias de gestión del territorio que emergen durante los últimos años a raíz de la crisis financiera e inmobiliaria, tratando de relanzar algunas cuestiones que deberían preocupar en la planificación urbanística y territorial de la provincia de Alicante, y por extensión, de otros espacios afectados por el crash inmobiliario.

Análisis del proceso de expansión del oriente de Cali: el caso de Ciudadela Desepaz

Los resultados morfológicos del Programa de Vivienda de Interés Social Ciudadela Desepaz se caracterizan por la desarticulación y baja funcionalidad del espacio urbano. Esta condición urbanística no deriva de una falta de planificación integral, ya que el Municipio de Santiago de Cali evidenció la intención de desarrollar una porción de ciudad bien articulada, sino más bien de un conjunto de factores de los procesos de gestión urbana y urbanística llevados a cabo en este Programa. A partir de una investigación juiciosa de estos procesos, y del análisis morfológico de cada de uno de los proyectos que conformaron la Ciudadela, se definieron 6 factores principales de la gestión que incidieron en que la intención inicial del Municipio no se pudiera materializar.

Alternativas para el manejo de aguas pluviales en medios urbanos. Estudio de caso : implementación y manejo de los canales pluviales en las cuencas del Salitre y Tintal en el marco del proceso de recuperación Río Bogotá 2000- 2014

Los canales pluviales han cobrado vital importancia para el manejo ambiental de las ciudades, al hacer parte del sistema hídrico, brindar servicios ambientales y facilitar el drenaje de las aguas lluvias, principalmente. Sin embargo, se quiere trascender la visión ingenieril de ser estructuras encargadas exclusivamente del transporte de aguas lluvias. El objetivo de esta investigación es analizar las políticas y las acciones implementadas en el manejo de estos canales en Bogotá desde el 2000 hasta el 2014, para revisar las intervenciones realizadas con la finalidad de proponer alternativas que además permitan cumplir con lo ordenado en la sentencia del Consejo de Estado, sobre la recuperación del Río Bogotá. El resultado de este estudio evidenció que aunque no se han llevado a cabo las acciones críticas de adecuación de los canales se ha avanzado en el fortalecimiento institucional y la coordinación inter sectorial para el desarrollo de acciones de gestión integrales. Al final se plantea algunas acciones para el manejo de los canales entre las que se destacan (i) ser integrales y en coordinación con programas ambientales, de espacio público y de gestión del riesgo; (ii) ser coherentes con los nuevos sistemas de gestión de las aguas urbanas; y (iii) fomentar la apropiación ciudadana de los elementos hídricos.

Relationships between airborne pollen allergens and environmental factors.

This thesis is a collection of scientific papers resulting from my research activity during the PhD course in Earth, Life, and Environmental Sciences. The main subject of the thesis is the capability of pollen to trigger a hypersensitive reaction in different environmental conditions, and the need to better characterise such allergenicity in order to measure it. This topic is discussed from different perspectives, using ecological, morphological, and molecular approaches. The thesis starts by summarising the importance of green infrastructures in the cities, from economical and conservational perspectives. It then focalises on the lesser-known ecosystem disservices urban vegetation can provide, and in particular on pollen allergy, exploring its causes and illustrating possible ways to monitor, foresee, and mitigate the allergenic risk. The possibility to monitor the allergenicity of urban green areas is then examined in depth, with an original research paper that proposes a method standardisation for existing allergenicity indices (Specific Allergenic Index and Urban Green Zones Allergenicty Index), and compares the indices results to evaluate their effectiveness. At the end of the thesis, pollen allergenicity is also approached from a molecular perspective, by investigating pollen allergens release mechanisms in the context of pollen hydration and germination. In particular, in an unpublished original research paper, the nature of allergen-carrying extracellular nanovesicles (pollensomes) released by pollen is extensively studied on a non-allergenic pollen model, to understand their biological role and thus the environmental conditions that trigger their release. Moreover, the last paper reported in the thesis demonstrates the secretion of a potential pollen allergen, a low-molecular weight cyclophilin, during pollen germination under stressful conditions. The thesis concludes with a brief description of other scientific activities carried on during the PhD, that still need more scientific corroboration to be published.

Monitoring the composition and form of urban environments based on the vegetation-impervious surface-soil (VIS) model by sub-pixel analysis techniques

The majority of the world's population now resides in urban environments and information on the internal composition and dynamics of these environments is essential to enable preservation of certain standards of living. Remotely sensed data, especially the global coverage of moderate spatial resolution satellites such as Landsat, Indian Resource Satellite and Systeme Pour I'Observation de la Terre (SPOT), offer a highly useful data source for mapping the composition of these cities and examining their changes over time. The utility and range of applications for remotely sensed data in urban environments could be improved with a more appropriate conceptual model relating urban environments to the sampling resolutions of imaging sensors and processing routines. Hence, the aim of this work was to take the Vegetation-Impervious surface-Soil (VIS) model of urban composition and match it with the most appropriate image processing methodology to deliver information on VIS composition for urban environments. Several approaches were evaluated for mapping the urban composition of Brisbane city (south-cast Queensland, Australia) using Landsat 5 Thematic Mapper data and 1:5000 aerial photographs. The methods evaluated were: image classification; interpretation of aerial photographs; and constrained linear mixture analysis. Over 900 reference sample points on four transects were extracted from the aerial photographs and used as a basis to check output of the classification and mixture analysis. Distinctive zonations of VIS related to urban composition were found in the per-pixel classification and aggregated air-photo interpretation; however, significant spectral confusion also resulted between classes. In contrast, the VIS fraction images produced from the mixture analysis enabled distinctive densities of commercial, industrial and residential zones within the city to be clearly defined, based on their relative amount of vegetation cover. The soil fraction image served as an index for areas being (re)developed. The logical match of a low (L)-resolution, spectral mixture analysis approach with the moderate spatial resolution image data, ensured the processing model matched the spectrally heterogeneous nature of the urban environments at the scale of Landsat Thematic Mapper data.
