Effects on Boston's Urban Biodiversity

Holland, Kelly John January 2003 (has links)
Thesis advisor: David Krauss / In an attempt to better understand the biodiversity of an urban ecosystem, we have conducted plant and bird biodiversity assessments of 10 sites in the Greater Boston area from September 2002-April 2003. These sites have been identified by the Urban Ecology Institute as important green areas through the Natural Cities Program. The purpose of this program is to create a greater body of knowledge of urban green spaces and the greater urban ecosystem of Boston. Our objective was to quantify plant and bird biodiversity by focusing on species richness. We then compared this biodiversity information to various factors such as area of impervious surface, and area of maintained lawn. Our analysis did not demonstrate statistically significant relationships between these factors. / Thesis (BS) — Boston College, 2003. / Submitted to: Boston College.

Revealing Promising Pathways for Increasing Urban Ecosystem Services: An Approach Combining Stakeholder Priorities with Ecosystem Service Quantification

Elderbrock, Evan 11 January 2019 (has links)
Urban development diminishes the delivery of ecosystem services (ES), defined as benefits from ecological processes and functions critical to human health and well-being. Land-use planners and environmental managers are increasingly familiar with the concept of ES; however, methods for incorporating ES into urban planning are underdeveloped. While previous reports have identified the combination of ES quantification and stakeholder engagement as necessary for increasing the delivery of ES, methods of implementation remain unexplored. To address this disparity, this study combines ES quantification with perspectives from multiple stakeholders to identify specific land cover conversion scenarios that increase the delivery of ES in the Friendly Area Neighborhood of Eugene, Oregon and compares each conversion scenario using an informed weighting system. The result is a method, with potential for use by researchers and public officials, to quantify the delivery of ES, identify stakeholders’ ES priorities, and assess the benefits associated with green infrastructure development. / 2020-01-11

As aves, consideradas bioindicadores, têm sido intensamente estudadas em áreas urbanas. O objetivo deste estudo foi avaliar a riqueza e a abundância da avifauna na área urbana de Bauru (SP), bem como verificar como diferentes coberturas vegetais podem interferir na comunidade de aves. A avifauna foi amostrada entre dezembro de 2014 e novembro de 2015 em quatro áreas, sendo três condomínios residenciais e um campus universitário. As observações ocorreram mensalmente em cada uma das áreas, sendo uma hora no período matutino e uma hora no período vespertino. O método utilizado foi o transecto linear com duração de 60 minutos, totalizando 96 horas de observação. Em todas as áreas foi realizada a caracterização da cobertura vegetal arbórea como número de espécies e de indivíduos utilizando amostras de vegetação paralelas aos transectos. Foi observado que a riqueza de aves aumentou com a riqueza da vegetação. Além disso, as áreas mais urbanizadas e com menor diversidade vegetal estiveram relacionadas com alta abundancia e poucas espécies de aves. Sugerindo que uma maior riqueza da cobertura arbórea, mesmo em áreas centrais das cidades, pode auxiliar na presença da avifauna. / Urbanization alters the composition and diversity of biotic community, therefore ecological research has been conducted in the cities in order to recognize its impacts. The birds, considered bioindicators, have been intensively studied in urban areas. The objective of this study was to evaluate the richness and abundance of avifauna in the urban area of Bauru, state of São Paulo (SP), Brazil, as well as verify how different vegetation covers may interfere with the bird community. The avifauna was sampled between December 2014 and November 2015 in four areas: three residential condominiums and a university campus. The observations were monthly held in each of the areas, one hour in the morning and one hour in the afternoon. The method used was linear transect with a duration of 60 minutes, totaling 96 hours of observation. In all areas, it was carried out the characterization of arboreal vegetation cover, as for the number of species and individuals, using parallel vegetation samples to transects. It was observed that the richness of birds increased with the richness of vegetation. In addition, more urbanized areas and with less plant diversity were related to high abundance and a few species of birds. Suggesting that the richness of arboreal covering, even in central areas of cities, may assist in the presence of avifauna.

They are the defining ecological phenomenon of the twenty-first century. Natural patterns and processes within cities might be a means toward an ecological regeneration of their bioregions through a symbiotic relationship between them. In this context, design has a great potential to reshape cities, transforming them for improved living conditions and balanced ecological systems. Considering buildings and landscapes as reciprocal entities within a system is a great opportunity for design innovation and increased performance with an active engagement between people and nature. By assuming the ecosystem services approach as a reference for highest ecological performance when multiple ecosystem services are provided within a system, this dissertation proposes an urban ecosystem services framework and the concept of service providing design for assessing architecture and landscape architecture. This framework is the basis to analyze three rating systems that are the most relevant standards for sustainable and regenerative design of architecture and landscape architecture, being the Living Building Challenge â , LEED â , and Sustainable SITES Initiative â . Furthermore, two architecture and landscape architecture certified and high-performance projects are analyzed. Based on the analysis, other ecosystem services beyond those proposed in the framework are identified, being renewable energy sources and active living. Some ecosystem services considered are not required by the rating systems, and not provided by the projects, being medicinal resources, pollination, and spiritual experience. Although required, food production is not provided in the projects studied due to a scale issue as they are located in densely occupied urban sites. Moreover, SITES is currently more related to ecosystem services than LEED, which suggests that the ecosystem services framework has a great potential as a tool to explore the relationship of building design criteria and natural systems and cycles. Although most ecosystem services are identified as provided by the two assessed projects, their performance suggests that they are not yet fully integrated to the natural ecosystem. This fact corroborates to the necessary next step for defining the Urban Ecosystem Services Framework in a quantitative approach with a hierarchical organization of the ecosystem services. Rigorously addressing the ecosystem services approach in LEED, SITES, and other rating systems will help integrate ecological regeneration processes in architecture, landscape architecture, and cities.

Investigations on Urban Ecosystem Services provided by Urban Parks and Interactions with Dwellers in the center city of Shanghai, China

Zhao, Liang 21 July 2016 (has links) (PDF)
Under global urbanization backgrounds with physical population migrations and relocations, corresponding consequences in society developments, cultural transformations, technology inventions and interactions between regions and countries, etc. are considered as having a huge impact on normal urban dwellers. For human beings always have intentions towards managements and benefits from natural surroundings, urban dweller demands under the modern challenges and their interactions are necessary to be concerned about. Urban ecosystem is considered as a highly developed civilization, but also with features of resources and energy demands and pollution and distributional exports. As the only natural element in this ecosystem, UGI (urban green infrastructures) is considered as an important human-environment interaction provider with urban ecosystem services (UES) largely focused by academic scholars, urban planners and policy managers. As one of the fastest urbanizing cities in the world, Shanghai is considered as having huge cultural and social developments combined with socioeconomic acceleration. Under the unique background of policy planning and traditional Confucian culture transformation, the impacts to urban dweller demands, whether these newly developed modern demands can be satisfied by UES provided by UGI and how the understandings of these normal dwellers to UGI in Shanghai are necessary for academic researches. By considering the interactions with urban dwellers, six urban parks in the center of Shanghai are chosen as research sites in this study. Combined with factors of urbanization processes and observed patterns of visitor interactions, the indicator of “park age” is concerned with three old parks (older than 25 years old) and three new parks (younger than 25 years old). With methodologies of fieldwork mapping, questionnaires, indicator based evaluation system constructions, etc., the quantitative and qualitative analyses were carried out to habitat diversity, cultural and regulation UES results, and the background reasons caused by political and financial influences are subject to further discussion. The visitors to urban parks of Shanghai are classified into four sorts: “retired dwellers”, “dwellers for children care”, “tourist visitors” and “other visitors”, we found out that related demands and interactions with urban parks have significant differences. After detailed discussions, it could be figured out that the visitors demands play a significant role, and the interactions between visitors and UES in Shanghai are comprehensively influenced by multiple factors of “visiting objectives”, “park cultures (ages, popularities, etc.)” and “personal identities (educations, incomes, etc.)”. Based on this, the detailed differences of policy, finance, Confucian culture, nature understanding, and community society between old and new parks were further discussed. With all aspects of physical, mental, psychological and other demand aspects especially focused on, the typical features in Shanghai are also highly concentrated on dominant activities. For China is suffering from national environmental and urbanization problems but lack in related concerns combined with dweller demands, this research work may make certain efforts on model assessment methodologies constructions and national implementations. Also, with a combined background of top-down policy systems and natural understandings under socioeconomic duress, this research could also make significant efforts in dweller-UES interactions researches in similar cases of other countries and newly developed urban ecosystems in the world.

Environmental Performance Of Urban Patterns In Terms Of Their Ecological Footprint

Tanrikulu, Melda 01 June 2010 (has links) (PDF)
Within the twenty&ndash / first century, nearly three billion people, half of total population of the world, live in cities. It is estimated that in the forthcoming twenty&ndash / five years, two billion more people will settle in urban lands. Essentially most of these devastating changes will occur in developing countries, both in terms of the total global urban population as well as increased percentage of the individual country&rsquo / s population living in urban areas. For many developing countries, the urban population is already large. Further increases in size and rates of growth will no doubt stress already impacted environments and living quality. All cities, however, are not impacting the ecology of the world similarly. On the one hand, developed cities have mostly cope with their environmental problems regarded as traditional / concern has focused to their impacts on ecosystems as well as those larger in scale. Cities in the developing world are more concerned with other issues. However, it is not only the development level of countries but the urban planning and development tendencies of their cities impacting the environment differently should be considered, which comprehensively shows us environmental performance of urban patterns. Environmental performance basically refers to the abilities and capabilities of urban patterns to mitigate their impacts on environment and ecology of the world and to cope with the negative of all. As an indicator of environmental performance of urban patterns, ecological footprints, its reasons and long term effects should be specified as inseparable part of urban development and inevitably ecological footprints of different urban patterns and their effects on climate change should be concerned while taking planning and development decisions for urban areas. The basic purpose of the thesis is to specify the environmental performance of different urban patterns in terms of their ecological footprints through defining the relationship between implications of urban patterns and their contributions to the ecological footprint.

No. of bitstreams: 1 parte1.pdf: 1436338 bytes, checksum: 079676a21abf797e76c98dd2332b3235 (MD5) Previous issue date: 2010-03-03 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / The constructions and reconstructions of urban spaces are not just a result of pressure pressing socio-economic system. They are also the result of ideological models on the "development" and "modernity" that are imposed on holders of power. Inserted in this problematics and going under strong pressure due to various ways of soil use and occupation, worldwide, the costal zones can be considered regions of contrast, constituting a privileged field, as well as a challenge in terms of different environmental management strategies. In this scenery, the urban and environmental plan represents an important tool of analysis and urban management. It is necessary an ecosystem approach, based on the principle of complexity, a holistic view of the city, in which all the elements, including the human societies, become part of a big net of relations. This academic study identifies, based on the present situation, the physical, environmental and legal compatibilities and incompatibilities, elaborating strategies for the use and occupation of soil in growing urban areas in the district of Jacumã, located in Conde city, state of Paraiba. Such analysis was performed taking into consideration a methodology proposed by McHarg (1972). As results, the research points to the extreme inefficiency and lack of basic infrastructure (water supply, sanitation, access to public transport, garbage collection and sites for leisure), and demonstrates serious environmental impacts related to uncontrolled urban expansion expressed in occupations in areas of environmental preservation. The creation of an indicator of environmental suitability in this study allowed the quantification and verification of a synthetic form of the incompatibility of current and future occupations. The procedures elaborated for such goal intend to contribute to the policies of sharing, use and occupation of soil as well as the urban strategies that rule those actions and that have an important role in conducting the cities in this process of sustainability. / As construções e reconstruções dos espaços urbanos não resultam apenas de uma pressão imperiosa do sistema socioeconômico. Elas também são o fruto de modelos ideológicos sobre o desenvolvimento e a modernidade que se impõem aos detentores de poder. Incluída nesta problemática e submetida à forte pressão por intensas e diversas formas de uso e ocupação do solo, a nível mundial, as Zonas Costeiras podem ser consideradas regiões de contrastes, constituindo-se num desafio para o exercício de diferentes estratégias de gestão ambiental. Nesse cenário, o planejamento urbano ambiental surge como ferramenta essencial de análise e gestão urbana. Sendo necessária uma abordagem ecossistêmica, uma visão holística da cidade, trazendo consigo o Princípio da Complexidade, na qual todos os elementos, incluindo as sociedades humanas, interagem numa gigantesca rede de relações. O presente trabalho identifica com base na situação atual, as compatibilidades e incompatibilidades físico-ambientais e legais, e elabora diretrizes para o uso e a ocupação do solo nas áreas de expansão urbana do Distrito de Jacumã, localizado no município do Conde, Paraíba. Esta análise foi feita a partir da metodologia proposta por McHarg (1972). Como resultados a pesquisa aponta para a extrema carência e ineficiência de infra-estrutura básica (abastecimento de água, esgotamento sanitário, acesso a transportes públicos, coleta de lixo e áreas destinadas ao lazer), além de demonstrar sérios impactos ambientais relativos a expansão urbana desordenada expressos nas ocupações em áreas de preservação ambiental. A criação do indicador de adequabilidade ambiental nesse trabalho permitiu a quantificação e a verificação de forma sintética da incompatibilidade das ocupações atuais e futuras. As diretrizes elaboradas pretendem contribuir com as políticas de parcelamento, uso e ocupação do solo e as práticas urbanísticas que viabilizam estas ações e que possuem papel efetivo na meta de conduzir as cidades no percurso da sustentabilidade.

Ecossistemas urbanos no ensino de ecologia: uma experiência em escola do entorno da APA Morro do Urubu, Aracaju, SE

Santos, Thisciane Ismerim Silva 15 March 2017 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / The disorderly growth of urban areas, stimulated by the industrialization process, has generated social, economic, cultural and environmental problems. It is necessary to analyze cities as urban ecosystems highly dependent on natural ecosystems. Therefore, it can be said that this relationship is harmful, since the resources extracted from the natural to the urban environment are not always replaced and the waste produced in the cities is not recycled for the most part. This fact results in the degradation of the environment, which harms not only the remnants of natural ecosystems in them still inserted, but also the quality of life of their populations. In this context, the school can contribute to the formation of critical citizens and committed to maintaining the quality of the environment in which they live. For this reason, the main objective of this research was to evaluate the contribution of the approach of urban ecosystems in the school Ecology education of the state education network, located in the vicinity of the Environmental Protection Area Morro do Urubu, in the city of Aracaju, SE. In order to do so, a didactic sequence was constructed and evaluated, which included three stages: 1) Pre-construction, in which Biology teachers and high school students in the school (s) in question were consulted in order to necessary information for the preparation of the material; 2) Construction proper of the prototype of the didactic sequence; and 3) Postconstruction which, in turn, was divided into three moments: pre-evaluation of the prototype by teachers of Biology of Basic Education and Higher Education for its improvement and adequacy; application of this didactic material in the 3rd year of high school in one of the participating schools; and final evaluation by students and teacher of Biology responsible for the class. The inclusion of urban environments in the teaching of Ecology seemed to be well received by teachers of Biology, since they consider most of the contents of this science susceptible to this approach. The students showed a greater interest in areas that involve human biology, an optimistic data for the proposal of inserting the human species in the subjects of Ecology as one of the elements belonging to ecological relations. In addition, these students showed little knowledge about the APA in question. From these and other information obtained by these subjects, the teaching sequence proposal consisted of five classes that deal with the following topics: Ecological concepts; Biogeochemical cycles; Chain and Food Web; Ecological Relations; and Ecology of Populations and Communities. In all these classes, urban and local ecosystems are presented as part of the reality of the students involved, in order to contextualize the content of Ecology and sensitize them about the environmental problems that occur in this region. After the improvement made in the didactic sequence based on the criticisms and suggestions of the two groups of teachers participating in the research, this material was applied and evaluated by the students and the teacher in charge of the class. The classes were applied in eight meetings. Despite some setbacks to the development of the proposed activities, such as the time available, the structure of the school and the lack of interest of some students in the class to participate in the discussions, it can be said that this didactic sequence has a certain potential for the learning of ecological content to make sense to students. This is because the vast majority of these have evaluated activities satisfactorily, taking into account the interaction, dynamics and learning of new knowledge. In addition, it can be seen that, at the end of the interventions, some of them managed to perceive themselves as integrators and transformers of ecosystems, insofar as, both in the assessments of activities and in their considerations about what they called them the most attention in the subjects of Ecology and in the application of this science in everyday life, have made relations between human beings and the environments in which they live, especially the urban. / O crescimento desordenado das áreas urbanas, estimulado pelo processo de industrialização, gerou problemas sociais, econômicos, culturais e ambientais. É necessário analisar as cidades como ecossistemas urbanos altamente dependentes dos ecossistemas naturais. Sendo assim, pode-se dizer que esta relação é prejudicial, uma vez que os recursos extraídos do ambiente natural para o urbano nem sempre são substituídos e os resíduos produzidos nas cidades não são reciclados em sua maior parte. Esse fato resulta na degradação do meio ambiente, o que prejudica não só os remanescentes de ecossistemas naturais neles ainda inseridos, mas também a qualidade de vida de suas populações. Nesse contexto, a escola pode contribuir para a formação de cidadãos críticos e comprometidos com a manutenção da qualidade do meio em que vivem. Por esta razão, o objetivo principal desta pesquisa foi avaliar a contribuição da abordagem de ecossistemas urbanos no ensino de Ecologia de escola da rede estadual de educação, localizada nas proximidades da Área de Proteção Ambiental Morro do Urubu, na cidade de Aracaju, SE. Para isso, foi construída e avaliada uma sequência didática que contou três etapas: 1) Pré-construção, em que professores/as de Biologia e alunos/as do Ensino Médio da/s escola/s em questão foram consultados/as, no intuito de obter informações necessárias para a elaboração do material; 2) Construção propriamente dita do protótipo da sequência didática; e 3) Pós-construção que, por sua vez, foi dividida em três momentos: pré-avaliação do protótipo por professores/as de Biologia da Educação Básica e do Ensino Superior para o seu aperfeiçoamento e adequação; aplicação desse material didático em turma do 3º ano do Ensino Médio de uma das escolas participantes da pesquisa; e avaliação final por parte de discentes e de docente de Biologia responsável pela turma. A inserção dos ambientes urbanos no ensino de Ecologia pareceu ser bem recebida pelos/as professores/as de Biologia, na medida em que consideram a maioria dos conteúdos dessa ciência suscetíveis a essa abordagem. Os/as discentes demonstraram maior interesse por áreas que envolvem a biologia humana, um dado otimista para a proposta de inserir a espécie humana nos assuntos de Ecologia como um dos elementos pertencentes às relações ecológicas. Além disso, estes/as alunos/as demonstraram pouco conhecimento a respeito da APA em questão. A partir destas e de outras informações obtidas por esses sujeitos, a proposta de sequência didática consistiu em cinco aulas que abordam os seguintes temas: Conceitos ecológicos; Ciclos Biogeoquímicos; Cadeia e Teia Alimentar; Relações Ecológicas; e Ecologia de Populações e Comunidades. Em todas essas aulas, os ecossistemas urbanos e locais são apresentados como parte da realidade dos/as alunos/as envolvidos/as, a fim de contextualizar o conteúdo da Ecologia e sensibilizá-los sobre os problemas ambientais que ocorrem nesta região. Após a melhoria realizada na sequência didática a partir das críticas e sugestões dos dois grupos de docentes participantes da pesquisa, esse material foi aplicado e avaliado pelos/as alunos/as e docente responsável pela turma. As aulas foram aplicadas em oito encontros. Apesar de alguns contratempos para o desenvolvimento das atividades propostas, como, o tempo disponível, a estrutura da escola e a falta de interesse de alguns/as alunos/as da turma em participar das discussões, pode-se dizer que essa sequência didática possui certo potencial para que a aprendizagem dos conteúdos ecológicos faça sentido aos/as estudantes. Isto porque a grande maioria destes/as avaliaram as atividades satisfatoriamente, levando em consideração a interação, a dinâmica e a aprendizagem de novos conhecimentos. Além disso, pode-se perceber que, ao final das intervenções, parte deles/as conseguiu percebe-se como integrantes e transformadores dos ecossistemas, na medida em que, tanto nas avaliações das atividades, como em suas considerações sobre o que lhes chamaram mais atenção nos assuntos de Ecologia e na aplicação desta ciência em no cotidiano, fizeram relações entre os seres humanos e os ambientes em que vivem, principalmente, o urbano. / São Cristóvão, SE

Urbana ekosystemtjänster : En evidensbaserad genomgång av urbana ekosystemtjänster och implementering i Slakthusområdet

Berkevall, Catrine, Cerna, Jessica January 2021 (has links)
More than 3,5 billion people currently lives in cities, a number that is expected to increase further. The densification of cities makes it increasingly difficult for people to access natural areas, at the same time as biological diversity is threatened. In this study, we highlight the importance of urban ecosystem services through social and ecological aspects. This study presents a summary of different evidence-based solutions that contribute with urban ecosystem services. It moreover uses a case of urban development in Slakthusområdet (Meatpacking district), Stockholm, in order to describe contemporary processes that integrate solutions that contribute to urban ecosystem services. The results show that there are challenges in implementing these solutions with respect to political, economic, and market factors. The study thereby identifies how examining authorities and policy demands on a green factor tool enable ecosystem service solutions. By studying ecosystem services as part of a social-ecological system, this study ultimately contributes with knowledge on the execution of multifunctional solutions, which are becoming ever more important with the densification of cities around the globe. / Över 3,5 miljarder människor är idag bosatta i städer, och i framtiden förväntas den siffran öka. Förtätningen av städer försvårar människornas tillgång till naturområden samtidigt som den biologiska mångfalden hotas. I den här studien understryker vi de urbana ekosystemtjänsternas roll utifrån sociala och ekologiska aspekter. Härigenom presenterar den här studien en sammanställning över olika evidensbaserade gröna lösningar som bidrar med urbana ekosystemtjänster. Vidare tar den här studien avstamp i stadsutvecklingen av Slakthusområdet i Stockholm i syfte om att studera samtida processer kopplat till implementeringen av lösningar som bidrar med ekosystemtjänster. Resultatet pekar på att det finns utmaningar för implementering av lösningar som bidrar med ekosystemtjänster kopplade till ekonomi, politik och marknadslösningar. Därigenom identifieras kravet för grönytefaktor (GYF) och de granskande myndigheternas arbete med möjligheter för implementering av gröna lösningar. Genom att studera ekosystemtjänster som en del av ett social-ekologiska system bidrar den här studien med kunskap om tillämpningen av mångfunktionella lösningar, vilka blir allt viktigare i och med den ökade förtätningen av städer.
